Determination of AL2O3particle size in Cu-AL2O3 nanocomposite materials using UV spectrophotometry / Određivanje veličine čestica AL2O3 u nanokompozitnim materijalima iz sistema Cu-AL2O3 primenom UV spektrofotometrije
(Savez inženjera metalurgije Srbije, Beograd, 2008)
In order to achieve improved mechanical properties of dispersion strengthened nanocomposite, without influencing electrical and thermal conductivity it is necessary for dispersoide to be nano sized and uniformly distributed ...
Influence of the woven construction on breaking load and relaxation / Uticaj Konstrukcije Tkanine na Prekidnu Silu i Relaksaciju
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2001)
A study is made to establish the correlation between a woven construction and its mechanical strength. Dynamometric tests are carried out to determine the breaking load and breaking extension of three wooltype fabrics, as ...
The origin of high activity of Pt-Au surfaces in the formic acid oxidation
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
We have investigated the oxidation of HCOOH on Au-modified Pt (Au"Pt) and Pt-modified Au (Pt")/Au) electrodes to establish the role of the ensemble and the electronic effect in the catalysis of this reaction. The surfaces ...
Numeric analysis of tension condition of pressure vessel for the storage of beer / Numerička analiza naponskog stanja posude pod pritiskom za skladištenje piva
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2005)
Pressure vessels during the usage are exposed under very bad working conditions which make very high tension. In this work the calculation of all the elements of vertical cylindrical pressure vessel for the storage of beer ...
Numerical and analytical modeling of elastic-plastic fracture mechanics parameters
(8th Conference of the Yugoslav Materials Research Society, 2007)
Structural integrity and service reliability depend on the fracture resistance of a material. Cracks in the material are the locations of stress concentration, and elastic-plastic deformation can occur causing the development ...
Through thickness optimal design of glass-epoxy composite pressure vessel / Optimizacija strukture laminarnog kompozitnog materijala po debljini zida posude pod pritiskom
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2005)
Mechanical loading of pressure vessels mainly comes from pressure (inner and outer) under which is vessel subjected. Tension which appears changes according to the thickness of the wall. Thanks to the its specific structure, ...
Biomaterials: Joints and problems of contact interfaces / Biomaterijali - spojevi i problemi dodirnih površina
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2006)
Intensive development of modern materials enables their increasing application in biomedical engineering. To make the material under consideration applicable, it should be made biocompatible with organic material. One of ...
The Application of Recycled Wool-based Nonwoven Material for Removal of Oil from Water
(Proceedings “Futurotextiles“ International Conference, 23-24 November 2006, Lille, France, 2006)
The aim of this study was to investigate the potential utilities of recycled wool-based nonwoven material for removal of different kinds of oil from water. Sorption capacities of the material in water, oil retention, sorbent ...
