The large area of the human skin and its exposed position on the body surface make it an important portal of entry for toxic agents. Pesticides are able to penetrate the skin and reach the systemic blood and other tissue. Pericor Science has developed atechnology by means of which a pesticide-degrading enzyme can be coupled to the cornified layer of the human epidermis by covalent bonds introduced ...

Proper protective clothing offers the potential of significant reduction of battlefield casualties due to flame/thermal hazards. However, current procedures for testing the flame/thermal protective performance of military clothing fabric samples areunsatisfactory for routine automated evaluations. These test methods are either highly simplified without evaluation of skin burn injuries or too com ...

Physical Sciences Inc. (PSI) proposes to develop biodegradable obscurants operating over the infrared wavelength range using variants of an electroactive polymer. High aspect ratio fibers and flakes of the polymeric material in the size range necessary toprovide full coverage of the infrared spectrum will be produced through electrospinning and electrospraying. The degradation of the polymer wil ...

Not Available "Physical Sciences Inc. proposes to augment AIRIST, its LWIR hyperspectral imaging spectrometer technology, to enable polarization-selected imaging. The resulting spectrometer will enable the detection of surface contamination based on enhancedreflectivity of either s-polarized or p-polarized light. Calculations suggest that surface-deposited persistent liquid chemical warfare agen ...

"Unexploded ordnance (UXO) such as TNT, HMX and RDX from buried landmines and waste munitions are a threat to both military and civilian populations. Detection of UXO can be accomplished by using a highly luminescent material whose luminescent propertieschange upon interaction with a target explosive compound. Physical Sciences Inc. (PSI) proposes to develop a polymeric detection system which wi ...

Physical Sciences Inc. (PSI) proposes to develop a novel process to making proton exchange membrane fuel cell (PEMFC) electrodes using carbon nanofibers. The innovation put forth in this proposal is the use of electrospinning to fabricate a nanoscalefiber network with both the interconnectivity and the surface area properties of ultrahigh aspect ratio fiber networks. Electrodes fabricated from n ...

Physical Sciences Inc. (PSI), in conjunction with the University of California, Berkeley proposes to develop and demonstrate a biochemical-specific standoff sensor for detection of biological warfare agents (BWAs). Differential absorption LIDAR (DIAL)methodology will be used to provide chemical and biological specificity. Our innovation is the extension of DIAL technology to Far-IR (THz) wavelen ...

"Physical Sciences Inc. (PSI) proposes to develop a closed loop focus control system based upon interactions of the human visual system with a novel NVD optical design. The common feature of existing auto-focus systems is that they depend directly in someway on some information contained in the scene being imaged. The proposed control system uses a key parameter needed to control focus which is t ...

Physical Sciences Inc. (PSI) proposes to develop a real-time nuclear detection system for explosives in mines. Mounted on a vehicular platform, this mine detection sensor will be capable of supporting tactical countermine operations as a confirmatory oreven primary sensor system. The advanced mine detection technique will be based on an advantageous combination of pulsed thermal neutron analysis ...
