Our seminar tomorrow, 2nd November will be given by Luciana De Matos, University of Sheffield. The title of the talk is “Crystal Engineering of Polymorphic Systems” and abstract reads:
“The peculiarity of polymorphic materials, which can adopt different crystal structures whilst maintaining identical chemical constitution, makes these systems a target of great industrial and academic interest. The latter arises from consequent dramatic changes to these compounds’ physical properties upon polymorphic transformation. The exploration of such structural-related characteristics is therefore significant to a range of industries since the commercial market is swamped with polymorphic materials (e.g. chocolate, paracetamol and diamonds) which require control due to both quality assurance and patent regulations.
A summary of purposely developed methods which were successfully employed to manipulate the crystal quality and achieve complete polymorph selection will be presented. This review will account experimental set-ups used to monitor polymorph nucleation, growth and interconversion in real-time from both solution and melt states while detailing the use of solution speciation, impurity contamination and ultrasound irradiation techniques."
