“Manipulating controlled radical polymerization to control architecture, functionality and morphology”
by Athina Anastasaki (University of California, Santa Barbara https://scholar.google.co.uk/citations?user=wFpF2_kAAAAJ&hl=en)
In this talk the development of new controlled radical polymerization strategies will be presented, including atom transfer radical polymerization (ATRP), reversible addition-fragmentation chain transfer (RAFT) polymerization and emulsion polymerization. These synthetic strategies give access to advanced materials consisting of hydrophilic, hydrophobic, semi-fluorinated and functional segments. Although traditional polymerization strategies require various parameters to be optimized to achieve a high degree of control over molecular weight and dispersity, this work demonstrates that one set of universal conditions can be achieved. These universal conditions result in efficacious polymerization of different classes of monomers, including acrylates, methacrylates and styrene. The facile nature of these conditions, combined with readily available reagents, will greatly expand the availability of tailored polymeric materials to all researchers. Ultimately, the synthesis of complex, sequence-controlled multiblock copolymers will reveal advanced materials that exhibit unique characteristics and morphologies.

"Polarisation and order in biological networks: equilibrium and (some) dynamics"
by Kristian Müller-Nedebock, Dept of Physics, Stellenbosch University South Africa (www)
The mechanical and transport properties of a cell depend on the precise nature of networks which make up the cytoskeleton. The distribution and orientation of filaments within the finite region of the cell also vary with position within the cell and can be imaged. Molecular dynamics simulations show that confinement affects the orientation and distribution of filaments within the cell [Azari, A. & Müller-Nedebock, K. K. EPL (2015)]. A monomer ensemble technique allows us to understand branching and cross-linking in finite networks consisting of stiff filaments. We also briefly discuss active cross-linkers in networks, restricting our view to the one-dimensional contractile ring, and two-dimensional motility assays [Mebwe Pachong, S. & Müller-Nedebock, K. K. EPJE (2017)].
