It comes as a great news for both BU and academic staff that a major international patent has been granted by China National Intellectual Property Administration who have confirmed that it will record the grant of the patent right in the Patent Register, issue the patent certificate for invention, and announce the grant. The patent right shall take effect from the date of announcement, July 4, 2023.
This is a predictive and prognostic invention as a remote probing system to monitor corrosion of conductive or nonconductive coatings and subsurface degradation.
The EIS measurement is resistant to interference and has a high corrosion resolution which produces stable and reliable results. Protective properties of a coating can be learned from an impedance spectroscopy obtained via the measurement that reflects changes in the coating and at the interface of coating-substrate system.
Project lead Professor Zulfiqar Khan has congratulated their co-inventors Dr Mian Hammad Nazir and Dr Adil Saeed for their hard work, dedication and passion over the years. This is the result of years of collective work spanning over several research programmes, Professor Khan added.
This invention will enable, a diverse portfolio of industry sectors and applications in aerospace, automotive industry, shipyards, petrochemical, process, infrastructures, high value assets including Reinforced Concrete (RC) elements of marine structures such as piled jetties, marine installation, gas pipelines, motorways structures and mobile assets such as large vehicles, to monitor, predict and prognose a complex failure initiation and propagation mechanism in real time. This will result in significant cost savings, reducing downtime, enhancing reliability and service life.
