Objective

Deliverables

  • Quantifying and controlling dynamics through rod characteristics

    We will study the effects of particle characteristics (length, aspect ratio, flexibility) on single particle, Brownian dynamics: (i) Single rod dynamics in highly ordered phases; (ii) Effect of nearby phase transitions on the collective dynamics. Novel theoretical models will be applied using a grand canonical description mimicking the experiments. Experiments on cellulose and thermo-responsive rods to approach phase transitions will provide validation of the modelling, using high-speed cameras to capture so far inaccessible relevant times scales.

  • Directing structure via chirality

    We will study the competition between chirality-induced twist and long-range positional order on the cholesteric phase and the structure of higher-order liquid crystalline states by tuning the molecular chirality using mixtures of two mutants with opposite chiral handedness in combination with X-ray scattering and fluorescence microscopy.

  • Understanding the molecular origin of dynamically percolated states

    We investigate: (i) The kinetic pathways that dominate temporal network formation in dispersions of rod-like particles; (ii) If translational and/or rotational motion provide the main route towards build-up and breakdown of cluster networks; (iii) The structure of the clusters for various types of interaction and external fields including flow; (iv) Whether the proximity to LC phases impacts upon the cluster size and structure, and if this affects the percolation threshold. We will use simulations, dynamical connectedness percolation theory, and in experiment a combination of dielectric spectroscopy, optical microscopy, rheology and radiation scattering.

  • Control of structure via confinement and quantification of the dynamics

    We will study the competition between Frank elasticity, surface anchoring and interfacial tensions via confinement and study the underlying dynamics.

  • Properties of the IN interface of entropy-dominated systems

    Create isotropic and nematic droplets to control the interplay between surface tension and Frank elasticity beyond the predetermined IN structures using microfluidics; Probe the structural behaviour of LC interfaces to understand interface behaviour of entropy-dominated systems

  • State diagram of the arrested states

    We will measure a state diagram for glass and gel formation as a function of rod characteristics and interactions. The experimental systems provide tuneable repulsive and attractive interactions.

  • Quantifying and controlling dynamics through interactions and concentration

    We will study effect of system characteristics (interactions, concentration) on structure and single particle, Brownian dynamics: (i) Single rod dynamics in highly ordered phases; (ii) Effect of nearby phase transitions on the collective dynamics. Novel theoretical models will be applied using a grand canonical description mimicking the experiments in WP 1.1 and 2.1. Experiments on cellulose and thermo-responsive rods to approach phase transitions will provide validation of the modelling, using high-speed cameras to capture so far inaccessible relevant times scales.

  • Supervisory board of the network

    Completion of supervisory board of the network.

  • Production of thermo-responsive virus-based systems with varying length and flexibility

    We will focus on the development of the following model system: Modification of rod-like virus particles such that the thickness can be tuned in situ. To this end, temperature responsive polymer shells will be grown onto the particle’s surface. The thickness and cross-link density of the polymer layer offers control over the volume fraction and the hardness of the rod particles. This deliverable will be a physical suspension of colloidal particles in a solvent.

  • Production of thermo-responsive silica rods

    Fluorescently labelled silica particles will be synthesised, offering a complimentary, non-chiral, alternative system to the virus system, facilitating the real-space study of self-assembly and phase behaviour, also in the presence of other colloidal particles and solvents. This deliverable will be a physical suspension of colloidal particles in a solvent.

  • Project identity set and launch of DiStruc web portal

    Project identity set in order to facilitate communication and create a visual identity to the project, DiStruc logo, brochure and a slide template will be created. The non-confidential general public area in the DiStruc web portal piloted by FOR will provide general background information which is not currently available in an accessible form to the general public. This information will enable interested educators, such as high school teachers, to integrate recently acquired knowledge into the curriculum early. Interested undergraduate students will find information complementing their classes. The program therefore will impact on the general public, and raise the interest in scientific research, from theory to advanced materials, thus taking an active role in advertising a career in research to young people. A restricted domain will be constructed in the web portal to which only the consortium will have access. Given the mix of PU and CO I have selected the more confidential dissemination level.
