Bibliographic coupling networks reveal the advantage of diversification in scientific projects

作者：

Highlights：

• We use data from the acknowledgements of papers to study research projects.

• Both articles per project and projects per article follow power-law distributions.

• There is sublinear relationship between projects core research fields and project scale.

• Dispersion of research fields in a project can lead to more impactful and original papers.
