(1996)Positive Gd anomalies in shale-normalised rare earth element (REESN) patterns of natural waters may provide information on the types of ligands which control surface complexation of REE on particle surfaces. However, REESN ...
-
(1998)The solubilities of pure synthetic La and Gd hydroxides were measured in aqueous solutions over a wide range of pH (5-9.5) and temperature (40-150°C). The regression of these data is used to determine the first dissociation ...
-
(1999)Large isotopic deviations of 149Sm-150Sm and 157Gd-158Gd derived from neutron capture effects were observed in five enstatite achondrites (aubrites); Norton County, ALH78113, Cumberland Falls, Bishopville and Mayo Belwa. ...
-
(2000)Isotopic compositions of Sm and Gd in eight chondrites (Mezo-Madaras, Parnallee, Otis, Suizhou, Zhaodong, Allende, Bruderheim and Y-74191) were measured to study neutron capture effects due to the interaction of cosmic ...
-
(2001)The bombardment of the lunar surface by cosmic rays produces secondary neutrons, some of which are thermalized by the lunar soil and then interact strongly with the isotopes of Cd, Gd and Sm which have high neutron capture ...
-
(2000)The stability of aqueous complexes formed by gadolinium (Gd3+) and ytterbium (Yb3+) aqueous species with the acetate ion (AcO-) was investigated at 25°C, 40°C, 60°C and 80°C, and saturated vapor pressure, using potentiometric ...

(2006)Enstatite achondrites (aubrites) when compared to other stone meteorites have unusually long cosmic-ray exposure (CRE) ages. We report here the 150Sm/149Sm and 158Gd/157Gd ratios in six different structural phases, i.e., ...
