The separation of gaseous hydrocarbon isomers by thermal diffusion has been demonstrated. Experiments were made in a Clusius column and mixtures analyzed by a mass spectrometer. Binary mixtures of ...

A membrane that separates organic solvent molecules based on their shape and size could dramatically cut costs associated with preparing valuable polymer feedstocks, such as p-xylene. It works as part ...

A new metal-organic framework material that sorts hydrocarbon molecules by shape could lower the cost of gasoline and also make the fuel safer by reducing the need for certain additives that have been ...
