Should an engineering product research at a university be always released in a journal?
Unless you have an established relationship with the developers and are willing to, perhaps, sign a non-disclosure agreement, I doubt that a request would be honored.
Sometimes the &quot;work product&quot; is a bit embarrassing (&quot;mistakes were made&quot;) and sometimes it contains proprietary information and trade secrets. There may be things in it that lead to future developments and the team wants to keep those to themselves.
If the work is patented then you can read the patents themselves as they are intended to be public.
