  • The presence of guest atoms—known as rattlers—in the cages of some clathrate structures is considered to be responsible for the low thermal conductivity of the materials. Neutron spectroscopy provides important evidence regarding the actual phonon dispersion in the material, and the precise way in which this is influenced by rattlers.

  • A combined experimental and theoretical investigation of phononic properties in nanocrystal-based semiconductors reveals that unusually strong coupling between phonons and electrons originates from the mechanical softness of the surfaces of the nanocrystalline domains and sheds new light on their recombination in nanocrystal-based devices.

  • A specifically designed family of synthetic lipids exhibits unique liquid-crystalline behaviour at low temperature, enabling maintenance of amorphous water down to about 10 K due to nanoconfinement.

  • Phonon engineering enables tailored heat-transfer properties, controlled elastic and acoustic vibration propagation, and custom phonon-electron and phonon-photon interactions. Here, the authors present an approach for the observation and tunability of vibrational modes of nanocrystal superlattices.
