Our research activities receive strong support from a wide range of funders. For example, during the period 2008-2013, the Materials & Physics Research Centre was awarded total funding in the region of £6.2 million. Key funding highlights were:
- EPSRC grant fundings (with Royal Society, British Academy and Royal Society of Edinburgh) amounting to £2,631,000. It should be noted that this portfolio includes two Case awards and two Knowledge Transfer Partnerships, indicating the effectiveness of our industrial links;
- FP6/7 European funding in chemical vapour deposition and hydrogen storage, with grants totalling £1,088,250. These each form part of large European collaborations and Centre staff have acted as both Coordinator (e.g. in HyTRAIN) and Work-Package Leaders (e.g. in NESSHy (2), HySIC, N2P and PLIANT) in connection with these grants;
- Northwest Regional Development Agency (NWDA) and central government funding. For example, funding for the Joule (Energy Research) Centre totalled £1,738,504 – which included a large direct NWDA grant to build the Energy House. This major project involved building a typical Salford terrace house within a concrete vault. The house has been fully equipped with temperature sensors and can be exposed to carefully-controlled external weather profiles, so that it can be used to evaluate retrofit thermal insulation under typical reproducible conditions. The facility is now widely recognised as providing an authoritative measure of the effectiveness of retrofitting thermal insulation and is being used by a wide range of commercial collaborators;
- Awards to Centre members for use of Central Facilities – particularly ISIS at the Rutherford Appleton laboratory in Oxfordshire, the ILL (Institut Laue-Langevin in Grenoble, France) and the UK’s national synchrotron (the Diamond Light Source). This funding in kind amounts to £824,968, and was awarded within an environment of strong international competition for the limited number of instrument-days available at such facilities. Moreover, two of our ISIS experiments have been selected by the facility as scientific highlights.

We are extremely well served with respect to the provision and operation of specialised infrastructure and facilities. Our researchers benefit from the specialist facilities outlined below, which in total cost our University just over £1.5 million annually to run. In addition, we have benefited from University capital expenditure of just over £5 million through the 2008-2013 period, which has been used to augment our state-of-the-art provision.
- Salford Analytical Services (SAS) is responsible for operating a range of modern characterisation equipment – XRD, SEM, MS, TEM, TGA, DSC, NMR, etc. While SAS also accepts commercial contracts, their equipment is made available to our Research Centre members. The unit is staffed by three experienced technical officers who maintain and enhance our modern equipment base.
- The Research Centre also maintains an in-house High Performance Computing facility and associated workstations which, in conjunction with our access to the National Computing Facilities, supports the computational modelling research.
- A Video Feedback Laboratory has been developed to support theoretical modelling activities, and is also used within our programmes of Public Understanding and Outreach.
- A High Pressure Gas Laboratory has been set up for investigations of hydrogen absorption and for hydrogen storage applications (automated gravimetric and volumetric instrumentation).
- Atmospheric Pressure Chemical Vapour Deposition (APCVD) Laboratories have been established for developing new surface coating techniques with greater application to industrial wide area in-line processes. This followed the completion of a Wolfson award for refurbishment, and forward research in the APCVD laboratories that includes increasing both the range of materials possible and their thin film functionalities.
- A Laser Laboratory is fully equipped for operating high power lasers, including a femto-second pump probe facility, in a safe environment. A new Raman Scattering Facility has recently been commissioned, specifically designed for use with high pressure diamond anvil cells.
A significant proportion of our research is focused on the area of renewable technologies, including photovoltaics and energy storage systems. Part of the outputs from our research contributes to reducing the environmental impact of our main university campus. The University has an Energy Team dedicated to reducing the carbon footprint of the campus and has adopted technologies developed by our Research Centre. This work is focused on the Energy House, described above.
A selection of specific Materials & Physics research equipment is listed on the Physics Facilities page.
