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, ...
Oxidative processes during heat treatment in intermetallic SmCo5 powder / Oksidacioni procesi pri zagrevanju praha intermetalnog jedinjenja SmCo5
(Belgrade : Serbian Chemical Society / Beograd : Srpsko hemijsko društvo, 1996)
Understanding of the thermal stability of intermetallic SmCo5 powder is essential for designing the working atmosphere in all phases of the technological procedure in the production of sintered SmCo5 magnets to obtain ...
Evaluation of the effects of native minerals on the organic matter of Aleksinac oil shale based on the composition of free and bound bitumens
(Organic Geochemistry, 1992)
In order to evaluate the adsorption and catalytic effects of indigenous carbonates and silicates on the organic matter of Aleksinac oil shale, the free and the bound bitumens were isolated and analyzed by organic geochemical ...
Mechanism and kinetics of the electrosorption of sulphate anions on the (111) face of silver / Mehanizam i kinetika elektrosorpcije sulfatnih anjona na (111) pljosni srebra
(Belgrade : Serbian Chemical Society, 1999)
The processes of adsorption of sulphate anions onto the (111) face of silver have been investigated by analysis of the cyclic voltammetry and potcntiostatic pulse results. It was shown, by fitting the experimentally recorded ...
Metal-organic matter interactions in the formation of an oil shale deposit
(Elsevier, 1990)
An attempt was made to distinguish metal-organic matter interactions in two types of sulfate-reducing environments, mild (MR) and strong sulfate-reducing (SR), in the Aleksinac oil shale deposit (Oligocene-Miocene). Samples ...
Electrochemical Deposition and Dissolution of Alloys and Metal Composites—Fundamental Aspects
(Springer Science and Business Media LLC, 1995)
It is general experience in materials science that alloys can exhibit qualities that are unobtainable with the parent metals. This is true of electroplated deposits as well. Thus, such properties as hardness, tensile ...
Structural effects in electrocatalysis: oxygen reduction on platinum low index single-crystal surfaces in perchloric acid solutions
(Elsevier, 1994)
Oxygen reduction has been studied in 0.1 M HClO4 on the platinum low index surfaces, employing a hanging meniscus rotating-disk technique. A special cleaning procedure has been developed to remove impurities from the surface ...
Substituent efects on the carbon-13 chemical shifts in α-phenylpyridylacrylic acids
(Elsevier Science Publishers B.V., 1992)
The 13C N.M.R. spectra of some substituted α-phenylpyridylacrylic acids, α-phenyl, α-(3-pyrydyl) and α-(3-pyrydyl-N-oxide) cinnamic acids were determined in deuterated dimethyl sulfoxide (d6-DMSO). It has been shown that ...
The electrocatalytic properties of the oxides of noble metals in the electro-oxidation of some organic molecules
(Elsevier, 1997)
The electro-oxidation of organic compounds on gold and silver electrodes can occur either in a potential range more negative than that where the metal oxides are formed or within the more positive range where the surface ...
The initiation of dendritic growth of electrodeposited copper on a rotating disc electrode with changing copper concentration and diffusion layer thickness
(Elsevier, 1992)
It is shown that the critical overpotential of dendritic growth initiation increases with increasing copper concentration under identical hydrodynamic conditions, as well as with increasing rotation speed to the rde (rotating ...
