Identifying organic compounds with visible light

Researchers from the Universidad de Santiago de Chile and the University of Notre Dame, working with machine learning, have devised a method to identify organic compounds based on the refractive index at a single optical ...

Microscopic chains that mimic DNA

Circular polycatenanes are chains that can move and change shape: they twist, stretch and wrap around themselves. Three physicists of the European Eutopia Cost network, coordinated by UniTrento, have dedicated themselves ...

Making mini-magnets that induce a quantum anomalous Hall effect

A new device has been fabricated that can demonstrate the quantum anomalous Hall effect, in which tiny, discrete voltage steps are generated by an external magnetic field. This work may enable extremely low-power electronics, ...
