“The Next Revolution”Cover (Above)
By supporting critical research, Sandia’s LDRD researchers are making exciting advances in micro- and nanotechnologies. Microsystems are highly miniaturized systems that integrate a number of devices (each on the order of 1 µm to 1 mm in size) representing a range of capabilities (e.g., electronics, mechanics, and optics, among others) onto a single silicon chip. These microsystems represent the next revolution in silicon technology that will lead to new products with combined actuation, sensing, and communication capabilities.
Sandia’s nanosciences LDRD investigations advance the underpinning capabilities that will lead to improved microsystem performance. Nanosciences discoveries enable scientifically tailored materials and lead to revolutionary advances in technology—by building things atom-by-atom or molecule-by-molecule, the production of virtually every human-made product will be revolutionized.
Sandia’s LDRD research enhances the Laboratories’ proficiency in many technical fields in support of its Department of Energy mission to serve extensive national security applications. By understanding and controlling phenomena at multiple levels, researchers are learning to design materials and systems with vastly different sets of properties. As one Sandia scientist put it, “…design possibilities are limited only by one's imagination.”
Cover photos (top right, going clockwise): (1) examining nanoscale behavior, (2) creating the world’s smallest robots, (3) advancing ultrasensitive detection systems, (4) developing novel microfabrication techniques, (5) architecting novel nanomaterials, (6) inventing intelligent microsystems, and (7) investigating nanoclustered catalysts.

Supporting National Security ThroughScience and Technology
Ambassador C. Paul RobinsonPresidentSandia National LaboratoriesSandia National Laboratories FY 2002 LDRD Program ReviewJuly 12, 2001
At a recent budget hearing for the Senate Armed ServicesCommittee (SASC), Senator Reed of Rhode Island asked, “Ikeep hearing a lot about LDRD, that it’s been very much asource of contention. What’s all the fuss about?” The threeDepartment of Energy (DOE) National Nuclear SecurityAdministration (NNSA) laboratory directors in attendance(Bruce Tarter [Lawrence Livermore National Laboratory],John Browne [Los Alamos National Laboratory], and myself,C. Paul Robinson [Sandia National Laboratories]) talkedextensively about LDRD as being “…the lifeblood of theLaboratory.”
The history of LDRD goes back to the Manhattan Projectperiod when the decision was made to establish what are nowthe DOE NNSA labs. The question was, “What can we do,now that we’ve assembled the top scientists, to make sure thatthe defense of this nation will always remain in the hands ofscientists who are at the top of their game?” The answer wasto give creative people some freedom to have ideas, to thinknew thoughts, and to create the leading edge perpetually.Those decision-makers believed that such opportunities wouldkeep the researchers at the top of their game and, along withthat, increased national security would be the result.
When LDRD was first incarnated as the WeaponsSupporting Research Program, funding levels were authorizedup to one-third of the Lab budget—one-third was controlled atthe discretion of the laboratory. However, by the time I arrivedat Los Alamos National Laboratory (LANL) in 1967,discretionary funding was down to twenty percent.
When compared to the various industries that invest inresearch and development (R&D), the DOE LDRD Programfunding level ranks quite low. For example, the highestdiscretionary R&D budgets are around thirty-five percent andare typically found in the software industry. Many electronicsfirms’ R&D budgets are at the twenty percent level. Dr. AlMacLachlan, who was at the DOE briefly and was also theformer Chief Technology Officer at DuPont, makes the point

period . ... The question was,
“What can we do, now that

that at DuPont Research Laboratory, discretionary R&D fundsremain at twenty percent. At the lower range of R&Dinvestment, cement aggregates and bulk materialsorganizations may fund R&D at the two percent level. Thesepercentages help illustrate that the fiscal year 2000 (FY 2000)reduction in the LDRD Program (from six percent to fourpercent) was a real problem for maintaining the world-classR&D at the DOE labs.
When I arrived at Los Alamos, one of the favorite phrasesleft over from Enrico Fermi’s time at Los Alamos was, “…it’snot worthy of being called an experiment unless it’s got atleast a fifty-percent chance of failing.” Failure is how youmove most quickly through the scientific method. R&D is trialand error, and that’s what we are about.
I made a pitch to the senators on the SASC for what Ithink could improve government funding in general. Iexplained that no one today would dare fund a project thatonly has a fifty percent chance of succeeding. In fact, youhardly hear anybody talk about experiments. I can say that,fortunately, the DOE NNSA organization is a delightfulexception. This is in stark contrast to many organizations thatfocus almost entirely on demonstration projects. In today’senvironment, that’s what people want to fund—somethingthat’s a sure success. You can get that kind of short-termsuccess, but you take tiny, tiny baby steps, and you don’tmove to the dramatic stretches of the science, the stretches ofthe mind, to do something new.
We held interesting sessions with Dr. Millie Dresselhaus atlast December’s Science Day at Sandia. Dr. Dresselhausconducted focus groups with a cross-section of the Labs’technical staff, including fresh graduates who’ve just come tothe Lab, post-docs, as well as some mid-career people. Thepurpose of the focus groups was to get feedback on thescientific health of our institution. We were praised for theattitude about LDRD; however, the participants said that theprocess is bureaucratic.
The LDRD process is bureaucratic, but it does providesome sense to a process that, at its heart, is impossible. If youlook at the history of LDRD at Sandia, the potential requestsfor proposals would outspend the monies available by a factorof fifteen. So one of the first things we did was put an extrastep into the process to say, “Please don’t waste a lot of timewriting big proposals.” This pre-proposal stage encouragespeople to submit a short précis of what’s proposed—this helpsus determine what new ideas are the best of the best. Of

