Sorption of p-nitrophenol on two Chinese soils as affected by copper

open access: yes, 2006
Heavy metals and organic contaminants often coexist in soils. However, very little information is available regarding the effect of metals on the sorption of organic contaminants onto soils and/or of organic contaminants on metal sorption. In the present

A Selective Phenyl Azo Acetate Substrate for Enhanced Carbonic Anhydrase Functional Analysis

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Carbon dioxide (CO2) sequestration is a key strategy for mitigating climate change, and biocatalytic approaches offer sustainable, cost‐effective alternatives to chemical and physical methods. Carbonic anhydrases (CAs) efficiently catalyse the reversible hydration of CO2 to bicarbonate, yet their large‐scale application is constrained by ...

Phytochemical Profiling, Antiplatelet Potential, and Cytotoxic Assessment of Thymelaea tartonraira Aerial Part Essential Oil: In Vitro and In Silico Studies

open access: yesChemistry &Biodiversity, Volume 23, Issue 6, June 2026.
Essential oil from Thymelaea tartonraira was characterized by GC–MS and evaluated using in vitro and in silico approaches. The oil exhibited notable antiplatelet activity with low cytotoxicity. Molecular docking revealed strong interactions of major compounds with GPVI, COX‐1, and P2Y12, supporting its potential as a natural antiplatelet agent ...

Frequency effect on p-nitrophenol degradation under conditions of strict acoustic and electric control

open access: yesWater Science and Engineering, 2011
The process of decomposing p-nitrophenol (PNP) with power ultrasound requires strict control of acoustic and electric conditions. In this study, the conditions, including acoustic power and acoustic intensity, but not ultrasonic frequency, were ...

Smiles/Pudovik/Phospha–Brook Cascades from Passerini–Smiles Adducts

open access: yesChemistryEurope, Volume 4, Issue 6, June 2026.
The Passerini–Smiles reaction of aliphatic ketophosphonates affords starting materials for complex cascades triggered by a first Smiles rearrangement. The cascade showcases the power of phosphorous based transformations. Here the reversibility of the Pudovik reaction allows a further Truce–Smiles reaction enol before final Pudovik/Phosph–Brook sequence.

Antioxidant Activity and Inhibition of Carbohydrate Hydrolyzing Enzymes by Underutilized Parts From Some Plant‐Based Foods and Their Effect on Postprandial Hyperglycemia

open access: yesFood Chemistry International, Volume 2, Issue 2, Page 285-294, June 2026.
The underutilized parts viz: pawpaw seed, banana, plantain, and potato peels showed promising antioxidant and inhibition of α‐amylase and α‐glucosidase activities (IC50 values ≤ 100 μg/mL). Similarly, pawpaw seed, banana, plantain, and potato peels reduced postprandial hyperglycemia in sucrose‐ and maltose‐induced hyperglycemia in rats.
