Cocrystallisation of butanoic acid (BA), pentanoic acid (PA), and eicosanoic acid (EA) with 4,4’-azopyridine (azp) and trans-1,2-bis(4-pyridyl)ethylene (bpe) results in 2:1 lamellar cocrystals. All cocrystals display the OH···Npyridyl seven-membered... Read More about Anisotropic thermal expansion effects in layered n-Alkyl carboxylic acid – bipyridyl cocrystals.

Bubble rise in molten glasses and silicate melts during heating and cooling cycles (2022)
Journal Article

The Hadamard–Rybczynski equation describes the steady-state buoyant rise velocity of an unconfined spherical bubble in a viscous liquid. This solution has been experimentally validated for the case where the liquid viscosity is held constant. Here, w...

Structured ternary fluids as nanocrystal incubators for enhanced crystallization control (2022)
Journal Article

In crystallization from solution, a ubiquitous process in both industry and the natural world, nucleation is usually the rate-determining step, followed by faster crystal growth. Consequently, crystals typically exist in the nm-size range for such li... Read More about Structured ternary fluids as nanocrystal incubators for enhanced crystallization control.

In-conduit capture of sub-micron volcanic ash particles via turbophoresis and sintering (2022)
Journal Article

Ash emission in explosive silicic eruptions can have widespread impacts for human health, agriculture, infrastructure, and aviation. Estimates of the total grainsize distribution (TGSD) generated during explosive magma fragmentation underpins eruptio...

Hydroxide films on mica form charge-stabilized microphases that circumvent nucleation barriers (2022)
Journal Article

Crystal nucleation is facilitated by transient, nanoscale fluctuations that are extraordinarily difficult to observe. Here, we use high-speed atomic force microscopy to directly observe the growth of an aluminum hydroxide film from an aqueous solutio...

The initial phase of the 2021 Cumbre Vieja ridge eruption (Canary Islands): Products and dynamics controlling edifice growth and collapse (2022)
Journal Article

Tajogaite cone in the Cumbre Vieja ridge (La Palma, Canary Islands) erupted between 19 September and 13 December 2021. The tephra and lava sourced from the newly formed fissure rapidly built a pyroclastic cone. During the early days of eruption and a...

The secrets to successful entrepreneurship: How occupational experience shapes the creation and performance of start-ups (2022)
Journal Article

Purpose Previous experience is a critical factor affecting entrepreneurial activities; however, it has not been fully studied in the existing literature. This study attempts to comprehensively reveal the routes and mechanisms of occupational experien...

Spontaneous phase separation of ternary fluid mixtures (2022)
Journal Article

We computationally study the spontaneous phase separation of ternary fluid mixtures using the lattice Boltzmann method both when all the surface tensions are equal and when they have different values. To rationalise the phase diagram of possible phas... Read More about Spontaneous phase separation of ternary fluid mixtures.

Encapsulated bacteria deform lipid vesicles into flagellated swimmers (2022)
Journal Article

We study a synthetic system of motile Escherichia coli bacteria encapsulated inside giant lipid vesicles. Forces exerted by the bacteria on the inner side of the membrane are sufficient to extrude membrane tubes filled with one or several bacteria. W...

Aging in a mean field elastoplastic model of amorphous solids (2020)
Journal Article

We construct a mean-field elastoplastic description of the dynamics of amorphous solids under arbitrary time-dependent perturbations, building on the work of Lin and Wyart [Phys. Rev. X 6, 011005 (2016)] for steady shear. Local stresses are driven by... Read More about Aging in a mean field elastoplastic model of amorphous solids.

Development, structure, and behavior of a perched lava channel at Kīlauea Volcano, Hawaiʻi, during 2007 (2022)
Journal Article

Channelized lava flows are commonly produced during the early stages of basaltic eruptions. These channels usually maintain their morphology until the eruption ends or discharge is diverted. In some instances, narrower channels can roof over, develop... Read More about Development, structure, and behavior of a perched lava channel at Kīlauea Volcano, Hawaiʻi, during 2007.

An advanced, comprehensive thermochemical equilibrium model of a downdraft biomass gasifier (2022)
Journal Article

A stoichiometric model is formulated for predicting the syngas yield from the reduction zone of a downdraft biomass gasifier. It incorporates the thermodynamic equilibrium of the global gasification reaction, predicts the concentration of the minor g...

Power fluctuations in sheared amorphous materials: A minimal model (2022)
Journal Article

The importance of mesoscale fluctuations in flowing amorphous materials is widely accepted, without a clear understanding of their role. We propose a mean-field elastoplastic model that admits both stress and strain-rate fluctuations, and investigate...

Dendritic crystallization in hydrous basaltic magmas controls magma mobility within the Earth’s crust (2022)
Journal Article

The majority of basaltic magmas stall in the Earth’s crust as a result of the rheological evolution caused by crystallization during transport. However, the relationships between crystallinity, rheology and eruptibility remain uncertain because it is...

Interparticle and Brownian forces controlling particle aggregation and rheology of silicate melts containing platinum-group element particles (2022)
Journal Article

We study the rheology of silicate melts containing platinum-group element (PGE) particles. They exhibit a shear-thinning behaviour, an intense aggregation tendency, and an anomalously high apparent viscosity in the low shear rate limit, even at very...
