Monte Carlo simulations of the Asakura-Oosawa model for colloid-polymer mixtures confined between two parallel repulsive structureless walls are presented and analyzed in the light of current theories on capillary condensation and interface localization transitions. Choosing a polymer-to-colloid size ratio...

We study the structural and dynamic properties of a polymer melt in the vicinity of an adhesive solid substrate by means of Molecular Dynamics simulation at various degrees of surface adhesion. The properties of the individual polymer chains are...

Self-propelled Vicsek particles at low speed and low density.

Physical review. E

Rubio Puzzo ML, De Virgiliis A, Grigera TS.
PMID: 31212496
Phys Rev E. 2019 May;99(5):052602. doi: 10.1103/PhysRevE.99.052602.

We study through numerical simulation the Vicsek model for very low speeds and densities. We consider scalar noise in two and three dimensions and vector noise in three dimensions. We focus on the behavior of the critical noise with...

Colonization Ability and Impact on Human Gut Microbiota of Foodborne Microbes From Traditional or Probiotic-Added Fermented Foods: A Systematic Review.

Frontiers in nutrition

Roselli M, Natella F, Zinno P, Guantario B, Canali R, Schifano E, De Angelis M, Nikoloudaki O, Gobbetti M, Perozzi G, Devirgiliis C.

Front Nutr. 2021 Jul 29;8:689084. doi: 10.3389/fnut.2021.689084. eCollection 2021.

A large subset of fermented foods act as vehicles of live environmental microbes, which often contribute food quality assets to the overall diet, such as health-associated microbial metabolites. Foodborne microorganisms also carry the potential to interact with the human...

Confinement effects on phase behavior of soft matter systems.

Soft matter

Binder K, Horbach J, Vink R, De Virgiliis A.
PMID: 32907146
Soft Matter. 2008 Jul 16;4(8):1555-1568. doi: 10.1039/b802207k.

When systems that can undergo phase separation between two coexisting phases in the bulk are confined in thin film geometry between parallel walls, the phase behavior can be profoundly modified. These phenomena shall be described and exemplified by computer...

Impact of supplementation with a food-derived microbial community on obesity-associated inflammation and gut microbiota composition.

Genes & nutrition

Roselli M, Devirgiliis C, Zinno P, Guantario B, Finamore A, Rami R, Perozzi G.

Genes Nutr. 2017 Oct 04;12:25. doi: 10.1186/s12263-017-0583-1. eCollection 2017.

BACKGROUND: Obesity is a complex pathology associated with dysbiosis, metabolic alterations, and low-grade chronic inflammation promoted by immune cells, infiltrating and populating the adipose tissue. Probiotic supplementation was suggested to be capable of counteracting obesity-associated immune and microbial alterations,...
