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 ...
Influence of the semiconductor doping level on the carrier surface density in an AlGaN/GaN MODFET channel
(Proceedings of the fourth Yugoslav Materials Research Society Conference (YUCOMAT IV), 2002)
In this paper the influence of doping level in AlGaN and GaN on the carriers surface density in a channel of modulation doped field effect transistors (MODFETs) has been investigated. The carriers concentration profile in ...
Nonlinear dynamics of brewing yeast cell growth in alginate micro-beads
(7th Conference of the Yugoslav Materials Research Society - Recent Developments in Advanced Materials and Processes, YUCOMAT VII, 2006)
The nonlinear dynamics of brewing yeast cell growth in porous Ca-alginate matrices is considered experimentally and theoretically. The applications of alginate matrices include the reduction of internal mass transfer ...
The influence of surface modification on related functional properties of wool and hemp
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The new concept of the combined treatment consisting of specific fibre surface tailoring and activation prior to biopolymer or enzyme post-application is introduced. Low-temperature plasma treatment is considered as very ...
Conduction mechanism based model of organic field effect transistor structure
(8th Conference of the Yugoslav Materials Research Society, 2007)
Carriers mobility model of olygomer and polymer semiconductor based OFET (Organic Field Effect Transistor) structures is presented in this paper. Starting from the conduction mechanism in the mentioned organic materials, ...
The activity of iron-containing zeolitic materials for the catalytic oxidation in aqueous solutions
(8th Conference of the Yugoslav Materials Research Society, 2007)
In this work, a series of iron-containing zeolitic materials has been tested as heterogeneous catalysts for decomposition of H2O2 and for oxidation of the cationic dye Methylene Blue with H2O2 in aqueous solutions. FeAPO ...
Fracton scaling and dynamical properties of elastomer materials
(8th Conference of the Yugoslav Materials Research Society, 2007)
Scaling of the real and the imaginary part of dynamic moduli with frequency, for fully cured elastomer materials as gum and active carbon black filled butyl rubbers, is considered experimentally and theoretically. For gum ...
Using the image analysis program for prediction of thermal stability behavior of refractory specimen
(8th International Symposium on Multifunctional and Functionally Graded Materials, FGM2004, 2005)
Most important properties which are usually measured for refractories are work temperature and thermal stability. Thermal stability of the alumina based samples was measured using a standard laboratory procedure, the water ...
Chain conformational statistics and mechanical properties of elastomer composites
(Progress in Advanced Materials and Processes: Proceedings of the Fifth Jugoslav Materials Research Society, YUCOMAT V, 2004)
A new equation of state for elastomer network under constrains due to fillers has been proposed and verified for two most common and industry important rubbers, natural rubber and styrene-butadiene rubber. A series of ...
Damage analysis of particulate polymer composites based structure by using micro-meso-macro finite element approach
(12th International Manufacturing Conference in China, IMCC2006, 2006)
A micro-meso-macro finite element approach has been developed for simulating the macro-scale damage coupled deformation in a particulate polymer composite (PPC) based structure under tension. A damage model for the PPC ...
