Three teams of researchers at Clemson University have joined forces to unravel some of the mysteries surrounding perovskite nanocrystals, which are semiconductors with numerous applications, including LEDs, lasers, solar cells and photodetectors.

A research article titled “The correlation between phase transition and photoluminescence properties of CsPbX3 (X=Cl, Br, I) perovskite nanocrystals” recently appeared in Nanoscale Advances, an open-access journal published by the Royal Society of Chemistry...

An international team of researchers have discovered a dense, cold gas that’s been shot out from the centre of the Milky Way “like bullets.”

Exactly how the gas has been ejected is still a mystery, but the research team, including Professor Naomi McClure-Griffiths from The Australian National University (ANU), say their findings could have important implications for the future of our galaxy.

“Galaxies can be really good at shooting themselves in the foot,” Professor McClure-Griffiths said.

“When you drive out a lot of mass, you’re losing some of the material that could be used to form stars, and if you lose enough of it, the galaxy can’t form stars at all anymore.

“So, to be able to see hints of the Milky Way losing this star forming gas is kin...

For decades, physicians have known that many kinds of cancer cells often spread first to lymph nodes before traveling to distant organs through the bloodstream. New research from Children’s Medical Center Research Institute at UT Southwestern (CRI) provides insight into why this occurs, opening up new targets for treatments that could inhibit the spread of cancer.

The study, published today in Nature, found melanoma cells that pass through the lymph nodes pick up a protective coating, allowing them to survive high levels of oxidative stress in the blood and go on to form distant tumors.

The discovery of an unprecedented physical effect in a new artificial material marks a significant milestone in the lengthy process of developing ‘made-to-order’ materials and more energy-efficient electronics.

We are surrounded by electronic devices. Transistors are used to power telephones, computers, televisions, hi-fi systems and game consoles as well as cars, airplanes and the like. Today’s silicon-based electronics, however, consume a substantial and ever-increasing share of the world’s energy.

A number of researchers are exploring the propert...
