I guess that most of it is related to the various branches physical sciences (mechanical & materials engineering / fluid dynamics)
The areas that perhaps relate more to conventional chemistry are probably more limited - corrosion; fluid chemistry (fuel / fuel combustion / contaminants / trace substances etc.)
If you can include closely related subjects such as metallurgy, polymer science or tribology as 'chemistry' then you open up a whole raft of options.
Not a lot of helo I know, but might propmt some ideas ! Good luck !
