Combustion Monitor Sensor Based on Tin Dioxide

Methane-assisted combustion synthesis of nanocomposite tin dioxide materials

Combustion synthesis of tin dioxide (SnO2) was studied using a new synthesis approach where the combustion environment was augmented to control the temperature and flow conditions using methane as a supplemental fuel. The experiments were carried out at atmospheric pressure using a multi-element diffusion flame burner with a gas-phase precursor for SnO2 and solid-phase precursor for metal addit...

Nanostructured Tin Dioxide Materials for Gas Sensor Applications

The Effects of Two Thick Film Deposition Methods on Tin Dioxide Gas Sensor Performance

This work demonstrates the variability in performance between SnO(2) thick film gas sensors prepared using two types of film deposition methods. SnO(2) powders were deposited on sensor platforms with and without the use of binders. Three commonly utilized binder recipes were investigated, and a new binder-less deposition procedure was developed and characterized. The binder recipes yielded sens...

Samarium (III) Selective Membrane Sensor Based on Tin (IV) Boratophosphate

A number of Sm (III) selective membranes of varying compositions using tin (IV) boratophosphate as electroactive material were prepared. Polyvinyl chloride, polystyrene and epoxy resin were used as binding materials. Membrane having composition of 40% exchanger and 60% epoxy resin exhibited best performance. This membrane worked well over a wide concentration range of 1x10M to 1x10 M of samariu...

Thermal conductivities of individual tin dioxide nanobelts

We have measured the thermal conductivities of a 53-nm-thick and a 64-nm-thick tin dioxide (SnO2) nanobelt using a microfabricated device in the temperature range of 80–350 K. The thermal conductivities of the nanobelts were found to be significantly lower than the bulk values, and agree with our calculation results using a full dispersion transmission function approach. Comparison between meas...
