Liquid water contains the building blocks of diverse ice phases
Nature Communications, 2020 Molecular understanding of water is challenging due to the structural complexity of liquid water and the large number of ice phases. Here the authors use a machine-learning potential trained on liquid water to demonstrate the structural similarity of ...

Remarks on Life Feasibility on the Red Planet
MicroorganismsThe current strong interest in the exploration of Mars leads to the question of the actual possibility of the presence or possible past or future development of life on the planet. Several clues suggest that liquid water could be stably present under the

Two exchange-correlation functionals compared for first-principles liquid water [PDF]
, 2005 The first-principles description of liquid water using ab initio molecular dynamics (AIMD) based on Density Functional theory (DFT) has recently been found to require long equilibration times, giving too low diffusivities and a clear over-structuring of ...

Influence of disordered porous media in the anomalous properties of a simple water model
, 2015 The thermodynamic, dynamic and structural behavior of a water-like system confined in a matrix is analyzed for increasing confining geometries. The liquid is modeled by a two dimensional associating lattice gas model that exhibits density and diffusion ...
