Optical properties of Hg1-xMnxTe1-ySey
(Infrared Physics and Technology, 2005)
Far-infrared reflectivity spectra of Hg1-xMnxTe1-ySey (0.01 and LE; x and LE; 0.14, 0.01 and LE; y and LE; 0.1) single crystals were measured in the 80-420cm(-1) range at room temperature. The analysis of the far-infrared ...
Transition from amorphous to crystalline beta phase in co-sputtered FeSi2 films as a function of temperature
(Journal of Applied Physics, 2005)
A study of the stability of amorphous FeSi2 films and their transition to a crystalline phase as a function of deposition or annealing temperature is presented. Stoichiometric FeSi2 films, 300-400 nm thick, were deposited ...
Thermodynamic limit for the Ising model on the Cayley tree
(Physica A: Statistical Mechanics and Its Applications, 2005)
While the Ising model on the Cayley tree has no spontaneous magnetization at nonzero temperatures in the thermodynamic limit, we show that finite systems of astronomical sizes remain magnetically ordered in a wide temperature ...
Hyperbolic propagation of a thermal signal in an inhomogeneous medium
(Materials Science Forum, 2005)
A numerical procedure for the calculation of space distribution of the thermal field in thermally inhomogeneous solids with thermal memory induced by a harmonically modulated surface heat source is presented. The procedure ...
Kobayashi-Kondo-Maskawa-t Hooft interaction in pentaquarks
(Physical Review D, 2005)
We review critically the predictions of pentaquarks in the quark model, in particular, those based on the flavor-spin-dependent (Glozman-Riska) hyperfine interaction and the color-spin (one-gluon-exchange Fermi-Breit) one. ...
Infrared study of laser synthesized anatase TiO2 nanopowders
(Journal of Physics. D: Applied Physics, 2005)
Nanosized titanium dioxide (TiO2) is synthesized by laser-induced pyrolysis using titanium isopropoxide as a liquid precursor. The specific surface area of as-produced nanopowders measured by the Brunauer-Emmett-Teller ...
Spectrophotometric and 27-Al NMR characterization of aluminum(III) complexes with L-histidine
(Spectroscopy Letters, 2005)
The complex formation between L-histidine (HHis) and aluminum(III) ion in water solutions was studied by UV spectrophotometric and 27-Al NMR measurements at 298 K. UV spectra were measured on solutions in which the total ...
Structural, spectroscopic and computational studies of the HgL2Cl2 complex (L=3,5-dimethyl-1-thiocarboxamide pyrazole) and the crystal structure of L
(New Journal of Chemistry, 2005)
In the present paper we report the synthesis as well as the structural and vibrational characterisation of the HgL2Cl2 complex ( L = 3,5-dimethyl-1-thiocarboxamide). The crystal and molecular structures of both L and the ...
Comparison of hydroxyapatite sorption properties towards cadmium, lead, zinc and strontium ions
(Materials Science Forum, 2005)
Apatites are well known matrix for heavy metal immobilization and remediation of ground water and contaminated soils. In this work, capacities of different synthetic hydroxyapatite (HAP) samples for Pb, Cd, Sr and Zn ...
A way to determine radiation-induced loss in fiber-optic digital communication link
(Optical Fiber Technology, 2005)
The gamma radiation (Co-60) effect to the PCS fiber-optic in real digital communication link was investigated. The radiation-induced loss were determined by new method, using discrete data obtained by the sampling oscilloscope ...
