Effect of Surface‐Lubricant Compatibility on Bubble Formation in Lubricant‐Infused Surfaces

Advanced Materials Interfaces, EarlyView.
Lubricant‐infused surfaces reduce drag partly through bubbles that form when lubricant depletes. Using laser‐textured steel infused with silicone oil, we show that microbubble nucleation occurs even on surfaces fully wetted by the lubricant, regardless of chemistry.

Numerical analysis for elucidation of mechanical interaction between an erythrocyte moving in medium subject to inclined centrifugal force and endothelial cells on a plate

Journal of Fluid Science and Technology, 2016
Elucidation of the mechanical interaction between an erythrocyte and an endothelial cell is an important issue that may lead to clarification of mechanisms of cardiovascular diseases and development of new treatments. In order to clarify the interaction,

Bistable Wetting States on a Smooth Surface

Advanced Materials Interfaces, EarlyView.
Droplets on non‐textured surfaces typically exhibit a monostable wetting state. Here, we show that droplets can exhibit bistability even without surface texture. We investigate water droplets on a smooth substrate immersed in oil. We find that molecular modulation causes the droplet states to bifurcate into either a sticking or a repellent state ...

Acoustic measurement of lubricant-film thickness distribution in ball bearings [PDF]

, 2006
An oil-film thickness monitoring system capable of providing an early warning of lubrication failure in rolling element bearings has been developed. The system is used to measure the lubricant-film thickness in a conventional deep groove ball bearing ...

Anti‐Slip Material‐Based Strategies and Approaches

Advanced Materials Technologies, EarlyView.
This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

The Theory of Lubrication

Transactions of the Japan Society of Mechanical Engineers, 1951
When we deal theoretically with the subject of the lubrication, we treat it on the supposition that the viscosity of the lubricant is constant for the convenience of the calculation. But we can't regard it as constant, owing to the fact that the lubricant in bearing is affected by the pressure and temperature.
