Built‐In Electric Field in 2D/2D LDH/Antimonene Heterostructure to Induce Stable β‐NiOOH at Ultralow Potential for Cost‐Effective Water Electrolysis

Advanced Functional Materials, EarlyView.
In this paper, a built‐in electric field (BEF) strategy is proposed to fabricate NiFe‐LDH/antimonene heterostructure as bifunctional electrocatalysts for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). The formed BEF generates a local potential that reduces the potential for the formation of β‐NiOOH, thereby enabling ultra‐low ...

Resolution of desmosterol, cholesterol, and other sterol intermediates by reverse-phase high-pressure liquid chromatography.

Journal of Lipid Research, 1978
A highly efficient technique has been developed for the resolution of several sterols that are intermediates in the biosynthesis of cholesterol and that differ only by one carbon-carbon double bond or by one methyl group. The technique described utilizes

Copper Doping Enhances the Activity and Selectivity of Atomically Precise Ag44 Nanoclusters for Photocatalytic CO2 Reduction

Advanced Functional Materials, EarlyView.
By a simple anti‐Galvanic reaction, up to six copper atoms could be preferably doped into the Ag2(SR)5 staple motifs and Ag20 dodecahedral shell of an atomically precise Ag44(SR)30 nanocluster. When anatase TiO2 is used as substrate, the (AgCu)44/TiO2 photocatalyst exhibited much improved activity in photocatalytic CO2 reduction compared to Ag44/TiO2 ...

Rotating Liquid Marble Microreactors for Enhanced Enzymatic Reactions

Advanced Functional Materials, EarlyView.
Dynamic magnetic liquid marbles (LMs), stabilized by hydrophobic magnetic proteinaceous colloidosomes, function as effective microreactors for enzymatic processes. Precise magnetic manipulation allows for the rotation of these LMs, enhancing the efficiency of the enzymatic cascade reaction both at the air/water interface and within biphasic enzyme ...

Native Lignin Migration and Clustering in Wood: Superhydrophobic, Antimold, and Tribonegative Layers for Rain‐Driven Electrification

Advanced Functional Materials, EarlyView.
This study proposes a sustainable solution for rainwater‐driven energy harvesting by harnessing the intrinsic properties of lignin in wood. The first demonstration of an all‐wood tribonegative material for liquid–solid triboelectric nanogenerators is presented, eliminating the need for fluorine‐containing polymers and functional additives. Abstract The

A Sustainable Biotechnology Approach for Mineral Separation

Advanced Functional Materials, EarlyView.
Silver‑binding peptides are first identified through phage‐display screening, and then engineered into multifunctional and responsive peptides or proteins. These tailored biomolecules can selectively capture and aggregate silver particles or ions from complex mixtures, enabling rapid and efficient silver separation and recovery.

Harnessing Interfacial Cl− Ions for Concurrent Formate Production at Industrial Level via CO2 Reduction and Methanol Oxidation

Advanced Functional Materials, EarlyView.
The replacement of the anodic OER in CO2RR with energy‐saving methanol oxidation reaction and the creation of a favorable microenvironment through interfacial Cl− ions enable concurrent formate production at industrial‐level current densities. Abstract The efficient electrocatalytic conversion of CO2 to formate is often impeded by the high energy ...
