Crystal-to-crystal transition of ultrasoft colloids under shear
J. Ruiz-Franco, J. Marakis, N. Gnan +5
Ultrasoft colloids typically do not spontaneously crystallize, but rather vitrify, at high concentrations. Combining in-situ rheo-SANS experiments and numerical simulations we show…
Internal structure and swelling behaviour of in silico microgel particles
Lorenzo Rovigatti, Nicoletta Gnan, Emanuela Zaccarelli
Microgels are soft colloids that, in virtue of their polymeric nature, can react to external stimuli such as temperature or pH by changing their size. The resulting swelling/deswel…
Equilibrium gels of limited valence colloids
Francesco Sciortino, Emanuela Zaccarelli
Gels are low-packing arrested states of matter which are able to support stress. On cooling, limited valence colloidal particles form open networks stabilized by the progressive in…
"In silico" synthesis of microgel particles
Nicoletta Gnan, Lorenzo Rovigatti, Maxime Bergman +1
Microgels are colloidal-scale particles individually made of crosslinked polymer networks that can swell and deswell in response to external stimuli, such as changes to temperature…
