  "textContent": "Scientists from Tokyo Metropolitan University have discovered that a hydrogen-absorbing material shrinks in one direction upon heating, so-called negative thermal expansion (NTE). They found that this NTE is driven by a phase transition in the alignment of magnetic moments, an entirely different mechanism from its hydrogen-free counterpart. The research is published in the Journal of the American Chemical Society.",
