Size distribution of ultrafine spherical ceramic powders obtained by ultrasonic spray pyrolysis
(Trans Tech Publications Ltd., 1997)
Comparative analysis of experimentally determined particle size distribution and theoretically calculated aerosole drop size distribution (obtained on the basis of 3D model of spherical / elliptical waves generated by the ...
Recent advances in homogeneous and heterogeneous asymmetric catalysis with nitrogen-containing ligands
(Baltzer Sci Publ Bv, Bussum, 1997)
Nitrogen-containing chiral ligands are being used more and more in asymmetric catalysis. This article is an overview of results published in 1993-1996 in this field and tries to open new perspectives for this type of ligand, ...
Application of a chitosan/nonionic surfactant mixture to wool assessed by dyeing with a reactive dye
(Society of Dyers and Colourists, 1997)
Chitosan application to wool is known to be associated with problems such as its weak binding and uneven distribution. In an attempt to overcome such problems, chitosan was applied from a mixture with a nonionic surfactant. ...
Corrosion protection of mild steel by polypyrrole coatings in acid sulfate solutions
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
The corrosion behaviour of mild steel covered by the electrodeposited polypyrrole films was investigated by electrochemical impedance spectroscopy. Electrodeposition of polypyrrole was performed from aqueous solution of ...
Thermal shock of ceramic material : Damage resistance parameters and critical flaw size
(Trans Tech Publications Ltd., 1997)
The alumina refractories used in this study included a serias of 12 commertial products (two fireclay and ten high alumina brands ) containing ≈ 45 - 90 % Al2O3. Damage resistance parameters R,, R, and RSt were used in ...
Reaction of a new thiol cationic surfactant with bunte salt in wool fibers
(Textile Research Inst, Princeton, 1997)
A new, effective, specific quaternary ammonium compound, N-dodecyl-amino-betaine-2-mercaptoethylamine hydrochloride (DABM), is synthesized to confer permanent characteristics (antimicrobial properties, improved dyeing and ...
Underpotential deposition of lead on Pt(111) in perchloric acid solution: RRDPt(111)E measurements
(Amer Chemical Soc, Washington, 1997)
Underpotential deposition (UPD) of lead (Pb-upd) on Pt(111) in perchloric acid solution was studied using the rotation ring disk, electrode (RRDPt(111)E) method for measurements of the Pb2+ ion-specific flux. The total ...
Liposomes as carriers of antimicrobial drugs
(Taylor & Francis Ltd, Abingdon, 1997)
Liposome are promising drug carrier systems being developed. Their successful use in the treatment of several diseases demonstrates that a solid rationale for clinical development of liposomes as antimicrobial drug carriers ...
Boron and phosphorus doped glassy carbon: I. Surface properties
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
The effects of boron and phosphorus incorporation in phenolic resin precursor on the surface properties of glassy carbon (GC) have been studied. Characterization of the surface properties using X-ray photoelectron spectroscopy ...
Synthesis of spinel powders by the spray pyrolysis method
(Trans Tech Publications Ltd, Durnten-Zurich, 1997)
In this paper synthesis of spinel powders by the two-fluid spray pyrolysis method was performed. The influence of the precursors (AlCl3·9H2O and MgCl2·6H2O for S-1 powder and boehmite sol and MgCl2·6H2O for S-2 powder) on ...
