Neodymium is one of the more reactive lanthanides—a group of similar metallic elements numbered 57-71 on the periodic table. These 15 elements, plus scandium and yttrium, are termed "rare earth elements" (REEs). Rare earths have important uses in a number of key applications for multiple advanced technologies in electronics, transportation, energy and defense.

Read MoreTHE CHEMISTRY OF MINE DRAINAGE. Because the chemistry of water samples can rapidly change if removed from the mine, many mine drainage measurements are made in the field. The first measurement typically looks at acidity, which is reported as pH. A neutral pH has a value of 7. Any sample that reads below a pH of 7 is characterized as being …
Read MoreUses and properties. Image explanation. Lead has been known to, and used by, humans for many centuries. This long history is reflected in the image by the use of an early alchemical symbol for lead and carved Ancient Roman characters. Appearance. A dull, silvery-grey metal.

Read MoreAn oft-overlooked facet of the post-HTS process is the data hand-off between HTS and medicinal chemistry. Data mining for less obvious 'hits' (e.g., less potent but more ligand-efficient compounds) is an increasingly utilized strategy [56,57]. A major obstacle to employing this and related strategies with confidence can be data quality.
