CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishSensing of typical gaseous pollutants and malodors as a result of decomposition of organic compounds via chemoresistive gas sensors has been addressed. Screen-printed films of a solid solution of mixed Sn and Ti oxides, of mixed W and Sn oxides, and ZnO have been selected for the purpose. We demonstrated that the choice of these films for this specific use leads to an improvement in selective detection of such gases under either dry or wet condition. An array of such sensors is shown to be suitable for implementation of deconvolution algorithms because it makes it easier the concentration data processing.
