The
article I chose was an article on Paul Chirik and his impressive research. Dr.
Chirik is a chemistry professor at Princeton who is studying alchemy. Alchemy
is a power or process of transforming something common into something special.
Alchemists centuries ago tried to change common metals such as iron or lead
into valuable metal such as gold or platinum. Dr. Chirik has developed his own
version of alchemy as he has learned to make iron function like platinum in
chemical reactions crucial to manufacturing. Platinum is a metal used to
manufacture every day life products such as denim and beer but it is also a
relatively scarce metal with a limited supply and a high price. The science
behind this development involves wrapping iron molecules in a ligand, which is
an organic molecule that alters the number of electrons free to form bonds and
it, also gives the molecule shape and that shape allows the iron to make these reactions.
Dr. Chirik has also worked with cobalt to produce different plastics using
inexpensive metals but this eventually proved inefficient because of the now
high price of cobalt after being needed in Ipads and Iphones. Scientists such
as Roderick Eggert support Dr. Chirik’s work with Eggert saying, “There’s a
broad appeal and logic to focusing on more abundant elements in designing
catalysts.” These catalysts usually use metals such as platinum, palladium, and
rhodium but these are all very expensive. In Dr. Chirik’s work with Iron, there
have been some issues such as the fact that iron rusts could make iron a
challenge to use in manufacturing. One other thing that Dr. Chirik and his
researchers are trying to accomplish is finding a way to use catalysts to
convert nitrogen that’s in the air into nitrogen that is used in products such
as fertilizer and carpet fiber. The research of Dr Chirik if developed could
have an enormous effect on human life.
The
development of ways to use inexpensive metals instead of expensive metals could
prove immensely valuable. For example, Dr. Chirik replaced platinum with iron
which is incredibly efficient because while a pound of platinum costs 22,000$ a
pound of iron costs only 50 cents. 50 cents is only .00002273 percent of 22,000
which when thought about is astonishing what using iron instead of platinum
could do. For manufacturing companies, that would save them an enormous amount
of money, so the price of production would decrease. With a drop in the price
of production comes a drop in the price of the product and that would affect
society because platinum is used to produce every day items like denim and beer
and more. This drop in price of products would increase allow more people to
buy these products and would increase the overall quality of life. Also, metals
such as platinum are much more scarce then iron and using iron instead of
platinum would stop platinum from running out in the long term which would be a
problem or if there was ever a problem in using platinum to develop products,
it would be good to have another way to produce this product such as using iron
instead as Dr. Chirik is. This research is being funded by major companies, as
it should because if successful, it would improve human life immensely. I chose
this article because I am very interested in Chemistry and was searching for a
Chemistry article and this one looked interesting from the preview.
This
article was on the whole well written and a good article. I thought that one
thing the article did well was it brought you into the article with an
interesting sentence which made me as a reader want to keep reading. It also
gave interesting facts that kept you interested throughout the article such as
the price of some of the metals used for production now compared to the price
of Iron. However, one area where I think the article could improve is the
explanation of the science behind Chirik’s scientific development. It gave a
brief overview, explaining what the iron mixes with but especially if you weren’t
a Chemistry student, it would be very hard to understand the explanation of the
Science. This would be an easy improve if the writer just took an extra
paragraph to explain the science and some of the terms he used in his
explanation. A second weakness in the article was the ordering of the facts
presented. The article went from Dr. Chirik’s iron/platinum development to his
other developments and then back to the problems in his iron development and
that was annoying as a reader. To improve this, I would have everything written
on the Iron development in one section and then everything else in it’s own
section.
