  • Spinning motile particles published in Materials Advances

Work with Dr Steve Ebbens in our Engineering faculty has recently been published in the RSC journal Materials Advances. This study was a fantastic way to make colloids that should enable enhanced mixing via tuning the rotation rate.

  • Coordinated Ras and Rac Activity Shapes Macropinocytic Cups and Enables Phagocytosis of Geometrically Diverse Bacteria

Forming cup-shaped protrusions allows cells to engulf extracellular fluid and particles by macropinocytosis and phagocytosis, respectively. This paper identifies a new regulator that differentially regulates small GTPases to generate cup shape. The paper proposes a model where this coordinates the shape and allows cells to engulf different bacterial shapes. Here is the paper link (open access).


  • X-ray nano-tomography of complete scales from the ultra-white beetles Lepidiota stigma and Cyphochilus

In this work we used X-ray holotomography to image single intact beetle scale cells mounted on the tip of a needle. In this paper we present full datasets for the ultra-white scales from the beetles Lepidiota stigma (L. stigma) and Cyphochilus. This will allow others to model these fascinating optical nanostructures. The paper can be accessed here (open access).

Various optical, x-ray and reconstructed images of the beetle scales. (a,b) The mounted Cyphochilus scale including a coordinate system for reference. (c,d) A mounted L. stigma scale. (e) An X-ray projection image of Cyphochilus scale. (f) A single slice through the xz plane of the assembled and aligned Cyphochilus matrix.

  • Profile retrieval of a buried periodic structure using spin echo grazing incidence neutron scattering

In this letter, we showed that it is possible to make large area measurements of periodic grating structures using SERGIS in a number of interesting scenarios. The SERGIS data can be analysed using a dynamical theory, which makes it possible to effectively retrieve the lateral profile of a commercial periodic diffraction grating.

This work was using the instrument OFFSPEC at the ISIS pulsed neutron source. We also got to work with some amazing people; Professor Roger Pynn (Indiana University), Dr Rob Dalgliesh (ISIS) and Professor Rana Ashkar (Virginia Tech.).

Scattering maps for the unpolarized scattering from the samples (a)–(c) and corresponding SERGIS signal (d)–(f). The three samples are uncoated aluminium grating (a) and (d), dPMMA buried grating (b) and (e), and thermally annealed dPMMA grating (c) and (f)
