Summary: The study demonstrated a simple strategy for tuning the mechanoluminescence of a flexible composite of zinc sulfide (ZnS) phosphor and all-inorganic CsPbX3 (X = Cl, Br, and I) perovskite quantum dots (PeQDs) by changing the halide component of CsPbX3. This led to a broad color expression with narrow emission band under low stretching-releasing stress. The color conversion between ZnS and PeQDs is a radiative combination and reabsorption process, allowing for full color tuning from 510 to 710 nm due to the bandgap tailoring of PeQDs.

Summary: In recent years, quantum dots (QDs) have emerged as a powerful building block for liquid-crystal display (LCD) technology, particularly in the form of color enhancement films. However, the challenge remains to develop efficient and wide color gamut LEDs for backlighting purposes. This study presents QD-based white LEDs that exhibit a high external quantum efficiency (EQE) of 39.8% and a wide NTSC color gamut coverage of 133.3%. These LEDs utilize giant CdSe/CdS core/shell QDs for red-emitting spectral range and green-emitting CdZnSeS/ZnS alloyed core/shell QDs, resulting in high photoluminescence quantum yield (PLQY) and narrow full width at half maximum (FWHM) values. The incorporation of QDs in liquid matrix on blue LED chips for LCD TV backlighting improves image brightness and color vibrancy, showcasing the potential of QD-based white LEDs for next-generation display technology.

Summary: Hydrophobic side chains in polymers play a significant role in antimicrobial activity and selectivity, with more hydrophobic polymers showing faster bacteria elimination but reduced selectivity at higher percentage content. Highly hydrophobic co-polymers with hexyl-functionalized cyclic carbonate kill bacteria via membrane-disruptive mechanism, with micelle formation leading to lower extent of membrane disruption. This study provides insights into the design of new antimicrobial polymers based on the effects of hydrophobic side chains.

Summary: In this study, a new family of benzothiazole-enolate-based organoboron luminophores (HN1-4) with efficient dual-phase emission was constructed. HN4 exhibited one of the highest quantum yields among similar compounds. The intense emission in the solid state was attributed to the twisted core structure constructed by the boronic coordination of two penta-fluorobenzene in HN4. Additionally, HN4 showed a unique response to mechanical force accompanied by a reversible change of the quantum yield.

Summary: Dynamically controlling supramolecular chirality is crucial for the development of functional chiral materials and their specific function implementation. Light, as an external energy input, provides a remote and accurate means to modulate chiral assemblies. Different methods, such as photochemically reactive units and photo-induced directionally rotating molecular motors, as well as circularly polarized light, have been explored to drive chiral transfer or amplification and induce supramolecular chirality. However, there is a lack of systematic review on this topic. This review summarizes recent studies in the constructions and applications of light-responsive chiral assembled systems, aiming to provide better knowledge for the development of multifunctional chiral nanomaterials.

Summary: This study aimed to investigate the mechanism of how a subvacuum environment promotes wound epithelisation without affecting scar hyperplasia by examining changes in cell proliferation, migration, target proteins, calcium influx, cytoskeleton, and membrane fluidity. The results showed that the subvacuum environment promoted cell migration without influencing cell proliferation, leading to increased intracellular calcium concentrations and levels of related proteins. Additionally, the cytoskeleton was depolymerized, pseudopodia were reduced or absent, and membrane fluidity increased. The use of calcium channel blockers weakened or eliminated these changes. Animal experiments confirmed these findings and demonstrated the effectiveness of subvacuum dressings in promoting wound epithelisation.
