Chemical separations are critical to almost every aspect of our daily lives, from the energy we use to the medications we take, but consume 10-15% of the total energy used in the world. It has been estimated that highly selective membranes could make these separations 10-times more energy efficient and save 100 million tonnes/year of carbon dioxide emissions and £3.5 billion in energy costs annually (US DoE). More selective separation processes are essential to "maximise the advantages for UK industry from the global shift to clean growth", and will assist the move towards "low carbon technologies and the efficient use of resources" (HM Govt Clean Growth Strategy, 2017). In the healthcare sector there is growing concern over the cost of the latest pharmaceuticals, which are often biologicals, with an unmet need for highly selective separation of product-related impurities such as active from inactive viruses (HM Govt Industrial Strategy 2017). In the water sector, the challenges lie in the removal of ions and small molecules at very low concentrations, so-called micropollutants (Cave Review, 2008). Those developing sustainable approaches to chemicals manufacture require novel separation approaches to remove small amounts of potent inhibitors during feedstock preparation. Manufacturers of high-value products would benefit from higher recovery offered by more selective membranes. In all these instances, higher selectivity separation processes will provide a step-change in productivity, a critical need for the UK economy, as highlighted in the UK Government's Industrial Strategy and by our industrial partners. SynHiSel's vision is to create the high selectivity membranes needed to enable the adoption of a novel generation of emerging high-value/high-efficiency processes. Our ambition is to change the way the global community perceives performance, with a primary focus on improved selectivity and its process benefits - while maintaining gains already made in permeance and longevity.

This proposal will deliver novel, integrated methodologies for the design and scalable manufacture of next generation resorbable polymer nanocomposites, linking the science and engineering principles which underpin successful processing of such materials. This will enable new smart health-care materials in applications from bone fracture fixation to drug delivery. The methodologies will be optimised on a system comprising novel nanoparticles, selected blends of medical-grade degradable polymer and specifically designed molecular dispersants. Optimised methodologies will be applied at scale on industrial equipment to produce demonstrator resorbable implants with specific structural attributes and degradation timescales. Wider applications include degradable food packaging and products requiring end-of-life disposal.

Heating and cooling are essential to our lives. We rely on them for comfort in our homes and vehicles, and businesses need heating and cooling for productive workplaces and industrial processes. Taken together, space and process heating and cooling represent the biggest contribution to the UK's energy consumption, and the biggest source of greenhouse gas emissions. Heating is primarily provided from burning natural gas, whereas cooling is primarily provided from compressing volatile fluorinated gases. However, these conventional technologies are neither efficient, not friendly to the environment. Barocaloric effects are reversible thermal changes that occur in mechanically responsive solids when subjected to changes in pressure. These effects are analogous to the pressure-induced thermal changes in gases that are exploited in current heat pumps, but they promise higher energy efficiencies and obviate the need for harmful greenhouse gases. We aim at developing an energy-efficient barocaloric heat pump based on novel barocaloric hybrid composite materials that combine the best properties of organic barocaloric materials, namely extremely large pressure-driven thermal changes, and the best of inorganic barocaloric materials, namely high thermal conductivity and low hysteresis. A technological transformation of this magnitude will require the development of bespoke economic and policy strategies for its successful deployment. Therefore, we aim at developing a fully integrated bespoke economic and policy strategy that will support the innovation of BC heat pumps through to commercialisation. The achievement of heat pumps that operate using barocaloric materials instead of gases will permit decarbonising heating and cooling, provide energy independence, and enable the UK to become the world leader on this emerging technology.

The UK government recognises that 'our economy is driven by high levels of skills and creativity' and has prioritised investment in skills as a means to recovery rapidly from the current economic downturn (HM Government: New Industry, New Jobs, 2009). Bioprocessing skills underpin the controlled culture of cells and microorganisms and the design of safe, environmentally friendly and cost-effective bio-manufacturing processes. Such skills are generic and are increasingly being applied in the chemical, pharmaceutical and regenerative medicine sectors. Recent reports, however, highlight specific skills shortages that constrain the UK's capacity to capitalise on opportunities for wealth and job creation in these areas. They emphasise the need for bioprocessing skills related to the application of 'mathematical skills... to biological sciences', in core bioprocess operations such as 'fermentation' and 'downstream processing' and, for many engineering graduates 'inadequate practical experience'. UK companies have reported specific problems in 'finding creative people to work in fermentation and downstream processing' (ABPI: Sustaining the Skills Pipeline, 2005 & 2008) and in finding individuals capable of addressing 'challenges that arise with scaling-up production using biological materials' (Industrial Biotechnology Innovation and Growth Team report: Maximising UK Opportunities from Industrial Biotechnology, 2009). Bioprocessing skills are also scarce internationally. Many UK companies have noted 'the difficulties experienced in recruiting post-graduates and graduates conversant with bioprocessing skills is widespread and is further exaggerated by the pull from overseas (Bioscience Innovation and Growth Team report: Bioscience 2015, 2003 & 2009 update). The EPSRC Industrial Doctorate Centre (IDC) in Bioprocess Engineering Leadership has a successful track record of equipping graduate scientists and engineers with the bioprocessing skills needed by UK industry. It will deliver a 'whole bioprocess' training theme based around fermentation and downstream processing skills which will benefit from access to a superbly equipped £25M bioprocess pilot plant. The programme is designed to accelerate graduates into doctoral research and to build a multidisciplinary research cohort. Many of the advanced bioprocessing modules will be delivered via our MBI Training Programme which benefits from input by some 70 industry experts annually (www.ucl.ac.uk/biochemeng/industry/mbi). Research projects will be carried out in collaboration with many of the leading UK chemical and pharmaceutical companies. The IDC will also play an important role supporting research activities within biotechnology-based small to medium size enterprises (SMEs). The need for the IDC is evidenced by the fact that the vast majority of EngD graduates progress to relevant bioindustry careers upon graduation. This proposal will enable the IDC to train the next generation of bioindustry leaders capable of exploiting rapid progress in the underpinning biological sciences. Advances in Synthetic Biology in particular now enable the rational design of biological systems to utilise sustainable sources of raw materials and for improved manufacturing efficiency. These will lead to benefits in the production of chemicals and biofuels, in the synthesis of chemical and biological pharmaceuticals and in the culture of cells for therapy. The next generation of IDC graduates will also possess a better understand of the global context in which UK companies must now operate. This will be achieved by providing each EngD researcher with international placement opportunities and new training pathways either in bioprocess enterprise and innovation or in manufacturing excellence. In this way we will provide the best UK science and engineering graduates with internationally leading research and training opportunities and so contribute to the future success of the UK bioprocess industries.

Membranes offer exciting opportunities for more efficient, lower energy, more sustainable separations and even entirely new process options - and so are a valuable tool in an energy constrained world. However, high performance polymeric, inorganic and ceramic membranes all suffer from problems with decay in performance over time, through either membrane ageing (membrane material relaxation) and/or fouling (foreign material build-up in and/or on the membrane), and this seriously limits their impact. Our vision is to create membranes which do not suffer from ageing or fouling, and for which separation functionality is therefore maintained over time. We will achieve this through a combination of the synthesis of new membrane materials and fabrication of novel membrane composites (polymeric, ceramic and hybrids), supported by new characterisation techniques. Our ambition is to change the way the global membrane community perceives performance. Through the demonstration of membranes with immortal performance, we seek to shift attention away from a race to achieve ever higher initial permeability, to creation of membranes with long-term stable performance which are successful in industrial application.
