Splay stripe textures in Langmuir monolayers
The Journal of Physical Chemistry, 1993Figure la is an image of the stripe texture in a monolayer of PDA obtained with polarized fluorescence microscopy. The probe was NBD-hexadecylamine at a concentration of 1%; details of the experimental technique are given in ref 6. Stripes related to modulations in the monolayer density have been observed in monolayers13 by fluorescence microscopy with

Structure of langmuir monolayers of substituted phthalocyanines
Materials Science and Engineering: C, 1998Langmuir floating layers of two phthalocyanine derivatives, ytterbium bisphthalocyanine and tetra-tert-butyl nickel phthalocyanine, were investigated by means of compression isotherms, surface potential kinetics and Brewster angle microscopy (BAM) in order to study the influence of peripheral substituents on the structure and stability of these films ...

Thermodynamics of the liquid states of Langmuir monolayers
The Journal of Chemical Physics, 2005The liquid states and the liquid-liquid equilibrium of surfactant molecules forming an interphase between air and water have been considered using Monte Carlo computer simulations. Specifically, the expanded and compressed liquid phases observed for surfactant molecules were characterized as a function of pressure and temperature.

Atomistic Simulations of Langmuir Monolayer Collapse
Langmuir, 2006Monolayers at the vapor/water interface collapse by exploring the third dimension at sufficient lateral compression, either by forming three-dimensional structures or by solubilization into the aqueous solution. In this paper, we provide an atomistic description of collapse from molecular dynamics (MD) simulations.

Micromanipulation of Langmuir-Monolayers with Optical Tweezers
The Journal of Physical Chemistry B, 2000A 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 monolayers on a micrometer scale. The viscoelastic, electrical, and thermodynamic properties of the monolayer can

Sequential Collapse Transitions in a Langmuir Monolayer
Langmuir, 2004Unusual sequential collapse transitions are investigated in a lignoceric acid Langmuir monolayer. The nucleation of monolayer collapse is first initiated in the solid, S, phase but at remarkably low surface pressure where small three-dimensional (3D) granular dots appear.
