To determine if high-dose gadolinium chelates are less nephrotoxic than iodinated contrast. Records of 342 patients who had received high-dose gadolinium (.2 to .4 mmol/kg) for magnetic resonance imaging were reviewed to identify patients who had also received iodinated contrast for radiographic examinations. Their cl…

Sequential addition of anionic and cationic polyelectrolytes may lead to the formation of multilayers at a solid surface. The buildup of such multilayers is characterized by a stepwise increase of the adsorbed amount and layer thickness and by alternating highly positive and highly negative values for the ζ-potential.…

Alternating current (ac) magnetic susceptibility data are presented for six distorted cubane complexes of the composition [Mn IV Mn III 3 O 3 X]. Each of these complexes has a well isolated S = 9 / 2 ground state. There is zero-field splitting (ZFS) in the ground states where D, the axial ZFS parameter, is found to be…
