A device is provided that can be rapidly decontaminated in response to exposure to toxic chemicals and biological materials. The device combines electroluminescence (EL) surfaces and panels with a reactive coating including a dye that acts to neutralize toxic chemical and biological materials. A current is applied to an EL display that has been coated with a fluorescent dye. The dye in turns converts nearby ambient oxygen to the more reactive singlet oxygen form that is responsible for the decontamination of toxic chemicals and agents in proximity to the device. Potential uses of the reactive decontamination device include surface panels of vehicles, exterior and interior surfaces of buildings, furniture, wands, and flexible surfaces such as tarps for tents, as well as fabrics and textiles, both woven and non-woven.

Detoxifying light emitting device and use thereof

The present invention relates to single thread composite fibers comprising at least one binder and at least one active catalyst for the capture and degradation of chemical threats such as chemical warfare agents (CWA), biological warfare agents, and toxic industrial chemicals (TIC) and a method for producing the same. The invention fibers are applicable to the fields of protective garments, filtration materials, and decontamination materials.

Single threaded composite fibers and yarns for the degradation of and protection against toxic chemicals and biological agents

A solid particulate reactive sorbent for decontaminating toxic chemical and biological agents and its method of making. The reactive sorbent comprising a plurality of aggregates formed from linked hydrophilic nanoparticles and individual nanoparticles that bind at least one detoxifier, such that the sorbent absorbs the agents, allowing the detoxifier to oxidize and decontaminate the agents for removal. More preferably, the hydrophilic nanoparticles comprise fumed silica and the detoxifier comprises hydrogen peroxide.

Protective technology with reactive solid sorbent for oxidative decontamination of toxic materials

A method and composition of matter for detecting and decontaminating hazardous chemicals, the composition of matter including: a magnetic material for any of chemisorbing, molecularly dissociating, or decomposing a hazardous chemical, wherein the magnetic material changes its magnetic moment upon any of chemisorption, decomposition, and molecular dissociation of the hazardous chemical and the change in magnetic moment is used to detect the presence of the hazardous chemical, and wherein the hazardous chemical includes any of toxic industrial chemicals, chemical warfare agents, and chemical warfare agent related compounds.

A residual life indicator for determining the residual life of a filter has a first sample filter with an inlet coupleable to an inlet of the filter whose residual life is to be determined, a second sample filter having an inlet coupleable to an outlet of the filter whose residual life is to be determined, a chemical tracer source selectively coupled to the inlets of the first and second sample filters, and a detector selectively coupled to outlets of the first and second filters.

Residual life indicator

A process for removing epoxides from a process stream over a wide range of temperature and relative humidity, comprising the step of contacting the process stream with a filtration media comprising an acid form of a mesoporous zeolite produced from pentasil zeolite treated with a caustic agent, for a sufficient time to remove the epoxides therefrom.

A mechanical device is used to estimate a service life of an air filter exposed to a certain chemical at various concentrations, flow rates, and relative humidity conditions. The device includes two members, one of which has at least one window, connected so that their surfaces are movable relative to one another. One member has numerical values for chemical concentrations and service life estimates printed on it. The member having windows has at least one mark printed on it by which it can be oriented relative to the chemical concentration scale on the other member. When the two members are aligned relative to a chemical concentration of interest, the corresponding service life estimate is displayed in an appropriate window.

Filter service life estimator

A material for filtering NOand nitric acid vapors from air over a wide range of humidities and temperatures including a porous hydrophobic substrate and an amine is provided.
