Achieving high-energy density remains a key objective for advanced energy storage systems. However, challenges, such as poor cathode conductivity, anode dendrite formation, polysulfide shuttling, and ...

An emitter near a surface induces an image dipole that can modify the observed emission intensity and radiation pattern. These image-dipole effects are generally not taken into account in ...

As global demand for sustainable energy surges, the performance ceiling of current battery technologies is increasingly tied to how efficiently ions ...

The Milky Way galaxy is currently racing through space at about 2 million km/h (1.2 million mph), on a journey towards a gravitational anomaly known as the Great Attractor, which is in turn being ...

In this video, we derive the far-field electric field of a dipole in the perpendicular direction, explaining each step and the physical meaning behind the math. This breakdown helps clarify how dipole ...

Incompatible moments A spinning charge (left) acts like a loop of current to produce a magnetic dipole moment (blue arrow). Distorting the electron's charge distribution (middle) produces an electric ...

Physicists are closer to finding out if the electron is a point charge or whether it has an internal distribution of charge known as an electric dipole moment. For the first time, Ed Hinds and ...

The shape of the universe is not something we often think about.

Do electrons have a fourth property in addition to mass, charge and spin, as popular physics theories such as supersymmetry predict? Researchers from Germany, the Czech Republic and the United States ...

A dipole antenna is easy, right? Two wires, each a quarter wavelength long, emanate from a coax or other feedline. Unless it is an off-center dipole. The length is still the same, but you move the ...
