Dynamics of confined water molecules [PDF]
We present femtosecond midinfrared pump–probe measurements of the molecular motion and energy-transfer dynamics of a water molecule that is enclosed by acetone molecules. These confined water molecules show hydrogen-bond and orientational dynamics that are much slower than in bulk liquid water.

THz Dynamics of Nanoconfined Water by Ultrafast Optical Spectroscopy
We investigated the vibrational dynamics and the structural relaxation of water nanoconfined in porous silica samples with pore size of 4 nm at different levels of hydration and temperature.

Molecular Basis of Water Activity in Glycerol–Water Mixtures
Water activity (Aw) is a reliable indication of the microbial growth, enzymatic activity, preservation, and quality of foods. However, a molecular basis of Aw is still under debate in multiple related disciplines.

Snow water equivalent dynamics in the Yesil water management basin
The article presents the snow water equivalent (SWE) dynamics in the Yesil Water Management Basin during 1971-2019. The main research purpose was to study the SWE dynamics, since – being a powerful climate-forming factor – snow cover plays an important ...

Sustainable land management requires that water and matter (nutrients and base cations) are efficiently recycled within ecosystems so that irreversible losses of matter from topsoils are minimised. Matter losses are connected to water flow.

Curvature Dependence of Hydrophobic Hydration Dynamics
We investigate the curvature-dependence of water dynamics in the vicinity of hydrophobic spherical solutes using molecular dynamics simulations. For both, the lateral and perpendicular diffusivity as well as for H-bond kinetics of water in the first ...

Karst water as the vital water supply source is generally suffered from NO3– contamination in intensive agricultural areas worldwide. Identifying NO3– sources and transformations is the key for understanding nitrogen pathways, and also for effectively ...

Carbonate minerals are the largest carbon (C) reservoir on earth. Quantitative assessment of carbonate weathering and CO2 sink flux caused by anthropogenic acids in karst wetland regions is imperative to improve understanding of the hydrogeochemical ...

Water–Peptide Dynamics during Conformational Transitions [PDF]
Transitions between metastable conformations of a dipeptide are investigated using classical molecular dynamics simulation with explicit water molecules. The distribution of the surrounding water at different moments before the transitions and the dynamical correlations of water with the peptide's configurational motions indicate that the water ...

Solvent Induced Proton Hopping at a Water-Oxide Interface [PDF]
Despite widespread interest, a detailed understanding of the dynamics of proton transfer at interfaces is lacking. Here we use ab initio molecular dynamics to unravel the connection between interfacial water structure and proton transfer for the widely ...
