Physicists at ETH Zurich have demonstrated one of the quintessential effects of quantum optics - known as the Hong-Ou-Mandel effect - with microwaves, whose frequency is 100000 times lower than that of visible light. The experiment takes quantum optics into a new frequency regime and could eventually lead to new technological applications.
Three-dimensional magnetic vortices were discovered by scientists from the Helmholtz-Zentrum Dresden-Rossendorf together with colleagues from the Paul Scherrer Institute within the scope of an international cooperation.
Seeing the fine-scale properties of materials relevant to nanotechnology is a prominent challenge that currently can be met only under ideal conditions. Coherent X-ray imaging promises to greatly expand the range of materials and environments in which these important properties can be observed.
Researchers from Ulsan National Institute of Science and Technology (UNIST) demonstrated high-performance polymer solar cells (PSCs) with power conversion efficiency of 8.92% which is the highest values reported to date for plasmonic PSCs using metal nanoparticles.
Researchers at CRANN, Ireland's leading nanoscience institute, funded by Science Foundation Ireland and based at Trinity College Dublin, have discovered a new concept in sensor-development. The research provides a completely new platform for the development of sensors worldwide and will lead to low-energy, remotely powered sensors that have greater detection capacity than those currently available.
Researchers deformed mirrors in order to disrupt the regular light path in an optical cavity and, surprisingly, the resulting chaotic light paths allowed more light to be stored than with ordered paths.
The new material's artificial 'atoms' are designed to work with a broad range of light frequencies. With adjustments, the researchers believe it could lead to perfect microscope lenses or invisibility cloaks.
Scientists have discovered highly conductive polymer behavior occurring at a polymer/nanocrystal interface. The composite organic/inorganic material is a thermoelectric and has a higher performance than either of its constituent materials. The results may impact not only thermoelectrics research, but also polymer/nanocrystal composites being investigated for photovoltaics, batteries, and hydrogen storage.
A team led by Professor Keon Jae Lee from the Department of Materials Science and Engineering at KAIST has developed in vivo silicon-based flexible large scale integrated circuits (LSI) for bio-medical wireless communication.
