Analytical study of organophosphorus poisoning

MRIMS Journal of Health Sciences, 2018
Background: Organophosphorus (OP) compounds constitute a heterogeneous category of chemicals specially designed for the control of Pests, weeds or plant diseases. The importance of pesticides in India can be understood from the fact that agriculture is a

Accelerating Materials Discovery: A Review of Machine Learning in X‐Ray Absorption Spectroscopy

Advanced Intelligent Systems, EarlyView.
This review systematically details how machine learning transforms X‐ray absorption spectroscopy (XAS) analysis. It covers advanced deep learning architectures for structure‐spectra mapping and inverse tasks, while discussing key challenges like the simulation‐to‐reality gap.

A structural, spectroscopic and theoretical study of the triphenylphosphine chalcogenide complexes of tungsten carbonyl, [W(XPPh3)(CO)5], X=O, S, Se [PDF]

, 2004
The series [W(XPPh3)(CO)5], X=O, S, Se has been structurally determined by X-ray crystallography and fully characterised spectroscopically to provide data for comparing the bonding of the Ph3PX ligands to the metal.

Infinite Functional Versatility, Formidable Limits: Evaluating Gallium‐Based Liquid Metals in Rechargeable Batteries

Carbon Energy, EarlyView.
Beyond the hype surrounding the self‐healing properties of gallium‐based liquid metals (Ga‐LMs), this perspective critically examines their functional roles in metal‐ion batteries, highlighting both their underlying merits and the often‐overlooked challenges, including non‐representative design and testing configurations, performance overestimations ...

Uncatalyzed Guanosine Phosphorylation under Potentially Prebiotic Conditions

Chemistry – A European Journal, EarlyView.
Pyrophosphate acts as phosphorylating agent of guanosine under simple wet‐dry cycles without condensing agent and inorganic catalysts to afford cyclic guanosine monophosphate derivatives useful for oligomerization in prebiotic processes. ABSTRACT The phosphorylation of nucleosides and their subsequent polymerization are key issues in the study of the ...

Oxidant‐Expedited Synthesis of H‐Phosphonates

European Journal of Organic Chemistry, EarlyView.
An exceptionally mild method for synthesis of alkyl and aryl H‐phosphonates from phosphites is reported, requiring only water and O2 (including air) as reagents. Mechanistic experiments indicate that the role of O2 (and other oxidants) in the transformation is to promote a radical mechanism, and that H2O functions to provide both the hydrogen and the ...
