    • Adsorption of an Ideal Gas on a Small Spherical Adsorbent 

      Strøm, Bjørn André; Bedeaux, Dick; Schnell, Sondre Kvalvåg (Peer reviewed; Journal article, 2021)
      The ideal gas model is an important and useful model in classical thermodynamics. This remains so for small systems. Molecules in a gas can be adsorbed on the surface of a sphere. Both the free gas molecules and the adsorbed ...

    • Gibbs ensemble Monte Carlo simulation of fluids in confinement: Relation between the differential and integral pressures 

      Erdős, Máté; Galteland, Olav; Bedeaux, Dick; Kjelstrup, Signe; Moultos, Othonas A.; Vlugt, Thijs J.H. (Peer reviewed; Journal article, 2020)
      The accurate description of the behavior of fluids in nanoporous materials is of great importance for numerous industrial applications. Recently, a new approach was reported to calculate the pressure of nanoconfined fluids. ...

    • Large Area Patterning of Highly Reproducible and Sensitive SERS Sensors Based on 10-nm Annular Gap Arrays 

      Luo, Sihai; Mancini, Andrea; Lian, Enkui; Xu, Wenqi; Berté, Rodrigo; Li, Yi (Peer reviewed; Journal article, 2022)
      Applicable surface-enhanced Raman scattering (SERS) active substrates typically require low-cost patterning methodology, high reproducibility, and a high enhancement factor (EF) over a large area. However, the lack of ...

    • A Legendre–Fenchel Transform for Molecular Stretching Energies 

      Bering, Eivind; Bedeaux, Dick; Kjelstrup, Signe; de Wijn, Astrid S.; Latella, Ivan; Rubi, Miguel (Peer reviewed; Journal article, 2020)
      Single-molecular polymers can be used to analyze to what extent thermodynamics applies when the size of the system is drastically reduced. We have recently verified using molecular-dynamics simulations that isometric and ...

    • Nanothermodynamic Description and Molecular Simulation of a Single-Phase Fluid in a Slit Pore 

      Galteland, Olav; Bedeaux, Dick; Kjelstrup, Signe (Peer reviewed; Journal article, 2021)
      We have described for the first time the thermodynamic state of a highly confined single-phase and single-component fluid in a slit pore using Hill’s thermodynamics of small systems. Hill’s theory has been named ...

    • Two-Phase Equilibrium Conditions in Nanopores 

      Rauter, Michael Tobias; Galteland, Olav; Erdos, Mate; Moultos, Othonas A.; Vlugt, Thijs J.H.; Schnell, Sondre Kvalvåg; Bedeaux, Dick; Kjelstrup, Signe (Peer reviewed; Journal article, 2020)
      It is known that thermodynamic properties of a system change upon confinement. To know how, is important for modelling of porous media. We propose to use Hill’s systematic thermodynamic analysis of confined systems to ...

    • When Thermodynamic Properties of Adsorbed Films Depend on Size: Fundamental Theory and Case Study 

      Strøm, Bjørn André; He, Jianying; Bedeaux, Dick; Kjelstrup, Signe (Peer reviewed; Journal article, 2020)
      Small system properties are known to depend on geometric variables in ways that are insignificant for macroscopic systems. Small system considerations are therefore usually added to the conventional description as needed. ...
