In this paper, facet formation of (0001) {112¯0} {112¯2} facets during epitaxial lateral overgrowth (ELO) GaN is investigated for different Ga vapor supersaturations. The ELO was conducted via metalorganic chemical deposition on patterned GaN/sapphire templates with SiO2 masks aligned along the ?11¯00? direction GaN. Scanning electron microscopy used to characterize cross section shapes islands...

Two kinds of Bi2Se3 nanostructures, 3D rose-like hierarchitectures and monodisperse nanospheres, have been synthesized through adjusting the supersaturation of the precursor solution. Noticeable hydrogen storage capacity, amounting to 185 mA h g-1, has been found for the 3D rose-like hierarchitectures, which arises from the special micro/nano-hierarchitectures with highly crystallized flake-sub...

In this article, we analyze the kinetics of heteroepitaxial growth of GaP on Si~100! by pulsed chemical beam epitaxy on the basis of results obtained by real-time optical process monitoring. In view of the large barrier to epitaxial growth on oxygen or carbon contaminated silicon surface elements and the low stacking fault energy for GaP, residual contamination of the silicon surface contribute...

OBJECTIVE To assess the effect of dietary potassium citrate supplementation on the urinary pH, relative supersaturation of calcium oxalate and struvite (defined as the activity product/solubility product of the substance), and concentrations of magnesium, ammonium, phosphate, citrate, calcium, and oxalate in dogs. ANIMALS 12 healthy adult dogs. PROCEDURE Canned dog food was fed to dogs for ...
