Eleven Rare Earth Companies to watch, including Molycorp ...

Rare earths were discovered by chance at Mountain Pass when uranium prospectors sent samples to the USGS for analysis in 1948. The Molybdenum Corporation of America, (later renamed Molycorp), acquired the mining rights, production began in 1952, an expanded concentrator was built in the 1960s and a new separation plant in the 1980s.

Anionic Cerium Oxide Nanoparticles Protect Plant ...

Plant abiotic stress leads to accumulation of reactive oxygen species (ROS) and a consequent decrease in photosynthetic performance. We demonstrate that a plant nanobionics approach of localizing negatively charged, sub-11 nm, spherical cerium oxide nanoparticles (nanoceria) inside chloroplasts in vivo augments ROS scavenging and photosynthesis of Arabidopsis thaliana plants under excess light ...

The effects of cerium and lanthanum on the vegetative growth, floral initiation and reproductive growth of Arabidopsis thaliana were studied. Addition of cerium nitrate (0.510 μM) or lanthanum nitrate (0.550 μM) to the culture medium significantly increased the lengths of primary roots, but had no significant effects on the number of rosette leaves produced per plant, plant heights and ...
