The temperature dependence of the retention index for n-alkyl esters of acetic, propionic, cyclohexanecarboxylic, benzoic and phenylacetic acid on DB-1 and DB-5 capillary columns / Uticaj temperature na retencioni indeks n-alkil-estara sirćetne, propionske, cikloheksankarbonske, benzoeve i fenilsirćetne kiseline na DB-1 i DB-5 kapilarnim kolonama
(Serbian Chemical Society, Belgrade, 2006)
The temperature dependence of the retention index was studied for n-alkyl esters of acetic, propionic, cyclohexanecarboxylic, benzoic and phenylacetic acid on DB-1 and DB-5 capillary columns. The study was performed over ...
On the Al-Mg alloy sheets for automotive application: Problems and solutions
(Savez inženjera metalurgije Srbije, Beograd, 2004)
Aluminium alloys suitable for automotive application were reviewed briefly as well as the reasons for the future wider application of Al-Mg type alloys. Basic problems related to the limited consumption of Al-Mg type alloy ...
Uticaj gustine izmene za procese taloženja na nastajanje tankog površinskog sloja metala na nesrodnoj podlozi
(Engineering Society for Corrosion, Belgrade, Serbia, 2005)
Electroplating could be defined as a group of procedures in which metal surfaces (sometime nonmetals) transforms, so the surface properties are changed from base materials to the deposited metal. This goal can be achieved ...
C* integral evaluation by using EPRI procedure / Određivanje C* integrala primenom EPRI procedure
(Society for Structural Integrity and Life, Institute for Material Testing, 2002)
The EPRI procedure for evaluation of elastic-plastic fracture mechanics parameters has been described. Using an analogy of visco-plastic problem with a described procedure, the possibility of application of EPRI procedure ...
An inverse gas chromatography study of the adsorption of organics on nickel- and copper-hexacyanoferrates at zero surface coverage
(Academic Press Inc Elsevier Science, San Diego, 2002)
The surface properties of Ni and Cu hexacyanoferrates were investigated by the inverse gas chromatography method. Retentions of 10 organic compounds were measured at zero surface coverage in the temperature range 80 to 95 ...
Nanotribological properties of UHMWPE/quartz composites
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Wear of ultra-high molecular weight polyethylene (UHMWPE) and its composites is one of the main obstacles that limit the longevity of total joint replacements. Compression molded UHMWPE/quartz composites with organosiloxane ...
Conformation of N-substituted 2-phenylbutanamides / Konformacije N-supstituisanih 2-fenilbutanamida
(Univerzitet u Nišu, Niš, 2000)
Various N-substituted 2-phenylbutanamides, CH3CH2CH(Ph)CONHR, where R is ethyl, n-butyl, i-butyl, cyclohexyl and phenyl, were synthesized. They were characterized by m.p., FT-IR, 1H NMR and mass spectra. Depending on the ...
Adsorption of oxygen containing species and their effect on oxygen reduction on Pt3Co electrode
(Elsevier Science Sa, Lausanne, 2003)
A rotating Pt3Co, thermally prepared alloy disc is used to study electrochemical oxygen reduction in alkaline solutions of different pH. In all solutions two Tafel regions are found: at low current densities partial ...
Remediation of environment contaminated by lead using synthetic and natural apatites / Stabilizacija zagađenja olovom korišćenjem sintetičkih i prirodnih apatita
(Association of Chemical Engineers of Serbia, 2001)
Lead contamination is an environmental concern due to its effect on human health. One of the ways of remediating lead contamination is the in situ stabilization of this heavy metal. This can be achieved by converting ...
The morphology of cavitation damage of heat-treated medium carbon steel / Morfologija kavitacionog oštećenja srednje-ugljeničnog čelika u poboljšanom stanju
(Serbian Chemical Society, Belgrade, 2006)
In this paper the morphology of the cavitation damage to heat-treated medium carbon steel was analyzed. The experiments were conducted using a modified vibratory cavitation test set up. The erosion rates were measured by ...
