Giulio Ragazzon, Laboratory of Driven Chemical Processes
Giulio Ragazzon is the principal investigator of the Laboratory of Driven Chemical Processes. His research interests evolved from photochemistry to molecular machines, self-assembling systems and nanomaterials. He is the recipient of multiple awards, including the European Young Chemist Award.
Summary:
The principles regulating directional motion at the macroscale or at molecular level are different. Mechanisms operating at the nanoscale are called ratchets, and underlie the operation of molecular machines. Since molecular motors can perform work, mastering their operating principles may enable energetically unfavourable processes, that seemingly overcome thermodynamic barriers.
In this talk, experimental efforts dealing with the investigation of artificial molecules will serve as a basis to discuss how energy can be exploited to drive molecular motion and the assembly of high-energy structures, revealing common underlying principles.
As a junior principal investigator, I will take this opportunity to present how my research background is evolving in future directions, broadly related to the field of supramolecular and system’s chemistry. The overarching goal of my group’s research is to unravel how energy sources can drive non-equilibrium processes at the molecular level.
Challenges:
– developing methods to monitor reaction fluxes – rather than concentrations – in chemical reaction networks;
– developing methods to gain information on steps other than the rate-determining ones;
– transducing energy (absorbing and transferring it), ideally for diffused energy harvesting;
– entering Pasteur’s quadrant: connecting with societal needs and engaging with use-inspired basic research – entering Pasteur’s quadrant
