Decontamination of chemical and biological threats demands a very reactive solution. It is ideal to generate the decontaminants on-site: the activated decontaminant is highly reactive and quickly destroys chemical and biological warfare agents; prior to activation the ingredients can be safely stored for years, shipped, and handled. TDA's electrochemical decontamination (eClO2) technology u ...

Defense against chemical weapons is a critical DoD requirement. An effective defense requires the development of unique respirator systems that prevent inhalation of chemical warfare (CW) agents. In addition, the protective equipment exposed to CW agents must not pose a residual hazard after use in the battlefield. Existing respirator canisters remove CW agents, but they do not self-decontaminate ...

Physical Sciences Inc. proposes an innovative, filter free approach to rapidly concentrate and detect bacterial spores from large volumes of flowing water for the purpose of early warning detection of contaminated potable water supplies against low concentration biological pathogens. Our approach builds on previous concentration work to study the feasibility of optimizing this approach and lays t ...

Physical Sciences, Inc. (PSI) proposes to demonstrate environmentally benign, low cost biological agent simulant particles that mimic the infrared, scatter, fluorescence and atomic absorption spectra of bacillus subtilis (BG), Erwinia herbicola (EH), and the MS2 Bacteriophage (MS2). These stimulant particles will be composed of materials that are commonly available foods or nutritional supplement ...

Physical Sciences Inc. (PSI) and its partners, Research Support Systems (RSI, a PSI-subsidiary) and Professor Thomas Strohmer of UC Davis, propose to develop an innovative approach that can be employed by an ‘on-the-move’ sensor constellation to determine the size (length, width, and height), absolute geo-location, and 3-D concentration distribution of chemical threat clouds released on battle ...

Physical Sciences Inc. (PSI) and Duke University propose to develop a hybrid, multifunctional, ultraviolet (UV) beam conditioner intended for laser beam switching, deflection, and frequency shifting for quantum computing applications. The beam conditioner consists of three functional blocks, separating the technology for frequency control, fast amplitude control, and electronic beam shuttering int ...

Physical Sciences Inc. and the University of Delaware propose a novel self-healing, damage-sensing, reinforced polymer composite concept for use in degradation-resistant structural applications. In Phase I we investigated the feasibility of a microcapsule-based self-healing system and a damage-sensing functionality. The objective of Phase II is to develop a reinforced composite material that incor ...

Physical Sciences Inc. (PSI) and its academic partner, the Rochester Institute of Technology (RIT), will continue to advance the capability of RIT"s DIRSIG hyperspectral scene simulation software to enable accurate prediction of LWIR reflectance characteristics of liquid-contaminated surfaces. DIRSIG reflectance model and software modifications will be implemented by RIT. In conjunction with RIT ...

The Army desires carbon nanotube (CNT) based fibers with exceptional strength and stiffness to provide high performance composite materials. Physical Sciences Inc. (PSI) has demonstrated a method to fabricate continuous CNT from electrospun polymer nanofibers. Because these CNT are continuous, their mechanical strength is limited primarily to their defect population. During a Phase I program PSI w ...

Physical Sciences Inc., in cooperation with University of Notre Dame, will develop a method for the persistent detection of aerosolized biological warfare agents using a distributed and cooperative sensor network within a Bayesian framework. The proposed system, named BioNet, will provide a wider coverage and two-fold reduction in false alarm rate over individual sensor performance through intelli ...
