Splay stripe textures in Langmuir monolayers

The Journal of Physical Chemistry, 1993
Figure 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, 1998
Langmuir 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 ...

Polyoxometalate Monolayers in Langmuir–Blodgett Films

Chemistry – A European Journal, 2005
AbstractLangmuir and Langmuir–Blodgett (LB) films of a variety of polyoxometalates of different shapes, sizes, and charges were prepared by taking advantage of the adsorption properties of these polyanions on a positively charged monolayer of an organic surfactant spread on water. Three different aspects were investigated.

Thermodynamics of the liquid states of Langmuir monolayers

The Journal of Chemical Physics, 2005
The 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, 2006
Monolayers 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, 2000
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 monolayers on a micrometer scale. The viscoelastic, electrical, and thermodynamic properties of the monolayer can

Sequential Collapse Transitions in a Langmuir Monolayer

Langmuir, 2004
Unusual 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.

Thermodynamic Aspects of Cholesterol Effect on Properties of Phospholipid Monolayers: Langmuir and Langmuir–Blodgett Monolayer Study

The Journal of Physical Chemistry B, 2013
Cholesterol is an important component of lipid rafts in mammalian cell membranes. Studies of phospholipid monolayers containing cholesterol provide insight into the role of cholesterol in regulating the properties of animal cells, raft stability, and organization.
