The field of metamaterials involves augmenting materials with specially designed patterns, enabling those materials to manipulate electromagnetic waves and fields in previously impossible ways. Now, researchers from the University of Pennsylvania have come up with a theory for moving this phenomenon onto the quantum scale, laying out blueprints for materials where electrons have nearly zero effective mass.
Researchers have introduced a novel material for electrodes based on affordable melamine foam and carbon black. The high porosity significantly facilitates fast mass transport and a high number of catalytically active centers drastically increase the oxygen-reducing activity of cathodes for fuel cells and metal-air batteries.
Researchers from the Institute of Photonic Sciences (ICFO) have shown that groups of photons organized in certain quantum states can gently explore the properties of objects in a non-invasive way. The results overcome for the first time a limit imposed by quantum mechanics, and may permit the observation of unknown properties of ultra-sensitive objects such as individual atoms or living cells.
Two Leibniz institutes broke new technological ground and successfully combined their - up to now separate - technology worlds. Due to their high performance the novel chips developed within the HiTeK project shall open up new applications.
University of Illinois researchers developed mats of metal oxide nanofibers that scrub sulfur from petroleum-based fuels much more effectively than traditional materials. Such efficiency could lower costs and improve performance for fuel-based catalysis, advanced energy applications and toxic gas removal.
Snow is the be-all and end-all for alpine ski resorts. Now a tiny sensor has been developed to determine how much cold gold there is on the slopes and how much more should be produced. The sensor is based on Norwegian radar technology and is no larger than a match head.
This new nanotechnology could be used for cancer diagnosis and give insight into the mechanisms of how cancer spreads throughout the body. The device provides a convenient and non-invasive alternative to biopsy, the current method for diagnosis of metastatic cancer.
One milligram per hour: fluid flow can be measured with great precision using a tiny 'wobbling' tube with a diameter of only 40 micrometres. Thanks to a new technique, the sensor, which makes use of the 'Coriolis effect', can be made even more compact.
