Description | Our work has led to two distinct developments: first new barocaloric materials discovery, and second, significant advances in understanding the driving mechanism behind the barocaloric effect. We have identified a number of new families of barocaloric materials. The wide range of different materials increases the likelihood that one of them will prove to be suitable for large-scale commercial and industrial use as an environmentally friendly refrigerant. We therefore hope that our work will facilitate the phasing out of refrigerants that are greenhouse gases and/or ozone depletors. We have furthermore advanced our understanding of the atomic-scale mechanism for the barocaloric effect, which will help to tune these materials' properties and to identify still more candidate materials. |
Exploitation Route | We anticipate that our work will be relevant both to academic scientists designing new materials and to commercial exploitation for heat transport and storage. |

Results and Impact | I was interviewed by Gavin Costigan for the Foundation for Science and Technology's podcast about ISIS, neutron science and more specifically about my research on barocalorics. The podcast is hosted on their website and can be accessed by anybody interested. My aims were to promote neutron scattering within the UK and to demonstrate how they are very well suited towards barocaloric research, hoping to raise knowledge and interest in the general public and policy makers. |
