Water forms spine of hydration around DNA group finds
2017/7/20
Water is the Earth’s most abundant natural resource, but it’s also something of a mystery due to its unique solvation characteristics – that is, how things dissolve in it.“It’s uniquely adapted to bio...
Phosphate Vibrations Probe Local Electric Fields and Hydration in Biomolecules
Phosphates Water Phospholipids Spectrophotometry, Infrared Electricity Models, Molecular
2016/5/25
The role of electric fields in important biological processes such as binding and catalysis has been studied almost exclusively by computational methods. Experimental measurements of the local electri...

mass transfer fluid flow hydration metamorphism Sanbagawa belt
2017/4/10
Trace element and Sr–Nd–Pb isotopic compositions of basic schists in the Cretaceous Sanbagawa metamorphic belt, a
typical regional metamorphic belt in the circum-Pacific orogeny, have been investigat...
Regularizing binding energy distributions and thermodynamics of hydration. Application to water modeled with classical and ab initio simulations
potential distribution theorem hydration free energy hybrid Monte Carlo vapor-liquid equilibrium
2011/8/5
Abstract: The high-energy tail of the distribution of solute-solvent interaction energies is poorly characterized for condensed systems, but this tail region is of principal interest in determining th...
Numerical simulations of an ocean/continent convergent system: influence of subduction geometry and mantle wedge hydration on crustal recycling
ocean/continent convergent system Numerical simulations subduction geometry and mantle wedge hydration
2011/9/5
The e ects of the hydration mechanism on continental crust recycling are analyzed through a 2D nite element thermo-mechanical model. Oceanic slab dehydration and consequent mantle wedge hydration are...
Range of ion specific effects in the hydration of ions
Hofmeister effect, potential distribution theorem, Monte Carlo, simulations
2011/8/29
Within the quasichemical approach, the hydration free energy of an ion is decomposed into a chemical term accounting for ion specific ion-water interactions within the coordination sphere and nonspeci...
Hydration and dehydration at the tropical tropopause
Hydration dehydration tropical tropopause
2009/12/31
High-resolution water measurements from three tropical airborne missions in Northern Australia, Southern Brazil and West Africa in different seasons are analysed to study the transport and transformat...
Could peridotite hydration reactions have provided a contributory driving force for Cenozoic uplift and accelerated subsidence along the margins of the North Atlantic and Labrador Sea?
peridotite hydration reactions contributory driving force Cenozoic uplift accelerated subsidence
2009/12/2
This study evaluates the hypothesis that peridotite hydration reactions (e.g.serpentinisation) at the landward termination of transform fracture zones provide a contributory driving force for coupled ...
Hydration increases the lifetime of HSO5 and enhances its ability to act as a nucleation precursor – a computational study
Hydration HSO5 nucleation precursor
2009/6/2
Recent experimental findings indicate that HSO5 radicals may play a key role in the nucleation of atmospheric SO2 oxidation products. HSO5 radicals are metastable intermediates formed in the SO2 oxida...

Crystalline Swelling Hydration Interlayer Cation Smectite
2011/12/6
Abstract: Smectites synthesized from experiments at 5.5 GPa and 1500癈 are of high quality, crystals are large at >10 祄, and the 2:1 layers may have a homogeneous charge distribution. Smectite was exch...
Effects of Iron Oxidation State and Organic Cations on Dioctahedral Smectite Hydration
