Concentration and temperature stability of some structural and magnetic phases in the Hf-Fe system
(Materials Science Forum, 2003)
X-ray fluorescence and DTA-specific heat measurements were performed on several samples of the Hf-Fe phase system, at 50:50%, and 33:67% concentrations. In the first concentration range the possibility of an ordered compound ...
Far-infrared phonon spectroscopy of Cd1-xMnxS quantum dots
(Materials Science Forum, 2004)
Phonon spectra of Cd1-xMnxS (x =0; 0.01; 0.05; 0.1; 0.15; 0.3) quantum dots (dsimilar to4.5 nm) are investigated by far-infrared reflection in the spectral range 80 - 600 cm(-1) and temperature range 80-300 K. The Cd1-xMnxS ...
Local structures in Pb1-xMnxTe systems
(X-Ray Spectrometry, 2007)
The semimagnetic semiconductor Pb1-xMnxTe is a good representative of IV-VI narrow-gap semiconductors, the class of materials in which phenomena like variation of the band gap with composition, negative magnetoresistance, ...
The effect of gamma radiation on the properties of activated carbon cloth
(Journal of the Serbian Chemical Society, 2009)
Activated carbon cloth dressing is an appropriate wound healing material due to its biocompatibility and adsorption characteristics. The influence of gamma radiation as a sterilization process on the adsorption and mechanical ...
Surface Modification of Metallic Targets with Ultrashort Laser Pulses
(Acta Physica Polonica. Series A: General Physics, Physics of Condensed Matter, Optics and Quantum Electronics, Atomic and Molecular Physics, Applied Physics, 2009)
Interaction of pulsed femtosecond Ti:sapphire laser (160 fs), operating at high repetition rate (75 MHz) at 800 nm, with nickel-based superalloy Inconel 600 and tungsten-titanium (WTi) target was studied. The WTi target ...
Micro- and nanosecond laser TiN coating/steel modification: Morphology studies
(Russian Journal of Physical Chemistry A, 2009)
Morphology effects induced during interaction of mu s- (Transversely Excited Atmospheric (TEA) CO(2) laser) or ns- (HF laser) pulses with titanium nitride (TiN) coating, deposited on austenitic stainless steel AISI 316, ...
Moisture and gamma-ray irradiation effects on the mechanical properties of carbon fibre-reinforced plastics
(Journal of Microscopy, Oxford, 2008)
The effects of gamma-irradiation and moisture absorption on the mechanical properties of carbon fibres-epoxy resin composites were studied. The properties dominated by the matrix and fibre-matrix interface (interlaminar ...
Adsorption Characteristics of Activated Carbon Hollow Fibers
(Chemical Industry and Chemical Engineering Quarterly / CICEQ, 2009)
Carbon hollow fibers were prepared with regenerated cellulose or polysulfone hollow fibers by chemical activation using sodium phosphate dibasic followed by the carbonization process The activation process Increases the ...
Effect of Different Types of Stress on Adrenal Gland Parameters and Adrenal Hormones in the Blood Serum of Male Wistar Rats
(Archives of biological sciences, 2009)
In the present study, we examined gross changes in the mass of whole adrenal glands and that of the adrenal cortex and medulla in mature male Wistar rats subjected to three different stress types: acute, chronic, and ...
Antioxidant Enzymes Expression and Activity in Liver of Stressed Wistar Rat
(Russian Journal of Physical Chemistry A, 2009)
Altered activities of antioxidant defence system enzymes and the levels of free radicals scavengers have been found to correlate with various physiological or pathological conditions, including stress. The aim of this study ...
