Article entitled "Investigation on tribological performance of CuO vegetable-oil based nanofluids for grinding operations" co-authored by Dr. Mehdi Kiyasatfar, faculty member at Khazar University Department of Mechanical Engineering was published in "Advances in Manufacturing", an international journal from Springer collection. 

In this study, the tribological performance of CuO nanoparticles in a vegetable oil-water (V/W) emulsion as base fluid was investigated for their ability to improve surface quality in abrasive machining. The results of pin-on-disk tests revealed that adding nanofluids containing 0.5% and 1% (mass fraction) CuO nanoparticles to the base fluid reduced the wear rate by 66.7% and 71.2%, respectively, compared with pure lubricant. The lubricating action of 1% (mass fraction) CuO nanofluid reduced the ground surface roughness by up to 30% compared with grinding using lubricant without nano-additives.
