A table is a pretty elemental object, but it can have a world of uses: A setting for a quiet family dinner, a second desk, ironing board or gaming table. Sometimes all of the above!
What’s true for a table is also true for the periodic table: Something fairly small and truly elemental filled with the stuff that makes up not just our world, but serves as the basic building blocks of the universe. The periodic table is the focus of David Pogue’s newest NOVA special, Hunting the Elements, which premieres on PBS this Wednesday night at 9 p.m. EST (check your local listings).
In a sense, David Pogue (who readers will remember from the Making Stuff series) is hunting a table, which as a rule, is a relatively easy stalk. (Tables rarely move quickly, unless they’re accidentally escaping out of the back of a speeding moving truck.) Yet the special is well worth watching, since the track of the elements takes Mr. Pogue to some pretty astonishing places, including the Ames Laboratory, the center of the Energy Department’s rare-earth efforts.
Rare-earth elements tend to be found near the bottom of the periodic table, the unpronounceable–ium’s such as dysprosium, neodymium, terbium, europium and yttrium. But they’re ascendant in importance in clean energy technologies like electric cars and the powerful permanent magnets used in efficient electric motors, as well as modern essentials ranging from lasers to laptops.
That’s what makes the work at the Ames Laboratory so important. And that’s why Mr. Pogue took a trip to the laboratory, where he talked to physicist Paul Canfield about growing single-crystal rare-earth samples, Larry Jones, the director of the Lab’s Materials Preparation Center and “Mr. Rare Earth” himself, Karl Gschneidner. Mr. Pogue also spoke with John Burba, the Chief Technology Officer at Molycorp Inc., the Western hemisphere’s only producer of rare-earth oxides, which signed a cooperative research and development agreement, or CRADA, with the Ames Laboratory last year.
“I’m hoping people who don’t know a lot about the Energy Department’s national laboratories will watch Hunting the Elements, and learn about the important research going on at the labs, and in particular, the rare-earth research at Ames Laboratory,” said Mr. Jones. He added, “Hopefully they’ll learn a little more about why DOE research is important to them.”
They will. They’ll also learn more about the amazing elements set on the periodic table as a whole, from the six essentials that make up most living things (yes, six) to the highly desirables like copper and gold. And yes, Pogue being Pogue, there will be a couple of pretty impressive explosions along the way.
