Pore-Scale Modeling of Liquid Water Transport in Compressed Gas Diffusion Layer of Proton Exchange Membrane Fuel Cells Considering Fiber Anisotropy

open access: yesMembranes, 2023
Water management of the gas diffusion layer (GDL) is crucial to the performance of proton exchange membrane fuel cells (PEMFCs). Appropriate water management ensures efficient transport of reactive gases and maintains wetting of the proton exchange ...

Mars: Occurrence of Liquid Water [PDF]

open access: yesSymposium - International Astronomical Union, 1970
In the absence of juvenile liquid water, condensation and subsequent melting of ice are the only means of producing liquid water on the Martian surface. However, the evaporation rate is so high that the available heat sources cannot melt ice on Mars. Melting might occur only in concentrated solutions of strongly deliquescent salts.

Attosecond spectroscopy of liquid water [PDF]

open access: yesScience, 2020
Attosecond science in liquid phase Many physical properties of liquid water remain unresolved due to the very fast dynamics involved in the liquid phase. Using attosecond time-resolved photoelectron spectroscopy, Jordan et al.

Interparticle interactions between water molecules

open access: yesFrontiers in Physics, 2014
We determined many functional representations of interparticle interactions between water molecules, all of which reproduce the experimentally measured density-temperature relation at 1 bar with an accuracy better than obtained by previous models ...

Liquid-liquid phase transitions in supercooled water studied by computer simulations of various water models

open access: yes, 2005
Liquid-liquid and liquid-vapor coexistence regions of various water models were determined by MC simulations of isotherms of density fluctuation restricted systems and by Gibbs ensemble MC simulations. All studied water models show multiple liquid-liquid

Supercooled and glassy water: Metastable liquid(s), amorphous solid(s), and a no-man's land [PDF]

open access: yes, 2017
We review the recent research on supercooled and glassy water, focusing on the possible origins of its complex behavior. We stress the central role played by the strong directionality of the water-water interaction and by the competition between local

Balancing Local Order and Long-Ranged Interactions in the Molecular Theory of Liquid Water

open access: yes, 2007
A molecular theory of liquid water is identified and studied on the basis of computer simulation of the TIP3P model of liquid water. This theory would be exact for models of liquid water in which the intermolecular interactions vanish outside a finite ...

Reductive deposition of aluminum at a water-free ionic liquid/oil interface

open access: yesElectrochemistry Communications, 2023
The oil/water interface has been used as a reaction field for interfacial metal deposition via electron transfer between metal ions and reducing agents across the interface.
