[Objective] This paper analyzes the fine-grained characteristics of funding and paper data in English, aiming to identify the frontiers of scientific research. [Methods] We retrieved NSF funded projects and WOS papers in the field of carbon nanotubes, and identified their LDA themes. Then, we compared their topic novelty, intensity and similarity. [Results] We found two trending topics, five emerging topics, four dying topics and two topics with potentialities. [Limitations] We did not evaluate our method with data in Chinese. [Conclusions] Compared with methods relying on single data source or dimension, our method can identify the frontiers of scientific research more effectively.
