Here we propose a strategy for improving the efficiency and selectivity of nickel for electrocatalytic CO2 reduction by coating nickel nanoparticles with a thin carbon-nitrogen layer. Such a structure efficiently favors the CO desorption from catalyst surface and suppresses hydrogen production.

Pt每Zn alloy nanowires with unique zigzag-like structure and abundant high-index facets are developed for efficient alcohol electrooxidation. Alloying-induced d-band electron modulation and lattice strain effects weaken the adsorption strength of poisoning species, which intrinsically enhances the catalytic activity of Pt-Zn NWs.

The Ni12P5/CNTs hybrid was prepared via a one-step co-pyrolysis method, which exhibited a high conductivity, high surface area, firm affinity towards polysulfides and enhanced redox kinetics. The Ni12P5/CNTs-S cathode displays high rate capability and prolonged cycling stability when applied in Li-S battery.

A cross-linked polyacrylamide electrolyte by methacrylated graphene oxide (MGO-PAM) is developed to have an excellent elasticity even at -30⊥ and a higher ion conductivity (12.7 S﹞m-1) than most of polyelectrolytes previously reported. Moreover, the fabricated supercapacitors based on MGO-PAM polyelectrolyte have a highly reversible compressibility and wide temperature tolerance from -30 to 100⊥.

We report a rapid, simple, and scalable approach to fabricate DNA origami nanostructures that can be carried out on low-cost and widely available equipment such as hot plates, water baths, or even laboratory burners. We anticipate these low-cost and scalable methods can enable broader use of DNA origami and facilitate development towards biomedical and other applications.
