Magma fragmentation in highly explosive basaltic eruptions induced by rapid crystallisation (2019)
Journal Article

Basaltic eruptions are the most common form of volcanism on Earth and planetary bodies. The low viscosity of basaltic magmas inhibits fragmentation, which favours effusive and lava-fountaining activity, yet highly explosive, hazardous basaltic erupti...

Edge fracture instability in sheared complex fluids: Onset criterion and possible mitigation strategy (2019)
Journal Article

We perform a detailed theoretical study of the edge fracture instability, which commonly destabilizes the fluid-air interface during strong shear flows of entangled polymeric fluids, leading to unreliable rheological measurements. By means of direct... Read More about Edge fracture instability in sheared complex fluids: Onset criterion and possible mitigation strategy.

Enhancing the Efficiency in a Dye-Sensitized Solar Cell Based on a Metal Oxide Nanocomposite Gel Polymer Electrolyte (2019)
Journal Article

In order to overcome the critical limitations of liquid electrolyte-based dye-sensitized solar cells, quasi-solid-state electrolytes have been explored as a means of addressing long-term device stability, albeit with comparatively low ionic conductiv...

Wetting boundaries for a ternary high-density-ratio lattice Boltzmann method (2019)
Journal Article

We extend a recently proposed ternary free-energy lattice Boltzmann model with high density contrast [Phys. Rev. Lett. 120, 234501 (2018)] by incorporating wetting boundaries at solid walls. The approaches are based on forcing and geometric schemes,... Read More about Wetting boundaries for a ternary high-density-ratio lattice Boltzmann method.

Linear instability of shear thinning pressure driven channel flow (2019)
Journal Article

We study theoretically pressure driven planar channel flow of shear thinning viscoelastic fluids. Combining linear stability analysis and full nonlinear simulation, we study the instability of an initially one-dimensional base state to the of two-dim...

Revealing Resonance Effects and Intramolecular Dipole Interactions in the Positional Isomers of Benzonitrile-Core Thermally Activated Delayed Fluorescence Materials (2019)
Journal Article

We report on the properties of the three positional isomers of (2,7-di-tert-butyl-9,9-dimethylacridin-10(9H)-yl)benzonitrile, which are found to have comparable donor steric environments and donor–acceptor dihedral angles. An unexpected intramolecula...

A general ink formulation of 2d crystals for wafer-scale inkjet printing (2020)
Journal Article

Recent advances in inkjet printing of two-dimensional (2D) crystals show great promise for next-generation printed electronics development. Printing nonuniformity, however, results in poor reproducibility in device performance and remains a major imp...

On the application of the Spiegler-Kedem model to forward osmosis (2019)
Journal Article

In Forward Osmosis the diffusion of the solute is counter to that of the solvent i.e. there is so-called “reverse salt diffusion”. Furthermore, the ratio of the two fluxes is generally taken to be a constant because of the assumption of ideal semi-pe...

Experimental observations of bubbling regimes at in-line multi-orifice bubblers (2019)
Journal Article

Bubble formation and bubbling regimes are well-characterized for the cases of single-orifice bubblers and industrial perforated plates. However, bubbling regimes from bubblers with multiple in-line orifices remain poorly described. Here, we investiga...

BFSP1 C-terminal domains released by post-translational processing events can alter significantly the calcium regulation of AQP0 water permeability (2019)
Journal Article

BFSP1 (beaded filament structural protein 1, filensin) is a cytoskeletal protein expressed in the eye lens. It binds AQP0 in vitro and its C-terminal sequences have been suggested to regulate the water channel activity of AQP0. A myristoylated fragme...
