Quo vadis biophotonics? Wearing serendipity and slow science as a badge of pride, and embracing biology
G. E. Schroeder-Turk
This article is a reflection on the themes of the Faraday Discussion meeting on "Biological and bio-inspired optics" held from 20 to 22 July 2020. It is a personal perspective on t…
Mixing properties of bi-disperse ellipsoid assemblies: Mean-field behaviour in a granular matter experiment
F. M. Schaller, H. Punzmann, G. E. Schröder-Turk +1
The structure and spatial statistical properties of amorphous ellipsoid assemblies have profound scientific and industrial significance in many systems, from cell assays to granula…
Composite material in the sea urchin Cidaris rugosa: ordered and disordered micron-scale bicontinuous geometries
Anna-Lee Jessop, Allan J. Millsteed, Jacob J. K. Kirkensgaard +3
The sponge-like biomineralised calcite materials found in echinoderm skeletons are of interest in terms of both structure formation and biological function. Despite their crystalli…
Low-temperature statistical mechanics of the QuanTizer problem: fast quenching and equilibrium cooling of the three-dimensional Voronoi Liquid
Tobias M. Hain, Michael A. Klatt, Gerd E. Schröder-Turk
The Quantizer problem is a tessellation optimisation problem where point configurations are identified such that the Voronoi cells minimise the second moment of the volume distribu…
Self-assembly and entropic effects in pear-shaped colloid systems: I. Shape sensitivity of bilayer phases in colloidal pear-shaped particle systems
Philipp W. A. Schönhöfer, Matthieu Marechal, Douglas J. Cleaver +1
The role of particle shape in self-assembly processes is a double-edged sword. On the one hand, particle shape and particle elongation are often considered the most fundamental det…
Self-assembly and entropic effects in pear-shaped colloid systems: II. Depletion attraction of pear-shaped particles in a hard sphere solvent
Philipp W. A. Schönhöfer, Matthieu Marechal, Douglas J. Cleaver +1
We consider depletion effects of a pear-shaped colloidal particle in a hard-sphere solvent, for two different model realisations of the pear-shaped colloidal particle. The two mode…
Patchy particles by self-assembly of star copolymers on a spherical substrate: Thomson solutions in a geometric problem with a color constraint
Tobias M. Hain, Gerd E. Schröder-Turk, Jacob J. K. Kirkensgaard
Confinement or geometric frustration is known to alter the structure of soft matter, including copolymeric melts, and can consequently be used to tune structure and properties. Her…
Geometric effects in random assemblies of ellipses
Jakov Lovrić, Sara Kaliman, Wolfram Barfuß +2
Assemblies of anisotropic particles commonly appear in studies of active many-body systems. However, in two dimensions, the geometric ramifications of the finite density of such ob…
Structural similarity between dry and wet sphere packings
Simon Weis, Gerd Schröder-Turk, Matthias Schröter
The mechanical properties of granular materials change significantly in the presence of a wetting liquid which creates capillary bridges between the particles. Here we demonstrate,…
Anisotropy in finite continuum percolation: Threshold estimation by Minkowski functionals
Michael A Klatt, Gerd E Schröder-Turk, Klaus Mecke
We examine the interplay between anisotropy and percolation, i.e., the spontaneous formation of a system spanning cluster in an anisotropic model. We simulate an extension of a ben…
Splitting of the universality class of anomalous transport in crowded media
Markus Spanner, Felix Höfling, Sebastian C. Kapfer +3
We investigate the emergence of subdiffusive transport by obstruction in continuum models for molecular crowding. While the underlying percolation transition for the accessible spa…
Non-universal Voronoi cell shapes in amorphous ellipsoid packings
Fabian M. Schaller, Sebastian C. Kapfer, James E. Hilton +8
In particulate systems with short-range interactions, such as granular matter or simple fluids, local structure plays a pivotal role in determining the macroscopic physical propert…
Appearance of the Single Gyroid Network Phase in Nuclear Pasta Matter
B. Schuetrumpf, M. A. Klatt, K. Iida +4
Nuclear matter under the conditions of a supernova explosion unfolds into a rich variety of spatially structured phases, called nuclear pasta. We investigate the role of periodic n…
Local origin of global contact numbers in frictional ellipsoid packings
Fabian M. Schaller, Max Neudecker, Mohammad Saadatfar +3
In particulate soft matter systems the average number of contacts of a particle is an important predictor of the mechanical properties of the system. Using X-ray tomography, we…
Percolation transition by random vertex splitting of diamond networks?
Susan Nachtrab, Matthias J. F. Hoffmann, Sebastian C. Kapfer +2
We propose a statistical model defined on the three-dimensional diamond network where the splitting of randomly selected nodes leads to a spatially disordered network, with decreas…
