Advanced 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.

Advanced 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.

Twisted photonic Weyl meta-crystals and aperiodic Fermi arc scattering
Nature CommunicationsAs a milestone in the exploration of topological physics, Fermi arcs bridging Weyl points have been extensively studied. Weyl points, as are Fermi arcs, are believed to be only stable when preserving translation symmetry.

Discrete Mathematics, 1997 This is a very useful survey (without many proofs) on what is known about the maximum size \(m(r,q)\) of an \(n\)-arc in \(\text{PG}(r,q)\) and the size \(m'(r,q)\) of the second largest complete arc in \(\text{PG}(r,q)\). The connection of \(n\)-arcs in the projective space \(\text{PG}(r,q)\) (that is, a set of \(n\) points no \(r+1\) of which are ...

Advanced 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.

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma
Advanced Engineering Materials, EarlyView.The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

A Full List of Projectively Distinct K-Arcs in Finite Projetive Space Pg(2,8) [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2012 A k-arc in a plane PG(2,q) is a set of k point such that every line in the plane intersect it in at most two points and there is a line intersect it in exactly two points. A k-arc is complete if there is no k+1-arc containing it.
