"What’s so special about Dotz?
The Company has the sole rights to extract GQDs from coal instead of graphite, producing cheaper, non toxic and at ten times the production yield GQDs (25% yield instead of 2% from graphite). Dotz Nano is currently not aware of any other party that is commercialising graphene quantum dots"

Am I reading this right?
That DTZ can get 20% yield from coal?
E.g, from 1 tonne of coal they get 200kg of dots

OR

Are they saying they can get ten times the yield than what is possible from graphite? So, if they got a 100 grams per tonne from graphite, then they could get 1kg per tonne from coal?
