TL;DR: A novel “smart” separator with thermal-triggered flame-retardant properties for lithium-ion batteries to improve their safety and stop the combustion of the highly flammable electrolytes.

TL;DR: This work shows a chiral branched PbSe nanowires structure, which is formed by a vapour-liquid-solid branching from a central nanowire with an axial screw dislocation, and provides a direct visualization of the Eshelby Twist.

TL;DR: A reaction-protective separator that slows the growth of lithium dendrites penetrating into the separator is produced by sandwiching silica nanoparticles between two polymer separators.

TL;DR: This work demonstrates a new approach to light management by forming whispering-gallery resonant modes inside a spherical nanoshell structure that could enable the manufacturing of high-throughput ultra-thin film absorbers in a variety of material systems that demand shorter deposition time, less material usage and transferability to flexible substrates.

TL;DR: X-ray diffraction, TEM energy dispersive X-ray spectroscopy, and galvanostatic electrochemical cycling of copper-nickel hexacyanoferrate reveal that copper and nickel form a fully miscible solution at particular sites in the framework without perturbing the structure.
