Autor: U. van Bürck, H. Franz, K. Messel, Robert E. Dinnebier, T. Asthalter, E. Schreier

Publikováno v: Journal of Physics and Chemistry of Solids. 64:677-684

The onset of dynamics and the structural changes of octamethyl–ethinyl-ferrocene around a solid–solid phase transition at 248 K have been investigated using the novel technique of quasielastic nuclear forward scattering (QNFS) in a temperature ra

The microscopic dynamics of dibutylphthalate/ferrocene in nanoporous silica matrices with pore sizes of 25, 50, 75, and 200 A, respectively, has been investigated in a temperature range between 70 and 200 K by nuclear resonant scattering of synchrotr

Publikováno v: Jiang, J, Saksl, K, Saida, J, Inoue, A, Franz, H, Messel, K & Lathe, C 2002, ' Evidence of polymorphous amorphous-to-quasicrystalline phase transformation in Zr66.7Pd33.3 metallic glass ', Applied Physics Letters, vol. 80, no. 5, pp. 781-783 . https://doi.org/10.1063/1.1447015

The amorphous-to-quasicrystalline phase transformation and the pressure effect on the transformation in a Zr66.7Pd33.3 metallic glass have been investigated by in situ x-ray diffraction measurements using synchrotron radiation. It is found that the t

Glass dynamics and scaling behaviour under pressure using quasielastic nuclear forward scattering

Autor: R. Verbeni, I. Sergueev, K. Messel, T. Asthalter, W. Petry, H. Franz

Publikováno v: Hyperfine Interactions (C) ISBN: 9781402010873

We have investigated the influence of pressure on the α-relaxation in dibutylphthalate/ferrocene using quasielastic nuclear forward scattering of synchrotron radiation, in a temperature range between 150 and 250 K and for pressures up to 4kbar. As e
