Carbon Dioxide Molecules (IMAGE) DOE/SLAC National Accelerator Laboratory Caption In a new study, researchers trapped carbon dioxide molecules in highly porous nanoparticles called MOFs, flash-froze the particles in liquid nitrogen and examined them with cryo-EM at a Stanford-SLAC Facilities. The process allowed them to obtain the first atomic-scale images of individual CO2 molecules within the particle's cage-like pores.
