Could you please share some experiences with our readers?Step-by-step. Specifically, by merging our background on catalytic alkylation of arenes with an emerging area (at that time) such as homogeneous gold catalysis.What is the most important personality for a researcher?? Leadership, attitude in motivating early-stage scientists and capability of combining scientific inputs of different heritage for a single and ultimate goal.展开更多
