Oxidation of Platinum Resistance Thermometers

AIP Conference Proceedings, 2003
PRTs were soaked at different temperatures, and the resulting changes caused by oxidation and the subsequent dissociation of the formed oxide were observed. Soaking below 400 °C initiated oxidation, in some platinum resistance thermometers (PRTs), and then their resistance steadily increased with increasing temperatures up to about 525 °C. When soaking

Boric Oxide Deposition on Carbon Nanofibers for Oxidation Resistance

Journal of Nanoscience and Nanotechnology, 2013
The boric oxide deposition was performed to improve the oxidation resistivity of carbon nanofiber (CNF) from electrospinning at elevated temperatures. The stabilized electrospun polyacrylonitrile (PAN) nanofibers were coated with boric oxide, followed by heat treatment up to 1000, 1200, and 1400 degrees C in an inert nitrogen atmosphere.

The resistance to oxidation of an HfB2–SiC composite

Journal of the European Ceramic Society, 2005
The oxidation resistance of an hot-pressed HfB2-–SiC composite was studied through non-isothermal and isothermal treatments at temperatures up to 1600°C in air. The most severe oxidation conditions consisted of repeated heating-cooling cycles at 1600°C for up to 80 min of exposure. A thermogravimetric test for over 20 h at 1450°C provided evidence that,

Oxidation Resistance of Reactive Atoms in Graphene

Nano Letters, 2012
We have found that reactive elements that are normally oxidized at room temperature are present as individual atoms or clusters on and in graphene. Oxygen is present in these samples but it is only detected in the thicker amorphous carbon layers present in the graphene specimens we have examined.

Oxidative Resistance of Na/K-ATPase

Cellular and Molecular Neurobiology, 1999
1. Oxidative modification of Na/K-ATPase from brain and kidney has been studied. Brain enzyme has been found to be more sensitive than kidney enzyme to inhibition by both H2O2 and NaOCl. 2. The inhibition of Na/K-ATPase correlates well with the decrease in a number of SH groups, suggesting that the latter belong mainly to ATPase protein and are ...

Resistive Switching Effect in Titanium Oxides

Journal of Nanoscience and Nanotechnology, 2014
Resistive switching (RS) phenomena have been vigorously investigated in a large variety of materials and highlighted for its preeminent potential for the future nonvolatile semiconductor memory applications or reconfigurable logic circuits. Among the various resistive switching materials, the binary metal oxides demonstrate more advantageous for micro-

Nitric oxide and vascular insulin resistance

BioFactors, 2009
AbstractObesity and type‐II diabetes are growing major health issues worldwide. They are the leading risk factors for vascular insulin resistance, which plays an important role in the pathogenesis of cardiovascular disease, the leading cause of death in developed nations.

Design for Oxidation Resistance

1997
Abstract Alloys intended for use in high-temperature environments rely on the formation of a continuous, compact, slow-growing oxide layer for oxidation, and hot corrosion resistance. This article focuses on the issues related to high-temperature oxidation of superalloys used in gas turbine engine applications.

Versatile resistive switching in niobium oxide

2016 IEEE International Symposium on Circuits and Systems (ISCAS), 2016
Resistive switching devices have a high potential for nonvolatile memories and circuit applications. This paper gives a review of the different switching modes in niobium oxide. Abrupt memory switching, threshold switching with or without memory switching and analog switching can be obtained by controlling the stoichiometry of the layer stack either ...

Protein oxidation in obesity and insulin resistance

European Journal of Pediatrics, 2006
Advanced oxidation protein products (AOPP) are considered reliable markers to estimate the degree of oxidant-mediated protein damage. Data on oxidative stress in childhood obesity and insulin resistance are limited.The aim of this study was to investigate the AOPP level as an oxidative stress marker in obesity and insulin resistance. The study included
