    Single-qubit sensing puts new spin on quantum materials discovery

    Working at nanoscale dimensions, billionths of a meter in size, a team of scientists led by ORNL revealed a new way to measure high-speed fluctuations in magnetic materials. Knowledge obtained by these new measurements could be used to advance technologies ranging from traditional computing to the emerging field of quantum computing.

    Hidden Nature of Spin Interactions in Ferromagnet Revealed

    Scientific Achievement: Hidden spin fluctuations in a room-temperature ferromagnet consistent with three-dimensional spin interactions were unveiled by NV magnetometry and relaxometry.Significance and Impact: The power-law scaling observed in the magnetic texture of Sr2FeReO6 provides new opportunities to understand how local spin-fluctuations become correlated near quantum and classical phase transitions.DOI: 10.1021/acs.nanolett.4c05401

    Closed-loop recycling of semi-aromatic polyesters upcycled from poly(ethylene terephthalate

    Scientific Achievement: Via selective deconstruction (by protic ionic salts), post-consumer plastic waste was converted into functional molecules that can serve as building blocks for new polymer materials with built-in closed-loop recyclability.Significance and Impact: This new strategy shows that it is possible to use waste plastic as a feedstock to prepare useful molecules beyond the polymer’s component monomers, making the development of novel, upcycled circular plastics possible.DOI: 10.1016/j.xcrp.2023.101734
