With significant strides being made on wide bandgap (WBG) semiconductor devices for high-power electronics, there is a concurrent need for packaging encapsulants with reliable long-term performance in a more rigorous operational environment. The WBG power devices are set to be fielded in electric vehicles, aircrafts, spacecrafts, and energy producing systems where working conditions can see temper ...

Vertical Photoconductive Semiconductor Switches can be designed to support numerous filaments that simultaneously conduct current. A two dimensional array of current channels can be lithographically patterned on the surface of a substrate to achieve significant power scaling. One of the challenged is coupling the optical trigger signal efficiently into the filament apertures. Nanohmics will desig ...

Defense MicroElectronics Activity (DMEA) seeks to develop a robust technique to sample and read DNA taggants applied to surfaces of microelectronics supply chain components that employs machine learning methods to develop trained models capable of detecting counterfeit microelectronic parts with > 95% accuracy. To address the need for rapid (< 5 minute) genetic taggant signature profiling rooted i ...

Refrigerants are known to have harmful impacts on the environment. It is essential that those that are particularly harmful with a high global warming potential (GWP) are recovered correctly for proper recycling or disposal. Unfortunately, all too often, refrigerant is not properly recovered either due to system failure, technician error, or unincentivized industry practice. With implementation of ...

This Small Business Innovation Research (SBIR) Phase II project will perform some needed tests for commercialization of the highly PFAS-selective nanofiber mats fabricated from electrospun polymer nanofibers. The Phase I results have shown the proof of concept for two materials developed for the removal of PFOA and PFOS with over 91% efficiency at very high concentrations (ppm level) and 99% at lo ...

We propose to lay the groundwork for the implementation of a completely integrated SiC BiCMOS/LDMOS technology for integrated control/power circuit applications reliable for operation up to 300 C. Our workplan to accomplish this goal comprises improving device speed and reliability by device engineering, establishing baseline reliability and qualification tests to support and certify development, ...

Fats, oils and greases (FOGs) cause 75% of sewer systems in the US to operate at 50% capacity, cost US cities over $20 billion in sewer maintenance, and cause over 40,000 sewer overflows annually. Most commercial kitchens are required by law to remove FOGs with a grease interceptor from wastewater before emitting into public sewers. In order to reduce sewer maintenance costs and overflows while in ...

The proposed device is a compact, portable, and robust battery-powered analytical instrument for monitoring of ultra-low concentrations of various VOCs in complex backgrounds. Our technology is based on principles of analytical gas chromatography (GC), utilizes scrubbed ambient air as carrier gas and a novel highly integrated multisensory platform as a detector. Due to the implementation of a mult ...

DMEA seeks to develop a robust technique to read DNA taggants from labeled electronic components to protect the electronic supply chain from counterfeiting. To address this need, Nanohmics Inc. proposes to develop an on-chip Sanger-based ion mobility sequencing technology (eSIM) with novel direct electrical read-out of the DNA sequence information. Specifically, the method involves incorporation o ...

The aging supply chain management is the available long term protection against IC counterfeiting. For better protection, there is an urgent need for an advanced counterfeit detection system. The industry has made progress in cataloging the features in counterfeit parts and the physical tools to detect them. However, the methods still largely depend on human skills which are time consuming and oft ...
