Advanced materials for electrocatalytic water splitting are central to renewable energy research. In this study, we describe a two-step reaction for preparing hydrogen evolution reaction (HER) electrodes composed of Pt nanoparticles and MoS 2 nanosheets grown on carbon fibers. The morphology and the structures are characterized by a variety of techniques(More)
We developed a novel micro-droplet array system, which is based on the distinct three dimensional mesh screen structure and sintering and oxidation induced thermal-fluid performance. Mesh screen was sintered on a copper substrate by bonding the two components. Non-uniform residue stress is generated along weft wires, with larger stress on weft wire top(More)
The working of nonaqueous Li-O2 batteries relies on the reversible formation/decomposition of Li2O2 which is electrically insulating and reactive with carbon and electrolyte. Realizing controlled growth of Li2O2 is a prerequisite for high performance of Li-O2 batteries. In this work, a sandwich-structured catalytic cathode is designed:(More)
A sandwich structured Bi 2 Te 3-nanoplates/graphene-nanosheet (Bi 2 Te 3 /G) hybrid has been synthesized by a facile in situ solvothermal route and has been investigated as a potential anode material for Li-ion batteries. Bi 2 Te 3 grows during the solvothermal process with the simultaneous reduction of graphite oxide into graphene. The in situ formation(More)
