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...

How to improve the performance of the plasma actuators is a problem that is of great interest to many scientific researchers in the field of electrohydrodynamics. Professor WANG Lianze and his group from the School of Aerospace, Tsinghua University, set out to investigate this problem. They developed novel plasma actuators using various winding-shaped electrodes to create plasma actuators which induce three-dimensional variations in the shear layer, offering significant flexibility in flow...

New Light Cast On Electrons Heated To Several Billion Degrees

A new class of high power lasers can effectively accelerate particles like electrons and ions with very intense, short laser pulses.  This has attracted the interest of researchers around the globe, working out the details of the acceleration process which occurs when a laser beam impinges on a thin foil to accelerate ions from the foil´s rear surface to high energies.  The electrons in the foil are heated by the laser pulse, thereby gaining energy.  These electrons in...

A revolutionary approach to illumination It was not too long ago that basic science lectures began with the three forms of matter: gases, liquids and solids–and somewhere along the line plasmas were occasionally added to the list. But to be precise, a plasma is an ionized gas; thus, a subset of the big three. But this subset has coexisted with the other forms since the Big Bang and actually makes up 99 percent of the universe. It is found in our Sun and all the other stars, and in...

Image 1 - Cluster Reveals Earth's Bow Shock Is Remarkably Thin
2011-11-17 05:07:47

A new study based on data from ESA's Cluster mission has revealed that the bow shock formed by the solar wind as it encounters Earth's magnetic field is remarkably thin: it measures only 17 kilometers across. Thin astrophysical shocks such as this are candidate sites for early phases of particle acceleration. The finding thus sheds new light on the much debated issue of particle injection in the context of cosmic ray acceleration. Most baryonic matter in the Universe consists of charged...

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:
