Reductive dehalogenation of aryl halides by the nanometric sodium hydride using lanthanide chloride as catalyst

, 1997
Sodium hydride of nanometric size exhibits high reactivity for the reductive dehalogenation of aryl halides in the presence of a catalytic amount of lanthanide chloride or a mixture of lanthanide chloride and transition metal chloride.

Sol-Gel Heterogeneization of an Ir(III) Complex for Sustainable Visible-Light Redox Photocatalysis

Molecules
Photocatalysis is a key strategy for the development of sustainable solar-driven chemical processes. In this work, we report the synthesis and characterization of a novel organometallo–ionosilica material derived from the self-condensation of an ...

Reductive Transformations of Anthropogenic Chemicals in Natural and Technical Systems

CHIMIA, 1997
Reductive transformation reactions of chemical pollutants (e.g., polyhalogenated hydrocarbons, aromatic azo and nitro compounds, chromium(VI) species) in the environment are important both from an ecotoxicological and from an environmental ...

Reductive Dehalogenases Come of Age in Biological Destruction of Organohalides

, 2015
Halogenated organic compounds (organohalides) are globally prevalent, recalcitrant toxic, and carcinogenic environmental pollutants. Select microorganisms encode enzymes known as reductive dehalogenases (EC 1.97.1.8) that catalyze reductive ...

Evaluation of carbon isotope fractionation during anaerobic reductive dehalogenation of chlorinated and brominated benzenes

, 2018
Compound specific stable isotope analysis (CSIA) has been established as a useful tool to evaluate in situ biodegradation. Here, CSIA was used to determine microbial dehalogenation of chloro- and bromobenzenes in microcosms derived from Hackensack River ...

X-ray irradiation simultaneously mitigates chlorfenapyr and azoxystrobin residues and preserves postharvest quality of cowpea

Food Chemistry: X
Cowpea faces a residue-quality trade off during postharvest storage, requiring effective pesticide dissipation without accelerating quality deterioration.
