A 3D network gel polymer electrolyte (3D-GPE) is designed for lithium metal batteries and prepared by an initiator-free one-pot ring-opening polymerization technique. This 3D-GPE exhibits unprecedented combination of mechanical strength, ionic conductivity, more importantly, effective suppression Li dendrite growth. The produced lithium-based battery presents long life, high rate, excellent safety.

Metal-organic frameworks (MOFs) have attracted much attention in the areas of biomedicine and medicine owing to their versatile porous structure. However, oversize high cellular toxicity some metal-based MOF particles hindered development. Therefore, a series small Ti-based MOFs are prepared with introduction tetraethyl orthosilicate (TEOS) into reaction system. Compared by traditional methods, size this method is decreased 42.78%. Meanwhile, good biocompatibility toward L929 cell lines...

The Lewis acid-base reaction between PbI2 and solvent molecules is popular in fabricating films by a two-step method for making perovskite solar cells. Here, we control the microstructure of through modulating adding small amount N-methyl pyrrolidone into PbI2/DMF solution. with excellent crystallinity full coverage are fabricated spin-coating mixed solution on substrate, which leads to high quality layers low recombination rate efficiency carrier transfer. As result, power conversion best...

Abstract Efficient detection of aqueous copper ions is high significance for environmental and human health, since involved in potent redox activity physiological pathological processes. Covalent organic frameworks (COFs) have shown advantages efficient capturing detecting due to their large surface area, robust chemical stability, sensitivity, but most them are hydrophobic, leading the limitation sensing media. Herein, design synthesis an sp 2 ‐carbon conjugated COF (sp ‐TPE‐COF) reported...

A novel method for the selective fluorescence sensing of Hg2+ and Zn2+ ions via dual independent channels was reported, based on site-specific functionalization mesoporous silica nanoparticles (MSN). Taking advantage distinctive co-condensation post-grafting process different organoalkoxysilanes, amine azide functionalities were covalently attached to inner outer surfaces MSN, respectively. The incorporation rhodamine B-based (RhBHA) quinoline-based (CQA) ion sensors then achieved...

High-quality perovskite films can be fabricated from Lewis acid–base adducts through molecule exchange. Substantial work is needed to fully understand the formation mechanism of films, which helps further improve their quality. Here, we study CH3NH3PbI3 by introducing some dimethylacetamide into PbI2/N,N-dimethylformamide solution. We reveal that there are three key processes during adduct approach: intercalation solvent PbI2 lattice, exchange between and CH3NH3I,...

ABSTRACT Poly(ethylene oxide) (PEO) nanofibers were prepared by electrospinning PEO solution with a mixed solvent of ethanol and deionized water. The results show that the system has noteworthy influences on structures properties electrospun nanofibers, including molecular chain orientation, crystallinity degree, surface morphology, fiber diameter, diameter distribution, spinnability, productivity. With increasing content in solvent, wrinkly morphologies appear due to high evaporation rate...

Bismuth oxide is one of the best-known formate production catalysts from electrocatalytic reduction CO2. It came as a surprise here that its hybridization with CeOx drastically boosted catalytic activity and stability on CO2 toward formation. Specifically, faradaic efficiency Bi2O3–CeOx exceeds 85% starting −0.3 V vs reversible hydrogen electrode (RHE) remains above 90% −0.5 to −1.1 RHE, outperforming pure Bi2O3 most other reported catalysts. Experimental computational results suggest...

Abstract In this study, three phenylimidazole ( pmi )‐based asymmetric iridium(III) complexes are successfully developed as promising emitters for non‐doped blue organic light emitting diodes (OLEDs). The Ir‐3 exhibited emission with peak located at 470 nm and a high photoluminescent quantum yield (Φ PL ) of 65% in film. Single crystal X‐ray diffraction analysis revealeds that has increased steric hindrance from bulky tert‐butyl groups effectively suppressed π – stacking minimized exciton...
