The nucleation and growth of Au clusters supported on SiO2/Mo(1 1 0) has been studied by X-ray photoelectron spectroscopy (XPS), low energy ion scattering (LEIS), and temperature programmed desorption (TPD). Stoichiometric ultra-thin SiO2 films were synthesized and characterized by Auger electron spectroscopy (AES) and XPS. At 300 K, the growth mode of Au at fractional monolayer coverages is qu...

Four low molecular weight compounds-three of them new, two of them with carbazole (Cz) as functional group and the other two with thienopyrroledione (TPD) group-were used as emitting materials in organic light emitting diodes (OLEDs). Devices were fabricated with the configuration ITO/PEDOT:PSS/emitting material/LiF/Al. The hole injector layer (HIL) and the emitting sheet were deposited by spin...

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...

Organic light-emitting diodes made of tris-8-(hydroxyquinoline) aluminum as the electron-transport layers, N, N -diphenyl-N, N bis (3-methylphenyl)-1, 1 -biphenyl-4,4 -diamine (TPD) as the hole-transport layers, and 2-(1, 1-dimethylethyl)-6(2-(2, 3, 6, 7-tetrahydro-1, 1, 7, 7-tetramethyl-1H, 5H-benzo(ij) quinolizin-9-yl) ethenyl)-4H-pyran-4-ylidene) propanedinitrile (DCJTB) as the guest dopant ...

abstract: â in this study, the change in the crystalline structure of gas hydrate was predicted for ternary mixture of methane-ethane-water. for this purpose, the tangent plane distance (tpd) minimization method was used. first, the calculations were performed for the binary mixtures of methane-water and ethane-water as the gas and liquid phases. the results show that for a binary mixture of th...

Many professional development opportunities offered to serving teachers address potential performance improvements or responses to change that are essentially incremental in nature. However, some challenges and opportunities particularly those relating to new technologies, involve addressing a more discontinuous change process. The Transformative Personal Development (TPD) model is derived from...

The adsorption and dissociation of carbon dioxide on a Ru(0001) single crystal surface was investigated by reflection-absorption infrared spectroscopy (RAIRS) and temperature-programmed desorption (TPD) spectroscopy for CO2 adsorbed at 85 K. RAIRS spectroscopy shows that the adsorption of CO2 on a Ru(0001) single crystal is partially dissociative, resulting in CO2 and CO. The CO vibrational mod...
