WebOption-1: If you are preparing the graphene oxide (GO) using a modified Hummer's method (step-1) you need to obtain the pH of the GO dispersion close to 7 through centrifugation. Step-2: Now, you... Solid lubricants are useful for conditions when conventional lubricants are inadequate, such as: • Reciprocating motion. A typical application is a sliding or reciprocating motion that requires lubrication to minimize wear, as, for example, in gear and chain lubrication. Liquid lubricants will squeeze out while solid lubricants do not escape, preventing fretting, corrosion, and galling. • Ceramics. Another application is for cases where chemically active lubricant additives have not …
