LINCHPIN: A platform to LINk between CHemistry and PhysIcs of colloidal Nanomaterials

The LINCHPIN project focuses on understanding the physical properties of precursor molecules, pre-nucleation clusters, nuclei, and nanostructures. It also aims to gain a perspective on the interdependence between physical and chemical aspects of nanoparticle nucleation.

This project is supported by the European Research Council (ERC).
