We have measured the phonon density of states (PDOS) of isolated bcc and fcc FexAu1-x alloy nanoclusters (NCs) by nuclear resonant inelastic x-ray scattering. Drastic deviations were observed with respect to the PDOS of bulk Fe–Au alloys. Important information on the structure and thermodynamic properties of these NCs was obtained.

    It is shown that the thermal conduction in dielectric glasses at ultralow temperatures is provided by energy transfer over the infinite cluster of resonance pairs of two-level systems. Expressions for the phononless thermal conductivity coefficient (∼ T[sup 4/3]) and for the temperature of...

    In this work, we have proposed a fitting model to evaluate thermal diffuse scattering in the case of high energy incident x ray with Laue transmission scattering, applicable in future studies on samples at high pressure in a diamond anvil cell. We show that the fitting model including a Voigt...

    We present Raman-scattering measurements on InxGa1-xN over the entire composition range of the alloy. The frequencies of the A1(LO) and E2 modes are reported and show a good agreement with the one-mode behavior dispersion predicted by the modified random-element isodisplacement model. The A1(LO)...

    Inelastic neutron scattering and nuclear resonant inelastic x-ray scattering were used to determine the phonon densities of states of face-centered-cubic Ni-Fe alloys. Increasing Fe concentration results in an average softening of the phonon modes. Chemical ordering of the Ni0.72Fe0.28 alloy...

    To be able to control the functions of engineered multicomponent nanomaterials, a detailed understanding of heterogeneous nucleation at the nanoscale is essential. Here, by using in situ synchrotron X-ray scattering, we show that in the heterogeneous nucleation and growth of Au on Pt or Pt-alloy...
