Nanotribological properties of UHMWPE/quartz composites
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Wear of ultra-high molecular weight polyethylene (UHMWPE) and its composites is one of the main obstacles that limit the longevity of total joint replacements. Compression molded UHMWPE/quartz composites with organosiloxane ...
Cell support studies aimed for cartilage tissue engineering in perfused bioreactors
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
Cartilage tissue engineering based on chondrogenic cells seeded onto biodegradable polymer supports and cultivated in bioreactors can potentially become an effective method for creating functional tissue equivalents. ...
Immobilization/encapsulation of cells using electrostatic droplet generation - Experiments and theory
(Minerva Biotecnologica, 2000)
The mechanism of alginate droplet formation as well as experimental parameters for producing very small polymer microbeads (i,e, less then 100 microns diameter) using an electrostatic droplet generator were investigated, ...
Alginate microbeads as a cell support for cartilage tissue engineering: Bioreactor studies
(8th Conference of the Yugoslav Materials Research Society, 2007)
Alginate was shown to be a suitable support for entrapment and cultivation of chondrocytes and bone marrow stromal cells, which under appropriate in vitro conditions synthesized cartilaginous components. The main limitation ...
Artificial neural network data analysis for classification of soils based on their radionuclide content
(Maik Nauka/Interperiodica/Springer, New York, 2007)
The artificial neural network (ANN) data analysis method was used to recognize and classify soils of an unknown geographic origin. A total of 103 soil samples were differentiated into classes according to the regions in ...
Study of chlorination of nickel ferrite by gaseous chlorine and calcium chloride in the presence of active additives
(Wiley, Hoboken, 2000)
Thermodynamic analysis and experimental research of the chlorination of nickel ferrite (NiFe2O4) by gaseous chlorine in the presence of added C, BaS, S and NaCl in the temperature range from 300 to 900 degrees C are given ...
Surface characterization of keratin fibres treated by water vapour plasma
(Wiley, Hoboken, 2003)
The effect of water vapour plasma treatment on the shrinkage behaviour and chemical properties of the surface of keratin fibres was studied. The wettability and shrink resistance of wool were improved even at low plasma ...
Acceptability of Residual Stresses Measurement Methods of Butt Weldments and Repairs
(Strojarstvo, 2009)
The joints made by fusion of materials are exposed to the influence of residual stresses induced by welding thermal cycles. Residual stresses were measured on butt welded plates made of NIOMOL 490K, before and after ...
Material properties and thermal shock behavior of alumina based refractories
(Belgian Ceramic Soc, Mons, 2001)
Materials were five alumina based commercial refractories with different contents of ( Al2O3 + TiO2) from 28 % to 78 %. Thermal and mechanical properties of the chosen materials, were measured using standard laboratory ...
Applicability of cubic equation of state mixing rules on correlation of excess molar volume of non-electrolyte binary mixtures - Part II
(Taylor & Francis Ltd, Abingdon, 2006)
The excess molar volume (V-E) data of the 24 binary highly non-ideal mixtures containing dicyclic ethers ( 593 data points) were correlated by the Peng - Robinson - Stryjek - Vera (PRSV) cubic equation of state (CEOS) ...
