to the research group page for Patrick Grant,
Vesuvius Professor of Materials at Oxford University. Our research takes
place at the interface between advanced materials and manufacturing.
Particular applications include electrodes for energy storage and advanced
metallics for power generation.
Many of our research projects are concerned
with solidification behaviour in complex alloys, and/or the use of liquid
metal, ceramic or polymer droplet and powder sprays to create unusual
materials. The group works closely with industry and other universities,
and has many specialised synthesis and fabrication facilities.
is based at Oxford University's Begbroke
Science Park, approximately 5 miles north of Oxford. The Begbroke
Science Park provides large-scale laboratories unavailable in Oxford
- critical for manufacturing research at a meaningful scale - and the
350sqm Advanced Processing Laboratory is the
hub for the group's research.
In summer 2014, the group received a new Thermo K-alpha X-ray photoelectron spectrometer (XPS) to support our work in energy storage materials, as well as other projects across the Department of Materials and our industrial partners.
The XPS technique is very sensitive to surface chemistry and is of particular use in investigating interfacial energy storage mechanisms (intercalation, redox, etc), particularly in the case of supercapacitors. The equipment also allows for rapid transfer of samples, for example from a glovebox, and has a multi-sample stage. The new equipment has already proved valuable in supporting several recent publications (see below).
In January 2014, the UK's Chancellor, George Osborne announced
that 4 business ‘incubator’ centres in Oxford will between them receive
£30 M from government towards of total of £67 M to invest in world leading science and technology.
Visiting the Begbroke Science Park and the group's Advanced Procesing Laboratory,
along with Nicola Blackwood MP, the Chancellor announced over £4 M
to build a new ‘Innovation Accelerator’ for small high tech
manufacturing businesses at Begbroke that specialise in robotics, parts for car
and jet engines and superfast computers. The project, which will receive an additional £7M from Oxford University, will support researchers to get their products ready for market.
Major project areas
Fission and Fusion Power is an EPSRC Programme Grant developing understanding, at the microstructural
level, of the key structural integrity issues which underpin development
and application of alloys for high-flux, high temperature neutron environments.
Our role in the project is to research the manufacture of oxide dispersion
strengthened steels and copper alloys, and ultra-thick tungsten coatings for use in future fusion power
reactors. Key sponsors are the Culham Centre for Fusion Energy (CCFE) and the National Nuclear Laboratory (NNL).
The EPSRC Centre
for Innovative Manufacture in Liquid Metal Engineering - LiME,
involving Brunel and Birmingham Universities, and industrial partners is a major research programme to reduce dependency on primary metals, increase
recycling and boost the performance of castings.
The work at Oxford concerns real-time X-ray synchrotron based imaging of solidification, phase field modelling of crystal growth, and extraction and study of the fine-scale intermetallic compounds involving tramp impurities that control properties. Our aim is to develop a new family of more tolerant alloy-process combinations.
The Quest for Ultimate Electromagnetics using
Spatial Transformations (QUEST) is an EPSRC Programme Grant involving Queen Mary, Exeter and Oxford universities
and focuses on developing practical applications of spatial transformations
for communication, wireless energy transfer, sensor and security applications.
The group is developing the new materials and manufacturing technology
required for practical applications, including the manufacture of graded electrical and magnetic materials using new adaptations of 3D printing, spray deposition, and polymer-based casting. In some arrangments, the structured materials - or meta-materials - produce unusual interactions with microwaves unavailable in conventional materials or composites. We are also studying active meta-materials where their microwave response is controlled by an external stimulus.
The SuperGen Energy Storage Hub is a national collaboration funded by EPSRC for research on all types of storage technologies. Our work focuses on the manufacture
of improved, structured electrodes for batteries and supercapacitors
We are also research new manufacturing-material combinations for grid-scale storage in EPSRC Grand Challenge: Energy Storage for Low Carbon Grids,
led by Imperial College London. Both these projects form part of our contribution to The Energy Storage Research Network. We are also studying the novel manufacturing and performance of Flexible energy storage and generation systems funded by the Korea Institute of Energy Technology Evaluation and Planning (KETEP).
Oxford Energy provides more information on how our work links with Oxford University's wider energy research activities.
