Trace Elements in Total Atmospheric Deposition Directly Measured Over the Caribbean Region: Natural Versus Anthropogenic Sources and Geographic Origin

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Dust, sea salt, and anthropogenic and biogenic particles in total atmospheric deposition are sources of essential elements that can significantly impact biogeochemical cycles in the Atlantic Ocean and in islands of the Caribbean region. This unique 41‐month data set records direct sampling of total atmospheric deposition from March 2015 to ...

Mechanochemical Degradation and Fluoride Recovery of Perfluorosulfonic Acid Polymer Membrane

ChemSusChem, Volume 19, Issue 15, 14 August 2026.
The mechanochemical degradation of a perfluorosulfonic acid polymer (PFSA) used in fuel cells, was studied. The products were characterized by various techniques including nuclear magnetic resonance spectroscopy, scanning electron microscopy−energy dispersive X‐ray spectroscopy and liquid chromatography−mass spectrometry.

Design of Hetero‐Core Fiber‐Optic SPR Sensor for Reliable Detection of Geothermal Scale Deposition

Advanced Sensor Research, Volume 5, Issue 8, August 2026.
A hetero‐core fiber‐optic SPR sensor provides rapid and reproducible monitoring of geothermal scale deposition. The mechanically robust design improves fabrication consistency and sensitivity compared with conventional sensors. Distinct peak shifts are observed for silica, carbonate, and sulfate scales, enabling fast, in situ evaluation of scale ...

Heme‐NO Dilates Arteries via Mobilization of NO Moieties From an Intracellular NO Store Within Vascular Smooth Muscle Cells

Advanced Science, Volume 13, Issue 43, 3 August 2026.
Nitrosyl heme emerges as an extracellular nitrodilator that dilates arteries without crossing the cell membrane. Instead, heme‐NO mobilizes NO moieties from a preformed intracellular NO store within vascular smooth muscle, providing both functional and chemical evidence for the NANOS model, revealing a previously unrecognized mechanism of arterial ...

Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

Advanced Science, Volume 13, Issue 46, 17 August 2026.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.

Enhancing Biogenic Formic Acid Production in the Modified OxFA Process by Acetonitrile Addition

Advanced Science, Volume 13, Issue 43, 3 August 2026.
In this study, the beneficial effect of using acetonitrile as a co‐solvent in the modified OxFA process is shown, outperforming methanol, demonstrating improved reaction kinetics combined with high selectivity for the HPA‐2 (H5PV2Mo10O40) catalyzed oxidation of xylose to FA.
