Our research with the particle physics rolling grant at Sheffield attempts to progress understanding of some of the most important questions concerning the origins and make-up of the Universe. One of these big questions is to understand what gives fundamental particles their mass. Part of our work on the huge ATLAS experiment at the Large Hadron Collider (LHC) at CERN in Geneva is aimed at this question, in particular to see if the famous Higgs Boson particle exists. The best theories we have to explain particle mass predict that it should be there. We will play a key role in analysing the vast amount of data soon expected to make this exciting discovery. Another search at ATLAS will be to determine if the so-called supersymmetry (SUSY) theory is correct. This is our best prospect for understanding how particles interact at high energy and itself predicts a new class of particles. The concept states that for every known fundamental particle there exists a super-partner particle. We worked for many years developing the key silicon technology now installed in ATLAS to search for these particles. Now we are ready with our software to play a key role in analysing the data that will hopefully discover that they exist. One of the implications of SUSY theory is the likelihood that the most stable new particle, the so-called lightest supersymmetric particle (LSP), probably is very abundant throughout the Universe, making up about 25% of its mass. This would easily explain one of the big mysteries in physics, the so-called Dark Matter seen by astronomers from its gravitational effects on stars and galaxies. Our group has pioneered techniques to search directly for dark matter particles in the laboratory and is participating in a new multi-national venture, EURECA. This will build a tonne-sized device using low temperature superconductors to perform a new search. We will contribute to the key aspect of how to shield the experiment from natural background particles, like muons. Another mystery in the Universe are the strange properties of its most abundant particle, the neutrino. This has only recently been found to have a small mass and to readily change form between three different 'flavours' while propagating through space. Details of this are not fully understood but it is known that if properly unravelled it might answer another big question, why there is so little anti-matter in the Universe. We are working on these questions through participation in the big international T2K neutrino beam experiments in Japan. We are building a key component of the detectors and will, within two years, start to analyse the data to unravel these issues. T2K probably will not do a full job, so we have instigated in the UK work on a new neutrino detector concept, based on liquid argon, contributing to the FJNE programme. We plan to build test devices to enable the next generation of neutrino experiments to follow T2K. This is linked also to our work on accelerator technology, MICE, where we are building test beam targets. This is a vital step towards the ultimate facility, a neutrino factory. We are working on key technology for this within the UKNF project. Finally, much of the hardware and computer code developed for these fundamental studies have great relevance well outside our main research. There are many examples, involving projects with a dozen UK companies. For instance, our work with Corus Ltd. on new techniques for neutron detection, has allowed development of new monitors to detect illicit transport of nuclear materials at ports. This will continue now and broaden into medical applications. Our dark matter work has produced a new national facility for underground science, the Boulby laboratory. Here we have started a new project on climate change, SKY, to explore the effect of comic rays on cloud formation.

