[warning] This position is now closed. [/warning] In the frame of a project financed by Toyota, the LCS recruits a post-Doc likely to start as soon as possible. The project aims at gaining further knowledge on a specific deNOx catalytic process: the NOx trap one. The comprehension work will be directed towards crucial questionsRead more
