A monomolecular film system that changes color to indicate the presence of an influenza virus has been developed by a group at the Lawrence Berkeley (CA) Laboratory (LBL) Center for Advanced Materials. Monomolecular film simplifies detection of influenza virus. When a solution of octadecylammonium chloride (CH 3 (CH 2) 17 NH 3 + Cl −: ODAH + Cl −) was spread at an interface between the air and an aqueous dispersion of the negatively charged nanosheets, the nanosheets were adsorbed onto the floating monomolecular film of ODAH + to form a hybrid film at the interface.

In such LB films, pyroelectricity and piezoelectricity can be observed. Due to the small thickness of the multilayers, the pyroelectric response is very fast. Therefore pyroelectric detectors for thermal radiation have been proposed which may be used, for example, in fast infrared TV cameras.
The liquid condensed and liquid expanded physical states in an insoluble monomolecular film at the air-water interface and the gel and liquid crystelline states in fully hydrated bilayers are discussed and compared. It is postulated that, under reasonable restraints, the monolayer may be regarded as an adequate model membrane by: 2.
Quantitative examination of the surface properties of monomolecular films of the isolated microbubble surfactant complex (or glycopeptide–lipid–oligosaccharide complex), at an air/water interface, was carried out using a Langmuir trough apparatus.
Stabilized microbubbles are apparently formed from shrinkage of surfactant-coated macroscopic bubbles, and various data indicate that most of the carbohydrate material is selectively desorbed from the microbubble surfactant monolayer. It is proposed that such a -y vs. T break involves melting of a monomolecular layer adsorbed at the interface.
The large change in slope at the break can be interpreted from the equation (OH/OA)p.T = 7- T(OT/OT)I~,~ with the change in (OH/OA) at the break corresponding approximately to the heat of fusion of a by: Interface Sei.(66) Marra, J.; Israelachvili, J.

The data. An investigation into the energy per unit area of interface formed between monomolecular layers of fatty acids adsorbed on a mica surface and polar and nonpolar liquids is described. The results are compared with values predicted from Young's relation, γ sl = γ sv − γ lv cos θ, where the γ' s represent interfacial energies between solid, liquid, and vapor phases, and θ is the.
DNA adsorption on solid or liquid surfaces is a topic of broad fundamental and applied interest. Here, we study by X-ray reflectivity the adsorption of monodisperse double-stranded DNA molecules on a positively charged surface, obtained through chemical grafting of a homogeneous organic monomolecular layer of N-(2-aminoethyl) dodecanamide on an oxide-free monocrystalline Si().
Phase transitions in the monomolecular film of N-octadecanol on silica gel surface. Journal of Colloid and Interface Science91 (2), DOI: /(83) XPS is an appropriate analytical method for chemical analysis of thin (less than 10 nm) films adsorbed on a surface and the configuration of the molecules and chemical bindings to the substrate.
It is thus apparent that the surface temperature of a layer of water will be dependent upon many environmental factors and can be influenced in several ways by the addition of a monomolecular film to the interface. INTRODUCTION The adsorption of a monomolecular film can significantly change the temperature of a free water surface.
Surface interaction controlled microphase separation leading to the formation of a chemically heterogeneous surface nanopatterns in dry ultrathin films of A−B diblock copolymers is studied theoretically in the strong segregation limit.
On a planar surface one of the blocks (A block) is strongly adsorbed, forming a tightly bound monomolecular layer (two-dimensional melt). aggregation takes place. At the CMC, the interface is at (near) maximum coverage and to minimise further free energy, molecules begin to aggregate in the bulk phase.
Above the CMC, the system then consists of an adsorbed monomolecular layer, free monomers and micellised surfactant in the bulk, with all these three states in equilibrium. States of Monomolecular Films A.

Several experimental evidences differentiating an insoluble monomolecular film just on the air/water interface from an adsorbed film of soluble amphiphile solution are presented in order to. adsorbed at the interface. * Problem arises: how to define the interface between α and β.
* Gibbs’ approach (Gibbs dividing surface): the interface was defined as a position that the surface excess of example substance (always the solvent) becomes zero.- (Fig a, 2b) z Surface excess concentration of i with respect to α substance, Γi.
Langmuir-Blodgett films are formed by the deposition of a Langmuir film onto a solid substrate. Langmuir films are composed of an organized monolayer of amphiphilic molecules at a liquid/gas interface. These molecules, by virtue of possessing a hydrophobic tail and a hydrophilic head, are spontaneously oriented at a liquid/gas interface.

Colloidal dispersions: an overview: the cosmetic scientist must consider various repellent and attractive forces involved in these systems.Films that form at surfaces or interfaces are of special importance. Such films may reduce friction, wear, or corrosion, or may stabilize emulsions, foams, and solid dispersions.
Thin films on water surfaces can reduce evaporation losses, though the spreading of thin films on such surfaces can represent a serious environmental problem.