Taken together the imaging Facilities on the Rutherford Campus will be without equal anywhere in the world. The suite of synchrotron X-ray, neutron, laser, electron, lab. X-ray, and NMR imaging available promises an unprecedented opportunity to obtain information about material structure and behaviour. This infrastructure provides an opportunity to undertake science changing experiments. We need to be able to bring together the insights from different instruments to follow structural evolution under realistic environments and timescales to go beyond static 3D images by radically increasing the dimensionality of information available. This project will use many beamlines at Diamond and ISIS, combining them with laser and electron imaging capability on site, but especially exploiting the 3.3M investment by Manchester into a new imaging beamline at Diamond that will complete in Spring 2012.Traditionally a 3D images are reconstructed from hundreds or thousands of 2D images (projections) taken as the object is rotated. This project will:1) Deliver 3D movies of materials behaviour. 2) Move from essentially black and white images to colour images that reveal the elements inside the material and their chemical state which will be really useful for studying fuel cells and batteries.3) Create multidimensional images by combining more than one method (e.g. lasers and x-rays) to create an image. Each method is sensitive to different aspects.4) Establish an In situ Environments Lab and a Tissue Regeneration lab at the Research Complex. The former so that we can study sample behaviour in real time on the beam line; the latter so that we can study the cell growth and regeneration on new biomaterials. A key capability if we are to develop more effective hard (e.g. artificial hip) and soft tissue (artificial cartilage) replacements.These new methods will provide more detail about a very wide range of behaviours, but we will focus our experiments on materials for Energy and Biomaterials. In the area of energy it will enable us to:Recreate the conditions operating inside a hydrogen fuel cell (1000C) to find out how they degrade in operation leading to better fuel cells for cars and other applicationsStudy the charging and discharging of Li batteries to understand better why their performance degrades over their lifetime.Study thermal barriers that protect turbine blades from the aggressive environments inside an aeroengine to develop more efficient engines.Study the sub-surface corrosion of aircraft alloys and nuclear pressure vessels under realistic conditions improving safetyStudy in 3D how oil is removed from the pores in rocks and how we might more efficiently store harmful CO2in rocks.In the area of biomaterials it will enable us to recreate the conditions under which cells attach to new biomaterials and to follow their attachment and regeneration using a combination of imaging methods (laser, electron and x-ray) leading to:Porous hard tissue replacements (bone analogues) made from bio-active glasses with a microstructure to encourage cell attachmentSoft fibrous tissue replacements for skin, cartilage, tendon. These will involve sub-micron fibres arranged in ropes and mats.Of course the benefits of the multi-dimensional imaging we will establish at Harwell will extend much further. It will provide other academics and industry from across the UK with information across time and lengthscales not currently available. This will have a dramatic effect on our capability to follow behaviour during processing and in service.

Achieving the carbon target for steel and aluminium requires an industry-wide transformation which will result in new business models and new metal flows. The proposal aims to identify credible scenarios for achieving the target, to specify the barriers to achieving them, and to define the economic and policy measures required to drive change. In parallel, the proposal aims to deliver basic technology research that will allow more options for a future materially efficient steel and aluminium economy.It is widely agreed that a cut of at least 60% in global greenhouse gas emissions will be required by 2050 to limit the adverse effects of climate change. Steel and aluminium are responsible for 8% of global energy related emissions. Industry efforts to date have focused on reducing energy in primary production, and recycling metal by melting and re-casting. However, demand for both steel and aluminium is forecast to double, recycling rates are already around 60-70% and the most optimistic projections for energy efficiency improvements deliver only 30% reduction per unit output of material. Efficiency improvements alone are not sufficient, but the 2050 target can be achieved if, in addition to existing measures, energy used in converting ingots to products is halved, the volume of metal used in each application is reduced, and a substantial fraction of metal is re-used without melting. In pursuing this strategy, this proposal is aligned with the EPSRC strategic theme on energy demand reduction.The need for clarity about the physical implications of responding to the carbon target has become a major priority in the metal producing and using industry. Without the work described in this proposal, it is not possible for the government, industry and the public to understand and negotiate the choices they must collectively make in order to meet the carbon target in this sector. Accordingly, this proposal comes with support of 2 million in committed effort from 20 global companies, all with operations in the UK. The business activities of the consortium span primary metal production, conventional recycling, equipment manufacture, road transport, construction, aerospace, packaging and knowledge transfer.The work of the fellowship will be split between business analysis and technology innovation themes. The business analysis theme will identify future scenarios, barriers and a roadmap for meeting the target. This work will include specific analysis of future metal flows, application of a global economic model and the analysis of policy measures. The technology innovation theme aims to optimize the requirements for metal use through novel manufacturing process design, to increase material and energy efficiency in forming and finishing, and to develop solid-state closed-loop recycling for metals. Both themes will be developed in collaboration with the consortium, and will also draw on an international scientific panel and a cross-disciplinary advisory panel in Cambridge.The work will lead to two major reports for wide distribution, direct dissemination into the partner companies, training courses, technology assessments and physical demonstrations of the technology innovations. These will include a demonstration for public engagement. The results of the work on steel and aluminium will be used to stimulate interest among business leaders in other sectors, and will form the basis for a longer term Centre for Low Carbon Materials Processing in Cambridge.The Leadership Fellowship offers a unique and timely opportunity to undertake the basic research required to drive a step-change in material efficiency, by demonstrating that a different flow of metal through the global economy is technically and economically possible, and by inspiring and informing those who can influence change.

