In-plane structure of the electric double layer in the primitive model using classical density functional theory
Peter Cats, Andreas Härtel
The electric double layer (EDL) has a pivotal role in screening charges on surfaces as in supercapacitor electrodes or colloidal and polymer solutions. Its structure is determined…
Anomalous Underscreening in the Restricted Primitive Model
Andreas Härtel, Moritz Bültmann, Fabian Coupette
Underscreening is a collective term for charge correlations in electrolytes decaying slower than the Debye length. Anomalous underscreening refers to phenomenology that cannot be a…
Extension of the primitive model by hydration shells and its impact on the reversible heat production during the buildup of the electric double layer
Philipp Pelagejcev, Fabian Glatzel, Andreas Härtel
Recently the reversible heat production during the electric double layer (EDL) buildup in a sodium chloride solution was measured experimentally [Janssen et al., Phys. Rev. Lett. 1…
Anisotropy and memory during cage breaking events close to a wall
Matthias Kohl, Andreas Härtel, Michael Schmiedeberg
The slow dynamics in a glassy hard-sphere system is dominated by cage breaking events, i.e., rearrangements where a particle escapes from the cage formed by its neighboring particl…
Anisotropic pair correlations in binary and multicomponent hard-sphere mixtures in the vicinity of a hard wall: A combined density functional theory and simulation study
Andreas Härtel, Matthias Kohl, Michael Schmiedeberg
The fundamental measure approach to classical density functional theory has been shown to be a powerful tool to predict various thermodynamic properties of hard-sphere systems. We…
Fundamental measure theory for the electric double layer: implications for blue-energy harvesting and water desalination
Andreas Härtel, Mathijs Janssen, Sela Samin +1
Capacitive mixing (CAPMIX) and capacitive deionization (CDI) are promising candidates for harvesting clean, renewable energy and for the energy efficient production of potable wate…
Boosting capacitive blue-energy and desalination devices with waste heat
Mathijs Janssen, Andreas Härtel, René van Roij
We show that sustainably harvesting 'blue' energy from the spontaneous mixing process of fresh and salty water can be boosted by varying the water temperature during a capacitive m…
Differently Shaped Hard Body Colloids in Confinement: From passive to active particles
Henricus H. Wensink, Hartmut Löwen, Matthieu Marechal +5
We review recent progress in the theoretical description of anisotropic hard colloidal particles. The shapes considered range from rods and dumbbells to rounded cubes, polyhedra an…
Free energies, vacancy concentrations and density distribution anisotropies in hard--sphere crystals: A combined density functional and simulation study
M. Oettel, S. Goerig, A. Haertel +3
We perform a comparative study of the free energies and the density distributions in hard sphere crystals using Monte Carlo simulations and density functional theory (employing Fun…
