Nonlinear properties and stability of SnO2 varistors prepared by evaporation and decomposition of suspensions
(Elsevier Sci Ltd, Oxford, 2005)
SnO2 varistors doped with CoO, Cr2O3 and Nb2O5 were prepared by evaporation and decomposition of suspensions. The composition of the varistors was optimized to improve electrical properties, such as nonlinearity, leakage ...
Glycosaminoglycan deposition in engineered cartilage: Experiments and mathematical model
(Wiley-Blackwell, Malden, 2000)
Functional cartilaginous constructs for scientific research and eventual tissue repair were cultivated in bioreactors starting from chondrocytes immobilized on polymeric scaffolds. The scaffolds gradually degraded as the ...
Effect of temperature on the excess molar volumes of some alcohol plus aromatic mixtures and modelling by cubic EOS mixing rules
(Elsevier, 2006)
Densities of the (methanol + benzene), (ethanol + benzene), (methanol + chlorobenzene) and (ethanol + chlorobenzene) mixtures have been measured at six temperatures (288.15, 293.15, 298.15, 303.15, 308.15 and 313.15 K) and ...
Kinetics of sunflower and used vegetable oil methanolysis catalyzed by CaO·ZnO
(Elsevier Sci Ltd, Oxford, 2013)
The kinetics of heterogeneous methanolysis of sunflower oil and used vegetable oil were studied at different temperatures, ranging from 60 to 96 degrees C using CaO center dot ZnO as catalyst (2 wt% on the basis of oil) ...
Influence of hemicelluloses and lignin content on structure and sorption properties of flax fibers (Linum usitatissimum L.)
(Springer, Dordrecht, 2018)
In this work, alkali and oxidative treatments were employed to obtain flax fibers with different content of hemicelluloses and lignin, in order to study the influence of chemical composition on structure and sorption ...
Spray drying of Gentiana asclepiadea L. root extract: Successful encapsulation into powders with preserved stability of bioactive compounds
(Industrial Crops and Products, 2021)
Willow gentian as a source of bitter compounds is traditionally used for digestive disorders. Gentiana root extract was spray dried using five different carriers (maltodextrin, whey protein, pectin, starch, gelatine) at ...
Electrochemical testing of noble metal dental alloys: The influence of their chemical composition on the corrosion resistance
(Corrosion Science, 2021)
Platinum and nine commercial dental alloys with the contents of noble metals ranging from 27 wt.% to 97.6 wt. % were investigated by the procedure described in the Standard ISO 10271:2009, Electrochemical testing was ...
Dynamic cell seeding of polymer scaffolds for cartilage tissue engineering
(Wiley, Hoboken, 1998)
Cell seeding of three-dimensional polymer scaffolds is the first step of the cultivation of engineered tissues in bioreactors. Seeding requirements of large scaffolds to make implants for potential clinical use include: ...
Study of interaction between nitrogen DBD plasma-treated viscose fibers and divalent ions Ca2+ and Cu2+
(Springer, Dordrecht, 2014)
Viscose fibers were treated with atmospheric pressure dielectric barrier discharge (DBD) plasma obtained in nitrogen in order to activate the fiber surface prior to sorption of the divalent ions Ca2+ and Cu2+. Methylene ...
Immobilization of yeast cells in PVA particles for beer fermentation
(Elsevier Sci Ltd, Oxford, 2007)
In this study, the potential of application of non-aggressive LentiKat (R) technique for brewer's yeast immobilization on polyvinyl alcohol was assessed. High cell loads of about 109 cells/ml were achieved by this procedure ...
