We study the spreading of a liquid 2D dipolar droplet in a Langmuir monolayer. Interfacial tensions (line tensions) and microscopic contact angles depend on the scale on which they are probed and obey a scaling law. Assuming rapid equilibration of th

Two-dimensional pendant liquid expanded droplets partially wet the liquid condensed/gas-phase boundaries in methyl octadecanoate Langmuir monolayers. Their shape is described by the Young−Laplace equation including long-range electrostatic interact

Calculations of equilibrium radii of Langmuir-monolayer domains are compared with measurements in the liquid expanded/gas coexistence region of myristic acid. This paper extends the works of McConnell [Proc. Natl. Acad. Sci. 86, 3452 (1989)] to highe

Equilibrium patterns of a Langmuir monolayer of methyl octadecanoate are perturbed on a micrometer length scale using optical tweezers and laser heating. The consecutive electrophoretic motion of circular domains in liquid expanded or gaseous surroun

The effect of electrostatic dipole interactions on the wetting behavior of two-dimensional droplets, approximated by circular segment shapes with contact angle α, is investigated. α depends on the geometric structure far away from the three-phase c

The line tension and relative surface potentials of Langmuir monolayer phases are determined in the three-phase coexisting region gas/liquid expanded /liquid condensed of methyl octadecanoate using the pendant droplet technique. The Young−Laplace e

The ratio of the rotational and translational drag coefficient of a circular liquid condensed Langmuir monolayer domain moved in different phases is measured. A single domain is fixed at its boundary and forced to undergo combined translational and r

A technique for the manipulation of Langmuir-monolayers at the air/water interface is presented. Optical tweezers are combined with fluorescence and Brewster angle microscopy to produce a system capable of mechanical and thermal handling of monolayer

The relative surface potentials of Langmuir monolayer phases at the air/water interface have been determined in the three-phase coexistence region gas/liquid expanded/liquid condensed of methyloctadecanoate. The monolayer is assumed to be in hydrosta

A Langmuir monolayer of methyl octadecanoate in the phase coexistence region liquid expanded/liquid condensed is observed with fluorescence microscopy and mechanically manipulated using optical tweezers. A circular liquid condensed droplet is locally
