Cornell Announces Results of 2004 Materials Images Competition The Materials Research Society’s Student Chapter at Cornell University, in collaboration with Cornell’s Department of Materials Science and Engineering (MSE), announced the results of its third 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 professor Christopher Ober. More information on the contest is available at Web site www.mse.cornell.edu.
Most Scientifically Significant Image
Most Artistic Image
1st Place
1st Place
1 µm
Carbon Nanotube Lithography
Lead Snowflakes
Craig S. Terry, University of Washington, Seattle Imaging: Scanning electron microscope Description: The top half of the image is an imprint in 100-nm-thick poly(methyl methacrylate) of a multiwalled carbon nanotube on a Si substrate, briefly reactive-ion-etched, and coated with Teflon; the bottom half is the stamp that made the imprint. Note that the nanotube has separated from its base during mold release.
Dale Anderson, Michigan Technological University Imaging: Single-beam atomic force microscope Description: The “snowflakes” are the result of lead condensing around impurities on a single-crystal silicon substrate. The growth mechanism is believed to be vapor condensation, and the image is presented in falsecolor height mode. The width of the image is 60 µm.
2nd Place
3rd Place
Crater Christina Pina University of Texas at El Paso Imaging: Optical microscope Description: Projectile impact on a piece of stainless steel at 3.4 km/s. The crater was then cut in half, polished, and electronically etched.
The Nanotube Mother Priscilla A. Guerrero University of Texas at El Paso Imaging: Transmission electron microscope Description: Aggregate of carbon nanotubes collected from an El Paso power plant.
532
2nd Place
Tarantalum Kate Jackson Cornell University Imaging: Scanning transmission electron microscope Description: Tantalum thin film on a silicon substrate.
3rd Place
316 Daniel E. Bujanda, University of Texas at El Paso Imaging: Transmission electron microscope Description: A sample of 316L stainless steel used in forming a Caribbean steel drum.
