Lubrication fundamentals [PDF]
A lubricant is any substance that is used to reduce friction and wear and to provide smooth running and a satisfactory life for machine components. Lubrication fundamentals are discussed and the various lubrication mechanisms are defined.

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.

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.

Continuous and discrete models of cooperation in complex bacterial colonies
, 1998 We study the effect of discreteness on various models for patterning in bacterial colonies. In a bacterial colony with branching pattern, there are discrete entities - bacteria - which are only two orders of magnitude smaller than the elements of the ...

Boundary lubrication ability of lubricants on slideways.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1988 The newly proposed boundary lubrication model in the previous reports is applied to many surfaces (slideways) and the boundary lubricating ability of lubricants is examined thoroughly. The secondary microconstruction of surface asperities and the load carrying pressure distribution of adsorbed lubricant film in contact are taken into consideration in ...
