| 31. | The Ames Laboratory retained a focus on chemistry and metallurgy, particularly of the rare earth metals.
|
| 32. | The following steps and process flow diagram detail the rare earth metal extraction process from the ore.
|
| 33. | Like other chalcogenides of the alkaline earth metals, BaS is a short wavelength emitters for electronic displays.
|
| 34. | Its ion-complexing capability allows beauvericin to transport alkaline earth metal and alkali metal ions across cell membranes.
|
| 35. | Holmium is relatively inexpensive for a rare-earth metal with the price about US $ 1000 per kg.
|
| 36. | The converters use rare earth metals, oxides such as cerium and lanthanum, that are plentiful in China.
|
| 37. | The alkaline earth metals were precipitated either as sulfates or oxalates, leaving the alkali metal in the solution.
|
| 38. | Research carried out by CNRS developed new high-energy hybrid alloys incorporating rare earth metals for the negative electrode.
|
| 39. | Sodium is referred to as a alkali metal and magnesium is referred to as a akalne earth metal.
|
| 40. | This allows these alkaline earth metals to substitute in for calcium in the aragonite without affecting the crystalline structure.
