Make Graphene with an Oxy-Acetylene Torch?

It’s been discovered by University of Kansas researchers that filling a chamber with acetylene and oxygen, the same gasses used in welding and cutting torches, can produce quantities of graphene when ignited by spark plug at one atmosphere.

The engineers in the room will be thinking oxy-acetylene soot:


rotting fruit and veg, compost pile emissions, and growing trees produce ethylene, and trees tend to emit it during drought.

It makes this person wonder whether other wood/biochar/biodigestor gases could also be made to work.
