The influence of gas-phase oxygen on the growth of Au nanoparticles on Mo-doped CaO films has been investigated by means of low temperature scanning tunnelling microscopy and X-ray photoelectron spectroscopy. Whereas at ideal vacuum conditions, only 2D Au islands develop on the oxide surface, the fraction of 3D deposits increases with increasing O2 pressure until they become the dominant specie...

Due to the shortcomings of AgSnO2 as a contact material, models SnO2, Y-SnO2, Mo-SnO2, and Y-Mo-SnO2 were built calculate their electrical mechanical properties based on first principles density functional theory. The Y-Mo co-doped SnO2 was most stable all according enthalpy change impurity formation energy. By analyzing energy band structure states, it shown that doped are still direct bandgap...

Smirniotis). High temperature water gas shift reaction (WGS) at low steam to CO ratios has been investigated over Fe2.4Ce0.3M0.3O4 (M = Cr, Co, Zr, Hf, and Mo) type of spinels in the temperature region of ...

Fe-based catalysts doped with Mo were prepared and tested in the catalytic decomposition of methane (CDM), which aims for the co-production of CO2-free hydrogen and tubular nanostructured carbon (NC). Catalysts performance were tested in a thermobalance operating either at isothermal or temperature programmed mode by monitoring the weight changes with time or temperature, respectively, as a res...

This work presents the emergence of superconductivity in Ir - doped Weyl semimetal T$_d$ MoTe$_{2}$ with broken inversion symmetry. Chiral anomaly induced planar Hall effect and anisotropic magneto-resistance confirm topological semimetallic nature Mo$_{1-x}$Ir$_{x}$Te$_{2}$. Observation weak anisotropic, moderately coupled type-II -Mo$_{1-x}$Ir$_{x}$Te$_{2}$ makes it a promising candidate for ...

In order to improve photocatalytic activities of the pure anatase TiO2 under UV and visible light irradiations, a novel and efficient N-doped TiO2 photocatalyst was prepared by sol-gel method. N-doped titania is prepared using the various nitrogen sources such as: triethylamine, N,N,N’,N’-tetramethylethane-1,2-diamine, ethyldiamine, 1,2-phenylenediamine, propanolamine, and...