course, the “losers” in the process are unhappy, but at leastwe’re more efficient with the time spent in the proposalprocess without sacrificing the quality of proposed research.
In addition, we added another component that hascertainly complicated and put more bureaucracy into theprocess. I claim, however, that this component of our LDRDProgram is an enormous success—the Grand Challengeprojects. Grand Challenges are about team research, aboutmultidisciplinary research, about doing something that noindividual researcher could accomplish alone. Universitieshave the problem of how to teach students to work effectivelyin teams. Our Grand Challenges incentivize people to gettogether to take on things that are much bigger than theycould ever attempt on their own. Blending large ideas togetherwith a lot of specialties is important for us and, I believe,important for the country.
In order to be considered as a Grand Challenge, a proposalmust meet two essential tests (among others): • The proposal must engage multidisciplinary teams
across the Labs.• The proposal must address technical areas that are vital to
the core purpose of the Labs.It is not a question of “If you succeed, will the results be
used?” The results (of Sandia’s research) will be used andthey will revolutionize the nation’s national security.

Ambassador C. Paul Robinson says “…has significantlystrengthened Sandia’s ability to fulfill its mission for theDOE.”
Sandia’s LDRD Program provides the flexibility to investin long-term, high-risk research activities that attract the bestresearch talent from across the Laboratories. LDRD researchprovides an opportunity for this talent to explore innovativescientific and technological opportunities that hold highpotential for payoff in future applications. As a result, LDRDadvances strengthen Sandia’s science and technology base andprovide considerable support to DOE and the Laboratories’mission needs.
Authorized by federal law and implemented under DOEunder DOE Order 413.2A, LDRD is Sandia’s sole source ofdiscretionary research funds. In FY 2001, over 95 percent ofSandia’s LDRD projects provided benefits in basic andapplied research to meet national security challenges.
Program Performance
The FY 2001 LDRD Program funded 295 projects(selected from 1351 possibilities, including ideas andcontinuations) with a program allocation of $70 million. Theprogram was divided into five major investment categories(including subdivisions): • Science and Technology (Advanced Manufacturing,
Biotechnology, Computational and Information Sciences, Electronics and Photonics, EngineeringSciences, Materials Science and Technologies, PulsedPower Sciences)
• Mission Technologies (Energy and Critical Infrastructure, Emerging Threats, Nonproliferation and Materials Control)
• Grand Challenges• Advanced Concepts• Corporate Objectives
Sandia’s LDRD Program utilizes several types ofmeasures to identify research performance, including
• Quality of science, technology, and engineering• Relevance to national needs and agency missions• Quality of research management.
Quality of science is indicated by expert advisorycommittees, peer reviews, sustained progress, and recognition

by the scientific community. Relevance is indicated bysustained advancement of fundamental science and advancesin support of missions. The quality of LDRD researchmanagement is indicated by well-developed researchprocesses, established project goals and milestones, andeffective decision making in managing and redirectingprojects.
Sandia LDRD received significant scientific recognitionfrom industry, government, and professional societies in FY2000 (the latest year for complete results). In FY 2000, two ofthe six DOE Office of Basic Energy Sciences (BES) Awardswere awarded to two Sandia LDRD–related activities:“Nanocluster Catalyst” (FY 1996 project number 3539.270)and “Direct Fabrication of Multifunctional NanocompositesVia Supramolecular Self-Assembly” (FY 2000 project number10406). In addition, citation analysis provides a measure forthe impact of LDRD research advancement. In 2000, SandiaLDRD journal articles across all fields represented 18 percentof all Sandia articles, and over the past five years, SandiaLDRD journal articles outranked overall-Sandia articles interms of relative impact: 1.57 to 1.29 (as measured by theISI’s [Institute for Scientific Information] Science CitationImpact database).
Each foundational LDRD investment area maintainsexternal review boards to provide feedback on researchquality. As an example, LDRD Electronics and Photonicsresearch results were externally peer-reviewed by theMicroelectronics and Photonics External Review Panel onOctober 1–3, 2000. An excerpt from the Panel’s report is
• “…The panel reviewed…photonic crystals, gallium nitride (GaN) science, chemical and biological sensors,radiation-hard microelectronics for weapons andsatellite applications and facilities operations. The presentations established a compelling basis for anoutstanding rating….”
External reviews also provide important perspective andrecommendations on the relevance of LDRD research. As anexample of relevance, the Microelectronics and PhotonicsExternal Review Panel highlighted the support of LDRDresearch to the Labs’ missions:
• “…In summary, the Microelectronics and Photonics capabilities at Sandia provide the opportunity to deliver exceptional service to the nation in broad areas and in changing times...”

