Real surface area of the aluminium electrode in sodium chloride solution
(Journal of the Serbian Chemical Society, 1999)
By combining the techniques of electrochemical slow potentiodynamic, AC impedance and atomic force microscopy (AFM), ii: was shown that the differences in the anodic dissolution rates of Al in 0.5 NaCl solutions as measured ...
Non-linear elastic behaviour of carbon fibres of different structural and mechanical characteristic
(Journal of the Serbian Chemical Society, 2007)
Five types of polyacrylonitrile, PAN, based carbon fibres, differing in modulus, breaking strain and in crystallite orientation, have been studied. Non-Hookean behaviour was investigated by computing the tangent tensile ...
The respresentative particle of copper powder and branching of copper dendrites
(Journal of the Serbian Chemical Society, 2002)
Electrochemically deposited copper powders, which are formed of particles of different size and morphology, are characterized by sonic properties like specific surface and apparent density. A procedure of the determination ...
The effect of the composition of the dispersing medium of oxide sols on the electro catalytic activity of sol-gel obtained RuO2-TiO2/Ti anodes
(Journal of the Serbian Chemical Society, 2001)
The influence of the addition of methanol, ethanol, 1-propanol and 2-propanol to the dispersing medium of a mixture of RuO2 and TiO2 sols on the electrochemically active surface area for proton exchange, as well as on the ...
Interactions of cytotoxic amino acid derivatives of tert-butylquinone with DNA and lysozyme
(Journal of the Serbian Chemical Society, 2016)
The interactions of nine amino acid derivatives of tert-butylquinone with biomacromolecules were studied. Sodium dodecyl sulphate (SDS) gel electrophoresis and mass spectrometry confirmed the absence of modifications of ...
The effect of boron on the amount and type of carbides in chromium white irons
(Journal of the Serbian Chemical Society, 2002)
The effect of boron, in the amounts of 0.26, 0.39, and 0.59 wt.%, on the volume fraction and structure of carbides in Cr white irons was examined. It was demonstrated that the addition of boron can change the microstructural ...
An improved synthesis for obtaining 2-deoxy-2-iodo-D-mannopyranose derivatives
(Journal of the Serbian Chemical Society, 1998)
The aim of this work was to synthesize 2-deoxy-2-iodo-manno sugars and 2-deoxy-2-iodo manno esters of a satisfactory purity in the highest possible yield. For this put-pose, the iodination reaction of D-glucal triacetate ...
Synthesis, crystal structure and local anti-inflammatory activity of the L-phenylalanine methyl ester derivative of dexamethasone-derived cortienic acid
(Journal of the Serbian Chemical Society, 2015)
The L-phenylalanine methyl ester derivative of dexamethasone-derived cortienic acid (DF) was synthesized and its crystal structure characterized by the X-ray diffraction method. The crystal system is orthorhombic with space ...
Thermostability and surface morphology of nano- and micro-filled NBR/CSM and CR/CSM rubber blends
(Journal of the Serbian Chemical Society, 2004)
Acrylonitrile-butadiene rubber (NBR), polychloroprene rubber (CR). chlorosulphonated polyethylene rubber (CSM) and their blends were cross-linked with sulphur, ethylene-thiourea. magnesium oxide or their combination. The ...
An estimation of the interfacial energy of the copper-copper sulphate solution interface and of the specific surface of copper powder
(Journal of the Serbian Chemical Society, 2002)
A possible way for the estimation of the interfacial energy of the copper - copper sulphate solution interface is proposed. The estimated value of (2.7 +/- 0.3) J cm(-2) and the derived equations which relate the specific ...
