Resumen
In order to improve the photocatalytic efficiency, the N doped anodic titania film for photocatalyst was synthesized by anodic oxidation of TiN layer in sulfuric electrolyte, and the photocatalytic properties of N doped TiO2layer were investigated. During the oxidation process of the TiN layer, nitrogen was doped into the anodic titania film due to the change of the titanium nitride layer to TiO2layer film. In the evaluation of dye degradation, N doped titania catalyst shows much higher efficiency than non-doped titania film.

Resumen
Optical properties of titania thin films supported on silica plates and compounded with varying amounts of Co(II) from cobalt nitrate are reported. The ellipsometric characterization allows to model the spatial micro-structure of these thin film composites. The titania films were produced by the sol-gel method at room temperature and their thicknesses can be controlled by modifying the experimental conditions. The refractive index of the doped titania films was also determined by using ellipsometry.

Resumen
Large crystals of titanium nitride (mineral osbornite) from metallurgical slag were studied by EMPA, XRD and Raman spectroscopy. The sample was collected at metallurgical dump in Kladno in the early 1970s and briefly described by Žáček and Ondruš (2003). The sample has a size of about 40 × 30 × 30 mm and is notable for its high density and conspicuous cubes of copper-like red to gold colour with metallic lustre (Fig. 1–2).

Resumen
Iridium serves as the active electrocatalyst in driving the hydrogen evolution reaction (HER), an important process in water-splitting technology for the production of green hydrogen. However, the expensive cost and limited durability of Ir-based catalysts have hindered the widespread application of HER. Thus, there is research interest in reducing the mass loading of Ir and enhancing long-term stability. In this work, we synthesized highly stable titanium nitride (TiN) to serve as the supporting material for low-loading Ir-Ni alloys (Ir-Ni/TiN) utilized in HER. The TiN was derived from the py
