A common feature of greases is that they possess high initial viscosities, which upon the application of shear, drop to give the effect of an oil-lubricated bearing of approximately the same viscosity as the base oil used in the grease. This change in viscosity is called shear thinning. Grease is sometimes used to describe lubricating materials ...
2) and lubricant oil are miscible, i.e. form a single phase upon mixing. [1] [2] The value gives an approximation for the content of aromatic compounds in the oil, [2] since the miscibility of aniline, which is also an aromatic compound suggests the presence of similar (i.e. aromatic) compounds in the oil. The lower the aniline point, the ...
Mathematical Tables from Handbook of Chemistry and Physics was originally published as a supplement to the handbook up to the 9th edition (1952); afterwards, the 10th edition (1956) was published separately as CRC Standard Mathematical Tables. Earlier editions included sections such as "Antidotes of Poisons", "Rules for Naming Organic Compounds ...

Typically lubricants contain 90% base oil (most often petroleum fractions, called mineral oils) and less than 10% additives. Vegetable oils or synthetic liquids such as hydrogenated polyolefins , esters , silicones , fluorocarbons and many others are sometimes used as base oils.
The oil and the oil filter need to be periodically replaced; the process is called an oil change. While there is an entire industry surrounding regular oil changes and maintenance, an oil change is a relatively simple car maintenance operation that many car owners can do themselves.
A lubricant, aka lube, is a liquid, made of silicone, water, or oil, used during sexual activity to reduce friction by making the genital skin feel smoother, either solo or with a partner, says ...
The lubricity of a substance is not a material property, and cannot be measured directly. Tests are performed to quantify a lubricant's performance for a specific system. This is often done by determining how much wear is caused to a surface by a given wear-inducing object in a given amount of time. Other factors such as surface size ...
