Using Spektr-RG and Fermi space observatories, German astronomers have investigated the supernova remnant SNR G309.8+00.0 in X-rays and gamma rays. Results of the new study, presented June 25 on the preprint server arXiv, ...
Magnetization can be switched with a single laser pulse. However, it is not known whether the underlying microscopic process is scalable to the nanometer length scale, a prerequisite for making this technology competitive ...
Using an instrument on the 4.1-meter Southern Astrophysical Research Telescope, researchers have obtained the first astronomical spectrum using skipper charge-coupled devices (CCDs).
Around the world this summer, professional and amateur astronomers alike will be fixed on one small constellation deep in the night sky. But it's not the seven stars of Corona Borealis, the "Northern Crown," that have sparked ...
Transistors are the basis for microchips and the whole electronic industry. The invention of transistors, by Bardeen and Brattain in 1947, awarded with a Nobel prize, is regarded as one of the most important discoveries of ...
If alien technological civilizations exist, they almost certainly use solar energy. Along with wind, it's the cleanest, most accessible form of energy, at least here on Earth. Driven by technological advances and mass production, ...
The junction composed of traditional metals and 2D semiconductors is a key component of semiconductor devices.
As a typical two-dimensional material, MoS2 exhibits unique optical and electrical properties due to its atomic thickness in the vertical dimension, making it a research hotspot in the field of optoelectronic detection.
The need for sustainable and environment-friendly solutions has accelerated the global demand for green and renewable technologies. In this regard, semiconductor photocatalysts have emerged as an attractive solution, owing ...
A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA's Fermi Gamma-ray ...
