Using self-assembly to make molecule-sized particles with patches of charge

Physicists, chemists and engineers at the University of Pennsylvania have demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules that may one day serve as drug-delivery vehicles to combat disease and perhaps be used in small batteries that store and release charge.

New material could boost data storage, save energy

North Carolina State University engineers have created a new material that would allow a fingernail-size computer chip to store the equivalent of 20 high-definition DVDs or 250 million pages of text, far exceeding the storage capacities of today's computer memory systems.

0.2 second test for explosive liquids

New research explains how a new form of spectroscopy, a scientific method that uses electromagnetic radiation to identify materials, and a novel nanoelectronic device to detect signals, can identify explosive liquids, or liquid components for the fabrication of explosives, in usual plastic bottles almost instantly.

Die meisten Deutschen haben keine Vorstellung von Nanotechnologie

Die Nanotechnologie weckt diffuse Hoffnungen. Ihr Nutzen wird vom ueberwiegenden Teil der Deutschen hoeher eingeschaetzt als die moeglichen Risiken. Gleichzeitig hat nur ein geringer Teil der Bevoelkerung eine klare Vorstellung davon, was unter dem Begriff ueberhaupt zu verstehen ist.

New material provides a key to explaining superconductivity

Nobody knows exactly why some materials suddenly become superconductors below a certain temperature. Researchers at Helmholtz-Zentrum Berlin fuer Materialien und Energie (HZB) present new findings that could finally resolve a long-standing dispute as to which theory is correct.

Argonne scientists find new set of multiferroic materials

The trail to a new multiferroic started with the theories of a U.S. Department of Energy's Argonne National Laboratory scientist and ended with a multidisciplinary collaboration that created a material with potential impact on next generation electronics.

Bio-scaffold may help humans replace lost or missing bone

Mother Nature has provided the lizard with a unique ability to regrow body tissue that is damaged or torn - if its tail is pulled off, it grows right back. She has not been quite so generous with human beings. But we might be able to come close, thanks to new research from Tel Aviv University.

New technique paves way for medical discoveries

Researchers have previously been able to analyse which sugar structures are to be found on certain proteins, but not exactly where on the protein they are positioned. This is now possible thanks to a new technique developed at the Sahlgrenska Academy at the University of Gothenburg, Sweden.
