In your opinion is both superfluous in the following sentence?
Efforts from both experimentalist and theoretician communities, started to increase over the last decades in order to turn the hydrogen energy from a possible solution to a reality.
I used both, even if it seems superfluous, to show emphasis that, although at the beginning of hydrogen energy research, most of researches were experimentalists, it turns out in the last decades that theoreticians are interested in such fields as well.
A second doubt I have is if the expression "experimentalist and theoretician communities" is correct in the way I'm using it. I've read many times expressions like: "Each session, devoted to a kind of spectroscopy, will include invited contributions from both experimentalists and theoreticians" or "time-scale motions remains a challenge to experimentalists and theoreticians alike". But in my sentence I'd like to make clear that theoreticians and experimentalist working in different fields, as for example catalysis, electrochemistry and computational chemistry, are now given attention to hydrogen energy. That's why I used communities.
In you opinion, does it make sense?
