Dear Shervin,
I am not sure about any specific formats. However, I think recommendation letters have not to be written on an any specific formats and I think they are personal. Working in a research center can involve both materials which is shown in a work place like their description of your ability for work group,.... (you can see on such recommendations) and also more expressions of you research ability and your academic bachground.
I think they can add everything that express you as a hardworking, cooperatiove and intelligent reasearcher and others that might be effective.
Although I think you can combine academic and work recom samples in an effective format , you should ask the otheres.
Regards.
