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 ...

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 ...

When the free electrons absorb heat energy, they move much faster. As they move through the metal, free electrons crash into metal ions. This process is very much faster than conduction caused by ...
