Nanoconcepts and Simulations

Nanoconcepts represent self-contained instructional materials focusing on the key ideas in nanoscale science and engineering (NSE) and their applications. Each Nanoconcept contains a general user introduction, main concept, notes, images and/or simulations. A usage guide and connections to general science concepts is also provided to aid integration into the classroom.

Nanocos: The Card Game of Nanotechnology Concepts
Submitted on 17-JAN-07
Contributed by

Nanocos is a highly interactive card game that encourages students to learn important science concepts and their role at the nanoscale. Combining both the entertainment of popular card games with the educational value of nano-concepts, Nanocos will appeal to both students and educators alike. Contained within each attractively-decorated card is a scientific concept that forms the basis of modern nanotechnology. Because of the varying levels of complexity that unfold during each game, students wi...

 

Band Structure of Carbon Nanotubes in a Perpendicular Electric Field - Version 2.0
Submitted on 04-JAN-07
Contributed by Umberto Ravaioli

This interactive simulator performs band structure calculations for zigzag and armchair type carbon nanotubes (CNT) using the nearest-neighbor tight-binding method with a hopping potential of ? 2.5eV. Effects of curvature are not included in the model. A uniform electric field perpendicular to the axis can be applied, causing degenerate eigenvalues to split (Stark effect)......

 

Cube Building - Interactive Computational Animations on Nanomaterials
Submitted on 14-NOV-06
Contributed by Richard Braatz, Mitsuko Fujiwara, Limay Goh, Effendi Rusli, Valerie Maynard

This animation introduces the importance of surface area to volume ratio in nanoconcept. As bigger cubes are built, the SA/V ratio decreases. Smaller particles have higher SA/V ratio, which is an importance property for many chemical processes....
