Dual‐Emission Switching in a Mn(II)‐Based Hybrid Bromide via Water Coordination: Synthesis, Structure, and Processing

open access: yesAdvanced Optical Materials, Volume 14, Issue 4, 27 January 2026.
This study reports the synthesis, structure, and optical properties of (pr‐ted)2[MnBr4], a luminescent manganese (II) hybrid halide. It shows green emission under UV and transforms into a red‐emitting hydrated phase with humidity, reversible by heat or vacuum. Structural, photophysical, and theoretical analyses confirm the mechanism.

Synthesis, Crystal Structure, Hirshfeld Surface Analysis, and DFT Calculations of Cesium Benzilate Monohydrate: Exploring the Importance of Noncovalent Interactions

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
The novel complex cesium benzilate monohydrate, Cs[C14H11O3]·H2O, was synthesized via the reaction of benzilic acid and cesium carbonate, and high‐purity single crystals were obtained by slow aqueous solvent evaporation. Powder X‐ray diffraction validated the crystalline phase purity.

Host Traits Impact the Outcome of Metagenomic Library Preparation From Dental Calculus Samples Across Diverse Mammals

open access: yesMolecular Ecology Resources, Volume 25, Issue 8, November 2025.
ABSTRACT Dental calculus metagenomics has emerged as a valuable tool for studying the oral microbiomes of humans and a few select mammals. With increasing interest in wild animal microbiomes, it is important to understand how widely this material can be used across the mammalian tree of life, refine the related protocols and understand the expected ...

Historical Collections of Tropical Marine Mammals Are an Excellent Resource for Ancient DNA

open access: yesMolecular Ecology Resources, Volume 25, Issue 7, October 2025.
ABSTRACT The ability to predict ancient DNA sequencing success in natural history collections is critical to reducing the amount of destructive sampling of a finite resource. So far, studies investigating such success have predominantly focused on taxa with ranges restricted to temperate or cold environments at northern latitudes, which likely aids DNA

Influence of Pd/AC Catalytic Properties on the Continuous Production of Hydrogen from Formic Acid

open access: yesChemCatChem, Volume 17, Issue 14, July 2025.
A highly efficient palladium/activated carbon (Pd/AC) catalyst, prepared with PdCl₂ and nanopowdered AC via wet impregnation without stabilizing agents, achieves superior Pd dispersion, and doubling hydrogen yields compared to commercial catalysts. This advancement improves durability, minimizes regeneration frequency, and enables scalable hydrogen ...
