Chemical composition of the essential oil of micromeria albanica (Griseb. ex K. Maly) Silic
(Taylor & Francis, 1999)
The composition of the essential oil of the Balkan peninsula endemic plant Micromeria albanica (Griseb. ex. K. Maly) Silic was analyzed for the first time by GC and GC/MS. The oil, which was present in 0.9% (v/w) yield, ...
Synthesis and evaluation of several cathechol bioisosteres as potential dopamine receptor ligands
(Elsevier, 1991)
Derivatives of benzimidazole (I), benzimidazolone (II), benzimidazolethione (III), 2,3-dihydroxyquinoxaline (IV) and the noncyclic acetamide (V) and t rifluoroacetamide (VI) of the corresponding 1,2-pheny-lenediamiane were ...
Selenium content and distribution in rat tissues irradiated with gamma rays
(Heidelberg : Springer, 1992)
The effects of supplementation with selenous yeast and ionizing radiation on selenium (Se) content and distribution were evaluated in rat tissues (liver, kidney, spleen, heart, muscle, blood, front brain, hind brain, ...
Oxygen reduction on iron-V. Processes in boric acid-borate buffer solutions in the 7.4-9.8 pH range
(Elsevier, 1991)
O2 and H2O2 reduction was studied on Puratronic iron (99.995%) in borate buffer solutions of various pH ranging from 7.4 to 9.8. In solutions of pH < 9.3 the E-j curves are of quite irregular shapes and the limiting current ...
Nickel film orientation change by nitrogen ion bombardment during deposition
(Elsevier, 1997)
The influence of nitrogen ion bombardment during e-beam triode ion plating of nickel on the microstructure and film orientation has been investigated. The deposition variables explored were the ion current density and ...
Properties of glassy carbon modified by immersing in metal cation solutions
(Vacuum, 1990)
Glassy carbon (GC) surfaces: 'as produced' in the carbonization process, abrased and oxidized were studied using AES, XPS and cyclic voltammetry. Evidence for the existence of an outer sheath formed during carbonization, ...
Scanning tunnelling microscopy of the nucleation and growth of sputter-deposited Cr on graphite
(Elsevier, 1995)
In this paper, we present a study of the nucleation and growth stages of sputter-deposited Cr thin films on highly oriented pyrolytic graphite (HOPG) substrates using scanning tunnelling microscopy (STM) in air. Freshly ...
RuO2–TiO2 coated titanium anodes obtained by the sol–gel procedure and their electrochemical behaviour in the chlorine evolution reaction
(Elsevier, 1999)
TiO2 and RuO2 sols were obtained from RuCl3 and TiCl3 aqueous solutions by condensation and forced hydrolysis
at elevated temperature. The Ti supported coatings were obtained by the sol–gel method using a sol mixture in ...
Structural effects in electrocatalysis. Oxidation of D-glucose on single crystal platinum electrodes in alkaline solution
(Elsevier, 1991)
Electrochemical oxidation of D-glucose has been studied in 0.1 M NaOH on single crystal platinum electrodes with thirteen different orientations. The reaction rate depends strongly on the crystallographic orientation of ...
Demineralization of an oil shale by Bacillus circulans (“siliceous bacteria”)
(Elsevier, 1990)
Experiments are presented aimed at removing the silicates from an oil shale by a chemoorganoheterotrophic bacterium, Bacillus circulans. This process was expected to substitute the drastic HF-treatment in the kerogen ...
