Abstract

Nanomaterials have been shown to effectively protect stainless steels from high temperature degradation. However, recently we discovered the unique antioxidant properties of the same rare earth nanoparticles, where it protects mammalian cells against damage caused by increased reactive oxygen or nitrogen species, and has been shown to act as effective superoxide dismutase mimetic in vitro. The redox ability of rare earth oxides has been used in a wide range of applications such as three way catalysis, oxygen buffer systems, sensors and corrosion prevention. This presentation will provide a brief overview of the applications of these nanostructures in treatment of disorders caused by reactive oxygen species. I will also describe how I took this journey from my undergraduate research till now. I will end the talk by discussing pathways to transform research to technology commercialization.

SJSU Materials Student Poster Abstracts

Project: Development of Natural Fiber Reinforced Composite for Sports Equipment Members: Chua, Justin; Thompsen, Ryan; Montecillo, Matthew Advisor: Chung, Richard (Ph.D0 Abstract: This project is intended to develop a biodegradable, natural fiber composite material to replace the 313-825,000 kg/yr of waste generated by the disposal of conventional composites used for the fabrication of tennis rackets. Experimentation was conducted on the use of sisal fibers in this application as well as a study on the possible extraction of nanocellulose fibers from sisal stock. PLA/fiber composites were then fabricated and subjected to standard material testing and characterization to gage their merit for use in sports equipment such as tennis rackets.

Project: Thermal Cooling of Bone Drills through Additive Manufacturing Members: Crill, Teralyn; Murray, Garret; Phillip, Stauffer; Advisors: Benz, Ross; Erogbogbo, Folarin (Ph.D) Abstract: Drilling of bone is used for a variety of surgeries to repair, replace and remove bone from a patient. When placing a fixture into a patient’s bone to secure the area, a surgical drill is used to predrill a hole before inserting the fixture. When drilling the hole, surgeons must be careful not to increase the temperature of the patient’s bone to reduce the likelihood of osteonecrosis. Osteonecrosis frequently occurs due to high drill bit temperatures in operations associated with the fixture of tibia and femur bones. Here we will show how advanced manufacturing technologies can allow internal cooling channels to be dispersed through the center of the drill. This may allow a significant decrease in the drill bit operating temperature and allow for patient bone temperatures to be reduced during drilling to reduce osteonecrosis likelihood. The occurrence of osteonecrosis can require many more resources to be directed toward the patient to reduce the damaging effects of osteonecrosis. Such improvements can reduce the need for unnecessary follow-up surgeries, decrease patient hospital stay, and healthcare cost.

Project: Design and Fabrication of MIS Solar Cells Members: Justin, Mark; Advisor: Parent, David (Ph.D) Abstract: A process for development of metal-inulsator semiconductor (MIS) solar cells has been developed at SJSU. A series of fabrication parameters, techniques, and materials has been evaluated for use in this process. Until now, most solar cell development at SJSU has been based on p-n junction solar cell fabrication methodologies which are labor intensive and prone to defects in an “educational” environment.

Project: Processing 3D Molds for Centrifugal Droplet Generation Member: Rahim, Syed Advisor: Bousse, Luc; Rosenfeld, Liat (Ph.D); Simon, Melinda (Ph.D); Abstract: Microfluidic devices have great potential in chemical, aerospace, and healthcare industries. Two successful commercial application of these devices are the inkjet print head and the pregnancy test. Photolithography with Soft lithography, and milling are two methods of fabrication for microfluidic devices. An alternative method to create microfluidic devices can be achieved through additive manufacturing of cost effective molds. Variability in the printed molds is an issue that this project aims to address through surface treatment with acetone vapor and polishing. Although not as precise as the mentioned methods, additively manufacturing a mold can significantly reduce the barrier to entry for further research and new applications. Preliminary results show similarity between a additively manufacture mold and channel dimensions of a casted polydimethylsiloxane (PDMS)

Project: Development of a Zirconia Synthesis Method with Incorporate Graphene Quantum Dots Member: Fok, Daniel Advisor: Keles, Ozgur (Ph.D) Abstract: As we move toward the future energy storage will become an even more important topic than it is today. Energy storage technologies such as batteries are extremely useful but have disadvantages. Disadvantages such as long charging times and relatively low number of charge/discharge cycles make technologies such as supercapacitors very attractive. However even supercapacitors have disadvantages although some of those disadvantages are not inherent to the technology itself but the materials used to make the device. This project was on the development of a material that can help alleviate some of the issues that supercapacitors have. The process for the material being developed was zirconia with graphene quantum dots (GQDs) imbedded in the particles. This material based off of the research of others could prove to promising for the development of new supercapacitors.

Project: Analysis of Biosynthesized Silver Nanoparticles Member: Baldwin, John; Advisor: Peters, Christina Abstract: Nanoparticle production is typically a toxic and complex process. Synthesis through plants however offers a cheap, clean, and scalable alternative. This experiment will compare biosynthesized silver nanoparticles to traditionally produced particles for high performance industries to establish similarities. Three plants being tested are Zingiber Officinale, or ginger, Vitis Vinfera, a species of wine grape, and Ocimum basilicum, or sweet basil. All these plants contain an extract which reduce silver nitrate to form the desired silver nanoparticles. The main problem addressed is mass producing nanoparticles while limiting cost and effect on the environment. This study will focus on the characterization, i.e. size distribution, morphology, impurities, and crystallinity of silver nanoparticles synthesized from plant extract. The results will point to which components in each plant extract produce which beneficial qualities of nanoparticles such as lowest impurity amount, toxicity of impurities, and average size of particles. These properties are important for application in engineering materials as toxic functional groups prohibit use in the medical industry, while impurities and non-crystalline particles can't be used in the semiconductor or nanotech industry. This research seeks help accessibility and safety of nanotechnology by showing the feasibility of utilizing an economic and green process of producing silver nanoparticles.
