For years, scientists have been trying to create special materials with a negative refractive index - their optical properties are quite different from those of normal materials. Researchers at the TU Vienna could now show that even common metals can have a negative refractive index, if they are placed in a magnetic field.
A team led by researchers at Stanford and Harvard universities has not only created a new material for high-speed organic semiconductors, it has come up with a new approach that can take months, even years, off the development timeline.
Swapping the chemical groups that originally coat iron oxide nanoparticles and making the particles soluble in biological solvents shows great promise for medical applications, such as drug delivery and contrast agents.
Researchers are able to achieve extremely high-resolution microscopy through a process known as stimulated emission depletion (STED) microscopy. This cutting-edge imaging system has pushed the performance of microscopes significantly past the classical limit, enabling them to image features that are even smaller than the wavelength of light used to study them.
YoungNanoProfessionals (YNP), eine Initiative der Aktionslinie Hessen-Nanotech, des NanoNetzwerkHessen und der DECHEMA vernetzt junge Wissenschaftler auf dem Gebiet der Nanowissenschaften und bietet Ihnen eine Plattform zum intensiven Austausch ueber aktuelle Forschung und Entwicklungen im Nano-Business, berufliche Aussichten und die Ergebnisse der Sicherheitsforschung an Nanomaterialien.
Entanglement between two atomic systems is very fragile and up until now researchers have only been able to maintain the entanglement for a fraction of a second. But in new experiments at the Niels Bohr Institute researchers have succeeded in setting new records and maintaining the entanglement for up to an hour.
Researchers from North Carolina State University have developed a simple, scalable way to align gold nanorods, particles with optical properties that could be used for emerging biomedical imaging technologies.
Jackie Y. Ying and her former group member Jun Yang from the A*STAR Institute of Bioengineering and Nanotechnology have now developed a metal-semiconductor nanocomposite that can improve the performance of fuel cells.
Mingyong Han at the A*STAR Institute of Materials Research and Engineering and co-workers have now discovered a way to produce high-quality nanoscale heterojunctions, setting the stage for cheaper and more efficient photovoltaic devices.
Scientists can now look deeper into new materials to study their structure and behavior, thanks to work by an international group of researchers led by UC Davis and the Lawrence Berkeley National Laboratory.
