The Versatile Structural World of Methanedi‐ and Trisulfonic Acid and Their Salts
ChemistryOpen, Volume 15, Issue 7, July 2026.The solid‐state structures of the CH4‐derived polysulfonic acids methanedisulfonic acid (MDSA) and methanetrisulfonic acid (MTSA) are presented for the first time. Additionally, a broad overview over possible MDS and MTS salts, containing mostly group I cations, is given and their solid‐state structures are analyzed, showing the structural versatility ...

International Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.ABSTRACT Understanding how vanadium oxide (V2O5) influences the dissolution behavior of nuclear waste glasses is essential for optimizing their waste loading and long‐term durability. In this work, a series of sodium aluminoborosilicate‐based model glasses—(100−x) (30Na2O–5Al2O3–15B2O3–50SiO2)—xV2O5, where x = 0, 2.5, and 5 mol.%—were synthesized to ...

Fast Reduction of Nitroalkenes Into Nitroalkanes Under Continuous‐Flow Chemical Conditions
European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.Flow chemical synthesis was employed for the reduction of nitroalkenes to the corresponding nitroalkanes using sodium borohydride as the reducing agent. The reaction proceeds in only 150 s, affording products from good‐to‐excellent yields (61–96%). Herein, we describe an efficient and rapid continuous‐flow reduction of nitroalkenes to nitroalkanes. The

Processability and Crosslink Density: Role of Peptizers in Natural Rubber and Chlorobutyl Rubber
Journal of Applied Polymer Science, Volume 143, Issue 22, June 10, 2026.This work evaluates how chemical and physical peptizers affect mastication, vulcanization behavior, and network formation in natural rubber and chlorobutyl rubber. Size‐exclusion chromatography, rheometry, DSC, and swelling analyses demonstrate improved processability but reduced crosslink density with peptizer addition.

Sodium Tetraazidoaurate(III)—From Na[AuCl4]·2H2O to Na[Au(N3)4] and Beyond One Step at a Time
Chemistry – A European Journal, Volume 32, Issue 22, 9 June 2026.Novel sodium chlorido‐/azidoaurate(III) dihydrates Na[AuCl4–x(N3)x]·2H2O (x = 0, 1, 2, 3, 4) provide the first example of a complete series of gradual substitution on tetramer complex anions to be described. Controlled dehydration of Na[Au(N3)4]·2H2O leads to Na[Au(N3)4]·H2O and Na[Au(N3)4], the latter being a highly explosive material.
