A chemist from the University of California, Berkeley, was among the trio of scientists awarded the Nobel Prize for Chemistry on Wednesday.

Omar Yaghi, the Berkeley professor; Susumu Kitagawa from Kyoto University in Japan; and Richard Robson from the University of Melbourne in Australia were recognized for their work since the 1990s to develop a new form of molecular architecture that combines metal ions and carbon-based molecules, according to a release from the Royal Swedish Academy of Sciences, which administers the Nobel Prize.

The metal-organic frameworks can harvest water or store toxic gases. The release noted that the frameworks “may contribute to solving some of humankind’s greatest challenges.”

The release says the frameworks are essentially “rooms” because of the large spaces that form in the structure. A Nobel committee member compared it to Hermione Granger’s magical bag in the seventh Harry Potter book, the Associated Press reported. Her small bag eventually contained a tent, books and other provisions. Likewise, the frameworks look small but can hold a lot.

Since the trio’s discoveries, more than 100,000 metal-organic frameworks have been created, according to a news release from Berkeley.
