Thanks Dave.  I will take whichever helper is more "scientific".   We are still counting tin whiskers - with the added charter to try to estimate the volume of tin errupting from the surface so that stress relief can be estimated.  Carol Handwerker at Purdue Lafayette is trying to correlate that back to the stress her grad students saw in the tin through instrumental means.  My summer interns start packing up for Fall Term at the end of the week, so timing couldn't be better.  Thanks for the help.

Subject: [TN] NTC Friday Element Quiz - the Answer


Hi folks - Here is the Friday Element Quiz Answer:
The Question:
This element can be machined without sparking but as a pure metal is 
ompletely useless as it corrodes rapidly. No pure samples of this element 
were produced until 1950 as it required ion-exchange chromatography 
echnique. This element is used in the production of the industry's best 
ermanent magnets. What element is being described?
Bonus question: Who developed the ion-exchange chromatography technique as 
it applies to this element and what is the name of the University where 
he development happened? (both names are necessary for credit)
The Answer:
The element is Dysprosium (Dy)! Dysprosium is one of the rare earth 
lements that is key in the production of the best kinds of permanent 
agnets - Dy and Holmium have the highest magnetic strengths of any 
lements. Dy is combined with neodymium in many magnet alloys. Dy is also 
ound in some ceramics such as barium titanium oxide for capacitors with 
igh capacitance. Frank Spedding at Iowa State University developed ion 
xchange chromatography to produce pure Dy in 1950. The ion exchange 
echnique was then applied to other rare earth element production (such as 
amarium which Denny Fritz and Curt McNamara suggested as the quiz 
nswer). I completed my undergrad and grad studies at Iowa State 
niversity and many of my professors worked with Dr. Spedding - so this 
uiz had a personal twist!

ow, that was one of the more difficult quizzes. The services of Clumpy 
nd Kloumpios will be split between assisting Denny Fritz, SAIC and Bev 
hristian, RIM Inc., for this week.
