Porous material made by mimicking deep Earth conditions

An aerial photo showing a large pool of water that's bright blue in the middle, surrounded by a yellow area and rusty orange zone on the outside. A tiny footpath and people near this spring show it must be at least 100m across.

Extreme temperature changes water’s properties so it can replace organic solvent

By heating water far above its boiling point inside a closed flask, scientists can use it instead of an organic solvent to prepare a covalent organic framework (COF) material – a method they dubbed geomimetic hydrothermal synthesis because it recreates some of the extreme conditions deep under the Earth’s crust.
