Observation of Grease Fluidity in a Ball Bearing Using Neutron Imaging Technology
Tribology Online, 2021 The grease fluidity and migration inside a ball bearing has been visualized non-destructively by using a neutron imaging technology. It has been clarified that a lithium (Li) complex grease with lower torque lubricates in the channeling state and that a ...

Is Corruption an Efficient Grease? [PDF]
SSRN Electronic Journal, 2008 This paper tests whether corruption may act as an efficient grease for the wheels of an otherwise deficient institutional framework. We analyze the interaction between aggregate efficiency, corruption, and other dimensions of governance for a panel of 54 developed and developing countries.
