Сидеритични прослојци у понту околине Неготина
(Geoinstitut, 1993)
Prilikom izdvajanja formacija u neogenu Srbije, duž Save i Dunava (Krstić i dr., 1992) postavilo se pitanje proslojaka sa karbonatom. U vezi sa tim konsultovani su A. Antonović, D.B. Milovanović i druge kolege. Prihvaćena ...
A photoacoustic investigation of transport properties and thermal diffusivity of InSb single crystals
(Elsevier, 1996)
Thermal and electronic transport properties of low-doped single crystal InSb were determined for the first time and analyzed using a photoacoustic frequency heat transmission technique. The thermal diffusivity, excess ...
Transport properties of carriers in GaAs obtained using the photoacoustic method with the transmission detection configuration
(IOP Publishing Ltd, 1996)
Electron transport properties of single-crystal GaAs were determined using the photoacoustic method with the transmission detection configuration. The excess-carrier lifetime, the front and the rear recombination velocity, ...
Međusobna zavisnost uslova sinterovanja, mikrostrukture i magnetnih svojstava sinterovanih SmCo5 magneta
(Savez inženjera metalurgije Srbije, 1999)
Razmatran je uticaj procesnih promenljivih na mikrostrukturu i magnetna svojstva sinterovanih SmCo5 magneta. Neposredan uticaj mikrostrukture na magnetna svojstva sinterovanih uzoraka omogućava sagledavanje procesa dobijanja ...
Thermoelastic and electronic strain contributions to the frequency transmission photoacousticeffect in semiconductors
(The American Physical Society, 1997)
The photoacoustic effect is investigated as a function of the modulation frequency in a transmission detection configuration for semiconductor samples. The theoretical model for this configuration is given for the thermal ...
Thermal and Electronic Transport Properties of Single Crystal PtSb 2 Obtained by the Photoacoustic Method
(Institute of Pure and Applied Physics, 1997)
Single crystal PtSb2 ingots were synthesized using the Bridgman technique. Electronic transport properties and thermal diffusivity of PtSb2 sample were determined using the photoacoustic (PA) method with transmission ...
Liquefaction behaviour of Kolubara soft brown coal
(Elsevier B.V., 1994)
The behaviour of Kolubara soft brown coal during direct liquefaction by catalytic hydrogenation was studied and was compared with the Banovići brown coal investigated previously. A sample of washed and dried coal was ground ...
Direct hydroliquefaction of a low rank soft brown coal
(Elsevier B.V., 1998)
The behaviour of the soft brown coal from the Kostolac Mine (Serbia, Yugoslavia) was investigated during hydroliquefaction carried out in a batch reactor by direct catalytic hydrogenation of the pulverized coal (- 160 μm) ...
