Room temperature, light promoted trimerization of a monomeric complex [Cu(HL)(L)](NO(3)).H(2)O (HL =N,N-dimethyl-N[prime or minute]-propylsalicylideneimine) dissolved in CH(2)Cl(2), was observed with the concomitant generation of new ligand moiety (ClCH(2)L).

Tire wear particles (TWPs) are considered the one of most significant non-exhaust particle emission sources from vehicles. However, there is a lack of research on the emission characteristics of TWPs based on typical driving information. In this work, we used a high-dynamic outside wheel test platform to conduct tire wear tests on multiple types of tires based on a novel test cycle and comprehensively analyzed the differences in their emission characteristics while considering various factors, such as front/rear tire and tire type.

Understanding and effectively controlling molecular conformational changes are essential for developing responsive and dynamic molecular systems. Here, we report that an oriented external electric field (OEEF) is an effective catalyst for the cis-trans isomerization of stiff-stilbene, a key component of overcrowded alkene-based rotary motors. This reversible isomerization occurs under ambient conditions, is free from side reactions, and has been verified using ultraperformance liquid chromatography and UV-vis absorption spectroscopy.

Electrolyzed acidic water (EAW) contains hypochlorous acid as its active compound, which is a potent antimicrobial. It was encapsulated in polymeric coatings and applied to the surface of eggs. The antimicrobial activity and the ability to extend the shelf life of eggs at ambient temperature for 45 days were evaluated, by physical, microbiological, and sensory analyses.

Borohydrides, known for ultrahigh hydrogen density, are promising hydrogen storage materials but typically require high operating temperatures due to their strong thermodynamic stability. Here we introduce a novel light-induced destabilization mechanism for hydrogen storage reaction of borohydrides under ambient conditions photogenerated vacancies in LiH. These vacancies thermodynamically destabilize B-H bonds through the spontaneous "strong adsorption" of BH groups, which trigger an asymmetric redistribution of electrons, enabling hydrogen release at near room temperature, approximately 300 °C lower than the corresponding thermal process.

A novel solid electrolyte sensor with considerably improved response times is presented. The new so-called eFIPEX [etched flux (Φ) probe experiment] is based on the FIPEX [flux (Φ) probe experiment] sensor applied for the measurement of molecular and atomic oxygen concentrations. A main application is the measurement of atmospheric atomic oxygen aboard sounding rockets up to altitudes of 250 km.
