Rechargeable lithium ion batteries are important energy storage devices; however, the specific energy of existing lithium ion batteries is still insufficient for many applications due to the limited specific charge capacity of the electrode materials. The recent development of sulfur/mesoporous carbon nanocomposite cathodes represents a particularly exciting advance, but in full battery cells, ...

The fabrication of SiC ceramic materials with an ordered nanostructure through the direct pyrolysis of a self-assembled inorganic-organic block copolymer has generally been unsuccessful even though the versatile processibility has been demonstrated with organic-organic block copolymers. Here we report the synthesis of a novel polycarbosilane-block-poly(methyl methacrylate) diblock copolymer thr...

Fe and Ni doped mesoporous Co3O4 (mCo3O4) catalysts were prepared and investigated for electrochemical oxygen evolution. The incorporation of Fe into mCo3O4 (Fe-mCo3O4) results in unusual synergistic effects via destruction of the bulk mesoporous structure and formation of slit-like pores. The Fe-mCo3O4 composite displayed a significantly enhanced catalytic activity for oxygen evolution.

ZnO thin films were successfully deposited via spray pyrolysis technique over various substrates, including glass, silicon, and mesoporous silicon (PSi). The effect of substrate type on the surface morphological, structural, electrical properties film was investigated. Scanning Electron Microscopy confirms morphology meso-PSi displays morphologies ZnO. (ZnO/PSi) heterojunction shows a porous la...

The design, fabrication and characterization of an inorganic catalyst based direct glucose fuel cell using mesoporous silica coating as a functional membrane is reported. The desired use of mesoporous silica based direct glucose fuel cell is for a blood vessel implantable device. Blood vessel implantable direct glucose fuel cells have access to higher continuous glucose concentrations. However,...

In this work a two-step procedure is reported for the formation of ZnO/porous silicon (PS) composites in which ZnO is embedded in the pores of sponge like mesoporous silicon. The procedure consists of an isothermal annealing of the PS layer in Zn vapors using a close space configuration and a subsequent oxidation of the Zn infiltrated in the pores. The oxidation agent and the annealing duration...

UNLABELLED Mesoporous silicon and porous silicon/Ni nanocomposites have been investigated in this work employing light-dark surface photovoltage (SPV) transients to monitor the response of surface charge dynamics to illumination changes. The samples were prepared by anodization of a highly n-doped silicon wafer and a subsequent electrodepositing of Ni into the pores. The resulting pores were or...

A successful prescription is presented for acetylcholinesterase physically adsorbed on to a mesoporous silicon surface, with a promising hydrolytic response towards acetylthiocholine iodide. The catalytic behaviour of the immobilized enzyme was assessed by spectrophotometric bioassay using neostigmine methyl sulfate as a standard acetycholinesterase inhibitor. The surface modification was studi...
