We successfully fabricated (chitosan/alginate) (CHI/ALG) multilayer thin film by layer-by-layer (LBL) method. Film durability was enhanced by forming cross-linking using heat treatment, glutaraldehyde, and calcium chloride. Indeed, the adsorption of fibrinogen onto CHI/ALG multilayer thin film was determined by QCM system and it was found that physical stability and protein resistance of CHI/AL...

A nominally room temperature photochemical method, simply employing ultraviolet light(187-254 nm) generated ozone environment, is shown to provide an efficient alternative for the removal of surfactant templates for a routine production of mesoporous silica thin films at low temperatures. The treatment concomitantly strengthens the silicate phase by fostering the condensation of unreacted silan...

Objective(s): The aim of this study was to determine cytotoxic effect of nanoliposomal form of lyophilized aqueous extract of Ecballium elaterium fruit on gastric cell line (AGS) using cell viability tests. Methods: An aqueous extract of the fruits of Ecballium elaterium was prepared. Nanoliposomal form was also prepared by thin-film hydration...

Optical properties, which determine the application of optical devices in different fields, are the most significant properties of optical thin films. In recent years, Metal-organic framework (MOF)-based optical thin films have attracted increasing attention because of their novel optical properties and important potential applications in optical and photoelectric devices, especially optical th...

Zinc oxide thin films have been obtained on bare and GaN buffer layer decorated Si (111) substrates by pulsed laser deposition (PLD), respectively. GaN buffer layer was achieved by a two-step method. The structure, surface morphology, composition, and optical properties of these thin films were investigated by X-ray diffraction, field emission scanning electron microscopy, infrared absorption s...

Many clinical laboratories do immunoelectrophoresis for qualitative assessment of proteins in biological fluids. Commercial kits are available that supply some or all of the necessary components, but the nature of these components varies. Seeking a reliable method for most easily preserving the original immunoelectrophoresis pattern as a permanent record, we compared a thick-film agar method to...

New thin-film Josephson junctions have recently been tested in which the current injected into one of the junction banks governs Josephson phenomena. One thus can continuously manage the phase distribution at the junction by changing the injected current. A method of calculating the distribution of injected currents is proposed for a half-infinite thin-film strip with source-sink points at arbi...

We developed a new method for characterizing molecular distribution in very thin liquid crystal layer (5–40 nm) evaporated onto rubbed polyimide film used by grazing-incidence X-ray diffraction (GIXD). The diffraction peaks corresponding to intermolecular correlation perpendicular to longitudinal axis of liquid crystal molecule and the clear anisotropic distribution of liquid crystal molecules ...

Unintentionally formed nanocrystalline graphene (nc-G) can act as a useful seed for the large-area synthesis of a hexagonal boron nitride (h-BN) thin film with an atomically flat surface that is comparable to that of exfoliated single-crystal h-BN. A wafer-scale dielectric h-BN thin film was successfully synthesized on a bare sapphire substrate by assistance of nc-G, which prevented structural ...
