A University of Cincinnati research partnership is reporting advances on how to one day make solar cells stronger, lighter, more flexible and less expensive when compared with the current silicon or germanium technology on the market.
Researchers are investigating the manipulation of light in plasmonic nanostructures using the dephasing and population dynamics of electron-hole-pairs in metal coated, core-shell semiconductor nanowires. The technique would minimize energy loss and heat production.
Researchers designed a novel device based on graphene and metal nanoparticles that shows greatly enhanced response to light and is colour sensitive. This may foster applications like colour based ultra-sensitive photodetectors, efficient solar cells and detection of single molecules.
The overall goals of EFSA's Nano Network are to provide a forum for dialogue among participants; build mutual understanding of risk assessment principles; enhance knowledge on and confidence in the scientific assessments carried out in EU; and to provide increased transparency in the current process among Member States and EFSA on nanotechnology. All this with the aim to raise the level of harmonisation of the risk assessments developed in the EU on nanotechnology.
A way to link benzene rings together in a highly ordered three-dimensional helical structure using a straightforward polymerization procedure has been discovered, potentially opening up new areas of nanocarbon and materials science.
Delivering the capability to image nanostructures and chemical reactions down to nanometer resolution requires a new class of x-ray microscope that can perform precision microscopy experiments using ultra-bright x-rays from the National Synchrotron Light Source II at Brookhaven National Laboratory.
A material might melt or snap in half. And for engineers, knowing when and why that might happen is crucial information. Now, a researcher has laid out an overarching theory that explains why certain materials act the way they do.
Using their expertise in silicon optics, Cornell engineers have miniaturized a light source in the elusive mid-infrared (mid-IR) spectrum, effectively squeezing the capabilities of a large, tabletop laser onto a 1-millimeter silicon chip.
