One-step preparation of the BiVO4 film photoelectrode

25 de abril de 2019 LAbI UFSCar 0

One-step preparation of the BiVO4 film photoelectrode Abstract:  A one-step method of preparing photoelectrochemically active nanostructured BiVO4 films is reported based on thermolysis (500 A degrees C in air) of a polyethylene glycol (PEG300) “paint-on” precursor […]

Ozone gas sensor based on nanocrystalline SrTi1-xFexO3 thin films

5 de novembro de 2018 LAbI UFSCar 0

Ozone gas sensor based on nanocrystalline SrTi1-xFexO3 thin films Abstract: We report on the use of nanocrystalline SrTi1−xFexO3 (STF) for sensing ozone gas. Amorphous thin films were evaporated by the electron-beam physical vapor deposition technique and then converted to a polycrystalline form, as […]
