Collapse mechanisms of Langmuir monolayers.
When a two-dimensional (2D) film is compressed to its stability limit, it explores the third dimension via collapse. Understanding this 2D-to-3D transition is of great importance as it provides insight into the origin of defects in thin films. This review draws attention to a reversible folding collapse first discovered in model lung surfactant systems and explores the driving forces for this m...
متن کاملPhotosystem I in Langmuir-Blodgett and Langmuir-Schaefer monolayers.
Photosystem I (PSI) is a membrane protein complex that generates photoinduced electrons and transfers them across the thylakoid membrane during photosynthesis. The PSI complex, separated from spinach leaves, was spread onto the air-water interface as a monolayer and transferred onto a gold electrode surface that was precoated with a self-assembled monolayer (SAM). The electrochemical properties...
متن کاملOrdering by collapse: formation of bilayer and trilayer crystals by folding Langmuir monolayers.
Neutron and synchrotron X-ray studies of arachidic-acid monolayers compressed to the collapse region, beyond their densely packed molecular area, reveal that the resulting structures exhibit a surprising degree of reproducibility and of order. The structure of the collapsed monolayers differs for films that are spread on pure water or on CaCl2 solutions. On pure water, the collapsed monolayer f...
متن کاملFluorinated Langmuir monolayers are more viscous than non-fluorinated monolayers.
The surface shear viscosity of the liquid expanded phase in Langmuir monolayers of fluorinated alcohols differs by orders of magnitude from the corresponding surface shear viscosity of Langmuir monolayers of their non-fluorinated counterparts. The line tension between the liquid expanded and the gaseous phase on the other hand is of similar magnitude for both fluorinated and non-fluorinated sur...
متن کاملLangmuir monolayers of mesomorphic monomers and polymers
2014 Monolayers of organic compounds which exhibit liquid crystalline behaviour in their bulk phases have been formed at an air-water interface. All selected polymers and monomers were of the same basic structure with a rigid aromatic central core containing several hydrophilic ester groups and two or more aliphatic hydrocarbon chains. Spreading was satisfactory in most cases and the surface pr...
