Investigation of phase-transformation kinetics in electrodeposited Cu + Cd alloys using anodic linear sweep voltammetry
(Elsevier, 1993)
The anodic linear sweep voltammetry technique was used for a quantitative assessment of the phase composition of Cu + Cd alloys obtained by electrochemical deposition. Current peaks obtained in the voltammograms were ...
X-Ray Analysis in the Optimization of the Sintering Process of SmCo5 Magnets
(Sintering Society, 1997)
The content of the SmCo5 phase, as the carrier of magnetic properties, was controlled by X-ray diffraction analysis. The content of the SmCo5 phase, as a function of sintering time and temperature, under constant heat ...
Photoacoustic properties of softmagnetic amorphous Fe81B13Si4C2 ribbon
(Springer, 1998)
Photoacoustic properties of amorphous Fe81B13Si4C2 ribbons were investigated. The amplitude and phase photoacoustic spectra were measured as a function of the modulation frequency of an He–Ne laser beam. Thermal diffusivity ...
Mathematical modelling and simulation of drawing thin glass sheet from a rectangular preform
(Society of Glass Technology, 1998)
A mathematical model of thin glass sheet drawing has been developed. This model includes momentum, heat and mass balance equations. The density, viscosity and specific heat of the glass were calculated as functions of ...
Exposure of Mn and FeSODs, but not Cu/ZnSOD, to NO leads to nitrosonium and nitroxyl ions generation which cause enzyme modification and inactivation: an in vitro study
(Elsevier, 1999)
The effect of NO treatment in vitro on structural and functional alterations of Cu/Zn, Mn, and Fe type of
SODs was studied. Significant difference in response to NO of Cu/ZnSOD compared to the Mn and Fe types was
demonstrated. ...
Opening of the Macrocyclic Ring in 5,10:8,9‐Disecosteroids ( = Steroklastanes)
(Weinheim : Wiley-VCH Verlag GmbH & Co., 1992)
Catalytic hydrogenation of the Δ3‐unsaturated (9R,10 R)‐ and (9S,10 S)‐epoxyenol lactones 3a, b., and 4a, b., respectively, affords, in addition to the expected saturated epoxylactones 5a, b and 7a, b, also open‐chain ...
Корунд из дистенско-силиманитског шкриљца Боболош-Брза Паланка
(Geoinstitut, 1994)
Korund iz distensko silimanitskog škriljca lokalnosti Bobološ je detaljnije mineraloško-kristalografski ispitan pomoću nekoliko metoda. Dobijeno je učešće korunda od oko 15 %, čime je ova stena postala značajna kao sirovina ...
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 ...
13,14-Seco-steroids: A New Type of Modified Steroids Containing a Nine-Membered Ring
(Wiley, 1999)
Oxidations of 14α‐hydroxy‐5α‐cholestan‐3β‐yl acetate (5) with lead tetraacetate under thermal or photolytic conditions or in the presence of iodine proceed mainly by fragmentation of the C(13)−C(14) bond to give as the ...
