  • Microheaters for copper oxide based gas sensors 
    TROFIM, Viorel; ABABII, Nicolai; LUPAN, Oleg (Tehnica UTM, 2019)
    In recent years, gas sensors based on oxide semiconductors such as copper oxide [1], have a very high development progress, as their market demands are high for the detection of toxic and flammable gases, as well as their ...
  • A New Approach in Detection of Biomarker 2-propanol with PTFE-Coated TiO2 Nanostructured Films 
    SCHRÖDER, Stefan; BRINZA, Mihai; CRETU, Vasile; ZIMOCH, Lukas; GRONENBERG, Monja; ABABII, Nicolai; RAILEAN, Serghei; STRUNSKUS, Thomas; PAUPORTE, Thierry; ADELUNG, Rainer; FAUPEL, Franz; LUPAN, Oleg (Springer Nature Switzerland, 2023)
    Certain molecules act as biomarkers in exhaled breath or outgassing vapors of biological systems. Metal oxide gas sensors are of great interest to detect these molecules. However, often they are not selective enough to ...
  • Pd-doped ZnO nanostructured films for multifunctional applications 
    POSTICA, Vasile; HOPPE, Mathias; ADELUNG, Rainer; PAUPORTÉ, Thierry; ABABII, Nicolai; TROFIM, Viorel; SONTEA, Victor; LUPAN, Oleg (Technical University of Moldova, 2017)
    In this work Pd-doped ZnO (ZnO:Pd) nanostructured films were deposited on pre-cleaned glass substrates via a synthesis from chemical solutions (SCS) approach from aqueous baths. The post-rowth thermal annealing, namely ...
  • Porous materials for electrical gas sensors and actuators without moveable part 
    ADELUNG, Rainer (Technical University of Moldova, 2022)
    This talk briefly summarizes the work of our group over the last decade, showing how highly porous materials can be used as both electrical sensors and electrical actuators without the need for moving parts. This is because ...
  • The Reliability to Gamma Radiation of Gas Sensors Based on Nanostructured ZnO:Eu 
    LUPAN, Cristian; BÎRNAZ, Adrian; BUZDUGAN, Artur; ZIMOCH, Lukas; ADELUNG, Rainer; LUPAN, Oleg (Technical University of Moldova, 2022)
    In this work it was investigated the reliability to ionizing radiation of Eu-doped ZnO nanostructured films functionalized with Pd. Morphological, sensorial and electrical properties of sensors were studied initially, after ...
  • 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 ...
  • Sensitivity investigation to formaldehyde of the vapors of nanostructured films from ZnO semiconductor oxides for medical application 
    LUPAN, Oleg; POCAZNOI, Ion; ABABII, Nicolai; CRETU, Vasilii; SECU, Iuliana (Tehnica UTM, 2019)
    Formaldehyde (СH2О) of 40% is widely used in medicine as a substance applied in processes for sterilization of bone grafts for further use as implants. The efficiency of sterilization depends on the amount of СH2О remaining ...
  • 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 ...
