Spins in graphene with a hedgehog texture

At a surface or interface the electron spin can form specific patterns but it remains in the surface plane. Researchers have now succeeded in turning the spin out of the plane, and they explain why this is a principle property.

Making polymer nanostructures from a greenhouse gas

Scientists have introduced a two-step, one-pot conversion of CO2 and epoxides to polycarbonate block copolymers that contain both water-soluble and hydrophobic regions and can aggregate into nanoparticles or micelles.

A new type of modulator for the future of data transmission

Researchers present a novel modulator that is a hundred times smaller and that can, therefore, be easily integrated into electronic circuits. Moreover, the new modulator is considerably cheaper and faster than common models, and it uses far less energy.

Superconducting qubit and magnetic sphere hybrid

Researchers have demonstrated that it is possible to exchange a quantum bit, the minimum unit of information used by quantum computers, between a superconducting quantum-bit circuit and a quantum in a magnet called a magnon.
