Abstract Hierarchical flowerlike nickel hydroxide decorated on graphene sheets has been prepared by a facile and cost‐effective microwave‐assisted method. In order to achieve high energy power densities, high‐voltage asymmetric supercapacitor is successfully fabricated using Ni(OH) 2 /graphene porous as the positive negative electrodes, respectively. Because of their unique structure, both these materials exhibit excellent electrochemical performances. The optimized could be cycled...
Significance A series of metal sulfides were systematically investigated as polar hosts to reveal the key parameters correlated energy barriers and polysulfide adsorption capability in Li−S batteries. The investigation demonstrates that catalyzing oxidation is critical reducing barrier contributing remarkably improved battery performance. Density functional theory simulation allows us identify mechanism for how binding polysulfides trapping dominate Li 2 S decomposition process overall...
Here, we developed high-efficiency (>99.5%) polyimide-nanofiber air filters for the high temperature PM2.5 removal. The polyimide nanofibers exhibited thermal stability, and removal efficiency was kept unchanged when ranged from 25-370 °C. These had flux with very low pressure drop. They could continuously work >120 h index >300. A field-test showed that they effectively remove >99.5% PM particles car exhaust at temperature.

The Schulz-Flory distribution is a mathematical function that describes the relative ratios of polymers different length after polymerization process, based on their probabilities occurrence. Carbon nanotubes (CNTs) are big carbon molecules which have very high length-to-diameter ratio, somewhat similar to polymer molecules.

Abstract The traditional Zn/MnO 2 battery has attracted great interest due to its low cost, high safety, output voltage, and environmental friendliness. However, it remains a big challenge achieve long‐term stability, mainly owing the poor reversibility of cathode reaction. Different from previous studies where redox reaction MnO /MnOOH is in solid state with limited reversibility, here new aqueous rechargeable flow constructed dissolution–precipitation reactions both cathodes (Mn 2+ /MnO )...
Fatigue resistance is a key property of the service lifetime structural materials. Carbon nanotubes (CNTs) are one strongest materials ever discovered, but measuring their fatigue challenge because size and lack effective measurement methods for such small samples.

Radiative cooling is a zero-energy technology that enables subambient by emitting heat into outer space (~3 K) through the atmospheric transparent windows. However, existing designs typically focus only on main window (8-13 μm) and ignore another (16-25 μm), under-exploiting their potential. Here, we show dual-selective radiative design based scalable thermal emitter, which exhibits selective emission in both windows reflection remaining mid-infrared solar wavebands. As result, emitter an...
