New models help introduce the blind to careers in nanoscale science and engineering
When it comes to research at the nanoscale, vision is not necessarily an advantage. The subjects are so small, no one can see them. To encourage people with visual impairments to pursue fields in nanotechnology, educators have developed a way to craft accurate, detailed and touch-friendly models of nanoscale objects like carbon nanofibers, allowing the students to "see" those objects for the first time.
While students have learned from abstract models of chemical structures for decades, the new technique creates 3-D versions of objects as they actually are.
Developed by educators at the University of Wisconsin-Madison (UW-Madison), the models are about the size of a textbook and are formed using rapid prototyping, a process that "prints" 3-D objects. Each model is a scaled-up replica of tweaked data from a scanning electron microscope. The creators hope they will soon be able to apply the same process to data from other instruments, including the patterns of atoms revealed by atomic force microscopes.-National Science Foundation
