Doped gamma-Bi2O3: synthesis of microcrystalline samples and crystal chemical analysis of structural data
(Walter de Gruyter Gmbh, Berlin, 2007)
A series of microcrystalline products containing the gamma-Bi2O3 phase doped with Co, Fe, Mn, Pb, Sb, Si, Ti, V and Zn has been prepared by solid state reaction. Based on the heating temperature and heating time, the ...
Adhesion and corrosion resistance of epoxy primers used in the automotive industry
(Taylor & Francis Ltd, Abingdon, 2007)
One of the most important factors in corrosion prevention by protective coatings is the loss of adhesion of the coating under environmental influence. Thus, adhesion strength is often used when characterizing protective ...
Synthesis and characterization of biodegradable aliphatic copolyesters with poly(tetramethylene oxide) soft segments
(Wiley, Hoboken, 2007)
A series of aliphatic poly(ether-ester)s based on flexible poly(tetramethylene oxide) (PTMO) and hard poly (butylene succinate) (PBS) segments were synthesized by the catalyzed two-step transesterification reaction of ...
Swelling and thermodynamic studies of temperature responsive 2-hydroxyethyl methacrylate/itaconic acid copolymeric hydrogels prepared via gamma radiation
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
The copolymeric hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) were synthesized by gamma radiation induced radical polymerization. Swelling and thermodynamic properties of PHEMA and copolymeric ...
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 ...
Swelling and drug release behavior of poly(2-hydroxyethyl methacrylate/itaconic acid) copolymeric hydrogels obtained by gamma irradiation
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
The new copolymeric hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) were prepared by gamma irradiation, in order to examine the potential use of these hydrogels in controlled drug release ...
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 ...
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 ...
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 ...
Investigation of the electrical behavior of some textile materials
(Elsevier, Amsterdam, 2007)
Some electrophysical properties of textile samples having different forms and raw material compositions were studied. For determining the electric resistance, a measuring device, based on the measurement of direct current ...
