Scanning Electron Microscope image of flakes of graphite from common pencil lead. • SIZE: Scale bar representes 30 µm. • IMAGING TOOL: Scanning Electron Microscope (SEM)
This series of museum labels are designed for general use in your museum or institution to highlight existing connections to nanoscale science, engineering, or technology. NISE Net partners are already coming up with creative ways to use these labels to showcase nano. For example, you can make a scavenger hunt or special tour to encourage visitors to find all the connections! Additional templates (.doc and .indd) are also provided so that you can create your own signage and content.
In this episode of O Wow Moments with Mr. O from the Children's Museum of Houston, we take a look at a Nobel Prize winning experiment!
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.
Associate Professor of Mechanical Engineering & Materials Science at Yale, Dr. Ainissa Ramirez, discusses how a layer of carbon that is one atom thick, called graphene, will revolutionize our lives.
"Exploring Materials - Graphene" is a hands-on activity in which visitors use tape and graphite to make graphene and test the conductivity of graphite. They learn that graphene is a single layer of carbon atoms arranged in a honeycomb pattern. There are two versions of this activity, one that uses an LED to test the conductivity and one that uses a buzzer.
"Explore Science - Zoom info Nano Draw a Circuit" (2016) version designed for groups and community outreach.
