Light can generate an optical force to capture small objects. This requires intense light – a laser, which limits optical trapping in catalysis applications. This project aims to apply plasmonic nanoparticles with normal-intensity light to take advantage of plasmonic-generated optical forces for catalytic chemical synthesis. The optical trapping/releasing of small molecules is highly selective and responsive to molecule structure and so presents a great opportunity to radically alter chemical synthesis pathways, which will be illustrated with reactions on liquid-solid and gas-solid interfaces. This highly innovative strategy will be used to discover new nitrogen-based syntheses which are both fundamentally and industrially important.Read moreRead less

For decades astronomers have puzzled over the connection between the structure and evolution of galaxies and the role played by host environments. This project aims to resolve this problem by combining multi-wavelength observations, multi-component simulations, and pioneering data analysis using artificial intelligence.
