Carbon-coated Nanomagnets Could Be A New Form Of Cancer Treatment - ScienceDaily (May 17, 2008) — Carbon-coated nanomagnets may offer a new form of cancer treatment. Research presented at the 103rd Annual Scientific Meeting of the American Urological Association (AUA) suggests that nanoparticles consisting of metallic iron with a protective carbon coat could serve as a safe and effective hyperthermia agent. See also: Health & Medicine Prostate Cancer Skin Cancer Lung Cancer Matter & Energy Nanotechnology Biochemistry Organic Chemistry Reference Nanomedicine Metastasis Natural killer cell Embryonic stem cell Researchers from Germany have found that In animal models, using heat to selectively kill tumor cells is efficient. Using metallic iron in the nanoparticles (in lieu of iron oxide) would allow heating at greater temperatures; and coating the iron with carbon would prevent the iron from rusting, which can hinder the effectiveness of the therapy. In order to ensure that the nanoparticles did not harm non-cancerous cells, researchers tested their c....

Project on effect of metal coupling on rusting of iron Questions & Answers
Question : The zinc is actually chipped of. So why doesn't the iron rust?
Answer : It will, just give it some time. Even after chipping, the zinc metal will protect the very surface of the iron with a very thin layer of zinc atoms which must be removed first. Rain water will usually be able to accomplish this. There is also an electrochemical effect of the other zinc atoms in contact with the iron which will help prevent immediate oxidation of the iron. A drop or two of dilute acid on the exposed iron surface will show rust usually within 24 hours or less. Natural exposure may take a little longer.

Question : (Name all the metals that can rust, please.)
Answer : Steel is actually made from iron, so yes, it can rust. Some other metals (like aluminum) will oxidize.

Question : For example, what would be the chemical reaction (as simple as can be) of an iron nail rusting?
Answer : The rusting of iron is an electrochemical process that begins with the transfer of electrons from iron to oxygen.The rate of corrosion is affected by water and accelerated by electrolytes, as illustrated by the effects of road salt (calcium chloride) on the corrosion of automobiles. The key reaction is the reduction of oxygen: O2 + 4 e- + 2 H2O 4 OH- Because it forms hydroxide ions, this process is strongly affected by the presence of acid. Indeed, the corrosion of most metals by oxygen is accelerated at low pH. Providing the electrons for the above reaction is the oxidation of iron that may be described as follows: Fe Fe2+ + 2 e The following redox reaction also occurs in the presence of water and is crucial to the formation of rust: 4 Fe2+ + O2 4 Fe3+ + 2 O2 Additionally, the following multistep acid-base reactions affect the course of rust formation: Fe2+ + 2 H2O -> Fe(OH)2 + 2 H+ Fe3+ + 3 H2O -> Fe(OH)3 + 3 H+ as do the f..
