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.

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.

An assembly containing a shelf-stable formulation for decontaminating skin exposed to toxic compounds located in a package formed with water and potassium bicarbonate in a first chamber; and a sponge, diacetylmonoxime (DAM), and polyethylene glycol (PEG) located in a second chamber. The package includes a barrier between the first chamber and the second chamber, with the barrier being configured to be rapidly removed when needed to enable the water and potassium bicarbonate to enter the second chamber. The package is made by placing the water and potassium bicarbonate in the first chamber of a package; mixing the DAM with PEG to form a DAM:PEG mixture; infusing the sponge with the DAM:PEG mixture to distribute DAM within the sponge; and placing the sponge, DAM and PEG in a second chamber of the package. Infusing the sponge includes solubilizing the DAM:PEG mixture in ethanol or another low boiling point solvent to form an ethanol-DAM-PEG solution and applying the ethanol-DAM-PEG solution evenly to the sponge. The ethanol is removed by applying heat and/or vacuum to the sponge.

The invention is directed toward mutant, non-wild-type organophosphorus acid anhydrolase enzymes having three site mutations, methods of production, and methods of use to effectively degrade toxic organophosphorus compounds, most preferably GP (2, 2-dimethylcyclopentyl methylphosphonofluoridate).

Disclosed herein are methods for the large-scale production of a highly thermally stable acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). Additionally, the expression methods disclosed herein can produce ChE preparations consisting of extract or purified forms that can be produced in high amounts and are highly thermally stable. These ChE products can be used in vitro detection, detoxification and decontamination methods.

A polymer-based material includes a polymeric binder and one or more porous active materials that adsorb, chemisorb, decompose, or a combination thereof, a hazardous chemical. The polymeric binder and the one or more porous active materials are combined to form a composite bead. The polymeric binder may include a polyurethane or a styrene-based block copolymer. The porous active materials may comprise metal-organic frameworks, metal oxides, metal hydroxides, and metal hydrates. The one or more porous active materials may be between 1 and 99 wt % of a total composite mass of the composite bead. Alternatively, the one or more porous active materials may be between 80 and 95 wt % of a total composite mass of the composite bead. The hazardous chemical may include a chemical warfare agent, a simulant of chemical warfare agents, and toxic industrial chemicals.

A method of using a metal organic framework (MOF) comprising a metal ion and an at least bidendate organic ligand to catalytically detoxify chemical warfare nerve agents including exposing the metal-organic-framework (MOF) to the chemical warfare nerve agent and catalytically decomposing the nerve agent with the MOF.

Nanoplatelet forms of metal hydroxide and metal oxide are provided, as well as methods for preparing same. The nanoplatelets are suitable for use as fire retardants and as agents for chemical or biological decontamination.
