Composition and antibacterial activity of achillea chrysocoma essential oil
(Taylor & Francis, 2000)
Essential oil of Achillea chrysocoma Friv. was investigated for composition and antibacterial activity. Twenty-eight identified compounds constituted 91.5% of the oil. The main compounds of the oil were borneol (10.1%), ...
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 ...
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 ...
Volatile constituents of Achillea serbica Nym.
(John Wiley and Sons Ltd, 2000)
The volatile constituents of Achillea serbica Nym. (Asteraceae), an endemic plant of the Balkan Peninsula, has been analysed using GC and CC-MS. Fifteen identified components constituted 95.7% of the oil. The major fractions ...

The influence of the aging time of RuO2 and TiO2 sols on the electrochemical properties and behavior for the chlorine evolution reaction of activated titanium anodes obtained by the sol-gel procedure
(Elsevier, 2000)
The influence of the aging time of RuO2 and TiO2 sols used for the preparation of (40% RuO2+60% TiO2)/Ti anodes by the sol-gel procedure on the electrochemical properties and behavior for the chlorine evolution reaction ...
An efficient semisynthesis of 7-deoxypaclitaxel from taxine
(Journal of the Chemical Society, Perkin Transactions 1, 2000)
A semisynthesis of 7-deoxypaclitaxel 4 is described, starting from taxine 6 - the most abundant naturally occurring taxane diterpene fraction. A key step in this transformation is a tandem reaction: stereoselective osmylation ...
The Schottky barrier contribution to photoacoustic effect in Au-Si system
(IEEE Computer Society, 2000)
The photoacoustic effect in metal-semiconductor system, i.e., the influence of Schottky barrier on the thermal and electronic transport processes in semiconductor was investigated. The amplitude and phase spectra were ...
Investigation of ion-beam modified silicon by photoacoustic method
(IEEE Computer Society, 2000)
Thermal, elastic and electronic transport properties of ion-modified silicon samples were investigated by a photoacoustic frequency transmission technique. The experimental photoacoustic data vs the modulating frequency ...
Alkylation of carbonyl compounds in the TiCl4-promoted reaction of trimethylsilyl enol ethers with ethylene oxide
(Oxford : Pergamon-Elsevier Science Ltd, 2000)
Titanium tetrachloride promoted reaction of trimethylsilyl enol ethers with ethylene oxide affords homoaldol type products in moderate/good yields. The reaction is believed to proceed via the titanium enolates. (C) 2000 ...
