Wetting phenomena in multi-phase systems govern the shape of the contact line which separates the different phases. For liquids in contact with solid surfaces wetting is typically described in terms of contact angle. While in macroscopic systems the contact angle can be determined experimentally, on the molecular scale contact angles are hardly accessible. Here we report the first direct experi...

This paper presents first a numerical investigation into a novel class of wave motions in narrow open channels. The distinctive condition on these motions is that: – dissipation in vicinity of contact line is described by De Gennes approach; – the macroscopic lines of contact between the free surface and the sides of the channel move with velocity proportional to cosine of dynamic contact angle...

BACKGROUND The aim of this study was to assess the combined use of a high-reflective index vitrectomy (HHV) meniscus contact lens and a noncontact wide-angle viewing system in vitreous surgery. METHODS Twenty-three gauge vitrectomy was performed with combined use of a HHV meniscus contact lens and a noncontact wide-angle viewing system. When delicate manipulation of the retina such as interna...
