Fluorescent carbon dot–molecular salt hydrogels (2015)
Journal Article

The incorporation of functionalised carbon nanodots within a novel low molecular weight salt hydrogel derived from 5-aminosalicylic acid is reported. The carbon dots result in markedly enhanced gelation properties, while inclusion within the hydropho... Read More about Fluorescent carbon dot–molecular salt hydrogels.

Shear Banding of Soft Glassy Materials in Large Amplitude Oscillatory Shear (2016)
Journal Article

We study shear banding in soft glassy materials subject to a large amplitude oscillatory shear flow (LAOS). By numerical simulations of the widely used soft glassy rheology model, supplemented by more general physical arguments, we demonstrate strong...

All the colours of the rainbow (2014)
Journal Article

Our perception of colour has always been a source of fascination, so it's little wonder that studies of the phenomenon date back hundreds of years. What, though, can modern scientists learn from medieval literature — and how do we go about it?

Tunable solid-state fluorescent materials for supramolecular encryption (2015)
Journal Article

Tunable solid-state fluorescent materials are ideal for applications in security printing technologies. A document possesses a high level of security if its encrypted information can be authenticated without being decoded, while also being resistant...

Relating Molecular Morphology to Charge Mobility in Semicrystalline Conjugated Polymers (2016)
Journal Article

The molecular-level origins of the effects of annealing temperature and molecular weight on hole mobility in P3HT are elucidated using coarse-grained molecular dynamics, quantum chemical calculations, and kinetic Monte Carlo charge-transport simulati...

Pharmaceutical Polymorph Control in a Drug-Mimetic Supramolecular Gel (2016)
Journal Article

We report the synthesis of a bis(urea) gelator designed to specifically mimic the chemical structure of the highly polymorphic drug substance ROY. Crystallization of ROY from toluene gels of this gelator results in the formation of the metastable red... Read More about Pharmaceutical Polymorph Control in a Drug-Mimetic Supramolecular Gel.

Anion Hydrogen Bonding from a ‘Revealed’ Urea Ligand (2016)
Journal Article

Hydrogen bonding from a urea group to hydrogen bond acceptor anions can adopt either R_2^1 (6) or R_2^2 (8) motifs depending on the proximity of hydrogen bond acceptor atoms. However, for the sterically bulky and weaker hydrogen bond acceptor triflat... Read More about Anion Hydrogen Bonding from a ‘Revealed’ Urea Ligand.

Clustering and phase behaviour of attractive active particles with hydrodynamics (2015)
Journal Article

We simulate clustering, phase separation and hexatic ordering in a monolayered suspension of active squirming disks subject to an attractive Lennard-Jones-like pairwise interaction potential, taking hydrodynamic interactions between the particles ful...

Design strategies for self-assembly of discrete targets (2015)
Journal Article

Both biological and artificial self-assembly processes can take place by a range of different schemes, from the successive addition of identical building blocks to hierarchical sequences of intermediates, all the way to the fully addressable limit in...

Thermally-nucleated self-assembly of water and alcohol into stable structures at hydrophobic interfaces (2016)
Journal Article

At the interface with solids, the mobility of liquid molecules tends to be reduced compared with bulk, often resulting in increased local order due to interactions with the surface of the solid. At room temperature, liquids such as water and methanol... Read More about Thermally-nucleated self-assembly of water and alcohol into stable structures at hydrophobic interfaces.

Correlation lengths in hydrodynamic models of active nematics (2016)
Journal Article

We examine the scaling with activity of the emergent length scales that control the nonequilibrium dynamics of an active nematic liquid crystal, using two popular hydrodynamic models that have been employed in previous studies. In both models we find... Read More about Correlation lengths in hydrodynamic models of active nematics.

The lens of the eye: exposures in the UK medical sector and mechanistic studies of radiation effects (2015)
Journal Article

The recommendation from the International Commission on Radiological Protection that the occupational equivalent dose limit for the lens of the eye should be reduced to 20 mSv year−1, averaged over 5 years with no year exceeding 50 mSv, has stimulate...

The role of protein-ligand contacts in allosteric regulation of the Escherichia coli Catabolite Activator Protein (2015)
Journal Article

Allostery is a fundamental process by which ligand binding to a protein alters its activity at a distant site. Both experimental and theoretical evidence demonstrate that allostery can be communicated through altered slow relaxation protein dynamics...

Numerical prediction of nonlinear rheology of branched polymer melts (2014)
Journal Article

In a recent short communication [Read, D. J. et al., Science 333, 1871 (2011)], we showed that a computational scheme can describe the nonlinear flow properties for a series of industrial low-density polyethylene (LDPE) resins starting from the molec...
