Have plenty of tin whisker inspection work for Clumpy and Kloumpios to do at our 
Merrillville, IN lab.  Who do you think will be better  - Clumpy or Kloumpios?  
We have an optical scope and the tabletop SEM - optical takes the better coordination, 
and the SEM just takes patience to pump down and to vent.  Can we take apart the 
John Deere electronics and look at those boards?  Do you know if the John Deere is 
post-2006 and RoHS compliant?

Subject: [TN] NTC Friday Element Quiz - the Answer (very late)


Hi folks - Here is the Friday Element Quiz Answer. Sorry for the long 
elay as I was out on business travel:
The Question:
This element has low ductility and high reactivity to air resulting in 
imited industrial uses. The largest use of this element is in the 
lectronics industry in resistors and in hybrid integrated circuits. This 
lement is used as a catalyst in the petroleum refining industry. 
dditions of this element to Titanium piping result in a significant 
orrosion resistance improvement for sour gas oil well applications. What 
lement is being described?
The Answer:
The element is Ruthenium (Ru). Ruthenium is a member of the platinum group 
etals (PGMs). PGMs are some of the least abundant elements in the Earth's 
rust but have a number of unique characteristics. Ru is the least costly 
f the PGMs and is used extensively by the electronics industry in 
esistors, integrated circuits, Ta capacitors and computer hard disks. The 
ussian scientist Karl Ernst Claus discovered Ru in 1844.

he winner of this quiz is Denny Fritz of SAIC. A number of the other PGMs 
lements were suggested so many folks were on the right track in their 
leuthing. Clumpy and his cousin Kloumpios will fire up their John Deere 
ractors and head for Indiana to work for Denny. I saw them putting chains 
n the back tires so this weekend's late winter snow storm won't stop them 
rom traveling. Kloumpios seemed extremely unhappy about the snow but was 
etermined to not let it interfere with their travel.
So far Clumpy and Kloumpios have:
