BARBARA ETSCHMANN, JOEL BRUGGER & VANESSA WONG, THE CONVERSATION 24 MAY 2021 Almost 60 years after British nuclear tests ended, radioactive particles containing plutonium and uranium still contaminate the landscape around Maralinga in outback South Australia.

Rambo on behalf of Diamond Light Source Ltd Free to read Unlock In 2020, the most significant application of Soft-condensed matter (SCM) science was, undoubtedly, the development of the COVID vaccines by Pfizer-BioNTech and Moderna which are composed of a synthetic messenger RNA encapsulated within a lipid nanoparticle [1]. SCM science drives continued improvements to quality of life as SCM science is integral to a broad range of industrial sectors. These sectors include food safety and waste, agriculture, polymers, coatings, additive manufacturing, lubricants and additives, personal care, electronics, energy storage, transportation, health and medicine. SCM materials occur over a range of physical states that include liquid, semi-solid, waxes, glasses and aerosols. This necessitates a complementary and diverse suite of instrumentation and methodologies for understanding how molecular de ....
