Ann: Trading Halt, page-17

Was thinking that wasnt there when I looked earlier either.
Using these different search parameters found a huge number of research papers out of Adeaide looking at numbers of different catalysts. Everything from nanotubes with metals and graphene sheets to infusing graphene with nitrogen and boron and sometimes metals. Wont say that I can understand it all except the bottom line conclusions. A group of chinese named academics with long interests in the area.
I think the latest ones are looking at introducing a metal to nitrogen infused grpahene.
One i found of interest related to a "A Unique Synthesis of Macroporous N-Doped Carbon
Composite Catalyst for Oxygen Reduction Reaction". ( because they are not the only ones researching this area).
Might be completely wrong about the direction of course but kept me up to 2am .
