Charge Redistribution and Phonon Entropy of Vanadium Alloys [PDF]
The effects of alloying on the lattice dynamics of vanadium were investigated using inelastic neutron scattering. Phonon densities of states were obtained for bcc solid solutions of V with 3d, 4d, and 5d transition metal solutes, from which vibrational ...

Predicting the Volumes of Crystals [PDF]
New crystal structures are frequently derived by performing ionic substitutions on known crystal structures. These derived structures are then used in further experimental analysis, or as the initial guess for structural optimization in electronic ...

Bondonic Effects in Group-IV Honeycomb Nanoribbons with Stone-Wales Topological Defects
This work advances the modeling of bondonic effects on graphenic and honeycomb structures, with an original two-fold generalization: (i) by employing the fourth order path integral bondonic formalism in considering the high order derivatives of the ...
