Liposomes with alpha-tocopherol membrane
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 1996)
Liposomes, closed spherical structures formed by phospholipid bilayers, have been recognized as a controlled drug delivery system. We have studied the preparation and biocompatibility of liposomes based on soya phospholipids ...
Surface electrochemistry of CO on Pt(110)-(1x2) and Pt(110)-(1x1) surfaces
(Elsevier Science Bv, Amsterdam, 1997)
A new type of flame-annealing method has been developed for the preparation of surfaces having either fcc(110)-(1x1) or fcc(110)-(1 x 2) symmetry. In situ X-ray scattering studies show that both the Pt(110)-(1 x 2) and ...
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. ...
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)
Synthesis of nanostructured mullite from xerogel and aerogel obtained by the nonhydrolytic sol-gel method
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
Synthesis and nanostructure evolution of mullite (3Al(2)O(3).2SiO(2)) from xero- and aerogels, obtained by the non-hydrolytic sol-gel process are described. Mullite crystallization and gel nanostructure evolution after ...
Corrosion protection of aluminium by a cataphoretic epoxy coating
(Elsevier Science Sa, Lausanne, 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 ...
Simultaneous presentation of VLE, H-E and c(p)(E) by the PRSV equation of state with the modified van der Waals one-fluid and Huron-Vidal-Orbey-Sandler mixing rules
(Elsevier, Amsterdam, 1999)
The Stryjek-Vera modification of the Peng-Robinson equation of state with two parameter van der Waals one-fluid mixing rule suggested by Schwartzentruber and Renon (SR) and the Orbey-Sandler modification of the Huron-Vidal ...
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 ...
