Cornell Announces Results of 2003 Materials Images Competition Cornell University’s Student Chapter of the Materials Research Society, in collaboration with the Department of Materials Science and Engineering (MS&E), announced the results of its second annual Microscopy Image Competition: Images in the Material World. Three awards
were given in each of two categories: Most Scientifically Significant Image and Most Artistic Image. Prizes of digital cameras were provided by the Eastman Kodak Company. The competition was promoted to undergraduate students in the United
States and Canada. Entries were judged by Cornell MS&E professors Stephen Sass and Christopher Ober, who is also director of the department. More information on the contest is available at Web site www.mse.cornell.edu/imagescontest.
Most Scientifically Significant Image
Most Artistic Image
1st Place
1st Place
10 µm WD28 Tin Whisker
Lone SiC-Coated Carbon Fiber
Joel LeBret, Washington State University Imaging: Scanning Electron Microscope Description: This SEM image of a tin whisker indicates the origin of striations or grooves on the surfaces of these long-time electronics hazards (i.e., when the tin whisker grows out at the surface, it acts like a wire creating a short-circuit in the electronics). The porous surface of the underlying tin grains directly produces the channels, which continue the entire length of the whisker.
Tatiana Russell, Rensselaer Polytechnic Institute Imaging: Scanning Electron Microscope Description: SEM image of a single SiC-coated carbon fiber on carbon mounting tape.
2nd Place
3rd Place
Higher-Order Dendritic Growth Erhan Altinoglu Northwestern University Imaging: Optical Microscope Description: Reconstruction of aluminum dendrites based on 110 serial sections taken at 4.75 µm intervals in an aluminum copper eutectic liquid.
Etched Precious-Metal Alloy Timothy Troutman California Polytechnic State University, San Luis Obispo Imaging: Scanning Electron Microscope Description: Etched preciousmetal-alloy electrode designed to exhibit low polarization in stimulation and sensing (patent pending).
MRS BULLETIN/AUGUST 2003
2nd Place
Asteroids Amber Schneeweis Iowa State University Imaging: Scanning Electron Microscope Description: Atomized particles of Al-15wt%Si deeply etched in nitric/phosphoric acid to reveal the unique microstructures that form during rapid solidification.
3rd Place
Circles & Squares Javier Gutierrez University of Florida Imaging: Polarized Light Microscope Description: Shape-retention of calcite crystals in CaCO3 film formation.
