Structural investigation of the chabazite like aluminophosphate prepared in the presence of HF.
(Amer Chemical Soc, Washington, 1997)
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 ...
Bi adsorption on Pt(111) in perchloric acid solution: A rotating ring-disk electrode and XPS study
(Royal Soc Chemistry, Cambridge, 2000)
The surface electrochemistry of reversibly and irreversibly adsorbed bismuth (Bi-ad) was studied on Pt(111) electrodes in 0.1 M HClO4. The valence state of irreversibly adsorbed Bi (Bi-ir) was determined by ex situ X-ray ...
Examination of rheological properties of fine particle dispersions as carriers for controlled drug release
(Trans Tech Publications Ltd, Durnten-Zurich, 1998)
The rheological characteristics of various systems made by mixing blood, blood serum, and drug carriers, as liposomes, lipid emulsion and polymer latex (model system for nano- particles) are reported as function of shear ...
Theoretical assessment of calcium arsenates stability: Application in the treatment of arsenic contaminated waste
(8th Conference of the Yugoslav Materials Research Society, 2007)
Several approaches for immobilization of arsenic (As) based on the transformation of its soluble forms (compounds) into highly insoluble arsenate apatite Ca5(AsO4)3 OH have been proposed. These immobilization techniques ...
Relationship between Mechanical Characteristics and Thermal Shock Behaviour of Alumina Based Refractories
(InterCeram: International Ceramic Review, 2003)
The thermal stability of the refractory material with the Al 2 O 3 content of 42 mass-% was investigated. Water quench tests (JUS.B.D8.319.) were carried out. The dynamic Young modulus of elasticity was calculated using ...
Influence of drying constant and diffusivity on clay drying behavior
(Techna Srl, Faenza, 2007)
The influence of the correlation between the drying constant and the diffusion coefficient of the liquid on the behavior of two raw materials for brick manufacturing during their drying process was examined. The test was ...
Leaching kinetics of lead from lead (II) sulphate in aqueous calcium chloride and magnesium chloride solutions
(Elsevier Science Bv, Amsterdam, 1997)
The kinetics of lead leaching from lead (II) sulphate in aqueous calcium chloride and magnesium chloride solutions was studied. The leaching rates of lead were measured by using an agitated vessel at atmospheric pressure, ...
Selection of Calculation Method for Temperature Distribution in 99 Mass-% Al 2 O 3 Refractories
(Verlag Schmidt GmbH, 1998)
Refractories are constantly exposed to temperature changes. In most cases this exposure causes damage. In this work, attention is paid to problems of non-steady-state heat transfer. Some analytical and numerical methods ...
Correlation between apparent activation energy for hot working and temperature of no recrystallization in microalloyed steels
(Trans Tech Publications Ltd, Durnten-Zurich, 2003)
Two-stage linear ln[sinh(as)] vs 1/T plots, based on the stress data derived from either continuous or multipass flow curves generated by testing low carbon Nb/Ti microalloyed steel (Nb steel) and medium carbon V-microalloyed ...
