Dynamic scaling and slowing down in chemical reactions of the critical triethylamine-water system
Article Abstract:
Several special ultrasonic attenuation measurements are carried out to determine the Bhattacharjee-Ferrell scaling function, as well as to observe the phenomenon of dynamic scaling and slowing in chemical reactions of the triethylamine-water system. The analysis reveals that water play a very essential role in the unimolecular isomerization, which comes about as a result of an extensive arrangement of the hydration shells associated with the entire isomerization process.

Microsecond to subnanosecond molecular relaxation dynamics of the interaction of Ca2+ with some carbohydrates in aqueous solution
Article Abstract:
Research was conducted to examine the microsecond to subnanosecond molecular relaxation dynamics of the interaction of Ca2+ with some carbohydrates in aqueous solution. Solutions of methyl-beta-D-arabinopyranoside and of 1,6-anhydro-beta-D-glucopyranoside, both with and without added Ca2+ and Ba2+ ions were studied using ultrasonic absorption spectra in the frequency range 1-500 MHz. Results provide strong evidence of cation-carbohydrate complex formation.

Molecular dynamics and kinetics of monosaccharides in solution. A broadband ultrasonic relaxation study
Article Abstract:
It has been possible to measure between 100 kHz and 2 GHz ultrasonic absorption spectra for aqueous solutions of D-mannose, D-galactose, D-ribose, D-glucose, D-arabinose, D-xylose and D-lyxose. This research identified a high frequency relaxation which appears to be the result of local fluctuations in the carbohydrate concentration.
