  • Analytical solution to the Poisson–Nernst–Planck equations for the charging of a long electrolyte-filled slit pore 
    Aslyamov, Timur; Janssen, Mathijs Adriaan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    We study the charging dynamics of a long electrolyte-filled slit pore in response to a suddenly applied potential. In particular, we analytically solve the Poisson–Nernst–Planck (PNP) equations for a pore for which λD≪H≪L, ...
  • Crowding-Regulated Binding of Divalent Biomolecules 
    Skóra, Tomasz; Janssen, Mathijs Adriaan; Carlson, Andreas; Kondrat, Svyatoslav (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
  • Divalent ligand-monovalent molecule binding 
    Janssen, Mathijs Adriaan; Stenmark, Harald; Carlson, Andreas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Simultaneous binding of a divalent ligand to two identical monovalent molecules is a widespread phenomenon in biology and chemistry. Here, we describe how two such monovalent molecules B bind to a divalent ligand AA to ...
  • Dynamic density functional theory for the charging of electric double layer capacitors 
    Ma, Ke; Janssen, Mathijs Adriaan; Lian, Cheng; Van Roij, René (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)
    We consider the charging of a model capacitor comprised of two planar electrodes and an electrolyte. Upon switching on a voltage difference, electric double layers build up in this setup, which we characterize with a ...
  • ELECTRODE: An electrochemistry package for atomistic simulations 
    Ahrens-Iwers, Ludwig; Janssen, Mathijs Adriaan; Tee, Shern; Meißner, Robert (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Constant potential methods (CPMs) enable computationally efficient simulations of the solid–liquid interface at conducting electrodes in molecular dynamics. They have been successfully used, for example, to realistically ...
  • From Frequency Domain to Time Transient Methods for Halide Perovskite Solar Cells: The Connections of IMPS, IMVS, TPC, and TPV 
    Bisquert, Juan; Janssen, Mathijs Adriaan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The correlation of different methods of measurement can become an important tool to identify the dominant physical elements that govern the electronic and ionic dynamics in perovskite solar cells. The diverse phenomena ...
  • Locating the Frequency of Turnover in Thin-Film Diffusion Impedance 
    Janssen, Mathijs Adriaan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The impedance of diffusion is an important tool to investigate a wide variety of systems, including electrochemical devices such as Li-ion batteries, porous electrodes, and solar cells. The classical impedance model for ...
  • On the time-dependent electrolyte Seebeck effect 
    Sehnem, André Luiz; Janssen, Mathijs Adriaan (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)
    Single-ion Soret coefficients αi characterize the tendency of ions in an electrolyte solution to move in a thermal gradient. When these coefficients differ between cations and anions, an electric field can be generated. ...
  • Optimising nanoporous supercapacitors for heat-to-electricity conversion 
    Janssen, Mathijs Adriaan; Verkholyak, Taras; Kuzmak, Andrij; Kondrat, Svyatoslav (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)
    Innovative ways of harnessing sustainable energy are needed to meet the world’s ever-increasing energy demands. Supercapacitors may contribute, as they can convert waste heat to electricity through cyclic charging and ...
  • Reversible heat production during electric double layer buildup depends sensitively on the electrolyte and its reservoir 
    Glatzel, Fabian; Janssen, Mathijs Adriaan; Härtel, Andreas (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)
    Several modern technologies for energy storage and conversion are based on the screening of electric charge on the surface of porous electrodes by ions in an adjacent electrolyte. This so-called electric double layer (EDL) ...
  • Simulating the charging of cylindrical electrolyte-filled pores with the modified Poisson-Nernst-Planck equations 
    Yang, Jie; Janssen, Mathijs Adriaan; Lian, Cheng; Van Roij, René (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)
    Understanding how electrolyte-filled porous electrodes respond to an applied potential is important to many electrochemical technologies. Here, we consider a model supercapacitor of two blocking cylindrical pores on either ...
  • Transmission Line Circuit and Equation for an Electrolyte-Filled Pore of Finite Length 
    Janssen, Mathijs Adriaan (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)
    I discuss the strong link between the transmission line (TL) equation and the TL circuit model for the charging of an electrolyte-filled pore of finite length. In particular, I show how Robin and Neumann boundary conditions ...
