Theoretical Study of Decomposition of Methanediol in Aqueous Solution

14.05.2015 | Satoshi Inaba, Journal of Physical Chemistry A, 2015

Methanediol is a product of the hydration of formaldehyde and is more abundant than formaldehyde in aqueous solution. We carried out a number of quantum chemical simulations to study the decomposition of methanediol in aqueous solution. The decomposition of a methanediol proceeds by transferring ...

Insights into the gas phase oxidation of Ru(0001) on the mesoscopic scale using molecular oxygen

14.05.2015 | Jan C. Goritzka; Benjamin Herd; Philipp P. T. Krause; Jens Falta; J. Ingo Flege; Herbert Over, Physical Chemistry Chemical Physics, 2015

We present an extensive mesoscale study of the initial gas phase oxidation of Ru(0001), employing in situ low-energy electron microscopy (LEEM), micro low-energy electron diffraction (μ-LEED) and scanning tunneling microscopy (STM). The initial oxidation was investigated in a temperature range of ...

Hot‐wire vapor deposition of amorphous MoS2 thin films

13.05.2015 | Georgios Papadimitropoulos, Nikolaos Vourdas, A. Kontos, Maria Vasilopoulou, Dimitrios N. Kouvatsos, Nicolas Boukos, ..., physica status solidi (c), 2015

Abstract Amorphous, as shown by X‐ray diffraction measurements, MoS2 films (a‐MoS2) were deposited by heating a molybdenum wire at temperatures between 500 and 700 °C in H2S at 1 Torr. As shown by Scanning Electron Microscopy measurements, the morphology of samples depends significantly on the ...

2H-CuScO2 Prepared by Low-Temperature Hydrothermal Methods and Post-Annealing Effects on Optical and Photoelectrochemical Properties

13.05.2015 | Thomas I. Draskovic; Mingzhe Yu; Yiying Wu, Inorganic Chemistry, 2015

The delafossite structured CuScO2 is a p-type, wide band gap oxide that has been shown to support significant oxygen intercalation, leading to darkened color and increased conductivity. Control of this oxidation proves difficult by the conventional high-temperature solid-state syntheses. In ...

Cobalt‐iron oxides made by CVD for low temperature catalytic application

12.05.2015 | Patrick Mountapmbeme Kouotou, Zhen‐Yu Tian, physica status solidi (a), 2015

Thin films of cobalt‐iron oxides (CoFe2O4) with spinel‐type structure were prepared by pulsed‐spray evaporation chemical vapor deposition (PSE‐CVD) using Fe(acac)3 and Co(acac)3 as precursors. The optimal depositions of CVD‐type growth have been established and such growth can be achieved at ...

About dislocation and oxygen related luminescence of Si around 0.8 eV

11.05.2015 | M. Kittler, T. Arguirov, M. Reiche, C. Krause, D. Mankovics, physica status solidi (c), 2015

Abstract In conjunction with the two‐level model the temperature behaviour of the dislocation‐related D1‐peak follows the T‐behaviour of the band gap. Based on luminescence observations in our laboratory and on literature data we propose a ∼30 meV wide domain of the D1 peak. Altogether, the ...

Energies, Vol. 8, Pages 4216-4236: 3-D CFD Modeling for Parametric Study in a 300-MWe One-Stage Oxygen-Blown Entrained-Bed Coal Gasifier

11.05.2015 | Park, Sang Shin; Jeong, Hyo Jae; Hwang, Jungho, Energies, 2015

Three-dimensional computational fluid dynamics (CFD) modeling of the gasification performance in a one-stage, entrained-bed coal gasifier (Shell Coal Gasification Process (SCGP) gasifier) was performed, for the first time. The parametric study used various O2/coal and steam/coal ratios, and the ...
