Scholars,
As we move through the protocol for scientific method this week, we realize how important it is to study other scientific research before conducting our own. For this weeks online assignment I would like you to find a Chemistry article (periodical) (of your choice of topic) online, make sure the link to the article is in your post and discuss/sumarize the research you found.
(ABSTRACTS ARE OK but full text is preferred)
Here is a hint: go to google, at the top of the page click more... then click scholar then all you have to do is type in the topic of your choice.
Mr. D

This article was about chemists who tested a rule about how fast cetain chemicals can transfer through a cell wall. What they had been taught and been told for about a century was actually incorrect and the rate that chemicals pass through a cell wall was in fact much slower. They are going to use this procces to test the diffusion of cells with a variety of chemicals.

African Chemists role in Health Care
This article was about the role that African Chemists play in Health Care in developing countries. Basically they provide medicines for self-diagnosed illnesses.

Pauling and Sickle Cell Anemia
The First Condition Described as a Molecular Disease
This article was about how this chemist Linus Pauling was studying about hemoglobin which basically helps red blood cells travel throughout the body and how the hemoglobin interacts with oxygen. He later found out that his studies were useful when the disease sickle cell anemia. He started looking into the hemoglobin of someone with sickle cell anemia and one without and found that it was different. Basically what happened was that with his studies of the hemoglobin he helped to learn more about the disease of sickle cell anemia.

This aritcle was about scientist at The University of Manchester who devolped a new and fast way of making biological or protein chips. These chips collect important data about the behavoir of proteins. This new technology could possibly lead to disease detection and drug discovery.

This article was about the different types of chemical reactions. Chemical reactions are characterized by the type of chemical changes. There are 6 types of basic chemical reactions which are synthesis, decomposition, single replacement or displacement, combustion, and acid-base. The other types of chemical reactions are organic which involves having carbon as the major element.

This article is about fingerprints, and how much more information you can get from them, besides someones identity. Traces of chemicals from drugs can be found, and from explosives which could help spot terrorists. You can also find out if you have a disease that can't be found from a blood or urine test.

The article was about how the ice in the northwest passage was at an all time low, and how usually this time of year the ice had not fully melted. It has not been on record this low in 30 years. The concern is that methane which is released form the melting ice, unlike carbon dioxide can create a non-linear warming trendbe the result of global warming.

This article was about chemical bonds an how it forms wen electrons of different atoms interact with each other.

This article is about using alternative to using petroleum to make the back sheets for solar panels. The company BioSolar would start off used cotton rags and them into a film of the natrual fiber celluse. Then they would blend the film with a particular type of nylon made from castor beans. And studies show from the national renewable energy laboratory show that this back sheet last as long maybe even longer than petroleum made back sheets

The article i read was about how silcone surfaces is created. Silocone surfaces was discovered in 1986 and is the reason for the scanning tunning microscope. It is created through a number of chemical proccesses.

This article was about chemical weathering.Chemical weathering has 4 categories of reactions and these are the changes in the structure and composition of the rock.Chemicals also have a part in this too.

This article was about carcinogens from car exhaust. Scientists discovered that if the carcinogens mix with nanoparticles, they can be as dangerous and toxic as cigarette smoke. The particles can linger in the air, car exhaust pipe, or catalytic converter.

This article is about how scientists have come up with a way for people with Celiac Sprue to be able to eat the food grains that were originally toxic to patients w/ Celiac Sprue by introducing a specific peptide to detoxify the food grains.

This article was about engineers at Georgia Tech that used skin cells to create artificial bones. These bones copy the ability of natural bone to blend into other tissues such as tendons or ligaments.

This article is about a team of researches that have found a trough known as "Cayman Trough" they have been rewarded money to search this trough for any different sea forms. They hope they will find keys to help with significant pieces to the puzzle.

This article explained how atoms link to other atoms through chemicals bonds. There are two types of chemical bonds, either ionic bonds or covalent bonds. Ionic bonds are when an atom accepts or donates a valence electron,where as a covalent bond is when an atom shares a valence electron.

"Drinking water safe after China plant blast"
This article was about a chemical plant bursting in southern China.the chemicals that was in the plant included acetylene, ethylene, methanol, vinyl acetate and polyvinyl alcohol. It killed 20 workers and injured 60 workers...but 4 dams were put up not allowing polluted water to flow in local rivers

This article is explaining electronegativity and things relating to it. This article states that electronegativity is a measusre of the attraction that an atom has for the bonding pair of electrons in a covalent bond. The Pauling scale and the Mulliken scale are used to record electronegativity.
