Microporous Polysulfones with Enhanced Separation Performance via Integration of the Triptycene Moiety [PDF]
, 2019 Here, we report the synthesis of two polysulfones containing either triptycene or phenolphthalein as the bulky bridging unit in the polymer backbone to investigate the influence of the rigid, unwieldy structures on chain rigidity, fractional free volume,

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems
Advanced Science, EarlyView.Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...
