Here is the Element Quiz Question:

The Question:
This element is named after the mineral it is sourced. It has a number of
commercial applications including magnets, chemical catalysts and cancer
treatment. Prior to the 1950s, it had no application in it pure form but it
was found in "Lindsey Mix" compound used in early nuclear reactors. Which
element is being described?

The Answer:
The element is Samarium (Sm)! Samarium is a critical component of
samarium–cobalt magnets, which have a nominal composition of SmCo5 or
Sm2Co17. They have high permanent magnetization, which is about 10,000
times that of iron and is second only to that of neodymium magnets. These
magnets are found in small motors, headphones, and high-end magnetic
pickups for guitars. Samarium is used as a chemical catalyst for the
 dechlorination of pollutants such as polychlorinated biphenyls (PCBs), as
well as the dehydration and dehydrogenation of ethanol. Radioactive
samarium-153 is a beta emitter with a half-life of 46.3 hours. It is used
to kill cancer cells in the treatment of lung cancer, prostate cancer,
breast cancer, and osteosarcoma. A mixture of samarium and gadolinium (aka
Lindsay Mix) was thought to have been used for nuclear control rods in some
early nuclear reactors. Samarium is extracted from the mineral samarskite.


The winner of the quiz is Richard Stadem and  he will get the services
of Clumpy
and Kloumpios for the week.


There won't be a quiz next week as Doug is busy with his daughter's wedding
and a fair number of the TechNet herd will be attending the SMTAI
Conference in Chicago. Clumpy and Kloumpios have gotten quite efficient at
helping with IPC specification committee action items. The Quiz will resume
the week of Sept. 25.


So far Clumpy and Kloumpios have done the following:

- You can have the boys fly into Philadelphia.  They can help load the
Calibration Certificates into our system and update the Cal date.  After
that maybe they can help audit work instructions.

Week 35 Frank Kimmey, VeriFone Inc
- assisted with ????
