Neutron Science T his year, we selected five remarkable highlights of the neutron technique that seek to answer varied scientific questions about the fundamental properties of magnetic and energy materials on an atomic scale, and for medical applications on a nanometer scale. In answering these questions, neutrons help spur innovations that improve our daily lives such as new methods of data storage, materials with small or even zero thermal expansion, cost- effective all-solid-state battery material and more effective drug-delivery systems. Using the capability of neutron instruments, researchers count scattered neutrons, measure their energies and the angles at which they are scattered, and map their final position, which makes it possible for scientists to glean details about the nature of materials. The selected remarkable studies were performed by our user communities; they completed their outstanding work at OPAL, ANSTO, using neutron instruments at the state of the art in the year 2021. Four highlights are from the neutron powder diffractometer ( ECHIDNA and WOMBAT ), which are magnetic materials reported by Wei-Tin Chen, Hung-Duen Yang and Xianran Xing; the solid-state battery material was reported by Chen Ma. In the other highlights that applied used the SANS instruments BILBY showed the potential of new novel materials for a drug-delivery system by Kuen- Song Lin. (by Shih-Chun Chung)
