Read moreA new way to look at metal organic frameworks
An international collaboration of scientists has developed a technique they dubbed 'gas adsorption crystallography' that provides a new way to study the process by which metal-organic frameworks (MOFs) are able to store immense volumes of gases such a carbon dioxide, hydrogen and methane. This new look at MOFs led to a discovery that holds promise for the improved design of MOFs tailored specifically for carbon capture, or for the use of hydrogen and natural gas fuels.
