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 ... -
The liquid–glass transition – is it a fourth order phase transition?
(Elsevier Science, 2005-09-01)The liquid-glass transition is analyzed using a theory of Brownian motion in liquids recently developed by the author. It is shown that if a liquid could be cooled in quasi-static process and still avoids crystallization ... -
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 ... -
Monovalent and divalent cation effects on phase transitions of iota-carrageenan
(Sage Publications Ltd, 2007-01)Phase transitions Of L-carrageenan in a variety of monovalent (Li, Na, K) and divalent (Mg, Ca, Sr) cation solutions were studied during heating and cooling by using photon transmission technique. Photon transmission ... -
Photon transmission study on conformational ordering of iota-carrageenan in CaCl2 solution
(Taylor & Francis Inc, 2005-06)Coil-to-double helix (c-h) and double helix-to-dimer (h-d) phase transitions of iota-carrageenan in CaCl2 solution upon cooling were studied using photon transmission technique. Photon transmission intensity, I-iota r was ... -
Small molecule diffusion into swelling Iota-Carrageenan gels: A fluorescence study
(Taylor & Francis Group, 2007-04)Small molecule diffusion into Iota-Carrageenan gel was studied by using steady-state fluorescence (SSF) technique. Pyranine, dissolved in water was used as fluorescence probe. Fluorescence emission intensity, I-p, and ... -
Small molecule sorption and desorption in and out of iota-carrageenan gels
(Taylor & Francis Group, 2007-08)Small molecule sorption and desorption in and out of Iota-Carrageenan was studied by using steady-state fluorescence (SSF) technique. Pyranine dissolved in water used as fluorescence probe. Fluorescence emission intensity, ... -
Study on critical behaviour in N-isopropyl acrylamide gels by using fluorescence technique
(Taylor & Francis Group, 2006-11)The steady state fluorescence (SSF) technique was used to study the sol-gel transition for the solution free radical crosslinking copolymerization of N-isopropyl acrylamide (NIPA), with N,N'-methylenebis (acrylamide) (BIS) ... -
Swelling of iota-carrageenan gels prepared with various CaCl2 content: A fluorescence study
(European Polymer Federation, 2008-01-05)Iota carrageenan gels prepared with various CaCl2 content were completely dried and then swelled in water vapor. Steady-state fluorescence ( SSF) technique was used to monitor the swelling process of each iota carrageenan ...
