I'll take the "other" one for general lab work.

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. Denny Fritz -----Original Message----- From: David D.

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. o 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 4 Ian Fox, Goodrich had an epic journey of travel Week 4 Gary Ferrari, Garrick Global unknown Week 5 Fredrick Miller, Astrolab unknown Week 6 David Nelson, Raytheon Were tackling dummys for Dallas Cowboys Week 7 Graham Collins, L3 Communications Cleaned gutters and painted window trim Week 8 Bill Noel, ITT Geospatial Systems Division unknown Week 9 Steve Gregory of RD Circuits unknown Week 10 David Bealer of Watchfire Signs descaled the in-line wash machine! Ouch! Week 11 Dick Krug of Sparton Corporation assisted with AS9100 quality management systems requirements audit 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 - assisted Bev shoveling snow Week 16 David Bealer of Watchfire Signs - assisted with reflow profiling Week 17 Brian Ellis, rumored to be retired - assisted with rewiring the house, had a tractor accident and found his ousin Kloumpios Week 18 Denny Fritz, SAIC - assisted with tin whisker inspection/examinations Week 19 Graham Collins, L3 Communications assisted with scraping barnacles, boat paint and boat engine maintenance Week 20 Mark Woolley, PTRL Laboratory Avaya assisted with weather observations (70F to snow) and resolving lectrochemical migration failures Week 20 Tom Carroll, Boeing Defense, Space and Security assisted with commercial aircraft galley inspection Week 21 Brian Ellis, supposedly retired, and Tom Carroll, Boeing Defense, pace and Security assisted with root cause corrective action tasks assisted with nothing but catching up with the family Week 22 Drew Meyer, Benchmark Electronics Inc. assisted with metallographic cross-sections and Dye & Pry testing Week 23 Bev Christian, RIM assisted with a creep corrosion project and the setting up of an oxygen omb Week 24 Steve Gregory, RD Circuits unknown Week 25 Ahne Oosterhof, A-Laser assisted with stencil aperture data analysis and split/stacked firewood Week 26 Scott Post, Delphi assisted/participated in the Kokomo Airshow Race Event Week 27 Brian Ellis, supposedly retired assisted with tedious website work and family home cooking Week 28 Nigel Burtt abandoned Nigel and were rumored to be involved in UK News Corps/News nternational cellphone/journalism/politics scandal Week 29 Richard Stadem,GD-AIS unknown Week 30 Robert Wolfe, Kimchuk Inc and Graham Naisbitt, Gen3 assisted with a hot tub refurbishment for post work day de-stressing assisted with SIR and Cleanliness testing Week 31 Bev Christian, RIM Inc, and Denny Fritz, SAIC assisted with ????
