“High-resolution imaging of radio emissions from an ultracool dwarf show a double-lobed structure like the radiation belts of Jupiter. Astronomers have described the first radiation belt observed outside our solar system, using a coordinated array of 39 radio dishes from …
“Physicists found that speeding electrons trapped in circular loops in graphene quantum dots are highly sensitive to external magnetic fields. Trapped electrons traveling in circular loops at extreme speeds inside graphene quantum dots are highly sensitive to external magnetic fields …
“Researchers used a scanning tunneling microscope to visualize quantum dots in bilayer graphene, an important step toward quantum information technologies Trapping and controlling electrons in bilayer graphene quantum dots yields a promising platform for quantum information technologies. Researchers at UC …
“Data storage devices and other emerging technologies use magnetic elements smaller than 100 nanometers, but studying their magnetization dynamics can be a challenge The performance of magnetic storage and memory devices depends on the magnetization dynamics of nanometer-scale magnetic elements …
“Advances in supercapacitor technology could lead to wider use of fast-charging energy storage devices and novel designs for electronic gadgets Scientists at UC Santa Cruz and Lawrence Livermore National Laboratory (LLNL) have reported unprecedented performance results for a supercapacitor electrode …
“Astronomers find close correlation between the mass of a galaxy’s central black hole and its star formation history Young galaxies blaze with bright new stars forming at a rapid rate, but star formation eventually shuts down as a galaxy …
“A new study by an international team of astronomers reveals that four Earth-sized planets orbit the nearest sun-like star, tau Ceti, which is about 12 light years away and visible to the naked eye. These planets have masses as low …
