Blog Post 16: Dr. Matt Ray Presentation

1. Describe your observation of the common liquid in which he started his talk.
He talked about how milk is made up of the small fat cells which move around and can attach to eat other making it curdle.

2. Dr. Ray explain two ways in which keep small particles from sticking to themselves and aggregating in to large masses. He explained that the surface area of these particles is important to maintain to feel the benefits of the nanosize. Explain those two methods that he described.
Charge Stabilization - a colloid can only attract so many layers of ions before there is no attraction.

Steric Stabilization - by using certain polymers, you can prevent certain particles from attaching to one another.
