Ion beams pave way to new kinds of valves for use in spintronics

Researchers have tested a new approach to fabricating spin valves. Using ion beams, the researchers have succeeded in structuring an iron aluminium alloy in such a way as to subdivide the material into individually magnetizable regions at the nanometer scale. The prepared alloy is thus able to function as a spin valve, which is of great interest as a candidate component for use in spintronics.

The thousand-droplets test in artificial cell-scale systems

In the future, an entire chemistry lab could be accommodated in a tiny little droplet. While simple reactions already work in these simplest models of an artificial cell now a group of scientists of the Cluster of Excellence Nanosystems Initiative Munich (NIM) have established and investigated for the first time a complex biochemical system. They discovered a surprising diversity.

Soft nanoporous metal-organic framework materials

Researchers have developed a method to construct a series of soft nanoporous metal-organic framework (MOF) materials by polycatenation of an isoreticular 1D ribbon of rings, and systematically functionalize the pore metrics.

Researchers hijack cancer migration mechanism to 'move' brain tumors

One factor that makes glioblastoma cancers so difficult to treat is that malignant cells from the tumors spread throughout the brain by following nerve fibers and blood vessels to invade new locations. Now, researchers have learned to hijack this migratory mechanism, turning it against the cancer by using a film of nanofibers thinner than human hair to lure tumor cells away.
