Silver nanoparticles cause more damage to testicular cells than titanium dioxide nanoparticles, according to a recent study by the Norwegian Institute of Public Health. However, the use of both types may affect testicular cells with possible consequences for fertility.
Die Kryo-Elektronentomografie ermoeglicht hochaufloesende, dreidimensionale Einblicke in das Innere von Zellen. Jedoch koennen damit nur sehr kleine Zellen oder duenne Randbereiche groesserer Zellern direkt untersucht werden. Wissenschaftler vom Max-Planck-Institut fuer Biochemie haben jetzt eine Methode entwickelt, um in nahezu unzugaengliche Zellbereiche vorzudringen.
A Holy Grail of ultrafast science and technology is to image the changing structure of matter at the nanoscale during the interaction with light. An international collaboration used intense laser pulses delivered by the FLASH free-electron laser for X-ray scattering from nanoparticles. The goal was to look into ultrafast electronic processes during the nanoplasma formation where conventional spectroscopy techniques are inherently blind.
Scientists from the A*STAR Data Storage Institute have demonstrated the viability of fabricating soft magnetic thin films through electrodeposition, a plating technique that is scalable and can be performed at room temperature.
A team of Vanderbilt physicists reports that they have nailed down the source of the interference inhibiting the rapid flow of electrons through graphene-based devices and found a way to suppress it. This discovery allowed them to achieve record-levels of room-temperature electron mobility - the measure of the speed that electrons travel through a material - three times greater than those reported in previous graphene-based devices.
Since January Prof. Dr. Sotiris E. Pratsinis, winner of the award for research of the Alexander von Humboldt Foundation, is visiting scientist at the Universitaet Duisburg-Essen (UDE) from the ETH Zurich, Switzerland.
Two new studies performed at the U.S. Department of Energy's Argonne National Laboratory have revealed a new pathway for materials scientists to use previously unexplored properties of nanocrystalline-diamond thin films.
Merck and the Cluster of Excellence Engineering of Advanced Materials at Friedrich-Alexander-University Erlangen-Nuremberg (FAU) have today announced their cooperation in the field of new hybrid materials for more energy-efficient processes. This new strategic cooperation centers on catalytic conversion, gas purification and new functional surfaces.
Researchers at the National Nanotechnology Center (NANOTEC), Chulalongkorn University, and Stanford University have successfully synthesis titania nanoparticles and carbon nanotubes (CNT) using hydrothermal process to provide the highest photoconversion efficiency.
