Post doctoral project: Glycerol-based fully green and renewable lubricants
It is reported that around 37 million metric tons lubricants are consumed every year, where about 98% of them are produced from petroleum. Glycerol (also named Glycerin) is a non-toxic and biodegradable compound which has great potential as a base fluid in environmentally friendly lubricants but is currently treated as waste material in the industry. Glycerol-based saw-chain lubricants has already been successfully developed and applied in harvesters. This project aims on developing and testing glycerol-based lubricating greases to solve issues with skin irritation and difficult cleaning with petroleum-based grease in industry.

PhD project: Tribology of carbon fiber reinforced polymers in gaseous environments
With hydrogen being one of the key pillars to decarbonisation, reliable and efficient hydrogen compression will become increasingly important. In oil-free reciprocating hydrogen compressors, the self-lubricating piston rings and other dynamic seals are critical components in terms of efficiency, service-life and proper functioning. These components are commonly made from carbon fiber reinforced polymer composites. The aim of this project is to investigate the tribology of carbon fiber reinforced polymers in dry gas, focusing on the effect of gas impurities and counterface properties. The project results are expected to be an important foundation for further research in the area.
