Graphene nanocomposites have attracted much attention in many applications due to their superior properties. However, preparing graphene requires a time-consuming thermal treatment reduce the or synthesize nanomaterials, most cases. We present an ultrafast synthesis of carbon-coated silicon-graphene nanocomposite using commercial microwave system. Electrochemically exfoliated is used as novel susceptor deliver efficient energy conversion. Unlike oxide, it does not require pre-thermal...

The translucent white-coloured, Gram-stain-negative, aerobic, non-motile, fusiform-shaped bacterium (designated strain SY72T) was isolated from waste-activated sludge. Optimal growth occurred at 30-37 °C and pH 6.0-7.0. Phylogenetic analysis based on the 16S rRNA gene sequences revealed that novel isolate belonged to family Rhodobacteraceae of class Alphaproteobacteria. Strain SY72T is closely related Tabrizicola aquatica KCTC 23724T (97.8 % sequence similarity) Pseudorhodobacter aquaticus...

Heteroatom doping, pore engineering, and morphology design are efficient strategies to develop a high-performance electrode material for supercapacitors. In the periodic table of elements, nitrogen is adjacent carbon their atomic radii close each other; therefore, doping atoms can cause lattice be substantially distorted. this study, facile one-step self-template strategy synthesizing highly nitrogen-doped nanoporous wire (denoted as HNPCW) ∼100 nm diameter ∼10 μm length successfully...

Highly ordered crystalline InGaZnO (c-IGZO) TFTs have been demonstrated in subsequent processes above 550 °C compatible with memory applications. Notably, c-IGZO featured strong immunity to high temperature and hydrogen-containing unlike amorphous IGZO (a-IGZO) where agglomeration occurs. The optimized process this study show a higher on-current ($\mathrm{I}_{\mathrm{o}\mathrm{n}}$) at similar $\mathrm{V}_{\mathrm{t}\mathrm{h}}$ of −1 V, $\mathrm{I}_{\mathrm{off}}$ $1.82\times 10^{-18}$...
