Experimental evidence has made it clear that the size of an object can have an effect on its properties. The electrical resistivity of a thin film will become larger as the thickness of that film decreases in size. Furthermore, the electrical resistivity will also increase as the temperature increases. To help understand these relationships, a model is presented, and equations are obtained to h...

In this contribution we demonstrate a method of synthesizing a hexagonal boron nitride (h-BN) thin film by ambient pressure chemical vapor deposition on polycrystalline Ni films. Depending on the growth conditions, the thickness of the obtained h-BN film is between ∼5 and 50 nm. The h-BN grows continuously on the entire Ni surface and the region with uniform thickness can be up to 20 μm in late...

Traditional radio frequency filters cannot meet the demands of miniaturization, high operation, integration, and broadband capacity in new-generation communication system owing to their larger volumes. A thin film bulk acoustic resonator (FBAR) is therefore suggested as an optimum solution because its small volume a good performance. In this study, COMSOL multiphysics software was used build 2 ...

Objective(s): The purpose of the present study was to prepare and to evaluate a novel niosome as transdermal drug delivery system for propranolol hydrochloride and to compare the in vitro efficiency of niosome by either thin film hydration or hand shaking method. Materials and Methods: Niosomes were prepared by Thin Film Hydration (TFH) or Hand Shaking (HS) method. Propranolol niosomes were pre...

The production of antibacterial and antifungal nanocomposites is widely usedin pharmaceutical, health, food, packaging and medical industries. Meanwhile,the epoxy coating film is one of the most commonly used protective coatings inindustrial applications. In this work, ZnO nanoparticles were first synthesized atthree different concentrations. UV-Vis spectroscopy and dyna...

Epitaxial lead zirconate titanate nanoislands were obtained by a self-patterning method using the instability of ultrathin films during high-temperature treatments. After high-temperature annealing, the as-deposited film breaks into islands with a narrow size distribution. Nanostructures, as small as 20 nm lateral size with a height of 9 nm, were epitaxially grown on Nb-doped (001) SrTiO3 subst...

It has been proposed that young infants, in contrast to adults, base similarities in stimuli across modalities on quantitative aspects rather than on qualitative aspects. To investigate the spontaneous quantitative matching across modalities in adults and infants, 12 adults and 32 infants watched film sequences while their looking behavior was recorded using an eye-tracker. The film sequences d...

In this paper the performance of radiographic film (KODAK X-Omat V) for analysing intensity-modulated (IM) beams in a plane at reference depth (5 cm for 6 MV, 10 cm for 18 MV) was investigated. The field size dependence of the film response was studied for small and medium field sizes. The dose rate dependence of the response and possible effects of fractionating the dose were assessed. In the ...

This work focuses on the study of the dynamic behavior and lattice size dependence of the surface root-mean-square slope in a porous thin film deposition process taking place on a triangular lattice. The simulation results indicate that the expected mean slope square reaches quickly a steady-state value and exhibits a very weak dependence with respect to lattice size variation. The simulation f...

Nanocrystalline cadmium sulfide thin films as antireflection materials for solar cells have been prepared by a new chemical solution deposition route in an aqueous medium at 50 °C. as-deposited thin films were studied using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and optical absorption spectra. X-ray diffraction data indicated the formation of hexagonal na...