The Sandia LDRD Program has developed a process thatencourages Labwide participation (i.e., involves executiveleadership, program directors, and research staff throughoutthe Labs) to produce new knowledge with long-term benefits.Because research outcomes are frequently unpredictable,targeted levels of research performance and milestones cannotbe 100 percent specified beforehand. However, research goalsand milestones are established for each project to inspireextraordinary levels of innovation from the research teams andstaff. As such, each project team is encouraged to create adeliberate mismatch between the group’s research aspirationsand its present knowledge and resources.
The Sandia LDRD Program has been tracking the numberof completed milestones and the number of goals met sincethe early 1990s. Project milestones are determined for every$300K of funding and identify specific accomplishments inthe progression of research. Goals refer to certain capabilitiesthat are desired within the overall framework of a project’sresearch activities. In scientific inquiry, meeting all of theintended goals indicates that the research challenges havebeen set too low.
From FY 1996 through FY 2000, LDRD projectsmaintained a risk balance that resulted in a 69 percent averagecompletion rate for milestones and a 51 percent average ratefor goals met. In addition, the percentage of research goalsmet has declined over the past four years. This provides anindication of the high level of “stretch” anticipated by LDRDparticipants in their research activities.

The LDRD Program’s Impact on Sandia’s Scienceand Technology
A. D. Romig, Jr.Chief Technology OfficerVice President for Science & Technology and PartnershipsSandia National LaboratoriesSandia National Laboratories FY 2002 LDRD Program ReviewJuly 12, 2001
Some of the most fundamental research that we have atSandia, research that has an incredible payoff for the missionsof the Labs, derives from the seeds sown in the LDRDProgram. Investments made ten and fifteen years ago in theLDRD Program are having a direct impact on the weaponsprogram today. At the time when those investments weremade, you would not have been able to make the connectionbetween research activity and future programmaticapplication. But, it is now clear that those investments havedeveloped the technical base for the Laboratories today andwill continue to meet the needs of the nation as we go forwardinto the future.
Funding Research Priorities for a National SecurityLaboratory
Sandia is a national security laboratory. Our nuclearweapons mission accounts for over half of the work at theLabs and truly defines our being. All other program areasdraw from, as well as contribute to, the weapons work at theLabs. Similarly, Sandia’s LDRD Program investment prioritiesreflect our strong emphasis of support to the weapons missionof the Labs. The Science and Technology (S&T) investmentareas (IAs) identify research with a strong coupling to thenuclear weapons program and account for nearly half (i.e.,46.1 percent in FY 2002) of the LDRD annual budget. TheMission Technologies IAs (i.e., Energy and CriticalInfrastructure, Nonproliferation and Materials Control,Emerging Threats, Differentiating Technologies) support theother national security business areas of the Labs and accountfor a little more than one-third (i.e., 36.3 percent in FY 2002)of annual LDRD funding commitments.
The research portfolio for the S&T IAs of the LDRDProgram emphasizes S&T innovation that supports the nuclearweapons stockpile. For example, investments are determined

for very basic research in disciplines, including materials,engineering sciences, and nanotechnology, among severalother areas. For some research investments, the path fromscience to mission can be very long—perhaps a twenty-yeartimeframe to useful adoption. And, of course, there are manyideas that initially seem to have a lot of promise but do notsurvive the trip to eventual application.
In general, however, the basic research efforts produceresults with times to useful adoption of nominally five to tenyears. Results stemming from basic research are oftenintegrated to develop technology with shorter times to usefuladoption—approximately two to five years. As a result, we arecontinually evaluating research efforts to cultivate, nurture,and mature results to the point where they may be identifiedfor the insertion path into weapons and other national securityapplications.
In addition, we make an effort to identify somecrosscutting research efforts between technical disciplines(such as our research efforts with integratedmicrotechnologies) to advance our Microsystems andEngineering Sciences Applications (MESA) capabilities. Webelieve that the high functionality of integrated microsystemswill enable new capabilities and applications that willrevolutionize the capabilities of the nuclear stockpile whileincreasing its safety, security, and reliability.
These very small, highly integrated, and low-powermicrotechnologies are created using integrated circuitfabrication technology that allows the combination of diversefunctions on a single chip. Integrated microsystems mayinclude combinations of sensors, miniature communications,microelectronics for on-board processing, andmicroelectromechanical systems (MEMS) that integrate gearsand action elements fabricated from silicon compounds. In thefuture, integrated microsystems will streamline the number ofweapon components, reduce production and maintenancecosts, and minimize the number of fault points in the weaponssystem.
Grand Challenges (GCs) investments are a key element ofSandia’s LDRD Program strategy. These investments enableus to assemble multidiscipline project teams to focus onsolutions to significant national-level problems andcapabilities. The GC investments receive about ten percent ofthe program funding and are Sandia’s largest LDRD projects.Competition among potential GC proposals is very high.

