Class Quiz – Green Chemistry

1. Do you consider Green Chemistry to be an effective Social Movement?

I do, because something has to start changing.  I think that it can be a wonderful social movement if more people were aware of it.  But as for now, it seems that until all the resources are used up or destroyed, the powers that be will keep doing what they do.  But everything has to start somewhere, and it seems like the mindset is where it should be, now we just need to bring humanity up to speed.

2. Suppose you could enforce the Twelve Principles of Green Chemistry, which principles would you choose to prioritize?

1-Design safer chemicals and products

2-Prevent waste

3-Design less hazardous chemical syntheses

3. Given J&J are now withdrawing sales of their talcum powder in the U.S. – generally, do we have adequate health and safety controls, in your view? (J&J to still sell baby powder in UK despite US ban)

I do not think we have adequate health or safety controls here or just about anywhere.  We get rid of talcum powder but still import farmed salmon that are banned in Third World Countries.  That is just one example of little care goes into the health of our foods or how close anyone is looking at safety controls.

Week 3 - Green Chemistry

I really like the idea of green chemistry, but like with most things,  what will the waste product be?  It seems that there are almost always a product of mixing and making things,  so the concern is what will the new bi-product be of green chemistry.   Will we think it is is green and safe now, but a decade or two down the road we are back in the same spot from where we started?  Trying to figure out what to do with all our waste.....

Week 3 - My element - Lithium

Lithium

Atomic #3

Melting point

180.50°C, 356.90°F,   453.65 K

It is the lowest density of all the metals. 

The most important use of lithium is in rechargeable batteries for mobile phones, laptops, digital cameras and electric vehicles. Lithium is also used in some non-rechargeable batteries for things like heart pacemakers, toys and clocks.

Lithium metal is made into alloys with aluminum and magnesium, improving their strength and making them lighter. A magnesium-lithium alloy is used for armor plating. Aluminum-lithium alloys are used in aircraft, bicycle frames and high-speed trains.

Lithium oxide is used in special glasses and glass ceramics. Lithium chloride is one of the most hydroscopic materials known, and is used in air conditioning and industrial drying systems (as is lithium bromide). Lithium stearate is used as an all-purpose and high-temperature lubricant. Lithium carbonate is used in drugs to treat manic depression, although its action on the brain is still not fully understood. Lithium hydroxide is used as a means of storing hydrogen for use as a fuel.

It gets its name from "lithos," the Greek word for stone.

It is a mineral and trace amounts can be found in almost all rocks.

It is used in medications to help treat mental illnesses.  Bipolar disorder, depression, and schizophrenia.  They don't really know how it works, but they think it increases chemical messengers in the brain.

Class Quiz – The Cultural Influence of Chemistry

1.    “It's also a valuable reminder that requesting natural or naturally-derived ingredients in place of synthetics may result in them coming from unexpected places.”
    (7 gross ingredients found in cosmetics)
    Any surprises from this article?

I was not totally surprised by this article as I was already under the assumption that terrible ingredients were in there.  I had a classmate whos proffession was cosmetology, and she would talk abotu how you really need to read the ingredients of make up because most are just filled with very un-natural products.








2.     Do you expect our focus on reducing our carbon footprint will be changed now?

I sure hope so!  I was actually just looking at before/after pics on the internet of major cities with as much as 50% decrease in smog.  The waters are cleaner, the air is cleaner, so I would hope that this is a good little wake up call to the whole world.  But do i expect that this will be a focus when things start goingback to normal, no I don't.  People will just want to get back to what they were doing.









3.     “Cultured Meat” – yummm! – what is your take?


Well, there will have to some sunstitute happening at some point.  If they were smart about it,  they would leak it out little by little, or even start mixing it with real meat, so that over time, we won't even know the change has been made.  I was just reading how 200,000 pigs per day are not being slaughtered,  that up to 1 million per week that will have no use and just be killed because there is no one to take care of them, so, there has to be a balance.

Week 1

Hello!  I am Scott and I am a 3rd year student at ACCHS.  I live in SF and have for the past 18 years, I love this city even though it has gone through many changes that may not always be for the best,  but that is SF.

I am very excited to be in another Larry Spears class, I really like his style and he also brings such great topics and awareness to the class.  So thank you Larry!  Any questions,  feel free to ask!
