The prospect of a nanoscale light source emitting at a wavelength that can be tuned by the user is enticing for researchers working in many areas of nanoscience and technology, including the ...

Measuring shot noise without external influences is not easy. In a metal, the vibration of the atoms’ lattice can push ...

Light could now travel freely in the universe because it was no longer blocked by the free electrons. This means that the ...

Free radicals are unstable atoms or molecules with free outer electrons. This makes them highly reactive because free electrons always strive to form a stable bond. This stabilization involves gaining ...

At high enough flight velocities, the intense heating of the gas generates a plasma layer around the vehicle. The presence of free electrons in the flow field has been known to hinder the transmission ...

Metals have lots of electrons, and some of them are free to move through the metal, so when they’re connected in a circuit, the electrons can easily flow. This flow of electric charge is called ...
