Just add Dendrimers, Cellulose and Graphene: New Eco-friendly, Long-lasting Light-emitting Electrochemical Cell

In research that could lead to a new age in illumination, researchers from Japan and Germany have developed an eco-friendly light-emitting electrochemical cells using new molecules called dendrimers combined with biomass derived electrolytes and graphene-based electrodes. Their findings were published in the journal Advanced Functional Materials.

Electroluminescence is the phenomenon where a material emits light in response to a passing electric current. Everything from the screen you’re using to read this sentence to the lasers used in cutting edge scientific research are results of the electroluminescence of different materials...

‘Like a Mirror’: Astronomers Identify most Reflective Exoplanet

The Neptune-sized exoplanet LTT9779b reflects 80 percent of the light from its star, according to Cheops
The Neptune-sized exoplanet LTT9779b reflects 80 percent of the light from its star, according to Cheops.

A scorching hot world where metal clouds rain drops of titanium is the most reflective planet ever observed outside of our Solar System, astronomers said on Monday.

This strange world, which is more than 260 light years from Earth, reflects 80 percent of the light from its host star, according to new observations from Europe’s exoplanet-probing Cheops space telescope.

That makes it the first exoplanet comparably shiny as Venus, which is the brightest object in our night sky other than the Moon.

First discovered in 2020, the Neptune-sized planet called LTT9779b orbits its star in just 19 hours.

Because it is so close, the side of the planet facing its star is a sizzling ...

Unveiling a groundbreaking and accurate AI-based method to classify cardiac function and disease using chest X-Rays. AI (artificial intelligence) may sound like a cold robotic system, but Osaka Metropolitan University scientists have shown that it can deliver heartwarming — or, more to the point, “heart-warning” — support. They unveiled an innovative use of AI that classifies cardiac functions and pinpoints valvular heart disease with unprecedented accuracy, demonstrating continued progress in merging the fields of medicine and technology to advance patient care. The results will be published in The Lancet Digital Health.

Researchers have discovered the most distant active supermassive black hole to date with the James Webb Space Telescope (JWST). The galaxy, CEERS 1019, existed about 570 million years after the big bang, and its black hole is less massive than any other yet identified in the early universe.

In addition to the black hole in CEERS 1019, the researchers identified two more black holes that are on the smaller side and existed 1 billion and 1.1 billion years after the big bang...
