In December 2000, EPA announced its intent to regulate the emission of mercury from coal-fired power plants. ADA Technologies, Inc., is developing a family of new disposable sorbents for this application. The sorbents consist of a natural silicate doped with chemicals to capture and immobilize vapor-phase mercury and mercury compounds. Laboratory testing in Phase I has shown the new materials to h ...

Mercury from combustion sources is a major concern to the nation's air quality. In December 2000, EPA announced that it would regulate mercury emissions from coal-fired boilers under Title III of the Clean Air Act Amendments of 1990. EPA plans to issue final regulations by December 2004, and is expected to require compliance by December 2007. The Department of Energy estimates that control of merc ...

Recently, there has been more emphasis on a system-on-a-chip (SOC) to integrate logic, analog functions, volatile and non-volatile memory onto a single chip. In order to overcome limitations of conventional floating gate non-volatile memory devices, we areproposing the non-volatile memory elements based on silicon nanocrystals. The silicon nanocrystals will be fabricated in the gate oxide of the c ...

This Small Business Innovation Research Phase I project proposes the development of novel materials to be used in a ferroelectric FET (Field Effect Transistor) memory cell. The proposed memory cell is non-volatile utilizing a non-destructive readout,single transistor design. As a result it has unlimited endurance, very small cell size and fast read and write. The most important properties to be ...

A recent workshop on wide bandgap semiconductors concluded there is still an urgent need for a GaN single crystal boule. Such a boule would allow the fabrication of single crystal wafers of high quality GaN for the epitaxial growth of high qualitydevices and integrated circuits for numerous applications from short wavelength lasers, high performance transistors to UV/XRay detectors. Astralux, ...

Electrochemical systems for pulsed power and high continuous power levels face a critical optimization problem. One must spread reagents in extremely thin layers to provide maximum surface area for reaction sites that release energy. This increases powerper unit mass of reagent (specific power). One must also provide low-resistance current paths from every reaction site to the end load, so that ...
