Macrophagic enhancement in optical coherence tomography imaging by means of superparamagnetic iron oxide nanoparticles [PDF]

open access: yes, 2017
Background: The ability of optical coherence tomography (OCT) to visualise macrophages in vivo in coronary arteries is still controversial. We hypothesise that imaging of macrophages in OCT could be enhanced by means of superparamagnetic nanoparticles ...

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

open access: yesY.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 ...

Template-free synthesis of hybrid silica nanoparticle with functionalized mesostructure for efficient methylene blue removal [PDF]

open access: yes, 2021
A simple one-pot synthesis process for functionalized mesostructured silica nanoparticles (MSNP) is reported. The novel process demonstrated the possibility to achieve MSNP with a surface area up to 501 m2.g−1 using a phosphonate based nonsilane ...

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

open access: yesarXiv, 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]

open access: yesApplied 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]

open access: yesJournal 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 ...

Atomistic details of oxide surfaces and surface oxidation: the example of copper and its oxides [PDF]

open access: yesSurface Science Reports 70 (2015) 424-447, 2015
The oxidation and corrosion of metals are fundamental problems in materials science and technology that have been studied using a large variety of experimental and computational techniques. Here we review some of the recent studies that have led to significant advances in our atomic-level understanding of copper oxide, one of the most studied and best ...

Tribology of Ti-6Al-4V Alloy Manufactured by Additive Manufacturing [PDF]

open access: yes, 2020
In this study, the influence of ultrasonic nanocrystal surface modification (UNSM), which was applied as a post-additive manufacturing (AM), in terms of surface, tensile and tribological properties of Ti-6Al-4V alloy by selective laser melting (SLM) was ...
