Termička stabilnost alifatskih hiperrazgranatih poliestara / Thermal stability of aliphatic hyperbranched polyesters
(Association of Chemical Engineers of Serbia, 2002)
U okviru ovog rada prikazani su rezultati dobijeni izučavanjem uticaja molarne mase (generacije), broja krajnjih grupa, kao i vrste krajnjih grupa na termičku stabilnost alifatskih hiperrazgranatih poliestara (AHP). Vrsta ...
Some Thermal and Electronic Transport Properties of YBa2Cu3O7-x Obtained by the Photoacoustic Method
(The Japan Society for Analytical Chemistry, 2001)
The possibility of simultaneous determination of some thermal and transport properties of polycrystalline YBa2Cu3O7-x, using a photoacoustic (PA) method was investigated. Both the amplitude and phase PA signals were measured ...
Anisotropy in Thermal Properties of Single Crystal α Quartz Obtained by the Photoacoustic Method
(The Japan Society for Analytical Chemistry, 2001)
Anisotropy in the thermal properties in α SiO2 single crystals SC cut mode 1 and mode 2 was investigated using the photoacosutic (PA) frequency transmission technique. The PA amplitude and phase diagrams were measured and ...
Thermoelastic and Electronic Deformation Components of Photoacoustic Signal in Two-layer System
(The Japan Society for Analytical Chemistry, 2001)
A model was derived in order to study the dependence of the photoacoustic signal on the thermal, elastic and carrier
transport properties of two-layer samples. The various systems were considered: the conductor-semiconductor, ...
Zlato u kvarcno-hematitskim mineralizacijama okoline Aldinca na Staroj planini / Gold in quartz-hematitic mineralisations of the Aldinac area at Stara planina Mountain
(Geoinstitut, 2004)
Rudnu zonu Aldinca pretežno izgrađuju gabroidne stene, predstavljene piroksenskim gabrovima i dijabazima, u koje su utisnute granitoidne stene, pretežno granodiorit-porfiriti, a u manjoj meri, kvarc-latiti i daciti. ...

(Geoinstitut, 2005)
With the X-ray powder diffraction analysis there were indiced powder diffraction patterns and determined qualitative, semiquantitative sample contents.
Sample-1 contain Mg-calcite (1) (95%), dolomite (4%) and quartz ...
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 ...
Kristalohemijska ispitivanja sfalerita iz polimetaličnog Pb - Zn rudnog ležišta Kiževak / Crystallochemicaly investigations of the sphalerites from the polymetallic Pb-Zn ore deposit Kiževak
(Geoinstitut, 2005)
With the X-ray, chemical and spectrochemical method there were investigated monomineral concentrations of the brown and yellow sphalerite varietys from the polymetallic Pb-Zn ore deposit Kiževak from the different horizons ...
Finding of hematite (specularite) at the Duškina Mala locality near Preševo, south Serbia
(Българско геологическо дружество, 2007)
At the Duškina Mala locality near Preševo (South Serbia) at the contact of the marbles with phyllite-schists was discovered hematite variety – specularite. This gray specularite has silvery metallic luster and occurs locally ...
