'Watching paint dry' is a metaphor for a boring and pointless activity. In reality, the drying of liquids is a complex process and the imperturbable appearance to the eye can hide a wealth of dynamics occurring inside the liquid. The effect of these internal processes is to change the distribution of materials in the deposit left after drying. We are all familiar with the coffee-ring effect, where split coffee dries to form a ring of solids at the edge of the spill - of little use if you are trying to coat a surface uniformly. This project is all about the drying of droplets, either in air or on a surface; one isolated droplet, two droplets merging or many droplets in a spray. We seek to understand how drops dry and how to control where the particles or molecules in the drop end up after the drop evaporates. When do you get a solid particle or a hollow particle? A round one or a spiky one? A uniform particle or one with shells? Or on a surface: a coffee-ring or a pancake? A uniform deposit, a layered one or a bull's eye? Are particles crystalline or amorphous, are different components mixed or separated? There are a myriad of possibilities for controlling the microstructure and properties of the final particle or film. Drying is complicated for three main reasons. First, many transport processes (evaporation, heat flow, diffusion, convection) occur simultaneously and are strongly coupled. For example, in a small droplet of alcohol and water evaporating on a surface, the liquid inside the drop will flow around in a doughnut pattern tens of times each second. Second, the conditions in a drying droplet are often far from equilibrium. For example, a small water droplet in air or on a smooth clean surface can be cooled to -35 degrees C without freezing. So to understand drying one needs to understand the properties of fluids far from equilibrium. It is generally not possible to predict the final outcome of drying from the properties of simple solutions near equilibrium. Third, drops do not dry in isolation. They may merge or bounce, coalesce or chase each other across a surface. The evaporation of one droplet affects its neighbours. Moving droplets change the flow of air around other droplets, coupling the motion of droplets. Why does anyone care, beyond the intellectual fascination with the bizarre outcomes of droplet drying? Drying of droplets turns out to be a rather important process in practical applications: spray painting, graphics printing, inkjet manufacturing, crop spraying, coating of seeds or tablets, spray cooling, spray drying (widely used in food, pharmaceutical and personal care products), drug inhalers and disinfection, to give a few examples. The physics and chemistry underlying all these applications is the same, but if manifests itself in different ways and the desired outcome varies between applications. The first challenge addressed by this project is one of measurement: how do you work out what is going on in a droplet that is less than a tenth of a millimetre across and may dry in less than a second? We have already developed sophisticated measurement tools but will need to extend these further. Another challenge is one of modelling: to understand the drying process we need a theoretical framework and computer models to explain - and predict - experimental observations. We will begin looking at the fundamental processes occurring in single drops in air and on a surface and then explore what happens when drops interact or coalesce. This fundamental understanding will be fed into improved models of arrays, clouds or sprays of droplets that are encountered in most practical applications (such as spray coating, spray drying, inhalers or inkjet manufacturing). We will use an Industry Club to engage with companies from a range of different sectors. This Club will provide a forum for sharing problems, ideas and solutions and for disseminating the knowledge generated in the project.

