Layered rare-earth hydroxide crystallites self-assembled at the hexane/water interface were transferred to various substrates to form a monolayer film, which exhibited photoluminescence properties and ion-exchange ability.

the sorption isotherm and state diagram of sundried, golden and sultana raisins were constructed for investigation and comparison of the product stability. the isotherms were measured at 15, 25 and 35 °c using an isopiestic method and the data were modeled with gab model. glass transition temperatures of the products were measured by differential scanning calorimetery (dsc) and fitted to gordon...

Experimental evidence is presented, demonstrating the feasibility of a surface-patterning strategy that allows stepwise electrochemical generation and subsequent in situ metallization of patterns of carboxylic acid functions on the outer surfaces of highly ordered OTS monolayers assembled on silicon or on a flexible polymeric substrate. The patterning process can be implemented serially with sc...

2014 Glycerol mono-oleate monolayers at the air-water interface have been investigated by quasielastic light scattering from thermally excited capillary waves over a wide range of wave numbers. Using a relatively novel data analysis procedure four surface viscoelastic properties were deduced ab initio from the light scattering data : surface elastic moduli and viscosities governing shear normal...

Mixed Langmuir monolayers are ideal systems to mimic biological membranes [1, 2]. Studies on mixed monolayers provide information about the interactions involved, miscibility and stability of the monolayer. It is known that cholesterol(Ch) is found in bilayer membranes and lipoproteins. Ch regulates the transport and barrier properties of the membranes [3]. Lung surfactant in the human body is ...

The spontaneous formation of the phospholipid bilayer underlies the permeability barrier function of the biological membrane. Tears or defects that expose water to the acyl chains are spontaneously healed by lipid lateral diffusion. However, mechanical barriers, e.g., protein aggregates held in place, could sustain hydrophobic defects. Such defects have been postulated to occur in processes suc...

The droplet interface bilayer (DIB)--a method to assemble planar lipid bilayer membranes between lipid-coated aqueous droplets--has gained popularity among researchers in many fields. Well-packed lipid monolayer on aqueous droplet-oil interfaces is a prerequisite for successfully assembling DIBs. Such monolayers can be achieved by two different techniques: "lipid-in", in which phospholipids in ...

Mixtures of HS(CH2)16CO2H and HS(CH2)1oCH3 adsorb onto gold from solution in ethanol and form densely packed, oriented monolayers. These monolayers expose a combination of polar carboxylic acid groups and nonpolar methyl groups at the surface. Varying the concentrations of the two thiols in solution allows the density of carboxylic acids at the surface and the polarity of the monolayer-liquid i...

Using a three-phase system, centimeter-scale monolayer gold nanoparticle (Au NP) films have been prepared that have long-range order and hydrophobic ligands. The system contains an interface between an aqueous phase containing Au NPs and an oil phase containing one of various types of amine ligands, and a water/air interface. As the Au NPs diffuse to the water/oil interface, ligand exchange tak...
