A comparative study on the NH
3gas-sensing properties of ZnO, SnO2, and WO3nanowireIn this work, a large quantity of ZnO, SnO2 and WO3 nanowires (NWs) was successfully synthesised by simple and efficient methods. Their morphology and microstructure were characterised by FE-SEM, TEM, XRD, PL, and Raman. The NH3 gas-sensing properties of these NWs were investigated and compared. It was found that the responses and response-recovery time of SnO2 and WO3 NWs sensors to NH3 gas are ...

Atomic cluster device research in New Zealand
We review research in New Zealand on nano-electronic devices fabricated using atomic clusters as building blocks. Techniques described include those based on percolation, and on self (or directed) assembly in templates. The templates used are V-grooves etched into silicon wafers and lithographically defined patterns in PMMA on silicon. Both methods exploit the tendency, which is demonstrated by ...

Improving Indoor Air Quality with Cubic NDIR CO2 Sensor for DCV Systems
Indoor air quality is essential in closed spaces with high occupancy levels. When the indoor CO2 concentration increases, the indoor air quality will be substandard, and occupants will gradually experience physical discomfort if the condition of high CO2 concentration continues. Especially when indoor CO2 concentration exceeds 1000ppm, people will feel uncomfortable. Therefore, a CO2-based DCV ...

Study of defect behaviour in Ga2O3 nanowires and nano-ribbons under reducing gas annealing conditions: applications to sensing
The growth of monoclinic Ga2O3 nanowires, nano-ribbons and nano-sheets has been investigated. Results indicate that high quality single crystal nanowires can be grown at 900?C using an Au catalyst, while single crystal nano-ribbons and nano-sheets require no metal catalyst for growth. Since bulk Ga2O3 is a promising material for high temperature gas sensing, Ga2O3 nanowires and nano-ribbons may ...
