AB  - The oxide mixtures xCuO-(1-x) MoO3 were synthesized by gel-combustion procedure. The existence of phase mixture CuO + Cu3Mo2O9 and MoO3 + CuMoO4 in CuO-rich and MoO3 -rich composition region, respectively, were evidenced. The constant heating rate thermogravimetry in hydrogen atmosphere revealed that the reduction reactions proceed within the two clearly separated temperature regions. On the basis of mass changes, the mechanism of reduction processes was discussed. The measurements revealed considerable inhibition of CuO reduction by MoO3, and huge acceleration of MoO3 → MoO2 reduction step by copper. The particularities found in this system were commented in relation to our similar studies in NiO-MoO3 and CuO-WO3 systems. For particular composition, x = 0.5, existing preferably in form of a-CuMoO4, kinetic parameters of reduction were determined. The composition of oxide mixture influenced the particle size and morphology of resulting metallic Cu-Mo composites.

AB  - Cathodic material for sodium-ion rechargeable batteries based on NaxMnO2 were synthesized by glycine nitrate method and subsequent annealing at high temperatures. Different crystal structures with different morphologies were obtained depending on the annealing temperature: hexagonal layeredα-Na0.7MnO2.05 nanoplates were obtained at 850 °C, while 3-D tunnel structured Na0·4MnO2 and Na0·44MnO2, both with rod-like morphology, were obtained at 800 °C and 900 °C, respectively. The investigations of the electrochemical behavior of obtained cathodic materials in aqueous NaNO3 solution have shown that Na0·44MnO2 obtained at 900 °C has shown the best battery performance. Its initial discharge capacities are 123.5 mA h/g, 113.2 mA h/g, and 102.0 mA h/g at the high current densities of 1000, 2000 and 5000 mA/g, respectively.

AB  - Radar-absorbent materials, used in stealth technology for defense aircrafts, vehicles, satellites, etc. from radar detection, are commonly based on graphite or semiconductive particles embedded in a polymer matrix. In this study, we employed Co2+ ion-substitution to improve Vis-NIR reflectivity of hydroxyapatite (Ca10(PO4)6(OH)2, HAP) powder. HAP:Co with nominally 5 at.% of Co was prepared with hydrothermal processing of a precipitate. Synthesized powder was characterized by XRD, Raman and ATR-FTIR spectroscopy, FE-SEM and TEM. Thermal stability of HAP:Co powder was examined by simultaneous TG-DTA analyzer. To modify its optical properties and obtain powders with a varietty of color tone, the HAP:Co powder was calcined at 800, 1000, and 1100 °C, in an air atmosphere, for 1 hour. Afterward, the calcined particles were used to prepare composites with poly(vinyl butyral), (PVB); the concentration range was 1 wt.% of the HAP:Co in PVB. The composite coatings, in the form of thin films on glass, were prepared by the solvent-casting technique, using ethanol as a fast evaporating solvent. Firstly, the HAP:Co particles were dispersed in ethanol, then PVB was added (Mowital B30H) and dissolved. To evaporate the solvent before spectrophotometric measurements, the coatings on glass were dried at room temperature for 72 hours. To comprehend optical properties of the coatings, diffuse reflection, transmission, and color coordinates were determined. We found that calcined HAP:Co particles have potential to be used in the formulation of coatings for camouflage protection.
