Our diamond anvil cell<\/a> (DAC) high pressure facilities are amongst the best in the UK.  We have a number of DACs custom-constructed to our own designs, primarily for optical spectroscopy and X-ray powder diffraction at temperatures from ambient temperature up to 1000 K.  Our DACs are equipped with diamond culets up to 1 mm diameter for accurate pressure control at (relatively speaking) low pressures up to about 5 GPa (50 kbar), and also with bevelled diamonds with culet side down to 0.1 mm to obtain extremely high static pressures (165 GPa, 1.65 megabar).  High temperatures up to 1000 K are obtained using resistive heating with feedback to ensure temperature stability.<\/p>\n\n\n\n

We have facilities for reliable cryogenic loading of diamond anvil cells (for samples such as methane which are gaseous at ambient conditions), and a custom-constructed spark eroder<\/a> (electric discharge) machine for preparing the sample chambers in rhenium and stainless steel gaskets.<\/p>\n\n\n\n

Since the diamond anvil cell high pressure facility was established in 2013 data obtained using the equipment (either from Raman scattering in-house, electrical resistivity measurements at other laboratories or X-ray diffraction at central facilities) have contributed to a large number of research publications.  Some highlights: 2020 JRS Read et al.<\/a>, 2017 PRE Smith et al.<\/a>, 2015 ACS Nano Smith et al<\/a>.<\/p>\n\n\n\n

We are available to perform contractual \/ consultancy work for external users and are open to new academic collaborations.  Diamond anvil cell experiments also form a key part of many Ph.D. and M.Res. research projects undertaken in the group.  Please contact j.e.proctor@salford.ac.uk<\/a> to enquire about using our high pressure facilities, or working with us to develop your own facilities.<\/p>\n","protected":false},"excerpt":{"rendered":"
