Relationship between zeolite structure and capture capability for radioactive cesium and strontium.
TL;DR: Ion-exchange experiments revealed that Cs+ exhibited an enhanced affinity to zeolites with high Si/Al ratios, which could be explained by the dielectric theory and micropore channels with large apertures were beneficial for achieving fast ion-ex exchange kinetics, especially in the case of Sr2+.

Structural effects of amine polymers on stability and energy efficiency of adsorbents in post-combustion CO2 capture
TL;DR: In this article, the effects of polymer structures on the CO2 adsorption capacity, kinetics, adsorbent stability, and regeneration heat of adsorbents using four amine polymers with different molecular weights, amine distributions, and ppm-level metal impurities.

TL;DR: In this paper, bifunctional surfactants are used to direct the formation of mesoporous and microporous length scales simultaneously and thus yield MFI (ZSM-5, one of the most important catalysts in the petrochemical industry) zeolite nanosheets that are only 2 nm thick.

Macroporous Silica with Thick Framework for Steam‐Stable and High‐Performance Poly(ethyleneimine)/Silica CO2 Adsorbent
TL;DR: A highly macroporous silica (MacS), synthesized by secondary sintering of fumed silica, is compared with various mesoporous silicas with different pore structures as a support for PEI to show the most promising CO2 adsorption kinetics and capacity as well as steam stability.
