Graphene modified fluorinated cation-exchange membranes for proton exchange membrane water electrolysis [PDF]
International Journal of Hydrogen Energy, 2019 Abstract One of major current technical challenges in proton exchange membrane water electrolysis (PEMWE) is the limited proton conductivity. Nowadays, graphene is considered one of the most promising candidates for improving the ionic transport properties, isotopic selectivity and proton conductivity throughout the unique two-dimensional structure ...

The Role of Ion Exchange Membranes in Membrane Capacitive Deionisation
Membranes, 2017 Ion-exchange membranes (IEMs) are unique in combining the electrochemical properties of ion exchange resins and the permeability of a membrane. They are being used widely to treat industrial effluents, and in seawater and brackish water desalination ...

Integration of monopolar and bipolar electrodialysis for valorization of seawater reverse osmosis desalination brines: Production of strong acid and base [PDF]
, 2016 Water scarcity in the Mediterranean basin has been solved by using seawater desalination reverse osmosis technology (SWD-RO). This technology produces brine which is discharged back into the sea resulting in an environmental impact on marine ecosystems ...

Correlation between macroscopic sugar transfer and nanoscale interactions in cation exchange membranes [PDF]
, 2015 Previous experimental work has shown that the transfer of organic solutes through ion-exchange membranes depends on the membrane counter-ion and that this dependence is probably linked to the interactions taking place at the nanoscale inside the membrane

Current-voltage curve of a bipolar membrane at high current density [PDF]
, 1996 The potential drop across a bipolar membrane was measured as a function of the applied current density. As a result, an inflection point was observed in the obtained current-voltage curve at high current density.

Electrostatically localized proton bioenergetics: better understanding membrane potential
Heliyon, 2019 In Mitchell's chemiosmotic theory, membrane potential Δψ was given as the electric potential difference across the membrane. However, its physical origin for membrane potential Δψ was not well explained.
