Does designing a
material on the
nano or molecular
scale really do
anything productive
on our
level?
Updated September 2011
By engineering an alloy on the atomic level, the metal
gains a list of novel properties that can be used in
several applications.
Visit http://www.liquidmetaltechnologies.com to learn
more about a commercial application of this process.

LiquidMetal alloy has no ordered crystalline structure
This
engineered
alloy has an
amorphous
structure. This
means it has
no discernable
pattern in its
atomic
arrangement.

Elastic Strain Demo
Gather several types of metals to
compare with the new alloy:
•Aluminum
•Brass
•Copper
•Steel
•Titanium
Collect a clear tube, steel ball and a
timer to time the bounces.

Elastic Strain Demo
1. Drop the steel ball from the same height on
each type of metal.
2. Count the number of bounces and record
them.
3. Use a computer recording software to
record the bounces and time.
4. Draw a bar chart displaying the bounces for
each metal.
5. Discuss applications for a metal that repels
forces, doesn’t rust, and has low friction.
Updated September 2011
This is a set of
audio recordings
of several metals
bounce test.
It is easier to
count the
number of
bounces visually
rather than
audibly.

This module is one of a series designed to introduce faculty and high school
students to the basic concepts of nanotechnology. Each module includes a
PowerPoint presentation, discussion questions, and hands-on activities,
when applicable.
The series was funded in part by:
The National Science Foundation
Grant DUE-0702976
and the
Oklahoma Nanotechnology Education Initiative
