TDPAC research in the border region of physics,chemistry, biology: Charge density waves,intercalation reactions,and metal proteins

Three examples for modern applications of time -differential perturbed angular correlation (TDPAC) to research in the border region of physics, chemistry, and biology are given: (i) charge density waves in layered transition-metal dichalcogenides; (ii) intercalation of Li, Ag, and In into 2H-TaS₂ monitored in situ from both the guest and the host point of view; (iii) heavy metal derivatives of small blue Cu-proteins and multi-Cu enzymes. These studies require advanced spectrometers and suitable facilities for isotope production.
