Strength of the repulsive part of the interatomic potential determines fragility in metallic liquids   pp792 - 796
Christopher E. Pueblo, Minhua Sun and K. F. Kelton
doi:10.1038/nmat4935
Liquid fragility is a basic characteristic of glasses and there is debate as to what controls it. X-ray scattering of several metallic liquids now suggests that the strength of the repulsive part of the interatomic potential is key.

T. Ideue, T. Kurumaji, S. Ishiwata and Y. Tokura
doi:10.1038/nmat4905
Giant coupling between magnetism and phonons — or the giant thermal Hall effect — is reported in the insulating polar magnet (ZnxFe1-x)2Mo3O8.

Synthesis of Ti3AuC2, Ti3Au2C2 and Ti3IrC2 by noble metal substitution reaction in Ti3SiC2 for high-temperature-stable Ohmic contacts to SiC   pp814 - 818
Hossein Fashandi, Martin Dahlqvist, Jun Lu, Justinas Palisaitis, Sergei I. Simak et al.
doi:10.1038/nmat4896
Substitution of Si with Au and Ir in Ti3SiC2 through a solid-state diffusion process allows the synthesis of Ti3AuC2, Ti3Au2C2 and Ti3IrC2 phases able to form Ohmic contacts with SiC stable at high temperatures under ambient air conditions.

Excitation-wavelength-dependent small polaron trapping of photoexcited carriers in α-Fe2O3   pp819 - 825

doi:10.1038/nmat4919
Aqueous rechargeable batteries are promising for grid storage and electric vehicles, but they suffer from poor cycle life due to anode instability. Exploiting stable ion-coordination charge storage and chemical inertness towards aqueous electrolytes, quinones are now reported as stable anodes.
