Friday Photo: Pencil Pusher
Posted in: UncategorizedThat only looks like a glam ’70s coffee table. It’s in fact the craggy surface of graphite (dotted with catalyst and inhibitor particles), as seen through the scanning electron microscope of Heinrich Badenhorst. The University of Pretoria scientist is among the winners of the Carl Zeiss Nano Image Contest, which challenged users of the German company’s ion and electron microscopes to submit their most amazing images of incredibly tiny things. Badenhorst’s image received the most online votes in all four categories. Other top finishers were Munich Technical University doctoral students Norman Hauke and Arne Laucht, who captured this image of a nanoscale photonic crystal, and Andrey Burov of the Russian Academy of Sciences, who went for the gold with a transmission electron micrograph of golden nanoparticles. Meanwhile, Dutch researcher Emile van Veldhoven triumphed in the helium ion microscopy category by getting crafty with logos that are invisible to the naked eye. He etched three-dimensional logos of his home institutions (Delft Technical University and the TNO Institute) and that of Carl Zeiss (suck up) on a two micrometer-square surface and then snapped this photo.
