> I don't see how to open source work requiring a femtosecond mid-infrared laser or a prep requiring a synthesis lab with all the reagents, labware, and safety equipment.
You can put text documents on GitHub describing process, in the same way as you can code and data. If you have some setup with a femtosecond mid-infrared laser or prep requiring a synthesis lab with all the reagents, labware, and safety equipment you can open source the bill of parts, the build instructions and the lab book. It'd probably be very valuable to do that so please do!
