Light-steering of spin-polarized currents in topological insulators

Topological insulators are a fascinating group of materials. A spin-polarization occurs, as soon as an electric current flows in the material. Scientists have measured this now for the first time optically at room temperature.

Synthetic 'virus' to kill bacteria

Scientists have developed a synthetic 'virus' that kills bacteria on first contact.

Superconducting synapse may be missing piece for 'artificial brains'

Researchers have built a superconducting switch that 'learns' like a biological system and could connect processors and store memories in future computers operating like the human brain.

New nanomedicine methode prevents premature nanoparticle breakdown

Nanoparticles that transport medicines to a specific part of the human body are usually broken down in the liver prematurely. Researchers have discovered a new method to prevent this from happening.

Antiferromagnets prove their potential for spin-based information technology

Physicists demonstrate technologically feasible read-out and writing of digital information in antiferromagnets / Basic principle for ultrafast and stable magnetic memory.

Flexing for the next silicon wave

Ultrathin, rigid silicon segments that are wired through interdigitated metal contacts produce ultraflexible high-performance solar cells.

Let liquid fingers point the way

Gold nanospheres can be manipulated on surfaces with nanometer precision using the effects of solvent evaporation.
