Call it the anti-sunscreen. That's more or less the description of what many solar energy researchers would like to find - light-catching substances that could be added to photovoltaic materials in order to convert more of the sun's energy into carbon-free electricity.

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.

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).
