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 ...
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 ...
Theoretical assessment of calcium arsenates stability:Application in the treatment of arsenic contaminated waste
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
Several approaches for immobilization of arsenic (As) based on the transformation of its soluble forms (compounds) into highly insoluble arsenate apatite Ca-5(AsO4)(3)OH have been proposed. These immobilization techniques ...
The influence of low-temperature plasma and enzymatic treatment on hemp fabric dyeability
(Inst Chemical Fibres, Lodz, 2007)
In order to study the influence of low-temperature air plasma and enzymatic treatment on the dyeing properties of hemp, "cold dyeing" of hemp fabric with acid dye (C.I. acid blue 113) and direct dye (C.I direct red 81) was ...
Sintering behaviour of nanosized HAP powder
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
The influences of temperature and time on sintering behaviour of nanosized HAP powder were investigate in this paper. The calcium hydroxyapatite powder, with the average crystallite size of 34 +/- 1 nm, was uniaxially ...
Levels of PAHs in the soils of Belgrade and its environs
(Springer, Dordrecht, 2007)
Polycyclic aromatic hydrocarbons (PAHs) were analysed in 39 soil samples (0-10 cm upper layer) collected in Belgrade, the capital of Serbia. The sampling sites were randomly selected from urban, urban/recreational and rural ...
Decomposition of methomyl over supported iron catalysts
(Springer, Dordrecht, 2007)
Catalytic wet peroxide oxidation of methomyl over Fe-ZSM-5 and AlFe-pillared montmorillonite was carried out at room temperature, in a glass batch reactor, under constant airflow and halogen lamp light. Both catalysts have ...
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 ...
Modeling and investigation of SiGe based MOSFET structure transport characteristics
(8th Conference of the Yugoslav Materials Research Society, 2007)
The focus of this paper was the investigation and modeling of transport characteristics in a strained SiGe based MOSFET structure, which might be of fundamental importance for the understanding of its operating characteristics. ...
Osmotic and activity coefficients of {yKCl+(1-y)MgCl2}(aq) at T=298.15 k
(Springer/Plenum Publishers, New York, 2007)
Isopiestic vapor-pressure measurements were made at the temperature 298.15 K for aqueous KCl + MgCl2 solutions using KCl(aq) as the reference standard. The measurements for these ternary solutions were made at KCl ionic ...
