Scientists have uncovered the exact mechanism that causes new solar cells to break down, and suggest a potential solution.
Greater understanding of reflectionless, highly refractive index metasurfaces is critical to developing wireless technology beyond 5G and manipulating THz waves for a host of yet-undiscovered commercial applications.
In most cameras, there is a trade-off between the field-of-view and resolution. Omnidirectional cameras offer a 360-degree field of view but poor resolution. In a new study, researchers from Shibaura Institute of Technology, Japan design a dual camera-based platform employing an omnidirectional camera for target detection and a separate camera for its high-resolution capture and report an overall improved performance, opening doors to potential applications in security systems.
New experiments conducted at Princeton University provide evidence for a decades-old theory that, in the quantum regime, an electron behaves as if it is made of two particles: one particle that carries its negative charge and the other that gives it a magnet-like property called spin. The team detected evidence for this theory in materials called quantum spin liquids.
Tie Jun Cui, professor at Southeast University's Institute of Electromagnetic Space, remarks, "Glide symmetry offers powerful and flexible control of SSPPs and may bring about new solutions in future integrated circuits." Cui envisions that when serious line-to-line interference damages the performance of circuits, an alternating arrangement of glide and nonglide symmetric TLs can restore and guarantee signal accuracy.
A team of physicists and chemists has developed a highly sensitive sensor, which was made possible by a new heterostructure consisting of atomically precise graphene nanoribbons / Publication in 'Nature Communications'
An enzyme could make a dream come true for the energy industry: It can efficiently produce hydrogen using electricity and can also generate electricity from hydrogen. The enzyme is protected by embedding it in a polymer. An international research team with significant participation of scientists from Technical University of Munich (TUM) has presented the system in the renowned science journal Nature Catalysis.
Researchers have made what is believed to be the smallest state-of-the-art RFID chip, which should drive down the cost of RFID tags. In addition, the chip's design makes it possible to embed RFID tags into high value chips, such as computer chips, boosting supply chain security for high-end technologies.
Researchers from the National University of Singapore have created a new class of intelligent materials. It has the structure of a two-dimensional (2D) material, but behaves like an electrolyte - and could be a new way to deliver drugs within the body.
Lancaster University scientists have demonstrated that other physicists' recent "discovery" of the field effect in superconductors is nothing but hot electrons after all. A team of scientists in the Lancaster Physics Department have found new and compelling evidence that the observation of the field effect in superconducting metals by another group can be explained by a simple mechanism involving the injection of the electrons, without the need for novel physics.
