The elastic properties of rutile transition metal dioxides XO$_{2}$ (X=Ru, Rh, Os, and Ir) are investigated using first-principles calculations based on density functional theory. Elastic constants, bulk modulus, shear modulus, and Youngs modulus as well as Possion ratio are given. OsO$_2$ and IrO$_2$ show strong incompressibility. The hardness estimated for these dioxides shows that they are not superhard solids. The obtained Debye temperatures are comparative to those of transition metal dinitrides or diborides.
The kinetics of hydrogen absorption by magnesium bulk is affected by two main activated processes: the dissociation of the H$_2$ molecule and the diffusion of atomic H into the bulk. In order to have fast absorption kinetics both activated processed
We investigated the electronic structures of the two-dimensional layered perovskite Sr$_{2}$textit{M}O$_{4}$ (textit{M}=4textit{d} Ru, 4textit{d} Rh, and 5textit{d} Ir) using optical spectroscopy and polarization-dependent O 1textit{s} x-ray absorpti
We report thermoelectric properties of Ir$_{1-x}$Rh$_x$Te$_2$ ($0 leqslant x leqslant 0.3$) alloy series where superconductivity at low temperatures emerges as the high-temperature structural transition ($T_s$) is suppressed. The isovalent ionic subs
Magneto-optical Kerr effect, normally found in magnetic materials with nonzero magnetization such as ferromagnets and ferrimagnets, has been known for more than a century. Here, using first-principles density functional theory, we demonstrate large m
We performed systematic studies of the combined effects of annealing/quenching temperature ({itshape T}$_{A/Q}$) and T = Ni, Rh substitution ({itshape x}) on the physical properties of Ca(Fe$_{1-x}$T$_{x}$)$_{2}$As$_{2}$. We constructed two-dimension
