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…

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…

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…

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…

In its most common configuration, a solid oxide fuel cell (SOFC) uses an oxygen‐ion conducting ceramic electrolyte membrane, perovskite cathode, and nickel cermet anode electrode. Cells operate in the 600–1000°C temperature range and utilize metallic or ceramic current collectors for cell‐to‐cell interconnection. Rece…

Crystalline solids undergo large changes in their structure and properties as they transform between different polymorphs in response to the pressure and the temperature. It now appears that analogous density- or entropy-driven phase transitions also occur within the liquid state: these represent a new type of general…
