Measuring the effect of breakage mode and top size on coal liberation using the RhoVol densimetric analysis machine [PDF]

MATEC Web of Conferences
Coal from the Waterberg coalfield is associated with high mineral that necessitates the need for beneficiation to improve the grade. Comminution is usually employed for ore processing and the liberation of valuable coal macerals from the gangue.

Effects of post-lithography cleaning on the yield and performance of CVD graphene-based devices [PDF]

Beilstein Journal of Nanotechnology, 2019
The large-scale production of high-quality and clean graphene devices, aiming at technological applications, has been a great challenge over the last decade. This is due to the high affinity of graphene with polymers that are usually applied in standard lithography processes and that, inevitably, modify the electrical proprieties of graphene.
