The effect of preparation of aluminum surface on the structure of final coating of nickel / Uticaj pripreme površine aluminijuma na strukturu završne prevlake nikla
(Belgrade, Serbia : Engineering Society for Corrosion, 2003)
In this work structure characteristics of the final coating of nickel were studied. Nickel was deposited onto chemically prepared aluminum, chemically and electrochemically. Structural characteristics of metallic coatings ...
Ballistic magnetoresistance versus magnetostriction effects in electrodeposited nanocontacts at room temperature
(Institute of Electrical and Electronics Engineers, Inc., 2003)
The authors present experiments and discuss recent results on ballistic magnetotesistance in nanometer size (on the order of 1 to 10 nm) nanocontacts grown by electrodeposition in
thin wires and in thin films of a few ...
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 ...
Oxidative Fragmentations of the 5-alpha and 5-beta-Hydroxy-B-norcholestan-3-beta-yl Acetates
(Wiley, 2003)
Oxidations of 5α‐hydroxy‐B‐norcholestan‐3β‐yl acetate (8) with Pb(OAc)4 under thermal or photolytic conditions or in the presence of iodine afforded only complex mixtures of compounds. However, the HgO/I2 version of the ...
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 ...
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 ...
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 ...
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 ...
Partial purification and characterization of midgut leucyl aminopeptidase of Morimus funereus (Coleoptera : Cerambycidae) larvae
(Oxford : Pergamon-Elsevier Science Ltd, 2003)
Exopeptidases of Morimus funereus larvae were partially purified and characterized. Specific leucyl aminopeptidase (LAP) activity was increased eight-fold by gel filtration of the crude midgut extract. The partially purified ...
