Hello, I'm Materialscientist. I noticed that you recently removed some content without explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry: I restored the removed content. If you would like to experiment, you can use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks!

Please refrain from making unconstructive edits to Wikipedia, as you did at Electronic nose. Your edits appear to constitute vandalism and have been reverted or removed. If you would like to experiment, please use the sandbox. Thank you. Dawnseeker2000  13:56, 20 July 2013 (UTC)
