Sonomaglev: Combining acoustic and diamagnetic levitation (2023)
Journal Article

Acoustic levitation and diamagnetic levitation are experimental methods that enable the contact-free study of both liquid droplets and solid particles. Here, we combine both the techniques into a single system that takes advantage of the strengths of... Read More about Sonomaglev: Combining acoustic and diamagnetic levitation.

Analog cosmology with two-fluid systems in a strong gradient magnetic field (2019)
Journal Article

We propose an experiment combining fluid dynamics and strong magnetic field physics to simulate cosmological scenarios. Our proposed system consists of two immiscible, weakly magnetized fluids moved through a strong gradient magnetic field. The diama...

Magnetic Levitation Stabilized by Streaming Fluid Flows (2018)
Journal Article

We demonstrate that the ubiquitous laboratory magnetic stirrer provides a simple passive method of magnetic levitation, in which the so-called ‘flea’ levitates indefinitely. We study the onset of levitation and quantify the flea’s motion (a combinati... Read More about Magnetic Levitation Stabilized by Streaming Fluid Flows.

Centrifugally forced Rayleigh–Taylor instability (2018)
Journal Article

We consider the effect of high rotation rates on two liquid layers that initially form concentric cylinders, centred on the axis of rotation. The configuration may be thought of as a fluid-fluid centrifuge. There are two types of perturbation to the... Read More about Centrifugally forced Rayleigh–Taylor instability.

Shapes and fissility of highly charged and rapidly rotating levitated liquid drops (2017)
Journal Article

We use diamagnetic levitation to investigate the shapes and the stability of free electrically charged and spinning liquid drops of volume ∼1 ml. In addition to binary fission and Taylor cone-jet fission modes observed at low and high charge density,...

Magnetically Induced Rotating Rayleigh-Taylor Instability (2017)
Journal Article

Classical techniques for investigating the Rayleigh-Taylor instability include using compressed gasses, rocketry or linear electric motors to reverse the effective direction of gravity, and accelerate the lighter fluid toward the denser fluid. Other... Read More about Magnetically Induced Rotating Rayleigh-Taylor Instability.

Ice as a granular material (2016)
Conference Proceeding

Ice is a unique material, fundamental to vital processes on earth, in the atmosphere [1] and as planets and comets form [2]. In this work, we introduce two experiments investigating ice as a granular material, to provide snippets of insight into thos... Read More about Ice as a granular material.

Propulsion of a two-sphere swimmer (2015)
Journal Article

We describe experiments and simulations demonstrating the propulsion of a neutrally-buoyant swimmer that consists of a pair of spheres attached by a spring, immersed in a vibrating fluid. The vibration of the fluid induces relative motion of the sphe... Read More about Propulsion of a two-sphere swimmer.

The inhibition of the Rayleigh-Taylor instability by rotation (2015)
Journal Article

It is well-established that the Coriolis force that acts on fluid in a rotating system can act to stabilise otherwise unstable flows. Chandrasekhar considered theoretically the effect of the Coriolis force on the Rayleigh-Taylor instability, which oc... Read More about The inhibition of the Rayleigh-Taylor instability by rotation.

Artificial tektites: an experimental technique for capturing the shapes of spinning drops (2015)
Journal Article

Determining the shapes of a rotating liquid droplet bound by surface tension is an archetypal problem in the study of the equilibrium shapes of a spinning and charged droplet, a problem that unites models of the stability of the atomic nucleus with t...

Tuneable paramagnetic susceptibility and exciton g-factor in Mn-doped PbS colloidal nanocrystals (2014)
Journal Article

We report on PbS colloidal nanocrystals that combine within one structure solubility in physiological solvents with near-infrared photoluminescence, and magnetic and optical properties tuneable by the controlled incorporation of magnetic impurities (...

Mechanical vibrations of magnetically levitatedviscoelastic droplets (2014)
Journal Article

The mechanical vibrations of magnetically levitated droplets were investigated using a simple optical deflection technique. Droplets of water and a water-based solution of poly(acrylamide-co-acrylic acid) were levitated in the bore of a superconducti...

Meristematic cell proliferation and ribosome biogenesis are decoupled in diamagnetically levitated Arabidopsis seedlings (2013)
Journal Article

Background: Cell growth and cell proliferation are intimately linked in the presence of Earth’s gravity, but are decoupled under the microgravity conditions present in orbiting spacecraft. New technologies to simulate microgravity conditions for long...

Suboptimal evolutionary novel environments promote singular altered gravity responses of transcriptome during Drosophila metamorphosis (2013)
Journal Article

Background Previous experiments have shown that the reduced gravity aboard the International Space Station (ISS) causes important alterations in Drosophila gene expression. These changes were shown to be intimately linked to environmental space-fl...
