Due to the complexity of systems in living matter nuclear techniques are not commonly used in biology and biochemistry. By approaching from simple inorganic complexes we aim to elucidate the fundamental chemistry of heavy metal ion integrations with proteins. This furthermore involves studies on de novo designed peptides, naturally occurring proteins, plants and recently also bacteria.

We report the results of photoluminescence studies of zinc oxide implanted with radioactive 117Ag which decays through Cd and In on to stable Sn. Our results show that two of the so-called I-lines, I9 and I2, both decay away in accordance with the decay of radioactive 117In. This confirms an earlier result that I9 is due to excitons bound to In donors and shows conclusively for the first time...

We have studied the lattice location of the transition metals 61Co (1.6 h) and 65Ni (2.5 h) in Si single crystals of various doping types by means of on-line Emission Channeling using Short-Lived Isotopes (IS453 EC-SLI). 65Ni was directly obtained by means of Ni RILIS ionization, while for the 61Co experiments we implanted the short-lived precursor isotope 61Mn(4.6 s) which decays via 61Fe (6...

The hyperfine interaction between the quadrupole moment of atomic nuclei and the electric field gradient (EFG) at the corresponding site provides information related to the near electronic charge distribution. Nuclear techniques such as Perturbed Angular Correlation (PAC) have been used to measure EFGs under temperature or electric field variations, for example, relating them to ferroelectric...
