Webinar on Microbially-induced Corrosion in Marine Infrastructure

Technical Seminar:
Microbially-induced Corrosion in Marine Infrastructure

Date, time & venue

8 February 2023 (Wednesday), 17:00-18:00, Seminar via Zoom Meeting

 

Organized by

HKIE Civil Division and The Hong Kong Polytechnic University

Programme Highlight

In marine environments, microbially induced corrosion (MIC) is a common phenomenon, caused by adhering to the interfaces (forming biofilms). MIC in marine environments represents a major issue in the lifespan of coastal infrastructure and metal materials. MIC can cause significant deterioration, shortening their lifespan, and causing considerable economic losses. Sulfate-reducing bacteria (SRB) have been established as the key bacterial communities in biofilms on material surfaces that can trigger MIC. Controlling SRB is an effective and efficient way to inhibit corrosion. This talk will start with a brief introduction to MIC in marine environments and currently used corrosion inhibition strategies with their advantages and limitations. Then, a recent study on using a novel bio-mineralization strategy for inhibiting corrosion and isolating materials from the corrosive medium for long-term protection. In the end, some discussions on the application of bio-mineralization in marine engineering will be provided.

Speakers

Dr. Xiaohao Sun is now a Research Assistant Professor at the Hong Kong Polytechnic University (PolyU) in the CEE department and a Member of the Jiangsu Province Comprehensive Transportation Society. Dr. Sun received his bachelor's degree in Highway and Bridge engineering in 2015 and his Ph.D. in geotechnical engineering in 2019 from Southeast University in Nanjing, China. Before joining PolyU, Dr. Sun had a position as Postdoctoral Researcher and then Research Assistant Professor at Southeast University. His main research interests mainly include Microbially induced carbonate precipitation (MICP) for concrete crack repair, Bio-cementation for dust and sandstorm control, Data-driven models in civil engineering, and Microbially induced corrosion in marine environments. He has published several SCI journal papers and has received various research awards, such as Top Cited Article and the Best Paper 2020-2021 in Land degradation and development, Geneva International Exhibition of Inventions. He also serves as a Youth Editor of the International Journal of Mining Science and Technology, The Innovation, and Biogeotechnics.
