Hard coatings are frequently applied to equipment operating in harsh environments. Often such coatings are highly brittle and so fragile under stress, especially at high temperatures or in corrosive environments. Premature failure can affect safety and lead to negative economic and environmental consequences. The objective of this project is to combine bioinspired microstructural design with an emerging alloying concept to produce a breakthrough in the development of engineering coatings; for example, overcoming the long standing trade-off between hardness and toughness. Such an innovative coating is expected to be highly durable in extreme conditions, and in so doing will help transform manufacturing, mining and desalination industries.Read moreRead less

Beyond the diffraction limit: sub-diffraction T-ray biochip sensing using planar metamaterials. T-rays are able to detect small changes in molecular structure and different isomeric and intermolecular configurations. With a comparatively long wavelength (0.3 mm at 1 THz), diffraction limits its use for imaging small biosamples. A method for achieving sub-diffraction sensing, required for biochips, is to adopt near-field techniques. However, due to the small biosample masses, there is a critical ....Beyond the diffraction limit: sub-diffraction T-ray biochip sensing using planar metamaterials. T-rays are able to detect small changes in molecular structure and different isomeric and intermolecular configurations. With a comparatively long wavelength (0.3 mm at 1 THz), diffraction limits its use for imaging small biosamples. A method for achieving sub-diffraction sensing, required for biochips, is to adopt near-field techniques. However, due to the small biosample masses, there is a critical need to enhance the response. This project will investigate a planar metamaterial thin-film T-ray sensor, for a new leap in non-invasive biochip sensing. This outcome will build downstream IP for rapid screening of DNA and proteins for healthcare. The project will also elucidate the science of T-ray interaction with biomaterials at small scales.Read moreRead less
