Promotional Effect of Bimetallic PtSn/C Catalysts for the Selective Synthesis of Glucaric Acid via Glucose Oxidation

ChemCatChem, Volume 18, Issue 15, 14 August 2026.
PtSn/C catalysts were synthesized and evaluated for the oxidation of glucose to glucaric acid. The reaction proceeds through sequential oxidation of the C1 aldehyde and C6 hydroxyl groups, followed by oxidation of the C6 aldehyde. Pt activates O2, while SnOx promotes adsorption of glucose‐derived intermediates, enabling selective glucaric acid ...

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China

Geological Journal, Volume 61, Issue 8, Page 2258-2278, August 2026.
Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.

Chemical Profiling and In Vitro Assessment of Antioxidant and Antimicrobial Properties of Algerian Erica arborea L. Extracts, Strengthened by Molecular Modeling Analysis

ChemistryOpen, Volume 15, Issue 8, August 2026.
Erica arborea L. from Algeria was valorized via chemical profiling and bioactivity assessment. The EtOAc extract showed the highest levels of polyphenols, flavonoids, and flavonols. It exhibited strong antioxidant (ABTS•+, DPPH•, FRAP) and antibacterial activity (S. aureus, B. subtilis).

Putative Mechanisms for Initial Reaction of Anaerobic Benzene Degradation Presumably Involving a Flavoprotein

Environmental Microbiology, Volume 28, Issue 8, August 2026.
Anaerobic biodegradation of benzene by sulphate‐reducing strain BzS1 was studied by combining genomics, differential proteomics and targeted metabolite analyses. Strain BzS1 has an exceptionally streamlined metabolism. A highly abundant heterotrimeric flavoprotein may add benzene to either enolpyruvate or glutaconyl‐CoA followed by channelling into the

Reassessing the organic carbon budget in the Murchison meteorite through an extraction–recovery mass‐balance approach

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1729-1741, August 2026.
Abstract A substantial fraction of organic carbon in carbonaceous chondrites has long been described as “missing,” reflecting incomplete recovery and limited resolution of operationally defined organic components. Here, we present a quantitative reassessment of the carbon budget in the Murchison meteorite using an integrated extraction–recovery mass ...

Formation and evolution of shale overpressure in deep Wufeng-Longmaxi Formation in southern Sichuan basin and its influence on reservoir pore characteristics

Frontiers in Earth Science
In the deep Longmaxi Formation shale gas reservoirs of the southern Sichuan Basin, strong overpressure is universally developed to varying degrees. However, there is currently a lack of in-depth research on the formation mechanisms, evolutionary patterns,

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2048-2072, August 2026.
Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

Assessing the Helium Potential of Variscan Batholiths: Insight From Corsica Island

Geochemistry, Geophysics, Geosystems
Most of the current helium (He) reserves originate from fortuitous discoveries, mainly made during oil and gas exploration in sedimentary basins. As helium generation depends on U and Th α‐decay, old geological provinces gather key ingredients for high ...
