Chang Li recently published a paper in which he investigates how the roughness and drag characteristics of biofilm may vary depending on the size of cuprous oxide particles used for coating the surface.

The piece of research, entitled An investigation into the effects of marine biofilm on the roughness and drag characteristics of surfaces coated with different sized cuprous oxide (Cu2O) particles’, was carried out by Chang Li, currently a doctoral candidate at Newcastle University and Doctoral Research Associate at Safinah Group, in conjunction with leading academics from Newcastle University, Strathclyde University and distinguished members of the R&D team of American Chemet Corporation.

The research paper reports results based on series of pressure drop measurements using flat plates coated with different sizes of Cu2O. Surface microstructure and roughness analyses were carried out every six weeks during a six-month immersion period using scanning electron microscopy and laser roughness surface profilometry. The data gathered was used for predicting added frictional drag caused by biofilm.
