This illustration shows how an Atomic Force Microscope (AFM) is used to image a line of graphene made by a pencil. The scale spans ten orders of magnitude, from the microscope and pencil to the atoms that compose the scanning probe and pencil line. As the viewer zooms into the line, graphite flakes, and eventually a single layer of graphene, become visible. On the AFM, a silicon cantilever with a sharp atomic tip and a laser with a photodiode measure the up and down motion as the probe maps out the graphene sample.
These colorful educational posters cover all four NanoDays key concepts. Use the posters to help decorate and define the space for your NanoDays event, call attention to specific activities or programs, and provide additional content to visitors.
A seminar designed for early-career scientists about the successful design and use of scientific posters.
Set of cartoon posters on the possibilities of nanotechnology developed by Jive Media Africa funded by the Department of Science and Technology through South African Agency for Science and Technology Advancement (SAASTA). Poster topics include water purification, cancer treatment, and energy. A learner handbook with classroom lessons and worksheets accompanies the posters.
This formative evaluation looks at the second version of a poster created to help visitors visualize the nanoscale structures in a butterfly wing. This version includes annotations to call out the different structures of the butterfly wing and reflects changes made to better align the illustration with scientific content.
