Effect of nano yttria stabilized zirconia on corrosion behaviour of chromium oxide coatings on boiler steel

open access: yesJournal of Electrochemical Science and Engineering, 2023
In this research work, 5 wt.% nano yttria-stabilized zirconia (YSZ) reinforced chromium oxide-based nanocomposite coatings were prepared and successfully deposited on ASME-SA213-T-22 (T22) boiler tube steel substrates using high-velocity oxyfuel (HVOF ...

Nuclear structure of superheavy nuclei - state of the art and perspectives (@ S3)

open access: yesEPJ Web of Conferences, 2018
Decay spectroscopy is a powerful tool to study the low lying nuclear structure of heavy and superheavy nuclei (SHN). Single particle levels and other structure features like K isomerism, being important in the fermium-nobelium region as well as for the ...

Ejecta Transfer in the Pluto System [PDF]

open access: yes, 2014
The small satellites of the Pluto system (Styx, Nix, Kerberos, and Hydra) have very low surface escape velocities, and impacts should therefore eject a large amount of material from their surfaces. We show that most of this material then escapes from the

The Least Luminous Galaxy: Spectroscopy of the Milky Way Satellite Segue 1 [PDF]

open access: yes, 2008
We present Keck/DEIMOS spectroscopy of Segue 1, an ultra-low luminosity (M_V = -1.5) Milky Way satellite companion. While the combined size and luminosity of Segue 1 are consistent with either a globular cluster or a dwarf galaxy, we present ...

Development of Sustainable Alkali-Activated Mortars Using Fe-Rich Fayalitic Slag as the Sole Solid Precursor

open access: yesFrontiers in Built Environment, 2021
Vast amounts of water-cooled non-ferrous metallurgy slags are generated yearly, and significant amounts are unutilized or dumped in landfills. To address this issue, in this study, MgO-FeOx-SiO2 fayalitic slag (FS) was used as the sole solid precursor ...

Path-Length-Resolved Dynamic Light Scattering: Modeling the Transition From Single to Diffusive Scattering [PDF]

open access: yes, 2000
Dynamic light-scattering spectroscopy is used to study Brownian motion within highly scattering samples. The fluctuations of the light field that is backscattered by a suspension of polystyrene microspheres are measured as power spectra by use of low ...