recommendations for the forthcoming fiscal year’s GCprojects. Their recommendations assess the high-risk, high-payoff proposals based on their potential for impacting aSandia mission or national needs area. Sandia’s µChemLab™is an example of a successful former GC project that hasprogressed the full cycle from research to applications.
Two LDRD Program IAs that receive small fundingamounts are the Advanced Concepts and the UniversityCollaborations IAs. Advanced Concepts investments considertechnical approaches to counter threats that the world and thenation will face over the next decade or two. These very out-of-the-box research activities are unique not only due to thekinds of problems being addressed but also because, in somecases, there are not yet established any programmaticframeworks in which to address the problems. For example,how do we prepare for threats before there is an awareness oftheir damage potential or before there is an organizationalstructure tasked to address it? This is an important focus ofthe Advanced Concepts IA.
Currently, there is no governmental organization taskedwith creating technologies as a way to solve water problemsand to mitigate conflict. You might ask, “Why do we want toworry about water?” Many political scientists point out thatover the next ten to fifteen years, water is as likely (perhapseven more likely) to drive conflict and warfare than are oil orenergy. The Advanced Concepts IA is a tool for the Labs toaddress such threats by capturing them within an overallscientific and technological construct.
With the great explosion of scientific and technologicadvances in recent years, we realize that a lot of our researchactivities cannot be accomplished alone. The UniversityCollaborations IA has been created to explore science andtechnology areas through collaborations with cooperatinguniversities. Sandia recognizes that much expertise inemerging sciences and technologies presently lies withuniversities and industrial organizations. Thus, UniversityCollaborations research activities provide access to world-class, external resources that Sandia requires in order todevelop critically needed research and technical capabilitiesfor the future.

The Future of LDRD
What is the future of LDRD? Before commenting on thefuture, perhaps it would be helpful to briefly review the recentpast. Looking back to the late 1960s, Sandia was makingdecisions about where it thought the future was going to go. Itwas clear then that microelectronics would have a key role inhow weapon systems would evolve. As a result, Sandia madeinvestments in various microtechnologies that laid thefoundation for our expertise in radiation effects in solids (i.e.,that led to the development of rad-hard microelectronics),microoptics, MEMS, sensors, etc. In fact, today we believethat all of these and other similar advances are going to createcontinued advancements and lead to entirely new ways ofmeeting the needs of the stockpile and other national securitymissions through MESA capabilities.
Consistent with the past research strategies, we believethat the LDRD Program is critical for determining currentinvestments that the Labs will be able to capitalize on in thefuture. We are investing now in the emerging fields ofbiotechnology, nanotechnology, and information technology,and especially in the interface of how these disciplines cometogether. As an example, self-assembly processes (which havebeen a focus of LDRD investments since the mid-1980s) arevery much related to fundamental chemical and biologicalmechanisms and provide powerful methods for fabricatingnanoscale devices with great precision. Our evolvingknowledge of self-assembly processes will lead to the creationof new generations of miniature devices and systems. In thefuture, I believe that self-assembly techniques will be used instockpile rebuilds and in the development of other nationalsecurity systems. In fact, our µChemLab™ technology alreadyuses self-assembly techniques to construct materials anddevices to specific requirements.
We are often asked, “How will biotechnology impact theweapons program.” One current example is the extension ofmassively parallel computing architectures used in weaponsmodeling and simulation activities (i.e., based on research thatbegan in LDRD) into various biotech investigations. Otherthan the nuclear weapons program, the big computationalchallenges today are being addressed in the genomics andproteomics biotech areas. Leveraging the investments andinnovations in these bio areas can support the computationaltechnology required by our weapons program. In fact, ourinvestigations into computational technology recently led to

the Cooperative Research and Development Agreement(CRADA) between Celera, Compaq Computer, and Sandia.This collaboration will produce a scalable computerarchitecture that will yield the world’s fastest general-purposesupercomputing design: 10 teraflops by 2002, 100 teraflops by2004, and ultimately, one petaflop.
As another example, a new Sandia Grand Challengeproject for FY 2002 will investigate the application ofbiotechnology to develop small power sources and fuel cellsfor portable applications. Today’s warfighter carries aroundapproximately sixty pounds of batteries to power hisequipment. Imagine the benefits to the warfighter if we couldreduce the weight of those batteries by supplementing orreplacing them with biological microfuel cells for poweringthe equipment. Such fuel cells would utilize body fluids (i.e.,glucose) to support power generation. To make this work,however, we are going to need incredible advancements inmembrane technology. Eventually, fuel cells might be a betterchoice for the stockpile than lithium batteries, but we cannotprove that without the right kind of membrane technology—and that technology may first be developed in thebiotechnology arena.
The LDRD Program Is Critical to the Future of the Labs
Other than technology, the crucial benefit of our LDRDProgram is people—I do not want us to lose sight of this. Twoyoung staff members recently told me that the LDRD Programis one of the reasons they stay at the Labs. While otherresearch organizations have attempted to lure them away, theystay partly because they like the people and the facilities here.But most importantly, they told me, through the LDRDProgram they get to do the kind of research they want to do,and the results of this research impact the future of the nation.The work we do at Sandia, and especially in the LDRDProgram, attracts talented people like these young staffmembers that fuel the capabilities of the Labs.
Without a doubt, the LDRD research activities areabsolutely critical to the future of the Laboratories. ThroughLDRD investments, we conduct research to ensure that theright S&T are available and provide the differentiatingstrengths to meet Sandia’s mission needs. The LDRD Programinvestments prioritize research to serve the nuclear weaponsmission while building competencies for anticipated futurenational security needs.

