For the first time, physicists at the University of Basel have succeeded in measuring the magnetic properties of atomically thin van der Waals materials on the nanoscale. They used diamond quantum sensors to determine the strength of the magnetization of individual atomic layers of the material chromium triiodide. In addition, they found a long-sought explanation for the unusual magnetic properties of the material. The journal Science has published the findings.
Researchers at TU Graz have discovered a means of suppressing singlet oxygen formation in lithium-oxygen batteries in order to extend their useful lives.
In conventional organic solar cells, the electrons exhibit their particle-nature and need to jump between organic molecules in the cell. The conductivity is, therefore, lower than that of crystalline silicon solar cells. Researchers have succeeded to arrange the organic molecules in highly ordered manner like in crystals and to invoke the wave-nature. 'Conductive bands' are formed by energy dispersive states and contribute to the high-carrier conductivity. It may improve the total efficiency of the cell.
The human eye is particularly sensitive to green, but less sensitive to blue and red. Chemists led by Hubert Huppertz at the University of Innsbruck have now developed a new red phosphor whose light is well perceived by the eye. This increases the light yield of white LEDs by around one-sixth, which can significantly improve the energy efficiency of lighting systems.
Superinjection, the effect used in lasers and LEDs creation can work in 'pure' semiconductors, which was previously considered impossible. This opens up new prospects for designing highly efficient blue, violet, ultraviolet, and white LEDs, as well as light sources for optical wireless communication (Li-Fi), new types of lasers, transmitters for the quantum internet, and optical devices for early disease diagnostics.
New research shows how Cooper pairs -- quasiparticles that make superconductivity possible -- can also play an opposite role in an exotic type of insulating materials known as Cooper pair insulators.
The quantum theory group at the University of Sydney is behind two papers published this month in Nature publications that are pushing the boundaries of quantum computing.
Drexel University researchers have developed a conductive ink made from a special type of material they discovered, called MXene, that was used by the Trinity College researchers to print components for electronic devices. The ink is additive-free, which means it can print the finished devices in one step without any special finishing treatments.
U.S. Naval Research Laboratory (NRL) discovers new method to passivate defects in next generation optical materials.
Researchers from Tokyo Metropolitan University have found that crystals of a recently discovered superconducting material, a layered bismuth chalcogenide with a four-fold symmetric structure, shows only two-fold symmetry in its superconductivity. The origin of superconductivity in these structures is not yet well understood; this finding suggests a connection with an enigmatic class of materials known as nematic superconductors and the extraordinary mechanisms by which superconductivity can emerge at easier-to-reach temperatures.
