The effect of ageing on YBa2Cu3O7-x obtained by the photoacoustic method
(Belgrade: International Institute for the Science of Sintering, 2003)
Thermal diffusivity and electric transport properties of fourteen years old superconducting YBa2Cu3O7-x pellets were obtained using the photoacoustic transmission technique and then compared with freshly made superconducting ...
A Contribution of Carrier Transport Processes to the Photoacoustic Effects in Doped Narrow Gap Semiconductors
(American Institute of Physics, 2003)
The contribution of free carrier transport processes to the photoacoustic effect in doped AIVBVI compounds was investigated using the photoacoustic (PA) frequency modulated transmission technique as a valuable tool in the ...
Појава церузита из рудног поља рупља (ЈИ Србија) / Cerussite occurrence from Ruplje ore field (SE Serbia)
(Геозавод, 2003)
Ispitivana je nova pojava ceruzita iz Ruplja rudno-mikroskopskim i rendgenskim metodima.
U ispitivanom uzorku utvrđeno je dominantno prisustvo ceruzita i kvarca i vrlo malo glina-liskuna, kao i ukupno oko 5% rudnih ...
Одређивање састава чврстих раствора ромбичних карбоната помоћу кристалографских параметара, део I: теорија, могућности и математички прорачуни за систем CaCO3-SrCO3 / Determination of the composition of the orthorhombic carbonate solid solutions with crystallographic parameters, Part I: Theory, possibilities and mathematical calculations for the CaCO3-SrCO3 system
(Геозавод, 2003)
Ispitivane su mogućnosti određivanja sastava čvrstih rastvora rombičnih karbonata pomoću kristalografskih parametara. Ako se kristalografski parametri menjaju linearno sa sastavom, i ako je ta zavisnost duž linije koja ...
Crystallographicaly-Mineralogical Characteristics of Gypsum from Jajinci (Near Belgrade)
(Geoinstitut, 2003)
At the two gypsum samples from Jajinci (gypsum-1 and gypsum-2) there were indiced X-ray powder diffraction patterns and qualitative-semiquantitative X-ray powder diffraction analysis were done. It was established that the ...
X-ray investigations of arsenopyrites from some ore deposits of Serbia
(Geoinstitut, 2003)
With the X-ray investigations there were examined arsenopyrites from five ore deposits of Serbia: Crveni Breg (Avala), Rudnik (Rudnik), and Sastavci, Belo Brdo and Trepča (Kopaonik). Investigations involved qualitative ...
X-ray investigations of scheelite and pyrite from Aldinac (Stara Planina Mt.)
(Geoinstitut, 2003)
At one representative sample there was indiced powder diffraction pattern and done qualitative-semiquantitative X-ray powder diffraction analysis. It was established that the investigated sample contains scheelite and ...
