Star-shaped nanoparticles may help to fight cancer

Together with colleagues, a group of scientists from Immanuel Kant Baltic Federal University synthesized nanostructures of gold and iron oxides that have improved magnetic and optical properties because of their unique star ...

Topological materials become switchable

A donut is not a breakfast roll. Those are two very clearly distinguishable objects: One has a hole, the other does not. In mathematics, the two shapes are said to be topologically different—you cannot transform one into ...

Researchers use light to control magnetic fields at nanoscale

In thin, two-dimensional semiconductors, electrons move, spin and synchronize in unusual ways. For researchers, understanding the way these electrons carry out their intricate dances—and learning to manipulate their choreography—not ...

Exotic electronic effect found in 2D topological material

Jülich researchers have been able to demonstrate an exotic electronic state, so-called Fermi Arcs, for the first time in a 2D material. The surprising appearance of Fermi arcs in such a material provides a link between novel ...

The building blocks for exploring new exotic states of matter

Topological insulators act as electrical insulators on the inside but conduct electricity along their surfaces. Researchers study some of these insulators' exotic behavior using an external magnetic field to force the ion ...
