Tunable Optical Properties of Amorphous-Like Ga₂O₃ Thin Films Deposited by Electron-Beam Evaporation with Varying Oxygen Partial Pressures

Nanomaterials, 2020
Ga2O3 thin films were fabricated by the electron-beam evaporation technique at a varying oxygen partial pressure from 0 to 2.0 × 10−2 Pa. The effect of oxygen partial pressure on the crystalline structure and optical properties of the Ga2O3 films was ...

Reactive sputtering deposition of SiO2 thin films [PDF]

Journal of the Serbian Chemical Society, 2008
SiO2 layers were deposited in a UHV chamber by 1 keV Ar+ ion sputtering from a high purity silicon target, using different values of the oxygen partial pressure (5×10-6–2×10-4 mbar) and of the ion beam current on the target (1.67–6.85 mA).

Response behaviour of oxygen sensing solid electrolytes [PDF]

, 1985
The response time (t r) after a step change in oxygen partial pressure was investigated for some solid electrolytes used in Nernst type oxygen sensors. The electrolyte as well as the (porous) electrode material affect the value oft r.

AN EXPERIENCE OF SERELAXINE USE FOR ACUTE HEART FAILURE IN PATIENTS WITH ONCOHEMATOLOGICAL DISEASES

Кардиоваскулярная терапия и профилактика, 2015
Treatment of acute heart failure (ACF) remains a strenuous task. Modern treatment methods — diuretics, vasodilators, inotropic drugs — are effective in ACF symptoms reduction, but do not decrease risk of death, that is still very high in this urgent ...

Effects of Oxygen Partial Pressure on 4-Hydroxy-2-Nonenal Induced Oxymyoglobin Oxidation

Meat and Muscle Biology, 2019
4-hydroxyl-2-nonenal (HNE) is a lipid oxidation product that can increase oxymyoglobin oxidation. However, limited research has evaluated the role of oxygen partial pressure in HNE-induced metmyoglobin formation.
