A research team led by Lawrence Berkeley National Laboratory (Berkeley Lab) has developed “supramolecular ink,” a new technology for use in OLED (organic light-emitting diode) displays or other electronic devices. Made of inexpensive, Earth-abundant elements instead of costly scarce metals, supramolecular ink could enable more affordable and environmentally sustainable flat-panel screens and electronic devices.

“By replacing precious metals with Earth-abundant materials, our supramolecular...

Records of Cometary Dust Hitting the Asteroid Ryugu

The Hayabusa2 mission that collected samples from the asteroid Ryugu has provided a treasure trove of insights into our solar system. After analyzing samples further, a team of researchers have unearthed evidence that cometary organic matter was transported from space to the near-Earth region.

Ryugu is a near-Earth asteroid that gained significant attention when the Japanese Hayabusa2 mission collected samples and returned them to Earth...

Low-frequency Ultrasound can Improve Oxygen Saturation in blood

Research conducted by a team of scientists from Kaunas universities, Lithuania, revealed that low-frequency ultrasound influences blood parameters. The findings suggest that ultrasound’s effect on haemoglobin can improve oxygen’s transfer from the lungs to bodily tissues.

The research was undertaken on 300 blood samples collected from 42 pulmonary patients. The samples were exposed to six different low-frequency ultrasound modes at the Institute of Mechatronics of Kaunas University of Technology (KTU).

The changes in 20 blood parameters were registered using the blood analysing equipment at the Lithuanian University of Health Sciences (LSMU) laboratories. For the prediction of ultrasound exposure, artificial intelligence, i.e...

New research sheds light on a Phenomenon known as ‘False Vacuum Decay’

Image of the Universe
Vacuum decay is thought to play a central role in the creation of space, time and matter in the Big Bang, but until now there has been no experimental test
 
Professor Ian Moss

An experiment conducted in Italy, with theory support from Newcastle University, has produced the first experimental evidence of vacuum decay.

In quantum field theory, when a not-so-stable state transforms into the true stable state, it’s called “false vacuum decay.” This happens through the creation of small localised bubbles.

While existing theoretical work can predict how often this bubble formation occurs, there hasn’t been much experimental evidence.

Now, an international research team involving Newcastle University scientists has for the first observed these bubbles forming in carefully controlled a...
