Soft ULC Microgels at the Interface Interact and Flow as Hertzian-Like Colloids
José Ruiz-Franco, Tom Höfken, Maximilian M. Schmidt +3
Soft pair potentials predict a reentrant liquid phase for high concentrations, a behavior not observed experimentally. Here, very soft microgels confined at an oil-water interface…
Inducing mechanical self-healing in glassy polymer melts
José Ruiz-Franco, Andrea Giuntoli
Glassy polymer melts such as the plastics used in pipes, structural materials, and medical devices are ubiquitous in daily life. They accumulate damage over time due to their use,…
Auxetic polymer networks: The role of crosslinking, density and disorder
Andrea Ninarello, José Ruiz-Franco, Emanuela Zaccarelli
Low-connectivity polymer networks were recently found to behave auxetically when subjected to small tensions, that is, their Poisson's ratio becomes negative. In addition, for…
Interfacial fluid rheology of soft particles
Maximilian M. Schmidt, José Ruiz-Franco, Steffen Bochenek +3
In situ interfacial rheology and numerical simulations are used to investigate microgel monolayers in a wide range of packing fractions, . The heterogeneous particle compre…
Structure and elasticity of model disordered, polydisperse and defect-free polymer networks
Valerio Sorichetti, Andrea Ninarello, José Ruiz-Franco +5
The elasticity of disordered and polydisperse polymer networks is a fundamental problem of soft matter physics that is still open. Here, we self-assemble polymer networks via simul…
Link between morphology, structure and interactions of composite microgels
Rodrigo Rivas-Barbosa, José Ruiz-Franco, Mayra A. Lara-Peña +5
We combine small angle scattering experiments and simulations to investigate the internal structure and interactions of composite Poly(N-isopropylacrylamide)-Poly(ethylene glycol)…
Onset of criticality in hyper-auxetic polymer networks
Andrea Ninarello, José Ruiz-Franco, Emanuela Zaccarelli
Against common sense, auxetic materials expand or contract perpendicularly when stretched or compressed, respectively, by uniaxial strain, being characterized by a negative Poisson…
Static and Dynamic Properties of Block-Copolymer Based Grafted Nanoparticles Across the Non-Ergodicity Transition
Daniele Parisi, Jose Ruiz-Franco, Yingbo Ruan +3
We present a systematic investigation of static and dynamic properties of block copolymer micelles with crosslinked cores, representing model polymer-grafted nanoparticles, over a…
Static and Dynamic Properties of Block-Copolymer Based Grafted Nanoparticles Across the Non-Ergodicity Transition
Daniele Parisi, José Ruiz-Franco, Yingbo Ruan +4
We present a systematic investigation of static and dynamic properties of block copolymer micelles with crosslinked cores, representing model polymer-grafted nanoparticles, over a…
Tuning the rheological behavior of colloidal gels through competing interactions
José Ruiz-Franco, Fabrizio Camerin, Nicoletta Gnan +1
We study colloidal gels formed by competing electrostatic repulsion and short-range attraction by means of extensive numerical simulations under external shear. We show that, upon…
Microgels at interfaces behave as 2D elastic particles featuring reentrant dynamics
Fabrizio Camerin, Nicoletta Gnan, José Ruiz-Franco +3
Soft colloids are increasingly used as model systems to address fundamental issues such as crystallisation and the glass and jamming transitions. Among the available classes of sof…
Multi-Particle Collision Dynamics for a coarse-grained model of soft colloids
José Ruiz-Franco, Diego Jaramillo-Cano, Manuel Camargo +2
The growing interest in the dynamical properties of colloidal suspensions, both in equilibrium and under an external drive such as shear or pressure flow, requires the development…
Rheological investigation of gels formed by competing interactions: A numerical study
José Ruiz-Franco, Nicoletta Gnan, Emanuela Zaccarelli
A transition from solid-like to liquid-like behavior occurs when colloidal gels are subjected to a prolonged exposure to a steady shear. This phenomenon, which is characterized by…
Different scenarios of dynamic coupling in glassy colloidal mixtures
Marco Laurati, Tatjana Sentjabrskaja, José Ruiz-Franco +2
Colloidal mixtures represent a versatile model system to study transport in complex environments. They allow for a systematic variation of the control parameters, namely size ratio…
On the effect of the thermostat in non-equilibrium molecular dynamics simulations
José Ruiz-Franco, Lorenzo Rovigatti, Emanuela Zaccarelli
The numerical investigation of the statics and dynamics of systems in nonequilibrium in general, and under shear flow in particular, has become more and more common. However, not a…
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…
Intrinsic noise and deviations from criticality in Boolean gene-regulatory networks
Pablo Villegas, José Ruiz-Franco, Jorge Hidalgo +1
Gene regulatory networks can be successfully modeled as Boolean networks. A much discussed hypothesis says that such model networks reproduce empirical findings the best if they ar…
