While solid-state diffusion is in general a slow process, exceptions are found in certain kinds of inorganic materials, predominantly concerning small cations moving in an environment of large and chemically soft anions. [...] We have used a potentiometric method, recording the change in potential after a perturbing current pulse and have studied three sulphides under the [radioactive waste] repositary conditions, namely chalcocite, chalcopyrite and bornite
The pseudo-binary system TlCo2Se2 - TlCu2Se2 has been studied in some detail, with the focus on the cobalt-rich end. [...]
We have done susceptibility measurements as well as neutron diffraction to analyse the magnetic interactions. [...] TEM discloses that, at least near 50% copper, there are strong modulations to the ordered crystallographic 3-D description.
In this abstract new results concerning the introduction of a biological sample into a mu TAS, the avoidance of unspecific absorbance in the mu TAS and the interfacing to off-chip detection (e.g. Mass spectrometry, MS) for verification are presented.
