Mehr als 200 Interessierte aus Betrieben und Behoerden nahmen am Dialog-Forum 'Nanomaterialien am Arbeitsplatz' teil, das die Bundesanstalt fuer Arbeitsschutz und Arbeitsmedizin (BAuA) heute in Dortmund veranstaltete. Im Mittelpunkt der Veranstaltung standen Forschungsergebnisse und praktische Hilfestellungen der BAuA, die zum verantwortungsvollen Umgang mit Nanomaterialien am Arbeitsplatz beitragen.

Tiny gold particles are good for transferring heat and could be a promising tool for creating localized heating in, for example, a living cell. In new experiments, researchers at the Niels Bohr Institute have measured the temperature of nano-sized gold particles with extreme precision and have examined their ability to melt the lipid membranes surrounding cells, paving the way for dissolving sick cells.

Read moreAn 18-month NASA research effort to visualize the passenger airplanes of the future has produced some ideas that at first glance may appear to be old fashioned. Instead of exotic new designs seemingly borrowed from science fiction, familiar shapes - but built with high-tech materials - dominate the pages of advanced concept studies.

Electron microscopes are among the most widely used scientific and medical tools for studying and understanding a wide range of materials, from biological tissue to miniature magnetic devices, at tiny levels of detail. Now, researchers at the National Institute of Standards and Technology (NIST) have found a novel and potentially widely applicable method to expand the capabilities of conventional transmission electron microscopes (TEMs). Passing electrons through a nanometer-scale grating, the scientists imparted the resulting electron waves with so much orbital momentum that they maintained a corkscrew shape in free space.

Most of our Universe consists of hydrogen atoms, which are often found under extraordinarily high pressure as high as tens of millions of times the atmospheric pressure of Earth. Understanding the exotic physics of such a high-pressure regime will contribute to our understanding of planet formation, hydrogen storage, room temperature superconductivity and other fields, explains Toshiaki Iitaka from the RIKEN Advanced Science Institute in Wako.

Read moreNanopartikel spielen eine wesentliche Rolle bei der Entwicklung zukuenftiger diagnostischer und therapeutischer Methoden fuer Tumorerkrankungen, beispielsweise als Transporter fuer Wirkstoffe oder als Kontrastmittel. Aufnahme und Verteilung von Nanopartikeln im Tumorgewebe haengen dabei stark von der Partikelgroesse ab. Um dies systematisch untersuchen zu koennen, haben Wissenschaftler jetzt einen Satz fluoreszierender Nanopartikel verschiedener Durchmesser zwischen 10 und 150 nm hergestellt.

A new fractional vortex state observed in an unconventional superconductor may offer the first glimpse of an exotic state of matter predicted theoretically for more than 30 years. University of Illinois physicists, led by Raffi Budakian, describe their observations of a new fractional vortex state in strontium ruthenium oxide (SRO).
