Organic-inorganic perovskite-like hybrids combine the properties of both the perovskite structure and metal-organic framework compounds. We investigated the magnetic properties of a Cu-based hybrid material grown as a thin film by the Langmuir-Blodgett technique. We show that the long alkyl spacers in the hybrid thin film only …

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.Langmuir-Blodgett films. I. R. Peterson and I. R. Girling. The Langmuir-Blodgett technique for making thin organic films has a number of features not found ...These types of organized coatings are called Langmuir-Blodgett films. For the present experiment, only monolayer Langmuir films will be produced and characterized. Figure 1. Conceptual representation of an expanded (a) and compressed (b) monolayer surfactant film on a water surface.

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 ... The structural complexity of the cell envelope of Gram-negative bacteria limits the fabrication of realistic models of bacterial cell membranes. A vertical Langmuir–Blodgett withdrawing was used to deposit a 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphoethanolamine (POPE) monolayer on the Au(111) surface. The second leaflet composed of di[3-deoxy-D-manno-octulosonyl]-lipid A (KLA) was deposited ... ….

B.1 Film formation: Langmuir and LB films Briefly, films or Langmuir monolayers are formed by extension of an amphiphilic substance, insoluble in water, on the surface of the water or an aqueous solution. The film formed on the air-water interface can be transferred to a substrate, resulting in a Langmuir-Blodgett (LB) film,When Lord Rayleigh (John William Strutt, 3rd Baron Rayleigh, 1842–1919) received a registered letter* from Brunswick in Germany, on the morning of Monday, January 12, 1891, he little thought that this was the opening of a new phase in his physical research and that it would lay the foundation for an entirely new and revolutionary branch of ...Infrared spectroscopic studies of molecular structure, ordering, and interactions in enzyme-containing Langmuir-Blodgett films.
