Researchers Break Down Science Behind Plasmas
2012-02-15 13:48:07

[ Watch the Video ] Researchers have discovered clues to help give scientists a better understanding of how plasma jets from the sun occur. The team from the Division of Engineering and Applied Science at the California Institute of Technology (Caltech) used high-speed cameras to look at jets of plasma in the lab. During the experiments, they fired jets of hydrogen, nitrogen, and argon plasmas at speeds of about 6 to 30 miles per second across a distance of 8 inches in a vacuum....

A new study by food safety researchers at Drexel University demonstrates that plasma can be an effective method for killing pathogens on uncooked poultry. The proof-of-concept study was published in the January issue of the Journal of Food Protection. Although recent high-profile outbreaks of foodborne illness have involved contaminated fresh produce, the most common source of harmful bacteria in food is uncooked poultry and other meat products. The bacteria responsible for most foodborne...

Creating and observing super-hot solid plasma could lead to a greater understanding of fusion processes. In two separate studies, the world´s most powerful X-ray laser has been used to build the first atomic X-ray laser pulse, as well as to superheat and control a clump of 2-million-degree matter. The atomic laser could be used to watch biological molecules at work, while the creation of hot dense matter could be used to understand the processes of nuclear fusion. Scientists...

Previous theories imposed a limit on how 'liquid' fluids can be -- but new calculations show that quark-gluon-plasma in high-energy particle accelerators can be even have a lower viscosity than this limit suggests How liquid can a fluid be? This is a question particle physicists at the Vienna University of Technology have been working on. The "most perfect liquid" is nothing like water, but the extremely hot quark-gluon-plasma which is produced in heavy-ion collisions at the Large Hadron...

Engineers have discovered details about the behavior of ultrafast laser pulses that may lead to new applications in manufacturing, diagnostics and other research. Ultrafast laser pulses are used to create features and surface textures in metals, ceramics and other materials for applications including the manufacture of solar cells and biosensors. The lasers pulse at durations of 100 femtoseconds, or quadrillionths of a second, and cause electrons to reach temperatures greater than 60,000...

Solar storms and associated Coronal Mass Ejections (CMEs) can significantly erode the lunar surface according to a new set of computer simulations by NASA scientists. In addition to removing a surprisingly large amount of material from the lunar surface, this could be a major method of atmospheric loss for planets like Mars that are unprotected by a global magnetic field. The research is being led by Rosemary Killen at NASA's Goddard Space Flight Center, Greenbelt, Md., as part of the...

Inhaling streams of electrically charged gas known as cold plasma could help cure the common cold, researchers from the Max Planck Institute for Extraterrestrial Physics in Germany are claiming. According to a December 4 report by the Deccan Chronicle, an English-language publication in India, the scientists say that they have discovered that a stream of the ionized gas "deactivates" virus, including those that cause colds. In fact, when those viruses were exposed to cold plasma for...

Negative ions play an important role in everything from how our bodies function to the structure of the universe. Scientists from the University of Gothenburg, Sweden, have now developed a new method that makes it possible to study how the electrons in negative ions interact in, which is important in, for example, superconductors and in radiocarbon dating. "By studying atoms with a negative charge, 'negative ions', we can learn how electrons coordinate their motion in what can be compared...

Hannes Olof Gösta Alfvén (May 30, 1908 - April 2, 1995) was a Swedish plasma physicist born in Norrköping, Sweden. Alfvén received his PhD from the University of Uppsala in 1934. His thesis was titled "Investigations of the Ultra-short Electromagnetic Waves." He was originally trained as an electrical power engineer and later moved on to research and teaching in the fields of plasma physics. Alfvén made many contributions to plasma physics, including theories describing the...

Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...

Solar Prominence -- Solar prominences are large arch-shaped structures observable in the solar corona. These often have a twist and occasionally become unstable, ejecting plasma and magnetic flux out from the sun. The physics of solar prominence instability is believed to be governed by magnetic forces and magnetic helicity issues. It is thought that instability occurs when a magnetic flux tube becomes excessively twisted. ----- Click here to learn more on this topic from eLibrary:
