Chemical elements and element groups
Tintina gold province study, Alaska and Yukon Territory, 2002-2007 [ More info] New discoveries and modernized extraction methods prompted renewed interest in gold deposits in this part of central Alaska, prompting a variety of studies described here.
Titanium: light, strong, and white [ More info] Titanium is highly resistant to corrosion and is chemically inert. It is as strong as steel but 45 percent lighter, and it is twice as strong as aluminum but only 60 percent heavier.
Trace metals related to historical iron smelting at Hopewell Furnace National Historic Site, Berks and Chester Counties, Pennsylvania [ More info] Iron ore containing elevated concentrations of trace metals was smelted here during 113 years of operation (1771-1883). We sampled a variety of materials nearby to determine the amount of metals such as arsenic, chromium, copper, lead, and zinc.
What Mobilizes Arsenic in Ground Water? [ More info] Research findings and examples of application to real problems--chemical reactions between nitrate, iron, and oxygen can affect the mobility of trace amounts of arsenic.
Zinc-The key to preventing corrosion [ More info] Explains how we use zinc, where it comes from, and discusses worldwide supply and demand.
