Using fast-reactive crosslinkers to modulate the internal structure of thermoresponsive microgels
Ballin Elisa, Brasili Francesco, Sztucki Michael +3
The internal architecture of poly(N-isopropylacrylamide) (PNIPAM) microgels, which switches from fuzzy-sphere to star-like when the standard N,N'-methylenebis(acrylamide) (BIS) cro…
A single-chain nanoparticle-based mean-field theory for associative polymers
Marco Cappa, Stefano Chiani, Francesco Sciortino +1
Associative polymers are a class of polymers containing attractive stickers that can reversibly bind to each other. Their fully-bonded state gives rise, in dilute conditions, to a…
Entropy-driven phase behaviour of all-DNA associative polymers
Francesco Tosti Guerra, Federico Marini, Francesco Sciortino +1
Associative polymers (APs) with reversible, specific interactions between ``sticker'' sites exhibit a phase behavior that depends on a delicate balance between distinct contributio…
A Falsifiability Test for Classical Nucleation Theory
Camilla Beneduce, Diogo E. P. Pinto, Lorenzo Rovigatti +4
Classical nucleation theory (CNT) is built upon the capillarity approximation, i.e., the assumption that the nucleation properties can be inferred from the bulk properties of the m…
A phase-field model for solutions of DNA-made particles
Marco Cappa, Francesco Sciortino, Lorenzo Rovigatti
We present a phase-field model based on the Cahn-Hilliard equation to investigate the properties of phase separation in DNA nanostar systems. Leveraging a realistic free-energy fun…
Solid-liquid interfacial free energy from computer simulations: Challenges and recent advances
Nicodemo Di Pasquale, Jesus Algaba, Pablo Montero de Hijes +12
The theory of interfacial properties in liquid-liquid or liquid-vapour systems is nearly 200 years old. The advent of computational tools has greatly advanced the field, mainly thr…

Giovanni Mattiotti, Manuel Micheloni, Lorenzo Petrolli +3
The cowpea chlorotic mottle virus (CCMV) has emerged as an exemplary model system to assess the balance between electrostatic and topological features of ssRNA viruses, specificall…
Diffusion, viscosity and linear rheology of valence-limited disordered fluids
Samuel S. Gomez, Lorenzo Rovigatti
We numerically investigate the dynamics and linear rheology of disordered systems made of patchy particles, focussing on the role of valence, temperature and bonding mechanism. We…

Sophisticated statistical mechanics approaches and human intuition have demonstrated the possibility to self-assemble complex lattices or finite size constructs, but have mostly on…
Entropy-driven phase behavior of associative polymer networks
Lorenzo Rovigatti, Francesco Sciortino
Polymer chains decorated with a fraction of monomers capable of forming reversible bonds form transient polymer networks that are important in soft and biological systems. If chain…
Structure and elasticity of model disordered, polydisperse and defect-free polymer networks
