Langmuir trough

A Langmuir–Blodgett trough (LB trough) is a laboratory apparatus that is used to compress monolayers of molecules on the surface of a given subphase (usually water) and measures surface phenomena due to this compression. It can also be used to deposit single or multiple monolayers on a solid substrate. Visa mer Overview The idea of a Langmuir–Blodgett (LB) film was first proven feasible in 1917 when Irving Langmuir (Langmuir, 1917) showed that single water-surface monolayers could be transferred … Visa mer One of the first scientists to describe and attempt to quantify the spreading of monolayer films on the surface of a liquid was Benjamin Franklin. Franklin described the spreading of a … Visa mer The LB trough has myriad uses, but generally takes on one of two roles. First (as described above), the trough can be used to deposit one or more monolayers of specific amphiphiles onto solid substrates. They are in turn used for different areas of … Visa mer Any type of surface experiment requires maximal cleanliness and purity of components.
