Rheological behaviour of thermoplastic poly(ester-siloxane)s / Reološko ponašanje termoplastičnih poli(estar-siloksana)
(Association of Chemical Engineers of Serbia, 2010)
Two series of thermoplastic elastomers (TPES), based on poly(dimethylsiloxane) (PDMS) as the soft segment and poly(butylene terephthalate) (PBT) as the hard segment, were analyzed by dynamic mechanical spectroscopy. In the ...
Supercritical CO2 extract and essential oil of bay (Laurus nobilis L.): Chemical composition and antibacterial activity / Natkritični ekstrakt i etarsko ulje lovora (Laurus nobilis L.) - hemijski sastav i antibakterijska aktivnost
(Srpsko hemijsko društvo, Beograd, 2010)
The present study deals with the supercritical carbon dioxide (SC-CO2) extraction and hydrodistillation (HD) of dried bay leaves (Laurus nobilis L.). The chemical composition and antibacterial activity of the SC-CO2 extract ...
Selection of strains from Lactobacillus sp. for lactic acid fermentation of thin stillage
(Технолошко-металуршки факултет, Београд, 2010)
Bioethanol produced by fermentation of biomass, such as sugar, starch, or lignocellulosic materials, is one of the most important renewable energy resources today. Beside the bioethanol, considerable amounts of by-products ...
Age hardening potential of an Al-4.6 wt.% Mg alloy with Cu addition
(Belgrade : Institute of Technical Sciences of SASA, 2010)
The ageing behavior of an Al-4.6Mg-0.54Cu (in wt.%) alloy was studied after: (i) solution
treatment for 1h at 530°C, and (ii) annealing at 280°C for 3h. Both groups of the heat treated
specimens underwent further ...
Gamma Radiation Absorption Characteristics of Concrete with Components of Different Type Materials
(Acta Physica Polonica A, 2010)
Nuclear facilities as nuclear power stations, nuclear research reactors, particle accelerators and linear accelerator in medical institution using concrete in building construction. The different type materials of the ...
Influence of notch radius and microstructure on the fracture behavior of Al-Zn-Mg-Cu alloys of different purity
(Elsevier, 2010)
The influence of notch radius on the fracture behavior of two high-strength Al-Zn-Mg-Cu alloys with different Fe content in the T73 condition was investigated. The fracture toughness tests were performed on non-fatigue-precracked ...
Multifunkcionalna svojstva pamučne tkanine modifikovane koronom i koloidnim nanočesticama TiO2
(Srpsko hemijsko društvo, 2010)
Mechanical and magnetic properties of composite materials with polymer matrix
(Technical Faculty, Bor, 2010)
Many of modern technologies require materials with unusual combinations of properties that cannot be met by the conventional metal alloys, ceramics, and polymeric materials. Material property combinations and ranges have ...
Synthesis and characterization of semi-interpenetrating networks of chitosan and poly(N-vinyl-2-pyrrolidone) / Sinteza i karakterizacija semi-interpenetrirajućih mreža hitozana i poli(N-vinil-2-pirolidona)
(Association of Chemical Engineers of Serbia, 2010)
Semi-interpenetrating networks (semi-IPNs) based on chitosan and poly(N-vinyl-2-pyrrolidone) were prepared in order to achieve better mechanical properties. The samples were characterized by FTIR, SEM, DMA analysis and the ...
