  • The Atmospheric Pressure Plasma Jet (APPJ) is a unique, capacitively-coupled rf, nonthermal, uniform discharge operating at atmospheric pressure with a high flow of He/O{sub 2} feedgas. The APPJ generates highly reactive atomic and metastable species of oxygen and directs them onto a contaminated surface at high velocity. This may provide a much needed method of decontamination of CBW agents which, unlike traditional decon methods, is dry and nondestructive to sensitive equipment. The reactive effluent of the APPJ at 175 C has been shown to kill Bacillus globigii spores, a surrogate for Anthrax, with a D value (time to reduce viabilitymore » by a factor of 10) of 4.5 sec at a standoff distance of 0.5 cm. This is 10 times faster than hot gas at the same temperature and requires 80% less energy input to achieve the same level of kill. This D value is also an order of magnitude better than achieved by other nonthermal plasma discharges, and unlike these other discharges, the APPJ provides a downstream process which can be applied to all accessible surfaces with no need for the contaminated object to fit within a chamber. Through active cooling of the electrodes, the authors have also achieved a D value of 15 sec at an effluent temperature of just 75 C, making the decontamination of personnel a definite possibility. The APPJ has also been shown to oxidize surrogates of the CW agents, Mustard and VX, and a collaborative effort is now proceeding with the actual agents at the Edgewood Chem/Bio Center (ECBC, formerly ERDEC). Efforts are now being directed towards reducing the consumption of He and increasing the working stand-off distance.« less
  • We present a class of compact, monolithic, photonic sensors consisting of multiple section edge emitting lasers with functionalized lateral surface coatings for low level detection of chemical or biological agents. Specifically, we discuss 8 {micro}m x 250 {micro}m Pd-coated H{sub 2} sensors and configurations to reduce the minimum detection limit from 138ppm for passive sensors to 1ppm for active sensors. Compared with conventional optical H{sub 2} sensors that use fiber gratings, surface plasmon resonances, or surface reflectance, our sensors offer the advantages of smaller size, wider dynamic range, monolithic integration of laser source and detector, and 2-D scalability to arraysmore » of sensors that are functionalized to detect different agents.« less
