ball milling method for fe o

NanoFe2O3 and Ndoped graphene was prepared via a onestepball milling method. The maximum power density of FeNG in MFC was 390 of that of pristine graphite. Active sites like nano Fe2O3 pyridinic N and FeN groups were formed in FeNG. The improvement of FeNG was due to full exposure of active sites on graphene.

A smallerballinterpolated exposes more of the surface to a faster moving cutter, leading to a better finish. But, the smaller cutter can flex more. Hence the need to balance these two factors. If you have a 4th axis or 5-axismill, you can try “Sturz”millingto combat the slow moving tip. See below for details.
