Influence of Li Grease Thickener Types on Film Thicknesses Formed between Smooth and Dented Surfaces
Tribology Online, 2017 The lubricant film thickness behaviors of lithium (Li) thickener type greases and their base oil were investigated for the contact between a glass disk and a smooth/dented steel ball using an optical interferometry. The main focus is to understand grease

Breed-specific lipid-related gene expression in the subcutaneous fat of Large White and Erhualian pigs at weaning [PDF]
Archives Animal Breeding, 2015 The Erhualian (EHL) pig possesses significantly lower growth rates and higher adipose deposition compared with the Large White (LW) pig. To further understand the mechanism of breed lipid deposition difference at the early postnatal age, we employed an ...

Effect of Formulation of Li Greases on Their Flow and Ball Bearing Torque
Tribology Online, 2016 This paper describes a study on the effect of base oil type and thickener type on bearing torques with Li type greases. Using a ball bearing tribometer equipped with a torque sensor, friction torque behaviors were determined for model Li greases with ...
