Emerging forms of thin-film device technologies that rely on alternative semiconductor materials, such as printable organics, nanocarbon allotropes and metal oxides, could contribute to a more economically and environmentally sustainable IoT, a KAUST-led international team suggests.

Their paper is published in the journal Nature Electronics.

The IoT is set to have a major impact on daily life and many industries...

Planetary Interiors in TRAPPIST-1 System could be affected by Solar Flares

Credit: NASA/JPL-Caltech

In a recent study published in the Astrophysical Journal Letters, an international team of researchers led by the University of Cologne in Germany examined how solar flares erupted by the TRAPPIST-1 star could affect the interior heating of its orbiting exoplanets.

This study holds the potential to help us better understand how solar flares affect planetary evolution. The TRAPPIST-1 system is an exoplanetary system located approximately 39 light-years from Earth with at least seven potentially rocky exoplanets in orbit around a star that has 12 times less mass than our own sun. Since the parent star is much smaller than our own sun, then the the planetary orbits within the TRAPPIST-1 system are much smaller than our own solar system, as well...

This year’s Nobel Prize in Physics celebrated the fundamental interest of quantum entanglement, and also envisioned the potential applications in “the second quantum revolution”—a new age when we are able to manipulate the weirdness of quantum mechanics, including quantum superposition and entanglement...

The Chang’e-5 mission touched down in the Mons Rümker region of the northern Oceanus Procellarum of the moon and returned 1.731 kg of lunar regolith. Recognizing exotic clasts (i.e., non-Chang’e-5 locally derived materials) in the Chang’e-5 regolith could provide critical information about the lithological diversity and regolith gardening process in the young mare region of the moon.

Recently, Dr. Zeng Xiaojia, Prof. Li Xiongyao and Prof. Liu Jianzhong from the Institute of Geochemistry of the Chinese Academy of Sciences (IGCAS) have identified seven exotic igneous clasts in Chang’e-5 samples from more than 3,000 of Chang’e-5 regolith particles.

This work was published in Nature Astronomy on ...
