Journal Article

We expose significant changes in emission color of carbazole-based thermally activated delayed fluorescence (TADF) emitters that arise through the presence of persistent dimer states in thin films and organic light-emitting diodes(OLEDs).

Regioselective Functionalization of 7‐Azaindole by Controlled Annular Isomerism: The Directed Metalation‐Group Dance (2019)
Journal Article

The regioselective functionalization of 7‐azaindole by controlled annular directed metalation group isomerism is reported. The N‐7 carbamoyl azaindoles 2a–b undergo regioselective metalation and electrophile quench to furnish C‐6 substituted derivati...

Drying of ethanol/water droplets containing silica nanoparticles (2019)
Journal Article

The evaporation of colloidal drop on a substrate with a pinned contact line usually results in a ring stain (the so-called coffee-ring effect). In this paper, we present an investigation of the evaporation of sessile picoliter droplets of binary solv... Read More about Drying of ethanol/water droplets containing silica nanoparticles.

The ‘allosteron’ model for entropic allostery of self-assembly (2018)
Journal Article

Using the simple ‘allosteron’ model, we show that it is possible, in principle, to elicit pathways by which fluctuation allostery affects self-assembly of protein complexes. We treat the cases of (i) protein fibrils and nucleation, (ii) n-mer protein... Read More about The ‘allosteron’ model for entropic allostery of self-assembly.

The Effect of Ageing on the Structure and Properties of Model Liquid Infused Surfaces (2020)
Journal Article

Liquid infused surfaces (LIS) exhibit unique properties that make them ideal candidates for a wide range of applications, from anti-fouling and anti-icing coatings to self-healing surfaces and controlled wetting. However, when exposed to realistic en... Read More about The Effect of Ageing on the Structure and Properties of Model Liquid Infused Surfaces.

Braiding, branching and chiral amplification of nanofibres in supramolecular gels (2019)
Journal Article

Helical nanofibres play key roles in many biological processes. Entanglements between helices can aid gelation by producing thick, interconnected fibres, but the details of this process are poorly understood. Here, we describe the assembly of an achi...

Fracture healing and strength recovery in magmatic liquids (2019)
Journal Article

Cycles of fracture and healing in magma are important controls on outgassing time scales and repetitive seismicity at silicic volcanoes. Here, we experimentally drove silicate melts (at 109–1011 Pa·s) to tensile failure, measuring the strength during... Read More about Fracture healing and strength recovery in magmatic liquids.

Experimental constraints on the textures and origin of obsidian pyroclasts (2019)
Journal Article

Obsidian pyroclasts are commonly preserved in the fall deposits of explosive silicic eruptions. Recent work has suggested that they form by sintering of ash particles on the conduit walls above the fragmentation depth and are subsequently torn out an...

Long-lived ionic nano-domains can modulate the stiffness of soft interfaces (2019)
Journal Article

Metal ions underpin countless processes at bio-interfaces, including maintaining electroneutrality, modifying mechanical properties and driving bioenergetic activity. These processes are typically described by ions behaving as independently diffusing... Read More about Long-lived ionic nano-domains can modulate the stiffness of soft interfaces.

Cataractogenic load – a concept to study the contribution of ionizing radiation to accelerated aging in the eye lens (2019)
Journal Article

Ionizing radiation (IR) damages DNA and other macromolecules, including proteins and lipids. Most cell types can repair DNA damage and cycle continuously their macromolecules as a mechanism to remove defective proteins and lipids. In those cells that...

Self-assembly of small molecules at hydrophobic interfaces using group effect (2020)
Journal Article

Although common in nature, the self-assembly of small molecules at sold-liquid interfaces is difficult to control in artificial systems. The high mobility of dissolved small molecules limits their residence at the interface, typically restricting the...
