α‒Fe2O3/MoS2 nanocomposites were synthesized via hydrothermal method and characterized in terms of crystal structure, particle size and morphology, elemental purity and optical properties. Results confirmed the formation of α‒Fe2O3/MoS2 nanocomposites containing hematite nanoparticles with average diameter of 40 nm and MoS2 nanosheets with hexagonal crystal structure and sheet thickness o...

the crystal structure of the title schiff base complex is obtained by single-crystal x-ray diffraction data.the solid state structure determination reveals that the coordination geometry around the copper(ii) center istetrahedrally distorted square-planar. the crystal packing shows one dimensional infinite chains which arisesfrom the intermolecular interaction and stabilize the crystal packing.

Nanocrystalline ZnO particles were prepared by a novel sonochemical route from zinc acetate and sodium hydroxide without any requirement of calcination steps at high temperature and without surfactants. Variations in several parameters and their effects on the structural (crystal size and morphology) properties of nanoparticles were investigated. Characterizations were carried out by X-Ray ...

1 Abstract Exact and general results on the electronic states in one dimensional crystals bounded at τ and τ + L-where L = Na, N is a positive integer and a is the potential period-are presented. Corresponding to each energy band of the Bloch wave, there are N − 1 states in the finite crystal and their energies are dependent on the crystal length L but not on the crystal boundary τ and map the ...

As the size of quartz resonator continues to shrink, beveling of the plano-plano quartz crystal is needed to reduce mounting loss and to sustain energy trapping so to have low motional resistance for oscillation. The beveling process though is time consuming and difficult to control for small size and low frequency quartz crystals. In recent years, studies on stepped electrode (a.k.a bi-mesa el...

The effect of crystal size on VHP sugar colour was evaluated on a factory scale over the 1988/89 season at Sezela. Generally, smaller crystals produced lower sugar colour but the difference wasnot significant (at the 5% level) in the size range tested. Smallercrystals producedloweraffinated sugarcolourand the difference was significant at the 5% level. The mass of sugar in a full rail truck was...