An Overview of the Electronics and Photonics (E&P)Investment Area
Marion ScottDeputy, Microsystems Science, Technology and Components CenterSandia National LaboratoriesSandia National Laboratories FY 2002 LDRD Program ReviewJuly 13, 2001
The Electronics and Photonics (E&P) LDRD investmentarea (IA) prioritizes research that expands the Labs’capabilities for creating next-generation, integratedmicrodevices and microsystems. These research activitiesdraw upon the Labs’ differentiating strengths and will enablethe Labs to develop future advanced systems for achieving itsnational security missions. In particular, E&P researchadvances will help us to continue to ensure the safety,security, and reliability of the nation’s nuclear weaponsstockpile.
The future of microsystems points to an even higherdegree of integration to create systems that are very small,require less power consumption, and are very low cost tomanufacture. These new systems will ultimately containsensing, processing, mechanical actuation, andcommunications on a single chip. Because of their low costand high functionality, these integrated microsystems will helpus realize entirely new systems and applications.
The Integrated Solutions thrust of the E&P IA addressesinnovative approaches to achieving higher levels ofintegration as well as mixed technology integration. Weencourage research ideas that address advanced packaging,thermal management of microsystems, micro-integrated powersupplies, and integrated photonic systems. Approaches toradiation hardening and other requirements to ensure ruggedperformance of integrated microsystems in abnormalenvironments are also sought. An example of a success of thisresearch thrust is our photonics crystal research that improvesoptical waveguides for communications applications.
Our other E&P research thrust, Microdevices, invests intechnologies with the potential to impact the Labs’ strategicbusinesses’ and weapons’ needs in a three- to five-yeartimeframe. We seek new concepts with the potential toadvance microelectronics, photonics, mechanical actuation,and sensing capabilities. A specific focus area within theMicrodevices thrust is on concepts that couple functional

materials, nanotechnology, and microscale fabrication todevelop revolutionary new microsystem architectures andfunctions. An example of a success is our investments instrained-layer superlattice devices, and new materials-basedcomponents have led to the creation of new laser devicescomposed of indium gallium arsenide nitride. In addition, weare beginning to research silicon-on-insulator (SOI)–basedmicroelectromechanical systems (MEMS) devices.
Often, the results of our E&P research have had multipleapplications. As an example, we originally developedchemiresistor technology for weapons’ applications. Recently,we explored the use of this technology to examine subsurfacewater quality. In addition, chemiresistor technology wasintegrated into the world’s smallest autonomous robot toenable onboard chemical sensing. These microrobots areuseful for mobile, distributed sensing applications and can gowhere human beings either cannot or do not want to go.
Another example of LDRD innovation that has multiplepotential applications is our research in optical switchingMEMS devices. Microoptical switches have exciting potentialin commercial communications applications as well as forvarious applications aligned with the Labs’ business areas.Optical switches are an enabling element for future opticallycontrolled synthetic-aperture radars as well as for nanosatellitecommunications.
Sandia’s LDRD Program provides the opportunity to fundthe initial research efforts in a number of promisingtechnology areas. The results of the research have producednumerous electronics device and system concepts and havesupported a number of applications consistent with the Labs’business areas. These research investments are helping usdevelop our microsystems capabilities to address the criticalnational security issues of the twenty-first century.

An Overview of the Engineering SciencesInvestment Area
Thomas C. BickelDirector, Engineering Sciences CenterSandia National LaboratoriesSandia National Laboratories FY 2002 LDRD Program ReviewJuly 13, 2001
I want to provide a threefold introduction to Sandia’sEngineering Sciences Research Foundation (ESRF) efforts byway of a philosophical overview, a description for the researchportfolio (which includes an external review process), and aperspective for what research activities we envision for thefuture. The ESRF efforts are guided by research plans acrossmultiple technical disciplines. An important aspect ofaddressing the goals of these plans is cooperation with otherorganizations, both internal to and external to Sandia. It hasbeen our experience that the increase in funding in othertechnical areas, especially the health sciences, has led to arapid decline in the interest of graduate students to work in thephysical sciences. As a result, collaborations with the NationalScience Foundation (NSF) and other organizations havehelped maintain our conduit of highly skilled and motivatedyoung scientists and engineers.
Engineering Sciences is one of Sandia’s core competenciesthat provide critical technical underpinnings to support ourmissions. The ESRF research activities are conducted throughtwo programs: the Engineering Sciences (ES) LDRDinvestment area (IA) research explorations, and the DOEDefense Programs (DP) technology base work. A fundamentaldifference between these two activities is the time scale foruseful adoption of the research results. The LDRDinvestments address more fundamental research efforts thathave the potential to produce results applicable to productdevelopment within a three- to five-year timeframe. TheLDRD results roll into the more focused work of the DP techbase efforts and are ultimately incorporated into ourmissions’ base.
The Engineering Sciences LDRD investment thrustsinclude (1) advances in scientific theory, (2) advances inmaterial/constitutive models, (3) advances in numericalalgorithms and methods, (4) explorations in experimentaldiscovery, and (5) experimental diagnostics development. Asexamples of emphasis for these thrusts: in the novel numerical

