A polyamine-functionalized covalent organic framework ... the humid CO 2 removal performance by dynamically optimizing polar carbon nanopores with the formation of local surface bound water.

It's called COF-999, which is short for Covalent Organic Frameworks. The term refers to a class of porous crystalline materials that have large pores, plenty of surface area, and low density.

Covalent bonding happens easily with carbon ... A soap is a sodium or potassium salt of long-chain fatty acids. It consists of polar and non-polar ends. The polar end is hydrophilic while the ...
