Improvement in the water stability and other related functional properties of thin (<50 μm) kafirin protein films was investigated. Thin conventional kafirin films and kafirin microparticle films were prepared by casting in acetic acid solution. Thin kafirin films cast from microparticles were more stable in water than conventional cast kafirin films. Treatment of kafirin microparticles with he...

The main purpose of this work consists on the preparation of single layered molybdenum oxynitride, MoNxOy. The films were deposited on steel substrates by dc reactive magnetron sputtering. The depositions were carried out from a pure Mo target varying the flow rate of reactive gases, which allowed tune the crystallographic structure between insulating oxides and metallic nitrides and consequent...

In this study, the structural and nanomechanical properties of Cu₂O thin films are investigated by X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM) and nanoindentation techniques. The Cu₂O thin films are deposited on the glass substrates with the various growth temperatures of 150, 250 and 350 °C by using radio frequency magnetron sputtering. The XRD re...

Undoped and Mg-doped ZnO thin films were deposited on Si (111) and quartz substrates by using the sol–gel method. Microstructure, surface topography and water contact angle of the thin films have been measured by X-ray diffraction (XRD), an atomic force microscope (AFM) and water contact angle apparatus, respectively. The XRD results show that all the thin films are polycrystalline with a hexag...

Micron-sized subwavelength structured photonic sensors could allow critical thermomechanical phenomena in manufacturing processes to be monitored, while offering tremendous advantages. To implement these novel sensors into real manufacturing processes, the microring sensors can be embedded at critical locations in metallic structures, which are heavily used in hostile manufacturing environments...

Bi2Te3)0.2(Sb2Te3)0.8 compounds thin films on glass substrates are fabricated by a flash evaporated deposition method. In order to enhance the performance of the thin films, annealing in an argon atmosphere is carried out for 1 hour in the temperature range from 200 to 400 C. The structure of the thin films, in terms of homogeneity and crystalline quality, is investigated by means of x-ray mapp...

Oral films, a promising novel drug delivery system, are a strip of single or multilayered, mucoadhesive or non-mucoadhesive, thin polymeric films that are intended to deliver active therapeutic moieties either locally or systemically in oral cavity through sublingual, buccal, palatal, or gastrointestinal absorption [1-3]. In general, films are known by several names including but not limited to...

The chemical bath deposition (CBD) technique was used for the synthesis of the tin oxide (SnO2) thin films. X-ray diffraction (XRD) was employed to find the crystallite size by using Debye Scherrer’s formula. The surface morphology of SnO2 films was analyzed by the scanning electron microscopic (SEM) studies. The FT-IR spectrum exhibits the strong presence of SnO2. The optical properties of the...
