FIP Seminar Series - Dr. Kenneth M. Kemner "A multi-modal approach to image dynamical interactions with the root-microbe system"

"A multi-modal approach to image dynamical interactions with the root-microbe system" Dr. Kenneth M. Kemner, Research Scientist, Biogeochemical Processes Group, Bioscience Division, Argonne National LaboratoryTuesday, November 17, 201512:00pm | 330 Gross HallDuring this presentation, I will provide a broad overview of the Argonne Small Worlds project with a particular focus on x-ray fluorescence-based imaging that makes use of quantum dots as a contrast agent. This will include an introduction to synchrotron radiation and x-ray absorption and fluorescence processes. Finally, I will present preliminary results of x-ray absorption measurements recently made on gold nanospheres and ¿nanostars¿ in collaboration with researchers at Duke.
