Unexpected Properties

NISE Network product
Description: 

This exhibit demonstrates how materials at the nanoscale can have unexpected properties. The tabletop interactive, Quantum Dots, focuses on the property of color and how a material’s color may change when brought down to the nanoscale. Visitors alter the size of a magnified quantum dot and watch the light that it emits shift from red to blue as it shrinks to a fraction of a nanometer. The copy panel and side monitors explain how unexpected properties are being used in real-world applications of quantum dots and nanoparticles, from medical imaging to consumer goods.

Objectives

Big Idea: 
Super small nanoparticles can have very unexpected properties.
NISE Net Content Map: 
  • Nanometer-sized things are very small, and often behave differently than larger things do.
  • Scientists and engineers have formed the interdisciplinary field of nanotechnology by investigating properties and manipulating matter at the nanoscale.
  • Nanoscience, nanotechnology, and nanoengineering lead to new knowledge and innovations that weren't possible before.
