We investigate dynamical heterogeneities in the collective relaxation of a concentrated microgel system, for which the packing fraction can be conveniently varied by changing the temperature. The packing fraction dependent mechanical properties are characterised by a fluid-solid transition, where the system properties switch from a viscous to an elastic low-frequency behaviour. Approaching this...

متن کاملCrystal structure of highly concentrated, ionic microgel suspensions studied by neutron scattering.
We present a neutron-scattering investigation of the crystal structure formed by pH -sensitive poly(2-vinylpyridine) microgel particles with 5 wt % of cross-linker. We focus on highly swollen particles and explore concentrations ranging from below close packing to well above close packing, where the particles are forced to shrink and/or interpenetrate. The crystal structure is found to be rando...
متن کاملSelf‐Regulated and Temporal Control of a “Breathing” Microgel Mediated by Enzymatic Reaction
Naturally occurring systems have the ability to self-regulate, which plays a key role in their structural and functional adaptation. The autonomous behavior in living systems is biocatalytically controlled by the continuous consumption of energy to remain in a non-equilibrium condition. In this work, we show the construction of a self-regulated "breathing" microgel that uses chemical fuels to k...
