Two-stage crystallization of charged colloids at low supersaturations
Kai Kratzer, Axel Arnold
We report simulations on the homogeneous liquid-fcc nucleation of charged colloids for both low and high contact energy values. As a precursor for crystal formation, we observe inc…
Modelling nano-particle agglomeration using local interactions
Gizem Inci, Axel Arnold, Andreas Kronenburg +1
Nano-particle agglomeration plays an important role in processes such as spray drying and particle flame synthesis. These processes have in common that nano-particles collide at lo…
Kinetic and ion pairing contributions in the dielectric spectra of electrolyte aqueous solutions
Marcello Sega, Sofia Kantorovich, Christian Holm +1
Understanding dielectric spectra can reveal important information about the dynamics of solvents and solutes from the dipolar relaxation times down to electronic ones. In the late…
Kinetic dielectric decrement revisited: phenomenology of finite ion concentrations
Marcello Sega, Sofia Kantorovich, Axel Arnold
With the help of a recently developed non-equilibrium approach, we investigate the ionic strength dependence of the Hubbard--Onsager dielectric decrement. We compute the depolariza…
Hydrodynamic Correlations slow down Crystallization of Soft Colloids
Dominic Roehm, Stefan Kesselheim, Axel Arnold
Crystallization is often assumed to be a quasi-static process that is unaffected by details of particle transport other than the bulk diffusion coefficient. Therefore colloidal sus…
Automatic, optimized interface placement in forward flux sampling simulations
Kai Kratzer, Axel Arnold, Rosalind J. Allen
Forward flux sampling (FFS) provides a convenient and efficient way to simulate rare events in equilibrium or non-equilibrium systems. FFS ratchets the system from an initial state…
