Aqueous zinc-metal batteries have attracted extensive attention due to their outstanding merits of high safety and low cost. However, the intrinsic thermodynamic instability zinc in aqueous electrolyte inevitably results hydrogen evolution, consequent generation OH- at interface will dramatically exacerbate formation dead dendrites. Herein, a dynamically interfacial pH-buffering strategy implemented by N-methylimidazole (NMI) additive is proposed remove detrimental zinc/electrolyte...

Uncontrolled dendrite growth and worse side reactions shorten the life span of aqueous zinc energy storage devices limit their practical application. Herein, we report for first time a high-performance lignocellulosic gel polymer electrolyte (LC-GPAE) with abundant polar functional groups. The strong interaction between Zn2+ groups inside LC-GPAE can weaken solvation water, thus reducing desolvation activation [Zn(H2O)6]2+ improving kinetics in stripping/plating process. It is mainly...

Stable metal-organic frameworks (MOFs) with mesopores (2-50 nm) are promising platforms for immobilizing nanosized functional compounds, such as metal-oxo clusters, metal-sulfide quantum dots, and coordination complexes. However, these species easily decompose under acidic conditions or high temperatures, hindering their in situ encapsulation stable MOFs, which usually synthesized harsh involving excess acid modulators temperatures. Herein, we report a route the room-temperature...

Electrolyte additives have been widely studied in the improvement of stability aqueous electrolytes. Here, we report a crosslinking cotton fiber-/PVA-based membrane (CPM) with an excellent porosity 73.82% and ultrahigh liquid electrolyte uptake 900 wt %, prepared by solution casting method. Li2SO4 as salt various concentrations Al3+ were used for fabricating gel polymer (GPE). On adding into electrolyte, dissociative water bound Li+ solvation interact Al3+; this affects molecule activity...

The α-amylase and α-glucosidase inhibitory effects of Ligustrum robustum (Rxob.) Blume extract (LRE) were investigated the primary bioactive components isolated identified. With high contents phenols flavonoids, LRE exhibited remarkable on α-glucosidase. It also displayed strong antioxidant activity for scavenging free radicals (superoxide hydroxyl radicals), inhibiting lipid peroxidation providing reducing power. Moreover, effectively inhibited catalytic sucrase maltase in Caco-2 cell...

Cyclohexanone monooxygenases (CHMOs) show very high catalytic specificity for natural Baeyer-Villiger (BV) reactions and promiscuous reduction have not been reported to date. Wild-type CHMO from Acinetobacter sp. NCIMB 9871 was found possess an innate, ability reduce aromatic α-keto ester, but with poor yield stereoselectivity. Structure-guided, site-directed mutagenesis drastically improved the carbonyl-reduction activity (yield up 99 %) stereoselectivity (ee %), thereby converting this...
