Journal ArticleDOI
The Johari-Goldstein beta-relaxation of water.
TL;DR: The similarities in properties lead us to conclude that the nu-processes in water mixtures are the Johari-Goldstein (JG) secondary relaxations of water.
Journal ArticleDOI
Glass transitions in aqueous solutions of protein (bovine serum albumin).

TL;DR: Broadband dielectric measurements of BSA-water mixtures at various BSA concentrations over a wide frequency range of thirteen decades indicate in hydrated BSA or other proteins that the secondary relaxation of water and the conformation fluctuations of the protein in the hydration shell are inseparable or symbiotic processes.
Journal ArticleDOI
Dynamics of Water in a Polymer Matrix Studied by a Microwave Dielectric Measurement
TL;DR: In this article, the distribution of the relaxation time is interpreted by the variation of the water structure, which suggests that water structures in the mixtures of the former group are more uniform and stable than that in the mixture of the latter group.
Journal ArticleDOI
Microwave dielectric study on bound water of globule proteins in aqueous solution
TL;DR: A dielectric relaxation peak due to bound water of globule proteins in aqueous solution was observed at first by the use of a time domain reflectometry as discussed by the authors, which was suggested that this peak is caused by orientation of bound water molecules on the protein surface.
Journal ArticleDOI
Dielectric Relaxation Time and Relaxation Time Distribution of Alcohol−Water Mixtures
TL;DR: In this article, the authors measured complex permittivity in the frequency range from 10 MHz to 20 GHz at 25 °C for water mixtures of 22 aliphatic alcohols, and found a strong correlation between the broadness of dielectric loss and the number of carbon atoms in the alcohol molecule.
