Quantum dots form ordered material

Quantum dots are clusters of some 1,000 atoms which act as one large "super-atom." It is possible to accurately design the electronic properties of these dots just by changing their size. However, to create functional devices, ...

80-year-old mystery in static electricity finally solved

Historically, contact electrification (CE) was humanity's first and only source of electricity up until around the 18th century, yet its true nature is still elusive. Today it is considered a core component of technologies ...

Electron slow motion: Ion physics on the femtosecond scale

How do different materials react to the impact of ions? This is a question that plays an important role in many areas of research—for example, in nuclear fusion research, when the walls of the fusion reactor are bombarded ...

Study finds nickelate superconductors are intrinsically magnetic

Electrons find each other repulsive. Nothing personal—it's just that their negative charges repel each other. So getting them to pair up and travel together, like they do in superconducting materials, requires a little ...
