Determination of the zinc and cadmium contents in low-alloyed tin
(Belgrade : Serbian Chemical Society, 1999)
The method of anodic linear sweep voltammetry (ALSV) has been used to determine the content of Zn and Cd (up to 4% w/w) in eutectic type binary alloys with Sn. The alloy samples were prepared by casting. The effect of the ...
Razvoj mikrostrukture i kristalnih faza tokom sinterovanja višefaznih materijala na bazi Zn0 i njihov uticaj na formiranje nelinearnih strujno-naponskih karakteristika
(Belgrade : University of Belgrade, Faculty of Technollogy and Metallurgy, 1993)
Rad predstavlja nastavak dosadašnjih istraživanja iz oblasti višekomponentnih materijala na bazi ZnO - Bi2O3 - MO, koji poseduju veliku nelinearnost strujno-naponske karakteristike. Nelinearno ponašanje sistema, koje se ...
Metod za određivanje efikasnosti sistema aktivne katodne zaštite plovnih objekata od korozije
(Belgrade : University of Belgrade, Faculty of Mechanical Engineering, 1995)
Korozija podvodnog dela trupa broda je jedan od izuzetno važnih problema u brodogradnji. Pored osnovnog načina zaštite dobijenog organskim premazima, postoji tendencija primene aktivne katodne zaštite pomoću spoljašnjeg ...
Strukturne i termijske karakteristike mehanohemijski tretiranih metalnih prahova
(Belgrade : University of Belgrade, Faculty of Technology and Metallurgy, 1996)
U ovom radu je ispitivano dobijanje neravnotežnin struktura u metalima mehanohemijskim tretmanom. Strukturne i termijske karakteristike prahova mehanohemijski tretiranih različito vreme mlevenja su ispitivane rendgenskom ...
Tailor made synthesis of Q-TiO2 powder by using quantum dots as building blocks
(Nanostructured Materials, 1998)
A simple synthetic procedure based on ultrasonic spray pyrolysis and usage of TiO2 quantum dots as building blocks leads to the formation of submicronic TiO2 spheres which preserved optical and catalytic properties of the ...
Photoacoustic investigation of transport in semiconductors: Theoretical and experimental study of a Ge single crystal
(The American Physical Society, 1995)
Photoacoustic (PA) heat-transmission measurements were used to study transport in a nearly intrinsic Ge single crystal. A theoretical model was developed which quantitatively describes excess carrier and thermal-wave space ...
Ultrasonic spray pyrolysis of TiO2 nanoparticles
(Nanostructured Materials, 1997)
Synthesis of ultrafine spherical TiO2 particles was achieved by using ultrasonic spray pyrolysis and nanoparticles of TiO2 (approximate to 2.5nm) as a precursor. The size distribution and morphology of TiO2 particles ...
Influence of additives on the properties of spherical nickel particles prepared by ultrasonic spray pyrolysis
(Journal of Materials Research, 1999)
Ideal spherical nonagglomerated Ni particles (mean diameter 0.62-1.12 mu m) were prepared by ultrasonic spray pyrolysis of NiCl2 aqueous solution in the presence of 0.1 mass% of Pd, Cu, or Ni in an H-2-N-2 atmosphere at ...
Synthesis of spherical beta-silicon carbide particles by ultrasonic spray pyrolysis
(Journal of the American Ceramic Society, 1996)
Fine agglomerate-free spherical beta-SiC powder was synthesized from a dispersion of colloidal silica, saccharose, and boric acid, by means of an ultrasonic spray pyrolysis method, Droplets of 2.2 mu m were formed with an ...
Nanocomposite materials prepared by using quantum dots as building blocks
(Advanced Materials and Processes, 2nd Yugoslav Conference on Advanced Materials (YUGOMAT II), Sep 15-19, 1997, Herceg Novi, Yugoslavia, 1998)
Two different synthetic procedures for preparation of composite materials using semiconductor quantum dots as building blocks have been developed. The resulting powders preserved optical and photocatalytic properties of ...
