Elastic Organic Crystals Based on Barbituric Derivative: Multi-faceted Bending and Flexible Optical Waveguide.

Elastic organic single crystals with light-emitting and multi-faceted bending properties are extremely rare. They have potential application in optical materials and have attracted the extensive attention of researchers. In this paper, we reported a structurally simple barbituric derivative DBDT, which was easily crystallized and gained long needle-like crystals (centimeter-scale) in DCM/CH OH (v/v=2/8).

Rapid Fabrication of Ni/NiO@CoFe Layered Double Hydroxide Hierarchical Nanostructures by Femtosecond Laser Ablation and Electrodeposition for Efficient Overall Water Splitting.

The development of simple and effective methods for the rapid preparation of electrocatalysts for overall water splitting from earth-abundant elements is an important and challenging task. A facile and ultrafast two-step method was developed to prepare a Ni/NiO@CoFe layered double hydroxide hierarchical nanostructure (NCF) within a few minutes by femtosecond laser ablation and electrodeposition. In 1 m KOH solution, the optimized NCF catalysts show a low overpotential of 230 mV for the oxygen evolution reaction (OER) at a current density of 10 mA cm with a low Tafel slope of 34.

Controllable Synthesis of Marks Decahedral Pd Nanoparticles via Etching.

Marks decahedral nanoparticles have attracted significant attention in recent years. In this work, a method of synthesizing Marks decahedron via etching regular decahedral nanoparticles is proposed and verified by Pd nanoparticles, which shows a high yield of Marks decahedron. The present work suggests that one can tune the concave size of Marks decahedral via controlling the etching time and the amount of Poly(vinyl pyrrolidone) (PVP).

One-pot synthesis of CuPt nanodendrites with enhanced activity towards methanol oxidation reaction.

CuPt nanodendrites have special electrocatalytic performance due to their unique morphologies and structures. In this work, we report a facile and one-pot synthesis of highly branched and dispersed CuPt nanodendrites with a size of about 22 nm and Pt/Cu ratio of 2 : 1. X-ray photoelectron spectra indicate a Pt-rich surface of the prepared CuPt nanodendrites.
