Capacitive deionization (CDI) for desalination and water treatment — past, present and future (a review)
TL;DR: Capacitive deionization (CDI) has attracted the interest of the community investigating water treatment technologies since the mid-1960s as mentioned in this paper, based on the recognition that high-surface-area electrodes, when electrically charged, can quantitatively adsorb ionic components from water, thereby resulting in desalination.

Separation of gases by pressure swing adsorption
TL;DR: The recent status of pressure swing adsorption (PSA) as a process for separating multicomponent gas mixtures is reviewed in this article, where applications of a new generation of adsorbents, such as zeolites, carbon molecular sieves, and pore engineered molecular sizers, are described in detail.

Axial diffusion in a cylinder with pulsed flow
H. Gordon Harris,Simon L. Goren +1 more
TL;DR: The theory for the rate of mass transfer through a long tube connecting two reservoirs of constant concentration with oscillatory flow in the tube is developed in this article, where the increase in transfer rate relative to that due to molecular diffusion alone is found as a function of three dimensionless groups, an oscillatory Reynolds number ωa2/v, an amplitude parameter A/a and the Schmidt number v/D.
