L. Pósa et al: A Rational Fabrication Method for Low Switching-Temperature VO2
…published in MDPI Nanomaterials (link) by the Nanosensors Group in cooperation with other MFA teams Here, we propose and optimize a simple fabrication method for VO2 rich layers by the oxidation of metallic vanadium in atmospheric air. It was shown that a sufficiently broad annealing time window of 3.0–3.5 h can be obtained at an optimal oxidation temperature of 400 °C. [...]
N. Q. Khánh et al: The effect of substrate bias on the piezoelectric properties of pulse DC magnetron sputtered AlN thin films
We have shown by Piezoresponse Force Microscopy (PFM) that the quality of the deposited AlN layer depends strongly on the negative substrate bias, i.e., the energy transferred via the bombardment of the accelerated positive ions on the sample.

Tire sensor tests on kick-plate track
Nanosensors Group performed several tire sensor tests in collaboration with the Institute for Computer Science and Control (SzTAKI). If you are interested in our driving assistance tire sensor concept please contact our group (contact at nems dot hu).
Dose rate mapping measurement at the KFKI Campus using the DoziMobile unit
In the frame of the DoziNet project it was demonstrated that the radiation detector system developed by the Space Research Laboratory for sounding rocket experiments could be combined with the communication units and protocol used and developed by the Nanosensors Department for self-organizing scalable networks and that the combined system could be integrated into the network of Geiger–Müller (GM) probes installed and operated by the Environmental Protection Service [...]
