The spin injection and accumulation in metallic lateral spin valves with transparent interfaces are studied using dc injection current. Unlike ac-based techniques, this allows the investigation of the effects of the direction and magnitude of the injected current. We find that the spin accumulation is reversed by changing the direction of the injected current, whereas its magnitude does not cha...

We study thermodynamics and phase transitions of magnetically charged by nonlinear electrodynamics (NED) Anti-de Sitter (AdS) black holes in an extended space. The cosmological constant is treated as a thermodynamic pressure whereas the hole mass considered such chemical enthalpy. horizon shows analogy with Van der Walls liquid–gas system. define quantities which are conjugated to parameter NED...

This paper studies thermodynamics of magnetically charged black holes in Anti-de Sitter space an extended phase space. The cosmological constant is considered as a pressure and the hole mass treated chemical enthalpy. similar to Van der Walls liquid–gas thermodynamics. Quantities conjugated nonlinear electrodynamics parameter magnetic charge are obtained. first law generalized Smarr relation ta...

Herein, the application of Carnahan-Starling-vdW-β equation of state (EoS) for 13 refrigerant fluids was investigated. The EoS could predict the saturated liquid densities of these refrigerants over the temperature range of 100-400 K and pressures from zero up to187 MPa with the average absolute deviations of 2.66%. The accuracy of Carnahan-Starling-vdW-β EoS in liquid density prediction was al...
