Near friction free lube discovered
The graphite layers are around 1.3 nanometres, says the paper, with the fullerene balls about .7 nanometres in diameter, with molecular forces keeping the balls spaced evenly.
The report claims that when pressure is applied, it operates at a friction force of less than .4 nanonewtons - that compares to top lubricants exerting one nanonewton.
