2-proton Bit Controlled By Single Copper Atom
2014-01-17 12:27:57

Institute of Physical Chemistry of the Polish Academy of Sciences Just a single foreign atom located in the vicinity of a molecule can change spatial arrangement of its atoms. In a spectacular experiment, an international team of researchers was able to change persistently positions of the nuclei of hydrogen atoms in a porphycene molecule by approaching a single copper atom to the molecule. A subatomic bit formed by two protons tunneling inside a simple organic molecule can be switched...

Novel biological mechanism relays electrons in proteins in mineral-breathing bacteria important for energy-related research Researchers simulating how certain bacteria run electrical current through tiny molecular wires have discovered a secret Nature uses for electron travel. The results are key to understanding how the bacteria do chemistry in the ground, and will help researchers use them in microbial fuel cells, batteries, or for turning waste into electricity. Within the bacteria's...

The UPV/EHU physicist Eneko Malatsetxebarria has explored, on a theoretical level, some quantum effects that take place in atoms at a very low temperature. Firstly, he has discovered that boson-type atoms and fermion-type ones can be mixed in a specific way. So he has made the necessary conditions for carrying out these experiments available to experimental physicists. Secondly, he has deduced how fermions would influence bosons in this case. The experiments carried out on cold atoms are...

April Flowers for redOrbit.com - Your Universe Online Data from NASA's Van Allen Probes mission has helped researchers resolve decades of scientific uncertainty over the origin of ultra-relativistic electrons in Earth's near space environment. The findings, published in Nature, are likely to influence our understanding of planetary magnetospheres throughout the universe. One of the primary science objectives of the Van Allen Probes is to understand the processes that control the...

This work was recently published in Physical Review Letters In contrast to its apparent simplicity (that brought Einstein his Nobel Prize), the photoelectric effect, when an electron is knocked out from its parent atom by a photon, is quite complicated to analyze in general, especially when the atom contains a large number of electrons. Like the many-body problem in classical mechanics, the quantum many-body problem is very difficult to conceptualize and remains a serious challenge for...

Decades-old Mystery In Earth's Upper Atmosphere Solved
2013-12-18 14:51:49

University of California - Los Angeles New research published in the journal Nature resolves decades of scientific controversy over the origin of the extremely energetic particles known as ultra-relativistic electrons in the Earth's near-space environment and is likely to influence our understanding of planetary magnetospheres throughout the universe. Discovering the processes that control the formation and ultimate loss of these electrons in the Van Allen radiation belts — the rings...

Researchers Observe High Energy Losses In Vicinity Of Charge Density Waves
2013-12-16 07:29:11

University of Basel In collaboration with the University of Basel, an international team of researchers has observed a strong energy loss caused by frictional effects in the vicinity of charge density waves. This may have practical significance in the control of nanoscale friction. The results have been published in the scientific journal Nature Materials. Friction is often seen as an adverse phenomenon that leads to wear and causes energy loss. Conversely, however, too little friction...

Harvesting Wasted Power Using TriboElectrification
2013-12-12 12:54:03

[ Watch the video: Harvesting the World's Mechanical Energy ] Brett Smith for redOrbit.com - Your Universe Online From ocean waves to the action of walking across a floor, energy is all around us. Now, a materials scientist from Georgia Tech has developed a system to capture that “wasted energy” and convert it into electricity. By using a phenomenon known as the triboelectric effect, a team led by Zhong Lin Wang has been able to create significant amounts of electric power by...

Ultrashort laser pulses reveal that 'coherence' plays a subtle role in energy transfers Sophisticated recent experiments with ultrashort laser pulses support the idea that intuition-defying quantum interactions between molecules help plants, algae, and some bacteria efficiently gather light to fuel their growth. But key details of nature's vital light-harvesting mechanisms remain obscure, and the exact role that quantum physics may play in understanding them is more subtle than was once...

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...

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...
