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 ...

In a new experiment, light beams carrying orbital angular momentum caused electrons in graphene to gain (blue beam) and lose ...
