The interaction between catalyst and support plays an important role in electrocatalytic hydrogen evolution (HER), which may explain the improvement in performance by phase transition or structural remodeling. However, the intrinsic behavior of these catalysts (dynamic evolution of the interface under bias, structural/morphological transformation, stability) has not been clearly monitored, while the...
A 3D crimped sulfonated polyethersulfone‐polyethylene oxide(C‐SPES/PEO) nanofiber membrane and long‐range lanthanum cobaltate(LaCoO3) nanowires are collectively doped into a PEO matrix to acquire a composite solid electrolyte (C‐SPES‐PEO‐LaCoO3) for all‐solid‐state lithium metal batteries(ASSLMBs). The 3D crimped structure enables the fiber membrane to have a large porosity of 90%. Therefore, under...
Carbon materials are widely accepted as promising candidates for sodium‐ion batteries (SIBs) anodes due to their chemical stability and conductivity, while the capacity is still unsatisfactory. Here, this work reports the superhigh capacity Na storage through initiating fluorine chemistry (CF bonds) in carbon synthesized by the dehydrogenation and fluorination of polycyclic aromatic hydrocarbon such...
The interface plays a pivotal role in stabilizing metal anode. Extensive studies have been made but systematic research is lacking. In this study, preliminary studies are conducted to explore the prime conditions of interfacial modification to approach the practical requirements. Critical factors including reaction kinetics, transport rate, and modulus are identified to affect the Zn anode morphology...
Constructing ionic conductive hydrogels with diversified properties is crucial for portable zinc‐ion hybrid supercapacitors (ZHSCs). Herein, a freeze‐tolerant hydrogel electrolyte (AF PVA‐CMC/Zn(CF3SO3)2) is developed by forming a semi‐interpenetrating anti‐freezing polyvinyl alcohol‐carboxymethyl cellulose (AF PVA‐CMC) network filled with the ethylene glycol (EG)‐containing Zn(CF3SO3)2 aqueous solution...
Metal–organic framework (MOF)‐derived heterostructures possessing the merits of each component are thought to display the enhanced energy storage performance due to their synergistic effect. Herein, a functional heterostructure (NiCoP–MOF) composed of nickel/cobalt‐MOF (NiCo–MOF) and phosphide (NiCoP) is designed and fabricated via the localized phosphorization of unusual lamellar brick‐stacked NiCo–MOF...
Different from graphene with the highly stable sp2‐hybridized carbon atoms, which shows poor controllability for constructing strong interactions between graphene and guest metal, graphdiyne has a great potential to be engineered because its high‐reactive acetylene linkages can effectively chelate metal atoms. Herein, a hydrogen‐substituted graphdiyne (HsGDY) supported metal catalyst system through...
There is a growing demand for flexible and wearable energy devices. How to enhance their tolerance to various mechanical stresses is a key issue. Bending, stretching, or twisting of flexible batteries has been widely researched. However, shear force is inevitably applied on the batteries during stretching, bending, and twisting. Unfortunately, thus far, research on analyzing shear resistance of solid...
Chiral properties of nanoscale materials are of importance as they dominate interactions with proteins in physiological environments; however, they have rarely been investigated. In this study, a systematic investigation is conducted for the adsorption behaviors of bovine serum albumin (BSA) onto the chiral surfaces of gold nanoparticles (AuNPs), involving multiple techniques and molecular dynamic...
Ligand‐free negatively charged magnetic nanoclusters are first presented for effective structure‐selective protein adsorption by F. Lan, Z. Gu and co‐workers on page 2344. The nanoclusters could selectively capture bovine hemoglobin as well as structurally similar proteins (e.g., lysozyme, chymotrypsin) from model proteins and even biological samples due to their highly negative charge, exhibiting...
The easy and effective capture of a single protein from a complex mixture is of great significance in proteomics and diagnostics. However, adsorbing nanomaterials are commonly decorated with specific ligands through a complicated and arduous process. Fe3O4/carboxymethylated chitosan (Fe3O4/CMCS) nanoclusters are developed as a new nonligand modified strategy to selectively capture bovine hemoglogin...
