Lec 1 - Impact of Tech (examples)

Question 1

Impact

Answer 1

Having an influence or effect

Question 2

Sustainability

Answer 2

“Sustainable development is the development that meets the needs of the present, without comprimising the ability of future generations to meet their own needs” - UN

Bottom line: Can we keep this up?

Question 3

Amphiphilic Surfactants

Answer 3

Molecules that have hydrophobic and hydrophilic ends.

Question 4

Top to Bottom Approach

Answer 4

Shape materials into useful forms traditionally. Start larger in size and shape/pare it down to a smaller size.

i.e. a bigger object undergoes processing and becomes a smaller object

Question 5

Bottom to Top Approach

Answer 5

Use small building blocks to construct nanoscale shapes. Start with atomic or molecular building blocks.

Question 6

Quantum Confinement

Answer 6

Quantum confinement is the phenomenon where the behavior and properties of particles, like electrons, are significantly altered when they are confined to a very small space.

Question 7

Surface Plasmon Resonance

Answer 7

A technique that measures changes in the way light excites electrons on a thin metal surface, causing them to collectively oscillate, and detects these oscillations to quantify the binding of molecules.

Question 8

Nanotechnology

Answer 8

Technology that engineers materials at the nanometer level.
