The use of acoustic inversion to estimate the bubble size distribution in pipelines
New research from the University of Southampton has devised a new method to more accurately measure gas bubbles in pipelines
Watching an electron being born
Atomic processes take place on extremely short time scales. Measurements at the Vienna University of Technology (TU Vienna) can now visualize these processes
BaBar data preserved in ‘computational cocoon’ for future analysis
More than eight years worth of pristine particle physics data will remain available for analysis or re-analysis at least until 2018, now that BaBar’s Long Term Data Access project is complete. The project preserves a complete set of BaBar data – all 530-plus inverse femtobarns of it – by, in a sense, stopping time for it, embedding it in a computational cocoon safe from upgrades, bug fixes and patches
Beyond the high-speed hard drive: Topological insulators open a path to room-temperature spintronics
(Phys.org) — Strange new materials experimentally identified just a few years ago are now driving research in condensed-matter physics around the world. First theorized and then discovered by researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) and their colleagues in other institutions, these “strong 3-D topological insulators” – TIs for short – are seemingly mundane semiconductors with startling properties. For starters, picture a good insulator on the inside that’s a good conductor on its surface – something like a copper-coated bowling ball
Research opens doors to UV disinfection using LED technology
Research from North Carolina State University will allow the development of energy-efficient LED devices that use ultraviolet (UV) light to kill pathogens such as bacteria and viruses. The technology has a wide array of applications ranging from drinking-water treatment to sterilizing surgical tools
Spin polarized supercurrents optimized with a simple flip
(Phys.org) — Researchers from Michigan State University, the NIST Center for Neutron Research, and the NIST Center for Nanoscale Science and Technology have discovered the key to controlling and enhancing the lossless flow of a current with a single electron spin state in a standard superconducting device
The new world of gamma-ray optics
Scientists discover that certain materials like silicon or gold exhibit a surprisingly large refractive index for extremely high energetic gamma-rays
A physicist and an inventor
As a boy growing up in Croatia, Marin Soljacic wanted to be an inventor. But he wasn’t interested only in designing new products; he wanted to discover physical phenomena that would enable completely new technologies
Chinese group breaks distance record for teleporting qubits
(Phys.org) — A team of Chinese physicists has broken the distance record for teleporting qubits, extending it from 16 to 97 kilometers. They did so, as they explain in their paper uploaded to the preprint server arXiv, using the phenomenon known as entanglement
