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 ...
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 ...
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 ...
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 ...
Performance of the CMS ECAL safety system for super modules SM0 and SM1
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2005)
A prototype of the safety system for the electromagnetic calorimeter (ECAL) of the CMS detector at LHC has been implemented and tested in Super Modules SM0 and SM1 during the ECAL test-beam campaign in summer 2003. The aim ...
Mathematical modeling of the hypothalamic-pituitary-adrenal system activity
(Mathematical Biosciences, 2005)
Mathematical modeling has proven to be valuable in understanding of the complex biological systems dynamics. In the present report we have developed an initial model of the hypothalamic-pitutary-adrenal system self-regulatory ...
Manifestations of dynamic strain ageing in 2090 Al-Li alloy
(Zeitschrift fur Metallkunde, 2005)
The manifestations of dynamic strain ageing in a commercial 2090 Al - Li alloy were investigated in a wide range of temperatures (-40 to 100 degrees C) and strain rates (4.16x10(-5) to 4.16x10(-3) s(-1)). Serrated yielding, ...
Density functional study of the insulating ground states in CaFeO3 and La1/3Sr2/3FeO3 compounds
(Physical Review B: Condensed Matter and Materials Physics, 2005)
The origin of the insulating ground states and the charge disproportionation in the two Fe-based perovskite oxides, viz., CaFeO3 and La1/3Sr2/3FeO3, are examined from ab initio electronic structure calculations based on ...
Some practical realizations of preset time count rate meters using optimized adaptive digital signal-processing solutions
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2005)
Two optimized adaptive digital signal processors were developed to implement the preset time count rate meters. The first processor improves stationary characteristics of the count rate meter by implementing the control ...
