Investigation of antimicrobial activity of encapsulated essential oils
(8th Conference of the Yugoslav Materials Research Society, 2007)
Antimicrobial activity of essential oils obtained from many plants has been known for a long time. However, the use of essential oils as active components of biomedical textile have recently gained popularity and aroused ...
Numerical and analytical modeling of elastic-plastic fracture mechanics parameters
(8th Conference of the Yugoslav Materials Research Society, 2007)
Structural integrity and service reliability depend on the fracture resistance of a material. Cracks in the material are the locations of stress concentration, and elastic-plastic deformation can occur causing the development ...
Influence of Cu on the mechanical properties of an Al-4.4wt%Mg alloy after ECAP
(Trans Tech Publications, Ltd., 2006)
Two Aluminium alloys, type AA5182 and AA5182+1.2wt% Cu, have been studied. The
second alloy in solution treated condition is 18% stronger than the first one. During ageing at 150°C or 200°C it shows a characteristic fast ...
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 ...
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 ...
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 ...
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 ...
