Introduction: Mössbauer spectrometers will be used on martian landers and rovers to identify and quantify relative amounts of Fe-bearing minerals, as well as to determine their Fe/Fe ratios, allowing more realistic modeling of martian mineralogy and evolution. However, derivation of mineral modes, Fe/Fe ratios, and phase identification via Mössbauer spectroscopy (MS) does have limitations. We d...

Up to now many heavy hadrons have been discovered experimentally. Their inner structures and interactions attract much attention. Some of them are speculated to be possible new hadron states beyond the traditional quark model. For example, the newly discovered Zb states are treated as the B̄ (∗)B∗ molecular states [1, 2]. Many other molecular states, such as those composed of ΞcΞc, DD̄ ∗, are als...

Fe–As based superconductors provide a good system for understanding the relationship between magnetism and superconductivity. Considerable efforts have been expended in understanding the magnetic behavior of the parent compound, BaFe2As2. However, it had not been realized that traces of adsorbed O2 by the material bring about drastic changes in its magnetic behavior. O2 is known to trap electro...

In a 331 model in which the lepton masses arise from a scalar sextet it is possible to break spontaneously a global symmetry implying in a pseudoscalar majoron-like Goldstone boson. This majoron does not mix with any other scalar fields and for this reason it does not couple, at the tree level, neither to the charged leptons nor to the quarks. Moreover, its interaction with neutrinos is diagona...

A two phase microstructure, consisting of nanocrystallites surrounded by an amorphous matrix, was produced by a melt spinning processing route. Alloys of this type have extrinsic properties that are dependent on the relative amounts of the amorphous and nanocrystalline phases. One method for examination of the properties of the nanocrystalline and amorphous phases is by Mössbauer spectroscopy. ...

SU(3) gauge theory with dynamical overlap fermions in the 2-index symmetric (sextet) representation is considered. This model may be a viable model of the electroweak symmetry breaking sector along the lines of the walking technicolor paradigm. The number of fermion species is chosen such that the theory is expected to be below the conformal window. We will discuss how the ε-regime and random m...

Abstract Tons of waste is produced during iron steel’s industrial production, creating environmental pollution. This work aims to characterize the steel scale formed on billet surface last step production in SIDERPERU plant. Scanning Electron Microscopy (SEM) shows stacked layers one above other billets scales surface. Energy Dispersive X-ray (EDX) and Fluorescence (XRF) reveal high content Fe ...
