Piezoviscous effects in nonconformal contacts lubricated hydrodynamically [PDF]
The analysis is concerned with the piezoviscous-rigid regime of lubrication for the general case of elliptical contacts. In this regime several formulas of the lubricant film thickness have been proposed by Hamrock and Dowson, by Dowson et al., and more ...

Hydrogenative Cyclopropanation and Hydrogenative Metathesis
, 2019 The unusual geminal hydrogenation of a propargyl alcohol derivative with [CpXRuCl] as the catalyst entails formation of pianostool ruthenium carbenes in the first place; these reactive intermediates can be intercepted with tethered alkenes to give either

Mechanism of Water Film Acting on Capillary Force in Porous Media of Tight Reservoirs
Liaoning Shiyou Huagong Daxue xuebaoThe water film formed within the pores of tight reservoirs leads to a distinct "oil⁃core water⁃film" configuration in the distribution of oil and water within the porous medium, which has a significant impact on the flow channels and capillary forces of ...

Mechanics of a gaseous film barrier to lubricant wetting of elastohydrodynamically lubricated conjunctions [PDF]
Two analytical models, one based on simple hydrodynamic lubrication and the other on soft elastohydrodynamic lubrication, are presented and compared to delineate the dominant physical parameters that govern the mechanics of a gaseous film between a small
