The structure of non-crystalline materials is one of long-standing issues to be solved in the areas of solid state physics, materials sciences and physical chemistry. In particular, element-specific techniques and new data analysis methods have recently been introduced for the determination of the ...
Fourier inversion of EXAFS data is a powerful new technique for structural investigation of non-crystalline materials with the unique capability to determine the near neighbor environment of each type of atom in a complex material. The radial structure function so obtained contains information on the ...
Non-crystalline structures are demonstrated to function as promising precursors for controlling the nano-scale structure of materials: by controlling the local structure around a minority atom added to an amorphous alloy, nanocrystalline grains are optimized for a soft magnet alloy. An organic polymer,...
Non-crystalline thin films of nickel and cobalt have been prepared by vapour deposition onto liquid-nitrogen-cooled substrates, whilst a cobalt–phosphorus alloy has been produced by electroless deposition. An electron diffraction study of these samples has been undertaken. The intensity profiles are fo...

The morphology transition from the icosahedron at the magic size of N = 55 atoms to the Marks truncated decahedron at N = 75 is analyzed in details, in order to single out kinetic trapping and entropic effects. At very low T, the cluster is kinetically trapped in an icosahedral structure....
a well-defined structure feature which dominates the mechanical properties of the disordered materials is still missing. Here, we report that nanoscale spatial heterogeneity is the inherent structural feature of metallic glasses. It has an intrinsic correlation with the strength and deformation behavior....
