Chemical Vapour Deposition (CVD)

Kwang Leong Choy [DPhil (oxon), DSc, FIMMM, FRSC, CSi] is a professor of Materials Discovery and Director of the UCL Institute for Materials Discovery. She has pioneered the novel electrostatic spray-assisted vapour deposition (a variant of CVD) technology, which is not only low cost, ecofriendly, and energy efficient, but also enhances coated product performance. Her contributions to the understanding of interactions between gaseous chemical species and solid substrates enables the control of the nucleation and growth of materials with a well-controlled structure and composition at the molecular level. This has led to the creation of high-performance ceramic films and new nanocomposite coatings. This technology has been successfully translated from the laboratory to industry, with the creation of two spin-off companies, and has led to Professor Choy being awarded the Grunfeld Memorial Award and Medal by the Institute of Materials for recognition of her professional contributions which have had significant impact on engineering applications.   Many of her advanced nanostructured ceramic coating materials and CVD-based coating technologies have led to significant impact and been exploited for industrial applications. These include ceramiccoated fibre-reinforced composites, ceramic thermal barrier coatings, superthin film inorganic transparent conducting films for displays and thin film solar cells, as well as multifunctional nanocomposite coatings for tribological applications. She has authored over 250 peer-reviewed publications, including 5 books and 20 patents in nanomaterials, superthin/thin/thick films, and nanocomposite coatings for structural, functional, and biomedical applications. She has also contributed to the Handbook of Nanostructured Materials and Nanotechnology by Academic Press (2000), which received an award of excellence from the Association of American Publishers. She has given over 150 plenary/keynote papers/ invited lectures. She is a fellow of the Institute for Materials, Minerals and Mining (IOM3), a fellow of the Royal Society of Chemistry (FRSC), and is a Chartered Scientist, CSci. She has been awarded Guest Professorships at the University of Uppsala (2001/03), Ningbo Institute of Materials Technology and Engineering (NIMTE, 2010/2012), and the Chinese Academy of Sciences (CAS) Visiting Professorship for Senior International Scientist (2011/2013). She also participates in developing the European materials research roadmap and represents the UK in the Materials Experts Task Forces for High Level Group of EU Member States and H2020 Associated Countries on Nanosciences, Nanotechnologies (2016/17).   Professor Choy’s work has led to her participation in numerous large research programmes. These include EU, EPSRC, and government flagship grants, as well as research contracts and collaboration to develop new engineering products with particular characteristics with industrial companies such as Rolls Royce, Aero Engine Control, EADS, PVi, QinetiQ, DSTL, BG/Advantica, and IMPT. She has been the international expert reviewer for Ontario Research Fund, Hong Kong Productivity Council, and Greek Ministry of Education/European Commission. She has been awarded Guest Professorships at the University of Uppsala (2001/03), Ningbo Institute of Materials Technology and Engineering (NIMTE, 2010/2012), and Chinese Academy of Sciences (CAS) Visiting Professorship for Senior International Scientist (2011/2013).
