Context. Collisionally ionized plasmas produce X-ray spectra that depend on electron energy and atomic processes, requiring accurate atomic rate coefficients for modeling. [...]

The limited ductility of laser powder bed fusion (LPBF) Ti-6Al-4V (Ti64) alloys, caused by their brittle α'-martensitic microstructure, significantly restricts their broader application. This study systematically investigates the influence of Mo additions (0, 1, 3, and 5 wt%) on the microstructure evolution, deformation mechanisms, and mechanical properties of LPBF Ti64 alloys.

Superconductors consisting of heavy metals are extensively studied in recent times as these materials having strong spin–orbit coupling may help to realize topological behavior important for next generation technology as well as realizing exotic fundamental scenario. Here, we study the electronic structure of one such exotic superconductor, PdTe employing depth-resolved high resolution photoemission spectroscopy and density functional theory. [...]

First order phase transitions (FOPT) in the early Universe can be powerful emitters of both relativistic and heavy particles, upon the collision of ultra-relativistic bubble shells. If the particles coupling to the bubble wall have CP-violating interactions, the same collision process can also create a local lepton or baryon charge. [...]

Recently, the promising multi-component magnetocaloric materials (Mc-MCMs) are found to have a tunable giant magnetocaloric effect (GMCE) near room-temperature and manifest fruitful functionalities like multi-caloric effects, which are candidates for solid-state caloric applications. Introducing vacancy defects is found to be an efficient method to optimize its GMCE property. [...]

In the present work, the magnetic properties of NiO/CoFe$_2$O$_4$ (CFO) bilayers, grown via pulsed laser deposition on Si (100) substrates, have been investigated. The NiO layer thickness has been varied to explore its effect on the structural, magnetic, and electronic properties of the studied bilayer [...]

B/B′-sites ordering and disordering play a decisive role in determining the magnetic characteristics of the A$_2$BB'O$_6$-types of double perovskites (DPs). Generally, B/Bʹ-site ordered structures promote the B–O–B′ bond (interaction). [...]

This article examines the influence of unintentional Cr3+and Fe3+impurity ions on the luminescent properties of Gd3Ga5O12(GGG) single crystals. The characteristic features of the spectra excited by high-energy syn-chrotron radiation in the temperature range of 10–300 K are analyzed [...]

Electron beam (EB) modification was carried out on the polylactide (PLA) fibers at the temperature both below and above the glass transition temperature (Tg) under nitrogen atmosphere. The irradiation at elevated temperature was performed by using a novel fiber stretching frame setup to protect fibers from shrinking, in which a permanent constant tension was loaded along fiber bundles to maintain their straightness throughout the irradiation. [...]

This study investigates a cost-effective, cobalt-free Al$_{0.5}$CrNi$_{1.5}$Fe$_2$ multi-principal element alloy, based on the most studied AlCoCrFeNi alloy system. The alloy underwent thermal mechanical treatment to induce partial recrystallization, resulting in a multi-phase, multi-scale heterogeneous microstructure. [...]
