Thermochemical and Mechanical Stabilities of the Oxide Scale of 1SiC and Oxygen …
II. Thermochemical and Mechanical Stability Analysis of the Oxide Scale ZrB 21SiC has a complex scale structure containing at least two condensed phases: ZrO 2(c), which in this section is assumed to be a highly porous skeleton with percolating holes, and a
Alloys of Tantalum
Zirconium alloys can be heated to whiteness without undergoing oxidation. Sodium, potassium, mercury and silver do not alloy with tantalum even at high temperatures; attempts to prepare alloys with arsenic, antimony, lead, zinc and tellurium have also failed, but the formation of an alloy with silver, copper and tin for making a dental amalgam with mercury has recently been claimed.
US20030143436A1 - Carbon barrier controlled metal …
The invention provides for oxidatively resistant silicon carbide coated carbon/carbon composites, a method for the preparation of these materials, and their use in high temperature appliions, preferably in brakes for airplanes. The silicon carbide coated C/C
Molybdenum | Plansee
The temperature, alloying elements, impurities and defects of the respective material strongly influence the specific electrical resistivity. Our high performance materials molybdenum and tungsten show a very low specific electrical resistivity: appr. 0.05 Ωmm²/m at room temperature and even less then 0,5 Ωmm²/m at a temperature of 1,500 °C.
Modulation of nitrogen vacancy charge state and …
The nitrogen vacancy center (NV) in diamond is a fluorescent color center that can be in several charge states depending on its local electrostatic environment. Here, we demonstrate the control of the charge state and fluorescence of NVs in nanodiamonds (NDs) by applying a potential difference across NDs in an electrochemical cell. Controlling the charge state can improve spin-based sensing

An In-Situ TEM Study on the Formation of Gold Carbide - Ulm
Silicon (Fig. 3c), nitrogen, and oxygen (Fig. 3d) as constituents can be excluded as the local EELS signals do not show any corresponding In-Situ TEM Study on the Formation of Gold Carbide 67
Oxygen | O2(2−) - PubChem
Oxygen therapy increases the arterial pressure of oxygen and is effective in improving gas exchange and oxygen delivery to tissues, provided that there are functional alveolar units. Oxygen plays a critical role as an electron acceptor during oxidative phosphorylation in the electron transport chain through activation of cytochrome c oxidase (terminal enzyme of the electron transport chain).
