Deposition of porous nano-WO3 coatings with tunable grain shapes by liquid plasma spraying for gas-sensing applications

Comparison between Suspension Plasma Sprayed and High Velocity Suspension Flame Sprayed bioactive coatings

“…Due to such flexibility, the SPS technique has already been proposed for a large variety of functional applications, including the manufacturing of gas-sensing layers [60], of solid oxide fuel cells [61], and of thermal barrier coatings [62]. The latter example also shows an instance where porous SPS coatings prove to be advantageous over denser HVSFS ones, because of better compliance (resulting in enhanced thermal shock resistance) and lower thermal conductivity.…”

Nanowires-assembled WO3 nanomesh for fast detection of ppb-level NO2 at low temperature

“…Many techniques have been used to synthesize WO 3 in various forms and investigate the effect of morphology on their gas-sensing performance. Various morphologies of WO 3 , such as nanofibers, nanoflowers, and nanoplates, have been prepared by a variety of methods including electrospinning, thermal evaporation, and hydrothermal and plasma spraying [23][24][25][26][27]. Compared to other synthetic techniques, hydrothermal method is more advantageous due to low-temperature synthesis and ease of mass production [28][29][30][31][32].…”

Effects of a polystyrene intermediate layer for improved electrochromic properties of nano porous WO3 electrochromic films

“…Electrochromic WO 3 has application as rearview mirrors, automobile glazing, smart sunglasses, and smart windows. [4][5][6] Since the first reported work on the electrochromism of WO 3 , 7 this material has been continuously researched for improving its properties, understanding its physics and developing devices using WO 3 . 6,[8][9][10] In general, there are interstitial sites in WO 3 where foreign materials or ions can be inserted easily to change the behaviour of the EC material.…”
