Integration of engineered cartilage
(Elsevier Sci Ltd, Oxford, 2001)
The structure and function of cartilaginous constructs, engineered in vitro using bovine articular chondrocytes, biodegradable scaffolds and bioreactors, can be modulated by the conditions and duration of tissue cultivation. ...
Factors influencing the removal of divalent cations by hydroxyapatite
(Elsevier, Amsterdam, 2008)
The effect of pH, contact time, initial metal concentration and presence of common competing cations, on hydroxyapatite (HAP) sorption properties towards Ph2+, Cd2+, Zn2+, and Sr2+ ions was studied and compared using a ...
Influence of oxyethylenated alkylamines in the dyeing of polyamide 66 fibres
(Elsevier Sci Ltd, Oxford, 2006)
This paper analyzes the influence of the chemical structure of a series of oxyethylenated laurylamines (LA-EO) on the formation of complexes with the dye C.I. Direct Red 1, as well as on the dyeing kinetics of the polyamide ...
The effects of hemicelluloses and lignin removal on water uptake behavior of hemp fibers
(Elsevier Sci Ltd, Oxford, 2008)
This study investigated the individual influences of hemicelluloses and lignin removal on the water uptake behavior of hemp fibers. Hemp fibers with different content of either hemicelluloses or lignin were obtained by ...
Supercritical carbon dioxide extraction of carrot fruit essential oil: Chemical composition and antimicrobial activity
(Elsevier Sci Ltd, Oxford, 2007)
Isolation of carrot fruit (Daucus carrota L., cultivar "Chanteney") essential oil by supercritical carbon dioxide was investigated from the pretreatment of herbaceous matrix and extraction conditions to the chemical ...
On the role of working fluid properties in Organic Rankine Cycle performance
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The performance of ORC systems strongly depends on working fluid properties. We explore the relationships between working fluid properties and ORC common economic and thermodynamic performance criteria from a theoretical ...
Enzymatic conversion of sunflower oil to biodiesel in a solvent-free system: Process optimization and the immobilized system stability
(Elsevier Sci Ltd, Oxford, 2009)
The feasibility of using the commercial immobilized lipase from Candida antarctica (Novozyme 435) to synthesize biodiesel from sunflower oil in a solvent-free system has been proved. Using methanol as an acyl acceptor and ...
A novel method of preparing the silver chloride cathode for the magnesium seawater activated primary cell
(Journal of Power Sources, 2021)
The novel method based on the inexpensive and fast modified successive ion layer adsorption and reaction (SILAR) method of preparing silver chloride cathode on the carbon felt is developed. The electrochemical behavior of ...
The diffusion of water in poly(ditetrahydrofurfuryl itaconate)
(Elsevier Sci Ltd, Oxford, 2005)
The diffusion of water into solid poly(ditetrahydrofurfuryl itaconate) (PDTFI) films and in analogous polymer solutions was measured. Diffusion into solid PDTFI films on a glass support was measured in three solutions of ...
Corrosion stability of epoxy coatings on aluminum pretreated by vinyltriethoxysilane
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The electrochemical and transport properties and adhesion of epoxy coatings electrodeposited on aluminum pretreated by vinyltriethoxysilane (VTES) were investigated during exposure to 3% NaCl. The VTES films were deposited ...
