molybdenum thin films with 50 and 150 nm thicknesses were deposited on silicon substrates, using dc magnetron sputtering system, then post-annealed at different temperatures (200, 325, 450, 575 and 700°c) with flow oxygen at 200 sccm (standard cubic centimeter per minute). the crystallographic structure of the films was obtained by means of x-ray diffraction (xrd) analysis. an atomic force micr...

A high transmittance polymer-stabilized blue-phase liquid crystal display with floating electrodes in conjunction with protruded electrodes is proposed. The floating electrodes help to confine the electric field and reduce the dead zone areas. As a result, the peak transmittance over 90% is achieved. Author

Abstract This work has been done in three steps. First, the preparation of acrylate monomers; they are [dimethyl-1,3-dioxoylan-4-yl-methylacrylate (sol-ketal acrylate) (SKA)], [4-acetylphenyl (APHA)], and [4-formyl-2-methoxyphenylacrylate (VA)]. All monomers were evaluated using 1 H, 13 C-NMR, FT-IR. In next step, two kinds polymers prepared. Two series copolymers terpolymers carried out via fr...

In this paper the clear-sky infrared radiation field of the Earth-atmosphere system is characterized by the spectral decomposition of the simulated upward and downward flux density components into three distinct wave number regions. The relative contributions of the far infrared, middle infrared, and windows spectral regions to the total longwave flux densities have been established. The approx...

Photovoltaic performance can be efficiently enhanced by improving the transmittance of solar cell cover, but heating from unavailable irradiation has significantly adverse impact on both efficiency and reliability cells. Radiative cooling passively dissipate heat to cold space (?3 K) through atmospheric window (8–13 ?m). In this work, we reported a high-performance scalable radiative cooler for...

This article describes how the dimensions of nanowires affect the transmittance and sheet resistance of a random nanowire network. Silver nanowires with independently controlled lengths and diameters were synthesized with a gram-scale polyol synthesis by controlling the reaction temperature and time. Characterization of films composed of nanowires of different lengths but the same diameter enab...

Abstract Hydrogels had gained considerable importance in drug delivery systems. Polyacrylic acid/acrylamide (AAc/AAm) and polyacrylic doped with magnetite (AAc/AAm)Fe 3 O 4 hydrogels have been prepared by ɣ -radiations characterized Fourier transform infrared spectra (IR), X-ray diffractions (XRD), scanning electron microscope (SEM) transmittance (TEM). The morphology the particle size were det...

In current work, GO@SiO2 nanocomposite was prepared by coating nanoscale silica onto graphene oxide (GO). characterized with scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (IF-IR). Additionally, the demulsifying performance of investigated bottle test. The results showed that had a good in both oil-in-water (O/W) water-in-oil (W/O) emuls...
