TL;DR: In this paper, multiwalled carbon nanotube (MWCNT) films have been fabricated by using plasmaenhanced chemical vapor deposition system onto Cr-Au patterned alumina substrates, provided with 3nm thick Fe growth catalyst, for NO2 and NH3 gas sensing applications, at sensor temperature in the range of 100-250°C.

TL;DR: In this paper, the impact of the tailored load of gold (Au) nanoclusters functionalizing the sidewalls of the carbon nanotubes (CNTs) networks on gas sensing performance of a chemiresistor, operating at a working temperature in the range of 20-250°C.

TL;DR: In this paper, a gas chemiresistor, fabricated onto alumina using multi-walled carbon nanotubes (MWCNTs) networked films grown by radiofrequency plasma enhanced chemical vapor deposition (RF-PECVD) technology, is described for high-performance gas detection, at an operating temperature of 200°C.

TL;DR: The metal-decorated and vertically aligned CNT sensor array is able to discriminate the NO(2) presence in the multicomponent mixture LFG and the recovery mechanisms in the CNT chemiresistors can be altered by a rapid heating pulse from room temperature to about 110 degrees C.

TL;DR: In this paper, laser damage resistance studies have been performed at 308nm (XeCl laser) by the photoacoustic beam deflection technique, on hafnium dioxide (HfO2) thin films deposited on fused silica substrates either by the ion-assisted electron beam evaporation technique or by a dual-ion-beam sputtering technique.
