This year’s Nano Research Award, which is sponsored by Tsinghua University Press (TUP) and Springer Nature, was presented to two celebrated researchers in Changsha, China on June 23rd. Omar M. Yaghi, the James and Neeltje Tretter Chair Professor of Chemistry at the University of California, Berkeley received the award for pioneering a new field of research known as reticular chemistry. This chemistry has led to the discovery of several new classes of extended structures called metal-organic frameworks, covalent organic frameworks, zeolitic imidazolate frameworks, and molecular weaving.

Adsorption is a process which plucks water molecules from air that has less than 100% relative humidity by attaching them to the surface of a solid material. The molecules are held there by electrostatic connections called Van der Waals forces that link them with the molecules of the pertinent surface. To collect a lot of water this way therefore requires a material that has two properties. One is a large surface area. The other is an appropriate Van der Waals response. Experimental traps that employ this principle have been made using substances called metal-organic frameworks.
