ULTRA- HIGH TEMPERATURE CERMAICS: PUSHING THE BOUNDARIES OF ENERGY AND AEROSPACE MATERIALS

NOVEL NANOSTRUCTURED MATERIALS FOR SOLAR PHOTOVOLTAICS

PLASMONIC THZ TECHNOLOGY: A NEW CLASS OF DETECTORS

New research, led by Dr. Daniela Radu, aims to develop nanostructured materials, and more recently 2D nanostructures. The novel material is fabricated in their laboratory and designed for solution-processed solar photovoltaics; optoelectronic applications (including superconducting materials); and laser components, and sensors featuring polymeric encapsulated 2D materials.

Dr. Zhe Cheng’s group is developing a new class of high temperature ceramic powders, including nanopowders for multi- metal element ceramic materials. The materials are synthesized and processed using various methods. The materials are studied for their microstructure and chemical/physical properties. The new materials might find applications from aerospace and defense to energy and electronics.

Terahertz technologies utilize electromagnetic radiation in the frequency range between 300 GHz and 10 THz. Potential applications for terahertz technology in biology, chemistry, medicine, astronomy and security are wide ranging. In Dr. Pala’s INSYST laboratory, they develop graphene-based plasmonic THz detectors. The key advantages of such detectors are tunability, a relatively low value of the noise equivalent power and a potential to detect signals with very high frequencies (up to hundreds of GHz).

FLEXIBLE WOUND MONITORING SENSOR

LITHIUM-ION CAPACITORS: TOWARDS HIGH PERFORMANCE CAPACITIVE ENERGY STORAGE

NEW GRAPHENE BASED TECHNOLOGY TO DEICE AIRCRAFT

Dr. Bhansali’s team is currently developing a portable wound monitoring sensor that can track progress of wound healing in real time. The novelty aspect lies in the sensor, which is printed in flexible material like cloth and can be used as an integrated component of wound dressing.

Energy storage devices are important power supply units for various electronic systems. The key performance output desirable in energy storage devices include high energy density, high power density and good cyclability.

Lithium-ion capacitors (LICs) represent an attractive energy storage concept with a promising potential to provide a good combination of these performance properties. This research work led by Dr. Chunlei Wang requires the design, fabrication and evaluation of high performance macroscale and microscale LICs which could serve as power supply units for existing and next generation electronic systems

Adhesion of ice to the surfaces of aircraft in severe cold weather compromises aircraft aerodynamic performance. Airport deicing operations are performed for safety, causing extensive flight delays for travelers and a heavy financial burden for the airline industry. Dr. Arvind Agarwal’s team has developed a graphene foam−polymer composite with superior deicing efficiency and strength. The graphene-foam polymer composite provides lightweight coatings and free-standing components with heating abilities, with exceptional thermal stability. The graphene reinforcement also increases the tensile strength of the polymer coating on the aircraft and reduces the impact of toxic chemical runoff seeping into the ground and water.

The interdigitated micro fingers, successfully fabricated and tested in AMERI as shown, are used for lactic acid detection in many applications including clinical care, sport medicine, and food processing.

Novel experimental approaches are being developed by Dr. Sarah Du’s team at FAU for the study of cell biophysics. The integration of cell culture, biosensing, and microfluidics technologies provides new opportunities to measure cellular behavior and responses to various stimuli in real time and in a quantitative manner, under the in vivo-like cellular microenvironment.The applications of these microfluidic chips include but are not limited to: (a) placenta-on-a-chip model for the study of placental malaria, (b) smart biosensor for diagnosis of sickle cell disease, and (c) accelerated life testing of red blood cells. Part of Dr. Sarah’s research is carried out in AMERI.

A research project in the bioelectronic and electronic packaging laboratory led by Dr. Raj Pulugurtha is pioneering new technology advances for wearable and implantable electronics with wireless communication and power converter building blocks. Fine-pitch deformable interconnection technologies between devices, substrates and electrode arrays are developed for seamless power and data between electronics and biological interfaces. The team has demonstrated deformable interconnects between flexible carriers and devices by utilizing elastomeric adhesives and underfills.
