Photoswitching Conduction in Framework Materials
This mini‐review summarizes recent advances in state‐of‐the‐art proton and electron conduction in framework materials that can be remotely and reversibly switched on and off by light. It discusses the various photoswitching conduction mechanisms and the strategies employed to enhance photoswitched conductivity.

Study on mixed lubrication characteristics of piston/cylinder interface of variable length
Aiming at the lubrication problem of piston/cylinder interface of variable length, a two-dimensional mixed lubrication model was established. This model considers the adaptive eccentricity and the force balance of the piston.

On the numerical solution of the dynamically loaded hydrodynamic lubrication of the point contact problem [PDF]
The transient analysis of hydrodynamic lubrication of a point-contact is presented. A body-fitted coordinate system is introduced to transform the physical domain to a rectangular computational domain, enabling the use of the Newton-Raphson method for ...

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 ...
