Sandberg L, Haubro M, Krighaar K, Edberg R, Fjellvag I, Guthrie M, et al.
Rev Sci Instrum . 2023 Oct; 94(10). PMID: 37787628
We provide an overview of a pressure cell designed to apply uniaxial pressure to single crystals for the study, by neutron scattering techniques, of strongly correlated magnetic systems and, in...

Guthrie M
J Phys Condens Matter . 2015 Mar; 27(15):153201. PMID: 25789450
The ability to manipulate structure and properties using pressure has been well known for many centuries. Diffraction provides the unique ability to observe these structural changes in fine detail on...

Skinner L, Benmore C, Weber J, Williamson M, Tamalonis A, Hebden A, et al.
Science . 2014 Nov; 346(6212):984-7. PMID: 25414311
Uranium dioxide (UO2) is the major nuclear fuel component of fission power reactors. A key concern during severe accidents is the melting and leakage of radioactive UO2 as it corrodes...
