Latest Electron Stories
Whether it is diagnostic imaging, analysis of unknown substances or ultrafast communication – terahertz radiation sources are becoming more and more important. At the Vienna University of Technology, an important breakthrough has been achieved.
MIT physicists have proposed a new experiment to look for the elusive dark matter particle known as the 'A Prime' particle.
Imagine you order a delivery of several glass vases in different colors. Each vase is sent as a separate parcel. What would you think of the courier if the parcels arrive apparently undamaged, yet when you open them, it turns out that all the red vases are intact and all the green ones are smashed to pieces?
Every day, all day, our DNA gets beaten up by chemicals and radiation -- but remarkably, most of us stay healthy. Now, an investigation by a team of French and Canadian researchers has produced insights into a little-studied but common radiation threat to DNA: low-energy electrons (LEEs), with energies of 0-15 electron volts.
This video and article explain how sudden exercise releases free radicals (loose electrons) in the body and how those electrons damage organs, tissues and can cause death.
Topology -- the understanding of how things are connected -- remains abstract, even with the popular example of doughnuts and coffee cups.
Scientists introduce a general theoretical approach that describes all known forms of high-temperature superconductivity and their "intertwined" phases
Imagine if the "information superhighway" had HOV lanes so that data could be stored, processed and disseminated many times faster than possible with today's electronics.
Disney researchers in Pittsburgh have discovered a way to store energy in paper-like materials that can later be harvested via rubbing, sliding or tapping. The resulting energy can then be used to turn on LED lights, activate an e-ink display, or turn on other low-power devices.
In celebration of the publication’s 25th anniversary, Physics World has selected the five most important physics-related discoveries of the past quarter-century, as well as five recent breakthroughs with the potential to change the world.
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...
