The density of states, thus, obtained is used to estimate variation in Tc from McMillanu2019s formula. These results are in good agreement with experimental data. Calculations of the energy bands are also presented for the low temperature $Pabar{3}$ structure....
High entropy alloys (HEAs) were first reported in the early 2000s. High mixing entropy of the HEAs makes it present good thermal stability. Meanwhile, the large lattice distortion in the HEAs leads to significant solution strengthening. Additionally, clu
the composition surface will be irregular, the twin axis will be perpendicular to a lattice plane...
crystallographic distortions can greatly reduce the symmetry. Ideal perovskites have the empirical formula, ABO3, wherein the A cation occupies a cubic close packed site (thus is coordinated to 12 oxygen atoms), while the B cation occupies an octahedral hole in the close packed structure. ...
U.S. 4,469,589 generalizes these teachings and lists a vast array of compositions with the spinel lattice structure, leading one perhaps to believe that it is the spinel lattice itself which is essential to SOx transfer. Indeed it was well known that FCC catalysts containing generous amounts ...
(hcp) lattice of titanium.These sites are octahedral center (OC) site,hexahedral center (HE) site,and Ti Ti bond center crowdion (CR) site with interstitial energies of-2.83,-1.61,and-1.48 eV,respectively.From the interstitial energies it follows that oxygen atom prefers to occupy the ...
