Choi, R. Kwak, and co-workers in article number 1601725. ColloidsNovel monodispersed polysulfide spheres with intrinsic high refractive index and light absorbing characteristics are designed and synthesized by B. T. Tang and co-workers in article number 1602565.The monodispersed polysulfide spheres are used to fabricate 3D ordered photonic crystals through a colloidal assembly method.Multiple bioinspired structural colors with high color visibility and broad viewing angle are achieved. Silicon-Sulfur BatteriesA novel lithiated silicon-sulfur battery is presented by B. Li, F. Kang, and co-workers in article number 1602015.A solid-like electrolyte fabricated by integrating a silicon oxide hollow nanosphere layer and ether-based electrolyte with a fluoroethylene carbonate additive was exploited.The prepared battery exhibited enhanced cycle life, low flammability, and strong recovery ability against short-circuits.
