Engineering Art Contest Winner: Let It Snow Crystalline Dendrites
Image of snowflake-like crystalline dendrite wins first annual Jacobs School of Engineering Art Contest
It’s extremely rare to spot a snowflake in sunny San Diego. But nanoengineering Ph.D. student Kevin Kaufmann routinely sees snowflakes through the lens of a microscope at UC San Diego—well, crystalline dendrites that resemble picturesque snowflakes.
The image of a crystalline dendrite seen here is the winning entry of the first annual Jacobs School of Engineering Art Contest. The contest provided engineers at UC San Diego an opportunity to share their research through original artwork. Submissions included photography, microscopy images, computer graphics illustrations, journal cover art, and other media. Kaufmann received a $100 Visa gift card for his winning entry, which is featured on the Jacobs School website and social media.
Kaufmann works in the lab of nanoengineering professor Kenneth Vecchio, where he makes and studies metal alloys made of crystalline dendrites. Kaufmann captured the image of one of these crystalline dendrites using a method called transmission-mode Scanning Electron Microscopy (tSEM). This method produces images of a sample by bombarding the surface of the sample with a beam of electrons. The interactions between the electron beam and the sample then produce signals that relay information about the composition and surface features of the sample.
