Recently there has been research into fingerprint detection. There is a new device that can help determine an identity of a person using forensic metal fingerprinting. This device has been created at the University of Leicester. Dr John Bond's method of identifying fingerprints on brass bullet-casings, even after they have been wiped clean, was based on the minuscule amounts of corrosion which can be caused by sweat. Now Dr. Bond is applying this new technique to the industry by creating a machine which can measure corrosion. Corrosion is a process in which a solid is eaten away and changed by a chemical action. An example of corrosion would be as in the oxidation of iron in the presence of water by an electrolytic process. There is much research on inhibiting the corrosion of brass because of its use in heat exchangers and industrial pipe work, this technique enables the degree of corrosion to be easily measured.
This new technique affects humanity because this device makes it easier to measure corrosion on machine parts as well as making it easier for fingerprint analysis. Fingerprint analysis can be difficult to determine in some instances, but with this new device, fingerprint analysis can be determined earlier in the process.
Overall, I thought that this article was very interesting because there are many new developments in fingerprint analysis recently. I liked when Dr. Bond stated: "This is a new, quick, cheap and easy way of measuring the extent of corrosion on copper and copper based alloys, such as brass,”. This quote explains how this new machine effects humanity as well as why he created this device. I think that this article was well written as well as explained the process of fingerprint analysis with this new tool.

I liked how Alexandra introduced her article. She did this by saying the Dr John Bond of the University of Leicester discovered a new way to identify a person using forensic metal fingerprinting. I also liked how she explained what corrosion is. She made it possible for anybody to understand what she was talking about. Also, I thought it was good when she gave an example of corrosion.
Her review would have been if she mentioned if it is used a lot today or if it still being researched. She could also have done a better job by mentioning how metal fingerprinting is important.
I was impressed that fingerprints can be identified on brass bullet-casings even after they are wiped off. I never thought that was possible until I read her review.
I like the way she described the process. You didn’t need a lot of technical knowledge to understand how it worked. She explained it in a way that I understood and made me interested in the process. I also liked how she quoted the article when explaining we she was explaining why she liked the article. Not very many reviews quoted their sources even though in most other classes that is important in essays about books. So I think it is good that she used that quote. She also did a good job explaining the importance of the technique for the world and why the article was worth reading.
One thing she could have added was a critic of the article. There was a lot on why the article was important and good but nothing on how it could have been made better. She didn’t even mention what she thought of the article. She also could have given current examples of the process in use. Like an example of a real crime where it helped to catch the murder. There was a lot about the technique but very little on the practical application.
I was impressed by the fact that fingerprints could be recovered even after being wiped away. Most people think that wiping fingerprints makes them unrecoverable. But this article shows that very often your sin will find you out. It is a good thing that the most commonly used murder weapon can more easily be linked to the perpetrator of the crime.
