Electrodeposited hydroxyapatite thin films modified by ion beam irradiation
(Natl Inst Optoelectronics, Bucharest-Magurele, 2009)
Surface modification of hydroxyapatite (HA) thin films electrodeposited on titanium was conducted by ion implantation, using nitrogen and argon ions at different constant fluences of 1x10(15), 1x10(16) and 1x10(17) ions/cm(2). ...
Influence of microstructure and phase composition on the nanoindentation characterization of bioceramic materials based on hydroxyapatite
(Elsevier Sci Ltd, Oxford, 2009)
The aim of the study was to investigate the influence of microstructure and phase composition on the mechanical behaviour of hydroxyapatite (HAp) and biphasic HAp/beta-tricalcium phosphate (beta-TCP) bioceramic materials ...
Sol-Gel Combustion Synthesis of La-9.33(SiO4)(6)O-2 Oxyapatite
(Taylor & Francis Inc, Philadelphia, 2009)
Synthesis of La-9.33(SiO4)(6)O-2 was performed by a new method that represents the combination of sol-gel and combustion procedures using glycine as the fuel. Syntheses were performed from ethanol-water solutions of oxides ...
Catalytic Degradation Processes and Swelling of Alginate Bio-Medical Gels under Influence of Oxygen
(Taylor & Francis Inc, Philadelphia, 2009)
Interaction of cells with polymer networks in nanostructured devices as alginate beads for cell immobilization are considered. Influence of process parameters as oxygen concentration inside a bead on changes of alginate ...
Preparation of Silver(I) Complexes with Itaconic Acid-Based Hydrogels for Biomedical Application
(Taylor & Francis Inc, Philadelphia, 2009)
Silver(I) complexes based on itaconic acid hydrogel were prepared and characterized in order to examine the potential use of these materials. FTIR, AFM, in vitro fluid-uptake, metal sorption, and antibacterial activity ...
Plasma-induced Decolorization of Indigo-dyed Denim Fabrics Related to Mechanical Properties and Fiber Surface Morphology
(Sage Publications Ltd, London, 2009)
The aim of this study was to investigate how morphology of fibers is affected by plasma during the process of decolorization by a low-pressure RF plasma (gas, treatment time, and power were varied) and atmospheric pressure ...
