  1. Industry Collaboration: New Magnetic Wobble StickPaul M. Thibado, University of Arkansas, DMR 0855358 Imagine interfacing a French-made semiconductor growth chamber with a German-made semiconductor characterization facility which are both under vacuum. Wobble sticks provide the missing link, allowing a sample to be gingerly moved from one custom style mount to the other. To-date, these devices are expensive and offer sample grasping, sample translation, and a small amount of angular flex (cone-angle wobble). We teamed with industry to design (now they sell) a new magnetic wobble stick, which does all the regular things, but it is also 5 times less expensive and provides 360º axial rotation. Squeezing the handle paddles pushes two magnets together causing a central wire to push open the pincer. Releasing allows an inter-magnet spring to expand and close the pincer. Sliding, twisting, or tilting the handle causes the inner tube holding the sample to translate, rotate, or wobble, respectively. Handle With Magnets Pincer wire tube Handle w/Magnets Pincer

  2. High School Physics Day Paul M. Thibado, University of Arkansas, DMR 0855358 High school students from all over Arkansas visit our department on a Friday. Typically, about 5 buses full of high school students come for the day. Top photo, Steven Barber (research group member to the far upper left) is giving a tour of our semiconductor growth chamber and our scanning tunneling microscope facility. Lower left photo, Matt Ackerman (research group member to the far right) is directing the next tour where to go next. Lower right photo, a close up of two visitors.
