Study of Thermal Phase Transitions in Iota Carrageenan Gels via Fluorescence Technique
Authors:
Publisher and Date:(Wiley-Blackwell, 2011)The effect of carrageenan concentration on thermal phase transitions of the iota carrageenan gels was investigated by using fluorescence technique. During heating and cooling processes scattered light I(sc) and fluorescence intensity I(p) were monitored against temperature to investigate phase transitions. Transition temperatures from the derivative of the transition paths were determined. Two regions were observed during the heating and cooling processes. At the first step of the heating dimers ...

Thermal Phase Transitions of Agarose in Various Compositions: A Fluorescence Study
Authors:
Publisher and Date:(Springer/Plenum Publishers, 2011)The effect of agarose content on thermal phase transitions of the agarose gels was investigated by using Steady State Fluorescence (SSF) method. Scattered light I(sc) and fluorescence intensity I(fl) were monitored against temperature during heating and cooling processes to investigate phase transitions. Two regions were observed during the heating and cooling processes. At the high temperature region double helix to coil (h-c) transition took place. However during the cooling process coil to ...
