Smart Nanoparticles and Complex Light-Matter Interactions for Single-Molecule Sensing: Investigating Multifunctional Molecular Sensing and Metal-Atom Catalysis on Gold Nanoparticles at Single Molecule Level
(University of Exeter Physics and Astronomy, 17 February 2025)This thesis investigates the use of Whispering Gallery Mode (WGM) sensors for studying molecular interactions and catalytic processes at the single molecule level, focusing on engineered plasmonic nanoparticles. The research ... -
Unveiling the Photophysical and Triboelectric Properties of Novel 2D Materials
(University of Exeter Physics, 10 February 2025)Transformative innovations in nanotechnology have led to the integration of two-dimensional (2D) materials into a diverse range of technologies, including but not limited to photovoltaics, transistors, reinforced composites, ... -
BOWIE-ALIGN: JWST reveals hints of planetesimal accretion and complex sulphur chemistry in the atmosphere of the misaligned hot Jupiter WASP-15b
(Oxford University Press (OUP) / Royal Astronomical Society, 5 February 2025)We present a transmission spectrum of the misaligned hot Jupiter WASP-15b from 2.8–5.2 microns observed with JWST’s NIRSpec/G395H grating. Our high signal to noise data, which has negligible red noise, reveals significant ... -
Physical disturbance induces heart stop in mangrove killifish, Kryptolebias marmoratus embryos (dataset)
(University of Exeter, 29 January 2025)The mangrove killifish, Krypotlebias marmoratus, a self-fertilizing vertebrate, are frequently exposed to harsh environmental conditions. Diapause is one strategy they use to cope with this. Embryos are able to stop their ... -
Impacts of UV radiation from an AGN on planetary atmospheres and consequences for galactic habitability
(IOP Publishing, 18 February 2025)We present a study of the effects of ultraviolet (UV) emission from active galactic nuclei (AGN) on the atmospheric composition of planets and potential impact on life. It is expected that all supermassive black holes, ...
