The change of 3D spatial distribution of magnetic permeability can lead to the generation of introduced electrical signals. However, present studies can only achieve rough regulation by simple shape deformation of magnetic elastomers such as compression, bending, or stretching. Accurate control of the 3D spatial distribution of magnetic permeability is still an open question. In this study, an on‐demand...
The global pandemic and excessive use of antibiotics have raised concerns about environmental health, and efforts are being made to develop alternative bactericidal agents for disinfection. Metal‐based nanomaterials and their derivatives have emerged as promising candidates for antibacterial agents due to their broad‐spectrum antibacterial activity, environmental friendliness, and excellent biocompatibility...
Synaptic devices that mimic biological synapses are considered as promising candidates for brain‐inspired devices, offering the functionalities in neuromorphic computing. However, modulation of emerging optoelectronic synaptic devices has rarely been reported. Herein, a semiconductive ternary hybrid heterostructure is prepared with a D‐D’‐A configuration by introducing polyoxometalate (POM) as an...
In this work, high‐performance, light‐stimulation healable, and closed‐loop recyclable covalent adaptable networks are successfully synthesized from natural lignin‐based polyurethane (LPU) Zn2+ coordination structures (LPUxZy). Using an optimized LPU (LPU‐20 with a tensile strength of 28.4 ± 3.5 MPa) as the matrix for Zn2+ coordination, LPUs with covalent adaptable coordination networks are obtained...
GaN‐based lateral Schottky barrier diodes (SBDs) have attracted great attention for high‐power applications due to its combined high electron mobility and large critical breakdown field. However, the breakdown voltage (BV) of the SBDs are far from exploiting the material advantages of GaN at present, limiting the desire to use GaN for ultra‐high voltage (UHV) applications. Then, a golden question...

GaN is a promising candidate for next‐generation power electronic devices, but its potential is far from being realized. In article number 2107301, Peng Chen, Rong Zhang, Youdou Zheng, and co‐workers demonstrate a high power figure‐of‐merit, 10.6‐kV AlGaN/GaN lateral Schottky barrier diode with single channel, and sub‐100‐μm anode‐to‐cathode spacing without any other additional...
A facile multistage regulated strategy is reported to synthesize ZnCo‐NC based carbon nanotubes including DMEA induced crystallization, Zn ion activation, and magnetic control growth of carbon nanotubes. Uniform Co distribution and the modulation of Zn, and their catalytic properties are carefully investigated by X‐ray absorption spectroscopy and X‐ray photoelectron spectroscopy. The surface contents...
The specific coagulation in the tumor vasculature has the potential for the ablation of solid tumors by cutting off the blood supply. However, the safe delivery of effective vessel occluding agents in the tumor‐specific embolization therapy remains challenging. Herein, it is reported that the photothermal responsive tumor‐specific embolization therapy based on thrombin (Thr) is delivered by intravenous...
Ionometallurgy is a new development aiming at the sustainable low‐temperature conversion of naturally occurring metal ores and minerals to their metals or valuable chemicals in ionic liquids (ILs) or deep eutectic solvents. The IL betainium bis((trifluoromethyl)sulfonyl)imide, [Hbet][NTf2], is especially suited for this process due to its redox‐stability and specific‐functionalization. The potentiostatic...
2D non‐layered materials (2DNLMs) featuring massive undercoordinated surface atoms and obvious lattice distortion have shown great promise in catalytic/electrocatalytic applications, but their controllable synthesis remains challenging. Here, a new type of ultrathin carbon‐wrapped titanium nitride nanomesh (TiN NM@C) is prepared using a rationally designed nano‐confinement topochemical conversion...
The organic–inorganic hybrid perovskite solar cells present a rapid improvement on power conversion efficiency from 3.8% to 25.5% in the past decades. Owing to the tuneable bandgaps, low‐cost, and ease of fabrication, perovskites become ideal candidate materials for fabricating tandem solar cells, especially for efficient and high‐voltage monolithic two‐terminal devices. In this review, an overview...
Recently, all‐inorganic halide perovskite (CsPbX3, (X = Cl, Br, and I)) nanocrystals (NCs) based hybrid architectures have attracted extensive attention owing to their distinct luminescence characteristics. However, due to stress and lattice mismatch, it is still a challenge to construct heterojunctions between perovskite NCs and the nanostructures with different lattice parameters and non‐cubic contour...
Obesity is a serious epidemic health problem that can cause many other diseases including type 2 diabetes and cardiovascular diseases. Current approaches to combat obesity suffer from low effectiveness and adverse side effects. Here, a new self‐administrable and minimally invasive transdermal drug delivery strategy for home‐based long‐term treatment of obesity and other diseases is developed. Specifically,...
Hypoxia severely impedes photodynamic therapy (PDT) efficiency. Worse still, considerable tumor metastasis will occur after PDT. Herein, an organic superoxide radical (O2∙−) nano‐photogenerator as a highly effcient type I photosensitizer with robust vascular‐disrupting efficiency to combat these thorny issues is designed. Boron difluoride dipyrromethene (BODIPY)‐vadimezan conjugate (BDPVDA) is synthesized...

Plasmonic nanolasers based on wide bandgap semiconductors are presently attracting immense research interests due to the breaking in light diffraction limit and subwavelength mode operation with fast dynamics. However, these plasmonic nanolasers have so far been mostly realized in the visible light ranges, or most are still under optical excitation pumping. In this work, III‐nitride‐based plasmonic...
