A transition-metal-free oxidative N-N bond formation strategy was developed to generate various structurally interesting [1,2,4]triazolo[1,5-a]benzazoles efficiently. The mechanism of the key oxidative N-N bond formation was investigated by using an intramolecular competition reaction. Notably, the first single crystal structure was also obtained to confirm the structure of 2-aryl[1,2,4]triazolo[1,5-a]benzimidazole.

Controlled and optimized heterogenic interfacial coupling is the key to enhance the electrochemical performance. Herein, for the first time, telluride-based CoS/CoTe heterostructure is reported as a bifunctional catalyst for energy-efficient H generation. Detailed investigations suggest that the heterogenic interfacial coupling leads to superior bifunctional electrochemical performance of the CoS/CoTe heterostructure.

This study explores the use of propylene oxide-modified ethylenediamine (PPO-EDA) as a novel crosslinker and chain extender in polyurethane (PU) adhesives. PPO-EDA was synthesized and compared with ,-dimethylethylenediamine (DMEDA) to assess its impact on mechanical properties and adhesion performance. Key parameters such as NCO conversion, tensile strength, and lap shear strength were thoroughly evaluated.

A first -type tricyclic 8-8-8 (three fused-8-membered ring) laddersiloxane functionalized with four azido groups was successfully synthesized through efficient and highly selective hydrosilylation and nucleophilic substitution, achieving an excellent overall yield. The starting material, a tetravinyl-substituted 8-8-8 laddersiloxane, was prepared via a straightforward and scalable method. The obtained azido-functionalized ladder compound, fully characterized, constitutes a versatile building block for hybrid materials.

Manganese ions (Mn) are an immune activator that enhances the activation of both cGAS and STING proteins. The STING signaling activation and subsequential immune responses are predominantly associated with endoplasmic reticulum (ER). Therefore, ER targeting of Mn in the subcellular compartments would promote the activation of STING signaling pathways.
