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 ...
Oxygen reduction on a duplex stainless steel
(Oxford : Pergamon-Elsevier Science Ltd, 1998)
O-2 reduction on duplex stainless steel was investigated in neutral and alkaline solutions with and without the presence of chloride ions. All polarization curves showed hysteresis with higher reaction rate in positive ...
Mineraloške i kristalografske karakteristike silikata iz skarnova lokalnosti Meka Presedla - Mrkonje na Kopaoniku
(Beograd : Prirodnjački muzej, 1992)
Different silicate minerals occurring in the skarn rocks of Meka Presedla-Mrkonje locality at the central Kopaonik Mt., have been investigated by chemical, IR spectroscopic and X-ray powder diffraction methods. According ...
Far infrared properties of PLZT ceramics
(Springer, 1997)
Far infrared and mid-infrared reflectivity measurements have been made of lead titanate zirconate (PLZT) ceramics at room temperature in the frequency range 40–1500 cm-1. Kramers-Krönig analysis and a fitting procedure ...
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 ...
Electrochemical activation of the electroless deposition of Ni–P alloy and phase structure characterization of the deposit. Part I: Dual bath system
(Springer, 1999)
A typical low temperature alkaline bath was chosen for the investigation of the effect of electrochemical activation on the efficiency of the electroless deposition of Ni and on the phase structure of the Ni–P alloys ...
Phase-structure analysis of brass by anodic linear-sweep voltammetry
(Springer, 1992)
Anodic linear-sweep voltammetry (ALSV) was applied to electrodeposited alloy layers and to metallurgically obtained Cu−Zn alloys of different composition and structure. Metallurgically obtained samples covered the range ...
Sinterovani magneti tipa SmCo5
(Savez inženjera metalurgije Srbije, 1997)
U toku istraživanja tehnološkog postupka sinterovanih magneta tipa SmCo5 i izrade laboratorijskog modela definisani su tehnološki parametri za svaku fazu postupka dobijanja. Za izradu SmCo5 magneta korišćene su tehnike ...
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 ...
