As the measurements are typically done in Langmuir troughs, the images can be taken as a function of surface pressure (i.e. packing density of the molecules). Brewster angle microscopy is used to study the properties of the Langmuir layer or to indicate the suitable surface pressure for the Langmuir-Blodgett deposition.May 27, 2019 · The paper deals with the cholesterol–cyclosporine A (Chol–CsA) monolayers at the air/water interface investigated using the Langmuir trough coupled with the Brewster’s angle microscopy. The compressed films were transferred onto the PEEK polymer support by means of the Langmuir–Blodgett technique. To improve molecules adhesion and organization the PEEK surface was treated with air ... Jan 15, 2023 · Almost all Langmuir-Blodgett (LB) films were prepared with the classical Langmuir film balance, developed more than a century ago. To date, the success of the classical Langmuir film balance and the LB transfer technique is primarily restricted to the study of self-assembled monolayers at the air-water surface. Energy and Environment. With a master's degree in hand at age 19, Katherine Blodgett (1898-1979) was the first female scientist to be hired by General Electric's Research Laboratory in Schenectady, New York in 1917. She first assisted Irving Langmuir (Nobel Prize in Chemistry, 1932) with his work on monomolecular coatings - oily chemical ...

Jul 15, 2023 · Fabrication of LAMs by Langmuir-Blodgett assembly. The formation of LAMs was investigated using a Langmuir-Blodgett (LB) trough (KN 2002; Biolin Scientific/KSV NIMA, Sweden). LAMs were fabricated by equimolar mixing of CNP (CNP/CULC or CNP/CENP), cholesterol, and stearic acid. Langmuir-Blodgett deposition is a popular route to produce thin films of graphene oxide for applications such as transparent conductors and biosensors. Unfortunately, film morphologies vary from sample to sample, often with undesirable characteristics such as folded sheets and patchwise depositions. …
