Ion selectivity of graphene nanopores
Nature Communications, 2016 Sub-nanometer graphene nanopores are usually required to create graphene-based reverse osmosis membranes. Here, Rollings et al.show that membranes with larger pores are highly ion selective and a hundred times more permeable to potassium ions than to ...

Two-fluid model for the simultaneous flow of colloids and fluids in porous media [PDF]
, 2011 To describe the velocities of particles such as ions, protein molecules and colloids dispersed or dissolved in a fluid, it is important to also describe the forces acting on the fluid, including pressure gradients and friction of the fluid with the ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In this study, the actual route of methylene blue (MB) dye adsorption by using fabricated polyfunctional activated carbon–copper oxide nanowires (AC@CuO‐NWs) from bulky wastewater bodies has been investigated. To better understand the exact pathway of the adsorption process, a prominent statistical physics formalism or grand canonical ...

On the understanding and feasibility of “Breakthrough” Osmosis [PDF]
, 2019 Osmosis is the movement of solvent across a permselective membrane induced by a solute-concentration gradient. Now in ‘Forward Osmosis’ it is empirically observed that the diffusion of the solute is counter to that of the solvent i.e. there is so-called “

State‐of‐the‐Art and Synthetic Challenges for Hydrosilane Production
Chemistry – A European Journal, EarlyView.The synthesis of hydrosilanes is currently energy intensive and their recycling is not considered. However, these compounds are important in many industrial fields but also for the valorization of oxygenated waste, towards a circular economy. This review compares the available synthetic routes and highlights the remaining challenges for the production ...

Salinity Reduction of Real Produced Waters via Assisted Reverse Electrodialysis
Chemical Engineering Transactions, 2023 Produced waters (PWs) are waste streams generated during the crude oil extraction processes. The management of these wastewaters is complicated by the large volumes extracted during the oil recovery operations: these depends on the life of the oil-well ...
