Comment on "gel-fluid transition in dilute versus concentrated DMPG aqueous dispersions"

Article Abstract:

The changes in the thermal behavior of dimyristoyl phosphatidyl glycerol (DMPG) caused by lipid dilution are discussed. It was observed that below a certain DMPG concentration the intermediate phase vanished, being replaced by a much narrower transition, centered at a single Tm value, which increased from 27 degree Celsius to 42 degree Celsius as the lipid concentration was decreased from 0.1 to 0.01 mM DMPG.

CO rebinding kinetics to myoglobin- and R-state-hemoglobin-doped silica gels in the presence of glycerol

Article Abstract:

The CO rebinding kinetics after photo dissociation of horse heart myoglobin (Mb) and human R-state hemoglobin (Hb) encapsulated in wet silica gels are characterized in the presence of various concentrations of glycerol. Rate constants have been modeled using a modified Kramers equation, which indicated that the gel exerts an internal friction on the elementary rate constants.

Changes of the primary and secondary relaxation of sorbitol in mixtures with glycerol

Article Abstract:

The dielectric relaxation experimental data on the alpha and Johari-Goldstein beta-relaxation dynamics of sorbitol in the neat state and in mixtures with glycerol published by Duvvuri and Richert is described. Fair agreements are found between the predictions of the model and data of neat sorbitol and mixtures of orbital with glycerol.
