Abstract 2D transition metal carbides and/or nitrides (MXenes), by virtue of high electrical conductivity, abundant surface functional groups and excellent dispersion in various solvents, are attracting increasing attention showing competitive performance energy storage conversion applications. However, like other materials, MXene nanosheets incline to stack together via van der Waals interactions, which lead limited number active sites, sluggish ionic kinetics, finally ordinary...
Abstract Bright and stable blue emitters with narrow full‐width at half‐maxima are particularly desirable for applications in television displays related technologies. Here, this study shows that doping aluminum (Al 3+ ) ion into CsPbBr 3 nanocrystals (NCs) using AlBr can afford lead‐halide perovskites NCs photoluminescence. First, theoretical experimental analyses reveal the extended band gap quantum confinement effect of elongated shape give rise to blueshifted emission. Second,...
Pseudocapacitors or redox capacitors that synergize the merits of batteries and double-layer are among most promising candidates for high-energy high-power energy storage applications. 2D transition metal carbides (MXenes), an emerging family pseudocapacitive materials with ultrahigh rate capability volumetric capacitance, have attracted much interest in recent years. However, MXenes only been used as negative electrodes they easily oxidized at positive (anodic) potential. To construct a...
The synthesis of crystalline two-dimensional polymers (2DPs) with proper bandgaps and well-defined repeating units presents a great challenge to synthetic chemists.

Moreover, highly function as active...
Development of new porous materials as hosts to suppress the dissolution and shuttle lithium polysulfides is beneficial for constructing highly efficient lithium-sulfur batteries (LSBs). Although 2D covalent organic frameworks (COFs) host exhibit promising potential LSBs, their performance still not satisfactory. Herein, we develop polyimide COFs (PI-COF) with a well-defined lamellar structure, which can be exfoliated into ultrathin (∼1.2 nm) nanosheets (PI-CONs) large size (∼6 μm) quantity...

Dispersion management is crucial in constructing spectrometers, superprisms, and achromatic lens systems. Unfortunately, the dispersion of natural materials determined by molecular energy levels with limited tunability, thus conventional methods controlling are complex need to trade off other aberration. Metasurface offers an alternative method overcome those limits via utilizing dedicatedly designed nanostructures that response special wavelength, which results well-engineered dispersions....
