Effects of point defects on oxidation of 3C-SiC [PDF]

, 2021
The influence of implantation-induced point defects (PDs) on SiC oxidation is investigated via molecular dynamics simulations. PDs generally increase the oxidation rate of crystalline grains. Particularly, accelerations caused by Si antisites and vacancies are comparable, and followed by Si interstitials, which are higher than those by C antisites and ...

Effect of Vanadium Thickness and Deposition Temperature on VO2 Synthesis using Atmospheric Pressure Thermal Oxidation [PDF]

Thin Solid Films 724, 138630 (2021), 2021
Vanadium dioxide (VO2) is a phase transition material that undergoes a reversible insulator-metal phase transition at ~ 68 C. Atmospheric pressure thermal oxidation (APTO) of vanadium (V) is a simple VO2 synthesis method in which V thin film is oxidized in open air.

Paraoxonase 1, HDL Subclasses and Post Surgery Acute Inflammation: A Pilot Study

Antioxidants, 2019
High density lipoproteins (HDL) structure and function studies are needed to better understand the heterogeneous nature of the HDL particle, and its interaction with associated proteins such as apolipoprotein A-1 (ApoA-1), paraoxonase 1 (PON1) and the ...

Higher Hepcidin Levels in Adolescents with Obesity Are Associated with Metabolic Syndrome Dyslipidemia and Visceral Fat

Antioxidants, 2021
Tightly regulated iron metabolism prevents oxidative stress. Hepcidin is a hormone that regulates iron flow in plasma; its production is induced by an iron overload and by inflammation.

Sr flux stability against oxidation in oxide-MBE environment: flux, geometry, and pressure dependence [PDF]

Y.S. Kim et al. J. Vac. Sci. Technol. A 28, 271 (2010), 2011
Maintaining stable fluxes for multiple source elements is a challenging task when the source materials have significantly different oxygen affinities in a complex-oxide molecular-beam-epitaxy (MBE) environment. Considering that Sr is one of the most easily oxidized and widely used element in various complex oxides, we took Sr as a probe to investigate ...

FK506-Binding Protein 2 Participates in Proinsulin Folding

Biomolecules, 2023
Apart from chaperoning, disulfide bond formation, and downstream processing, the molecular sequence of proinsulin folding is not completely understood. Proinsulin requires proline isomerization for correct folding.

Pressure-Dependent Layer-by-Layer Oxidation of ZrS2(001) Surface [PDF]

arXiv, 2023
Understanding oxidation mechanisms of layered semiconducting transition-metal dichalcogenide (TMDC) is important not only for controlling native oxide formation but also for synthesis of oxide and oxysulfide products. Here, reactive molecular dynamics simulations show that oxygen partial pressure controls not only the ZrS2 oxidation rate but also the ...

Understanding of the Retarded Oxidation Effects in Silicon Nanostructures [PDF]

Applied Physics Letters 100, 26 (2012) 263111, 2012
In-depth understanding of the retarded oxidation phenomenon observed during the oxidation of silicon nanostructures is proposed. The wet thermal oxidation of various silicon nanostructures such as nanobeams, concave/convex nanorings and nanowires exhibits an extremely different and complex behavior.

Competing Atomic and Molecular Mechanisms of Thermal Oxidation [PDF]

Journal of Applied Physics 114, 033522 (2013), 2012
The oxidation of SiC and Si provide a unique opportunity for studying oxidation mechanisms because the product is the same, SiO2. Silicon oxidation follows a linear-parabolic law, with molecular oxygen identified as the oxidant. SiC oxidation obeys the same linear-parabolic law but has different rates and activation energies and exhibits much stronger ...
