A need exists for inexpensive, disposable, broadcast capable chemical / explosive-compound sensors that also provide site weather conditions. The state-of-the-art does not meet the need described both in terms of CWA sensor cost/size and lack of a low-cost deployment system. ADA proposes under this three-phased SBIR program to develop a system comprised of a suite of covert, modular, lightweight ...

Direct Energy Solutions proposes to design, fabricate and test a basic prototype decontamination device for building protection from chemical and biological weapons attack and the general enhancement of indoor air quality. The decontamination device generates metastable Singlet Delta Oxygen (SDO), O2 (a1¿), a strong oxidant of biological and chemical pathogens, from direct optical excitation of ...

This SBIR Phase II proposal addresses development of a field-portable, amperometric biosensor for monitoring organophosphorus (OP) and carbamate insecticides in water. The miniaturized biosensor will use a modified screen-printed microelectrode with high sensitivity and lowlimit of detection for OP and carbamate pesticides. This biosensor will be selective for OPs and carbamates. The enzyme use ...

Polychlorinated biphenyls (PCBs) remain a significant environmental threat even though manufacturing of PCBs was discontinued 30 years ago. PCBs are toxic amd suspected to carcinogenic to humans and are therefore carefully monitored. Due to the chemical and thermal stability of PCBs in the environment and the continued use of rtansformers containing these chemicals, very specific regulations are ...

Current methods of transmitting low-frequency RF energy from airborne platforms involve antennas such as blades that are electrically inefficient and a place a large aerodynamic burden on the airframe. SOCOM desires a method of efficiently transmitting low-frequency energy (VHF-UHF) at high power levels from airborne platforms. The desired gain numbers (-2 to 0 dB) at these frequencies would requi ...

The contamination of drinking, recreational, and agricultural water sources in developed and/or developing countries, including the United States, necessitate a fast, reliable detection method. The use of biological weapons by terrorists to contaminate water supplies is a more recent development that poses additional challenges since such agents are difficult to observe at the time of initial dep ...

The single most effective method to thwart security threats posed by people with hostile intent is to detect their presence early. Unfortunately, large scale standoff detection of humans is difficult. Various sensors, including still and video cameras, have been designed and applied to human detection, however, to date a person is required to be in the detection loop since robust, automated detect ...

Finite supplies of increasingly dirty petroleum, climate changes due to carbon dioxide emissions and communities choking in pollution caused by manufacturing as well as their own solid wastes are pressing environmental problems. Because of these problems, sustainability is becoming a leading issue in the plastics industries - disposal options are increasingly limited in major markets such as Cali ...

TDA Research, Inc., (TDA) is developing a novel non-carbon sorbent to control mercury emissions from flue gas from hazardous waste incinerators and coal-fired power plants. The sorbent could be easily injected into the flue gas and could be recovered in the Particulate Control Device (PCD) along with the fly ash, minimizing capital investment. Unlike the carbon materials used to date, our sorben ...

Conventionally, deep desulfurization in a refinery is accomplished by a multi-step process including, hydrodesulfurization (HDS) over CoMo/Al203 and NiMo/AL203 catalysts and subsequent removal of the H2S. However, the HDS process is not suited well to produce ultra clean (essentially sulfur free) transportation fuels. At he severe reaction conditions required for deep desulfurization, the olefin ...
