Connectors for joining aluminum plates
Project ID: D2018-49Background Several approaches have been taken to join aluminum plates or sheets. However, each has disadvantages. For example, resistance spot welding of common alloys can cause expulsion, distortion, short electrode life, and the formation of voids and cracks. Friction stir welding is limited in that it requires equipment to s...
Altering shear thickening in fumed silica suspensions using nanoparticles
Project ID: D2018-58Background Silicon chips can contain over one billion transistors in one square centimeter of surface area. In order to interconnect such a large number of electrical elements, materials must be planarized with nanometer-scale precision while leaving the exposed surface free of defects, such as scratches, gouges, or pits. Chem...
Ocular Ultrasound Training Simulator (OUTS)
Project ID: D2018-28Background The use of ocular ultrasound on emergency patients has recently been adopted by emergency physicians to evaluate for ocular pathology and emergencies. Point of care ultrasound (POCUS) has been found to be highly accurate in diagnosing and evaluating for ocular pathology in patients presenting in emergency department...
Inexpensive, Earth-Abundant, and Tunable Hole Transport Material for CdTe Solar Cells
Project ID: D2017-08Background Photovoltaic (PV) cells have been produced with a wide variety of materials for each functional layer. The typical PV is a substrate layer coated with a semiconductor layer and two ohmic contacts. Thin film solar cells use a thin absorbing layer, such as Cadmium telluride (CdTe). CdTe is the most eco-friendly, high e...
Iron Pyrite Nanocrystal Back Contact for CdTe Solar Cells
Project ID: D2014-32 Background Photovoltaic (PV) cells have been produced with a wide variety of materials for each functional layer. The typical PV is a substrate layer coated with a semiconductor layer and two ohmic contacts. Thin film solar cells use a thin absorbing layer, such as Cadmium telluride (CdTe). CdTe is the most eco-friendly, high ...
High yield production of fuels and petro- or oleo-chemical precursors from vegetables oils/liquid feedstocks in a continuous-flow pyrolysis reactor
Project ID: D2016-39Background Pyrolysis of oil seeds and microalgae has the potential to displace petroleum-derived fuels. Current methods require batch processing which produces low yield of liquid products, contamination from secondary reactions, and causes buildup inside the reactor. Therefore, there is a need to improve the efficiency of pyro...
A Novel Process to Coat Implant Surfaces with Bi-Functional Bioactive Antibacterial Coatings
Project ID: D2017-07Background In the orthopedic field, there is a need for improved capabilities for creating strong osseointegration at bone-implant interfaces and treating bacterial infections. Implant-related infections occur in 0.75% in hip implants and 1.5% in knee implants resulting in reduced lifespan and increased failure rate of prosthes...
Cost- and Energy-Efficient Device for De-watering Microalgae Using Stimuli-Sensitive Hydrogels
Project ID: D2016-01IP Status: US Patent 10,077,422Invention Description: Currently, a major hurdle for commercial-scale production of fuels and other products from microalgae is recovering algal biomass from growth media with minimal cost and energy input. When cultivated in open raceway ponds, microalgae concentrations are very low – typica...
Process to Produce High-strength and Corrosion Resistant Alloy for Patient-Specific Bioresorbable Bone Fixation Implants and Hardware
Project ID: D2016-43IP Status: Provisional Patent Application # 62/270,227Invention Description: Novel metallic alloy composition combined with a post-shaping heat-treatment process produces bioresorbable bone fixation hardware and implants. The technology produces stronger and less biocorrosive patient-specific devices than the base material. The ...
A Bi-level Equalizer for Battery Cell Charge Management
Project ID: D2016-41Invention Description and Novelty: This technology can provide a large increase in the capacity of older lithium ion batteries (LIB) that consist of cells connected in series or series/parallel. These LIBs require a battery management system (BMS) which measures and equalizes (EQU) the cell voltages to maximize performance and p...
