Spatial Statistics in Star Forming Regions: Testing the Limits of Randomness
(Oxford University Press (OUP) / Royal Astronomical Society, 11 May 2019)Observational studies of star formation reveal spatial distributions of Young Stellar Objects (YSOs) that are ‘snapshots’ of an ongoing star formation process. Using methods from spatial statistics it is possible to test ... -
Tiny grains shining bright in the gaps of Herbig Ae transitional discs
(Oxford University Press (OUP) / Royal Astronomical Society, 17 April 2019)This work presents a study of two Herbig Ae transitional discs, Oph IRS 48 and HD 169142; which both have reported rings in their dust density distributions. We use Keck-II/NIRC2 adaptive optics imaging observations in the ... -
Histopathological changes and antioxidant responses in common carp (Cyprinus carpio) exposed to copper nanoparticles
(Taylor & Francis, 15 May 2019)Despite the rapid increase of nanotechnology in a wide array of industrial sectors, the biosafety profile of nanomaterials remains undefined. The accelerated use of nanomaterials has increased the potential discharge of ... -
Direct monitoring of light mediated hyperthermia induced within mammalian tissues using surface enhanced spatially offset Raman spectroscopy (T-SESORS)
(Royal Society of Chemistry, 3 May 2019)Here we demonstrate light mediated heating of nanoparticles confined deep inside mammalian tissue, whilst directly monitoring their temperature non-invasively using a form of deep Raman spectroscopy, T-SESORS. One of the ... -
Gate Tunable Graphene-integrated Metasurface Modulator for Mid-Infrared Beam Steering (article)
(Optical Society of America, 6 May 2019)The ability to integrate graphene into metasurface devices has attracted enormous interest as a means of achieving dynamic electrical control of their electromagnetic response. In this manuscript, we experimentally demonstrate ...
