A simple electrical method shows how protein nanowires carry both electrons and ions, offering a clearer way to design soft, ...

Attosecond science, honored with the 2023 Nobel Prize in Physics, is transforming our understanding of how electrons move in atoms, molecules, and solids. An attosecond – equivalent to a billionth of ...

Key learning points Electrical charges What are free electrons? Cell polarity Conventional current direction Electrons orbit the nucleus. An atom has a neutral charge, because it contains the same ...

For the first time, scientists have used ultrafast X-ray flashes to take a direct image of a single electron as it moved during a chemical reaction. In the new study, published Aug. 20 in the journal ...

Scientists built a nano switch that controls excitons, chargeless quantum quasiparticles, at room temperature.
