Attaining precise sample alignment under extreme conditions

The exact angular alignment of sample materials for the determination of their physical properties under extreme conditions is often difficult. Engineer Stefan Findeisen and physicist Dr. Hannes Kühne from the Helmholtz-Zentrum ...

Neutral particles a drag on disruptive plasma blobs

For decades, scientists have been working to harness clean, renewable fusion energy, which occurs naturally in stars like our sun. Using strong magnetic fields to confine hot plasmas within a donut-shaped device called a ...

Novel quantum effect discovered in naturally occurring graphene

Usually, the electrical resistance of a material depends very much on its physical dimensions and fundamental properties. Under special circumstances, however, this resistance can adopt a fixed value that is independent of ...

Japanese astronomers investigate magnetar XTE J1810-197

Using four radio telescopes, astronomers from the National Astronomical Observatory of Japan and elsewhere have conducted multi-frequency multi-epoch radio observations of a radio-loud magnetar known as XTE J1810-197. Results ...

Negative triangularity—a positive for tokamak fusion reactors

Tokamak devices use strong magnetic fields to confine and to shape the plasma that contains the fuel that achieves fusion. The shape of the plasma affects the ease or difficulty of achieving a viable fusion power source. ...

Strong magnetic fields change how friction works in plasma

Friction in plasma gets weird in the presence of very strong magnetic fields, a team of plasma researchers at the University of Michigan has shown. The findings could affect fusion energy strategies and the development of ...
