"In this program, we will develop a breakthrough technology that will enable wafer-scale epitaxial lift-off (ELO) of GaN power device heterostructures from low-dislocation-density bulk GaN substrates. This technology will be used to provide a low-cost vertical junction field effect transistors (VJFETs) with high breakdown voltage (greater than 1,200 V) and high current capability (greater than 100 ...

In 2011, there were 60,000 dairy farms in the US. Of there, 56,600 had herds of fewer than 500 animals. Currently, manure digester installations are only considered economical for herds of at least 500 animals. There require turbine or diesel generator sets of 100 Kilowatt size and larger. The need exists for a smaller waste to energy conversion approach for implementation on small farms were ...

This Small Business Innovation Research (SBIR) project will employ Nanofiltration to generate sulfate ion feedstocks and high current density on-site generation (synthesis) of the powerful oxidant peroxodisulphate (“persulfate”) with novel, high reliability boron-doped untrananocrystal-line diamond (UNCD) electrodes to dramatically lower the cost of unconventional fossil fuel (FF) waste water ...

A team of EP Purification and the University of Illinois engineer and chemists is pursuing the commercialization of low cost microchannel plasma modules capable of efficiently producing ozone for water treatment. The conservation of water resources for human consumption is a growing national priority. Contamination of ground municipal water by animal manure, fertilizer and pharmaceuticals, for e ...

Solvents are a valuable processing tool in the chemical and related industries. Solvent are used to enhance mass transfer, heat transfer and in most cases are a processing aid and eventually are not used in the final product but to enhance the fabrication of the final product. While solvents are very valuable, they also cause a significant problem with their volatility and associated emissions.� ...

High performance infrared detectors in the LWIR regime are highly needed in a number of missile defense missions. In order to image targets from long distance, it is important that imagers have high sensitivity and high resolution. This leads to technical goals of having low noise, low dark current in small size pixels in large arrays. While saturated performance levels of traditional systems base ...

The primary objective of Phase I work performed by the team of CU Aerospace and the University of Illinois is to produce a powerful and easy to use, parallel, fluid-dynamic, chemical-kinetic, and optical simulation software package that will function on any modern computational platform (Unix, Linux, Windows, MacOS), be applicable to a wide range of laser systems and other technical problems of in ...

The potential threat of directed energy weapons (DEW) and other high peak power electromagnetic transient signals require radar systems to implement front door protection against high power signals. Fast ultra wideband (UWB) and high power microwave (HPM) signals are not successfully blocked by most current protection technologies. The Phase I work demonstrated a quasi-passive, solid state e ...

Under the work proposed here, we will develop a physics based comprehensive software for modeling the behavior of a diode pumped alkali laser: DPAL. The software will be designed primarily for a He-Rb DPAL. However, it could easily be applied to DPALs based on other alkali atoms, such as Cs. Furthermore, the model would be versatile enough to be applicable to other high energy lasers as well. ...
