Staff Scientist | Electron Microscopy

Expertise

Huolin Xin is a scientific staff member in the Center for Functional Nanomaterials at Brookhaven National Laboratory. His primary field of expertise lies in developing novel 3-D, atomic-resolution, and in situ spectroscopic and imaging tools to probe the structural, chemical, and bonding changes of energy materials during chemical reactions or under external stimuli. His research at Cornell and Lawrence Berkeley National Lab spans the areas from tomographic and atomic-resolution chemical imaging of fuel cell nanoparticles to in situ environmental study of heterogeneous catalysts, all maintaining a strong focus on nanocharacterization of energy materials. In 2008, 2010, 2011, and 2012, he received Distinguished Scholar Award, Castaing Award, and Presidential Scholar Award from professional EM societies. His research has resulted in more than 30 peer-reviewed publications and 1 pending patent, six of which have been reported and highlighted by national media agencies.
