3D Maps of Mineral Composition and Hydroxyapatite Orientation in Fossil Bone Samples Obtained by X-ray Diffraction Computed Tomography
(Journal article; Peer reviewed, 2018)Whether hydroxyapatite (HA) orientation in fossilised bone samples can be non-destructively retrieved and used to determine the arrangement of the bone matrix and the location of muscle attachments (entheses), is a question ... -
A nano-silicate material with exceptional capacity for CO2 capture and storage at room temperature
(Journal article; Peer reviewed, 2018)In order to mitigate climate change driven by the observed high levels of carbon dioxide (CO2) in the atmosphere, many micro and nano-porous materials are being investigated for CO2 selectivity, capture and storage (CCS) ... -
Control of magnetic states and spin interactions in bilayer CrCl3 with strain and electric fields: an ab initio study
(Peer reviewed; Journal article, 2023)Using ab initio density functional theory, we demonstrated the possibility of controlling the magnetic ground-state properties of bilayer CrCl3 by means of mechanical strains and electric fields. In principle, we investigated ... -
Controlling spin supercurrents via nonequilibrium spin injection
(Journal article; Peer reviewed, 2019)We propose a mechanism whereby spin supercurrents can be manipulated in superconductor/ferromagnet proximity systems via nonequilibrium spin injection. We find that if a spin supercurrent exists in equilibrium, a nonequilibrium ... -
Controlling superconducting spin flow with spin-flip immunity using a single homogeneous ferromagnet
(Journal article; Peer reviewed, 2016)Spin transport via electrons is typically plagued by Joule heating and short decay lengths due to spin-flip scattering. It is known that dissipationless spin currents can arise when using conventional superconducting ... -
Degradation of insulin amyloid by antibiotic minocycline and formation of toxic intermediates
(Peer reviewed; Journal article, 2021)Insulin balls, localized insulin amyloids formed at subcutaneous insulin-injection sites in patients with diabetes, cause poor glycemic control owing to impairments in insulin absorption. Our previous study has shown that ... -
Describing synchronization and topological excitations in arrays of magnetic spin torque oscillators through the Kuramoto model
