A dual interface SiOx/C composite is prepared through a novel, facial, one-step route by redox reaction of organic carbon with silica precursor, using tetraethyl orthosilicate (TEOS) and sucrose as raw material, in which sucrose acts as both a reductant and coated carbon. HRTEM indicates that the composite has a dual interface structure with carbon...

We report an optically gated transistor composed of CdSe nanocrystals (NCs), sensitized with the dye Zinc beta-tetraaminophthalocyanine for operation in the first telecom window. This device shows a high ON/OFF ratio of six orders of magnitude in the red spectral region and an unprecedented 4.5 orders of magnitude at 847 nm. By transient absorption...
Three different morphologies of FeTiOx materials (microcubes, etched-microcubes and microspheres) were prepared by a facile method using acid leachate of ilmenite as the precursor. The three FeTiOx materials exhibited different adsorption performance for Congo red (CR). Among them, the FeTiOx microspheres showed the highest adsorption capacity (723...

Cathode materials that have better thermal stability, larger specific capacity and higher conductivity can efficiently improve the electrochemical performance of the batteries. In this work, we synthesized tungsten disulfide (WS2) nanosheet and investigated its applicability as cathode material for thermal battery. The WS2 is thermally stable up to...
In this work, a novel method was utilized for the gas-liquid reactive crystallization of Li2CO3 in a LiCl-NH3 center dot H2O-CO2 system and the time-dependences of crystallization parameters were investigated carefully. The results indicated that [NH4+] had great influence on the Li2CO3 precipitation process, and that it could inhibit the recarbona...

W-Cu composites with homogenous Cu-network structure were fabricated by spark plasma sintering using core-shell powders. The core-shell powders were obtained by intermittently electroplating method which can deposit shell composed of nano-copper on the core of micron tungsten particles. These nano-copper shells provide a large amount of grain bound...
