DOI: 10.1007/s10948-017-4442-5

Abstract: The thermodynamic properties of the tetragonal RNi2B2C (R=Y, Lu) are investigated by means of the density-functional theory (DFT) and density-functional perturbation theory (DFPT) within the quasiharmonic approximation (QHA). The phonon dispersion curves and phonon total… read more here.

DOI: 10.1063/5.0223322

Abstract: We study the impedance behavior of two ferrofluids, of a similar magnetic material, one constituted by spherical nanoparticles and the other constituted by cubes, both suspended in kerosene. The ferrofluid constituted by cubic nanoparticles has… read more here.

DOI: 10.7567/1882-0786/ab3e5e

Abstract: In this work, we demonstrate a tri-band perfect absorber with the maximal absorptance of 97% achieved in an ultra-thin silicon film metasurface (thickness, 60 nm, ~λ/10). Particularly, the resonant absorption peaks are observed to be… read more here.
