  • Engineering Heterostructured Nanomaterials for Nanoelectronic and Biomedical Applications 
    LUPAN, Oleg (Universitatea Tehnică a Moldovei, 2023)
    Engineering heterostructured nanomaterials for nanoelectronics, as well as for biomedical applications have attracted huge attention in the past decade. It is because heterostructured nanomaterials are constructed by two ...
  • Gamma Radiation Sensitization of ZnO/Al2O3 Sensors Based on Nanoheterostructures 
    LUPAN, Cristian; BÎRNAZ, Adrian; BUZDUGAN, Artur; MAGARIU, Nicolae; LUPAN, Oleg (Springer Nature Switzerland, 2023)
    A study of the influence of gamma radiation on the electrical and sensing properties of ZnO/Al2O3 core@shell heterostructure has been carried out in this work. Using as radiation source Cs-137, a low level of ionizing ...
  • MOF-Coated 3D-Printed ZnO Tetrapods as a Two-in-One Sensor for H2 Sensing and UV Detection 
    CHAKRABORTY, Barnika; SCHADTE, Philipp; POSCHMANN, Mirjam P. M.; LUPAN, Cristian; ZADOROJNEAC, Tudor; MAGARIU, Nicolae; PADUNNAPPATTU, Ajay; SCHÜTT, Fabian; LUPAN, Oleg; SIEBERT, Leonard; STOCK, Norbert; ADELUNG, Rainer (Springer Nature Switzerland, 2023)
    The various applications of hydrogen in the energy sector require sensor materials that can efficiently detect small amounts of H2 in gas mixtures. One solution is the use of a Metal-organic Framework (MOF)-functionalized ...
  • Morphological and Sensing Properties of the ZnO-Zn2SnO4 Ternary Phase Nanorod Arrays 
    LITRA, Dinu; LUPAN, Cristian; TJARDTS, Tim; QIU, Haoyi; ZADOROJNEAC, Tudor; MALAI, Dominic; SEREACOV, Alexandr; AKTAS, Cenk; SIEBERT, Leonard; LUPAN, Oleg (Springer Nature Switzerland, 2023)
    In this paper, the morphological and sensing properties of the Sn-doped ZnO-Zn2SnO4 nanorods obtained by the hydrothermal method are presented. The developed methodology exhibits high levels of efficiency and cost-effectiveness, ...
  • Nanocomposites and Polymer Thin Films: from Gas Phase Synthesis to Functional Applications 
    SCHRÖDER, Stefan; VAHL, Alexander; VEZIROGLU, Salih; LUPAN, Oleg; AKTAS, Cenk; STRUNSKUS, Thomas; FAUPEL, Franz (Universitatea Tehnică a Moldovei, 2023)
    Among the functional nanocomposites, our group has focused on highly filled particulate metal-dielectric nanocomposites films due to their unique functional properties with hosts of applications. To explore collective ...
  • 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 ...
  • Photodetector Based on β-Ga2O3 Nanowires on GaSxSe1-X Solid Solution Substrate 
    SPRINCEAN, Veaceslav; CARAMAN, Mihail; QIU, Haoyi; TJARDTS, Tim; SEREACOV, Alexandr; AKTAS, Cenk; ADELUNG, Rainer; LUPAN, Oleg (Springer Nature Switzerland, 2023)
    The detection of radiation in the ultraviolet C (UVC) region (100–280 nm) is of great importance for numerous technical applications, such as fire detection in security devices, tracking astronomical missile trajectories, ...
