Numerical Investigation of the Settling Behavior of Non-Spherical Particles - Application of Homogenized Lattice Boltzmann Methods

, 2021
Zur Verbesserung von Trennprozessen bezüglich der Effizienz und Selektivität ist es notwendig, das Wissen über das Verhalten von Partikeln in Strömungen zu erweitern. Dies ist insbesondere der Fall für Partikel im Größenbereich um $1\textrm{µm}$, da hier weder die Diffusion, noch Trägheitseffekte die Dynamik dominant bestimmen.

Engineered Protein‐Based Ionic Conductors for Sustainable Energy Storage Applications

Advanced Materials, EarlyView.
Rational incorporation of charged residues into an engineered, self‐assembling protein scaffold yields solid‐state protein films with outstanding ionic conductivity. Salt‐doping further enhances conductivity, an effect amplified in the engineered variants. These properties enable the material integration into an efficient supercapacitor.

Homogenized lattice Boltzmann methods for fluid flow through porous media – Part I: Kinetic model derivation

ESAIM: Mathematical Modelling and Numerical Analysis
In this series of studies, we establish homogenized lattice Boltzmann methods (HLBM) for simulating fluid flow through porous media. Our contributions in part I are twofold. First, we assemble the targeted partial differential equation system by formally unifying the governing equations for non-stationary fluid flow in porous media.

Nucleation Kinetics Reveals a Distinct Biological Function Space of Biomolecular Condensates

Advanced Science, EarlyView.
This study utilizes microfluidics to quantify the nucleation rates of dense liquid phases within dilute solutions and of the reverse process, in which dilute voids nucleate inside condensates. The interfacial tension is identified as the key determinant of both processes.

Hydrodynamic forces on steady and oscillating porous particles

, 2012
We derive new analytical results for the hydrodynamic force exerted on a sinusoidally oscillating porous shell and a sphere of uniform density in the Stokes limit. The coupling between the spherical particle and the solvent is done using the Debye-Bueche-

Fabrication of Composite Cathode for All‐Solid‐State Sodium Batteries

Advanced Energy Materials, EarlyView.
The design of composite cathodes for all‐solid‐state sodium batteries must address three critical challenges—interfacial side reactions, interfacial delamination, and highly tortuous transport pathways. This work outlines structural and interfacial strategies to optimize ion transport and mechanical stability, enabling durable, and high‐performance ...

Structural Complexity and Phonon Physics in 2D Arsenenes

, 2017
In the quest for stable 2D arsenic phases, four different structures have been recently claimed to be stable. We show that, due to phonon contributions, the relative stability of those structures differs from previous reports and depends crucially on ...

Flow-parametric regulation of shear-driven phase separation in two and three dimensions [PDF]

, 2014
The Cahn-Hilliard equation with an externally-prescribed chaotic shear flow is studied in two and three dimensions. The main goal is to compare and contrast the phase separation in two and three dimensions, using high-resolution numerical simulation as ...

Diffusion of Mn interstitials in (Ga,Mn)As epitaxial layers

, 2011
Magnetic properties of thin (Ga,Mn)As layers improve during annealing by out-diffusion of interstitial Mn ions to a free surface. Out-diffused Mn atoms participate in the growth of a Mn-rich surface layer and a saturation of this layer causes an ...
