Modification of carbon cloth by interaction with pulsed TEA CO2 laser
(Materials Science Forum, 2004)
The interaction of a Transversely Excited Atmospheric (TEA) CO2 laser (pulse duration less than 2 mus) with carbon and activated carbon cloth was investigated. The investigations have shown that carbon cloth had been ...
Thermal diffusivity of cold sintered Co
(Materials Science Forum, 2004)
Cold sintering of cobalt powder (up to 1.2 GPa) was accompanied by measurements of density and thermal diffusivity. Dependence of density change upon pressing pressure is derived. Thermal diffusivity of the material was ...
The influence of the solid/liquid ratio on the point of zero charge of alumina
(Materials Science Forum, 2004)
The point of zero charge (pH(pzc)) of three samples of commercial aluminum oxide in aqueous KNO3 (10(-3) - 10(-1) mol/dm(3)) solution was investigated using batch equilibration, mass titration and acid-base titration ...
Thermostability and surface morphology of nano- and micro-filled NBR/CSM and CR/CSM rubber blends
(Journal of the Serbian Chemical Society, 2004)
Acrylonitrile-butadiene rubber (NBR), polychloroprene rubber (CR). chlorosulphonated polyethylene rubber (CSM) and their blends were cross-linked with sulphur, ethylene-thiourea. magnesium oxide or their combination. The ...
X-ray photoelectron study of calcium cerium titanate ceramics
(Russian Journal of Inorganic Chemistry, 2004)
The elemental and ionic quantitative compositions and oxidation states of elements in the ceramics CaCe0.9Ti2O6.8 (I) and CaCeTi2O7 (II)-matrices for long-term storage of long-lived radionuclides constituting hi-h-level ...
Development of solidification techniques for radioactive sludge produced by a research reactor
(Progress in Nuclear Energy, 2004)
In the last forty years in the Vinca Institute, as a result of the operation of two research reactors, named RA and RB, and as a result of the application of radionuclides in medicine, industry and agriculture, radioactive ...
Synthesis of in situ reinforced silicon nitride composites
(Journal of the Serbian Chemical Society, 2004)
The objective of this work was to investigate the effect of two different sintering additives (CeO2 and Y2O3 + Al2O3), sintering time and amount of beta-Si3N4 seeds on the densification. mechanical properties and microstructure ...
Antibodies reactive with C-terminus of the second conserved region of HIV-1gp120 as possible prognostic marker and therapeutic agent for HIV disease
(Journal of Clinical Virology, 2004)
It has been reported that antibodies reactive with peptide RSANFTDNAKTIIVQLNQSVEIN (peptide NTM) derived from the C-terminus of the second conserved domain of HIV-1 envelope glycoprotein gp120 could represent an important ...
Cobalt(II) chloride complex formation in acetamide-calcium nitrate tetrahydrate melts
(Journal of Solution Chemistry, 2004)
The absorption spectra of Co(II) chloride complexes, containing variable concentrations of chloride ligand, in a molten mixture of 80 mol% acetamide-20 mol% calcium nitrate tetrahydrate, were studied at 313, 333, 353, and ...
Age-related changes in radiation-induced micronuclei among healthy adults
(Brazilian Journal of Medical and Biological Research, 2004)
The aim of the present study was to establish the extent of in vitro radioresponse of lymphocytes among 62 healthy adults of both genders and to estimate the distribution of baseline micronuclei and radiosensitivity among ...
