Catalysis and Green Chemistry...

My key words were catalysis and green chemistry. It was hard finding articles about the key terms that I can understand (sad but true). The sites I tried included Google, Proquest, Sciencedirect.com and Wikipedia.

The first article was about catalysis for green chemistry, written by James Clark from the University of York's Department of Chemistry. I wasn't able to go through the whole article but it was about the use of heterogenization and how it can be used to get clean synthesis. The language was complicated with lots of professional terms like transesterifications and alkylation of aromatics. Because I wasn't able to understand half of the information, I wasn't sure how well the author backed up his argument. However, this article is very structured as the author moved from the beginning to the end of the catalyst heterogenization process. Personally, it was very confusing to read this article and I wasn't able to understand most of it.
From this article, I decided to find another one on "heterogenization" .Most of the results were about the application of heterogenization like "Heterogenization of a Chiral Bis(oxazoline) Catalyst by grafting onto Silica". The language once again was difficult to understand. The author had lots of demonstration to back up his article. The author divided up the article into different sections and since I wasn't sure what the whole thing is all about, I wasn't sure how the different sections fit together. I was confused and disappointed to read the whole thing because after looking through it, I wasn't able to get anything out of it.

My next article on catalysis and green chemistry was about Suzuki cross coupling reaction. It was a very long article and the language was composed mainly of chemistry terms. It had lots of references to back up the argument. The article was divided into different sections, starting with introduction so I thought it has good structure. I only read the first half of the article because I decided to move on. It was too hard to go through and I felt defeated after trying to read it.
After reading this article, I found another one about cross coupling reaction. This article is about cross-coupling in a body-translating reaction. The language was easier to understand than previous articles. It still, however, included lots of scientific terms. The article said that "interaural optokinetic stimulation reflects a gravitational cue" but there wasn't much info to back it up. The explaination was brief since it was more of a promotion for a new study, not a report of the study itself. Good structure, though. The article did flow from the introduction of the study to the conclusion the researchers came up with. I thought it was interesting but at the same time, it is not as detail as I would like it to be. However, because it was not as scientifically detailed as I expected, I was able to understand it.

My third article on the catalysis and green chemistry was about the role of catalysis in the development of green chemistry. It was from ScienceDirect and readers need to subscribe the article in order to read it. I only got my hand on the abstract but it looks interesting enough. From the abstract that is easy to read and persuasive, I'm a bit disappointed that I can't read the article itself. However, I did find another article on "pollution prevention" from the abstract of this article. Using epa.org, I found some information on how the pollution prevention (P2) got started and what the nation is doing to keep it going in order to protect our environment. It was easy to read. No overly-complicated chemistry terms. Since this article was more of spreading information, there was no clear argument involved. It was also a well-organized article that can be easily followed. I actually learned something from this article and that means alot!

My last article was about catalytic converter and how it can reduce the toxicity of emissions. It was from Wikipedia so it was easy to read and understand. I like how the article was organized into different categories, making it clear and not at all overwhelming. I enjoyed reading articles from Wikipedia. The article I found from this article was about automobile emissions control and how different technologies can reduce air pollution-causing emissions. It was a short article with simple language. There was no true argument but the article did give lots of example of how we can control car emissions. The article was organized into three different part with intro to what is automobile emissions control, what can be done to control car emissions, and where can it be done. After reading it, I felt motivated to do something to control emissions because there are ways to protect our environment. All it takes is to have people committed to it.

My ecological footprint is HUGE!!! ...

After taking the ecological footprint quiz, I knew I have to blog about it. This is crazy!!! Personally, I have always been considering myself to be someone who is very environmental-friendly. I recycle the majority of my "stuffs" like bottles, cans and paper. I eat fruits and vegetables whenever I can, which is like two or three servings a day. I cut out as much processed food as possible. Yet, my food acres are quiet big... Ok, it's huge! I carpool 96% of the time so it shows in the result of less than one acre. YAY!!! Shelter and goods/services are also big, each takes four acres, adding up to my footprint of 13 acres in total!!! Comparing to the average footprint in America, mine is quiet small, which I am very proud of. However, that still doesn't hide the fact that it would take 2.8 planets if everyone live like I do. Apparently, there is only one Earth so I can't afford to live like that. I guess it's time for a change. Based on "Stuff", I can become a vegetarian, take the bus or bike to Highline, reuse and recycle everything that I can. Surprisingly, that doesn't sound as difficult as I thought...Worth a shot!

On to the commute cost... My estimate cost of commuting for a month is about 267 dollars and about 3207 dollars a year. However, if I carpool with one person, it will cut the price down to about 1603 dollars yearly. If I vanpool with 6 other people for 5 days a week: $514. Ride the bus 1-zone: $594. Ride the bus 2-zone: $990. Compress workweek down to 4 days: $2565.60. Best of all, work at home: $0.00. It is amazing to see how much money I can save by using different alternatives to driving. That sure motivates people like me to do something about the way they commute daily. However, I don't have access to lots of these alternatives like working at home or compressing my workweek. In the end, I think it's all about getting out of my comfort zone and start living greener and wiser.

In the last quiz, my estimate annual electricity usage is about 45,872 kWh. The amount of greenhouse gas (CO2) we produce a year is 17,706 lbs, Nitrogen Oxides is 22 lbs, Sulfur Dioxide is 8 lbs, and mercury is about 145 millgrams. I was shocked by the result because my family is genereally careful about our electricity usage. We turn off our lights when we don't use them. We don't left the computers on overnight, either. Yet, the amount of CO2 my family alone produced yearly is so high. This makes me feel a little defeated because we are doing what we can and yet, it still isn't enough. How much will it take to make a difference?

THOUGHTS ON "STUFF" ...

It was overwhelming to digest "Stuff" but at the same time, eye-opening. I never really though about the food I eat, the clothes I wear or the thing I do in such a way before. Who knew that a 55-pound computer can generate 139 lbs of waste, 7300 gallons of water and 2300 kilowatt-hours of energy? Or that a mouthful of American food travels "1200 miles from farm to consumer"? I didn't. Too busy consuming , I didn't realize how much damages I can do to the environment. For example, every time I drive, I make a contribution to environmental pollution since gasoline is one of the main sources of CO2 emissions. Yet, there is a tiny sparkle of hope at the end of this quietly horrific book. "A sustainable North America is entirely possible..." There are solutions to the environmental issues that we are facing right now. It is up to us to find out what they are. This book is truly for everyone who cares about the land they live on and the future of our planet. Read it and start looking for the solution, people!
