The controlled synthesis of Cu(OH)2 nanowires and nanoribbons in a solution phase has been realized with high yield at low cost by simply dropping KOH ammonia solutions into an aqueous CuSO4 ambient temperature. It is demonstrated that the morphology nanostructured significantly influenced feeding manner alkaline solutions.

Abstract Periodic wrinkling across different scales has received considerable attention because it not only represents structure failure but also finds wide applications. How to prevent or create desired patterns is non‐trivial the dynamic evolution of wrinkles a highly nonlinear problem.

The light‐induced photoisomerization azobenzene units in azopolymer films leads stress release and consequently...
Pressure sensors have a variety of applications including wearable devices and electronic skins. To satisfy the practical applications, pressure with high sensitivity, low detection limit, low-cost preparation are extremely needed. Herein, we fabricate highly sensitive based on hierarchically patterned polypyrrole (PPy) films, which composed three-scale nested surface wrinkling microstructures through simple process. Namely, double-scale wrinkles generated via in situ self-wrinkling during...

Herein, highly sensitive piezoresistive pressure are reported with novel light‐boosting sensing performances. Rose...
Abstract 3D printing graphene aerogel with periodic microlattices has great prospects for various practical applications due to their low density, large surface area, high porosity, excellent electrical conductivity, good elasticity, and designed lattice structures. However, the specific capacitance limits development in energy storage fields stacking of graphene. Therefore, constructing a graphene‐based 2D materials hybridization that consists pseduocapacitive substance material is...
