This paper describes a strategy for preparing free-standing reduced graphene oxide@Si nanoparticles (rGO@Si NPs) composite membranes. Graphene oxide (GO) was and self-assembled synchronously with of silicon (Si on metal surface the film subsequently used in lithium-ion battery (LIB). work several important novel aspects reported technology. Firstly, membrane has flexible self-supporting structu...

The group 5-7 transition metal oxides (V2O5, CrO3, MoO3, WO3, and Re2O7) were anchored on a surface modified SiO2 support containing surface alumina, zirconia, and titania species prepared via incipient wetness impregnation of soluble precursors and calcination. The molecular and electronic structures of these “multilayered” supported M1Ox/M2Ox/SiO2 catalysts were characterized with in situ Ram...

Transition metal oxides display various electronic and magnetic phases such as high-temperature superconductivity. Controlling such exotic properties by applying an external field is one of the biggest continuous challenges in condensed matter physics. Here, we demonstrate clear superconductor-insulator transition of LiTi2O4 films induced by Li-ion electrochemical reaction. A compact electroche...

Microbial electrolysis cell (MEC) is a gripping bio-electrochemical device producing H2 gas from renewable biomass while at the same time treat wastewater.  Through extensive global research efforts in the latest decade, the performance of MECs, including energy efficiency, hydrogen production rate (HPR), and hydrogen recovery have achieved significant breakthroughs. However, employi...

The magnesium-metal battery, which consists of a cathode, a Mg-metal anode, and a nonaqueous electrolyte, is a safer and less expensive alternative to the popular Li-ion battery. However, the performance of Mg batteries is greatly limited by the low electrochemical oxidative stability of nonaqueous electrolytes, the slow Mg diffusion into the cathode, and the irreversibility of Mg striping and ...

Two-dimensional electron gases (2DEGs) forming at the interfaces of transition metal oxides exhibit a range of properties, including tunable insulator-superconductor-metal transitions, large magnetoresistance, coexisting ferromagnetism and superconductivity, and a spin splitting of a few meV (refs 10, 11). Strontium titanate (SrTiO3), the cornerstone of such oxide-based electronics, is a transp...
