ISIS is the world’s most successful pulsed spallation neutron source. The facility provides beams of neutrons and muons that enable scientists to probe the microscopic structure and dynamics of matter.
The benefits of neutron scattering coupled with the strengths of the ISIS pulsed source have been responsible for the emergence of a world-class research programme at the facility, covering topics at the forefront of Physics, Chemistry, Materials Science, Earth Science, Engineering and Biology. Examples of ISIS science are presented in this section.
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.
Neutron scattering at ISIS gives a unique insight into the geological processes of the Earth's surface and core, and is also being used to answer current questions about the Earth's natural environment.
Chemistry applications of ISIS include studies of catalyst action, the behaviour of ions in solution, atmospheric reactions, radical reactions, molecular dynamics, liquid dynamics, hydrogen bonding . . . to name but a few.
Soft matter encompasses a wide range of substances including polymers, surfactants (including detergents), liquid crystals, micelles (clumps of polar molecules), and microemulsions. All of these share the same basi properties – weak interactions between structural units and large numbers of ways to arrange themselves internally. And when they are touched, they actually feel soft.
Small angle neutron scattering is a neutron technique able to probe structures at length scales from around 1 nanometre to more than 100 nanometres. It has a wide range of applications from studies of polymers and biological molecules to nanoparticles to microemulsions and liposomes used for cosmetics and drug delivery.