algorithmic thrust, we are exploring large-deformation solid-fluid interactions via a level-set approach and structuralsimulations using multiresolution material models. In ouradvancing diagnostics techniques thrust, we are investigatingfiltered Rayleigh-scattering diagnostics for multiparameterthermal/fluids measurements.
We have had fifty years to understand continuumengineering mechanics and science. In FY 2002 and in thefuture, ES LDRD investments will concentrate on newinvestigations at the micro- and nanoscales to address the areaof noncontinuum mechanics. These investigations will drawon past research results and understanding but will now beextended by fundamental discoveries to the micro- andmesoscales. Past knowledge will be coupled with newknowledge to support our mission space. For example, we stillseek to better understand what fire is (i.e., a multimeterphenomenon), but we will now also seek to understand itdown to the microscale.
New starts for FY 2002 ES investments will also includeinvestigations into creating high-fidelity friction models forMEMS (microelectromechanical systems). We will examinethe broad concept of how stiction in MEMS devices affectsperformance. We will also develop microscale models toimprove prediction of thermal transport across open or slightlyopen joints in MEMS devices. This research will have animportant impact on the future deployment of MEMS devicesin a number of mission-related areas.
One ES research success that is having an impact on aLabs mission area is illustrated by an example addressing theneed for protecting weapons in a fire. To be able to understandan abnormal environment (e.g., fire), we have to understandthe fundamentals of the environment. In a recent LDRDresearch effort, we investigated a number of novel diagnostictechniques that had the potential to address the radiosity ofsoot development in a fire scenario. We transitioned onediscovery of this LDRD effort, a bench-scale laser-basedtechnique, into a DOE Defense Program research effort thatwas eventually used in an actual JP4 jet-fuel fire scenario. Thefundamental technique originally developed in LDRD hasbeen further refined and incorporated into the MAVEN(Model Accreditation Via Experimental Sciences for NuclearWeapons) Program to address data validation applications.
It is important to emphasize that the ESRF managementteam is managing ES research and development throughoutthe entire R&D spectrum. We annually present the R-D-A

Weearned excellent grades from the panel in the most recentreview of our ES research and Accelerated StrategicComputing Initiative (ASCI) programmatic efforts. In thefuture, we plan to host panels every six months and toalternate between the ASCI and ESRF topics.
One of the principle challenges we face with ES researchis to keep pace with the tremendous advances that are beingmade in computational speed. Faster computational hardwareis outstripping our fundamental understanding of the ES. AtSandia, we are now producing simulations of between 50 and100 million three-dimensional high-fidelity finite elements. Toput that in perspective, ten years ago we were doing two-dimensional simulations on 10,000 finite elements. As we goforward, the very fundamental underpinnings of our mission-related systems (e.g., numerical algorithms, phenomenologicalscience) are being investigated and expanded by Sandia’sLDRD research efforts.

An Overview of the Materials Science & Technology(MS&T) Investment Area
Julia PhillipsDirector, Physical and Chemical Sciences CenterSandia National LaboratoriesSandia National Laboratories FY 2002 LDRD Program ReviewJuly 12, 2001
Due in large part to the impressive advances made intechniques and technology since 1990, the future is verybright for materials science and technology—at Sandia, theLDRD Program has had a lot to do with those advances. Asexamples, the sensitivity of analytical tools (in terms ofresolution and the size of signal) has increased by a factor of103. Computational power has increased by 106 and enablesus to address materials problems that we could not approachbefore. That is why some of Sandia’s most exciting LDRDprojects are in the materials modeling and simulation areas.
The Materials Science & Technology (MS&T) investmentarea (IA) of Sandia’s LDRD Program prioritizes research bythree core thrusts, including
• Aging and reliability of materials• Materials processing• Scientifically tailored materials.Two additional crosscutting research themes have become
increasingly important in the last few years, includingnanoscale science and technology (S&T) for microsystems,and materials and process modeling.
The objective of the materials aging and reliabilityresearch thrust is to advance our capabilities for predictingmaterials properties as a function of time and operatingconditions. Predicting materials properties, in turn, helps us toexamine the future performance and reliability of high-consequence components and systems. Essential to thisunderstanding are our investigations of bulk materialsdegradation, information extraction and analysis, andadvanced analytical technique development. Similarly, weseek advances in understanding surface and interface science,the science of localized corrosion, and nanotribology. Further,investigations in materials performance, interface reliability,and materials aging improve our materials modelingcapabilities.

