Hydrogen embrittlement in metals (HE) is a serious challenge for the use of high strength
materials in engineering practice and a major barrier to the use of hydrogen for global …

Hydrogen will be a crucial pillar in the clean-energy foundation, and therefore, the
development of safe and cost-effective storage and transportation methods is essential to its …

Enlarged and fully updated, this new edition takes into account the considerable
experimental and theoretical progress recently made in the field. Introduction to the Physics …

There is little doubt that densities for the Earth's outer core, inferred from seismology, require
that it is constituted of an alloy of liquid iron and light elements. However, the nature of the …

High pressure promotes the formation of polyhydrides with unusually high hydrogen-to-
metal ratios. These polyhydrides have complex hydrogenic sublattices. We synthesized iron …

▪ Abstract The mechanisms of exchange of hydrogen between the deep interior and surface
of Earth, as well as the means of retention and possible abundance of hydrogen deep within …

Core segregation and atmosphere formation are two of the major processes that redistribute
the volatile elements—hydrogen (H), carbon (C), nitrogen (N), and sulfur (S)—in and around …

Because of dissolution of lighter elements such as sulfur, carbon, hydrogen, and oxygen,
Earth's outer core is about 10 percent less dense than molten iron at the relevant pressure …

A density-functional theory based empirical potential was used to explore the energies of
different types of Fe grain boundaries and free surfaces in thermodynamic equilibrium with a …

The Fe-H system has been investigated by combined x-ray diffraction studies and total
energy calculations at pressures up to 136 GPa. The experiments involve laser annealing of …
