Synthesis of mono-dispersed mesoporous silica spheres with highly ordered hexagonal regularity using conventional alkyltrimethylammonium halide as a surfactantElectronic supplementary information (ESI) available: time courses of particle size and scattering intensity of samples obtained with TEOS and C16TMACl. See http://www.rsc.org/suppdata/jm/b3/b313712k/

Kazuhisa Yano、Yoshiaki Fukushima2004-01-01Journal of Materials Chemistry

Mono-dispersed mesoporous silica spheres with highly ordered hexagonal regularity were obtained with tetramethoxysilane (TMOS)–alkyltrimethylammonium chloride–methanol–water–sodium hydroxide. Just by changing the methanol ratio in the solvent, mono-dispersed particles were obtained with C14TMACl, C16TMACl and C18TMACl…

Photoelectrochemical Behavior of Electrodeposited CuO and Cu[sub 2]O Thin Films on Conducting Substrates

K. Nakaoka、Junichi UEYAMA、Kotaro Ogura2004-01-01Journal of The Electrochemical Society

Cuprous oxide has been prepared by the photoelectrochemical reduction of a CuO film formed on a conducting substrate by the anodic deposition from an alkaline solution of a Cu(II)-amino acid complex. Both copper oxide films thus prepared are found to be typical p-type semiconductors. The onset of the cathodic photocur…

Controlling the size of Cu2O nanocubes from 200 to 25 nm

Linfeng Gou、Catherine J. Murphy2004-01-01Journal of Materials Chemistry

Highly uniform Cu2O nanocubes can be prepared by using a simple solution approach. Copper(II) salts in water are reduced with ascorbic acid in air in the presence of polyethylene glycol (PEG) and sodium hydroxide. The average edge length of the cubes can be controlled from 25 to 200 nm by changing the order of additio…

Multiband Tight-Binding Model of Local Magnetism in Ga1-xMnxAs

Jian‐Ming Tang、Michael E. Flatté2004-01-01Physical Review Letters

We present the spin and orbitally resolved local density of states (LDOS) for a single Mn impurity and for two nearby Mn impurities in GaAs. The GaAs host is described by a sp(3) tight-binding Hamiltonian, and the Mn impurity is described by a local p-d hybridization and on-site potential. Local spin-polarized resonan…
