Electrode polarization at the Au, O2(g)/yttria stabilized zirconia interface. Part II: electrochemical measurements and analysis [PDF]
, 1991 The impedance of the Au, O2 (g) / yttria stabilized zirconia interface has been measured as function of the overpotential, temperature and oxygen partial pressure. At large cathodic overpotentials (η < −0.1 V) and large anodic overpotentials (η > +0.1 V)

Photoacoustic Imaging in Oxygen Detection
Applied Sciences, 2017 Oxygen level, including blood oxygen saturation (sO2) and tissue oxygen partial pressure (pO2), are crucial physiological parameters in life science. This paper reviews the importance of these two parameters and the detection methods for them, focusing ...

Preparation and Properties of SnO2 Film Deposited by Magnetron Sputtering
International Journal of Photoenergy, 2012 Tin oxide SnO2 films were prepared by RF magnetron sputtering. The effects of oxygen partial pressure percentage on the SnO2 property have been investigated to obtain relatively high-resistivity SnO2 films which could be used as buffer layers to optimize

Effective Oxygen Partial Pressure during HIP
Journal of the Ceramic Society of Japan, 1990 SrTiO3 ceramics were reduced both by HIP and by Ar-O2 mixed gas at 1300°C. The degree of reduction of the specimens was characterized by optical transmittance and electric conductivity. The degree of reduction of the HIPed specimens were depended on the HIP pressure. The degree of reduction was low at high pressure, but high at low pressure. The degree
