Enhanced Oxidase‐Like Activity of Ag‐Decorated V2O5 Hollow Microspheres for the Colorimetric Detection of Mercury (II) Ions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this work, we report the synthesis of a novel Ag‐decorated V2O5 nanozyme with intrinsic oxidase‐like activity for the colorimetric detection of Hg2+ ions. The Ag/V2O5 hollow microspheres were synthesized via a simple hydrothermal method followed by Ag nanoparticle decoration and thoroughly characterized by XRD, XPS, SEM, TEM, HRTEM, and EDX.

Effective acetalization of furfural catalyzed by Fe‐ and Co‐oxalates: impact of alcohols structure on products composition

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Fe‐, Co‐, and FeCo‐oxalates supported on silica gel (5 wt% metal load) were synthesized, characterized, and tested for the first time in solvent‐free furfural (FF) acetalization with C1–C8 alcohols at 70–170 °C under both conventional and microwave (MW)‐assisted conditions. The interaction of FF with linear C1–C4 alcohols yielded pincer‐shaped

MitoTEMPO Prevents Oxalate Induced Injury in NRK-52E Cells via Inhibiting Mitochondrial Dysfunction and Modulating Oxidative Stress

Oxidative Medicine and Cellular Longevity, 2017
As one of the major risks for urolithiasis, hyperoxaluria can be caused by genetic defect or dietary intake. And high oxalate induced renal epithelial cells injury is related to oxidative stress and mitochondrial dysfunction.

Metagenomic and phylogenetic analyses reveal gene-level selection constrained by bacterial phylogeny, surrounding oxalate metabolism in the gut microbiota

mSphere
The gut microbiota is critical for neutralizing dietary toxins. Oxalate is a toxin commonly produced by plants to deter herbivory and is widely consumed in the human diet.

Insight into the in-cloud formation of oxalate based on in situ measurement by single particle mass spectrometry

, 2017
. While ground-based works suggest the significance of in-cloud production (or aqueous formation) to oxalate, direct evidence is rare. With the in situ measurements performed at a remote mountain site (1690 m above sea level) in southern China, we first ...

Recent Advances in Tailoring Active Site Microenvironments of Fe–N–C Catalysts for Oxygen Reduction

ChemistryEurope, EarlyView.
This review summarizes the main factors affecting Fe–N–C catalysts for ORR: activity depends on active site structure, electronic configuration, and porosity, while stability is limited by metal leaching, carbon degradation, and inactive phase formation.
