New Technique Could Reveal High Detail Of Earth's Composition
2013-02-22 10:50:16

April Flowers for redOrbit.com - Your Universe Online In a new study recently published in the journal Science, a research team from Amherst College and The University of Texas at Austin has described a new technique that might one day reveal the composition and characteristics of the deep Earth in never before seen detail. There's just a tiny little hitch in the new technique. It relies on a fifth force of nature that has not yet been detected. Current physics theories hold that there...

For purposes of their research, the scientists irradiated two separate layered systems with ultrashort laser pulses on the order of just one hundred femtoseconds (10-15 s). One sample consisted essentially of a single thin layer of ferromagnetic nickel. By contrast, a second sample of this same nickel material was coated with a non-magnetic layer of gold. Only a mere 30 nanometers (10-9 m) thick, the gold layer swallowed up the lion's share of the laser light so that barely any light ended up...

Charged particle accelerators have become crucially important to modern day life, be it in health care for cancer treatment or for answering important fundamental scientific questions like the existence of the HIGGS boson, the so called 'God particle'. In a simple picture, charged particles like electrons and protons are accelerated between two end plates across which an electrical voltage is applied. High energies need high voltages (millions and billions of volts) and long acceleration...

Proton May Have Lost Weight
2013-01-25 08:27:16

April Flowers for redOrbit.com - Your Universe Online A new study, released this week in the journal Science, shows that even in the world of sub-atomic particles, size matters. An international group of scientists led by Aldo Antognini, a physicist at the Max Planck Institute for Quantum Optics, say the proton, a basic building block of all matter, appears to be smaller than previously thought. This finding, which confirms a similar result the team showed in 2010, may open new...

Chemical Processes Controlled With Ultra-short Laser Pulses

Technische Universität Wien How can molecules be split in a controlled manner? A new experiment at the TU Vienna shows how research into ultra-short laser pulses can be combined with chemistry. Chemical reactions occur so quickly that it is completely impossible to observe their progress or to control them using conventional methods. However, new developments in electrical engineering and quantum technology enable us to achieve a more exact understanding and improved...

Electron Beams That Possess An Inner Rotation Created
2012-11-05 13:28:11

Vienna University of Technology Vortex beams, rotating like a tornado, offer completely new possibilities for electron microscopy. A method of producing extremely intense vortex beams has been discovered at the Vienna University of Technology (TU Vienna). Nowadays, electron microscopes are an essential tool, especially in the field of materials science. At TU Vienna, electron beams are being created that possess an inner rotation, similarly to a tornado. These "vortex beams" cannot only...

Studies by Berkeley Lab scientists of electron beam quality in laser plasma accelerators include novel tests for slice-energy spread Part Two: Slicing through the electron beam Wim Leemans of Berkeley Lab´s Accelerator and Fusion Research Division heads LOASIS, the Laser and Optical Accelerator Systems Integrated Studies, an oasis indeed for students pursuing graduate studies in laser plasma acceleration (LPA). Among the most promising applications of future table-top accelerators...

Cosmic Rays Help Diagnose Nuclear Reactors
2012-10-18 13:50:41

Brett Smith for redOrbit.com - Your Universe Online They may not be using alien technology, but physicists from Los Alamos National Laboratory are looking to outer space for help in diagnosing a damaged nuclear reactors like the one that caused massive evacuations around the Fukushima Daiichi plant in March 2011. According to their report in the journal Physical Letters, the research team from Los Alamos National Laboratory has found a way to use cosmic ray radiation to...

3D Electrons Viewed At High Speed
2012-09-18 13:57:25

Lee Rannals for redOrbit.com - Your Universe Online A team of researchers at MIT are trying to unlock the mysteries of a promising material for future electronic devices. Scientists have managed to create three-dimensional "movies" of electron behavior in a topological insulator (TI), which were first discovered a few years ago. TIs are considered to hold great promise for new kinds of electronic devices, and having a better understanding of the unusual behavior within the material...

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...
