Prussian-Blue Analogue-Derived Hollow Structured Co S /CuS /NiS Nanocubes as an Advanced Battery-Type Electrode Material for High-Performance Hybrid Supercapacitors.

The facile and cost-effective fabrication of hybrid nanostructures comprised of hollow mixed metallic chalcogenides has attracted growing interest in the development of high-performance energy storage devices. Herein, multi-component (nickel-cobalt-copper-sulfides/selenides (NCCS/NCCSe)) hollow nanocubes (HNCs) are prepared via a single-step sulfurization/selenization process. The NCCS material shows interior HNCs, and the NCCSe material exhibits slightly formed porous cubes.

Enhanced Performance of Microarchitectured PTFE-Based Triboelectric Nanogenerator via Simple Thermal Imprinting Lithography for Self-Powered Electronics.

Triboelectric nanogenerator (TENG) technology is an emerging field to harvest various kinds of mechanical energies available in our living environment. Nowadays, for industrial and large-scale area applications, developing the TENG with low device processing cost and high electrical output is a major issue to be resolved. Herein, we designed a TENG with low cost by employing the microgrooved architectured (MGA)-poly(tetrafluoroethylene) (PTFE; Teflon) and aluminum as triboelectric materials with opposite tendencies.
