A model of AlN layer formation during ion nitriding of Al
(Springer-Verlag, 2004-11)
A diffusion model of AlN layer formation by ion nitriding of Al is proposed based on the analysis of atomic transport during the process. This model is reduced to the following. Implantation of N ions to the surface of the ...
Cation effects on phase transition of kappa-iota-carrageenan hybrids: a photon transmission study
(Taylor & Francis Group, 2007)
Phase transitions of kappa-iota-carrageenan hybrid in various types of salts were studied using photon transmission technique: NaCl, KCI, MgCl2, CaCl2 and KCl+CaCl2 were chosen as the salt solutions for the carrageenan ...
Drying of PAAm hydrogels at various temperatures: A fluorescence study
(Taylor & Francis Group, 2007-05)
The steady-state fluorescence (SSF) technique was employed for studying the drying of polyacrylamide (PAAm) hydrogels. Disc-shaped hydrogels were prepared by free-radical crosslinking copolymerization of acrylamide (AAm) ...
Temperature effect on drying and swelling of kappa carrageenan gels: A steady state fluorescence study
(Wiley-V C H Verlag GMBH, 2008)
A novel technique based on in situ steady state fluorescence (SSF) measurements is introduced for studying drying and swelling Of kappa(-) carrageenan (kappa carrageenan) gels at various temperatures. kappa(-) carrageenan ...
Interpretation of the glass transition temperature from the point of view of molecular mobility
(Springer, 2005)
Glass transition has been one of the biggest challenges in condensed matter physics during the last century: in spite of significant progress we still cannot explain the sudden solidification of undercooled liquids on the ...
Theoretical calculation of the kinetic coefficient of normal crystal growth
(Trans Tech Publications Ltd, 2004)
An expression for the velocity u of migration of a diffuse simple crystal-melt interface has been derived on the basis of the theory of atomic mobility in supercooled liquids: u = K-0 (T / T-m) DeltaT, where DeltaT = T-m ...
Breakdown of the Stokes-Einstein relation in supercooled liquids
(Trans Tech Publications Ltd, 2004)
Breakdown of the Einstein-Stokes relation in undercooled liquids is one of the unsolved problems in the theory of liquids. The self-diffusion coefficient follows the temperature dependence of the Einstein-Stokes equation ...
P-T phase diagram for NH?F
(Editions Scientifiques Medicales Elsevier, 2002-04)
In this study we obtain a P-T phase diagram of NH4F using the mean-field theory. We fit our calculated phase line equations to the experimental P-T phase diagram. By choosing appropriately the coefficients in the free-energy ...
Molecular recognition during sol-gel and gel-sol transition of kappa-iota carrageenan mixtures
(Taylor & Francis ltd, 2005-12)
Sol-gel and gel-sol phase transitions of kappa-iota (kappa-iota) carrageenan mixtures in two types of salts were studied using photon transmission technique. Here, KCl and CaCl2 were chosen as the proper salts for the ...
T-P phase diagram of ammonia solid phases I, II and III
(Elsevier Science, 2002-01-02)
In this study, using the mean field theory, we obtain temperature versus pressure phase diagram for the liquid and solid phases I, II, and III of ammonia. We fit, our phase line equations to the experimentally observed ...
