And it turns out PtSn4 is kind of a Goldilocks material! Neighbouring compounds and even isoelectronic and nearly identically sized Pd have lower RRR!

Intrinsic defect intolerance in the ultra-pure metal PtSn4 - Communications Materials
Ultra-pure materials are essential for exploring intrinsic physics, yet achieving such purity often demands extensive crystal growth optimization. Here, the authors reveal that PtSn4 naturally exhibit...

The answer? Well, there really are just very, very few defects! Even when trying to grow “bad” crystals. So few defects we had to think about how to characterize uncertainties when counting from different size images and areas.

Wild and utterly short-sighted! 🤯
Curiously, we are seeing rapid growth in our program. Unclear why, but at least some students are coming from Comp Sci. Physics provides a broad based, rigorous cognitive framework for quantitative thought. I think students are recognizing this amid uncertainty.

I just got an email from DOE having reviewed for them before. Hard to read and believe the depth of it.

Oh, Sarah Burke is a VERY common name so it’s actually not that easy to track me down! No worries! Thanks very much for adding me!

Thanks for helping us find each other over here!

Oh, I did this 3 weeks ago (tripped up concrete stairs) and had bloody knuckles going back into a workshop and for a government official’s tour. 🤦🏻‍♀️ Just healed now. Annoying but could have been worse as you say!
