Mechanistic Insight into H2S‐Induced Fluorescence Quenching in a Robust Metal–Organic Framework

Small, Volume 22, Issue 39, 13 July 2026.
An ultramicroporous Zn‐based metal‐organic framework, MFM‐520, enables reversible hydrogen sulfide adsorption and selective fluorescence sensing. Confinement of H2S within the pores perturbs ligand‐centered excited states through weak host‐guest interactions, enhancing non‐radiative decay pathways.

Tuning Functional Properties of Starch–Pectin Composites by Extrusion

Starch - Stärke, Volume 78, Issue 7, July 2026.
This study demonstrates that extrusion temperature modulates the structural cohesion, water affinity, and rheological properties of composites based on pregelatinized starch and pectin. The findings highlight the potential of thermal processing to tailor the functionality of starch–pectin systems for food and biopolymer applications.

Geochemical investigation of impactites from the Boltysh impact structure and possible relationship to early Danian sediments from the Umbria–Marche Basin, Italy

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1309-1332, July 2026.
Abstract Within the Danian Scaglia Rossa Formation appears a regionally correlatable horizon cutting across multiple sections and outcrops within the Umbria–Marche Basin of NE Italy, where it is intercalated with uniform pelagic carbonate successions. This horizon is called “ALE layer” and has tentatively been interpreted as a fine‐grained volcanic ash.
