Enhanced ethanol vapour sensing performances of copper oxide nanocrystals with mixed phases

LUPAN, Oleg; CRETU, Vasilii; POSTICA, Vasile; ABABII, Nicolai; POLONSKYI, Oleksandr; KAIDAS, Victor; SCHÜTT, Fabian; MISHRA, Yogendra K.; MONAICO, Eduard; TIGINYANU, Ion; SONTEA, Victor; STRUNSKUS, Thomas; FAUPEL, Franz; ADELUNG, Rainer (ELSEVIER, 2016)

The present study reports on nano-crystalline copper oxide thin films via a simple synthesis from chemical solutions (SCS) followed by two types of thermal annealing, namely rapid thermal annealing (RTA) and conventional ...
Localized Synthesis of Iron Oxide Nanowires and Fabrication of High Performance Nanosensors Based on a Single Fe2O3 Nanowire

LUPAN, Oleg; POSTICA, Vasile; WOLFF, Niklas; POLONSKYI, Oleksandr; DUPPEL, Viola; KAIDAS, Victor; LAZARI, Eugen; ABABII, Nicolai; FAUPEL, Franz; KIENLE, Lorenz; ADELUNG, Rainer (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2017)

A composed morphology of iron oxide microstructures covered with very thin nanowires (NWs) with diameter of 15–50 nm has been presented. By oxidizing metallic Fe microparticles at 255 °C for 12 and 24 h, dense iron oxide ...
Multifunctional device based on ZnO:Fe nanostructured films with enhanced UV and ultra-fast ethanol vapour sensing

POSTICA, Vasile; HÖLKEN, Iris; SCHNEIDER, Viktor; KAIDAS, Victor; POLONSKYI, Oleksandr; CRETU, Vasilii; TIGINYANU, Ion; FAUPEL, Franz; ADELUNG, Rainer; LUPAN, Oleg (ELSEVIER, 2016)

Extensive application requests on high-performance gas sensors and photodetectors reveal the importance of controlling semiconducting oxide properties. Sensing properties of ZnO nano- and micro-structures can be tuned and ...
Non-planar nanoscale p–p heterojunctions formation in ZnxCu1−xOy nanocrystals by mixed phases for enhanced sensors

LUPAN, Oleg; CRETU, Vasilii; POSTICA, Vasile; POLONSKYI, Oleksandr; ABABII, Nicolai; SCHÜTT, Fabian; KAIDAS, Victor; FAUPEL, Franz; ADELUNG, Rainer (ELSEVIER, 2016)

The copper oxides are advanced materials due to their remarkable sensing, optical, electrical, thermal and magnetic performances. Nanostructuring and doping of copper oxides enhance further the possible features of these ...
Three-dimensional flexible ceramics based on interconnected network of highly porous pure and metal alloyed ZnO tetrapods

GRÖTTRUP, Jorit; PAULOWICZ, Ingo; SCHUCHARDT, Arnim; KAIDAS, Victor; KAPS, Sören; LUPAN, Oleg; ADELUNG, Rainer; MISHRA, Yogendra Kumar (ELSEVIER, 2016)

Flexible and porous three-dimensional (3-D) ceramics made from inorganic metal oxide nano- and micro-structures are going to be material candidates for future nanotechnologies. In the present work an attempt in this direction ...
