Synthesis of Sulfated Sn–Zr Mesoporous Catalysts for the Selective Dehydration of Hexose‐Type Monosaccharides

open access: yesChemistryOpen, EarlyView.
The synthesized SO4/Sn–Zr–SBA‐15 shows high activity in fructose‐to‐5‐hydroxymethylfurfural (HMF) dehydration. Acid sites with positive synergy effect between metals and SO4= improve catalytic behavior Synthesis of combined Brønsted and Lewis acid sites in SBA‐15 by Zr and Sn incorporation onto the mesoporous support, followed by a sulfation procedure ...

Construction of a Fluorescence‐Based Logic Gate Seeing the Effect of Perchlorate Ions on Hemicyanine Dye–β‐Cyclodextrin Complexes to Certify Safe Drinking Water

open access: yesChemistryOpen, EarlyView.
A method to detect perchlorate ions and certify safe drinking water by constructing a fluorescence‐based logic gate considering the binding of a hemicyanine dye with β‐CD is presented. Perchlorate ions (ClO4−) are prevalent contaminants in the surface, and drinking water that disrupt thyroid function by competitively inhibiting the sodium‐iodide ...

Impact of Sonication Treatment on Physicochemical Properties of Carbon Blacks and Pt/C Catalysts in Proton Exchange Membrane Fuel Cells

open access: yesParticle &Particle Systems Characterization, EarlyView.
Here it is revealed how ultrasonic dispersion chemically and structurally alters Pt/C catalysts depending on carbon black type. While high surface area carbons remain stable, low and medium surface area carbons undergo oxidation, increasing charge‐transfer resistance and degrading fuel cell performance.

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Harnessing Natural Compounds in Psoriasis: Targeting Cellular Pathways for Effective Therapy

open access: yesPhytotherapy Research, EarlyView.
Natural compounds act on key cellular pathways in psoriasis by suppressing keratinocyte hyperproliferation, modulating Th17/IL‐17‐mediated immune responses, and reducing oxidative stress. These multi‐target effects highlight their potential as safer adjunctive therapies alongside conventional treatments.

Thermal Regimes of Beaver‐Impacted Stream Reaches in the Tualatin River Basin, Oregon, United States

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT As beavers are increasingly used in stream restoration, interest in their potential to mitigate stream degradation has grown. However, the impacts of beaver dams on stream temperature remain inconsistent across studies, often due to differences in spatial scale and methodology.

Upcycled PET‐Derived Carbon Foam Functionalized with Cu3SbS4–Sb2S3 Heterostructures for Efficient Interfacial Solar Desalination

open access: yesSmall, EarlyView.
Carbon foam is upcycled from waste PET and decorated hydrothermally with Cu3SbS4‐Sb2S3 to prepare a photothermal evaporator. The Cu3SbS4‐Sb2S3/CF reveals superior photothermal performance with excellent evaporation rate under one‐sun radiation. This renewable‐based sustainable strategy enables circular economy practices that suggest a promising ...
