The formation of oxide nanoparticles on the surface of natural clinoptilolite
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Nanoparticles of NiO, ZnO and Cu(2)O crystallize when the Ni-, Zn- and Cu-exchanged natural clinoptilolite, respectively, are dehydrated by heating in air at 550 degrees C. The dehydration of Mn-exchanged clinoptilolite ...
The effect of accelerated aging on the mechanical properties of PMMA denture base materials modified with itaconates / Uticaj ubrzanog starenja na mehanička svojstva poli(metil-metakrilatnih) materijala za bazu zubnih proteza modifikovanih itakonatima
(Association of Chemical Engineers of Serbia, 2011)
This study evaluated the effect of accelerated aging on tensile strength, elongation at break, hardness and Charpy impact strength in commercial PMMA denture base material modified with di-methyl itaconate (DMI) and ...
Influence of picosecond laser pulses on the microstructure of austenitic materials
(Springer, New York, 2011)
We investigate samples of austenitic materials - stainless steel and iron-based superalloy - which are widely used at high temperatures and pressures. The samples were exposed to Nd(3+):YAG laser pulses with a wavelength ...
The analysis of forming PVB-SiO2 nanocomposite fibers by the electrospinning process / Analiza formiranja PVB-SiO2 nanokompozitnih vlakana pomoću elektrospining procesa
(Vojnotehnički institut, Beograd, 2011)
The poly (vinyl butyral)-silica (PVB-SiO2) nanofibers were obtained by the electrospinning process. The experiments were carried out with PVB solution in concentration of 10 wt.% where ethanol was used as the solvent. The ...
Structural and mechanical properties of different hard welded coatings for impact plate for ventilation mill
(SUDURA Publishing House, 2011)
Influence of Microwave Heating on the Polymerization Kinetics and Application Properties of the PMMA Dental Materials
(Wiley, Hoboken, 2011)
The effects of heating mode (conventional isothermal heating (CIH) and microwave isothermal heating (MWIH) on the kinetics of polymerization and the properties important for the application (residual monomer, hardness, and ...
Application of electrochemical methods for the investigation of intergranular corrosion of welded joint of austenitic stainless steel 19cr-9ni
(Savez hemijskih inženjera, Beograd, 2011)
The sensitization degree of austenitic stainless steel welded joints was investigated by electrochemical methods of the double loop electrochemical potentiokinetic reactivation (DL EPR) in H(2)SO(4) + KSCN solution, and ...
The enzyme separation plant modelling, design and optimization
(International Journal of Mathematical Models and Methods in Applied Sciences, 2011)
A new approach for plant model building was illustrated. The use of flowsheeting in design, however, differs from its use in operations and this should be reflected in the development of the simulation procedure. In design, ...
Distribution of loads of cycloid speed reducer
(University of Timisoara, Transactions on Mechanics, 2011)
Cycloidal speed reducer belongs to the generation of modern planetary gears. It main features are:
high transmission ratio, compact design, long and reliable working life, high efficiency, possibility of accepting
big ...
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. ...
