Australian scientists have turned ordinary cooking oil into graphene, in a discovery they say lowers its cost to produce.
Graphene, a strong carbon material, is just one atom wide and conducts electricity better than copper.
Now researchers say they can make graphene with soybean oil, potentially making it more commercially viable.
Graphene is hoped to have numerous applications including in electronics, biomedical devices and water filtration.
“One of the limiting factors in utilising graphene is the high price compared to other materials,” said Dr Zhao Jun Han from Australia’s Commonwealth…
