Optimisation of the Wax and Oil Phases in a Conventional Lipstick Using Mixture Design [PDF]

, 2014
Lipstick is essentially a mixture of oils, waxes and pastes. The type and ratio of ingredients in the lipstick base determine the type and intensity of interactions, which directly affect the quality of lipstick.

The in-vacuo torque performance of dry-lubricated ball bearings at cryogenic temperatures [PDF]

The performance of dry-lubricated, angular contact ball bearings in vacuum at a temperature of 20 degrees K has been investigated, and is compared with the in-vacuo performance at room temperatures. Bearings were lubricated using dry-lubricant techniques
