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 ...
Morphology and capacitive properties of [RuOxHy/low-surface area carbon black] composite materials prepared by sol-gel procedure
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The morphology and the capacitive properties of carbon supported hydrous ruthenium oxide (RuOxHy/C), prepared by impregnation of low-surface area carbon black Vulcano (R) XC-72 R with solid phase of RuOxHy sol, were ...
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 ...
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, ...
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 ...
Low pressure RF capacitively coupled plasma reactor for modification of seeds, polymers and textile fabrics
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Plasma reactor operating at low pressures (0.2-1 Torr) at 13.56 MHz has been developed with an idea to optimize the treatment of polymers, biological and textile materials. The reactor proved very effective in treatment ...
The influence of oxide sol properties on the capacitive behavior of carbon supported hydrous ruthenium oxide
(Progress in Advanced Materials and Processes: Proceedings of the Fifth Jugoslav Materials Research Society, YUCOMAT V, 2004)
Carbon supported hydrous ruthenium oxide was prepared by ail ultrasonic threatment of carbon black-RuOxHy sol mixture (impregnation). Black Pearl 2000(R) was used as a supporting material, while an oxide sol was prepared ...
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 ...
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 ...
