Metal oxide nanocrystals for gas sensing
Proceedings of IEEE Sensors, 2004., 2005Quasi-one-dimensional nanostructures (so-called nanobelts or nanowires) of tin dioxide, obtained by vapour phase deposition, have been investigated for gas sensing. The physical quantity for signal transduction could be either electrical conductance or photoluminescence.

An intelligent gas sensing system
Sensors and Actuators B: Chemical, 1997Electrically conducting organic polymers are widely used as a means of gas, odour or aroma analysis using multi-element array techniques coupled with direct current (d.c.) interrogation techniques. Recently it has been established that the use of alternating current (a.c.) interrogation gives rise to improved performance.

Remote sensing of gas emissions on natural gas flares [PDF]
Pure and Applied Optics: Journal of the European Optical Society Part A, 1998 Emissions from operational natural gas flares are examined by a remote sensing technique using a commercial moderate-resolution Fourier-transform infrared spectrometer. The thermal radiation emitted by the post-combustion gas is analysed to determine plume temperatures and concentrations of and .

Soft Sensing for Gas-Lift Wells
Proceedings of SPE Annual Technical Conference and Exhibition, 2004Abstract This paper considers the use of extended Kalman Filtering as a soft-sensing technique for gas-lift wells. This technique is deployed for the estimation of dynamic variables that are not directly measured. Possible applications are the estimation of flow rates from pressure measurements or the estimation of parameters of a drift ...

Oxygen-sensing glomus cells in the carotid body of the carotid artery are responsible for detecting low oxygen levels and for inducing a compensatory increase in respiration rate. However, the molecular mechanism of oxygen sensing in these glomus cells has remained enigmatic.

Gas molecules such as O2, NO, CO and ethylene are present in the environment and are endogenously (enzymatically) produced to act as signalling molecules in biological systems, including the regulation of metabolic networks, chemotaxis, circadian rhythms, mammalian hypoxia responses, and plant ethylene responses by transcriptional, translational, or ...

New properties of SAW gas sensing
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1998Novel attractive properties of SAW gas sensing are theoretically predicted and experimentally verified. The response upon gas exposure of SAW-based gas sensors can be increased, decreased, reversed, cancelled, speeded up, aged down, and selected for a given sensitive layer, simply by changing the substrate material and orientation.
