Magnetism meets topology on a superconductor's surface

Electrons in a solid occupy distinct energy bands separated by gaps. Energy band gaps are an electronic "no man's land," an energy range where no electrons are allowed. Now, scientists studying a compound containing iron, ...

Plant-based magnetic nanoparticles with antifungal properties

A team of researchers from Immanuel Kant Baltic Federal University obtained magnetic nanoparticles using sweet flag (Acorus calamus). Both the roots and the leaves of this plant have antioxidant, antimicrobial, and insecticide ...

How metal atoms can arrange themselves on an insulator

In order to produce tiny electronic memories or sensors in the future, it is essential to be able to arrange individual metal atoms on an insulating layer. Scientists at Bielefeld University's Faculty of Chemistry have now ...

Surfaces help quantum switches

The quantum dynamics of hydrogen are central to many problems in nature, being strongly influenced by the environment in which a reaction takes place. In their contribution to PRL, members of the Lise Meitner Group at the ...
