The invention relates to degradation of organophosphate neurotoxins with molybdenum complexes. In particular, the degradation of phosphate ester neurotoxins can be performed with molybdenum peroxo complexes resulting in recoverable phosphorus-containing compounds.
CATALYST FOR HYDROGENATION REACTION AND METHOD FOR PRODUCING SAME
A catalyst for a hydrogenation reaction including a polymer support and a catalytic component supported on the polymer support. The polymer support consists of a repeating unit represented by any one of Formulae 5 and 7 to 13.
METALLOPOLYMERS FOR CATALYTIC GENERATION OF HYDROGEN
Metallopolymers composed of polymers and catalytically active diiron-disulfide ([2Fe-2S]) complexes are described herein. [FeFe]-hydrogenase mimics have been synthesized and used to initiate polymerization of various monomers to generate metallopolymers containing active [2Fe-2S] sites which serve as catalysts for a hydrogen evolution reaction (HER). Vinylic monomers with polar groups provided water solubility relevant for large scale hydrogen production, leveraging the supramolecular architecture to improve catalysis. Metallopolymeric electrocatalysts displayed high turnover frequency and low overpotential in aqueous media as well as aerobic stability. Metallopolymeric photocatalysts incorporated P3HT ligands to serve as a photosensitizer to promote photoinduced electron transfer to the active complex.

Reversibly cross-linkable foam is provided. The reversibly cross-linked foam includes a first polymeric material, at least one reversibly cross-linkable monomer polymerized with the first polymeric material, and at least one blowing agent. The reversibly cross-linkable co-polymeric foam is thermally stable at temperatures of at least 10 degrees higher than otherwise identical polymeric foam that does not include the reversibly cross-linkable agent polymerized with the first polymeric material.

DISSOCIABLE NANOPARTICLES WITH INTER ALIA TRANSITION-METAL COMPLEX CATALYSTS
Nanoparticles for use in assay methods for detecting analytes in samples, which comprise a signal inducing agent, e.g. a transition-metal catalyst or a chemiluminophore, a chemiluminophore precursor, a soluble absorber, or a soluble absorber precursor. After binding to an analyte, the nanoparticle is dissociated by a chemical or physical trigger, e.g. an organic solvent or ultrasound, to release the signal inducing agent, which releases a detectable signal via a physical or chemical reaction. The nanoparticles comprising a chemiluminophore, a chemiluminophore precursor, a soluble absorber, or a soluble absorber precursor can also effect chemical reactions that serve as signal amplifiers.
