Predictive identification of co-formers in co-amorphous systems (2020)
Journal Article

This work aims to understand the properties of co-formers that form co-amorphous pharmaceutical materials and to predict co-amorphous system formation. A partial least square – discriminant analysis (PLS-DA) was performed using known co-amorphous sys... Read More about Predictive identification of co-formers in co-amorphous systems.

Suppressing Dimer Formation by Increasing Conformational Freedom in Multi-Carbazole Thermally Activated Delayed Fluorescence Emitters (2020)
Journal Article

Ideal emitters for organic light-emitting diodes (OLEDs) are capable of efficiently harvesting non-emissive triplet states, have high colour stabilities, and possess high photoluminescence quantum yields (PLQYs). Maintaining colour stability and PLQY... Read More about Suppressing Dimer Formation by Increasing Conformational Freedom in Multi-Carbazole Thermally Activated Delayed Fluorescence Emitters.

Ductile and Brittle Yielding in Thermal and Athermal Amorphous Materials (2020)
Journal Article

We study theoretically the yielding of sheared amorphous materials as a function of increasing levels of initial sample annealing prior to shear, in three widely used constitutive models and three widely studied annealing protocols. In thermal system... Read More about Ductile and Brittle Yielding in Thermal and Athermal Amorphous Materials.

Control of Porphyrin Planarity and Aggregation by Covalent Capping: Bissilyloxy Porphyrin Silanes (2020)
Journal Article

Porphyrins are cornerstone functional materials that are useful in a wide variety of settings, ranging from molecular electronics to biology and medicine. Their applications are often hindered, however, by poor solubilities that result from their ext...

An experimentally validated numerical model for bubble growth in magma (2020)
Journal Article

Volcanic eruptions are driven by the growth of gas bubbles in magma. The timing and rate of bubble growth are important because they determine whether enough gas pressure can develop to fragment the melt. Bubbles grow in response to decompression and...

Explosive-effusive volcanic eruption transitions caused by sintering (2020)
Journal Article

Silicic volcanic activity has long been framed as either violently explosive or gently effusive. However, recent observations demonstrate that explosive and effusive behavior can occur simultaneously. Here, we propose that rhyolitic magma feeding sub...

Interplay of edge fracture and shear banding in complex fluids (2020)
Journal Article

We explore theoretically the interplay between shear banding and edge fracture in complex fluids by performing a detailed simulation study within two constitutive models: the Johnson–Segalman model and the Giesekus model. We consider separately param... Read More about Interplay of edge fracture and shear banding in complex fluids.

Lilypad aggregation: localised self-assembly and metal sequestration at a liquid-vapour interface (2020)
Journal Article

Spatially resolved soft materials, such as vesicles and microgels, have shown promise as selective adsorbents and microscale reaction vessels. However, spatiotemporal control of aggregation can be difficult to achieve. In this study, nickel(II) chlor...

Quantifying Microstructural Evolution in Moving Magma (2020)
Journal Article

Many of the grand challenges in volcanic and magmatic research are focused on understanding the dynamics of highly heterogeneous systems and the critical conditions that enable magmas to move or eruptions to initiate. From the formation and developme... Read More about Quantifying Microstructural Evolution in Moving Magma.

Chain-stretch relaxation from low-frequency Fourier transform rheology (2020)
Journal Article

Medium- or large-amplitude oscillatory shear (MAOS and LAOS, respectively) is sensitive to polymer chain structure, yet poses unsolved challenges for a priori structural characterization. We present a MAOS protocol applied to near-monodisperse linear... Read More about Chain-stretch relaxation from low-frequency Fourier transform rheology.

Permeability of polydisperse magma foam (2020)
Journal Article

Effective models for the evolution of magma permeability are key to understanding shallow magma ascent and eruption dynamics. Models are generally empirical constructs, commonly focused on monodisperse systems, and unable to cope with the foam limit... Read More about Permeability of polydisperse magma foam.

Minimizing polymorphic risk through cooperative computational and experimental exploration (2020)
Journal Article

We combine state-of-the-art computational crystal structure prediction (CSP) techniques with a wide range of experi-mental crystallization methods to understand and explore crystal structure in pharmaceuticals and minimize the risk of unanticipated l...

Axisymmetric flows on the torus geometry (2020)
Journal Article

We present a series of analytically solvable axisymmetric flows on the torus geometry. For the single-component flows, we describe the propagation of sound waves for perfect fluids, as well as the viscous damping of shear and longitudinal waves for i...

Three-dimensional data capture and analysis of intact eye lenses evidences emmetropia-associated changes and strain-dependent differences in epithelial cell organization (2020)
Journal Article

Organ and tissue development are highly coordinated processes; lens growth and functional integration into the eye (emmetropia) is a robust example. An epithelial monolayer covers the anterior hemisphere of the lens, and its organization is the key t...

Critical pressure asymmetry in the enclosed fluid diode (2020)
Journal Article

Joint physically and chemically pattered surfaces can provide efficient and passive manipulation of fluid flow. The ability of many of these surfaces to allow only unidirectional flow mean they are often referred to as fluid diodes. Synthetic analogu...

Enhanced lifetime of Organic Photovoltaic diodes achieved by blending with PMMA: Impact of morphology and Donor:Acceptor combination (2020)
Journal Article

In order to realise the potential of organic photovoltaic devices (OPVs) to provide cheap, scalable access to renewable energy, it is necessary to improve their lifetime and cost of encapsulation.

Phase transitions on non-uniformly curved surfaces: Coupling between phase and location (2020)
Journal Article

For particles confined to two dimensions, any curvature of the surface affects the structural, kinetic and thermodynamic properties of the system. If the curvature is non-uniform, an even richer range of behaviours can emerge. Using a combination of...
