TiC-supported sizeand shape-selected Au nanoparticles with well defined interparticle distances were synthesized by diblock copolymer encapsulation. Atomic force microscopy (AFM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and temperature programmed desorption (TPD) have been used to investigate the correlation between the nanocatalyst morphological/ electron...

Adsorption of DzO on the MgO(100)/Mo(100) surface has been studied using temperature programmed desorption (TPD), reflection absorption infrared spectroscopy (RAIRS) and low energy electron diffraction (LEED). The epitaxially grown MgO(100) films show virtually identical water TPD spectra as the single crystal MgO(100) surface. The first, chemisorbed layer is adsorbed with the plane of the mole...

This paper discusses user study outcomes with teachers who used Language Muse SM a webbased teacher professional development (TPD) application designed to enhance teachers’ linguistic awareness, and support teachers in the development of language-based instructional scaffolding (support) for their English language learners (ELL). System development was grounded in literature that supports the n...

This paper describes the synthesis of ceria catalysts with octahedron, nanorod, nanocube and spindle-like morphologies via a template-free hydrothermal method. The surface morphologies, crystal plane and physical-chemical structures were investigated via field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopy...

Thermo-exfoliated graphite (TEG)/CuO/Cu2(OH)3NO3:(Co/Fe) composites were prepared using a wet impregnation method and subsequent thermal treatment. The physicochemical characterization of the composites was carried out by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM) and Ar temperature-desorption techniques. The catalytic efficiency toward CO conversion to CO2 was examined...

Intelligent reflecting surface (IRS) is a promising solution to build programmable wireless environment for future communication systems, in which the reflector elements steer incident signal fully customizable ways by passive beamforming. In this paper, an IRS-aided secure spatial modulation (SM) proposed, where IRS perform beamforming and information transfer simultaneously adjusting on-off s...

background: mixed cereals and legumes products enhance protein quality. this study has been conducted to compare the protein value of two homemade foods (a mixture of beans and rice and a mixture of vetch and rice) with a commercial baby food (wheat- based cerelac) in rats. methods: an experimental study has been conducted on 80 male rats, which divided into 8 subgroups. five different diets in...

Adsorption and thermal decomposition of H2S on Si(1 0 0)-2 1 are studied by means of temperature-programmed desorption (TPD) and X-ray photoemission spectroscopy (XPS) with synchrotron radiation. The H2S molecule dissociates to form H and HS on the Si surface at adsorption temperature of 115 K. The Si(1 0 0)-2 1 surface structure is conserved upon the adsorption of H2S due to bonding of dissoci...

The adsorption and bonding configuration of CO on clean and Zn-covered Pd(111) surfaces was studied using Low Energy Electron Diffraction (LEED), Temperature Programmed Desorption (TPD) and High Resolution Electron Energy Loss Spectroscopy (HREELS). LEED and TPD results indicate that annealing at 550 K is sufficient to induce reaction between adsorbed Zn atoms and the Pd(111) surface resulting ...
