Designing superb dielectric capacitors is valuable but challenging since achieving simultaneously large energy‐storage (ES) density and high efficiency is difficult. Herein, the synergistic effect of grain refining, bandgap widening, and domain engineering is proposed to boost comprehensive ES properties by incorporating CaTiO3 into 0.92NaNbO3‐0.08BiNi0.67Ta0.33O3 matrix (as abbreviated NN‐BNT‐xCT)...
Recently, 2D materials are in great demand for various applications such as optical devices, supercapacitors, sensors, and biomedicine. MXenes as a kind of novel 2D material have attracted considerable research interest due to their outstanding mechanical, thermal, electrical, and optical properties. Especially, the excellent nonlinear optical response enables them to be potential candidates for the...
MXenes as a kind of novel 2D transition metal carbon and/or nitrogen materials are commonly prepared by etching A‐group elements (mostly groups 13 or 14) from MAX phases. Owing to the excellent optical properties, MXenes have been widely used to realize ultrafast pulses in different lasers. In article number 2006054, Jiebo Li, Han Zhang, and co‐workers review the state of the art of MXenes, where...
In article number 2005925, Xian Huang and co‐workers develop a multi‐channel flexible optoelectronic fiber device that consists of flexible fibers, flexible microelectrode arrays, and a miniaturized wireless circuit. The combined configuration of optical fibers and flexible electronics allows optical stimulation in selective wavelengths guided by the optical fibers, while conducting distributed, high‐throughput...
Optical fibers made of polymeric materials possess high flexibility that can potentially integrate with flexible electronic devices to realize complex functions in biology and neurology. Here, a multichannel flexible device based on four individually addressable optical fibers transfer‐printed with flexible electronic components and controlled by a wireless circuit is developed. The resulting device...
Tumor vasculature and cancer stem cells (CSCs) accelerate the development of metastatic renal cancer. Dual inhibition of vascular endothelium and CSCs is still a challenge due to their different pathological features. Herein, a transformable dual‐inhibition system (TDS) based on a self‐assembly peptide is proposed to construct nanofibrous barriers on the cell membrane in situ, which contributes to...
In article number 2004548, Lei Wang, Ziqi Wang, Hao Wang, Wanhai Xu, and co‐workers propose a transformable dual‐inhibition system (TDS) based on a self‐assembly peptide to reduce metastasis of renal cancer via the inhibition of neovascular endothelial cells and cancer stem cells simultaneously. The TDS has great value in suppressing renal cancer metastasis. Additionally, this newly developed TDS...