The objective of the materials processing research thrust isto improve the characterization and modeling of materialsprocessing across all relevant length scales with the ultimategoal of process control, optimization, and true process-basedquality. Processes of research interest include liquid metalprocessing, joining, thermal and cold spray, ceramics, andpolymeric encapsulation. Process innovation supports ourcapabilities for modeling ceramics, welding, andsolidification.
Our objectives in scientifically tailored materials researchinclude drawing upon our scientific expertise to developmaterials with unique properties that may be tailored for abroad range of applications. These research investments arehigh risk and high payoff and are generally focused onfundamental areas beyond current programmatic needs. Forexample, we are investigating the aging and reliability forMEMS lubricants, reactive wetting in solders and brazes, andcopper segregation and aluminum grain boundaries and theinteraction between grain boundaries and dislocations.
The crosscutting nano- and microscale research themesaddress
• Design principles for nanoscale assembly, • Nano- and microscale materials and processes for
microsystems, and • Nanoscale diagnostics.
Design principles for nanoscale assembly has the goalof understanding new nanoscale assembly principles to enablesynthesis and processing of functional nanomaterials withunique structures and revolutionary performanceenhancements over existing materials. We are investigatingmaterials of different functionalities (e.g., photochromic,switchable surface properties) as well as new approaches tonanoscale assembly—particularly, colloidal systems andtemplating. In addition, we are looking at fundamental issues,such as the structure of water near surfaces.
Our goal in nano-and microscale materials and processesresearch is to develop scientific understanding of novel classesof materials, structures, and processing techniques as enablersfor microsystems. For example, we are studying amorphousdiamonds, LIGA (the German term Lithographie,Galvanoformung, und Abformung, for lithography,electroforming, and molding) processing, and low-temperaturecofired ceramic packaging. In addition, we are investigating

the aging and reliability of materials in microsystems and howthese materials behave when they are dormant for years ordecades.
In our nanoscale diagnostics research, our goal is todevelop and apply diagnostic tools for measuring physical,chemical, structural, and biological properties of materials andmaterial systems at the nanoscale.
Overall, the MS&T research investment themes improvethe capabilities required to support the missions of Sandia andthe DOE NNSA (National Nuclear Security Administration).For example, the aging and reliability investigations developour capabilities to support war reserve (WR) surveillance;materials processing research activities expand our tech baseto support WR production and design efforts; andscientifically tailored materials increase our capabilities tosupport WR design. The crosscuts of nanoscale and materialsand process modeling research develop the S&T baseexploited by MESA (Microsystems and Engineering SciencesApplications) and ASCI (Accelerated Strategic ComputingInitiative) applications.
In addition to DOE NNSA, MS&T research also developsour materials technical base to support a variety of DOEmissions, including (among others):
• Aging research supports the Office of Power Technology investigations.
• Materials processing supports the Office of Industrial Technology explorations.
• Scientifically tailored materials expand our capabilitiesto address the Offices of Science (particularly Basic Energy Sciences [BES]) and Transportation Technologies investigations.

Advanced Concepts
The “Understanding andManaging Threats to the SocialFabric of the United States” projectexamines a subtle form of terrorismbased on creating an acute, undesir-able sentiment among major seg-ments of U.S. citizens. This type ofterrorism has the potential to haveprofound effects and could essen-tially cause the United States to beunable to provide for the commongood of its citizens. The project willdevelop an understanding of themeaning of undermining the socialfabric of our society, the potentialthreats, the warning signals, and theviable countermeasures. A panel of
experts discussed terrorist groupsand identified the motivations, goals,likelihood of conflict, and timeframefor executing an event. A simulationmodel was developed during themeeting, capturing the essence ofthe various panelists’ discussions,arguments, and counterarguments.
The Advanced Concepts invest-ment area is looking at how theUnited States might better “wagepeace” by addressing globalresource issues. At first glance, foodproduction and water resources mayappear to be outside Sandia’s scope;however, as world population growsand as global interdependence in-creases, the national security of theUnited States may well depend onreducing conflicts over resources.Sandia has skills and assets that cancontribute technology-based systemsolutions to global resourceproblems.

Solutions to National and Global SecurityIssues Based on Limited FreshwaterResourcesM. E. Tadros, J. E. Miller, D. Y. Sasaki, R. W. Bradshaw
Systems-level solutions are needed to ease freshwatershortages in many regions throughout the world that couldlead to conflicts and increased tension. The Department ofEnergy’s (DOE’s) Environmental Quality R&D Portfolio FY1999–2001 states that one of the three primary areas ofresponsibility of the environmental-quality business line is toprovide the technologies and institutions to solve domestic andinternational environmental problems. Scarce andcontaminated water resources are a major environmentalproblem both in many parts of the U.S. and in areas of theworld that are central to U.S. national security concerns suchas the Middle East, Mexico, and China. The DOE is one of thelead agencies with responsibility to help create and maintainthe scientific and technological infrastructure that supportsthe nation’s security and environmental integrity. This projectis focused on the development of two new methods for waterdesalination: a method for water-evaporation suppressionfrom reservoirs and a method for improving protectedagriculture to reduce water consumption.
We developed a conceptual design for a novel, high-efficiency desalination process that provides process heatbased on distillation by direct-contact heat exchange betweena saline water stream and a nonvolatile liquid. The heat-transfer coefficients for direct-contact boiling are much largerthan comparable tube-wall heat-transfer coefficients. Thismethod enables the dissolved solids in the saline water sourceto be collected by the working fluid, preventing the dischargeof a concentrated brine stream. Since the cost of the sweepinggas alone is enough to make the economics questionable, werecommend that future work in this area focus on vacuum operation.
We carried out controlled experiments with two tomatoplants grown in a conventional glass greenhouse and agreenhouse treated with the infrared reflective film, andcollected data on the crop yield, energy consumption,temperature, humidity, and water consumption. The results are

