Dr. Jian Liu became a postdoc in the Chalmers University of Technology since June, 2020. His project in Chalmers is ‘plastic plasmonic hydrogen sensors’. In this project, palladium nanoparticles will be incorporated into the matrix of electrically conducting plastics for hydrogen sensing. This study has profound impact not just for foundamental understanding but also for commercail applications such as automotive industry and manufacturers of hydrogen safety systems. Before joining Chalmers, He was a postdoc in Groningen University and worked on the subject of ‘molecular doping of conjugated polymers and organic thermoelectrics’. He received a Ph.D degree in polymer physics and chemistry in Changchun Institute of Applied Chemistry in China. During the PhD study, he worked on interface engineering of polymer photovoltaics. He coauthored over 30 peer-reviewed papers and his broad interest of research includes organic electronics, new energy generation, and Sensors.
