This week is a bit strange for me. First of all (as I've mentioned before) there are no kids at home. Second, we just got back from a whirl wind trip to Utah and I will be leaving again in three days. I don't really have enough vacation days for all these trips so I'm trying to put in some extra hours to ease the burden. As it turns out, that is great because my project is going very well and I'm anxious to work on it. I am more than willing to work twelve hour days because I'm making great progress and loving every minute of it. I thought that I'd share one of my failures with you. When I test my thermoelectric materials they have to be tested in an inert atmosphere. Any leaks and the oxygen will quickly destroy the materials good properties. While that is very ugly, our heaters are made of Molybdenum and when Mo oxidizes it forms very beautiful crystals. After my last encounter with a leaking test station I decided to take a picture of the MoO3 crystals to share with you. They really are quite pretty aren't they?