very encouraging and support our design concept. Wesubmitted a technology advancement disclosure.
We carried out laboratory and field (i.e., swimmingpool) experiments to develop new surfactant composition forsuppression of the evaporation of water. We found a mixtureof fatty alcohols of various chain lengths to be superior to amixture reported by others, particularly under conditions ofwind and wave action. The new monolayer films exhibitedhigh surface pressures, film recovery, and self-healingcharacteristics.
We analyzed the impact of technologies supportingsustainable development for the border region between theUnited States and Mexico. We evaluated and improved upon asolar water-distiller/water-purification technology and an earlywarning system for infectious disease outbreaks.

Understanding and Managing Threats to theSocial Fabric of the United StatesJ. Espinoza, J. G. Turnley, T. D. Moy
Terrorism is the use of force or violence againstpersons or property in violation of the criminal laws of theU.S. for purposes of intimidation, coercion, or ransom. Oneway governments attempt to reduce our vulnerability toterrorist incidents is by increasing security at airports andother public facilities. However, little attention seems to begiven to a more subtle, yet potentially far more consequential,form of terrorism than bombing facilities and airlines—a formof terrorism based on creating an acute invidious sentimentamong major segments of the citizenry of the United States.This has the potential to have far-reaching, profound effectsand, if properly orchestrated, could essentially cause theUnited States to be unable to provide for the common good ofits citizens.
This project will develop an understanding of themeaning of undermining the social fabric of our society, thepotential threats, the warning signals, and the viablecountermeasures. It should be emphasized that this proposedwork is distinct from, but complementary to, Sandia’s criticalinfrastructures surety activities. The focus will not be on whata malevolent agent might do to our infrastructures, but ratherupon what might be done to cause major segments of thecitizenry of the United States to violently interact with each other.
The innovative features of this work are (1) thesynthesis of an integrated picture of the potential threats toour society as seen from myriad historically disparateperspectives, (2) the development of a dynamic simulation thatcan provide valuable insights into the complex phenomenathat serve as the glue for our social fabric, and (3) theanalysis of urban race riots of the sixties and seventiesprofiled via an artificial neural network (ANN) classifier thatsupports the development of the dynamic model and promotesthe understanding of deliberate and planned attacks to breakdown the social fabric of our nation.

Sandia met several significant milestones in thedevelopment of this project:
• Vital Issues Process II meeting. Sandia hosted apanel discussion in Washington, DC, on 28 February 2001.The panel comprised a mix of national security experts,economists, social scientists, journalists, experts on aspects ofthe U.S. physical and communications infrastructure, andothers aware of and/or sensitive to pressure or weak points inour social fabric, and how those weak points could be or havebeen manipulated. The panel discussed the potential forcomplete social infrastructure breakdown through the use ofasymmetric warfare (IBAW).
The panel was divided into three groups, each ofwhich was tasked with developing scenarios detailing theinfrastructure breakdown of the United States according to thefollowing categories:
(1) Identification of infrastructure vulnerabilities(2) Development of scenarios for attacking
vulnerabilities(3) Presentation of the scenarios(4) Critique of the scenarios in terms of feasibility and
likelihood.We produced a textual report documenting the
discussions and outcomes of the VIP II meeting andsummarizing the discussion, the themes that arose, and theIBAW scenarios. In view of the sensitivity of the issues, thereport of the panel discussion is currently not available forpublic release or distribution.
We also developed a dynamic model in real time thatreflected the panel discussion. PowerSim Constructor, asimulation model, was developed during the meeting tocapture the gist of the various panelists’ discussions,arguments, and counterarguments. We have since updated themodel and modified it to properly reflect the outcome of theVIP II meeting.
• Urban riot computer model (ANN classifier andpredictor). We are developing an urban riot computer modelas a tool for policy- and decision-makers to assist them inidentifying conditions that have historically been conducive tourban rioting. The software model will use socioeconomic,environmental, and public opinion conditions to classify thelikely severity of an impending riot, thereby helping decision-makers countermand or prevent riots in their communities.The Advanced Concepts Group based the development of theriot-prevention computer model on an analysis of historical

data from the 500-plus race riots of the sixties and seventies.The Kerner Commission, established by President Johnsonafter a summer of violence and destruction in American cities,conducted the most thorough and reliable study of the 1960surban rioting to date. We relied heavily on the findings of theCommission, which were published in April 1968 as “TheReport of the National Advisory Commission on CivilDisorders.” The relevant riot pa
