BLUE SUNFLOWER Nature’s beauty isn’t limited to what can be seen in everyday life. Researchers using clean room facilities at Georgia Tech’s Institute for Electronics and Nanotechnology (IEN) are often impressed by what they see at the nanometer and micrometer scales. IEN senior research engineer Devin Brown provided the image of this structure , which was produced by accident while he was studying the pattern order exposure effects on silicon from the electronic resist material hydrogen silsesquioxane. “I find it interesting that these ‘mistakes’ in fabrication are often more beautiful than the intended patterns,” he wrote. The overall diameter of the sunflower is just 575 microns; the outer droplets are about eight microns in diameter and decrease to about one micron toward the center. Photo by Devin Brown.

ZINC OXIDE SPHERE This structure, which resembles a soccer ball, was formed from merged zinc oxide nanowires. These piezoelectric structures are normally used in nanogenerators to recover wasted mechanical energy but grew together to form this sphere. Image provided by Jamey Gigliotti and Zhong Lin Wang.
