- Quasi-2D spin-Peierls transition through interstitial anionic electrons in K(NH₃)₂
In a paper published in Science Bulletin, a Chinese team of scientists predicts a novel electride K(NH3)2, with interstitial electrons distributed at cages formed by six ammonia molecules and forming a quasi-2D triangular lattice. They have revealed that this material undergoes a spin-Peierls phase transition under moderate pressures.
- IRIS beamline at BESSY II gets a new nanospectroscopy end station
The IRIS infrared beamline at the BESSY II storage ring now offers a fourth option for characterizing materials, cells and even molecules on different length scales. The team has extended the IRIS beamline with an end station for nanospectroscopy and nanoimaging that enables spatial resolutions down to below 30 nanometers. The instrument is also available to external user groups.
- NASA’s Voyager 1 probe calls home after five months
For the first time in five months, NASA’s Voyager 1 spacecraft is returning usable data about the health and status of its onboard engineering systems. The next step is to enable the spacecraft to begin returning science data again. The probe and its twin, Voyager 2, are the only spacecraft to depart the Solar System and fly in interstellar space.
- NGC 4361: A planetary nebula to crow about
NGC 4361 in Corvus is a bit of an horizon-hugger at mid-northern latitudes, but it’ll reward determined observers.
- Hundreds of previously unrecorded monuments discovered in Baltinglass, Ireland
A recent archaeological survey in the Baltinglass landscape of County Wicklow, Ireland, has revealed hundreds of previously unrecorded monuments. Published in the journal Antiquity, the study, led by Dr. James O’Driscoll from the University of Aberdeen, employed advanced LiDAR technology to reveal intricate details of the landscape, uncovering structures that had been hidden for millennia The post Hundreds of previously unrecorded monuments discovered in Baltinglass, Ireland appeared first on Archaeology News Online Magazine.
- Enhancing fusion reactor control through combined plasma management techniques
Los Angeles CA (SPX) Apr 19, 2024 Researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) are advancing fusion technology by integrating two established plasma control methods-electron cyclotron current drive (ECCD) and resonant magnetic perturbations (RMP). This combination has shown promising results in improving plasma management, crucial for generating electricity through fusion. The t
