Significant deficiencies exist in the laser source technology for IRCM, specifically in the limited pulse rep-rate capability, limited average power output and capability to be transitioned to military environments. We propose a novel tandem OPO concept that uses two noncritical phasematched OPO's in KTA and AgGaSe(2) to generate the desired three output wavelength bands simultaneously. This con ...

Automobile three-way catalyst (TWC) are quite efficient at steady state operatingtemperature typically destroying 98% of incoming hydrocarbons (HCs) and carbonmonoxide (CO). However, up to 80% of emissions occur during the first fewminutes of Federal Test Procedure when the engine is running rich, the engine iscold and TWC has not reached light-off temperature. To significantly reduce HCsand CO ...

Ozone treatment of wastewater to destroy organic contaminants prior to discharge into the environment is an extremely effective advanced oxidation technology. To date the use of this powerful technology has been limited in part by the relatively high capital costs of an efficient ozone to water, gas-liquid, mass transfer system. Existing ozone injection devices must overcome the inherently low m ...

Lean burn spark engines are a promising technique to further reduce both NOx and hydrocarbon/carbon monoxide (HC/CO) engine emissions. Higher lean burn levels improve HC/CO oxidation while simultaneously reducing NOx formation. The NOx reduction is due to cooler flame temperatures. While the lean burn limit (beyond which combustion is poor) restricts further emission reductions, the use of oxyg ...

This Phase I project involves the development of a portable system for the analysis of trace metals in aqueous solutions based on an innovative disposable multi-element nanoband electrode sensor. The system will be capable of real-time detection of a variety of heavy metals in aqueous solutions, including Zn, Cd, Pb, Cr, Cu, and Hg with a 100 ppb detection limit. The system also will be capable ...

The wavelet transform has generated excitement among researchers from a wide range of disciplines. Wavelets have an extremely rich mathematical foundation and have been proven valuable for a variety of applications. New ideas are being pursued at a breathtaking pace leading to innovative algorithms. The challenge before us now is to identify and harness these ideas and develop a coherent set of ...

Using new low bandgap GaSb photovoltaic cells, JX Crystals has recently demonstrated functional thermophotovoltaic prototype generators. While it is generally believed that the cost of materials makes non-silicon photovoltaic cells prohibitively expensive unless one can develop thin film cells, this thesis is wrong for thermophotovoltaic cells. Specifically for the GaSb cell, the Ga and Sb mater ...
