New insights could help tame speedy ions in fusion plasmas

To create a practical fusion energy reactor, researchers need to control particles known as fast ions. These speedy ions, which are electrically charged hydrogen atoms, provide much of the self-heating ability of the reactor ...

Reducing open-circuit voltage loss in organic solar cells

Researchers at Institute for Molecular Science in Japan report that organic solar cells (OSCs) with high mobility and highly crystalline donor (D) and acceptor (A) materials were able to reduce an open-circuit voltage (VOC) ...

Tiger sharks revealed as lazy predators

One of the ocean's most feared predators – the tiger shark—has been revealed as a relaxed and sometimes lazy hunter by scientists studying their behaviour.

New coating could have big implications for lithium batteries

Building a better lithium-ion battery involves addressing a myriad of factors simultaneously, from keeping the battery's cathode electrically and ionically conductive to making sure that the battery stays safe after many ...

The sun in 2018

This montage of 365 images shows the changing activity of our sun through the eyes of ESA's Proba-2 satellite during 2018. The images were taken by the satellite's SWAP camera, which works at extreme ultraviolet wavelengths ...
