Sessile Drop & Contact Angle
An international team of experts in the field of wetting led by Dr. Drelich published a one-of-a-kind contribution on the history of contact angles, their meaning, and use in polymer surface energy estimation. The title of the paper is Contact angles: history of over 200 years of open questions and this paper was published in the first (double) issue of 2020 of Surface Innovations. There has been no similar historical perspective on the origins, evolution, scientific use, and healthy criticisms of the existing interpretations of contact angles offered by any other journal. This historical review will well serve researchers across the disciplines, guiding the readers into the scientific meaning of contact angles and their limitations, and providing directions for new developments in the area of science of contact angles.
