Swelling and drug release behavior of poly(2-hydroxyethyl methacrylate/itaconic acid) copolymeric hydrogels obtained by gamma irradiation
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
The new copolymeric hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) were prepared by gamma irradiation, in order to examine the potential use of these hydrogels in controlled drug release ...
Incorporation of poly(N-isopropylacrylamide)/chitosan microgel onto plasma functionalized cotton fibre surface
(Elsevier, Amsterdam, 2009)
In the present study, non-thermal plasma treatments using three different gases (air, nitrogen and argon) were used to activate the cotton surface for subsequent poly(N-isopropylacrylamide)/chitosan microgel (PN/CS) ...
The influence of steel surface modification by electrodeposited Zn-Fe alloys on the protective behaviour of an epoxy coating
(Elsevier Science Sa, Lausanne, 2003)
The electrochemical and transport properties of epoxy coatings electrodeposited on steel and steel modified by Zn-Fe alloys were investigated during exposure to 3% NaCl. The Zn-Fe alloys were deposited on steel surface ...
Influence of the background electrolyte on the point of zero charge of chromium(III)-oxide
(Trans Tech Publications Ltd, Durnten-Zurich, 2003)
The Point of zero charge of chromium(Ill)-oxide (pH(pzc)) was investigated by a batch equilibration method. The effect of several background electrolytes, in the concentration range of 10(-5)-10(-1) mol/dm(3), on pH(pzc) ...
The nucleation behavior of k2o center dot tio2 center dot 3geo(2) undercooled melt
(University of Chemistry and Technology, Prague, 2009)
The nucleation of K2TiGe3O9 crystals in an undercooled melt of stoichiometric composition was studied. Volume nucleation with spherical morphology of the growing crystals was determined. The nucleation range is in the ...
Swelling and thermodynamic studies of temperature responsive 2-hydroxyethyl methacrylate/itaconic acid copolymeric hydrogels prepared via gamma radiation
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
The copolymeric hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) were synthesized by gamma radiation induced radical polymerization. Swelling and thermodynamic properties of PHEMA and copolymeric ...
Nonlinear FR-ZLC method for investigation of adsorption equilibrium and kinetics
(Springer, New York, 2008)
A new method for investigation of adsorption equilibrium and kinetics, named Nonlinear Frequency Response-Zero Length Column (NFR-ZLC) method, is introduced. It combines the advantages of the Nonlinear FR method (the ...
Novel approach to the investigation of carriers' concentration in various semiconductor structures
