Finite element modeling of mechanical properties of particulate composite biomaterials
(Proceedings of the fourth Yugoslav Materials Research Society Conference (YUCOMAT IV), 2002)
The influence of inclusion geometry and volume fraction on stiffness behavior of a particle hydroxyapatite filled polymer (poly-L-lactide and collagen) matrix composite was investigated by finite element. analysis. The ...
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 ...
Release and diffusion studies of hydrogels based on itaconic acid
(8th Conference of the Yugoslav Materials Research Society, 2007)
Controlled release studies of drugs (theophylline (TH), fenethylline hydrochloride (FE) and gentamicin sulphate (GS)) from pH sensitive poly(2-hydroxyethyl methacrylate/itaconic acid) (P(HEMA/IA)) hydrogels obtained by ...
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 ...
Low energy impact damage detection in laminar termoplastic composite materials by means of embedded optical fibers
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The possibility of applying optical fibers as sensors for investigation of real time low energy impact damage in laminar thermoplastic composite materials has been studied. For that purpose intensity based optical fibers ...
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 ...
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 ...
Hydrogen evolution reaction from EDTA solutions
(4th Conference of the Yugoslav Materials Research Society, 2002)
An attempt was made to investigate the mechanism and kinetics of hydrogen evolution reaction on zinc and platinum wire electrodes from solutions containing ethylene diamine tetraacetic acid (EDTA). EDTA is a tetra-basic ...
