Ms Olena Makhotkina (MaMASELF, Universitรฉ de Rennes1, Rennes, France)22/05/2014, 10:45In crystal engineering, intermolecular interactions play a crucial role, and give the possibility to create co-crystals. One of these interactions is halogen bond. As an analogue to the hydrogen bonding, it is a non-covalent interaction between covalently bounded halogen atom and Lewis base. This interaction is essentially of electrostatic nature. Indeed, the electron cloud around halogen atom...Go to contribution page

Mr Simone Sala (MaMaSELF)23/05/2014, 09:00The main limitations to the widespread deployment of solar energy technologies have historically been their limited reliability and storage-related complexities. These correlated issues have been recently addressed through the development of solar-driven redox thermochemical cycles based on metal oxides, probably the most studied of which has been the Zn/ZnO cycle. All of them are based on a...Go to contribution page
