We are surrounded by electronic devices. Transistors are used to power telephones, computers, televisions, hi-fi systems and game consoles as well as cars, airplanes and the like. Today’s silicon-based electronics, however, consume a substantial and ever-increasing share of the world’s energy. A number of researchers are exploring the properties of materials that are more complex than silicon but that show promise for the electronic devices of tomorrow – and that are less electricity-hungry. In keeping with this approach, scientists from…
For the first time ever, scientists have witnessed the interaction of a new phase of matter known as “time crystals”. The discovery, published in Nature Materials, may lead to applications in quantum information processing because time crystals automatically remain intact – coherent – in varying conditions. Protecting coherence is the main difficulty hindering the development of powerful quantum computers. Dr Samuli Autti, lead author from Lancaster University, said: “Controlling the interaction of two time crystals is a major achievement. Before…
A team of international physicists led by Lia Krusin-Elbaum of the City College of New York, has created a new topological magnetic superlattice material, that at a high temperature can conduct electrical current without dissipation and lost energy. The finding, detailed in a paper published in Nature Physics, could be the basis of research leading to an entire new quantum materials class that can potentially provide a platform for error-free quantum computing. The material in the form of crystals is…
Applied to skin as a piece of sticking plaster, the device developed by Brazilian researchers can be used to monitor human metabolism and administer drugs A wearable sensor printed on microbial nanocellulose, a natural polymer, has been created in Brazil by researchers at the University of São Paulo (USP) in São Carlos in collaboration with colleagues at São Paulo State University (UNESP) in Araraquara, the University of Araraquara (UNIARA), the University of Campinas (UNICAMP), and the Brazilian National Nanotechnology Laboratory…
Spun by spiders and silkworms, silk has mystified human engineers who have yet to figure out how to artificially recreate this tough, fine fiber. But by combining silk, which is safe for use in the human body, with synthetic compounds, one research team is getting closer to developing new implantable composite materials with the best properties of both. Potential applications, which are still years away, could include structures that hold bone in place after surgery or replacements for the cartilage…
Fraunhofer IWS applies innovative laser melting system for complex copper components for the first time Creating sophisticatedly shaped plastic parts with the 3D printer is no longer an art process, but an everyday technology. This is quite different with pure copper: Until now, it has not been possible to completely melt the metal to create complex components layer by layer using infrared lasers. As a result, the Fraunhofer Institute for Material and Beam Technology IWS in Dresden is now using…
Within the Framework of a research project on the chemical imaging analysis of plastic digestion in caterpillars (RauPE), a team from Fraunhofer LBF used…
Oliver Hofmann and his research group at the Institute of Solid State Physics at TU Graz are working on the optimization of modern electronics. A key role in…
Atoms that make up humans and trees and kitchen tables generally bond together by sharing electrons – think of electrons as the atomic glue of life. Nagoya…
