This article explores the role of shear-thinning, pseudoplastic non-Newtonian fluids in causation fatal accidents involving hazardous atmospheres. Analysis indicates an appreciable likelihood occurrence structures infrastructure. When subjected to a shear force, such as stirring, stored gas emits from these fluids. Depending on gas, lethal concentrations can develop almost instantaneously. Upon...

The development of a low-cost, simple colorimetric sensor array capable of the detection and identification of toxic gases is reported. This technology uses a disposable printed array of porous pigments in which metalloporphyrins and chemically-responsive dyes are immobilized in a porous matrix of organically modified siloxanes (ormosils) and printed on a porous membrane. The printing of the or...

Many questions related to the cellular mechanisms of lung injury/toxicity from highdose exposure to militarily relevant toxic gases, chemicals and/or irritants still remain unanswered. This is primarily due to limited interest in the toxicity of such high-level exposures in the civilian sector. Early detection and delineation of cellular changes following exposure to high-level environmental ox...

Toxic gases, vapors, and particles are emitted from concentrated animal feeding operations (CAFOs) into the general environment. These include ammonia, hydrogen sulfide, carbon dioxide, malodorous vapors, and particles contaminated with a wide range of microorganisms. Little is known about the health risks of exposure to these agents for people living in the surrounding areas. Malodor is one of...

The goal of this study is to characterize the Raman spectra of tungsten trioxide (WO3) at increasing temperatures in the range 30.6–170 ̊C in order to understand the behavior and characteristics of WO3 after adsorption of toxic gases (e.g. NO and SO2) and to provide a database of Raman spectral features for future use in providing an optical complement to semi-conducting metal oxide gas sensor t...
