Effect of Basicity on the Hydrolysis of the Bi(III) Aqua Ion in Solution: An Ab Initio Molecular Dynamics Study
(American Chemical Society, 2018-02-22)
Hydrolysis of the Bi(III) aqua ion under a range of solution conditions has been studied by means of ab initio molecular dynamics simulations. While the Bi(III) aqua ion is stable in pure water, there is an increasing ...

Solving the Hydration Structure of the Heaviest Actinide Aqua IonKnown: The Californium(III) Case
(Wiley-Blackwell, 2010)
Wish they all could be californium: X-ray absorption spectroscopy (black points) and Monte Carlo simulations (blue line) of Cf" in aqueous solutions have been combined to determine the ligand distance and coordination ...

Microsolvatación de cationes en disolución. Desarrollo del modelo de ion hidratado intercambiable y su aplicación a la química de cationes radiactivos
(2010-12-20)
Aqua ions, of general formula [M(H2O)n ] m+, are the most common structures adopted by metal cations, Mm+, when chemical conditions inhibit the formation of hydrolyzed and polymerized derivatives. 1 The implicit net charge, ...

Theoretical study on the hydrophobic and hydrophilic hydration on large solutes: The case of phthalocyanines in water
(American Institute of Physics Publising LLC, 2015)
A theoretical study on the hydration phenomena of three representative Phthalocyanines (Pcs): the metal-free, H2Pc, and the metal-containing, Cu-phthalocyanine, CuPc, and its soluble sulphonated derivative, [CuPc(SO3)4]4−, ...

Impact of the number of fitted Debye-Waller factors on EXAFS fitting
(IOP Publishing, 2013)
EXAFS fit applied to asymmetric systems may imply the fit of parameters for many scattering paths. We illustrate on some examples how fitting too many independent DWs may lead to incorrect distances and mask some structural ...

Modeling the interactions of phthalocyanines in water: From the Cu(II)-tetrasulphonate to the metal-free phthalocyanine
(American Institute of Physics (AIP), 2011)
A quantum and statistical study on the effects of the ions Cu2+ and SO3− in the solvent structure around the metal-free phthalocyanine (H2Pc) is presented. We developed an ab initio interaction potential for the system ...

Hydration and Diffusion Mechanism of Uranyl in Montmorillonite Clay: Molecular Dynamics Using an Ab Initio Potential
(ACS, 2017-10-20)
Permanent geological repositories lined with bentonite, a montmorillonite-containing clay, is one of the options considered for the storage of high-level radioactive waste. If the fuel rods were dissolved by a water ...
