Latest Electron Stories
Magnetic devices like hard drives, magnetic random access memories (MRAMs), molecular magnets, and quantum computers depend on the manipulation of magnetic properties.
Scientists seeking to understand the intricacies of high-temperature superconductivity—the ability of certain materials to carry electrical current with no energy loss—have been particularly puzzled by a mysterious phase that emerges as charge carriers are added that appears to compete with superconductivity.
Electromagnetic noise from AM broadcast signals (or "electrosmog") could be interfering with the migratory flight paths of birds by disrupting the animals' "internal compass,” German researchers reported this week in the journal Nature.
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory are seeking ways to synchronize the magnetic spins in nanoscale devices to build tiny yet more powerful signal-generating or receiving antennas and other electronics.
Junhao Lin, a Vanderbilt University Ph.D. student and visiting scientist at Oak Ridge National Laboratory (ORNL), has found a way to use a finely focused beam of electrons to create some of the smallest wires ever made.
When chemist Tehshik Yoon looks out his office window, he sees a source of energy to drive chemical reactions. Plants “learned” to synthesize chemicals with sunlight eons ago; Yoon came to the field a bit more recently.
In an attempt to help scale down the size of electronic devices to atomic dimensions, researchers from Cornell University and the Brookhaven National Laboratory have demonstrated how to convert a particular transition metal oxide from a metal to an insulator...
Late on April 1, the crown jewel of the Department of Energy's Thomas Jefferson National Accelerator Facility (“Jefferson Lab”) sparkled its way into a new era.
Scientists at MIT and Harvard University have developed a light lattice that traps atoms, a technique they say could aid in the creation of powerful quantum computing systems.
Drexel University researchers are turning some of the basic tenets of chemistry and physics upside down to cut a trail toward the discovery of a new set of materials.
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...
- In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
