Gas Sensor Arrays by Supersonic Cluster Beam Deposition

Barborini E., Leccardi M., Bertolini G., Rorato O., Franchi M., Bandiera D., Gatelli M., Wegner K., Raso A., Garibbo A., Ducati C., Piseri P., Milani P., Tethis S.r.l., IT

Supersonic cluster beam deposition was employed to produce nanostructured thin films of transition metal oxides to be used as gas sensors. The cluster beam was generated by a pulsed microplasma cluster source equipped with aerodynamic [...]

Integrated Gas-Phase Manufacturing of Nanostructured Particulate Films

Wegner K., Piseri P., Bongiorno G., Vinati S., Pratsinis S.E., Milani P., Tethis S.r.l., IT

An integrated process for controlled one-step production of nanostructured particulate thin films is presented, combining gas-phase nanoparticle synthesis, aerodynamic particle manipulation, size selection and deposition. Such films find industrial application for instance in fuel cells, [...]

First-Principles Studies of SnS2 Nanotubes

Chang H., In E., Kong K-J, Lee J-O, Choi Y., Ryu B-H, Korea Research Institute of Chemical Technology, KR

First principles calculations are used to predict the stability and electronic structures of SnS2 nanotubes. Optimization of several structures and their corresponding strain energies confirms the stability of SnS2 nanotube structures. Band structure calculations show [...]

Thermal Management of Micro-Hotplates using MEMCAD as Simulation Tool

Briand D., Grétillat M.-A., van der Schoot B., de Rooij N.F., Institute of Microtechnology, CH

In this paper we report on the electrothermal simulations performed in the aim of optimising the power consumption and the temperature distribution of micro-hotplates for gas sensing applications. The micro-hotplate designs were optimised using the [...]
