Surface wettability of silicon nanopillar array structures
Feb 05 2021 · Our findings demonstrate that controlled surface wettability can be achieved by combining our controllable gap silicon NP array structures and the surface with or without silicon native oxides. The gap of a Si NP fills with water due to the capillarity on a silicon native oxide but on a pure stable silicon one with a defect-free surface does

The Possibility of Changing the Wettability of Material
The contact angle as a vital measured parameter of wettability of material surface has long been in dispute whether it is affected by gravity. Herein we measured the advancing and receding contact angles on extremely low contact angle hysteresis surfaces under different gravities (1-8G) and found that both of them decrease with the increase of the gravity.

Jul 24 2015 · The wettability of graphitic carbon and silicon surfaces was numerically and theoretically investigated. A multi-response method has been developed for the analysis of conventional molecular dynamics (MD) simulations of droplets wettability. The contact angle and indicators of the quality of the computations are tracked as a function of the data sets analyzed over time.
