How to control friction in topological insulators

Topological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists at the University of Basel and the Istanbul Technical University have begun investigating ...

Hand-knitted molecules

Molecules are usually formed in reaction vessels or laboratory flasks. An Empa research team has now succeeded in producing molecules between two microscopically small, movable gold tips – in a sense as a "hand-knitted" ...

Another step closer to tunable liquids

Using electrical fields to modify the properties of liquids in contact with a surface can be used in several applications, such as electrophoresis, where an electric current can separate molecules by size. Researchers at ...
