First experimental evidence of tunnelling in fluorine pushes the boundary of our understanding of chemical bonding ...

In a variety of technological applications related to chemical energy generation and storage, atoms and molecules diffuse and ...

Introduce the question students will investigate in this lesson: If atoms have an equal number of protons and electrons, why do atoms bond to other atoms? Why don’t they just stay separate? Begin to ...

By exerting unprecedented control over extremely cold atoms, researchers have put them in a state with several simultaneously ...

Understanding how atoms move across metal surfaces is critical for improving technologies that store and generate energy, ...

By controlling individual atoms, researchers have demonstrated a way to turn previously unwanted atomic motion into an ...

Computational study shows how apical carbons in propellanes and pyramidanes can form hydrogen, halogen, chalcogen, pnictogen ...

Electrons also only travel in edge states for distances less than a nanometer. Rather than trying to observe these minute conditions, the team tried to scale up edge states by working with atoms.

Just as in atoms, and in sharp contrast to bulk semiconductor systems, the electrons in the quantum dot exist only in certain quantized energy states (Fig. 1). Figure 1: Energy levels in a ...

Physicists directly observed ultracold atoms in an 'edge state,' flowing along a boundary without resistance. The research could help physicists manipulate electrons to flow without friction in ...
