Hello @emiliomoron, this is an excellent cathedra of organic chemistry that I found in your post, I am only a civil engineer but at some point I get involved with the chemical composition of certain materials.

For example, I think I only had in mind the use of iron and cobalt (this being one of the most famous in Venezuela)

And about what you mention about extraction control that Japan will establish, I wonder what would happen with a drastic decrease in the use of this resource?

Thanks for this great contribution
