Cornell Announces Results of Materials Images Competition The Department of Materials Science and Engineering (MSE) at Cornell University announces the results of its first Microscopy Image Competition: Images in the Material World, which it co-sponsored with the Delta Chapter of Alpha Sigma Mu. Three awards were given in two categories: Most

States and Canada. The entrants were judged by Stephen Sass, a professor in the MSE department, and Christopher Ober, director and professor in the department. The next competition is planned for this fall; details will be posted on the MSE Web site at www.mse.cornell.edu.
Scientifically Significant Image and Most Artistic Image. Prizes of digital cameras have been made available through the generosity of the Eastman Kodak Company. The competition was the first in what is expected to be an annual event promoted to undergraduate students in the United

Pentacene Growth at Elevated Temperature
Platinum Palm Tree
Christopher Johnson, Cornell University Imaging: Atomic Force Microscope Description: A segment of a remarkably large grain of pentacene grown on a silicon substrate at elevated temperature with inset of pentacene growth at room temperature.
Megan Cordill, Washington State University Imaging: Optical Microscope Description: Straight buckles spontaneously formed in a palm tree shape after sputter deposition of a platinum film on SiO2.

Structural Surface View of a Sintered Carbide Sample Nagesh Rao Rensselaer Polytechnic Institute Imaging: Scanning Electron Microscope Description: A sintered carbide sample’s surface structure at 5000× magnification using a working distance of 27 mm. Crystal structures of 1-µm-size can be seen in the collage of the grain boundaries.
Platinum Worm Megan Cordill Washington State University Imaging: Atomic Force Microscope Description: A thin film of SiO2 spontaneously delaminated forming telephone cord buckles.
Microstructure of a 319-Aluminum Alloy Jonathan Liddy University of Connecticut Imaging: Optical Microscope, negative photo image Description: Microstructure of a 319aluminum alloy (7.47Si-3.84Cu-0.47Fe0.24Mg-0.613Zn-0.29Mn-0.14Ti), heat treated at 505°C for 6 h, quenched, and aged at 230°C for 3.5 h. Black is the alpha phase (matrix); yellow is the Si phase (Al2 Cu); and impurities are colored red, green, and purple.
Hot! Joel LeBret Washington State University Imaging: Transmission Electron Microscope Description: A crack and interference fringes combined to produce this effect in this specimen of vanadate.
