Spintronic devices, a class of architectures that can store or transfer information by leveraging the intrinsic spin of electrons, have been found to be highly promising, both in terms of speed and efficiency. So far, however, ...
Even though lightning is a common phenomenon, the exact mechanism triggering a lightning discharge remains elusive. Scientists at the Dutch national research institute for mathematics CWI, the University of Groningen and ...

Electrons find each other repulsive. Nothing personal—it's just that their negative charges repel each other. So getting them to pair up and travel together, like they do in superconducting materials, requires a little ...

As part of an experiment to measure—to an extremely precise degree—the charge-to-mass ratios of protons and antiprotons, the RIKEN-led BASE collaboration at CERN, Geneva, Switzerland, has found that, within the uncertainty ...

The fast switching and modulation of light is at the heart, among other things, of modern data transfer, in which information is sent through fiber optic cables in the shape of modulated light beams. It has been possible ...

For most of us, a modern lifestyle without polymers is unthinkable… if only we knew what they were. The ordinary hardware-store terms we use for them include "plastics, polyethylene, epoxy resins, paints, adhesives, rubber"—without ...

In a photovoltaic cell, light generates opposite charges in the active layer. The charges must then be separated as quickly as possible to keep them from recombining. Positive charges are driven by a built-in electric field ...

Last year, MIT researchers discovered that when water droplets spontaneously jump away from superhydrophobic surfaces during condensation, they can gain electric charge in the process. Now, the same team has demonstrated ...

NASA's Parker Solar Probe (PSP) has flown close enough to the sun to detect the fine structure of the solar wind close to where it is generated at the sun's surface, revealing details that are lost as the wind exits the corona ...

"Supercapacitors" take the energy-storing abilities of capacitors (which store electrical charge that can be quickly dumped to power devices) a step further, storing a far greater charge in a much smaller package. In AIP ...
