Student SEM Image Contest 2014

Striking and beautiful microscopic images of tiny materials and objects are often developed in UCLA laboratories while conducting research.

Some of the most striking images from the current school year were recently honored in the fifth annual Best SEM (Scanning Electron Microscope) Image Contest. The contest is sponsored by the Molecular and Nano Archaeology Laboratory, a joint venture between the Materials Science and Engineering Department at the UCLA Henry Samueli School of Engineering and Applied Science and the Cotsen Institute of Archaeology at UCLA.

More than 150 researchers use the lab’s SEM Nova Nano 230 microscope, made by FEI Co.
Winners of the MNA Award were determined by associate professor Ioanna Kakoulli, Christian Fischer and Sergey Prikhodko, co-directors of the MNA Lab, and past winner Jonathan Quan. The FEI Tony Award was judged this year by FEI representative Tony Carpenter. This year MSE  student Yuan-Wei Edward Chang won first prize in both categories for an image called “Magnesium Shuffle.”
