We welcomed two visiting graduate students to the group this month. André Navarro de Miranda comes to us from the University of Campinas (Unicamp) in San Paulo, Brazil. He'll be using SSRL's X-rays to continue his work studying electrocatalysts for rechargable Li-air batteries. Our second visiting student is Samuel Welborn who is coming to us from the University of Pennsylvania in Philly. He'll be using the X-rays to study his 3D structured cathodes with nano-tomography.
