Corrosion protection of aluminium by a cataphoretic epoxy coating
(Elsevier, 1999)
The corrosion behavior and thermal stability of epoxy coating electrodeposited on aluminium have been investigated during exposure to
3% NaCl. Electrochemical impedance spectroscopy (EIS), gravimetric liquid sorption ...
Electron‐impact induced decomposition of some 3‐alkyl‐5‐substituted‐6‐methyl uracils
(John Wiley & Sons, 1995)
Mass spectrometry was used to study the main fragmentation routes of some 3‐alkyl‐5‐substituted‐6‐methyl uracils. Differences in fragmentation were caused by changes in the structure of the alkyl group in position 3 of the ...
Oxidation products of hyperforin from Hypericum perforatum
(Elsevier, 1998)
The isolation of two oxidation products of hyperforin from the aerial parts of Hypericum perforatum and their structure determination by means of 2D NMR methods is reported. The products had the same 1-(2-methyl-1- ...
Oxidation of carbon monoxide over Cu1-xCrxCo2O4 in the presence of sulfur oxides
(Springer, 1991)
Carbon monoxide oxidation activity and aging of Cu1-xCrxCo2O4 (0<x<1) spinels in the presence of sulfur oxides have been studied. The results obtained indicate that the sulfur tolerance is related to the presence of ...
Covalent glycophospholipid binding to hemoglobin. A new post-translational modification occurring in erythrocytes exposed to insulin
(Serbian Chemical Society, 1996)
In this work a novel hitherto unrecognised hemoglobin (Hb) fraction, HbA1x, which we detected previously in hemolysates of erythrocytes exposed to high concentration of insulin under hypoglycemic conditions, both in vivo ...
Degradative side reactions in the syntheses of exactly alternating silarylene-siloxane polymers
(Springer, 1992)
Four principal synthetic methods for preparation of exactly alternating silarylene-siloxane polymers: the chlorosilane, the acetoxysilane, the aminosilane and the ureidosilane polymerization reactions, were compared under ...
An improved approach to B-norsteroids: An one-pot preparation of 3β-acetoxy-5-oxo-5,6-seco-cholestan-6-oic and 3β-acetoxy-5,17-dioxo-5,6-seco-androstan-6-oic acids
(Serbian Chemical Society, 1998)
A simple one-put procedure for the synthesis of the 5,6-seco-steroidal acids 9a,b in described in this paper. It consists of the epoxidation of the ▲ 5 -steroids, i.e., cholesteryl acetate (8a) and 17-oxo-aandrost-5-en-3β-yl ...
Functionalized oligopolysiloxanes by heterogeneously catalyzed equilibration polymerization reactions
(Springer, 1995)
A new general procedure for preparation of functionalized oligopolysiloxanes of predetermined molecular weight is described. It utilizes heterogeneously catalyzed siloxane equilibration polymerization reactions which do ...
Essential oil of achillea coarctata
(Taylor & Francis, 1999)
Essential oil of Achillea coarctata Poir. was investigated for yield and composition. Sixty identified compounds in the oil constituted 79-3% of the oil. The main compounds of the oil were: caryophyllene oxide (9.0%), ...
A simple approximative method for determination of Auger 1 lifetime in degenerate narrow gap semiconductors
(Elsevier, 1993)
Using the well-known Beattie-Landsberg expression for Auger 1 lifetime and the “effective” Auger energy gap (EgA), we obtained a simple approximative expression for determination of the Auger 1 lifetime. We also obtained ...
