A study of the tetrahallogenonickel(II) complexes by the Fenske-Hall molecular orbital method
(Society of Chemists and Technologists of Macedonia, 1995)
The coordination geometry and electronic structure of the NiX4(2-) complex ions (X=Cl, Br, I) have been studied by the Fenske-Hall SCF method. The calculation confirm the presence of tetrahedral over square-planar geometry. ...
Electrolyte penetration through epoxy coatings electrodeposited on steel
(Pergamon-Elsevier Science Ltd, Oxford, 1995)
A.C. impedance measurements carried out on epoxy-resin elcctrocoated steels were used to determine the pore resistance of the organic film as a function of time of exposure to 3% sodium chloride solution. The thermogravimctric ...
Influence of substrate on the formation and growth kinetics of cathodic electrocoat paint
(Elsevier Science Sa, Lausanne, 1995)
Cataphoretic deposition of an epoxy primer was carried out on four different substrates: bare steel; phosphated steel; bare zinc-plated steel; and phosphated zinc-plated steel. Film growth was followed by observing the ...
Electron‐impact induced decomposition of some 3‐alkyl‐5‐substituted‐6‐methyl uracils
(Wiley, Hoboken, 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 ...
Hydrodynamics and Mass Transfer in a Four‐Phase External Loop Air Lift Bioreactor
(Wiley, Hoboken, 1995)
An external loop air lift reactor (ELALR) was developed and designed for continuous production and extraction of extracellular secondary metabolites by immobilized Frangula alnus Mill. plant cells. This system was considered ...
Production of anthraquinones by immobilized Frangula alnus Mill. plant cells in a four-phase air-lift bioreactor
(Springer, New York, 1995)
The production of anthraquinones by Frangula alnus Mill. plant cells was used as a model system to evaluate the performance of a liquid-liquid extractive product-recovery process. The shake flask experiments have shown ...
Chaerophyllum coloratum L.: Essential oils of ripe fruits and umbels
(Taylor & Francis, 1995)
Poly(dialkoxyethyl itaconate)s-I. Some properties of dimethoxyethyl itaconate and its polymer
(Pergamon-Elsevier Science Ltd, Oxford, 1995)
The preparation of dimethoxyethyl itaconate and its polymerisation are described. Some of the properties of the monomer and polymer were determined with special emphasis on the experimental determination of the solubility ...
Cobalt(II)-exchange in Zeolite A
(Akadémiai Kiadó, 1995)
The influence of the initial Co(2+) and Na(+) concentrations (Co(Co) and Co(Na), respectively) upon the exchange degree (y) of Na(+) by Co(2+) ions in Zeolite A at 20 oC has been studied. The observed increase of y with ...
A novel open-framework sodium zincophosphate with isomorphous cobalt(II) substitution
(Royal Society of Chemistry, 1995)
A novel anionic cobalt-substituted zincophosphate framework with a hexagonal unit cell of composition Na6[Co0.2Zn0.8PO4]6·9H2O is synthesised and its crystal structure determined by single crystal X-ray diffraction.
