New molecular modeling data show that the entropy of bcc iron exhibits no system-size anomalies, implying that it should be feasible to compute accurate free energies of this system using first-principles methods without requiring a prohibitively large number of atoms. Conclusions are based on rigoro...
Biotransformation of Flavonoids with -NO2, -CH3 Groups and -Br, -Cl Atoms by Entomopathogenic Filamentous Fungi. Int. J. Mol. Sci. 2023, 24, 9500. https://doi.org/ 10.3390/ijms24119500 Academic Editor: Fucheng Lin Received: 2 May 2023 Revised: 24 May 2023 Accepted: 27 May 2023 ...
We trace these bands to pockets of electron density arising between sterically encumbered ammonias, six such pockets in the Z = 8 unit cell. The observed band structure can be explained by considering a Jortner−type model, where pseudoatoms are placed in these holes. The electride Li(NH3)...
Iron has a bcc unit cell with a cell dimension of 286.65 pm. The density of Fe is 7.874 g/cc. Use this information to calculate Avogadro's number. Calculate the number of atoms per cubic meter in aluminum. Diamond crystals have a= 0.35670 nm and z = 8. ...
a cubic primitive packing of 32 Ga atoms with Ta, Cu, and Ga in cubic voids and 13 vacancies. The pentagonal-prismatic coordination of Ta and Cu can formally be obtained from the cubic primitive packing of Ga atoms by a 45° rotation of a part of the Ga8 cubes. There is a close ...

The DFT calculation was based on a large unit cell model of 100-atom supercell, with randomly distributed five element atoms. The mechanical properties of all three RHEAs were calculated and compared. Comparing with the other two RHEAs, Mo15Nb20Re15Ta30W20possesses balanced mechanical properties ...
