When it comes to churning out electrons, metal glass beats plastics

Field emission devices, which produce a steady stream of electrons, have a host of consumer, industrial, and research applications. Recent designs based on nanotubes and other nanomaterials embedded in plastics show initial promise, but have a number of drawbacks that hinder their wide-scale application. Researchers developed a promising and easily manufactured replacement for plastics: amorphous bulk metallic glass.

Tunnelling electrons under the microscope

Scientists have proved three years ago that so-called tunnelling ionization in helium atoms takes place without any appreciable time delay. They have now shown this is also true for more complex atoms. However, there are several significant effects that need to be taken into account here.

Carbon nanotube forest camouflages 3-D objects

A group of researchers from the University of Michigan is taking advantage of one of carbon nanotubes' unique properties, the low refractive index of low-density aligned nanotubes, to demonstrate a new application: making 3-D objects appear as nothing more than a flat, black sheet.

Ein Nanopartikel kommt selten allein

Nanomaterialien liegen in der Regel nicht als einzelne Partikel vor, sondern bestehen aus groesseren Einheiten in Form von Agglomeraten oder Aggregaten. Zu diesem Ergebnis kommt der englischsprachige Bericht "Dispersion and Retention of Dusts Consisting of Ultrafine Primary Particles in Lungs", den die Bundesanstalt fuer Arbeitsschutz und Arbeitsmedizin (BAuA) jetzt veroeffentlicht hat.
