Phytoglycogen (PG) nanoparticles are hyperbranched, dendritic polymers of glucose that are produced as compact nanoparticles in the kernels of sweet corn. Our measurements of their structure, morphology, hydration and mechanical properties illustrate the unique properties of native PG nanoparticles: they are soft, porous, hairy and hydrated. These physical properties, combined with their...
This talk reviews recent studies of the dynamical and mechanical behaviour of nanocolloidal soft glassy materials using Rheo-XPCS, x-ray photon correlation spectroscopy with in situ rheology [1]. Rheo-XPCS allows for simultaneous studies of the mechanics and nanoscale dynamics of materials over a wide range of timescales from milliseconds to hours. As such, it is an outstanding tool to...
Classical experiments, typically performed using bulk continuous matter can be applied for granular systems to better understand their properties, and explore the analogies between granular and bulk continuous systems. While the classic pendant drop experiment can be
used to measure the interfacial tension between fluids, here we perform the granular version of the pendant drop experiment....
Electrohydrodynamics of droplets immersed in an immiscible carrier fluid was first explored in a pioneering paper by G. I. Taylor who formulated the weakly conducting or leaky dielectric model and predicted the steady drop shape in the small-deformation limit. Contemporary literature in electrohydrodynamic studies focuses primarily on the deformations of single droplets. On the other hand, the...
