porous

Unlike previously reported porous organic crystals, the Janus crystals combine water-collection and water-delivery functions at their surface, creating a highly efficient water harvesting process that maximizes the amount of collected water at ambient conditions.

Regarding the Rams’ bungling offense and porous defense, I’m reminded of advice given to me as a child.

Now, chemists at the University of California, Berkeley, have discovered that a porous material can act like a sponge to capture CO2 at temperatures close to those of many industrial exhaust streams.

These synthetic porous materials of interest to chemists specializing in selective encapsulation include such buzzwords as metal-organic frameworks, covalent organic frameworks, hydrogen-bonded organic frameworks, and zeolites.

While the defence looked in good nick against New Zealand, it was markedly porous against the Wallabies.