The proposed EPSRC CDT in the Science and Applications of Graphene and Related Nanomaterials will respond to the UK need to train specialists with the skills to manipulate new strictly two-dimensional (2D) materials, in particular graphene, and work effectively across the necessary interdisciplinary boundaries. Graphene has been dubbed a miracle material due to the unique combination of superior electronic, mechanical, optical, chemical and biocompatible properties suitable for a large number of realistic applications. The potential of other 2D materials (e.g. boron nitride, transition metal and gallium dichalcogenides) has become clear more recently and already led to developing 'materials on demand'. The proposed CDT will build on the world-leading research in graphene and other 2D nanomaterials at the Universities of Manchester (UoM) and Lancaster (LU). In the last few years this research has undergone huge expansion from fundamental physics into chemistry, materials science, characterization, engineering, and life sciences. The importance of developing graphene-based technology has been recognized by recent large-scale investments from UK and European governments, including the establishment of the National Graphene Institute (NGI) at UoM and the award of 'Graphene Flagship' funding by the European Commission within the framework of the Future and Emerging Technologies (Euro1 billion over the next 10 years), aiming to support UK and European industries.Tailored training of young researchers in these areas has now become urgent as numerous companies and spin-offs specializing in electronics, energy storage, composites, sensors, displays, packaging and separation techniques have joined the race and are investing heavily in development of graphene-based technologies. Given these developments, it is of national importance that we establish a CDT that will train the next generation of scientists and engineers who will able to realise the huge potential of graphene and related 2D materials, driving innovation in the UK, Europe and beyond. The CDT will work with industrial partners to translate the results of academic research into real-world applications in the framework of the NGI and support the highly successful research base at UoM and LU. The new CDT will build directly on the structures and training framework developed for the highly successful North-West Nanoscience DTC (NOWNANO). The central achievement of NOWNANO has been creating a wide ranging interdisciplinary PhD programme, educating a new type of specialist capable of thinking and working across traditional discipline boundaries. The close involvement of the medical/life sciences with the physical sciences was another prominent and successful feature of NOWNANO and one we will continue in the new CDT. In addition to interdisciplinarity, an important feature of the new CDT will be the engagement with a broad network of users in industry and society, nationally and internationally. The students will start their 4-year PhD with a rigorous, bespoke 6-month programme of taught and assessed courses covering a broad range of nanoscience and nanotechnology, extending beyond graphene to other nanomaterials and their applications. This will be followed by challenging, interdisciplinary research projects and a programme of CDT-wide events (annual conferences, regular seminars, training in transferable skills, commercialization training, outreach activities). International experience will be provided by visiting academics and secondments to overseas partners. Training in knowledge transfer will be a prominent feature of the proposed programme, including a bespoke course 'Innovation and Commercialisation of Research' to which our many industrial partners will contribute, and industrial experience in the form of 3 to 6 months secondments that each CDT student will undertake in the course of their PhD.

The ABC will be one of two hubs funded through the Transforming Construction Industrial Challenge. ABC aims to: 'revolutionise the way the UK designs, constructs and operates buildings by realising the potential for the integration of advanced offsite manufacturing with state of the art digital design. This will include the incorporation and integration of energy generation, storage, and release technologies to create Active Buildings which substantially reduce both the operational costs of buildings and their demand on the UK energy infrastructure'. Our Vision is to enable energy resilient communities that are powered by the sun, share energy with transport and other buildings, whilst realising value for the UK by overcoming barriers and developing new business models with global potential. The Mission - ABC is a national centre of excellence and will catalyse a revolution in smart buildings and energy sharing. ABC will bring together energy, construction, government and research to create a dynamic ecosystem that identifies barriers and creates solutions for scale up and deployment of buildings and communities that are Active. ABC will prove scale, enable an industry and create the conditions for market adoption. Critical to this will be clustered demonstration facilities on a variety of building typologies and pipeline of several thousand buildings which are being considered by a diverse array of assembled supporting companies and organisations. We have already demonstrated that we can use buildings that are manufactured using the principles of car making to rapidly construct facilities that have facades that generate heat and electricity from the sun and include elements and new materials that store this energy (both electricity and heat) until we need it. Critically this enables buildings to be powered (electrically) and heated without any gas connection. In addition, our initial demonstrations have shown that the buildings can generate allot more energy than they use. Our 'Active Classroom' has generated over 1.6 times the energy used in its first full year and putting that in perspective the spare power would have driven one of our EVs for over 26,500 miles. Our aim then is to transform the way we think of buildings as consumers of power and requiring more infrastructure the more we build to a solution both to the requirements of occupancy and energy decarbonisation. One million homes would in essence require one large nuclear powerplant, however adoption of the new Active concept essentially delivers the homes and the powerplant at the same time. This is vitally important as we transition to electric cars which will be a major element of where excess power from buildings can be fed and with advanced new communication systems the fact that a car is stationary and by a building for almost 95% of its life we have potential for a huge mobile storage reserve. Construction also creates positive economic conditions. To frame the opportunity in relation to Active Homes, in a recent report by the UK Housebuilders Federation, the economic case for increasing home building is compelling. Each additional 10,000 units would support 43,000 jobs, increase economic output by £1.36bn, lead to £120m in tax recovery, £43.2m in local infrastructure and an increase in local economic spending by £320m. 10,000 Active homes would also add renewable energy capacity of ca 50MW including storage via EVs, thermal stores and internal batteries. Clearly this is only part of the story since there will also be tremendous value from non-residential buildings that will be showcased for education, factory and commercial properties as part of the delivery programme for ABC and these in many cases can form energy hubs for existing communities of more traditional buildings.

