Hi folks - Here is the Friday Element Quiz Answer. Sorry for the long
delay as I was out on business travel:
The Question:
This element has low ductility and high reactivity to air resulting in
limited industrial uses. The largest use of this element is in the
electronics industry in resistors and in hybrid integrated circuits. This
element is used as a catalyst in the petroleum refining industry.
Additions of this element to Titanium piping result in a significant
corrosion resistance improvement for sour gas oil well applications. What
element is being described?
The Answer:
The element is Ruthenium (Ru). Ruthenium is a member of the platinum group
metals (PGMs). PGMs are some of the least abundant elements in the Earth's
crust but have a number of unique characteristics. Ru is the least costly
of the PGMs and is used extensively by the electronics industry in
resistors, integrated circuits, Ta capacitors and computer hard disks. The
Russian scientist Karl Ernst Claus discovered Ru in 1844.
The winner of this quiz is Denny Fritz of SAIC. A number of the other PGMs
elements were suggested so many folks were on the right track in their
sleuthing. Clumpy and his cousin Kloumpios will fire up their John Deere
tractors and head for Indiana to work for Denny. I saw them putting chains
on the back tires so this weekend's late winter snow storm won't stop them
from traveling. Kloumpios seemed extremely unhappy about the snow but was
determined to not let it interfere with their travel.
So far Clumpy and Kloumpios have:
Week 1 Lamar Young, SCS Coatings
- accomplished nothing (drank lots of coffee)
Week 2 Bev Christian, RIM
- conducted REACH material testing
Week 3 Drew Meyer, Benchmark Electronics Inc.
- Solderability testing and mowed the lawn

Week 12 Steve Creswick of Balanced Enterprise Solutions
- Acted as Steve's "go fer" due to a broken leg!
Week 13 Gebhard Neifer, Delphi
- conducted a plasma pre treatment Taguchi DOE for a sealing process
Week 14 Bev Christian, RIM
- assisted with a tin pest investigation/test
Week 15 Bev Christian, RIM
