First fly into the air
Odorous molecules are usually volatile and can enter the air from the surface of food, flowers or perfume, and then be inhaled into the nasal cavity.
If the structure changes, the smell may change
Carbon chain length, functional groups and spatial configuration all affect the volatility of the molecule and the way it binds to the receptor. Changing just one atom can result in a completely different aroma.
Scent is an ensemble of molecules
Natural odors are often made up of many molecules. Perfumers and food chemists study their ratios, release rates and interactions.
A very approachable introduction to the topic.
This connects the classroom concept with a real application nicely.
The explanation of the mechanism was especially helpful.
Looking forward to reading more about the engineering challenges.
This gave me a useful starting point for further research.
The structure is clear and the pacing works really well.
This is a wonderfully clear way to explain a complicated idea.
Saved this one for a deeper discussion with my classmates.
I had never thought about the material side of this problem before.
