The high throughput construction and analysis of bilayers of tetrahedra Open
A method for generating significant numbers of network configurations is developed appropriate to bilayers of systems such as SiO2, GeO2, and aluminosilicates. The presence of a mirror plane allows the bilayer structures to exactly map ont…

Structural effects of the insertion of large rings in two-dimensional networks Open
The structural effect of inserting large central rings into a two-dimensional network of three-coordinate nodes is investigated using a ring-growth Monte Carlo procedure. The size of the central ring is systematically varied, as is the inh…

Voronoi diagrams in quasi-2D hard sphere systems Open
Variants of the Voronoi construction, commonly applied to divide space, are analysed for quasi-two-dimensional hard sphere systems. Configurations are constructed from a polydisperse lognormal distribution of sphere radii, mimicking recent…

Simplified computational model for generating biological networks Open
We discuss a Monte Carlo method to simulate biological networks and compare to the underlying networks in experimental images.

Constructing bilayers with tuneable ring statistics and topologies Open
A computationally tractable method is developed and described to generate two-dimensional networks with the aim of producing configurations for thin films (bilayers) of SiO2 and related materials. The method developed allows ideal (defect-…

Controlling disorder in two-dimensional networks Open
Two-dimensional networks are constructed by reference to a distribution of ring sizes and a parameter (α) which controls the preferred nearest-neighbour spatial correlations, and allows network topologies to be varied in a systematic manne…

A Coarse-Grained Model for Free and Template-Bound Porphyrin Nanorings Open
Coarse-grained simulation models are developed to study both template-bound and free porphyrin nanoring systems. Key interactions are modeled with relatively simple (and physically motivated) energy functions which allow for relatively fac…
