Titanium dioxide photocatalytic degradation of organophosphonates [PDF]

, 2002
The titanium dioxide mediated photocatalytic degradation of dimethyl phenylphosphonate (DMPP) has been investigated. DMPP can be completely decomposed by irradiation of an aqueous suspension of Ti02 in the presence of oxygen, though the total ...

Highly Mesoporous Zr-Based MOF-Fabric Composites: A Benign Approach for Expeditious Degradation of Chemical Warfare Agents and Simulants. [PDF]

Small
This research unveils a breakthrough in organophosphonate degradation using environmentally friendly mesoporous UiO–66–NH2‐fabric composites. This innovative approach, facilitated by CAPB surfactant, overcomes mass transfer limitations, creating robust, highly porous materials compatible with fragile fabrics.

Semiconductive microporous hydrogen-bonded organophosphonic acid frameworks [PDF]

Nature Communications, 2020
Abstract Herein, we report a semiconductive, proton-conductive, microporous hydrogen-bonded organic framework (HOF) derived from phenylphosphonic acid and 5,10,15,20‐tetrakis[ p ‐phenylphosphonic acid] porphyrin (GTUB5).

Genomic context analysis enables the discovery of an unusual NAD-dependent racemase in phosphonate catabolism. [PDF]

FEBS J
The authors identify PbfF (previously annotated as a NAD‐dependent dehydrogenase) as a hitherto unknown enzyme in phosphonate catabolism. Guided by genome context analysis, they show that PbfF is actually a racemase, serving to degrade the natural compound (S)‐2‐amino‐1‐hydroxyethylphosphonate (S‐HAEP).

Novel Human Butyrylcholinesterase Variants: Toward Organophosphonate Detoxication [PDF]

Biochemistry, 2014
Human butyrylcholinesterase (hBChE) is currently being developed as a detoxication enzyme for stoichiometric binding and/or catalytic hydrolysis of organophosphates. Herein, we describe the use of a molecular evolution method to develop novel hBChE variants with increased resistance to stereochemically defined nerve agent model compounds of soman ...

A Simple and Versatile Approach for the Low‐Temperature Synthesis of Transition Metal Phosphide Nanoparticles from Metal Chloride Complexes and P(SiMe3)3

Advanced Materials, Volume 35, Issue 49, December 7, 2023., 2023
Metal phosphide nanoparticles are prepared under mild conditions following a synthetic approach involving the reaction of metal chloride complexes with tris(trimethylsilyl)phosphine. The formation of Si–Cl bonds in the by‐product SiClMe3 acts as a driving force for the reaction.

A New Family of Layered Metal‐Organic Semiconductors: Cu/V‐Organophosphonates

Small, Volume 19, Issue 47, November 22, 2023., 2023
This work reports a semiconductive layered metal‐phosphonate framework [Cu(H2O)2V(µ‐O)(PPA)2], which exhibits conductivity up to 0.6 S/m and short‐range antiferromagnetic order. [Cu(H2O)2V(µ‐O)(PPA)2] has complex landscape of energy‐states with photoluminescence peaks at 1.8 and 2.2 eV.

Anaerobic dissimilatory phosphite oxidation, an extremely efficient concept of microbial electron economy

Environmental Microbiology, Volume 25, Issue 11, Page 2068-2074, November 2023., 2023
Anaerobic oxidation of phosphite is a very economic way to supply bacteria with both ATP and electrons for assimilation of CO2 into cell material at high growth yields. Abstract Phosphite is a stable phosphorus compound that, together with phosphate, made up a substantial part of the total phosphorus content of the prebiotic Earth's crust. Oxidation of

Steric Control over the Threading of Pyrophosphonates with One or Two Cyanostar Macrocycles during Pseudorotaxane Formation

Chemistry – A European Journal, Volume 29, Issue 41, July 20, 2023., 2023
Control over the binding stoichiometry and the threading kinetics is achieved in pseudorotaxanes comprising the anion‐binding cyanostar macrocycle and organic pyrophosphonates with fine‐tuned steric bulk. The approach allowed the selective assembly of [3]pseudorotaxanes and [2]pseudorotaxanes, and it provided insights that are valuable for future work ...
