Hydrogen storage is one of the attractive research interests in recent years due to advantages hydrogen be used as energy source. The studies on applications focus mainly investigation capabilities newly introduced compounds. present paper aims at characterization CaXH3 (X: Mn, Fe, or Co) perovskite-type hydrides for first time understand their potential contribution applications. compounds have been investigated by density functional theory reveal various characteristics and properties....
Temperature dependence of the upper critical field Hc2 (T) for superconducting magnesium diboride, MgB2, is studied in vicinity Tc by using a two-band Ginzburg-Landau (G-L) theory. The temperature near exhibits positive curvature. In addition, calculated and its higher order derivatives are also shown to be good agreement with experimental data. analogy multi-band character Eliashberg microscopic theory, curvature described reasonably solving G-L
The structural, electronic, mechanic, vibrational and thermodynamic properties of Ti2SiB which is a hypothetical MAX phase compound, have been investigated using density functional theory calculations. structural optimization has performed the results compared with Ti2SiC, Ti2SiN, Ti2AlB that are studied in literature. Then band structure corresponding partial states computed. In addition, charge Bader analysis performed. elastic constants obtained, then secondary such as bulk modulus, shear...
The temperature dependence of the lower critical field Hc1(T) for superconducting magnesium diboride, MgB2, is studied in vicinity Tc using a two-band Ginzburg–Landau (G–L) theory. theoretically calculated near exhibits negative curvature. results are shown to be good agreement with experimental data. In addition, G–L theory calculations give parameter κ (T) = λ (T)/ξ (T), which varies little manner similar microscopic single-band BSC
The half-Heusler TiRhSb and ZrRhSb alloys in the formation of face-centered cubic MgAgAs-type structure, which conforms to space group with 216 as number, have been investigated using Generalized Gradient Approximation (GGA) implemented Density Functional Theory (DFT). calculated enthalpies plotted energy-volume curves different types structural phases (α, β, γ) these indicate that γ-phase structure is best energetically suitable structure. In addition, found paramagnetic (PM) investigation...
The doping effect of hydrogen on the Ca3CHx (x = 1, 4, 7, 9, and 10) antiperovskite compounds has been examined using density functional theory (DFT). results structural optimizations show that all these have negative formation energy implying energetic stability synthesizability. band structures are essential for electronic properties determined along with partial states (DOS) showing metallic behavior compounds. In addition, electron-density distribution determined, charge each ion in...
In this study, the Li5AuP2 compound is investigated in detail due to unique chemical properties of gold that are different from other metals. Pressure applied 0 25 GPa reveal its structural, mechanical, electronic, and dynamical using density functional theory (DFT). Within pressure range, optimized with a tetragonal crystal structure, making it mechanically dynamically stable above 18 resulting an increment bulk, shear, Young's moduli Li5AuP2. application, furthermore, changes brittle or...
Abstract In this study, the NiMo 6 Se 8 Chevrel phase is analyzed using Density Functional Theory (DFT) and Vienna Ab‐initio Simulation Package (VASP). The analysis focuses on phase's structural, electrical, mechanical characteristics to fill gaps in current literature. presence of a rhombohedral crystal structure confirms its thermodynamic stability, as indicated by negative formation enthalpy, which suggests that it can be synthesized under favorable conditions. electronic properties are...

The magnetic response of Bi-based superconductors nominal composition against low AC field amplitudes is studied in terms fundamental and third harmonic susceptibilities to investigate various physical parameters. Optimum conditions a wet preparation technique have been determined. Both transport inductive critical current densities increased considerably on samples subjected single intermediate grinding. data accompanied by XRD measurements support the theory that minor superconducting...
