Researchers Develop 'Spinning Trap' To Measure Electron Roundness
2013-12-05 19:47:47

National Institute of Standards and Technology (NIST) JILA researchers have developed a method of spinning electric and magnetic fields around trapped molecular ions to measure whether the ions' tiny electrons are truly round—research with major implications for future scientific understanding of the universe. As described in the Dec. 6, 2013, issue of Science, the JILA team used their new spinning method to make their first measurement of the electron's roundness—technically, the...

Wormholes Driving Quantum Entanglement
2013-12-04 15:25:47

John P. Millis, PhD for redOrbit.com - Your Universe Online One of the strangest consequences of quantum theory, is what happens when elementary particles are created in pairs. These individual charges become entangled with their counterparts. The result is that interactions with one of these particles creates direct consequences for the other, even if the other particle is on the other side of the Universe. The simplest example of this is when an electron and positron are created when...

Decay Used To Create Quantum Information
2013-11-25 09:47:26

University of Copenhagen - Niels Bohr Institute Usually, when researchers work with quantum information, they do everything they can to prevent the information from decaying. Now researchers at the Niels Bohr Institute, among others, have flipped things around and are exploiting the decay to create the so-called entanglement of atomic systems, which is the foundation for quantum information processing. The results are published in the scientific journal, Nature. "When working with...

Research Quality X-rays Could Have Widespread Applications
2013-11-25 08:27:00

University of Nebraska-Lincoln Using a compact but powerful laser, a research team at the University of Nebraska-Lincoln has developed a new way to generate synchrotron X-rays. Although the high quality of synchrotron X-rays make them ideal for research ranging from the structure of matter to advanced medical images, access to the technology has been limited until now. Most traditional synchrotron X-ray devices are gigantic and costly, available only at a few sites around the world....

X-rays Reveal Another Feature Of High-temperature Superconductivity
2013-11-25 08:20:57

European Synchrotron Radiation Facility Discovery of a giant resonance puts these materials further apart Classical and high-temperature superconductors differ hugely in the value of the critical temperatures at which they lose all electrical resistance. Scientists have now used powerful X-rays to establish another big difference: high-temperature superconductivity cannot be accounted for by the mechanism that leads to conventional superconductivity. As this mechanism called...

Exploiting Flaws In Diamond Fragments Paves Way For Nanoscale MRI
2013-11-25 08:02:31

University of Cambridge By exploiting flaws in miniscule diamond fragments, researchers say they have achieved enough coherence of the magnetic moment inherent in these defects to harness their potential for precise quantum sensors in a material that is 'biocompatible'. Nanoscopic thermal and magnetic field detectors - which can be inserted into living cells - could enhance our understanding of everything from chemical reactions within single cells to signalling in neural networks and...

2-D Tin Could Be The Next Super Material

SLAC National Accelerator Laboratory Theorists Predict New Single-Layer Material Could Go Beyond Graphene, Conducting Electricity with 100 Percent Efficiency at Room Temperature A single layer of tin atoms could be the world’s first material to conduct electricity with 100 percent efficiency at the temperatures that computer chips operate, according to a team of theoretical physicists led by researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory...

Study Could Lead To Paradigm Shift In Organic Solar Cell Research
2013-11-20 09:56:25

Stanford University Organic solar cells have long been touted as lightweight, low-cost alternatives to rigid solar panels made of silicon. Dramatic improvements in the efficiency of organic photovoltaics have been made in recent years, yet the fundamental question of how these devices convert sunlight into electricity is still hotly debated. Now a Stanford University research team is weighing in on the controversy. Their findings, published in the Nov. 17 issue of the journal Nature...

Advances in technology for computation and information storage always require to make the systems smaller and faster. The limits of miniaturization are those set by nature: Materials are composed by specific units, the atoms, that cannot be further divided. The question arising is: Can we still codify information at the atomic scale? And the answer is yes, we can! but one needs to manipulate a property of the atoms, individually, and keep them in that state there for sufficiently long time to...

Single-atom Bit Forms Smallest Memory In The World
2013-11-18 12:09:44

Karlsruhe Institute of Technology Control of the Magnetic Moment of Single Atoms Is the Key to Compact Data Memories and Quantum Computers One atom equals one bit: According to this design principle, we would like to construct magnetic data memories in the future. Presently, a compound of several million atoms is needed to stabilize a magnetic bit in a way that hard disk data are secure for several years. However, researchers from KIT have just made a big step towards a single-atom...

The Cathode Ray Tube, which has internal or external means to accelerate and deflect electron beams, is a vacuum tube containing an electron gun and a fluorescent screen. The electron beams that are deflected are used to create images in the form of light emitted from the fluorescent screen. The CRT works by using an evacuated glass envelope which is large, deep, heavy, and relatively fragile. Ferdinand Braun is credited with the first CRT in 1897. It can also be known as the Braun tube....

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...

  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
