The main objective of the Concerted Action is to develop new sensing technologies for Air Quality Control at integrated and multidisciplinary scale by coordinated research on nanomaterials, sensor-systems, air-quality modelling and standardised methods for supporting environmental sustainability with a special focus on Small and Medium Enterprises. This international Networking, coordinated by ENEA (Italy), includes over 75 big institutions from 27 COST Countries (EU-zone: Belgium, Bulgaria, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Israel, Italy, Latvia, The Former Yugoslav Republic of Macedonia, Netherlands, Norway, Poland, Portugal, Romania, Serbi...

Especially the dynamic effects are gas dependent and can be used for gas identification. The addition of ultraviolet light reduces internal electrical relaxation effects, but also introduces new, temperature-dependent effects.

This operating mode, studied intensively for semiconductor gas sensors, is applied for the first time with gas sensors based on the field effect. A suitable T-cycle for detection of typical

The chip was packaged in a low temperature co-fired ceramic (LTCC) module with a flip chip bonding technique. A microcontroller operates the chip, while the whole measurement system was controlled by PC. The developed biosensor was applied for measurement of the proliferation stage of adherent cells where the sensor response depends on the ratio between healthy, viable and multiplying cells, which adhere onto the chip surface, and necrotic or apoptotic cells, which detach from the chip surface. This change in cellular adhesion caused a change in the effective permittivity in the vicinity of the sensor element, which was sensed as a change in oscillation frequency of the ring oscillator. The sensor was tested with human lung epithelial cells (BEAS-2B) during cell addition, proliferation and migration, and fin...

The performance was studied for temperatures ranging from 50°C to 400°C and for exhaust speeds up to 10m/s. It also presents the design and basic concepts. The performance study and design development was performed with finite element analysis

The crystal structure and symmetry of the deposited films were studied with X-ray diffraction and Raman spectroscopy, respectively. The film microstructure was also studied with atomic force microscopy and scanning electron microscopy. The thin film crystal structures varied between almost pure V2O5 phase and another phase, suggested being V7O16, generally found in samples composed of nanotubes and identified as VOx-NT. The measured optical transmission spectra of the films also supported the existence of two different phases. The electrical resistivity of the films as a function of temperature behaved like in a typical semiconductor. The gas sensing properties of the films were characterized for different NOx, CO and H2 concentrations. The results showed a response to NOx and H2, which varied from oxidative to reducing according to the film composition and gas background environment. Only very small response was seen towards CO.
