Oxidation State Determines Solvent Structure Around a Manganese–Vanadium Polyoxometalate Water‐Oxidation Catalyst

Angewandte Chemie International Edition, EarlyView.
Oxidation state controls microsolvation in the polyoxometalate {MnV}n−$\{{\rm MnV}\}^{n-}$ water‐oxidation catalyst in acetonitrile/water mixtures. The reduced species {MnV}3− attracts a highly structured hydration layer even at low water content, preferentially binding terminal V═O sites and excluding acetonitrile, while oxidized species show weaker ...

Compositional Characterization, Quality Parameters, and Physicochemical and Bioactive Properties of Pequi (Caryocar brasiliense) Oils From Xingu and Cerrado in Mato Grosso, Brazil

Journal of the American Oil Chemists' Society, EarlyView.
Cerrado oil is richer in MUFA and antioxidant compounds, while Xingu oil shows higher SFA and enhanced oxidative stability, reinforcing the potential of pequi oil as a sustainable bioactive ingredient. ABSTRACT Pequi (Caryocar brasiliense) is a native fruit widely distributed in Brazilian biomes, specially in Cerrado, known for its high oil yield and ...

Synthesis and Interfacial Behavior of Mixed Potassium N‐Lauroyl/N‐Myristoyl Glycinate Surfactants With Varying Alkyl Chain Ratios

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Biodegradable and low‐irritant amino acid–based surfactants have attracted considerable attention as environmentally friendly alternatives to conventional petroleum‐derived surfactants. In this study, a series of acyl amino acid surfactants with identical amino acid head groups but different alkyl chain lengths were synthesized via a modified ...

Metabolic fate of drugs of abuse and new psychoactive substances: A pilot study on a novel workflow using a zebrafish embryo model combined with human microdosing

British Journal of Clinical Pharmacology, EarlyView.
Aim The aim of this study was to develop a novel workflow to identify human urine biomarkers for drugs of abuse and new psychoactive substances. Metabolites of amphetamine, cocaine, LSD, MDMA, methamphetamine, THC, MDMB‐CHMICA, and MDPPP were first identified in a zebrafish embryo (ZE) metabolism study followed by comparison to most abundant human ...
