Surface characteristics and modification of different carbon materials
(7th Conference of the Yugoslav Materials Research Society - Recent Developments in Advanced Materials and Processes, YUCOMAT VII, 2006)
In this work, surface characteristics of different carbon materials were investigated. The materials under consideration were: activated carbon, carbon monolith, carbon felt and glassy carbon (powder, plate and broken ...
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. ...
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 ...
Formation mechanism, morphology and synthesis of alpha-Al2O3, mullite and cordierite particles obtained by the ultrasonic spray pyrolysis
(Trans Tech Publications Ltd, Durnten-Zurich, 1996)
The present stage in our investigations of the synthesis of high-purity, submicrometer and spherical Al2O3, mullite and cordierte powders obtained by the ultrasonic spray pyrolysis is presented. The influence of precursors ...
Stress state effect on dynamic strain aging and surface markings during stretching of AlMg7 alloy sheet
(Trans Tech Publications Ltd., 1998)
Stress state effect on dynamic strain aging (DSA) and the related surface appearance was analyzed in uniaxial and biaxial room temperature stretching of AlMg7 alloy sheet. In uniaxial tension the serrated yielding was found ...
Scaling of network segment dimensions in hyperelastic composites
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The change in elastomer tensile moduli, as formulated in the Gaussian statistical theory of rubber elasticity, with deformation, is considered both experimentally and theoretically. Gum elastomers of different structures ...
Comparative potentiodynamic study of nickel and hydrogen underpotential deposition at polycrystalline platinum electrode in weak acid and neutral solutions
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Underpotential deposition of nickel and hydrogen on polycrystalline platinum in weak acid and neutral solutions (3.5 lt = pH lt = 7.0), with and without Ni2+-ions, has been examined using cyclic voltammetric technique ...
Emulsion stability evaluation using fractal dimensions approach
(8th Conference of the Yugoslav Materials Research Society, 2007)
There are many developed strategies for evaluating emulsion stability, aimed at determining the life circle of emulsions. Most of them are based on rheological properties of emulsions. There are, however, very few based ...
Alginate microbeads as potential support for cultivation of bone marrow stromal cells
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Alginate is currently being employed and explored for a broad range of biomedical and biotechnology applications, due to its biodegradability and simple procedure for cell immobilization. However, cell immobilization was ...
Mathematical modeling of cell distribution in alginate microbeads
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Alginate is one of the mostly used hydrogels for cell entrapment aimed for applications in food industry, environmental engineering, pharmacy and biomedicine. One of the major parameters affecting cell viability and activity ...
