Tossell's new computer modelling studies found that the molecule might be well-suited for removing carbon dioxide directly from air, in addition to its previously described potential use as an absorbent for carbon dioxide from electric power plants and other smoke stacks.

'It is also conceivable that living organisms may be developed which are capable of replacing structurally ion receptors within their cell membranes,' the report noted.

These findings are slated for publication in the Aug 3 issue of Inorganic Chemistry.
