The diffusion characteristics of Mg–rare-earth diffusion couples were studied. Cylinders of pure Mg and rare earth (Dy, Nd, and Pr) were abutted and annealed at 500 °C for 100 h or 300 h. Point-by-point composition profiles were collected starting in pure Mg, across the diffusion zone, and ending in the pure rare earth, using energy dispersive x-ray spectroscopy with a scanning electron microsc...

The impact of phase morphology in electrically conducting polymer composites has become essential for the efficiency of the various functional applications, in which the continuity of the electroactive paths in multicomponent systems is essential. For instance in bulk heterojunction organic solar cells, where the light-induced electron transfer through photon absorption creating excitons (elect...

Two-step process: Li0.33La0.57TiO3 / LiCoO2 (LLTO/LCO) half-cells were prepared by a two-step joining process and an electron microscopic analysis was performed in the interfacial region. The authors identified three additional regions formed interdiffusion between Ti Mn. resistance of layer 105 ? is considered to be main origin LLTO/LCO half-cell.

Modelling the mixing process of multicomponent liquids is still an open problem. In this work the possibility to use nuclear magnetic resonance (NMR) to measure concentration profiles during interdiffusion of a binary system is discussed. NMR is a non-invasive technique that can be used to measure diffusivities of liquids over the complete viscosity range even for optically non-transparent samp...

In a comment on our recent letter, Yu first pointed out that there was strong alloying between the Ge dots and Si barrier layers because of the appearance of Si–Ge modes as also observed in SiGe alloys. It is correct that the Ge dot samples reported in our letter have some degrees of alloying due to interdiffusion. This was due to the fact that the samples were grown at a high temperature of 60...
