  • Application of Nano-Oxide Films on the Surfaces of Parts Made of Titanium Alloys in Order to Increase Their Corrosion Resistance 
    TOPALA, P.; OJEGOV, A.; STOICEV, P. (Tehnica UTM, 2015)
    The paper presents the results of nano-scale oxide films formation on sample surfaces made of titanium alloys that is material with a wide application in medicine and biomedicine. It was demonstrated that by the action of ...
  • Effect of Dopant on Selectivity of CuO Nanostructured Films – Based Sensors 
    CRETU, V.; POSTICA, V.; ABABII, N.; MAGARIU, N.; SONTEA, V.; SCHÜTT, F.; ADELUNG, R.; LUPAN, O. (Tehnica UTM, 2015)
    In this work, the effect of different dopants on selectivity performance of gas sensor structures based on CuO nano-structured films that were synthesized from aqueous chemical solutions SCS is reported.
  • Influence of Fe catalyst Morphology on the Growing of Carbon Nanotubes 
    BĂRA, A.; BANCIU, C.; MARINESCU, V.; MORARI, C.; PĂTROI, D. (Tehnica UTM, 2015)
    This study investigates the influence of Fe catalysts on the growing of carbon nanotubes (CNTs) by chemical vapour deposition (CVD) method on different types of substrates. The catalyst film was deposited on the silicon, ...
  • Sensing Properties of Ultra-Thin TiO2 Nanostructured Films Based Sensors 
    POSTICA, V.; REIMER, T.; LAZARI, E.; ABABII, N.; SHISHIYANU, S.; RAILEAN, S.; KAIDAS, V.; KAPS, S.; LUPAN, O.; BENECKE, W.; ADELUNG, R. (Tehnica UTM, 2015)
    In this work, ultra-thin TiO2 nanostructured films, synthesized by atomic layer deposition method (ALD), were integrated in sensor structures. The effect of post-growth annealing and thickness of TiO2 samples on UV and ...
  • UV effect on NO2 Sensing Properties of Nanocrystalline In2O3 
    ILIN, A.; FANTINA, N.; MARTYSHOV, M.; FORSH, E.; FORSH, P.; KASHKAROV, P. (Tehnica UTM, 2015)
    Nanocrystalline indium oxide films with extremely small grains in range of 7 to 40 nm were prepared by sol-gel method. The influence of grain size on the sensitivity of indium oxide to nitrogen dioxide in low concentration ...
  • XRD and XPS of Cd2SnO4 Thin Films Obtained by Spray Pyrolysis 
    POTLOG, T.; BOTNARIUC, V.; RAEVSCHI, S.; DOBROMIR, M.; LUCA, D. (Tehnica UTM, 2015)
    Cd2SnO4 thin films with a 1:1 and 1:3 Sn/Cd weight ratio at different substrate temperatures were fabricated by spray pyrolysis. The structural and surface composition of these films by X-ray diffraction (XRD) and X-ray ...
