Evolution of the structural and microstructural characteristics of SrSn1 − xTixO3 thin films under the influence of the composition, the substrate and the deposition method
SrSn1 − xTixO3 thin films were grown on R-sapphire and (100) LaAlO3 single crystal substrates by two different routes: chemical solution deposition (CSD) and pulsed laser deposition (PLD). Structural and microstructural ...
Evolution of the structural and microstructural characteristics of SrSn1 - xTixO3 thin films under the influence of the composition, the substrate and the deposition method
(Elsevier B.V., 2017-03-15)
SrSn1 (-) xTixO3 thin films were grown on R-sapphire and (100) LaAlO3 single crystal substrates by two different routes: chemical solution deposition (CSD) and pulsed laser deposition (PLD). Structural and microstructural ...
Plasma-polymerized acetylene nanofilms modified by nitrogen ion implantation
Thin films were prepared by plasma enhanced chemical vapour deposition (PECVD) from a mixture of acetylene and argon, and post deposition-treated by plasma immersion ion implantation (PIII). The effect of PIII on the ...
Direct block-support simulation of grades in multi-element deposits: application to recoverable mineral resource estimation at Sungun porphyry copper-molybdenum deposit
(Southern African institute mining metallurgy, 2017)
Recoverable mineral resources assessment has become a standard geostatistical application in the mining industry, with various geostatistical techniques currently available. This investigation aimed to improve the prediction ...
Geological and geophysical data integration for delimitation of mineralized areas in a supergene manganese deposits
(Inst Geophysics Unam, 2014-04-01)
Geophysical methods are widely used in mineral exploration. This paper discusses the results of geological and geophysical studies in supergene manganese deposits of southern Brazil. Mineralized zones as described in ...
Low-temperature, self-nucleated growth of indium-tin oxide nanostructures by pulsed laser deposition on amorphous substrates
(Elsevier B.V., 2006-12-01)
Indium-tin oxide nanostructures were deposited by excimer laser ablation in a nitrogen atmosphere using catalyst-free oxidized silicon substrates at 500 degrees C. Up to 1 mbar, nanowires grew by the vapor-liquid-solid ...
