I thought you would suggest Titan rocket, or apollo.

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

Dave has asked me how Clumpy is going to get to Cyprus.  Dave often throws 
these logistical puzzles at me when they need to be done with style and 
flair. 

Cyprus of course, blends the very old world with the very new, as we have 
seen from Brian's Christmas videos in the past.  So, in that spirit, 
Clumpy has constructed a large raft of papyrus reeds, in the same manner 
as the epic explorer Thor Heyerdahl and his Ra II craft.  Unfortunately, 
with the present weather, tides and currents, it would take forever to get 
there.  Fortunately, Dave and I have one of our former coops (one of our 
Minions) who now works for Rolls Royce Turbine Engines.  She has sent us 
one jet engine and two Jet Assist Take Off (JATO) rockets.  Clumpy should 
be to Cyprus shortly.

[TN] NTC Friday Element Quiz - the Answer






Hi folks - Here is the Friday Element Quiz Answer:

The Question:

This element has two allotropic phases - one is an FCC structure and one
is a HCP structure. This element plays a critical role as an alloying 
element in a wide range of metal alloys, cermets and protective
coatings. This element has only one stable isotope which finds use in food 


sterilization and medical radiotherapy. Nearly 6 billion tons of this 
element are estimated to exist on the world's seafloor but are not 
economically recoverable at today's metal prices. What element is being 
described?

Bonus question: In what year was this element's oxide first reduced to 
produce the pure element?

The Answer:

The element is Cobalt (Co). Cobalt is a very important element in terms of 

an alloying constituent in steel, superalloys, and ceramics. About 40% of 
the world Cobalt production is used to produce Co compounds for 
decolorizing and colorizing glass, potter, paint, ink and as additives to 
rechargeable Li-ion batteries. Early computer disks used Fe2O3 particles 
dispersed in an epoxy phenolic resin as the magnetic recording media. 
These disks worked well for moderate data storage densities. However, 
higher storage densities require thin film rather than particles. Cobalt 
based thin film compositions such as Co-Pt-B or Co-Cr-Ta are used in those 

applications.

The winner of this week's quiz is Brian Ellis so Clumpy will be packing 
the John Deere and heading to Cyprus.  Bev Christian correctly answered 
the bonus question - the year was 1735.

Week 1 Lamar Young, SCS Coatings
