Hollow-core fibers for precise positioning in space

The vision of cars that drive or planes that fly themselves can only become true if the electronics on board can determine where they are in space, anytime and with reliable precision. In the aerospace sector, this job is ...

Identifying a new, cleaner source for white light

When early humans discovered how to harness fire, they were able to push back against the nightly darkness that enveloped them. With the invention and widespread adoption of electricity, it became easier to separate heat ...

Image: ESO telescope images a spectacular cosmic dance

ESO's Very Large Telescope (VLT) has imaged the result of a spectacular cosmic collision—the galaxy NGC 7727. This giant was born from the merger of two galaxies, an event that started around a billion years ago. At its ...

Air-stability of sodium-based layered-oxide cathode materials

Sodium ion batteries are considered to be one of the most promising alternative systems to lithium-ion batteries, especially for large scale applications. Sodium-based transition-metal oxides with layered structure have been ...

Highly insulating alkane rings with destructive σ-interference

Destructive quantum interference (DQI) provides the possibility to significantly suppress the leakage current in the OFF state of molecular devices. However, the DQI in π-conjugated molecules cannot exhibit ultralow conductance ...

Do wind instruments disperse COVID aerosol droplets?

During the COVID-19 pandemic, many live musical events and festivals were postponed and even canceled to protect musicians and audience members. When they started performing again, many groups resorted to performing with ...
