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 ...
The photopolymerisation of methacrylic acid by colloidal semiconductors
(Springer, New York, 1994)
Methacrylic acid was photopolymerised using CdS and composite, CdS/HgS and CdS/TiO2, colloidal semiconductor particles as initiators. The previously proposed photoinitiation mechanism involving the photogenerated positive ...
Primena recikliranog vunenog materijala kao sorbenta za uklanjanje nafte, naftnih derivata i ulja iz vode
(Srpsko hemijsko društvo, 2007)
U ovom radu korišćen je sorbent na bazi vune sekundarnog porekla u cilju uklanjanja sirove nafte, dizel goriva, motornog, baznog i biljnog ulja (adsorbata) iz vode. Ispitivan je uticaj različitih obrada sorbenta ...
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 ...
Mass spectrometric study of glassy carbon surface stability
(Serbian Chemical Society, Belgrade, 1996)
The combinaton of temperature-programmed desorption (TPD) and quadrupole mass spectrometry was used to investigate glassy carbon surface stability. TPD experiments provide valuable information about the nature and the ...
Liposomes - Are they adequate delivery system for hemoglobin?
