TL;DR: Porous urchin-like MnCo2O4.5 hierarchical architectures synthesized by a facile hydrothermal route followed by a calcination process exhibited a specific capacitance of 151.2 F g−1 at 5 mV s−1 as discussed by the authors.
Abstract: Porous urchin-like MnCo2O4.5 hierarchical architectures (~4–6 μm in diameter) synthesized by a facile hydrothermal route followed by a calcination process exhibited a specific capacitance of 151.2 F g−1 at 5 mV s−1, outstanding rate capability with 83.6% specific capacitance retention even when the current density is increased 50 times and excellent long-term cycle stability at progressively varied current densities and could be considered as a potential mixed transition metal oxide material for high-rate supercapacitors in some special applications that do not require a high capacitance.

TL;DR: A novel synthesized fluorinated polyurethane (FPU) modified nanofibrous membrane optimized to achieve oil and non-oil aerosol particle filtration and can capture, for the first time, a range of different oil aerosol particles in a single-unit operation, with >99.9% filTration efficiency.
Abstract: The worldwide demands are rising for an energy-efficient and cost-effective approach that can provide advanced nanofibrous membranes with high filtration performance and superior antifouling properties. Here we report a novel synthesized fluorinated polyurethane (FPU) modified nanofibrous membrane optimized to achieve oil and non-oil aerosol particle filtration. By employing the FPU incorporation, the polyacrylonitrile/polyurethane (PAN/PU) composite membranes were endowed with superhydrophobicity with a water contact angle of 154° and superoleophobicity with an oil contact angle of 151°. Morphology, surface wettability, porous structure, and filtration performance could be manipulated by tuning the solution composition as well as the hierarchical structure. Furthermore, the as-prepared membranes can capture, for the first time, a range of different oil aerosol particles in a single-unit operation, with >99.9% filtration efficiency, by using the combined contribution of fiber diameter and surface roughness acting on the objective particles. Exemplified here by the construction of superamphiphobic nanofibrous membrane, numerous applications of this medium includes high efficiency particulate air filters, ultra-low penetration air filters, and respiratory protection equipment.

TL;DR: The as-obtained V5S8@C electrode enables rapid and reversible storage of K+ with a high specific capacity, high rate capability, and long cycling stability, and the excellent electrochemical performance is superior to the most existing electrode materials.
Abstract: Due to the abundant potassium resource on the Earth’s crust, researchers now have become interested in exploring high-performance potassium-ion batteries (KIBs). However, the large size of K+ would...

TL;DR: Under visible-light photoredox conditions, difluoromethyltriphenylphosphonium bromide was used as the precursor of the CF2H radical for bromodiflu oromethylation of alkenes and the presence of catalytic CuBr2 resulted in the selective formation of the bromodelectric products.
