Advanced Electronic Materials, EarlyView.An investigation of the orbital Hall effect and the orbital torque in Pt/[Co/Ni]3/Ti multilayers with perpendicular magnetic anisotropy. A notable effective field per unit current density of orbital torque is achieved, nearing 560 Oe per 107 A cm−2. The orbital torque generated by Ti layer can effectively switch the perpendicularly magnetized moments ...

International Journal for Numerical Methods in Fluids, Volume 95, Issue 1, Page 107-142, January 2023., 2023 In this article, a novel mass and momentum conservative semi‐implicit finite volume scheme is developed for the coupled solution of hydrostatic shallow water flow and the movement of one or more floating rigid bodies. The coupling is achieved via a nonlinear volume function in the mass conservation equation that depends on the coordinates of the ...

Enhancing Thermoelectric Performance of Cd₃P₂ by Alloying with Dirac Material Cd₃As₂
Advanced Electronic Materials, EarlyView.This study demonstrates that alloying Cd₃P₂ with Dirac material Cd₃As₂ significantly enhances its thermoelectric performance. Key improvements include increased carrier mobility, reduced effective mass, and lower deformation potential, resulting in a doubled power factor and improved thermoelectric efficiency, which renders this material applicable for

International Journal for Numerical Methods in Fluids, Volume 95, Issue 1, Page 143-175, January 2023., 2023 We present a new strong‐form meshless solver combined with the boundary condition‐enforced immersed boundary method for the numerical solution of the nonstationary, incompressible, viscous Navier–Stokes equations in their stream function‐vorticity (in 2D) and vector potential‐vorticity (in 3D) formulation.

The Cauchy problem for a linear parabolic partial differential equation
Journal of Mathematical Analysis and Applications, 1979 AbstractNumerical approximation of the solution of the Cauchy problem for the linear parabolic partial differential equation is considered. The problem: (p(x)ux)x − q(x)u = p(x)ut, 0 < x < 1,0 < t⩽ T; u(0, t) = ƒ1(t), 0 < t ⩽ T; u(1,t) = ƒ2(t), 0 < t ⩽ T; p(0) ux(0, t) = g(t), 0 < t0 ⩽ t ⩽ T, is ill-posed in the sense of Hadamard.
