Semiconductor core/shell quantum dots (QDs) are considered promising building blocks to fabricate photoelectrochemical (PEC) cells for the direct conversion of solar energy into hydrogen (H2). However, the lattice mismatch between core and shell in such QDs results in undesirable defects and severe carrier recombination, limiting photo‐induced carrier separation/transfer and solar‐to‐fuel conversion...
The pursuit of stable and efficient electrocatalysts toward seawater oxidation is of great interest, yet it poses considerable challenges. Herein, the utilization of Cr‐doped CoFe‐layered double hydroxide nanosheet array is reported on nickel‐foam (Cr‐CoFe‐LDH/NF) as an efficient electrocatalyst for oxygen evolution reaction in alkaline seawater. The Cr‐CoFe‐LDH/NF catalyst can achieve current densities...
Mechanically sensitive tissues (e.g., skeletal muscles) greatly need mechanical stimuli during the development and maturation. The extracellular matrix (ECM) mediates these signals through nonlinear viscoelasticity of collagen networks that are predominant components of the ECM. However, the interactions between cells and ECM form a feedback loop, and it has not yet been possible to determine the...
In this work, high‐performance epoxy resin (EP) composites with simultaneous excellent thermal conductivity (TC) and outstanding electromagnetic shielding properties are fabricated through the structural synergy of 1D carbon nanotubes and 2D silver‐modified boron nitride nanoplates (CNT/AgBNs) to erect microscopic 3D networks on long‐range carbon fiber (CF) felt skeletons. The line‐plane combination...
Dion‐Jacobson perovskite (DJP) films suffer from the high structural disorder and non‐compact morphology, leading to inefficient and unstable solar cells (SCs). Here, how the alkyl chains of alkylammonium pseudohalide additives including methylammonium thiocyanate (MASCN) and ethylammonium thiocyanate (EASCN), and propylammonium thiocyanate (PASCN), impact the microstructures, optoelectronic properties...
Sustained oral uncoupler 2,4‐dinitrophenol (DNP) administration exerts prominent anti‐obesity effects, but the adipose tissue off‐target disadvantage leads to systemic adverse effects. A novel non‐cardiotoxicity DNP delivery method using a biocompatible microneedles patch containing the amphiphilic tetradecanoic acid‐DNP ester (TADNP) is described, which is synthesized via esterification on the phenolic...
Perovskite solar cells (PSCs) based on the SnO2 electron transport layer (ETL) have achieved remarkable photovoltaic efficiency. However, the commercial SnO2 ETLs show various shortcomings. The SnO2 precursor is prone to agglomeration, resulting in poor morphology with numerous interface defects. Additionally, the open circuit voltage (Voc) would be constrained by the energy level mismatch between...
Microwave Absorption Materials
The M‐BaM@N‐reduced graphene oxide (RGO) material displays excellent microwave absorption capacity due to its mesoporous structure, in sites formed from Fe3O4 and N doped reduced graphene oxide. The synergistic effect among these nano‐micro structures realizes efficient energy conversion by weakening the incoming wave to reflected waves with lower intensity and different...
Nanocomposites with hierarchical pore structure hold great potentials for applications in the field of microwave‐absorbing materials because of their lightweight and high‐efficiency absorption properties. Herein, M‐type barium ferrite (BaM) with ordered mesoporous structure (M‐BaM) is prepared via a sol–gel process enhanced by mixed anionic and cationic surfactants. The surface area of M‐BaM is enhanced...
