The roles of the ruthenium concentration profile, the stabilizing component and the substrate on the stability of oxide coatings
(Elsevier, 1992)
Electrocatalytic oxide coatings with variable concentration profiles of RuO2 as the active component were obtained through a combination of separately applied layers of RuO2, TiO2, IrO2, RuO2 + TiO2 and RuO2 + IrO2 on ...
Electrosorption of hydrogen and sulfuric acid anions on single crystal platinum stepped surfaces. Part II. The [110] zone
(Elsevier, 1991)
Hydrogen and bisulphate adsorption at platinum single crystal surfaces from the [ITO] zone is
strongly dependent on the crystallographic orientation of the electrode surface, which is similar to that
found earlier for ...
X-ray crystal structure of 10β-hydroxy-4β,5β-epoxyestr-1-en3,17-dione and antitumor activity of its congeners
(MDPI, 1999)
Based on the biological properties of epoxyquinols from natural sources, the title compound was synthesised as a potential antitumor agent. Its molecular structure was partially confirmed by NMR studies. The detailed ...
Ispitivanje dinamike protonskih vrsti kod fosformolibdenove kiseline metodom infracrvene i mikro-ramanske spektroskopije
(Belgrade : Serbian Chemical Society, 1994)
U ovom radu izloženi su najnoviji rezultati sistematskog ispitivanja heteropolikiselina kao protonskih provodnika, posebno 29-hidrata fosformolibdenove koseline (MoPA-29).
Metodama infracrvene i mikro-Ramanske spektroskopije, ...
Surface diffusion of clusters and thin film growth
(Elsevier, 1995)
An analogy between the behavior of real gases and the behavior of clusters deposited on a surface has been established. A relation similar to the Van der Waals equation was used, with the variables corresponding to the ...
Test of the validity of some kerogen models based on oxidative degradation
(Elsevier, 1990)
Molecular models of considerable complexity have been proposed recently for type I, II and III kerogens. Here, we describe the amount and type of carboxylic acids that one would expect to result from their multistep alkaline ...
Oxygen reduction on Au(111) and vicinal Au(332) faces: A rotating disc and disc-ring study
(Elsevier, 1994)
The kinetics of oxygen reduction on the Au(111) surface in acidic solution has been re-examined by means of a rotating disc electrode technique. Its vicinal Au(332) = Au[6(111) × (111)] surface has been chosen to examine ...
Real surface area of the aluminium electrode in sodium chloride solution / Stvarna površina eletrode od aluminijuma u rastvoru natrijum-hlorida
(Belgrade : Serbian Chemical Society, 1999)
By combining the techniques of electrochemical slow potentiodynamic, AC impedance and atomic force microscopy (AFM), it was shown that the differences in the anodic dissolution rates of Al in 0.5 NaCl solutions as measured ...
Effect of substituents on the 13 C chemical shifts of the azomethine carbon atom of N-(phenyl substituted) pyridine-4-aldimines
(Elsevier, 1999)
13 C chemical shifts of the azomethine carbon atom for N-(substituted phenyl)pyridine-4-aldimines, 4-Py-CH=N-C 6 H 4 -X, X having a wide range of substituent effects, have been determined in CDCl 3 solution. Exceptionally ...
Standard potential values of "cyanide-sensitive" silver iodide and silver sulphide ion-selective electrodes
(Analytica Chimica Acta, 1990)
It is shown that the equation for the potentials of semiconductive sulphide membranes given by Sato 25 years ago is valid also for the calculation of E0 values of "cyanide-sensitive" ion-selective electrodes. The only ...
