Quantum effects can be seen at the atomic and nano levels. Why is nanotechnology more useful than atomic technology for creating new products?

A
It is too small for dangerous quantum effects to apply.
B
It is large enough to build controllable devices.
C
It is smaller than the atomic level.
D
It is too large for most quantum effects to apply.
4

A scientist is working with a new kind of quantum dot to make a dye. He is applying Newton’s laws to the particle, but it seems to be breaking these laws of physics. Which action will most likely help the scientist study the particle’s motion?

A
He needs to remember that the particle is too large for quantum analysis.
B
He needs to use quantum mechanics, not Newtonian mechanics, because this is a nanotechnology product.
C
He must determine new physical laws that only apply to quantum dots.
D
He must continue to use Newtonian mechanics, but he needs to learn more about the particle.
5

Nanotechnology and microtechnology devices are both very tiny. However, one property of nanotechnology distinguishes it from microtechnology. What is this unique property?

A
Nanotechnology can create new products.
B
Nanotechnology travels at the speed of light if needed.
C
Nanotechnology can display wave-particle duality.
D
Nanotechnology is not affected by gravity.
6

What is an important difference between nanotechnology and microtechnology?

A
Microtechnology shows results of quantum mechanics, but nanotechnology does not.
B
Nanotechnology is used to make products, but microtechnology is not.
C
Nanotechnology shows results of quantum mechanics, but microtechnology does not.
D
Microtechnology is used to make products, but nanotechnology is not.
7

An electronics company wants to improve the quality of its TVs. It wants a lighter, thinner screen that still provides a great image. Which nanotechnology product would most likely help the electronics company?

A
quantum dots
B
OLEDs
C
carbon wires
D
biomaterials
8

Chemotherapy is a cancer treatment that uses drugs to kill cancer cells. However, it is problematic, because the drugs also kill every healthy cell that they contact. How could nanotechnology best be used to improve the treatment of cancer with chemotherapy?

A
A quantum dot could be used to watch where the chemotherapy drugs go in the body.
B
Biomaterials could be made that would allow for cell growth within the cancer cells so that they are easier to find.
C
A nanometer-size carrier could be designed to bring the chemotherapy drugs only to cancer cells.
D
A nano carbon wire could be designed that would aid in the manufacture of chemotherapy drugs.
