In supramolecular chemistry, relatively weak non-covalent interactions (Van der Waals forces, electrostatic interactions) are responsible for the self-assembly of tailor-made molecular building blocks into larger nanostructures (wires, bilayers and capsules). Examples are often inspired by structures that exist in nature (biopolymers, membranes and cells). These materials are diamagnetic, which implies that they experience magnetic forces, but only in intense magnetic fields. In this project, we plan to use strong magnetic levitation and alignment forces to investigate the relationship between the structure of organic nanosystems and their properties (chirality, elasticity and permeability). While experiments have been performed on ensembles, they have never been done on individual nano-objects. To overcome ensemble averaging we aim to develop an in-situ optical microscope that is able to detect the magnetic-field induced changes on a single organic nanostructure. The student will also be involved in helping external users carry out related experiments in high magnetic fields here at the HFML.

Description

We seek highly talented, enthusiastic, and exceptionally motivated candidates with an MSc degree in Physics, Physical Chemistry or Material Science. Experience in optical spectroscopy and multidisciplinary research is highly desirable, but not essential. The candidate must have strong communication skills, including fluency in written and spoken English.

Research The Soft Condensed Matter & Nanomaterials group of the High Field Magnet Laboratory (HFML) uses strong magnetic fields to manipulate seemingly non-magnetic materials. The focus of our work is the investigation of the physical properties of organic nanostructures, such as supramolecular self-assemblies, polymeric nanostructures and biomaterials, using magnetic levitation and magnetic alignment forces. Our research is embedded in the Institute for Molecules and Materials at Radboud University in Nijmegen and is well-resourced through external funding.
