A team of Hokkaido University researchers has developed a novel material synthesis method called proton-driven ion introduction (PDII) which utilizes a phenomenon similar to 'ion billiards.' The new method could pave the way for creating numerous new materials, thus drastically advancing materials sciences.
There are too many high-energy positrons in the cosmic rays reaching the Earth. These positrons (particles that are antimatter equivalents of electrons) could be being produced by pulsars in our vicinity. The most recent measurements from the HAWC Observatory in Mexico have practically excluded this possibility, strengthening the competing and much more exotic hypothesis concerning the origin of the excess positrons.
For the first time, physicists at MIT and Princeton University have developed a technique to visualize the behavior of electrons beneath a material's surface.
Results disprove existence of a type of light axion.
Fusion is the process that powers the sun, harnessing it on Earth would provide unlimited clean energy. Researchers say that constructing a fusion power plant has proven to be a daunting task because there have been no materials that could survive the grueling conditions found in the core of a fusion reactor. Now, researchers at Texas A&M University have discovered a way to make materials that may be suitable for use in future fusion reactors.
Physicists at Aalto University have made a breakthrough in revising methods largely discarded 15 years ago. They have discovered a microscopic mechanism that will allow gallium nitride semiconductors to be used in electronic devices that distribute large amounts of electric power.
Polymer nanoagents that can 'light up' tiny areas of diseased tissues that conventional methods fail to detect, have been created by a research team led by Nanyang Technological University, Singapore.
Physicists at NIST have come up with a way to link a group of atoms' quantum mechanical properties among themselves far more quickly than is currently possible, potentially providing a tool for highly precise sensing and quantum computer applications. NIST has applied for a patent on the method, which is detailed in a new paper in Physical Review Letters.
Matter in the cores of old white dwarfs and the crusts of neutron stars is compressed to unimaginable densities by intense gravitational forces. The scientific community believes this matter is composed of Coulomb crystals that form at temperatures potentially as high as 100 million Kelvin. Researchers in Russia clarify the physics of these crystals this week in the journal Physics of Plasmas.
There's been an unsolved mystery associated with mixed valence compounds: When the valence state of an element in these compounds changes with increased temperature, the number of electrons associated with that element decreases, as well. But just where do those electrons go? Using a combination of state-of-the-art tools, including X-ray measurements at the Cornell High Energy Synchrotron Source (CHESS), Cornell researchers have come up with the answer.
