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 ...
Modeling of nanostructural design of ultrafine mullite powder particles obtained by ultrasonic spray pyrolysis
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
In this paper, a model of substructure design of mullite powder particles obtained by spray pyrolysis lit the field of ultrasound excitation is described. Based an this model, the size of subparticles (nanoparticles) ...
The homogeneous photopolymerization of methyl methacrylate by colloidal cadmium sulfide
(Wiley-VCH Verlag Gmbh, Weinheim, 1994)
A completely new method of initiating the homogeneous radical polymerization of methyl methacrylate in bulk or in solution via the photogeneration of an electron hole pair in colloidal cadmium sulfide is presented. A ...
The time dependence of chitosan nonionic surfactant solution viscosity
(Dr Dietrich Steinkopff Verlag, Berlin 33, 1996)
The measurement of the viscosity of semiconcentrated chitosan (0.08-0.14%) solutions in the system with octaethyleneglycol mono n-dodecylether (C(12)E(8)) was carried out using Cannon-Fenske capillary viscometer. The ...
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 ...
On the thermolysis of poly(chloroalkyl methacrylates) and poly(chloroalkyl acrylates): Part 1-Poly(2,2,2-trichloroethyl methacrylate)
(Elsevier Sci Ltd, Oxford, 1991)
The thermal degradation of poly(2,2,2-trichloroethyl methacrylate). PTCMA, in the absence and presence of O2 was studied and compared with that of poly(ethyl methacrylate), PEMA. In the absence of O2 the two polymers behaved ...
The flow of the viscous fluid around the sphere in the range Re {similar or less-than} 2
(Springer Wien, Wien, 1992)
An improved and more correct solution of Oseen's equations, when the flow of the incompressible viscous fluid around the sphere is concerned, has been suggested. The new Oseen's correction term of the Stokes solution for ...
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 ...
Liposomes - Are they adequate delivery system for hemoglobin?
(Elsevier Science Inc, New York, 1996)
Electrooxidation of H-2, CO and H-2/CO mixtures on a well-characterized Pt-Re bulk alloy electrode and comparison with other Pt binary alloys
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
We report new results for the electrooxidation of Hz, CO and H-2/CO mixtures on a Pt75Re25 bulk alloy using surface preparation in a UHV chamber and characterization by X-ray photoelectron spectroscopy (XPS). Sputter-cleaned ...
