Even with the recent extensive study into superhydrophobic surfaces, the fabrication of such surfaces on the inside walls of a pipe remains challenging. In this work we report a convenient bi-layered pipe design using a thin superhydrophobic metallic... Read More about Drag reduction properties of superhydrophobic mesh pipes.

Drop transport and positioning on lubricant-impregnated surfaces (2017)
Journal Article
