We explore the formation of R2Fe14X (R = Ce, Nd; X = B, C, Al, Si, P, S, Ga, Ge, Zr, Sn) and R2Co14B (R = Ce, Nd) phases having the Nd2Fe14B structure type by means of density functional theory. Only R2Fe14X (R = Ce, Nd; X = B, C) and Nd2Co14B are kn

We explore the formation of a LaFe5Hn hydride by means of density functional theory. Enthalpies of formation ΔH with respect to the elemental metals and H2 are calculated for various hydrogen configurations in four prototype crystal structures. We f

Systematic theoretical results for La(TM) 5 H n materials with TM one of the magnetic transition metals Fe, Co, or Ni are discussed. For TM = Co, Ni the antecedent LaCo 5 and LaNi 5 intermetallics and hydrides are well known. While no La–Fe compoun

Mathematical simulation has been used in mineral processing system design, optimization and control for more than 30 years. In recent years, a new set of simulation tools based on the physics of the underlying processes was developed. Because these m

An approximate semi-empirical model is developed for estimating the enthalpy of formation and hydrogen content of quaternary AB n C m H x hydrides. Results are in favorable agreement with experiment for a variety of materials, including complex hydri

While originally formulated to predict the enthalpy of formation, Miedema’s model for metal hydrides is also capable of predicting hydrogen content. In the case of binary AH x hydrides this is straightforward. For ternary AB n H x hydrides extensio

We have prepared Li-doped multiwall carbon nanotubes and Li- and K-intercalated graphite and measured their hydrogen storage properties using a thermogravimetric analyzer (TGA). In a flowing H2 atmosphere Li-doped nanotubes and Li-intercalated graphi
