Mixed-conducting LSC/CGO and Ag/CGO composites for passive oxygen separation membranes [PDF]

open access: yes, 2010
Dense ceramic oxygen separation membranes can pass oxygen perm-selectively at elevated temperature and have potential for improving the performance and reducing the cost of several industrial processes: such as the conversion of natural gas to syngas,

Mathematical modelling of vortex structures in the channel of an electrodialysis cell with ion-exchange membranes of different surface morphology

open access: yesКонденсированные среды и межфазные границы, 2022
One of the ways to obtain membranes with electroconvection as the dominant mechanism of ion transport is to optimise the surface of known brands of commercial heterogeneous membranes by changing their manufacturing technology.

Profiled Ion Exchange Membranes: A Comprehensible Review [PDF]

open access: yesInternational Journal of Molecular Sciences, 2019
Profiled membranes (also known as corrugated membranes, micro-structured membranes, patterned membranes, membranes with designed topography or notched membranes) are gaining increasing academic and industrial attention and recognition as a viable alternative to flat membranes.

Comparison of Physicochemical Properties of Two Types of Polyepichlorohydrin-Based Anion Exchange Membranes for Reverse Electrodialysis

open access: yesMembranes, 2022
The development of the most effective, suitable and economic ion-exchange membranes is crucial for reverse electrodialysis (RED)—the most widely studied process to harvest salinity gradient energy from mixing seawater and river water.

Investigation of Electrochemical and Morphological Properties of Mixed Matrix Polysulfone-Silica Anion Exchange Membrane [PDF]

open access: yes, 2016
Mixed matrix anion exchange membranes (AEMs) were synthesized using dry-wet phase inversion. The casting solutions were prepared by dispersing finely ground anion-exchange resin particles in N,N-dimethylacetamide (DMAc) solutions of polysulfone (PSf ...

Perspective: Morphology and ion transport in ion-containing polymers from multiscale modeling and simulations

open access: yesFrontiers in Chemistry, 2022
Ion-containing polymers are soft materials composed of polymeric chains and mobile ions. Over the past several decades they have been the focus of considerable research and development for their use as the electrolyte in energy conversion and storage ...

Structurally simple lipid bilayer transport agents for chloride and bicarbonate [PDF]

open access: yes, 2011
A new series of structurally simple compounds containing thiourea groups have been shown by a combination of ion-selective electrode and 13C NMR techniques to be potent chloride-bicarbonate exchange agents that function at low concentration in POPC and ...

Water Splitting and Transport of Ions in Electromembrane System with Bilayer Ion-Exchange Membrane

open access: yesMembranes, 2020
Bilayer ion-exchange membranes are mainly used for separating single and multiply charged ions. It is well known that in membranes in which the layers have different charges of the ionogenic groups of the matrix, the limiting current decreases, and the ...

Study of the Electrical Conductivity of Ion-Exchange Resins and Membranes in Equilibrium Solutions of Inorganic Electrolytes

open access: yesMembranes, 2022
The study of the electrical conductivity of ion-exchange membranes in equilibrium electrolyte solutions is of great importance for the theory of membrane processes, in particular for practical electrodialysis.
