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.

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.
Abstract: The recent status of pressure swing adsorption (PSA) as a process for separating multicomponent gas mixtures is reviewed. The applications of a new generation of adsorbents, such as zeolites, carbon molecular sieves, and, more recently, pore engineered molecular sieves, are described in detail. The more important theories of adsorption from gas mixtures as well as those of the PSA process are described briefly. The commercial applications of PSA the process-present and potential-are discussed at length.

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.
