Mar 13, 2003 - Wetting behavior was studied on surfaces with a single, circular heterogeneous island. Lyophobic islands were created on lyophilic Si wafers using polystyrene. Alternately, lyophobic perfluoroalkoxy fluoropolymer film was etched to mak
May 6, 2009 - The contact angle was taken equal to that made by the circle with the solid .... The width of the contact area of the drop with the solid surface is ...
Using a novel minimization technique on the free energy of this system, a generalized Young's equation ... We also propose an equation in the same spirit as these results but valid on a more .... We shall concentrate on simplifying the expression I2
Oct 24, 1998 - We consider a three-dimensional liquid drop sitting on a rough and chemically heterogeneous substrate. Using a novel minimization technique on the free energy of this system, a generalized Young's equation for the contact angle is foun
We consider a three-dimensional liquid drop sitting on a rough and chemically heterogeneous substrate. Using a novel minimization technique on the free energy of this system, a generalized Young's equation for the contact angle is found. In certain l
ACS eBooks; C&EN Global Enterprise .... Phone: 1-952-556-8619. ... As liquid is added to the drop, the contact line advances to the asperity edge and is pinned, Figure .... (b) A small water drop (2 μL) on a much larger sphere (2R = 25.4 mm).
In this paper, we explore the influence of curved surfaces on contact angles. Small liquid drops were deposited at the apex of spheres. Liquid was added to ...
Oct 24, 1998 - In certain limits, the Cassie and Wenzel laws, and a new equivalent rule, applicable in general, are derived. We also propose an equation in ...

signals are desired on metallic surfaces. Not only is surface damage likely, but high-power densities pose significant problems for resonant e~periments,'~ such as the possibility of molecular desorption or degradation, which limits usable pulse energies to
