  1. ESR8 experimental position with Eric Grelet: Directing through chirality the self-organization of complex fluids formed by colloidal rods and spheres

The competition between chirality-induced twist and long-range positional order will be studied in dense self-organized structures by tuning the molecular chirality using mixtures of two different mutants with opposite chiral handedness in combination with fluorescence microscopy, X-ray scattering, freeze-fracture techniques and optical tweezers. Different composites formed by our model system of colloidal rods (namely fd filamentous virus) and hard (like quantum dots) or soft (i.e. polymer) spheres will be studied, aiming in particular at decorating the topological defects. In order to monitor the self-assembly properties, biofunctionalization of the viral particles will also be performed during the research project.

Excellent candidates with commitment are sought for this ambitious, exciting, high level, inter- and multidisciplinary project. Applicants should be in possession of, or expect to attain, a Master’s in a relevant discipline (Chemistry, Physics, Materials science, Nanoscience). The position is full time. DiStruc offers highly competitive salaries in accordance with the MSCA-ITN regulations. We expect the Early Stage Researcher typically to start during the summer of 2016. 

Applications for this position have now CLOSED.

 

  1. ESR9 experimental position with Eric Grelet: Directing dynamics by rod characteristics & interactions: study at the single particle scale with a model system of colloidal rods

We will study effect of particle (length, aspect ratio, flexibility) and system characteristics (interactions, volume fraction) on single rod dynamics in highly ordered (meso)phases, focusing especially on the effect of nearby phase transitions on the collective dynamics. The PhD project will be performed using a model system of colloidal rods which can be visualized and tracked at the single particle scale. Experiments on functionalized (i.e. thermo-responsive) rods to approach continuously the phase transitions will provide original data thanks to high-speed cameras to capture so far inaccessible relevant times scales. This research work implying image analysis will be performed in close collaboration with theoreticians and computer simulators of the DiStruc network.​
