Low Coulombic efficiency (CE) and safety issues are huge problems that hinder the practical application of Li metal anodes. Constructing Li host structures decorated with functional species can restrain the growth of Li dendrites and alleviate the great volume change. Here, a 3D porous carbonaceous skeleton modified with rich lithiophilic groups (Zn, ZnO, and Zn(CN)2) is synthesized as a Li host via...
The growth of high‐quality halide perovskite single crystals is imperative to study their intrinsic physical properties and to realize high‐performance optoelectronic devices. Here, a room‐temperature solvent evaporation‐induced crystallization (RTSEIC) method is reported based on Le Chatelier's principle, which provides a general strategy to grow halide perovskite single crystals including 3D, 2D,...
The structural design of photocatalysts is highly related to the separation and transfer of photogenerated carriers, which is essential for the improvement of photocatalytic hydrogen evolution performance. Here, the hybrid photocatalyst M@NCNT@ZIS (M: Fe, Co, Ni; NCNT: nitrogen‐doped carbon nanotube; ZIS: ZnIn2S4) with a hierarchical structure is rationally designed and precisely synthesized. The...
Intrinsic hydrogen evolution reaction (HER) activity and the mechanism of antiperovskite Ni3In1‐xCuxN bulk cubic particles and multi‐crystalline nanoplates are thoroughly investigated. Stoichiometric Ni3In0.6Cu0.4N reaches the best HER performance, with an overpotential of 102 mV in its multi‐crystalline nanoplates obtained from the LDH‐derived method, and 143 mV in its bulk cubic particles from the...
Multi‐resonance thermally activated delayed fluorescence (MR‐TADF) material, which possesses the ability to achieve narrowband emission in organic light‐emitting diodes (OLEDs), is of significant importance for wide color gamut and high‐resolution display applications. To date, MR‐TADF material with narrow full width at half‐maximum (FWHM) below 0.14 eV still remains a great challenge. Herein, through...
The supported metal catalysts on scaffolds usually reveal multiple active sites, resulting in the occurrence of side reaction and being detrimental to the achievement of highly consistent catalysis. Single atom catalysts (SACs), possessed with highly consistent single active sites, have great potentials for overcoming such issues. Herein, the authors used SACs to modulate kinetic process of gas sensitive...
Bilayer or few‐layer 2D materials showing novel electrical properties in electronic device applications have aroused increasing interest in recent years. Obtaining a comprehensive understanding of interlayer contact conductance still remains a challenge, but is significant for improving the performance of bilayer or few‐layer 2D electronic devices. Here, conductive atomic force microscope (C‐AFM)...
Flexible electronics that can form tight interfaces with neural tissues hold great promise for improving the diagnosis and treatment of neurological disorders and advancing brain/machine interfaces. Here, the facile fabrication of a novel flexible micropillar electrode array (µPEA) is described based on a biotemplate method. The flexible and compliant µPEA can readily integrate with the soft surface...
The targeting ability, drug‐loading capacity, and size of the drug nanocarriers are crucial for enhancing the therapeutic index for cancer therapy. Herein, the morphology and size‐controllable fabrication of supramolecular tumor‐targeting nanocarriers based on host–guest recognition between a novel pillar[5]arene‐based prodrug WP5‐DOX and a Arg‐Gly‐Asp (RGD)‐modified sulfonate guest RGD‐SG is reported...
