Nanocrystalline porous Cu films were prepared on glass subtrates by sol-gel spin coating technique with copper(II) acetate as raw material and NH(C2H2OH)2as chelating agent. The characteristics of films were analyzed by IR, TG-DTG, XRD and SEM. The structure of Cu films was remarkable influenced by sol concentration and PEG content. The effects of calcining temperature and the way of the gelation on grain size were discussed. The results showed that the pore size and density are homogeneous when the sol concentration was 0.6 mol/L and the PEG content was 0.35 g.

Abstract This study deals with the synthesis of some physical properties of (CdO/NiO) nanocomposite via Sol-Gel method and their antibacterial activities. The NiO and CdO nanoxides as well as the CdO/NiO oxide mixture were prepared in five samples with different concentrations where the ratio of CdO/NiO was [(1: 0), (3: 1), (1: 1), (1: 3), (0: 1)], by using the gel solution by means of a polyvinyl alcohol solution ( PVA ). The samples were platelimb at (500̊C) for three hours. The structural properties of the prepared oxides resulting from the cracking process were studied. The XRD results showed the presence of pure cadmium oxide diffraction patterns in the sample (S 1 ) as well as pure nickel oxide in the sample (S 5 ), and confirmed the presence of the CdO / NiO oxide mixture in the samples (S 2 , S 3 , S 4 ). The results of XRD also showed, through calculations, that the specific surface area increased with increasing granular size and decreased with decreasing granular size. XRD calculations also showed that the intensity of eruptions decreased as the granular volume increased and, inversely, increased with decreasing granular size.

<p>Pure phase Li<sub>2</sub>TiO<sub>3 </sub>nano-particles were synthesized by the sol-gel method and the structural properties were examined with X-ray diffraction (XRD) technique. The latter showed that these materials, heat treated at relatively low temperature 900°C during 4h compared to the conventional solid-state reaction which calcination temperature is about 900–1100°C for 10 h; crystallize in the monoclinic phase without the presence of secondary phases. The microstructure of the LT ceramic (sintered at 1100°C) were determined by SEM and a good crystalline nature was observed with an average of granular size 2 μm. Moreover, the impedance spectroscopy showed at a higher temperature of 500°C the low-frequency arc due either to the grain boundary or sample-electrode charge transport processes.</p>
