Synthesis, redox properties, and langmuir monolayer formation of selected 3d- and 4d- metalloamphiphiles
… interface. The LB studies show that the monolayer stability is maintained up to a pressure of ca. 49 mN/m when collapse occurs. The IRRAS spectra suggest high order of the deposited film.</p> <p>The synthesis and characterization a series of single-tailed copper(II)-containing surfactants …

Design and synthesis of chemically-modified biosorbents for the removal of anionic metals and dye: kinetic and thermodynamic studies
… and after modification was in line with the Langmuir monolayer adsorption model. <br/><br/>By studying the adsorption behavior of banana peel bioadsorbent before and after modified on methylene blue in aqueous solution in detail, when the pH value is higher than 6, it is more beneficial to …

INTERACTION AND PROTECTION OF ANTIMICROBIAL COMPOUNDS WITH CARBOHYDRATE-BASED COLLOIDAL SYSTEMS FOR IMPROVED FOOD SAFETY
… of substitution (DS) interacts with nisin in a Langmuir monolayer adsorption pattern in both non-emulsion and emulsion systems. The monolayer adsorption capacity (Qm) increased in non-emulsion system and was significantly higher in the emulsion system. At the equivalent concentration of PG-OS …

Surface Characterization of Siloxane, Silsesquioxane, and Maleic Anhydride Containing Polymers at Air/Liquid Interfaces
Langmuir-monolayer formation at the air/water interface (A/W) can be achieved by spreading amphiphilic molecules on a liquid subphase and compressing them into an ordered arrangement. The use of the Langmuir-Blodgett technique (LB) to prepare ultra thin films on solid surfaces from monolayers at …

Poly(L-Lactic Acid) Langmuir Monolayers at the Air/Water Interface and Langmuir-Blodgett Films on Solid Substrates: Phase Behavior, Surface Morphology, and Crystallinity
… processes. This dissertation provides the Langmuir-Blodgett (LB) technique as a mechanism for fabricating PLLA substrates at temperatures where PLLA degradation is uncommon. In order to fully understand surface morphologies of PLLA LB-films, studies of Langmuir monolayers at the air/water …

Surface Characterization of Poly (epsilon-caprolactone) at the Air/Water Interface
… This thesis focuses on PCL crystallization in Langmuir monolayers. Brewster angle microscopy (BAM) studies show that square, distorted rectangular, and dendritic crystals form at the A/W interface. While dendritic structures have been observed in poly (ethylene oxide) (PEO) thin film on solid …

Structural and kinetic studies of surfactant and phospholipid monolayers at the air/liquid interface using sum-frequency generation spectroscopy
… on the conformational ordering of the adsorbed monolayer. The structure of a tethered bilayer lipid membrane (tBLM) produced by different methods was investigated. The tBLM is a bilayer of phospholipids, which are tethered to a gold substrate by a self-assembled monolayer (SAM). The SAM is a …
