An image of Bi-2212, bismuth-based superconducting wires. (Mark Wallheiser/FAMU-FSU College of Engineering) Researchers used high-resolution scanning electron microscopy to understand how processing methods influence grains in bismuth-based superconducting wires (known as Bi-2212). Those grains form the underlying structures of high-temperature superconductors, and scientists viewing the Bi-2212 grains at the atomic scale ....

Previous image Next image The pursuit of fusion as a safe, carbon-free, always-on energy source has intensified in recent years, with a number of organizations pursuing aggressive timelines for technology demonstrations and power plant designs. New-generation superconducting magnets are a critical enabler for many of these programs, which creates growing need for sensors, controls, and other infrastructure that will allow the magnets to operate reliably in the harsh conditions of a commercial fusion power plant. A collaborative group led by Department of Nuclear Science and Engineering (NSE) doctoral student Erica Salazar recently took a step forward in this area with a promising new method for quick detection of a disruptive abnormality, quench, in powerful high-temperature superconducting (HTS) magnets. Salazar worked with NSE Assistant Professor Zach Hartwig of the MIT Plasma Scie ....
Date Time Australia’s Chief Scientist to speak at Science meets Parliament We are excited to announce that Australia’s Chief Scientist Dr Cathy Foley AO PSM will give the National Press Club Address on 17 March – as the centrepiece of this year’s Science meets Parliament. In her first major speech as Australia’s Chief Scientist, Dr Foley will lay out her ambitious agenda for her term – so register now for SmP. Dr Foley started her term as Australia’s ninth Chief Scientist in January 2021. She comes to the role from a lengthy career in CSIRO – most recently serving as Chief Scientist for the national science agency. ....
