TL;DR: The structural, mechanical, electronic and magnetic properties of the series of Heusler alloys CoFeMnZ (Z=Si, As, and Sb) have been investigated theoretically as discussed by the authors.

TL;DR: In this article, a numerical investigation was made for heat transfer and steady magneto-hydrodynamic natural convection in a fined cold wavy-walled porous enclosure with a hot elliptic inner cylinder occupied by hybrid Fe3O4-MWCNT /water nanofluid.

TL;DR: The results of using natural fibers for 3D Printing are presented and appeared to be satisfactory, while a few studies have reported some issues.

TL;DR: In this article, the electronic structures and magnetic properties of K2O and Rb2O alloys doped simultaneously with Cr and V transition elements were investigated using the full-potential linearized augmented plane wave plus local orbital (FP-LAPW + lo) method within the spin-polarized density functional theory (Spin-DFT) and implemented in the WIEN2k package, where the exchange-correlation potential in this approach is described by the generalized gradient approximation with Coulomb repulsion (GGA + U).

TL;DR: In this article, the optimum crystallization parameters for reducing crystal defects in Cu2Zn1−xCdxSnS4 quaternary alloy nanostructures were investigated. And the analytical results confirmed a multi-phase polycrystallinity of the samples, and the variations in their energetic transitions and optical properties with Cd content were investigated, also observed.
