Selective area epitaxial growth of Hg1-xCdxTe by isothermal vapor-phase epitaxy
(IEEE Computer Society, 2000)
We used mechanical shadow masks, which are made by silicon micromachining, to obtain selective area epitaxial (SAE) growth of (Hg,Cd)Te on CdTe substrates. The layers were grown by isothermal vapor phase epitaxy (ISOVPE) ...
The crystallization and optical properties of LiNbO3 single crystals / Kristalizacija i optičke osobine monokristala LiNbO3
(Belgrade : Serbian Chemical Society, 2000)
LiNbO3 single crystals were grown by the Czochralski technique in an air
atmosphere. The critical crystal diameter Dc = 1.5 cm and the critical rate of rotation wc
= 35 rpm were calculated from the dynamic of fluids ...
Peracids oxidation of cholesta-5,8-dien-3β-yl acetate / Oksidacija holesta-5,8-dien-3β-il acetata sa perkiselinama
(Serbian Chemical Society, 2000)
Expoxidation of cholesta-5,8-dien-3β-yl acetate (1) with peracids takes place preferentially at the more highly substituted Δ8-olefinic double bond to give: (a) with monoperphthalic acid, 8α,9α-epoxycholest-5-en-3β-yl ...
The Effect of Some parameters of Electrolysis on Apparent Density of Electrolytic Copper Powder in Galvanostatic Deposition
(Switzerland : Trans Tech Publications Ltd, 2000)
The investigation on some properties of electrochemically deposited copper powders from copper sulphate - sulfuric acid has been performed. Relations between conditions of electrolysis of powder storage, apparent density ...
Drying of suspension and pastes in fluidized bed of inert particles / Sušenje suspenzija i pasta u fluidizovanom sloju inertnog materijala
(Serbian Chemical Society, 2000)
A fluid bed dryer with inert particles was used for the drying of suspensions and pastes. The effects of the operating conditions on the dryer throughput and on the product quality were investigated. Experiments were ...
The Preferred Orientation of Bright Copper Deposits
(Switzerland : Trans Tech Publications Ltd, 2000)
The preferred orientations of copper deposits obtained from acid sulfate solutions were examined. Mat deposits obtained in the absence of the additives and in the presence of disodium 2-naphtol-3,6-disulfonic acid possessed ...
