A minimal model of elastic instabilities in biological filament bundles (2022)
Journal Article
Panter, J., Kusumaatmaja, H., & Prior, C. (2022). A minimal model of elastic instabilities in biological filament bundles. Journal of the Royal Society. Interface, 19(194), Article 20220287. https://doi.org/10.1098/rsif.2022.0287

We present a model of a system of elastic fibres which exhibits complex, coupled, nonlinear deformations via a connecting elastic spring network. This model can capture physically observed deformations such as global buckling, pinching and internal c... Read More about A minimal model of elastic instabilities in biological filament bundles.

Encapsulated Nanodroplet Crystallization of Organic-Soluble Small Molecules (2020)
Journal Article

Small molecules can form crystalline solids, in which individual molecules pack together into ordered three-dimensional arrays. Once a suitable crystal is grown, the packing and atomic connectivity of the constituent molecules can be studied by X-ray...

Threaded Rings that Swim in Excitable Media (2019)
Journal Article
Cincotti, A., Maucher, F., Evans, D., Chapin, B. M., Horner, K., Bromley, E., …Sutcliffe, P. (2019). Threaded Rings that Swim in Excitable Media. Physical Review Letters, 123(25), Article 258102. https://doi.org/10.1103/physrevlett.123.258102

Cardiac tissue and the Belousov-Zhabotinsky reaction provide two notable examples of excitable media that support scroll waves, in which a filament core is the source of spiral waves of excitation. Here we consider a novel topological configuration i... Read More about Threaded Rings that Swim in Excitable Media.

Controlling Fragment Competition on Pathways to Addressable Self-Assembly (2018)
Journal Article
Madge, J., Bourne, D., & Miller, M. A. (2018). Controlling Fragment Competition on Pathways to Addressable Self-Assembly. Journal of Physical Chemistry B (Soft Condensed Matter and Biophysical Chemistry), 122(42), 9815-9825. https://doi.org/10.1021/acs.jpcb.8b08096

Addressable self-assembly is the formation of a target structure from a set of unique molecular or colloidal building-blocks, each of which occupies a defined location in the target. The requirement that each type of building-block appears exactly on... Read More about Controlling Fragment Competition on Pathways to Addressable Self-Assembly.

Knot theory in modern chemistry (2016)
Journal Article
Horner, K. E., Miller, M. A., Steed, J. W., & Sutcliffe, P. M. (2016). Knot theory in modern chemistry. Chemical Society Reviews, 45(23), 6432-6448. https://doi.org/10.1039/c6cs00448b

Knot theory is a branch of pure mathematics, but it is increasingly being applied in a variety of sciences. Knots appear in chemistry, not only in synthetic molecular design, but also in an array of materials and media, including some not traditional... Read More about Knot theory in modern chemistry.

Elasticity dominated surface segregation of small molecules in polymer mixtures (2016)
Journal Article

We study the phenomenon of migration of the small molecular weight component of a binary polymer mixture to the free surface using mean field and self-consistent field theories. By proposing a free energy functional that incorporates polymer-matrix e... Read More about Elasticity dominated surface segregation of small molecules in polymer mixtures.

Delayed self-regulation and time-dependent chemical drive leads to novel states in epigenetic landscapes (2014)
Journal Article
Mitra, M., Taylor, P., Hutchison, C., McLeish, T., & Chakrabarti, B. (2014). Delayed self-regulation and time-dependent chemical drive leads to novel states in epigenetic landscapes. Journal of the Royal Society. Interface, 11(100), https://doi.org/10.1098/rsif.2014.0706

The epigenetic pathway of a cell as it differentiates from a stem cell state to a mature lineage-committed one has been historically understood in terms of Waddington's landscape, consisting of hills and valleys. The smooth top and valley-strewn bott... Read More about Delayed self-regulation and time-dependent chemical drive leads to novel states in epigenetic landscapes.

Monte Carlo Simulation of Geminate Pair Recombination Dynamics in Organic Photovoltaic Devices: Multi-Exponential, Field-Dependent Kinetics and Its Interpretation (2014)
