Carbon Nanotubes als Spinfilter

Alle Elektronen tragen ein magnetisches Moment, Spin genannt, das grundsaetzlich in zwei Richtungen zeigen kann. Setzt man geeignete Nano-Roehrchen aus Kohlenstoff einem hohen Magnetfeld aus, so lassen sie bei einem bestimmten Wert nur Elektronen mit einer Spinrichtung durchfliessen. Erhoeht man das Magnetfeld weiter, so werden nur Elektronen mit der anderen Spinrichtung durchgelassen.

Iron oxide nanoparticles becoming tools for brain tumor imaging and treatment

Tiny particles of iron oxide could become tools for simultaneous tumor imaging and treatment, because of their magnetic properties and toxic effects against brain cancer cells. In mice, researchers have demonstrated how these particles can deliver antibodies to implanted brain tumors, while enhancing tumor visibility via magnetic resonance imaging (MRI).

Livermore's dynamic transmission electron microscope (DTEM) earns innovation award

An innovation that can help scientists observe a reaction moving at greater than 10 meters per second, with a few nanometers spatial resolution, is a feat some would say is nearly impossible. But not the Lawrence Livermore team of scientists who developed the dynamic transmission electron microscope (DTEM).
