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 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...
متن کاملFlow-induced patterning of Langmuir monolayers.
Insoluble monolayers on water have been patterned at the macroscopic scale (i.e., at the centimeter scale of the flow apparatus) as well as the mesoscopic scale (i.e., down to the micron scale resolvable via optical microscopy). The macroscopic patterning at the air/water interface results from a hydrodynamic instability leading to a steadily precessing flow pattern. The velocity field is measu...
متن کاملLangmuir monolayers of bent-core molecules.
A systematic study of five different, symmetric bent-core liquid crystals in Langmuir thin films at the air/water interface is presented. Both the end chains (siloxane vs hydrocarbon) and the core (more or less amphiphilic) are varied, to allow an exploration of different possible layer structures at the interface. The characterization includes systematic surface pressure isotherms, Brewster an...
