TLDR
The possible reductions in energy demand by state-of-the-art seawater Desalination technologies, the potential role of advanced materials and innovative technologies in improving performance, and the sustainability of desalination as a technological solution to global water shortages are reviewed.Abstract:
In recent years, numerous large-scale seawater desalination plants have been built in water-stressed countries to augment available water resources, and construction of new desalination plants is expected to increase in the near future. Despite major advancements in desalination technologies, seawater desalination is still more energy intensive compared to conventional technologies for the treatment of fresh water. There are also concerns about the potential environmental impacts of large-scale seawater desalination plants. Here, we review the possible reductions in energy demand by state-of-the-art seawater desalination technologies, the potential role of advanced materials and innovative technologies in improving performance, and the sustainability of desalination as a technological solution to global water shortages.read more

Theoretical evaluation of electrochemical cell architectures using cation intercalation electrodes for desalination
TL;DR: In this article, the authors used two-dimensional porous-electrode theory with concentrated solution transport to evaluate the performance of various cell architectures where flow occurs through open flow channels (OFCs) when two IHC electrodes comprised of nickel hexacyanoferrate (NiHCF) are used to store Na+ ions.

Understanding the pH-responsive behavior of graphene oxide membrane in removing ions and organic micropollulants
TL;DR: In this article, a multi-layered graphene oxide (GO) membrane was used to remove ionic and organic species from water at different pH levels, and it was found that at pH 7, the GO membrane exhibited high removal of multivalent cations/anions and all tested organics, regardless of their charges, sizes, or hydrophobic properties, but low removal of monovalent ions.

Photo Induced Membrane Separation for Water Purification and Desalination Using Azobenzene Modified Anodized Alumina Membranes
TL;DR: The photo induced permeation of water was promoted by the vaporization of water with the repetitive photo isomerization of azobenzene, and achieved the purification of water solutions, because dye molecules and a protein dissolved in aqueous solutions were not involved in the photo induced penetrated water.

High-flux and fouling-resistant reverse osmosis membrane prepared with incorporating zwitterionic amine monomers via interfacial polymerization
TL;DR: In this paper, N-aminoethyl piperazine propane sulfonate (AEPPS) was added into m-phenylenediamine (MPD) aqueous solution to react with trimesoyl chloride (TMC) via interfacial polymerization to fabricate zwitterionic thin film composite reverse osmosis membrane (TFCMZs).
Journal ArticleDOI
Constant flux crossflow filtration evaluation of surface-modified fouling-resistant membranes
TL;DR: A potential strategy to achieve fouling resistance in a membrane of a desired flux and rejection is to modify the surface of a more permeable (and perhaps lower rejection) membrane, thereby making the resulting modified membrane fouling-resistant but leaving it with the desired fluxand rejection characteristics.

A Survey of Structure−Property Relationships of Surfaces that Resist the Adsorption of Protein
TL;DR: In this paper, the authors used surface plasmon resonance spectroscopy and self-assembled monolayers (SAMs) to determine the characteristics of functional groups that give surfaces the ability to resist the nonspecific adsorption of proteins from solution.
