Space Twisters Key To Solar Atmosphere's Heat

Lawrence LeBlond for redOrbit.com - Your Universe Online An international team of researchers have discovered enormous tornadoes in space, more than a thousand miles wide, that could quite possibly be heating the surface of the Sun to more than a million degrees centigrade, a finding that has possible implications for clean Earth energy. These super tornadoes -- which are thousands of times larger and immensely more powerful than anything seen on Earth -- twist at speeds beyond 6,000...

Gallium nitride (GaN) is a highly promising material for a wide range of optical and high-power electronic devices, which can be fabricated by dry etching with plasmas. However, the plasma-induced defects and surface residues that remain after such processes tend to degrade the optical and electrical properties of the devices. A team of Japanese researchers has developed and tested a new way to "heal" such defects. The team exposed plasma-damaged GaN to hydrogen (H) radicals at room...

Enceladus Plume Highlights 'Dusty Plasma'
2012-06-04 07:20:05

Recent findings from NASA's Cassini mission reveal that Saturn's geyser moon Enceladus provides a special laboratory for watching unusual behavior of plasma, or hot ionized gas. In these recent findings, some Cassini scientists think they have observed "dusty plasma," a condition theorized but not previously observed on site, near Enceladus. Data from Cassini's fields and particles instruments also show that the usual "heavy" and "light" species of charged particles in normal plasma are...

For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds (a femtosecond is one quadrillionth of a second). Using the Linac Coherent Light Source (LCLS) X-ray Free-Electron Laser (XFEL) at SLAC National Accelerator Laboratory at Stanford, Stefan Hau-Riege of Lawrence Livermore National Laboratory and colleagues heated graphite to induce a transition from solid to liquid and to warm-dense plasma. Ultrafast phase...

There are some simple plasma cutter tips that can help you understand the technology and acquaint yourself with its use. The perfectly installed arc plasma cutting setup can be safer than the oxyfuel cutting system as there is a chance of flashbacks or even risk of combustible gases through exposed hoses when using oxy fuel torches. Plasma cutter is therefore easier for jobs like hole - piecing as it uses plasma jets. Hayward, CA (PRWEB) May 05, 2012 The plasma arc and welding process has...

Whilst some bacteria can provide health benefits there are others that can do annoying things — like kill you. So in order to save ourselves we should probably kill them first. So, stand aside bacterial wipes, hand sanitizers and antiseptic sprays there is a new bug zapper in town. Bring in the plasma flashlight — a torch that emits a plasma jet that kills bacteria on the skin in an instant. Developed by a group of Chinese and Australian scientists, including CSIRO, the...

A group of Chinese and Australian scientists have developed a handheld, battery-powered plasma-producing device that can rid skin of bacteria in an instant. The device could be used in ambulance emergency calls, natural disaster sites, military combat operations and many other instances where treatment is required in remote locations. The plasma flashlight, presented today, 5 April, in IOP Publishing's Journal of Physics D: Applied Physics is driven by a 12 V battery and doesn't require...

New physical attraction between ions in quantum plasmas Nowadays, ever smaller and more powerful computer chips are in demand. RUB physicists have discovered a new physical attraction that accelerates this progress. Prof. Dr. Padma Kant Shukla and Dr. Bengt Eliasson found a previously unknown phenomenon in quantum plasmas. A negatively charged potential makes it possible to combine positively charged particles (ions) in atom-like structures within the plasma. In this way, current can be...

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:

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
