The analysis of stability of the electrospinning process of forming PVB-SiO2 nanocomposite fibers
(Belgrade : Materials Research Society of Serbia, 2011)
The PVB-SiO2 composite nanofibers were obtained by the electrospinning process. The experiments were carried out with PVB solution in concentration of 10 wt% where as the solvent was used ethanol. The silica nanoparticles ...
Comparison of the properties of the household fabric softeners from domestic production with the imported ones
(Skopje : Society of chemists and technologists of Macedonia, 2011)
Household fabric softeners were introduced to the consumers in early 1950s in order to maintain the handle and freshness even after several washings. The three methods of applying fabric softeners to textile, which are the ...
Solid state synthesis of extra phase-pure Li4Ti5O12 spinel
(Belgrade : International Institute for the Science of Sintering, 2011)
Extra phase-pure Li4Ti5O12 spinel with particle sizes less than 500 nm was synthesized by solid state reaction of mechanochemicaly activated mixture of nano anatase and Li2CO3 for a very short annealing time, 4 h at 800°C. ...
DETERMINATION OF THERMAL CONDUCTIVITY OF THE INSULATION MATERIALS USING NUMERICAL CALCULATION OF THE PRESSURE INCREASE
(Materials Research Society of Serbia, Crna Gora, 2011)
In the paper is presented the possibility of determination thermal conductivity for the
insulation materials, which are used in the tanks for liquid carbon dioxide, in situ. For this
purpose, was developed the mathematical ...

Mreža bežičnih senzora za merenje vibracija na građevinskim objektima
(Društvo Metrologa Srbije, 2011)
Nedestruktivno praćenje stanja građevinskih objekata se bazira na merenju vibracija objekata pri dinamičkim ispitivanjima ili u toku njihove eksploatacije. U ovu svrhu se sve više koriste mreže bežičnih senzora (WSN) koje ...
Analysis of floating-head heat exchanger bolts failure
(Timisoara, Romania, 2011)
As-received floating-head heat exchanger bolts were broken (BB) and deposite-coated. The aim was to estimate
a cause of their failure. The new bolts of the same material were used as a reference material (reference bolt ...
Investigation of intergranular corrosion welded joint of austenitic stainless steel by electrochemical methods
(SUDURA publising house, Rumunija, 2011)
Sensitization degree of the austenitic stainless steel welded joints was investigated by
electrochemical methods: the double loop electrochemical potentiokinetic reactivation (DL EPR) in H2SO4 +
KSCN solution and by of ...
