Week 4 homework: Just how close are we to a Green Economy?

Green Economy/Green Chemistry is good.

It's dreamy.

It tries to make chemical production harmless and energy efficient.

It makes the relationship between us and the Planet better.

But we just began the story.

Nowadays, many big companies, regardless chemical related industry or not, are investing on Green Chemistry.

Some of their investments are doing great! 

But not all nations can deal with Green Chemistry, in reality.

Many countries are still developing--their current goal is not how to make chemical production safer, but how to grow and thrive! 

For example, India is trying to start Green Chemistry, but before that a lot of problems are waiting to be solved.

In this kind of case, developed country can help them out.

There must be many investment opportunity with them.

It's a long term story, but eventually, we'll make it! 

Let's give it a shot! 

Week 4 Homework: Catalyst of the Week

"Mentos Coke"

Putting Mentos into Coke will stimulate "blasting power" of carbon dioxide of carbonated water.

The mechanism is following:

1)   the gelatin and gum arabic from Mentos break the surface tension

2)  Each Mentos has thousands of tiny pits all over the surface.  These are perfect for carbon dioxide bubbles to form

3)  As soon as the Mentos hit the soda, bubbles form all over the surface of the candy. 

4) Since surface tension is weaken by step 1), carbon dioxide bubbles created on the surface of Mentos is now easy to blast out

5) Since cap of Coke bottle is small, it enhance the blasting power of CO2 gas.

6) Blasting like Youtube movie on the top of this article occurs.

Week 3 homework: review of "Neptune Medicine Chest"

William Fenical is a scientist.

He is founder of newly established company "Nereus Pharmaceutical Inc."

He mainly studied for bacteria in ocean.

One of his research achievement is patented and sold to cosmetic company Estee and bring $680000 to UC system, which is top 10 of all UC patent.

He wants to continue to study for ocean bacteria so that he can find the bacteria that can cure/resist cancer, eventually patented and produced by pharmaceutical industries.

I think it is definitely dreamy story.

His Nereus Pharmaceutical is currently being secured by stock holder.

It costs a lot of money, so things are not that easy to go along, but I hope his story will eventually become real and help human being health!
