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 ...
Synthesis of functionally graded bioactive glass-apatite multistructures on Ti substrates by pulsed laser deposition
(Elsevier Science Bv, Amsterdam, 2007)
Functionally graded glass-apatite multistructures were synthesized by pulsed laser deposition on Ti substrates. We used sintered targets of hydroxyapatite Ca-10(PO4)(6)(OH)(2), or bioglasses in the system SiO2-Na2O-K2O-C ...
Ca-alginate hydrogel mechanical transformations - The influence on yeast cell growth dynamics
(Elsevier, Amsterdam, 2007)
A mathematical model was formulated to describe yeast cell growth within the Ca-alginate microbead during air-lift bioreactor cultivation. Model development was based on experimentally obtained data for the intra-bead cell ...
Thermal, oxidative and radiation stability of polyimides. Part IV: Polyimides based on N-[4-benzoyl-2-(2,5-dioxo-2,5-dihydro-pyrrol-1-yl)-phenyl]-acetamide and different diamines
(Elsevier Sci Ltd, Oxford, 2007)
Polyimide resins were obtained from the reaction between N-[4-benzoyl-2-(2,5-dioxo-2,5-dihydro-pyrrol-1-yl)-phenyl]-acetamide and the following compounds with terminal amino groups: urea, 4-[(4-aminophenyl)sulfonyl] aniline, ...
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. ...
Volumetric properties of the binary methanol plus chloroform and ternary methanol plus chloroform plus benzene mixtures at (288.15, 293.15, 298.15, 303.15, 308.15, and 313.15) K
(Amer Chemical Soc, Washington, 2007)
Densities rho of the ternary system of methanol + chloroform + benzene and binary mixture of methanol + chloroform have been measured at six temperatures (288.15, 293.15, 298.15, 303.15, 308.15, and 313.15) K and atmospheric ...
Direct hemp cellulose dissolution in N-Methylmorpoline-N-Oxide
(Taylor & Francis Inc, Philadelphia, 2007)
The increased production of bast fibres (especially hemp fibres) brought about an increase in the amount of waste, namely shive (hemp stalks) and short fibres. This waste presents a potential significant source of high ...
Study of the kinetics and the influence of Bi-irr, on formic acid oxidation at Pt2RU3/C
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Electrochemical oxidation of HCOOH in H2SO4 and HCIO4 solutions was examined on thin film Pt2RU3/C electrode. XRD pattern revealed that Pt2RU3 alloy consisted of the solid solution of Ru in Pt and the small amount of Ru ...
Preparation of heterogeneous catalyst for biodlesel synthesis
(2007 AIChE Annual Meeting, 2007)
Certain disadvantages of conventional processes of biodiesel, i.e. fatty acid methyl esters (FAME) synthesis could be avoided by applying new technologies which are based on using heterogeneous catalyst. In this study a ...
Oxygen transport in tissue engineering systems: Cartilage and myocardium
(Fluid Dynamics and Materials Processing, 2007)
Efficient transport of oxygen is one of the main requirements in tissue engineering systems in order to avoid cell death in the inner tissue regions and support uniform tissue regeneration. In this paper, we review approaches ...
