Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

Enhanced magnetization in Y substituted Bi0.94Sm0.06FeO3 multiferroic ceramics

open access: yesKuwait Journal of Science, 2020
The compounds Bi0.94Sm0.06FeO3, Bi0.92Sm0.06Y0.02FeO3, Bi0.90Sm0.06Y0.04FeO3, and Bi0.88Sm0.06Y0.06FeO3 were found to have the rhombohedral perovskite-like structure. The structural parameters were extracted from the X-ray diffraction data.

Polaron Problems in Ultracold Atoms: Role of a Fermi Sea across Different Spatial Dimensions and Quantum Fluctuations of a Bose Medium

open access: yesAtoms, 2021
The notion of a polaron, originally introduced in the context of electrons in ionic lattices, helps us to understand how a quantum impurity behaves when being immersed in and interacting with a many-body background.

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Hypotension in patients administered indigo carmine containing impurities -A case report- [PDF]

open access: yesKorean Journal of Anesthesiology, 2011
Indigo carmine has been used for eight decades with few adverse effects. Several of our patients, however, experienced severe hypotensive episodes after indigo carmine administration within a period of one month.

Impurity Behavior in Plasma Recovery after a Vacuum Failure in the Experimental Advanced Superconducting Tokamak

open access: yesApplied Sciences, 2023
After a vacuum failure in a tokamak, plasma runaway or plasma disruptions frequently occur during plasma recovery, causing difficulties in rebuilding a well-confined collisional plasma.

Dielectric screening in two-dimensional insulators: Implications for excitonic and impurity states in graphane [PDF]

open access: yes, 2011
For atomic thin layer insulating materials we provide an exact analytic form of the two-dimensional (2D) screened potential. In contrast to three-dimensional systems where the macroscopic screening can be described by a static dielectric constant, in 2D ...

Influence of Sample Preparation and Processing Procedures on the Thermal Diffusivity of MgO‐C Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

Antibunching Effects in the Hybrid Cavity–Bose–Einstein Condensates System

open access: yesPhotonics, 2023
We theoretically study the model of a hybrid cavity–Bose–Einstein condensates (BEC) system that consists of a two-level impurity atom coupled to a cavity–BEC system with radiation pressure coupling, where the system is weakly driven by a monochromatic ...
