Wie von Geisterhand: Programmierte Nanopartikel organisieren sich zu hochkomplexen Nanostrukturen

Zellen von Pflanzen und Tieren sind ein prominentes Beispiel dafür, wie die Natur - ausgehend von molekularen Strukturen des Erbguts - in einer zielgerichteten, vorprogrammierten Weise immer größere Einheiten aufbaut. Die Nanotechnologie versucht dieses Bottom-up-Prinzip zu kopieren, indem sie die Fähigkeit von Nanopartikeln zur selbständigen Strukturbildung nutzt.

Testing nanomaterial smart plastics in real time

Nanoparticle additives can make plastics scratch and flame proof, or give them antibacterial properties. For this to work, the particle distribution within the plastic compound must be absolutely correct. A new device is now able to test the distribution in real time.

Organic lights and solar cells straight from the printer

Flickering façades, curved monitors, flashing clothing, fluorescent wallpaper, flexible solar cells - and all printable. This is no make-believe vision of the future; it will soon be possible using a new printing process for organic light-emitting diodes.

Researchers discover important mechanism behind nanoparticle reactivity

An international team of researchers has used pioneering electron microscopy techniques to discover an important mechanism behind the reaction of metallic nanoparticles with the environment. Crucially, the research shows that oxidation of metals - the process that describes, for example, how iron reacts with oxygen, in the presence of water, to form rust - proceeds much more rapidly in nanoparticles than at the macroscopic scale.

NanoSafety Cluster launches its first newsletter

The NanoSafety Cluster is an EC initiative to maximise the synergies between the past, ongoing and future FP7 nanosafety projects. Each of these projects addresses key aspects of nanosafety, including toxicology, ecotoxicology, exposure assessment, risk assessment, standardisation, and mechanisms of interaction.

New approach produces cleanest graphene yet, with previously unrealized performance

Columbia Engineering researchers have experimentally demonstrated for the first time that it is possible to electrically contact an atomically thin two-dimensional material only along its one-dimensional edge, rather than contacting it from the top, which has been the conventional approach. With this new contact architecture, they have developed a new assembly technique for layered materials that prevents contamination at the interfaces, and, using graphene as the model 2D material, show that these two methods in combination result in the cleanest graphene yet realized.
