Researchers have taken a leap forward towards a deeper understanding of an undesired effect in thin film solar cells based on amorphous silicon - one that has puzzled the scientific community for the last 40 years. The researchers were able to demonstrate that tiny voids within the silicon network are partly responsible for reducing solar cell efficiency by some 10 to 15 percent as soon as you start using them.
McDermott Will and Emery offer their Special Report '2013 Nanotechnology Patent Literature Review: Graphitic Carbon-Based Nanotechnology and Energy Applications Are on the Rise' as a continuing study of trends observed in our 2013 and 2012 reports, and also present a renewed focus on trends in the energy sector.
Using a superfluid atomtronic circuit, physicists have demonstrated a tool that is critical to electronics: hysteresis. This is the first time that hysteresis has been observed in an ultracold atomic gas.
Joint research on super-resolution microscopy from the National Physical Laboratory (NPL) and the University of Cambridge has been selected as a highlight of 2013 by the Journal of Optics, making it freely available to view online.
The Spanish foundation BBVA honors Haider, together with Prof. Harald Rose, senior professor at Ulm University, and Prof. Knut Urban, Forschungszentrum Jülich, for the development of a new generation of so-called aberration-corrected electron microscopes that reach resolutions in the atomic range.
According to Fourier's law, heat spreads evenly throughout a system. For two- and one-dimensional objects such as films or the finest of wires, however, other rules seem to apply. Scientists have now pinned these down.
Molecular physicists from Radboud University Nijmegen have produced images of the changes in direction of colliding nitrogen monoxide molecules (NO) with unprecedented sharpness. By combining a Stark decelerator with advanced imaging techniques, they were able to obtain very high resolution images of the collision processes.
Scientists have discovered that a polymer can provide a key to get into tumors: They have developed a new paradigm to home nanoparticles, containers that measure a few 100 nanometers in size, to endothelial cells.
