TL;DR: In this article, the equilibrium of an axisymmetric sessile drop resting on a thin, elastic plate has been considered using the minimum free energy hypothesis, and it is conjectured that the axisymetric configuration may not always be the most likely.
Abstract: Following an earlier paper, the equilibrium of an axisymmetric sessile drop resting on a thin, elastic plate has been considered using the minimum free energy hypothesis. A consequence is that although Young's equation is still obeyed at the triple line when considering the true contact angle, the apparent contact angle (i.e. with respect to the horizontal) invokes parameters other than simply the interfacial free energies, such as the drop volume and elastic properties of the solid. A quantitative estimate of apparent contact angle dependence on plate thickness has been made in the case of small drops. Finally, consideration of stability, again using the minimum free energy hypothesis, suggests that the axisymmetric configuration may not always be the most likely. This, it is conjectured, may have consequences in cell biology.

TL;DR: In this paper, surface modification of polyimide films such as Kapton E(N) and Upilex S by argon plasma was investigated because of the enhanced adhesive strength with sputtered copper.
Abstract: Surface modification of polyimide films such as Kapton E(N) and Upilex S by argon plasma was investigated because of the enhanced adhesive strength with sputtered copper. Peel tests demonstrated this improvement, with a peel strength of 0.7 and 1.2 g/mm for unmodified Kapton E(N) and Upilex S, respectively, and 110.3 and 98 g/mm for argon plasma–modified Kapton E(N) and Upilex S, respectively, in certain plasma conditions. This study showed that the enhanced adhesive strength of polyimide films with sputtered copper by argon plasma was strongly affected by the surface characteristics such as surface morphology and surface energy of polyimide films. Atomic force microscopy and the sessile drop method indicated that the surface roughness and surface energy of the polyimide films were greatly increased by argon plasma, resulting in highly increased peel strength of the polyimide films with sputtered copper. It was observed in electron spectroscopy for chemical analysis (ESCA) that the increased surface energy of the polyimide films from argon plasma was a result of more of the surface being composed of O and N and of the increased number of CO, CO, and CN chemical bonds. © 2005 Wiley Periodicals, Inc.
