Pre-adsorption of water molecules on a material surface, followed by assembly of a van der Waals (vdW) structure, provides a vdW water gap with a height that can be precisely tuned through variation of the amount of water adsorbed at the interface. This approach is applicable to different tw...
While many genre researchers have examined the rhetorical structure of research articles in various disciplines, few have investigated the complete structure of articles for students in engineering, a discipline that includes a wide range of fields. Using Swales’ move framework (1990), this paper ana...
