2019-6-18Herein we demonstrate that hexagonal boron nitride nanosheets h-BNNSs can be used as water dispersible lubricant additive through simple fluoride modification. The fluorination of h-BNNSs F-BNNSs is carried out via a facile ball milling of commercial h-BN microflakes in ammonia fluoride solution. The as-obtained F-BNNSs exhibit excellent antifriction and antiwear performance as water

We report a systematic investigation of the thermoelectric properties of n-type Ga-doped ZnO synthesied using different ball milling conditions. Samples fabricated by the high-energy ball milling resulted in a highly dense layered structure with randomly distributed voids. These samples measured the lowest room temperature thermal conductivity i.e. 27 WmK due to increased phonon scattering
