Materials that have long range magnetic order are fundamental to modern technologies, including data storage devices, space
research, cancer therapy and biomedical imaging techniques. Future miniaturisation of these components depends on designing
molecules that behave in the same way as larger magnets, and to do this we need an improved understanding of the connection
between molecular structures and their resulting properties.
Although high-temperature- and high-magnetic-field-based ...

Building on previous work conducted at Diamond, researchers have used X-ray Pair Distribution Function (XPDF) on the I15-1 beamline
to probe the structure of a Metal Organic Framework (MOF) in its glassy state, from which they inferred the structure of its liquid form.
MOFs are crystalline materials, which are receiving a lot of interest due to their porous nature, which allows them to accommodate
guest molecules within their structure. Potential applications include drug delivery, ...

Chemistry drastically changes at very high pressures, allowing exotic types of chemical interactions leading to the formation of
novel materials. For mixtures of iron (Fe) with a significant amount of nitrogen (N), theoretical calculations suggested that new
Fe-N compounds could be synthesised at high pressures, and are expected to have enhanced properties such as increased hardness,
superconductivity, or the ability to act as a catalyst.
A team of researchers used I15 to carry out this ...

The world currently relies on coal, oil and gas, not only for fuel but also as raw materials for the production of chemicals. With reserves of these fossil fuels running out, and a growing awareness of the CO2 pollution their use causes, it is becoming increasingly important to develop sustainable carbon sources.

Aerosols – tiny particles in the air – are key to the formation of clouds, as all cloud droplets form when water droplets condense around aerosols.

The surfaces of materials can host unique electronic properties, where the electrons behave very differently from the interior. All electrons possess a magnetic moment, their spin, but in most non-magnetic materials electrons with different spins behave in the same way.

Synchrotron light sources produce a strong and stable pulsed beam, for which the pulse sequence is dependent on the circumference of the storage ring. Many experiments only require some of the pulses, including ‘pump and probe’ experiments that activate a process and then measure it.

The Dzyloshinskii-Moriya interaction (DMI) was first introduced in 1957 to explain ‘weak ferromagnetism’.

Spin-orbit torque (SOT) arises from spin-orbit coupling in heavy metal/ferromagnet bilayers, and can be used to control the magnetisation direction. It is of considerable interest as a way to efficiently switch the magnetisation of spintronic devices, which have advantages over traditional electronic devices, including non-volatile memory and logic applications. In order to engineer materials with enhanced SOT, for lower power consumption, scientists are investigating the microscopic origin ...

To design such small molecules, a detailed map of the interactions between GLP-1 and its receptor was needed.
