Summary: This study synthesized band gap tunable Cu-Zn-In-S/ZnS nanocrystals (CZIS/ZnS NCs) and used them for potential-resolved ECL detection. By changing the Cu ratio in the precursor, the emission spectrum and potential of CZIS/ZnS NCs could be tuned. A biosensor was fabricated with CZIS/ZnS NCs as signal reporters to detect three types of microRNAs sensitively and selectively.

Summary: A CuO and Cu-doped ZnO S-scheme heterojunction was constructed using Cu-ZIF-8 as precursor, which exhibited outstanding catalytic activation performance and broad-spectrum degradation capacity. The catalyst/visible light/PMS composite reaction system showed remarkable mineralization and anti-interference ability, and is environmentally friendly. The interaction of Cu/Zn bimetallic sites realized effective utilization of PMS and accelerated PMS activation, promoting the formation of highly oxidative SO5 & BULL;. This study provides new systematic insights on PMS activation by Cu/Zn bimetallic oxide S-scheme heterojunction and is significant for sewage purification.

Summary: The urgent need for safe and sustainable energy storage systems for residential buildings has led to research into aqueous zinc ion batteries. However, zinc suffers from irreversibility issues in these batteries. To address this, researchers have used organic cations to induce the decomposition of trifluoromethanesulfonate and build a solid electrolyte interphase (SEI) that enhances the electrochemical performance of zinc batteries. The SEI promotes high Coulombic efficiency, stability, and capacity in zinc batteries.

Summary: By studying native planar Cu foils, it is found that different dominant crystal facets of Cu current collectors have a significant impact on the electrochemical performance of Zn anodes. Zn anodes using Cu foils with Cu-100 or Cu-110 dominant crystal planes show improved first-cycle CE and long cycle life compared to those with Cu-111. This work reveals the crystal facet correlation with the Zn anode electrochemical performance, providing opportunities for the future development of high-energy and long-life Zn metal batteries.

Summary: Metal chalcogenide I-III-VI quantum dots have shown promising potential for optoelectronic applications due to their environmentally friendly composition, high fluorescence, and compositional flexibility. By using highly reactive anionic sources and varying the nominal x values, multinary Zn-Cu-Ga-Se1-xSx QDs with emission tunability from blue to deep red were efficiently synthesized in this work. The resulting QDs exhibited high photoluminescence quantum yields and were utilized in the fabrication of a high-performance white lighting non-Cd QD-light-emitting diode, achieving exceptional color rendering index and peak luminance.
