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 ...
Bioactive glass and hydroxyapatite thin films obtained by pulsed laser deposition
(Elsevier, Amsterdam, 2007)
Bioactive glass (BG), calcium hydroxyapatite (HA), and ZrO2 doped HA thin films were grown by pulsed laser deposition on Ti substrates. An UV KrF* (lambda = 248 nm, tau gt = 7 ns) excimer laser was used for the multi-pulse ...
Multiphysics modeling of electric-swing adsorption system with in-vessel condensation
(Springer, Dordrecht, 2007)
Mathematical modeling of an Electric-Swing Adsorption (ESA) system (adsorption cycle with electrothermal desorption step, performed by direct heating of the adsorbent particles by passing electric current through them), ...
Preliminary characterization of lactic acid bacteria isolated from Zlatar cheese
(Wiley, Hoboken, 2007)
Aims: Isolation, characterization and identification of lactic acid bacteria (LAB) from artisanal Zlatar cheese during the ripening process and selection of strains with good technological characteristics. Methods and ...
Optimization of the scheduler for the non-blocking high-capacity router
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2007)
The sequential greedy scheduling (SGS) is a scalable maximal matching algorithm that provides non-blocking in an Internet router with input buffers and a cross-bar. In this paper, we will present the FPGA design of the SGS ...
Physical and mathematical models of an inert macroelectrode modified with active hemispherical microelectrodes
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
The physical model of an inert electrode partially activated with hemispherical microelectrodes was formed by the deposition of silver grains on a graphite substrate. It is shown that the process on the microelectrodes can ...
Determination of Pb and Cd in water by potentiometric stripping analysis (PSA)
(Elsevier B.V., 2007)
The aim of this work was to determine the content of cadmium(II) and lead(II) in drinking spring and well waters from rural part of south Serbia, as in a tap water. We have examined the Jablanica river water as well, which ...
A kinetic study of the thermal degradation of 3-methylaminopropylamine inside AlPO4-21
(Springer, Dordrecht, 2007)
Kinetics of the thermal decomposition of 3-methylaminopropylamine which was used as a structure-directing agent in the synthesis of AlPO4-21 has been studied under isothermal and non-isothermal conditions. The decomposition ...
STM image visualization of Si(111) 7 x 7 surface (graphic simulation and implementation)
(Elsevier Science Bv, Amsterdam, 2007)
The possibilities of graphic STM image simulation of a clean Si(1 1 1) 7 x 7 surface at atomic level are indicated. The presented procedure takes into account various types of deformation on the surface near the Fermi level ...
Analysis of the properties of a Cu-Al2-O3 sintered system based on ultra fine and nanocomposite powders
(International Institute for the Science of Sintering, Beograd, 2007)
In this paper synthesis of a composite based on Cu-Al2O3 by a thermo-chemical method is shown along with a comparative analysis of the properties of the obtained nanocomposite sintered samples, which are characterized by ...
