Cd Nuclear Quadrupole Interaction in CdCl 2 and its Monohydrate
نویسندگان
چکیده
The nuclear quadrupole interaction (NQI) in layered transition metal dichalcogenides usually decreases linearly with increasing temperature [1]. This behaviour was attributed to anisotropic lattice vibrations and is the two-dimensional analog of the Tpower law in three dimensions [2], In order to investigate the origin of this linear power law further we choose another layered compound, namely the chloride of the post-transition metal Cd. Since there is no suitable isotope for NQI studies by NMR or NQR, we used the time differential perturbed angular correlation (TDPAC) of y-rays of l l l m Cd(T 1 / 2 = 48.6 min). Since CdCl2 is hygroscopic, we studied in addition in detail the NQI of its monohydrate.

متن کاملEstrogen-like effects of diet-derived cadmium differ from those of orally administered CdCl(2) in the ERE-luc estrogen reporter mouse model.
Cadmium (Cd), an environmental and dietary contaminant, has been described to mimic the effects of 17β-estradiol (E(2)) in selected model systems when studied as an inorganic salt. However, inorganic Cd salts do not represent the main form of Cd exposure in general human populations. The aims of this study were to compare the estrogen-like effects and the bioavailability of dietary Cd to inorga...
