Abstract The modification of photonic nanoarchitectures occurring in butterfly wing scales with different nanostructures was investigated experimentally and by modeling. Single crystalline, polycrystalline, simple thin film, pepper-pot-type the butterflies were investigated. By atomic layer deposition (ALD) (additive) color all red shifted plasma etching (subtractive) blue a controllable way. L...

Interaction of polyadenylic acid, poly(A), with stearic acid Langmuir-Blodgett (LB) monolayer was studied in different electrolyte surroundings. For this purpose LB films of stearic acid, transferred on the mica substrate from poly(A) containing subphase, were analyzed with atomic force microscopy (AFM). The density of polynucleotides surface coverage is ruled by the monovalent electrolyte conc...

The nanoparticle technologies consisting of multiple layers of mixtures of activated carbon and ruthenium (IV) oxide for super capacitors are reported. The mono-particulate layer process described here is a modified Langmuir-Blodgett trough. We report the processes for a spray-coated zinc nanopowder electrode used as a counter-electrode forming a galvanic cell of extremely high charge storage c...

The properties and stability of confined Langmuir]Blodgett multilayers made of arachidic acid were investigated using the surface forces apparatus. Two different types of confined films were studied: one formed by bringing two separate LB films into molecular contact, the other formed by bringing one LB film into direct contact with mica. The measured thickness of confined ̊ Ž . material depends...

High-resolution studies of domain configurations in Langmuir-Blodgett films of ferroelectric polymer poly(vinylidene fluoride-trifluoroethylene), P(VDF-TrFE), have been carried out by means of piezoresponse force microscopy (PFM). Changes in film thickness and morphology cause significant variations in polarization patterns. In continuous films and nanomesas with relatively low thickness/grain ...

The surface force apparatus (SFA) was utilized to obtain force-distance profiles between silica-supported membranes formed by Langmuir-Blodgett deposition of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC). In the absence of a membrane, a long-range electrostatic repulsion and short-range steric repulsion are measured as a result of the deprotonation of silica in water and the roughness of t...

The effect of ultraviolet light irradiation on the characteristics of the polyethylene (PE) surface was investigated by the quartz crystal microbalance (QCM) technique. The PE film was prepared on the gold electrodes of the QCM by spin-coating from the solution and then was treated by the excimer UV lamp in ambient air. The changes in the hydrophilic properties, moisture adsorption, and water r...

organization. When this film was reduced back to AgIITNPc (Figure 1 Ib) with hydrazine, the dichroic ratio declined almost to unity, indicating loss of order. A much thinner film (four layers) was used to repeat the liquid-phase experiment, with the same results being obtained. Thin-film reorganization upon redox sampling undoubtedly involves solvent transfer through the film.32*33 Thus, the lo...

The immobilization of the enzyme tyrosinase (Tyr) in lipid matrices can be explored to produce biosensors for detecting polyphenols, which is relevant food industry. Herein, we shall demonstrate importance composition immobilize Langmuir-Blodgett (LB) films. Tyr could incorporated into Langmuir monolayers arachidic acid (AA), 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) and 1,2-dipalmitoy...
