    Notizen: Abstract Standard porcelain samples burnt at different temperatures were doped with LiCl, organo-Li solutions, or with fullerene solution and then dried. The depth profiles of both Li and fullerene were determined. The distributions of the incorporated dopants strongly depend on the samples' porosity. Additional ultrasonic treatment during the diffusion process has a fatal influence on the porcelain structure, resulting in enhanced dopant uptake of the remaining sample. The surface-near shape of the depth profiles is interpreted by solvation, i.e., by precipitation of the dissolved salts or fullerenes in the surface-near zone during the drying process. It is shown that the solvation effect is important only in the case of media with high porosity.

    Notizen: Abstract Li salts of acrylic acid were grafted to polyethylene, PE. It is known that li is mobile in this material at room temperature, and hence can act as a probe for newly introduced defects. After irradiation of PE(Li) with 100 keV He+ ions at different fluences the Li depth distributions were measured by NDP. Changes in the Li distributions are observed which are ascribed to bonding at oxygen, the latter one preferentially penetrating into the PE via the irradiation-damaged sample surface. With increasing sample age, i.e. after exposure to ambient atmosphere for more than half a year, Li appears to lose its original mobility.
