In the present work we demonstrate that C-doped Zr$_{5}$Pt$_{3}$ is an electron-phonon superconductor (with critical temperature T$_\mathrm{C}$ = 3.7\,K) with a nonsymmorphic topological Dirac nodal-line semimetal state, which we report here for the

Twelve different compositions of the ternary Nb–Ni–Si system were synthesized and heat-treated at 1073 K for up to 1000 h. The microstructure of the samples were analyzed using Scanning Electron Microscopy, Energy Dispersive X-ray Spectroscopy an

Transition metal dichalcogenides (TMDs) usually show simple structures, however, with interesting properties. Recently some TMDs have been pointed out as type-II Dirac semimetals. In the present work, we investigate the physical properties of a new c

In the present work, we investigated the electronic and elastic properties in equilibrium and under strain of the type-II Dirac semimetal NiTe$_2$ using density functional theory (DFT). Our results demonstrate the tunability of Dirac nodes' energy an

Boron and Silicon site occupancies of the T2 phase in the Cr–Si–B system were investigated experimentally and by first-principles electronic-structure calculations. A sample with nominal composition Cr 0.625 B 0.175 Si 0.2 was arc-melted under ar

The main goal of the present reassessment is to update the thermodynamic description of the Ni–In (Nickel–Indium) binary system using experimental and ab-initio data from the literature, following the Compound Energy Formalism (CEF) within the sc

The molar heat capacities of the Fe2Nb and Fe7Nb6 intermetallic compounds are reported here for the first time. The results were obtained via Differential Scanning Calorimetry (DSC) measurements, performed in a temperature range between 348 and 1038

In the present work, the Al–Nb–V ternary system was thermodynamically modeled using the compound energy formalism (CEF) within the framework of the CALPHAD method and supported by ab initio calculations, which we report here for the first time. T

We report for the first time the occurrence of superconductivity in the quaternary silicide carbide YRe2SiC with Tc = 5.9 K. The emergence of superconductivity was confirmed by means of magnetic susceptibility, electrical resistivity, and heat capaci

The Pb–Bi (Lead–Bismuth) binary system has gained some prominence in recent years due to the possible use of eutectic alloys as primary-circuit coolant in generation IV nuclear reactors. Apart from the terminal solid solutions A1-Pb and A7-Bi, th
