The original examples of lanthanide tetrad effect in solvent extraction: A new interpretation compatible with recent progress in REE geochemistry.

GEOCHEMICAL JOURNAL, 2001
Geochmeical studies reporting lanthanide tetrad effects in natural samples often cite the original examples of tetrad effect depicted by log Kd(org/aq) for Ln(III) in the two solvent-extraction systems (Peppard et al., 1969) and its theoretical interpretation (Jorgensen, 1970; Nugent, 1970).

Cost-Effective Cementitious Material Compatible with Yucca Mountain Repository Geochemistry [PDF]

, 2004
The current plans for the Yucca Mountain (YM) repository project (YMP) use steel structures to stabilize the disposal drifts and connecting tunnels that are collectively over 100 kilometers in length. The potential exist to reduce the underground construction cost by 100s of millions of dollars and improve the repository's performance.
