Switchable solvents and surfactants

I went to a fascinating talk yesterday on green chemistry by Professor Philip Jessop from Queen’s University, Canada. ¬†Prof. Jessop has created reversible switchable solvent and switchable surfactant systems which can be turned from ‘good’ to ‘poor’ behaviour by simply bubbling carbon dioxide through the system. ¬† With switchable solvents, the idea is to remove…
