A Review on Vehicle Tire Elastomers and Tire Wear Particles: Composition, Degradation Mechanisms, Analytical Methods, and Predictive Multiscale Computational Modeling

Advances in Polymer Technology, Volume 2026, Issue 1, 2026.
The study of the properties, chemical composition, and degradation patterns of rubber materials used in vehicle tires remains a complex and interdisciplinary task. Rubber for tires—more precisely, complex mixtures of elastomers containing fillers, plasticizers, binders, and other additives—is a condensed chemically active material, the composition and ...

Isothiazole dioxide derivative 6n inhibits vascular smooth muscle cell proliferation and protein farnesylation

, 2005
Isothiazole dioxides have been shown to inhibit Trypanosoma brucei protein farnesyltransferase (PFTase) in isolated enzyme, but elicited only a minor effect on mammalian PFTase.

Carbon and Heteroatom Activation via N‐Heterocyclic Carbene‐Bound Dearomative Intermediates for Stereoselective Annulation Reactions

Chemistry – A European Journal, Volume 31, Issue 66, November 25, 2025.
Use of N‐heterocyclic carbenes (NHCs) to activate carbon and heteroatoms in aromatic compounds is reviewed based on key dearomative NHC‐bound intermediates, i.e., ortho‐quinodimethanes (o‐QDMs), ortho‐quinone methides (o‐QMs) and aza‐analogs (aza‐o‐QMs), aza‐fulvene and triaza‐diene intermediates.

Photochemische Permutation von Indazolen zu Benzimidazolen

Angewandte Chemie, Volume 137, Issue 29, July 14, 2025.
Hier stellen wir eine photochemische Strategie für die direkte Permutation von 1H‐ und 2H‐Indazolen zu Benzimidazolen vor. Dieser Ansatz beruht auf einem zweistufigen Mechanismus aus Tautomerisierung im angeregten Zustand und photochemischer Umlagerung, bietet einen breiten Anwendungsbereich, hohe Ausbeuten und funktionelle Gruppentoleranz und erhöht ...

Electrospinning of pyrazole-isothiazole derivatives: nanofibers from small molecules

, 2019
We investigate the electrospinning of small molecules, specifically designed peptide derivatives of the pyrazole-isothiazole scaffold. Such non-natural peptides enhance the spectrum of fundamental materials used for electrospinning.

Photochemical Conversion of Indazoles into Benzimidazoles

Angewandte Chemie International Edition, Volume 64, Issue 29, July 14, 2025.
We present a photochemical strategy for transforming 1H‐ and 2H‐indazoles into benzimidazoles, enabling heteroaromatic interconversion under mild conditions. This approach, grounded in a two‐step mechanism of excited‐state tautomerization and photochemical rearrangement, offers broad scope, high yields, and functional group tolerance, expanding the ...