This research project addresses the process industry contribution to the UK government goals of tackling climate change and reducing dependence on imported fuel. This programme fills these nationally important objectives by investigating the short, medium and long-term provision of energy for the UK, based on thermal technologies that exploit low grade process heat that is currently not recovered by this industry. The results of this 'Whole Systems Analysis research will improve plant efficiency and displace a significant fraction of fossil fuel use, thus reducing UK carbon dioxide emissions, by using techniques that are secure, clean, affordable and socially welcome. This research involves collaboration between several highly relevant industrial partners (e.g. Corus Ltd, North East Process Industry Cluster (NEPIC) Ltd, EON UK, Veolia (Sheffield Heat & Power Ltd), Pfizer Ltd, etc) and four internationally leading academic centres of excellence (Universities of Sheffield, Newcastle, Manchester & Tyndall Centre). The research programme targets a national problem by exploiting their complementary expertise through Whole Systems Analysis . Thus the objective of this research proposal is to investigate new and appropriate technologies and strategies needed for industry to exploit the large amount of unused low grade heat available. This will be achieved by providing a systematic procedure based on a comprehensive analysis of all aspects of process viability that will enable industry to optimise the management and exploitation of their thermal energy. This detailed procedure will be backed up by a sustained channel of communication between the relevant industrial and academic parties. This multidisciplinary work is thus applicable both to existing plants and the design of future plants. Please note that the establishment of an associated but separately funded EPSRC Network (e.g. PRO-TEM) is considered to be an integral part of this project, in order to satisfy the implicit role of technology transfer in both directions, between the process industry and the wider academic community. It will also provide access to industrial players who will provide essential case studies for the technical and socio-economic work. The case for an associated PRO-TEM Network is briefly discussed herein and the case is presented in detail in a separate proposal by Newcastle University.

The development of new techniques to measure a materials microstructure in conditions where measurement has not been previously possible can lead to a dramatic improvement in the understanding of the material, its processing and hence the ability to control its properties better. At present, the majority of microstructural analysis techniques are destructive and / or require small samples. Consequently, they are limited in applicability if dynamic microstructural analysis in-situ during commercial processing is of interest. A number of techniques have been proposed to directly measure microstructures on-line during processing but as yet no single technique appears to offer a full solution.The metals industry is highly competitive and the ability to adapt to the changing demands of customers is essential, e.g. via introduction of new products. There is also a need to produce high quality (high added value) products in order to keep a competitive edge in the global economy. This in turn requires new and better measurement and control procedures and therefore an on-line inspection system would be highly valuable.The aim of the MAIS project has been to exploit novel multi-frequency electromagnetic techniques to analyse microstructure. The research has involved theoretical analysis of the response to ferrite fraction and morphology and the electromagnetic properties of steel, which has been supported by 3D modelling of both simple and realistic microstructures. In parallel, the problem of inverting the complex inductance spectra acquired by the sensor system to yield parameters of metallurgical significance has been addressed. Finally, sensor configurations which can be deployed on-line have been considered.This follow on project (AMAIS) will demonstrate the efficacy of the electromagnetic microstructure analysis system in a real industrial environment and prove that the technology developed over two previous EPSRC projects in partnership with the metallurgy experts in industry and academia can be taken from the laboratory to real application. The Follow on Fund is also important to ensuring a strong IP position as the technology moves forward.
