Rechargeable lithium metal batteries with increased energy density, performance, and safety may be possible with a newly-developed, solid-electrolyte interphase (SEI), according to Penn State researchers. As the demand for higher-energy-density lithium metal batteries increases – for electric vehicles, smartphones, and drones – stability of the SEI has been a critical issue halting their advancement because a salt layer on the surface of the battery’s lithium electrode insulates it and conducts lithium ions.

“This layer is very i...

Massive Twin Star discovered Snuggling Close to its Stellar Sibling

2MASS observations (background image) revealed a highly reddened source back in 2003 indicating the massive young nature of PDS 27. PIONIER on VLTI provides 2,000 times higher angular resolution making it possible to resolve PDS 27 as a binary system for the first time in 2019.

Astronomers have discovered a binary star system with the closest high-mass young stellar objects ever measured, providing a valuable “laboratory” to test theories on high mass binary star formation.

An international team led by the University of Leeds has determined the distance between the massive young star PDS 27 and its orbiting stellar companion to be just 30 astronomical units away or 4.5 billion km...

New Optical Imaging system could be deployed to find Tiny Tumors

MIT researchers have devised a way to simultaneously image in multiple wavelengths of near-infrared light, allowing them to determine the depth of particles emitting different wavelengths.

Near-infrared technology pinpoints fluorescent probes deep within living tissue; may be used to detect cancer earlier. Many types of cancer could be more easily treated if they were detected at an earlier stage. MIT researchers have now developed an imaging system, named “DOLPHIN,” which could enable them to find tiny tumors, as small as a couple of hundred cells, deep within the body.

In a new study, the researchers used their imaging system, which relies on near-infrared light, to track a 0...

Researchers at Delft University of Technology have created a quantum circuit that enables them to listen to the weakest radio signal allowed by quantum mechanics. This new quantum circuit opens the door to possible future applications in areas such as radio astronomy and medicine (MRI). It also enables researchers to do experiments that can shed light on the interplay between quantum mechanics and gravity.

We have all been annoyed by weak radio signals at some point in our lives: our favourite song in the car turning to noise, being too far away from our wifi router to check our email...
