Molecular origin of slippery behaviour in tethered liquid layers
Fabio Rasera, Isaac J. Gresham, Antonio Tinti +2
Slippery covalently attached liquid surfaces (SCALS) are a family of nanothin polymer layers with remarkably low static droplet friction, characterised by a low contact angle hyste…
The surface tension of Martini 3 water mixtures
Lorenzo Iannetti, Sonia Cambiaso, Fabio Rasera +4
The Martini model, a coarse-grained forcefield for biomolecular simulations, has experienced a vast increase in popularity in the past decade. Its building-block approach balances…
Chemical Physics of Controlled Wettability and Super Surfaces
Carolina Brito, Hans-Jürgen Butt, Alberto Giacomello
Wetting phenomena are widespread in both natural and technological contexts. Despite the well-established nature of this scientific field and our extensive knowledge of its underly…
Bubbles enable volumetric negative compressibility in metastable elastocapillary systems
Davide Caprini, Francesco Battista, Pawel Zajdel +11
Although coveted in applications, few materials expand when subject to compression or contract under decompression, i.e., exhibit the negative compressibility phenomenon. A key ste…
What keeps nanopores boiling
Alberto Giacomello
The liquid to vapour transition can occur at unexpected conditions in nanopores, opening the door to fundamental questions and new technologies. The physics of boiling in confineme…
An atomistically informed multiscale approach to the intrusion and extrusion of water in hydrophobic nanopores
Gonçalo Paulo, Alberto Gubbiotti, Alberto Giacomello
Understanding intrusion and extrusion in nanoporous materials is a challenging multiscale problem of utmost importance for applications ranging from energy storage and dissipation…
Local grafting heterogeneities control water intrusion and extrusion in nanopores
Sonia Cambiaso, Fabio Rasera, Antonio Tinti +4
Hydrophobic nanoporous materials can be intruded by water only by exerting an external action, typically increasing pressure. For some materials, water extrudes when the pressure i…
Can one predict a drop contact angle?
Marion Silvestrini, Antonio Tinti, Alberto Giacomello +1
The study of wetting phenomena is of great interest due to the multifaceted technological applications of hydrophobic and hydrophilic surfaces. The theoretical approaches proposed…
Hierarchical macro-nanoporous metals for leakage-free high-thermal conductivity shape-stabilized phase change materials
Yaroslav Grosu, Yanqi Zhao, Alberto Giacomello +6
Impregnation of Phase Change Materials (PCMs) into a porous medium is a promising way to stabilize their shape and improve thermal conductivity which are essential for thermal ener…
Collapse of superhydrophobicity on nanopillared surfaces
Matteo Amabili, Alberto Giacomello, Simone Meloni +1
The mechanism of the collapse of the superhydrophobic state is elucidated for submerged nanoscale textures forming a three-dimensional interconnected vapor domain. This key issue f…
Wetting and cavitation pathways on nanodecorated surfaces
Matteo Amabili, Emanuele Lisi, Alberto Giacomello +1
In this contribution we study wetting and nucleation of vapor bubbles on nanodecorated surfaces via free energy molecular dynamics simulations. The results shed light on the stabil…
Unraveling the Salvinia paradox: design principles for submerged superhydrophobicity
Matteo Amabili, Alberto Giacomello, Simone Meloni +1
The complex structure of the Salvinia molesta is investigated via rare event molecular dynamics simulations. Results show that a hydrophilic/hydrophobic patterning together with a…
Wetting hysteresis induced by nanodefects
Alberto Giacomello, Lothar Schimmele, Siegfried Dietrich
Wetting of actual surfaces involves diverse hysteretic phenomena stemming from ever-present imperfections. Here we clarify the origin of wetting hysteresis for a liquid front advan…
