All cultures have music in some form, and the instruments used to produce it - and the tonal qualities they are designed to produce – change over time. Historical instruments are an important part of our cultural heritage, and scientific examination can help us to determine lost details about how the instruments were manufactured, and when, and provide us with important information to assist with their conservation.
Metal-amine solutions have been a fascinating curiosity since their discovery by Sir Humphry Davy in 1808. These colourful ‘metal solutions’ are in a class of their own because they contain solvated electrons, and therefore offer us the opportunity to study fundamental physical phenomena.
A mystery surrounding three stone-like objects found within the pelvic region of a 12,000-year-old human skeleton has been solved thanks to the analytical capability of the UK’s neutron beam research facility.
Scientists from the Universities of Bath and Cambridge have developed a new, green synthetic route for cerium oxide (ceria) – an important component in catalytic converters and solid oxide fuel cells – using neutron diffraction to determine the mechanism of reaction.
