We drove from Spokane to Calgary, and along the way skied at Red Mountain, Revelstoke, and Kicking Horse. Here is a panorama from the top of Kicking Horse, perhaps the most spectacular view I have ever seen at any ski area ever.

This is the plastic bag we keep our nativity scene in. It says “No man, no law, no war can stop him”. I like to think it is referring to Jesus. On the back is an advertisement for soccer. The nativity (and bag) were a gift from my sister from when she lived in Zambia.

This week I had a paper on nucleation phenomena in nanoparticles accepted to the journal Nano Letters. The major conclusions of the work is that nucleation of a second phase is likely to always occur at the surfaces of nanoparticles, and the barrier energy is size dependent as a result of coherency strain, and scales with a particle’s area/volume ratio. The barrier disappears below a critical size. A preprint of the paper is available here. Below is a video of a LiFePO4 nanoparticle being discharged. The lithiated phase forms at the edges of the particle and then moves inward as the particle fills.
