Contact line instability

WebOur approach is based on a drying-driven dynamic assembly process occurring on a liquid surface with the stripe pattern formed by a new type of contact-line instability. Periodic ordering of NCs is realized on microscopic and nanoscopic scales simultaneously without the need of any specialized equipment or the application of external fields. Webfingering instability at the moving contact line of a spreading thin film. Numerous experimental and analytical/numerical studies have examined the dynamics of a gravity-driven contact line following the famous study of Huppert [9]. Schwartz [10] proved the contact line instability is controlled by surface tension effects. Troian et al. [11 ...
