Resistive Switching of GaAs Oxide Nanostructures [PDF]

Materials, 2020
The paper presents the results of experimental studies of the influence of the local anodic oxidation control parameters on the geometric parameters of oxide nanoscale structures (ONS) and profiled nanoscale structures (PNS) on the surface of epitaxial structures of silicon doped gallium arsenide with an impurity concentration of 5 × 1017 cm−3.

HfB2-doped ZrB2-30 vol.% SiC composites: oxidation resistance behavior

Materials Research Express, 2021
To investigate the HfB _2 on microstructure and oxidation resistance of ZrB _2 -30 vol% SiC, ZrB _2 -30 vol% SiC composites with different amounts of HfB _2 (4, 8, and 12 vol%) were consolidated by Spark Plasma Sintering method (SPS).

Silicon based oxidation-resistant coatings on Ti6242 alloy by dynamic ion mixing [PDF]

, 2006
The influence of SixCy and SixNy amorphous coatings on the oxidation resistance of a Ti6242 (Ti–6Al–2Sn–4Zr–2Mo) alloy was investigated. They were produced at room temperature by the dynamic ion mixing technique combining physical vapour deposition with ...

Nonlinear Oxidation Behavior in Pure Ni and Ni-Containing Entropic Alloys

Frontiers in Materials, 2018
We performed a combined experimental and theoretical investigation of the oxidation behavior of pure Ni and of the following multi-component Ni-containing alloys with nearly equiatomic compositions: FeNi, CoFeNi, CoCrFeNi, and CoCrFeMnNi.

Mechanism of Resistance to Oxidative Stress in Doxorubicin Resistant Cells.

Biological and Pharmaceutical Bulletin, 2001
Doxorubicin (DOX) is an anthracycline drug widely used in chemotherapy for cancer patients, but it often gives rise to multidrug resistance in cancer cells. The purpose of this work was to study the effect of hydrogen peroxide in DOX-sensitive mouse P388/S leukemia cells and in the DOX-resistant cell line.

Microstructural evolution and high-temperature oxidation resistance of laser-modified AlCoCrFeNi(YHf) high-entropy alloy at 1200 °C

Journal of Materials Research and Technology
The Y/Hf-doped equiatomic AlCoCrFeNi high-entropy alloy (HEA) shows good oxidation resistance but suffers from Al depletion and oxide layer spallation during long-term exposure at 1200 °C.

Comparative study of high temperature oxidation behaviour in AISI 304 and AISI 439 stainless steels

Materials Research, 2003
This work deals with a comparison of high temperature oxidation behaviour in AISI 304 austenitic and AISI 439 ferritic stainless steels. The oxidation experiments were performed between 850 and 950 °C, in oxygen and Ar (100 vpm H2). In most cases, it

Physiological increases in uncoupling protein 3 augment fatty acid oxidation and decrease reactive oxygen species production without uncoupling respiration in muscle cells

, 2005
Decreased uncoupling protein (UCP)3 is associated with insulin resistance in muscle of pre-diabetic and diabetic individuals, but the function of UCP3 remains unclear.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
