Dynamics of Bound and Free Water in an Aqueous Micellar Solution : Analysis of the Lifetime and Vibrational Frequencies of Hydrogen Bonds at a Complex Interface [PDF]

open access: yes, 2003
In order to understand the nature and dynamics of interfacial water molecules on the surface of complex systems, large scale molecular dynamics simulations of an aqueous micelle of cesium perfluorooctanoate surfactant molecules have been carried out. The

Thermal tuning of protein hydration in a hyperthermophilic enzyme

open access: yesFrontiers in Molecular Biosciences, 2022
Water at the protein surface is an active biological molecule that plays a critical role in many functional processes. Using NMR-restrained MD simulations, we here addressed how protein hydration is tuned at high biological temperatures by analysing ...

Correlated dynamics of water and amphiphilic molecules in thin Newton black films [PDF]

open access: yes, 2010
The dynamical properties of amphiphilics in Newton black films, as well as those of the water confined between the two charged hydrophilic surfaces, have been calculated via a series of molecular dynamic calculations in several films with different water

Dynamics of Water and Other Molecular Liquids Confined Within Voids and on Surface of Lignin Aggregates in Aging Bio Crude Oils

open access: yesFrontiers in Chemistry, 2021
Neutron scattering methods were employed to study the microscopic structure and dynamics of Bio Crude Oils (BCOs) and their lignin fractions. The structure of the carbonaceous aggregates was investigated using Small Angle Neutron Scattering to reveal a ...

A simplified model to predict diurnal water temperature dynamics in a shallow tropical water pool [PDF]

open access: yes, 2008
Water temperature is a critical regulator in the growth and development of malaria mosquito immatures, as they are poikilothermic. Measuring or estimating the diurnal temperature ranges to which these immatures are exposed is of the utmost importance, as

Low Field NMR Studies of Wheat Bread Enriched with Potato Juice During Staling

open access: yesOpen Agriculture, 2019
Potato juice is a by-product in the production of starch from potato tubers. However, published studies indicate that it is a source of bioactive compounds with antioxidant and anti-inflammatory effects. The use of health-promoting additives may, however,

Insights into Hydration Dynamics and Cooperative Interactions in Glycerol-Water Mixtures by Terahertz Dielectric Spectroscopy. [PDF]

open access: yes, 2019
We report relaxation dynamics of glycerol-water mixtures as probed by megahertz-to-terahertz dielectric spectroscopy in a frequency range from 50 MHz to 0.5 THz at room temperature.

Active-site solvent replenishment observed during human carbonic anhydrase II catalysis

open access: yesIUCrJ, 2018
Human carbonic anhydrase II (hCA II) is a zinc metalloenzyme that catalyzes the reversible hydration/dehydration of CO2/HCO3−. Although hCA II has been extensively studied to investigate the proton-transfer process that occurs in the active site, its ...

Microscopic mechanism of protein cryopreservation in an aqueous solution with trehalose [PDF]

open access: yes, 2013
In order to investigate the cryoprotective mechanism of trehalose on proteins, we use molecular dynamics computer simulations to study the microscopic dynamics of water upon cooling in an aqueous solution of lysozyme and trehalose.

Soil Water Dynamics.

open access: yesVadose Zone Journal, 2004
ARTHUR W. WARRICK. Oxford University Press, New York, NY 10016. 2003. Hardcover. 416 pp. $85.00. ISBN 0-19-512605-X. As implied by the title, Dr. Warrick's book focuses on the transport of water in soils, rather than also addressing the many broader topics of soil and environmental physics ...
