Reliable and sensitive detection of biowarfare agents (BWAs) such as Bacillus anthracis, Yersinia pestis, Francisella tularensis, ricin, botulinum toxin, etc. is an important challenge for both military operations and domestic anti-terrorism efforts. We are proposing to develop a biomimetic polymer coating, containing receptors for BWA targets, that becomes fluorescent when exposed to samples con ...

This goal is to construct a low-cost, polymeric, nanomaterial-based assay for the detection of multiple biological agents in a single device using our nanomanipulation technology to meet or exceed the sensitivity of the current two-line assays used in DoD applications. The nanodevice will exhibit no background streaking, cross bleeding, or other flow problems often associated with laminar flow de ...

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 ...

The Bush Administration recently proposed a 90 percent reduction of air pollution emissions from off-road diesel equipment. The Administration indicated that diesel emissions are responsible for large amounts of particulate and NOx emissions from off-road construction, farm, mining, and locomotive and marine engines. A primary approach used to reduce NOx emissions is exhaust gas recirculation (E ...

A nearly universal trend in modern technology is integrating systems, and their associated devices, on decreasingly smaller scales. Examples range from complete telecommunication systems on a chip to implantable medical devices smaller than human cells. The majority of these devices apply hybrid designs that integrate on a commensurate scale electronics with active and passive optical components. ...
