Molecular-sized bubbles in a liquid: free energy of formation beyond the capillarity approximation
J. Puibasset
We investigate the transient bubbles that spontaneously appear in a simple liquid using molecular simulations. The objective is to deduce the free-energy of formation of the bubble…
A statistical analysis of the first stages of freezing and melting of Lennard-Jones particles: Number and size distributions of transient nuclei
Patrice Porion, Joël Puibasset
The freezing/melting transition is at the heart of many natural and industrial processes. In the classical picture, the transition proceeds via the nucleation of the new phase, whi…
Equilibrium structure and shape of Ag and Pt nanoparticles grown on silica surfaces: from experimental investigations to the determination of a metal-silica potential
F. Ait Hellal, C. Andreazza-Vignolle, P. Andreazza +1
A combination of experimental and numerical calculations on metallic silver and platinum nanoparticles deposited on silica substrates is presented, with a focus on the metal-substr…
Are nucleation bubbles in a liquid all independent?
Joël Puibasset
The spontaneous formation of tiny bubbles in a liquid is at the root of the nucleation mechanism during the liquid-to-vapor transition of a metastable liquid. The smaller the bubbl…
Silver-Platinum nanoparticles and nanodroplets supported on silica surfaces: structure and chemical ordering
F. Ait Hellal, J. Puibasset, C. Andreazza-Vignolle +1
Stable and metastable metallic nanoparticles exhibit unique properties compared to the bulk, with potentially important applications for catalysis. This is in particular the case f…
A general relation between the largest nucleus and all nuclei distributions for free energy calculations
Joël Puibasset
Prediction of nucleation rates in first order phase transitions requires the knowledge of the barrier associated to the free energy profile . Molecular simulations offer a direc…
Monte-Carlo Multiscale Simulation Study of Argon Adsorption/Desorption Hysteresis in Mesoporous Heterogeneous Tubular Pores like MCM-41 or Oxidized Porous Silicon
Joël Puibasset
In a recent paper [J. Chem. Phys. 127, 154701 (2007)], a multiscale approach was introduced which allowed the calculation of adsorption/desorption hysteresis for fluid confined in…
Molecular simulation study of the heat capacity of metastable water between 100K and 300K
Joel Puibasset, P. Judeinstein, J. -M Zanotti
Molecular simulation study of the heat capacity of metastable water between 100K and 300K Molecular simulations have been used to study the heat capacity of metastable liquid water…
Elastic Compliance and Stiffness Matrix of the FCC Lennard-Jones Thin Films: Influence of Thickness and Temperature
J. Puibasset
The fcc Lennard-Jones crystal is used as a generic model of solid to study the elastic properties of thin films as a function of thickness and temperature. The Monte Carlo algorith…
Adsorption-Induced Deformation of a Nanoporous Material: Influence of the Fluid-Adsorbent Interaction and Surface Freezing on the Pore-Load Modulus Measurement
J. Puibasset
Liquid adsorption in nanoporous materials induces their deformation due to strong capillary forces. The linear relationship between the liquid pressure and the solid strain (pore-l…

Phase II of SIMPLE (Superheated Instrument for Massive ParticLe Experiments) searched for astroparticle dark matter using superheated liquid CClF droplet detectors. Eac…
Influence of system size on the properties of a fluid adsorbed in a nanopore: Physical manifestations and methodological consequences
Joël Puibasset, Edouard Kierlik, Gilles Tarjus
We consider the theoretical description of a fluid adsorbed in a nanopore. Hysteresis and discontinuities in the isotherms in general hampers the determination of equilibrium therm…
