Hydrogen in magnesium: new perspectives toward functional stores

TL;DR: In this paper, a new approach of tailoring the properties of metal hydrides through size restriction at the nanoscale is discussed, which already shows great promise in leading to further breakthroughs because both thermodynamics and kinetics can be effectively controlled at molecular levels.

Hydrogenation properties of Mg–Al alloys

TL;DR: In this paper, the properties of Mg-Al alloys in relation to hydrogen storage are reviewed and it is observed that the enthalpy of hydride formation of magnesium is lowered upon alloying with Al due to a slightly endothermic disproportionation reaction.

Efficiency of ab-initio total energy calculations for metals and semiconductors using a plane-wave basis set

TL;DR: A detailed description and comparison of algorithms for performing ab-initio quantum-mechanical calculations using pseudopotentials and a plane-wave basis set is presented in this article. But this is not a comparison of our algorithm with the one presented in this paper.

Soft self-consistent pseudopotentials in a generalized eigenvalue formalism.

TL;DR: Novel features are that the pseudopotential itself becomes charge-state dependent, the usual norm-conservation constraint does not apply, and a generalized eigenproblem is introduced.

Improved adsorption energetics within density-functional theory using revised Perdew-Burke-Ernzerhof functionals

TL;DR: In this paper, a simple formulation of a generalized gradient approximation for the exchange and correlation energy of electrons has been proposed by Perdew, Burke, and Ernzerhof (PBE), which improves the chemisorption energy of atoms and molecules on transition-metal surfaces.
