A method of using select Schiff base compounds for chemical agent detoxification. The method including applying a compound to the contaminated substrate. The compound includes an imine having at least one Schiff base nitrogen and an alkyl substituent or an aryl substituent having an electron acceptor. The at least one Schiff base nitrogen is spaced away from the electron acceptor by a distance ranging from about 200 pm to about 1000 pm. The substrate and the compound are dried. The at least one Schiff base nitrogen of the compound promotes a nucleophilic attack on an electrophilic site of the toxic chemical agent.

This invention is directed toward a non-wild-type organophosphorus acid anhydrolase enzyme having two site mutations, method of production, and method of use to more effectively degrade toxic organophosphorus compounds and, in particular, toxic chemical GD (3,3-Dimethylbutan-2-ylmethylphosphonofluoridate), than the wild type organophosphorus acid anhydrolase.

A method for decontamination of a toxic substance is disclosed. The method includes fabricating a plurality of nanomotors, and putting the plurality of nanomotors in contact with a contaminant solution comprising the toxic substance. Fabricating the plurality of nanomotors includes preparing a mesoporous silica template, forming the plurality of nanomotors within the mesoporous silica template, and separating the plurality of nanomotors from the mesoporous silica template. The mesoporous silica template includes a plurality of channels, where each channel of the plurality of channels have a diameter less than about 50 nm and a length of less than about 100 nm, and each nanomotor of the plurality of nanomotors is formed within a channel of the plurality of channels. Putting the plurality of nanomotors in contact with the contaminant solution includes adding hydrogen peroxide (H.sub.2O.sub.2) and the plurality of nanomotors to the contaminant solution.

The present disclosure relates to the field of decontamination and biocidal agents. More specifically, the invention relates to novel N-halamine melamine derivatives, compositions comprising them, processes for their production, and methods using the same.

A composition for the destruction of chemical warfare agents and toxic industrial chemicals having a polyoxometalate (POM) attached to an amine, carboxylic acid, or ammonium substituted porous polymer. Also disclosed is a method for attaching a POM to an amine, carboxylic acid, or ammonium substituted porous polymer by (1) dissolving the POM in water or an organic solvent, adding the functionalized porous polymer, whereby the POM ionically attaches to the amine, carboxylic acid or ammonium group, or (2) heating the POM and functionalized polymer in the presence of a dehydrating agent whereby an imide bond is produced between the POM and the functionality on the porous polymer.

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.

The present invention relates to a process for decontaminating surfaces contaminated with one or more toxic agents. The processes include contacting a contaminated surface with a porous metal hydroxide which rapidly absorbs the toxic agent from the surface, then decontaminates the agent via reactions involving surface functional groups.

A device for removing toxic or harmful materials from an inside sealed by a sealed-type flexible enclosing cover, wherein the contaminated surface of the subject of decontamination is covered with the enclosing cover and a reactive gas is introduced thereto, and particularly to a decontamination and sterilization device, wherein a plasma generator is fixed to a enclosing cover and a plasma gas containing an active radical generated from the plasma generator is introduced to the inside sealed by the enclosing cover together with a reactive gas having a hydroxyl group such as hydrogen peroxide (H.sub.2O.sub.2), water (H.sub.2O), or an alcohol (C.sub.nH.sub.2n+1OH) to thus increase the production of a reactive radical, whereby the plasma and the reactive gas are intensively applied to the inside sealed by the enclosing cover, thus increasing the contact with contaminants and realizing more efficient decontamination.
