Nanomagnete aus der Röhre

Forschern ist es gelungen, magnetische Nanokristalle im inneren Hohlraum von Kohlenstoff-Nanoröhren zu züchten. Diese weisen drei Besonderheiten auf: (1) Die Grösse der Kristalle lässt sich durch den Durchmesser der Nanoröhre kontrollieren. (2) Die Kristalle sind vor Oxidation geschützt. (3) Durch ihre Winzigkeit haben die Nanokristalle andere magnetische Eigenschaften.

Pollution control with nanotechnology

In the remediation of pollutions in the soil and groundwater, minute nanoparticles are being increasingly used that are to convert resp. break down pollutants on site. The process, often somewhat mistakenly described as 'nano-remediation', can also be used with contaminations that have been hard to fight up to now, for example through heavy metals or the notorious, carcinogenic softener PCB. Yet how do the various nanoparticles behave in the earth, are they in turn harmless for humans and the environment and how can they be produced at a favourable price?
