Kolokvij IRB-a: Mechanochemistry and Porous Liquids - New Technologies for Sustainable Processes

New approaches are needed to rise to the global challenge of moving toward more sustainable technologies. In this talk I will outline our efforts in the areas of mechanochemistry and porous liquids. As well as having potential applications, both of these technologies require greater basic understanding than exists at present, which makes them stimulating areas for fundamental as well as applied research.

Mechanochemistry: Mechanochemistry involves the use of mechanical force (grinding, shear, compression) to induce chemical reactions. It potentially provides a more sustainable way of doing synthesis than traditional methods since it avoids or greatly reduces the use of solvents. However, mechanistically it remains poorly understood. Our work on mechanistic understanding, scale-up and commercialization through continuous twin-screw extrusion techniques and some recent Life Cycle Assessments will be presented.

Porous Liquids: Porosity is a fundamental property of materials which has until recently only been associated with the solid state. We conceptualized porous liquids as a counter-intuitive class of materials, in 2007 and they have now become a growing field of study worldwide. Since they combine fluidity with porosity they can be developed for use in continuous gas separation processes. Our work towards applying them for biogas upgrading will be presented. The use of this concept to make liquids with unusually high compressibility will also be presented.

Biography

Professor Stuart James is Chair of Inorganic Chemistry at Queen’s University Belfast, having previously worked at the Universities of Bristol, Cambridge, Imperial College, Louis Pasteur (Strasbourg) and Utrecht. He founded the field of Porous Liquids and has helped to advance mechanochemical synthesis. Complimenting his fundamental research he has co-founded two spin-out companies, MOF Technologies (now Nuada) and Porous Liquid Technologies.
