The influence of cations on the dipole moments of neighboring polar molecules
Imre Bakó, Dániel Csókás, István Mayer +2
It is shown that the dipole moment of polar (water, methanol, formamide, acetone and acetonitrile) molecules in the neighborhood of a cation is increased primarily by polarization…
Molecular aggregation in liquid water: Laplace spectra and spectral clustering of H-bonded network
Imre Bakó, Dániel Csókás, Szilvia Pothoczki
Application of the spectral clustering method based on the analyses of the Laplace matrix is an acceptable indicator of the global properties of H-bonded network. The first peak of…
Hydrogen bonding and percolation in propan-2-ol -- water liquid mixtures: X-ray diffraction experiments and computer simulations
Szilvia Pothoczki, Ildikó Pethes, László Pusztai +5
Synchrotron X-ray diffraction measurements have been conducted on aqueous mixtures of propan-2-ol (a.k.a. isopropanol, or 2-propanol), for alcohol contents between 10 and 90 molar…
Temperature dependent structure and dynamics of isopropanol-water liquid mixtures at low alcohol content
Szilvia Pothoczki, László Pusztai, Imre Bakó
Series of molecular dynamics simulations for 2-propanol-water mixtures, as a function of temperature (between freezing and room temperature) and composition (xip= 0, 0.5, 0.1 and 0…
Temperature dependent network stability in simple alcohols and pure water: the evolution of Laplace spectra
I. Bakó, I. Pethes, Sz. Pothoczki +1
A number of computer-generated models of water, methanol and ethanol are considered at room temperature and ambient pressure, and also as a function of temperature (for water and e…
Temperature dependent dynamics in water-ethanol liquid mixtures
Szilvia Pothoczki, László Pusztai, Imre Bakó
Temperature dependent hydrogen bond energetics and dynamical features, such as the diffusion coefficient and reorientational times, have been determined for ethanol-water mixtures…
