No escape from microplastics: Contamination of reef manta ray feeding areas in a remote, protected archipelago

Conservation Science and Practice, EarlyView.
We found microplastic contamination of the upper water column around the Chagos Archipelago, a remote, protected archipelago in the central Indian Ocean. Key aggregation areas for reef manta rays (Mobula alfredi) were contaminated, putting them at risk of microplastic ingestion.

Identification and characterisation of temporal abundance of microRNAs in synovial fluid from an experimental equine model of osteoarthritis

Equine Veterinary Journal, EarlyView.
Abstract Background MicroRNAs, a class of small noncoding RNAs, serve as post‐transcriptional regulators of gene expression and are present in a stable and quantifiable form in biological fluids. MicroRNAs may influence intra‐articular responses and the course of disease, but very little is known about their temporal changes in osteoarthritis ...

A complete inventory of institutional and public meteorite collections in Switzerland

Meteoritics &Planetary Science, EarlyView.
Abstract Museums and universities are important for collecting, maintaining, and curating meteorites. To make specimens known and available for research, inventorying and optimal curation are important. However, not all meteorite collections are well curated, especially in smaller institutions.

Er3+‐doped amorphous tellurite thin films

Journal of the American Ceramic Society, Volume 108, Issue 8, August 2025.
Abstract Radio‐frequency (RF) magnetron sputtering was used to deposit amorphous tellurite thin films from glassy targets from TeO2–ZnO–Na2O/BaO/Bi2O3 system doped with 2.5 mol% of Er2O3. The impact of the sputtering power on the optical, luminescence, and structural properties of the films is discussed.

Experimental methods in chemical engineering: Electron probe micro‐analysis—EPMA

The Canadian Journal of Chemical Engineering, Volume 103, Issue 7, Page 3000-3011, July 2025.
ABSTRACT Electron probe microanalysis (EPMA) is a non‐destructive spectroscopic technique to map the chemical composition—quantitative elemental distribution and layer thickness—with a micro‐scale resolution. An electron beam illuminates the surface of a sample and produces backscattered electrons (BSE), secondary electrons (SE), characteristic X‐rays,

Monolithic 3D Logic Gates Based on p‐Te and n‐Bi2S3 Complementary Thin‐Film Transistors

Advanced Electronic Materials, Volume 11, Issue 8, June 2025.
A method for preparing M3D circuits based on an in situ synthesis process is presented. Through thermal evaporation, followed by a low‐temperature treatment, p‐Te, and n‐Bi2S3 channel materials are easily synthesized. The excellent uniformity enables the fabrication of logic gates beyond inverters.

The Role of Chalcogen Bonding in Organic Dichalcogenides of Biological Interest

Chemistry – An Asian Journal, Volume 20, Issue 10, May 15, 2025.
Experimental and theoretical studies consistently show that selenium and tellurium in dichalcogenides compounds can function as efficient chalcogen bond (ChB) donors. Their electrophilic behavior may suggest that the formation of a ChB could represent the preliminary step of the molecular mechanism resulting in the anti‐redox activity of ...

Two‐Dimensional Titanium Disulfide Nanosheets for Enhanced Capacity of Zinc‐Ion Capacitors

ChemElectroChem, Volume 12, Issue 9, May 5, 2025.
This study explores two‐dimensional titanium disulfide (2D‐TiS2) nanosheets as cathodes for zinc‐ion capacitors (ZnCs). Organolithium exfoliation enhances TiS2’s electrochemical properties, improving capacitance and Zn2+ ion intercalation compared to bulk.
