A flexible and transparent triboelectric nanogenerator (FT-TENG), with an ordered porous polydimethylsiloxane (PDMS) film and graphene electrodes is fabricated. The ordered porous PDMS film with high transmittance is fabricated by acid etching ZnO spheres composed of aggregated nanoparticle. The output performance of the FT-TENG, based on the ordered porous film, is greatly improved with little damage to its optical properties. The effects of the microstructure formed in a dielectric tribomaterial, on the surface charge density are systematically analyzed.

A novel SeS2/double-layered hollow carbon composite was designed where SeS2 is located predominantly in the interlayer void of the double-layered structures with a high loading of 75%. The asprepared composite exhibits high reversible specific capacity, good cycling stability, and excellent rate capability as a cathode material for Li–SeS2 batteries.

A lightweight, electrically conductive hybrid carbon aerogel with both aligned micrometer-sized and interconnected nanometer-sized pores was created as a promising interlayer for lithium–sulfur battery. The hierarchically porous structure promotes transport of electrons and lithium ions and efficiently mitigates “shuttling” of the polysulfides. The resulting lithium–sulfur battery exhibits combined high specific capacity, rate capability, and cycling stability.

The Janus polymer multilayer capsule motor can perform fuel-free propulsion under exposure to near-infrared light in various fluids. Such near-infrared-powered propulsion relies on the self-thermophoresis of Janus capsule motors through the photothermal effect.

In this paper, we report the designed synthesis of micron-sized, highly ordered mesoporous microspheres comprising few-layered graphene, which are demonstrated to be an ideal platform for fabricating high-performance composite electrodes to be used in lithium-ion batteries.

Three-dimensional rosebud-like MoSe2@rGO hybrid nanostructures with good electrocatalytic activity for the oxygen reduction reaction (ORR) were successfully synthesized. The scanning electrochemical microscopy technique was used to investigate the local electrocatalytic activity of the MoSe2@rGO composites for the ORR at the micrometer scale.

Polyhedral lead sulfide (PbS) nanocrystals with exposed {100} and {111} facets show {100}-facet-dependent toxicity through activation of oxidative stress and heavy metal stress responses. Toxicity was induced by {100}-facet-dependent Pb dissolution, and NH4Cl-based surface passivation was developed as an efficient “safe-by-design” approach to prevent Pb dissolution from {100} facets and create safer polyhedral PbS nanocrystals.
