Although there are international conventions, there is no completely universal standard for the specific signature position of communication authors, which varies according to the actual situation and national conditions, and the signature order depends on the actual contribution of the paper.

For example, tutors in Europe and America usually put their names last as communication authors. And a big boss in Japan who makes nanomaterials has always put his name in the second place as a correspondent. A research group doing computational materials science in Europe, students contribute their own papers and become the first author and communication author, and the tutor does not star the articles. Although the tutor has made responsible contributions from topic selection to specific work and paper revision.

Extended data:

The original intention of setting up a correspondent is to facilitate the contact between readers and the author of the paper. Because of the mobility of students, postdocs and other personnel, the tutor provides a fixed address (mainly email) as a contact person.

At the same time, the correspondent is also a person who deals directly with the editorial department, and often needs some knowledge and experience. In the current scientific evaluation system, correspondent is regarded as the owner of academic credit of papers. In the case of equal cooperation and equal contribution of several research groups, there will be the same correspondent.
