NDIIF Announces Two Awards — Best Imaging Publications for 2015

Nina Welding • DATE: May 5, 2016

The Notre Dame Integrated Imaging Facility (NDIIF) is pleased to announce two awards for the best imaging publications for calendar year 2015 - April 15, 2016.

The Best Electron Microscopy Imaging Publication 2015 was awarded to Sara Fathipour, a graduate student with Professor Alan C. Seabaugh in the Department of Electrical Engineering.
Fathipour and colleagues published a paper entitled “Synthesized Multiwall MoS2 Nanotube and Nanoribbon Field-Effect Transistors.” Using advanced transmission electron microscopy, the study revealed surprising physical attributes of MoS2 nanotubes grown by chemical vapor transport and used as the channel in field effect transistors. Instead of being cylindrical in geometry the tubes have an ellipsoidal cross section with a semimajor axis of ~60 nm, a semiminor axis of ~30 nm, and a bending radius on the   order of 2 nm. The transistors have ON/OFF current ratios more than 20 x greater than MoS2 nanotubes field effect transistors grown other methods. Their work was published in Applied Physics Letters.

The Best Biological Imaging Publication 2015 is awarded to Manuela Lahne, a research assistant professor collaborating with Professor David Hyde in the Department of Biological Sciences and the Center for Zebrafish Research.
Lahne and coworkers published a paper entitled “Actin-Cytoskeleton- and Rock-Mediated INM Are Required for Photoreceptor Regeneration in the Adult Zebrafish Retina.” The study employed regular and multiphoton confocal cell microscopy to monitor in real time the behavior  of Müller glia/neuronal progenitor cells in light damaged adult zebrafish retinal cultures. Continuous live cell imaging for several  hours through  the  retinal  thickness enabled observation of Müller glia/NPC nuclei migrating from the inner to the outer nuclear layer of the retina to divide before the majority of nuclei returned to the inner nuclear layer. The study was published in the Journal of Neuroscience.

Bradley Smith, director of the NDIIF states, “These outstanding publications illustrate the cutting-edge science and engineering research that is enabled by the superb imaging equipment within the NDIIF.”
