Creating eco-friendly superconductors with MgB2 super magnets
Newswise — MgB2 is a binary compound that acts as a superconductor at a moderate temperature of around -234°C. This temperature can be achieved using inexpensive coolants like liquid hydrogen…
Differing device personalities come together for future quantum computing networks
Credit: NIST We’re building the tools to trap ions and watch them glow (or not). The art-deco-esque device shown above is a combined trap for ions (charged atoms) and detector…
Researchers develop clever algorithm to improve our understanding of particle beams in accelerators
Newswise — Whenever SLAC National Accelerator Laboratory’s linear accelerator is on, packs of around a billion electrons each travel together at nearly the speed of light through metal piping. These…
Zeroing in on a Fundamental Property of the Proton’s Internal Dynamics
The Science Inside the proton are elementary particles called quarks. Quarks and protons have an intrinsic angular momentum called spin. Spin can point in different directions. When it is perpendicular…
Cheap cobalt catalyst makes record ammonia
Newswise — Ammonia (NH3) is one of the most widely produced chemicals in the world, with a production of over 187 million tons in 2020. About 85% of it is…
Newly observed effect makes atoms transparent to certain frequencies of light
Artist’s visualization of a laser striking atoms in an optical cavity. Credit: Ella Maru Studio A newly discovered phenomenon dubbed “collectively induced transparency” (CIT) causes groups of atoms to abruptly…

Quantum scientists achieve state-of-the-art defect-free atom array
Arrays of neutral atoms are a promising platform for quantum simulation. Asst Prof Loh Huanqian and her group can precisely assemble large arrays of singly-trapped rubidium atoms, as shown in…
Scientists use laser fields to precisely measure and control electron emission of metals
Credit: Unsplash/CC0 Public Domain By superimposing two laser fields of different strengths and frequency, the electron emission of metals can be measured and controlled precisely to a few attoseconds. Physicists…
