In this contribution, a multilayer resistive sensor based on catalytically activated and non-activated SrTiO 3 is presented as a device for lean hydrocarbon sensing. This set-up should enable a compensation of oxygen cross interference. Whereas the c

Simultaneous Hall and conductivity measurements were performed in situ between 650° and 1050°C on n-type semiconducting BaSnO3ceramics. The variation of the Hall mobility and the Hall carrier density as a function of oxygen partial pressure between

The gas sensitivity of Ga2O3 thin-film n-type conductors was investigated at temperatures of 500–1000°C. Palladium dispersions whose particle sizes are dependent on the preceding annealing processes were deposited by a wet-chemical technique onto

The characteristic NIR-absorption lines of methane and ethane are being acquired simultaneously and their concentrations are determined using a tunable DFB laser diode. This paper reports on the development of a hand-held and low-power sensor, based

It is known that barium carbonate can act as CO2 sensitive material in work function type gas sensors in ambient condition. The reaction is due to the formation of bicarbonate species at the surface. The cross-sensitivity to other acidic gases as NO2

Semiconducting metal-oxide gas sensors are generally nonselective, which limits their use as natural gas detectors in domestic environments when ethanol is present in high background concentrations. Using a thin-film Ga/sub 2/O/sub 3/ sensor with a t

This paper presents an ultrasonic method for measuring the mass density of liquids with a solid layer separating a reference fluid and a test fluid. By adjusting the frequency of the exciting signal according to the thickness of the layer, it is poss

In this work, it was found that exposure of TiN to ammonia (400 ppb–100 ppm) in wet synthetic air at room temperature leads to a reversible decrease of Δ Φ . There is a change of the work function of −30 meV/decade of increasing ammonia concent

This paper presents investigations on DC emission currents from heated surfaces at ambient pressure for the purpose of gas sensing. Since applied gases alter the work function (WF) of a material, the emitted electron current changes and becomes gas s
