AB  - In order to establish the influence of the preparation method on thermal behaviour of gels obtained by the sol-gel and microwave-assisted sol-gel methods, a comparative thermal analysis study was conducted by the thermogravimetric and differential thermal analysis (TG/DTG/DTA) and evolved gas analysis (EGA) on TiO2 and V2O5-doped TiO2 gels, where TiO2:V2O5 molar ratio was set to 99.95:0.05 and 98.0:2.0. In contrast to TiO2 gels, for which the thermal behaviour was not significantly influenced by the preparation method, the microwave-irradiated binary samples showed a more complex and prolonged decomposition compared to their non-irradiated counterparts. This observation was correlated with influence of microwaves in enhancing the reaction rate between the Ti and V reagents leading to formation of more complex compositions of gels. Based on TG/DTG/DTA results, the temperatures of 300 and 450 A degrees C were chosen for the processing of powders in air. All samples thermally treated at 300 and 450 A degrees C crystallized in a single anatase phase except the TiO2:V2O5 with a molar ratio 99.95:0.05, obtained by microwave-assisted sol-gel method that contains also small amount of rutile phase. At 550 A degrees C all samples contain mixture of anatase and rutile phases.

AB  - In this work, we prepared zinc stannate (ZTO) thin films by RF sputtering starting from a sintered ceramic target with Zn:Sn ratio 2:1, by varying the argon/oxygen pressures during the deposition process. Thin films were deposited on alumina substrates at 400 degrees C, and subsequently annealed at 600 degrees C in the air. The transparency typical for the as-deposited films was preserved even after their annealing at 600 degrees C in the air, where the high temperature was crucial for the improvement of the crystalline Zn2SnO4 , ZTO phase, as confirmed by Raman measurements. Additionally, the post-deposition thermal treatment resulted in porous ZTO films suitable for gas sensing application. The structural and surface morphological properties of thin films were investigated by Raman spectroscopy, field emission scanning electron microscopy (FE-SEM) and energy dispersive X-ray analysis (EDX). Finally, the gas sensing properties towards nitrogen dioxide, ethanol and acetone have been tested, showing the high potentiality of this material as the gas sensor for ethanol and acetone at 400 degrees C, and nitrogen dioxide at 200 degrees C.

AB  - The influence of the fraction of the glass-fiber (EGF) reinforcement, from 0 to 15 wt%, on the thermal properties of the polymer-matrix composites with the CaCO3 mineral filler is studied. The proper ratio of glass-fibers and mineral filler is important for obtaining good mechanical, and at the same time good thermal properties of the composites used in production of high-quality components in electro industry. For this purpose, the thermal stability and the thermal properties of the fiber-reinforced composites are determined from a set of different characterization techniques and linked with the microstructural changes induced by the different fiber content. The composites are stable upon heating to 260 degrees C, and undergo thermal oxidation between 280 and 560 degrees C, as found by thermogravimetric and differential thermal analysis. The specific heat capacity, C-p, of the composites slightly increases with increasing EGF content for 0 to 10 wt% EGF, with respective values 0.899 J/gK and 0.903 J/gK at 20 degrees C. Slightly lower Cp values of the composite with 15 wt% EGF could be related to a non-uniform distribution of EGF and presence of voids evidenced by scanning electron microscopy. Thermal conductivity of the composites decreases with increasing EGF content from 0.960(6) W/mK to 0.878(2) W/mK for 0 and 15 wt% EGF, respectively.

AB  - In this study we deposited new, ternary thin films of copper aluminum oxide with p-type and n-type behavior using RF magnetron sputtering for use as chemical gas sensors. p-Type materials are known to be good catalysts and can be combined with the well-known n-type materials for chemiresistive sensors application. Copper aluminum oxide in the delafossite phase CuAlO2 is a ternary oxide that has generated interest as a transparent p-type conducting material, while in the spinel phase CuAl2O4 is known to be n-type. We demonstrated that thin films of copper aluminum oxide with the proper resistance can be successfully applied as p-and n-type resistive gas sensors for ozone detection. We have studied the sputtering deposition conditions from a CuAlO2 sintered target by changing the substrate temperature in inert Ar atmosphere. In addition, post-deposition annealing in O-2 atmospheres was also tested. XRD, SEM and Raman investigations were used to characterize the thin films. Selected films with mixed phases of CuAlO2, CuAl2O4 and CuO were tested for gas sensing as resistive chemical sensors, showing promising results with ozone, acetone and ethanol.

AB  - Barium titanate ceramics were prepared using the nanopowder resulting from a polymeric precursor method, a type of modified Pechini process. The obtained nanopowder was observed to agglomerate and in order to de-agglomerate the powder and enhance the properties of the barium titanate the material was attrition milled. The impact of this attrition milling on the electrical properties of the barium titanate was analysed. The temperature dependence of the relative dielectric permittivity showed three structural phase transitions that are characteristic for ferroelectric barium titanate ceramics. The relative dielectric permittivity at the Curie temperature was higher for the attrition-treated sample than for the non-treated barium titanate. The dielectric losses were below 0.04 in both barium titanate ceramics. The grain and grain-boundary contributions to the total resistivity were observed using impedance analyses for both ceramics. A well-defined ferroelectric hysteresis loop and piezoelectric coefficient d(33) = 150 pC/N were obtained for the ceramics prepared from the de-agglomerated powder. In this way we were able to demonstrate that by attrition milling of chemically obtained powders the ferroelectric and piezoelectric properties of the ceramics could be enhanced.
