Enhanced Dehydrogenation and Hydrogenation Capacity of Poly(5‐Vinyl‐1‐Indanol) at Low Temperatures

Polymers for Advanced Technologies, Volume 37, Issue 7, July 2026.
ABSTRACT Redox‐active polymer‐based hydrogen carriers store hydrogen gas through chemical bonding. Although existing redox‐active polymers utilized as hydrogen storage units (e.g., fluorenone and fluorenol) demonstrate reversible hydrogenation in the presence of iridium complex catalysts, they are often hindered by low weight‐based hydrogen storage ...

Organotin-drug interactions. Organotin adducts of tenoxicam: Synthesis and characterization of the first organotin complex of tenoxicam

, 2000
The synthesis and spectral characterization of the novel organotin complexes [SnBu2(ten)] (1) and [SnBu2(Hten)(2)] (2) or the potent and widely used anti-inflammatory drug tenoxicam (H(2)ten) are reported. A crystal-structure determination of 1 showed that, in this complex, the ligand is doubly deprotonated at the hydroxy O-atom and the amide N atom ...

Phosphoryl Halogen and Hydrogen Bonding Controls the Solid‐State Structures of Aryl Halide‐Containing Phosphonates

European Journal of Inorganic Chemistry, Volume 29, Issue 17, 17 June 2026.
Intramolecular (RO)2PO→Halogen interaction versus intermolecular (RO)2PO···HOH hydrogen bonds. Although the O···I distance is shorter than the sum of the van der Waals radii of the atoms involved, there is no covalency involved in this interaction.

Durable Biofouling‐Resistant Coated Fabric Based on Aerogel/Polyurethane for Marine Applications

Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.
A multilayer composite protective fabric (PUC‐CME/KF) is developed by integrating carboxymethyl chitosan/coral extract aerogel and capsaicin‐loaded polyurethane onto a knitted substrate. The material exhibits exceptional extensibility (1963% elongation at break) and sustained capsaicin release.

Developmental toxicity of organotin compounds in animals

Frontiers in Marine Science, 2014
Organotin compounds (OTs) have been used as biocides in antifouling paints and agriculture. The IMO introduced a global ban on the use of OTs in antifouling systems in 2001 due to their high toxicity.

trans-Dichloridobis(dimethyl sulfoxide-κO)bis(4-fluorobenzyl-κC1)tin(IV): crystal structure and Hirshfeld surface analysis

Acta Crystallographica Section E: Crystallographic Communications, 2017
The SnIV atom in the title diorganotin compound, [Sn(C7H6F)2Cl2(C2H6OS)2], is located on a centre of inversion, resulting in the C2Cl2O2 donor set having an all-trans disposition of like atoms. The coordination geometry approximates an octahedron.
