Stuart travels to Mendoza

Stuart visited Mendoza in May.  He attended as well the Physical Chemistry and Inorganic Chemistry National Meeting (XX CAFQI)in Villa Carlos Paz in Córdoba where he  was a plenary speaker and where he spoke about his work in the fields of mechanochemical synthesis and porous liquids.

MECHANOCHEMICAL SYNTHESIS:
Mechanochemical synthesis involves initiating chemical reactions through the input of mechanical energy. It is of considerable and fundamental interest to understand how such reactions occur from a mechanistic point of view and to scale them up to commercial levels. It is attractive for industrial application since it can often be performed with no, or minimal, added solvent potentially providing cost savings and greater sustainability. The aspects briefly discussed included, mechanistic models, various types of synthesis, and the use of twin screw extrusion (TSE) techniques to scale-up mechanochemical synthesis on a continuous basis. The latter approach has enabled scale-up synth

         POROUS LIQUIDS:
 Permanent porosity is normally only associated with the solid state. Solids can support empty spaces due to their fixed, rigid structures. It is initially counter-intuitive that liquids, with their fluidic nature, could also support open cavities. However, with appropriate molecular design this can be achieved. Prof James presented his group’s recent work on the use of empty organic hosts dissolved, at very high concentration, in solvents which are too bulky to enter the host interiors. This approach provides porous liquid phases into which unusually, and interestingly, large amounts of gas can be dissolved due to the presence of empty pores. As well as fundamental considerations, some future perspectives for porous liquids were given.
