2D foams above the jamming transition: Deformation matters
(2017)Jammed soft matter systems are often modelled as dense packings of overlapping soft spheres, thus ignoring particle deformation. For 2D (and 3D) soft disks packings, close to the critical packing fraction ϕc, this results ... -
Ab initio transport across bismuth selenide surface barriers.
(2014)We investigate the effect of potential barriers in the form of step edges on the scattering properties of Bi2Se3(111) topological surface states by means of large-scale ab initio transport simulations. Our results demonstrate ... -
Analysis of the foam-forming of non-woven lightweight fibrous materials using X-ray tomography
(2021)Foam-forming has in the past predominantly been used to create two-dimensional sheet-like fibrous materials. Allowing the foam to drain freely and decay under gravity, rather than applying a vacuum to remove it rapidly, ... -
Buckling of a linear chain of hard spheres in a harmonic confining potential: Numerical and analytical results for low and high compression
(2020)We extend a previous analysis of the buckling properties of a linear chain of hard spheres between hard walls under transverse harmonic confinement. Two regimes are distinguished—low compression, for which the entire chain ... -
Buckling of a tilted line of confined hard spheres
(2022)A linear chain of hard spheres confined in a transverse harmonic potential is unstable and buckles, if tilted beyond some critical angle. We examine this symmetry breaking using a computational model that was previously ... -
A continuum description of the buckling of a line of spheres in a transverse harmonic confining potential
(2023)A line of contacting hard spheres, placed in a transverse confining potential, buckles under compression or when tilted away from the horizontal, once a critical tilt angle is exceeded. This interesting nonlinear problem ... -
Equilibrium shape of a bubble in a liquid-filled horizontal capillary
(2024)Bubbles in liquid-filled capillaries feature in many practical applications. Here we describe the equilibrium shape of a bubble in a horizontal capillary of circular cross section, as computed numerically using energy ... -
Equilibrium states of confined ions in two dimensions
(2023)Ions that are trapped in two dimensions and are subject to a harmonic confining potential have widely varying stationary states that exhibit various asymptotic forms and bifurcations. We present a ‘birds-eye’ view of these ... -

Implementation of Morse-Witten theory for a polydisperse wet 2D foam simulation
(Taylor & Francis, 2019-06)The Morse–Witten theory provides a formulation for the inter-bubble forces and corresponding deformations in a liquid foam, accurate in the limit of high liquid fraction. Here we show how the theory may be applied in ... -
Microscopic mechanism of electron transfer through the hydrogen bonds between carboxylated alkanethiol molecules connected to gold electrodes
(2014)The atomic structure and the electron transfer properties of hydrogen bonds formed between two carboxylated alkanethiol molecules connected to gold electrodes are investigated by employing the non-equilibrium Green's ... -
Microscopic origin of the 1.3 G0 conductance observed in oxygen-doped silver quantum point contacts
(2014)Besides the peak at one conductance quantum, G0, two additional features at ∼0.4 G0 and ∼1.3 G0 have been observed in the conductance histograms of silver quantum point contacts at room temperature in ambient conditions. ... -
Molecular dynamics investigation of carbon nanotube junctions in non-aqueoussolutions
(2014)The properties of liquids in a confined environment are known to differ from those in the bulk. Extending this knowledge to geometries defined by two metallic layers in contact with the ends of a carbon nanotube is important ... -
Packing soft spheres: experimental demonstrations with hydrogels
(2023)We describe a number of different experimental set-ups that use hydrogel spheres to demonstrate dense packings of deformable spheres in various geometries. The arrangements are similar to those of bubbles in foams, ...
