The use of enzyme-linked immunosorbent assay (ELISA) to detect contaminants such as solvents, fuels, and pesticides in soil and water samples is now well established. Although ELISA and related methods can facilitate analysis of samples, several washing and separation steps are involved that require 30 to 120 minutes per sample to reach equilibrium. Recently, near infrared fluorescence immunoassa ...

Major improvements in process control, compliance monitoring, and objective environmental decisionmaking could be made if accurate, rugged, and affordable sensors were available. Of particular interest are environmental sensors that can continuously and quantitatively determine both toxic metal vapor emissions and organic compound emissions from complex matrix sources such as power plants, incine ...

Inorganic color pigments based on hazardous metals such as chromium, mercury, cobalt, lead, etc., account for more than 95% of the U.S. and worldwide pigments consumption. Color pigments are commonly used by numerous industries and in various consumer products. It is estimated that they are one of the largest vehicles of heavy metal-based chemicals in commerce. A technology that can provide a co ...

Using distributed interactive simulation (DIS) to conduct effective training, analyses, or mission support in a tactical nuclear weapons effects (NWE) environment requires realistic computer generated forces (CGF) that are sensitive to such effects. This level of sensitivity requires CGF to apply valid and reliable speed-accuracy measures of environmental effects on human performance within the D ...

Pulsed power systems for electric armament and compact weapons require increasingly smaller energy delivery systems and higher levels of reliability and component safety. Although new capacitor technologies such as double layer and electrostatic supercapacitors promise energy densities higher than 10J/cc, liquid impregnated film dielectrics with energy densities of 2.5J/cc, continue to be the sta ...

Survival of present day microelectronic circuits depends on their protection from self generated and external electromagnetic interference. This proposal is oriented toward the class of interference generally referred to as overvoltage transients. Means for mitigating these transients include gas discharge tubes, and various solid state devices. Each of these has their own advantages in particu ...

We propose to design a compact, multiple purpose electromagnetic sensor for monitoring the extremely low frequency (ELF), very low frequency (VLF), and low frequency (LF) spectrum. Our goal is to design a modular, low cost sensor capable of being configured for multiple applications and capable of being employed in remote, unattended sensor networks. We describe three applications or scenarios t ...
