Dear all, is the relation between chemical composition of a material and its physical properties a peering relation or a relation of subordination？

What are your thoughts on this? Is this for schoolwork?

nope, it's about my PhD project, we are now starting sorting of the recycled materials based on chemical composition, the traditional sorting criteria is mostly based on the physical and mechanical properties, I am thinking of the relation of this hierarchy, and wondering why is a new sorting criteria advantageous or specific over others.

Okay, I've got it now. PhD work has nothing to do with school. Check.

Can you post your outline for your PhD work?
