  • Synthesis and chemical gas sensing properties of WO3 nanomaterials 
    GALSTYAN, Vardan; BORSI, Matteo; D'ARCO, Annalisa; LUPI, Stefano; COMINI, Elisabetta (Technical University of Moldova, 2022)
    Herein, we report a novel synthesis method for the fabrication of WO3 nanostructures. We performed the synthesis of nanomaterials by the thermal treatment of tungsten thin films using sodium chloride and distilled water. ...
  • Thin films of copper oxide nanostructured via rapid thermal processing 
    CRETU, Vasilii; LUPAN, Cristian; MANCIU, Nicolae; ABABII, Nicolai; POSTICA, Vasile; RAILEAN, Serghei; GALSTYAN, Vardan; CHOW, Lee; PAUPORTÉ, Thierry (Technical University of Moldova, 2021)
    The temperature dependent gas sensing properties of nanostructured copper oxide nanolayers obtained by the method of chemical synthesis from solutions (SCS) and exposed to postgrowth rapid thermal processing (RTP) in air ...
  • Thin films of copper oxide nanostructured via rapid thermal processing 
    LUPAN, Cristian; CREȚU, Vasilii; MISHRA, Abhishek Kumar; MAGARIU, Nicolae; MANCIU, Nicolae; ABABII, Nicolai; MISHRA, Soni; RAILEAN, Serghei; ZIMOCH, Lukas; GALSTYAN, Vardan; HANSEN, Sandra; PAUPORTÉ, Thierry (Technical University of Moldova, 2022)
    Nanostructured copper oxide films were obtained by the method of chemical synthesis from solutions (SCS) and exposed to post-growth rapid thermal processing (RTP) in air at different temperatures to study the influence of ...
  • TiO2 nanotubes for chemical sensing 
    GALSTYAN, Vardan; POLI, Nicola; COMINI, Elisabetta (Technical University of Moldova, 2021)
    The importance of high performance gas sensing devices is rapidly increasing for a wide range of applications, including detection of toxic and explosive compounds in public spaces, military facilities, and chemical ...
  • TiO2/Cu2O/CuO Multi-Nanolayers as Sensors for H2 and VOCs: An Experimental and Theoretical Investigation 
    LUPAN, Oleg; SANTOS-CARBALLAL, David; ABABII, Nicolai; MAGARIU, Nicolae; HANSEN, Sandra; VAHL, Alexander; ZIMOCH, Lukas; HOPPE, Mathias; PAUPORTE, Thierry; GALSTYAN, Vardan; SONTEA, Victor; CHOW, Lee; FAUPEL, Franz; ADELUNG, Rainer; LEEUW de, Nora H.; COMIN, Elisabetta (American Chemical Society, 2021)
    Highly sensitive TiO2/Cu2O/CuO multi-nanolayers have been grown in various thicknesses by a cost-effective and reproducible combined spray-sputtering-annealing approach. The ultra-thin TiO2 films were deposited by spray ...
  • TiO2/Cu2O/CuO Multi-Nanolayers as Sensors for H2 and Volatile Organic Compounds: An Experimental and Theoretical Investigation 
    LUPAN, Oleg; SANTOS-CARBALLAL, David; ABABII, Nicolai; MAGARIU, Nicolae; HANSEN, Sandra; VAHL, Alexander; ZIMOCH, Lukas; HOPPE, Mathias; PAUPORTÉ, Thierry; GALSTYAN, Vardan; SONTEA, Victor; CHOW, Lee; FAUPEL, Franz; ADELUNG, Rainer; de LEEUW, Nora H.; COMINI, Elisabetta (American Chemical Society, 2021)
    TiO2/Cu2O/CuO multi-nanolayers highly sensitive toward volatile organic compounds (VOCs) and H2 have been grown in various thicknesses by a cost-effective and reproducible combined spray–sputtering–annealing approach. The ...
