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…
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,…
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…
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…
Network-like propagation of cell-level stress in random foams
Myfanwy E. Evans, Andrew M. Kraynik, Douglas A. Reinelt +2
Quasistatic simple shearing flow of random monodisperse soap froth is investigated by analyzing Surface Evolver simulations of spatially periodic foams. Elastic-plastic behavior is…
Shortcomings of the Bond Orientational Order Parameters for the Analysis of Disordered Particulate Matter
Walter Mickel, Sebastian C. Kapfer, Gerd E. Schröder-Turk +1
Local structure characterization with the bond-orientational order parameters q4, q6, ... introduced by Steinhardt et al. has become a standard tool in condensed matter physics, wi…
Jammed Spheres: Minkowski Tensors Reveal Onset of Local Crystallinity
Sebastian C. Kapfer, Walter Mickel, Klaus Mecke +1
The local structure of disordered jammed packings of monodisperse spheres without friction, generated by the Lubachevsky-Stillinger algorithm, is studied for packing fractions abov…
