Science Daily: Graphite Mimics Iron's Magnetism: New Nanotech Applications.
ScienceDaily (Oct. 5, 2009) — Researchers of Eindhoven University of Technology and the Radboud University Nijmegen in The Netherlands show for the first time why ordinary graphite is a permanent magnet at room temperature. The results are promising for new applications in nanotechnology, such as sensors and detectors. In particular graphite could be a promising candidate for a biosensor material. The results will appear online on 4 October in Nature Physics.As usual, WikiAnswers is on the case.
