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://parisnaturalfoodes.shop/product-category/vegetarian-omega-3/
