Underpotential deposition of lead on Pt(111) in the presence of bromide: RRDPt(111)E and X-ray scattering studies
(Elsevier Science Sa, Lausanne, 1998)
The underpotential deposition (upd) of Pb onto Pt(lll) in solution containing Br- was examined by classical RRDP(111)E electrochemical methods in combination with in situ surface X-ray scattering measurements. The results ...
Analysis of mass transfer in beer diafiltration with cellulose-based and polysulfone membranes
(Elsevier, Amsterdam, 1997)
An experimental investigation of beer dialysis with transmembrane pressure (diafiltration) was performed using two different hollow-fibre membranes: cuprophane (regenerated cellulose) and polysulfone for different flow ...
Regulation of the crystallization in a crucible furnace
(Elsevier, Amsterdam, 1999)
A model of an air cooler ("cold finger") in a laboratory crucible furnace, for simultaneous regulation of scaling intervals of the crystallization rate in a series of Tamman test tubes with the purpose of obtaining crystals, ...
The potential of the piezoelectric sensor for the characterization of activated carbon cloth applied in the adsorption of phenol from air
(Amer Chemical Soc, Washington, 1996)
Effect of substituents on the C-13 chemical shifts of the azomethine carbon atom of N-(phenyl substituted) pyridine-4-aldimines
(Elsevier, Amsterdam, 1999)
C-13 chemical shifts of the azomethine carbon atom for N-(substituted phenyl)pyridine-4-aldimines, 4-Py-CH=N-C6H4-X, X having a wide range of substituent effects, have been determined in CDCl3 solution. Exceptionally good ...
Electrical resistance of cotton-metal fibre yarns
(Inst Chemical Fibres, Lodz, 1999)
Yarns representing cotton-metal fibre blends were studied. The electrical resistance of yarns including different fractions of cotton and metal fibres was compared with cotton yarns having the same nominal characteristics. ...
Corrosion behaviour of epoxy coatings electrodeposited on steel electrochemically modified by Zn-Ni alloy
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
The corrosion behaviour and thermal stability of epoxy coatings electrodeposited on steel: phosphatised steel and steel previously modified by electrodeposited Zn-Ni alloy was investigated during exposure to 3% NaCl. The ...
Study of thermal stability of epoxy coatings electrodeposited on different substrates
(Elsevier Sci Ltd, Oxford, 1999)
The thermal stability of epoxy coatings electrodeposited on steel, phosphatized steel, steel electrochemically modified by Zn-Ni alloys and aluminium has been investigated. Epoxy coatings were formed by cathodic electrodeposition ...
Rheological study of the copolymerization reaction of acrylate-terminated unsaturated copolyesters with styrene
(Wiley-VCH Verlag Gmbh, Weinheim, 1999)
The free radical copolymerization reaction of three series of acrylate-terminated unsaturated polyesters with styrene, using benzoyl peroxide/N,N-dimethylaniline as the redox initiator system, was followed by dynamic ...
Microstructural characteristics of calcium hydroxyapatite/poly-L-lactide based composites
(Wiley, Hoboken, 1999)
Besides its high osteoinductive properties, hydroxyapatite (HAp) exhibits a relatively low mechanical strength. In order to improve the mechanical properties and reliability of HAp based composites, the addition of selected ...
