Aqueous nanolubricants containing ZrO2 nanoparticles. graphene oxide (GO) nanosheets. or hybrid nanoparticles of ZrO2 and GO were formulated using a cost-effective ultrasonication de-agglomeration method. The friction and wear characteristics of these water-based nanolubricants were systematically investigated using a block-on-ring testing configuration with a stainless- and alloy ste... https://www.bekindtopets.com/top-offer-MLB-Chicago-White-Sox-Game-Ball-iPhone-11-Impact-Case-p59400-quick-deal/
