WebbWe investigate the use of the Wilhelmy plate method to measure the surface pressure in a solid-like Langmuir film under compression. Layers of the protein hydrophobin, which exhibits a high shear elastic modulus, are spread and compressed in a Langmuir trough. The resulting isotherms are classified according to the surface pressure and distance … WebbLangmuir -Blodgett Film. 01_langm131.docx. Further, one can transfer the Langmuir film to an appropriate solid substrate by dipping it in a controlled manner through the film. …

The Past and the Future of Langmuir and Langmuir–Blodgett Films
WebbLangmuir trough (LT) and molecular dynamics (MD) simulations have been carried out to characterise the interaction between OD particles made from a range of surfactants. We also explore the factors that determine the shape of the particles, in particular by the level of overbasing (amount of calcium carbonate in the core), surfactant type and the … WebbBrewster angle of the subphase. The reflected beam goes through the lens with a tenfold magnification to the USB-camera, which transmits the data via the interface module to the computer. Microscope is fixed on the frame above Langmuir trough in such a way that the laser beam would fall in the center of the trough.
