A research team, led by Professor Guntae Kim in the School of Energy and Chemical Engineering at UNIST has announced a breakthrough in technology that efficiently converts liquid ammonia into hydrogen. Their findings have also attracted significant attention from academic research communities owing to its new analysis protocol, capable of finding optimal process environments.

In this study, the research team succeeded in producing green hydrogen (H2) in large quantities with a purity of nearly 100 percent by decomposing liquid ammonia (NH3) into electricity. Besides, according to the research team, such method consumed three times less power than hydrogen made using electrolysis of water.

Ammonia has emerged as an attractive potential hydrogen carrier due to its extremely high e...

The feeding patterns of black holes offer insight into their size, researchers report. A new study revealed that the flickering in the brightness observed in actively feeding supermassive black holes is related to their mass.

Supermassive black holes are millions to billions of times more massive than the sun and usually reside at the center of massive galaxies...

Scientists have recreated the reaction by which carbon isotopes made their way into different organic compounds, challenging the notion that organic compounds, such as amino acids, were formed by isotopically enriched substrates. Their discovery suggests that the building blocks of life in meteorites were derived from widely available substrates in the early solar system.

Their findings were published online in Science Advances on April 28, 2021.

Carbonaceous meteorites contain the building blocks of life, including amino acids, sugars, and nucleobases. These meteorites are potential providers of these molecules to the prebiotic Earth.

The small organic molecules found in meteorites are generally enriched in a heavy carbon isotope (13C)...

Researchers have found a way to use light and a single electron to communicate with a cloud of quantum bits and sense their behaviour, making it possible to detect a single quantum bit in a dense cloud.

The researchers, from the University of Cambridge, were able to inject a ‘needle’ of highly fragile quantum information in a ‘haystack’ of 100,000 nuclei. Using lasers to control an electron, the researchers could then use that electron to control the behaviour of the haystack, making it easier to find the needle. They were able to detect the ‘needle’ with a precision of 1.9 parts per million: high enough to detect a single quantum bit in this large ensemble.

The technique makes it possible to send highly fragile quantum information optically to a nuclear system for storage, and ...
