Capture And Release

A solution of acylated polyethylenimine absorbs CO2 at low temperatures and draws water from high-salt saline due to the high osmotic pressure, while it liberates CO2 after phase separation by mild heating and releases water into low-salt saline.

Liquid Liquid Phase Separation

Salt induces liquid–liquid phase separation (LLPS) of the aqueous solutions of a dendrimer. LLPS occurs by cooling at low salt concentration and by heating at high salt concentration.