The Transforming the Foundation Industries Challenge has set out the background of the six foundation industries; cement, ceramics, chemicals, glass, metals and paper, which produce 28 Mt pa (75% of all materials in our economy) with a value of £52Bn but also create 10% of UK CO2 emissions. These materials industries are the root of all supply chains providing fundamental products into the industrial sector, often in vertically-integrated fashion. They have a number of common factors: they are water, resource and energy-intensive, often needing high temperature processing; they share processes such as grinding, heating and cooling; they produce high-volume, often pernicious waste streams, including heat; and they have low profit margins, making them vulnerable to energy cost changes and to foreign competition. Our Vision is to build a proactive, multidisciplinary research and practice driven Research and Innovation Hub that optimises the flows of all resources within and between the FIs. The Hub will work with communities where the industries are located to assist the UK in achieving its Net Zero 2050 targets, and transform these industries into modern manufactories which are non-polluting, resource efficient and attractive places to be employed. TransFIRe is a consortium of 20 investigators from 12 institutions, 49 companies and 14 NGO and government organisations related to the sectors, with expertise across the FIs as well as energy mapping, life cycle and sustainability, industrial symbiosis, computer science, AI and digital manufacturing, management, social science and technology transfer. TransFIRe will initially focus on three major challenges: 1 Transferring best practice - applying "Gentani": Across the FIs there are many processes that are similar, e.g. comminution, granulation, drying, cooling, heat exchange, materials transportation and handling. Using the philosophy Gentani (minimum resource needed to carry out a process) this research would benchmark and identify best practices considering resource efficiencies (energy, water etc.) and environmental impacts (dust, emissions etc.) across sectors and share information horizontally. 2 Where there's muck there's brass - creating new materials and process opportunities. Key to the transformation of our Foundation Industries will be development of smart, new materials and processes that enable cheaper, lower-energy and lower-carbon products. Through supporting a combination of fundamental research and focused technology development, the Hub will directly address these needs. For example, all sectors have material waste streams that could be used as raw materials for other sectors in the industrial landscape with little or no further processing. There is great potential to add more value by "upcycling" waste by further processes to develop new materials and alternative by-products from innovative processing technologies with less environmental impact. This requires novel industrial symbioses and relationships, sustainable and circular business models and governance arrangements. 3 Working with communities - co-development of new business and social enterprises. Large volumes of warm air and water are produced across the sectors, providing opportunities for low grade energy capture. Collaboratively with communities around FIs, we will identify the potential for co-located initiatives (district heating, market gardening etc.). This research will highlight issues of equality, diversity and inclusiveness, investigating the potential from societal, environmental, technical, business and governance perspectives. Added value to the project comes from the £3.5 M in-kind support of materials and equipment and use of manufacturing sites for real-life testing as well as a number of linked and aligned PhDs/EngDs from HEIs and partners This in-kind support will offer even greater return on investment and strongly embed the findings and operationalise them within the sector.

This project is both multi-scale and multi-disciplinary, and spans research areas across physics, mechanical engineering, computer science and chemical engineering. Our aim is to produce, for the first time, a general, robust and efficient open-source code for the simulation of non-continuum flows for engineering applications. Such flows are vital to the performance of a number of potentially transformative future technologies (e.g., highly-efficient sea-water desalination using membranes of carbon nanotubes, and nano-structured hydrophobic surfaces for marine drag reduction) but they cannot be simulated using conventional continuum-fluid simulations. Our work exploits the core methodological advances emerging from the EPSRC Programme Grant "Non-equilibrium Fluid Dynamics for Micro/Nano Engineering Systems" (EP/I011927/1), which have demonstrated exciting potential in the multi-scale modelling of non-continuum flows using hybrid continuum-particle methods. The software developed in this project builds on the already widely-adopted open-source code OpenFOAM for computational fluid dynamics. In capitalising on a) the success of the UK's OpenFOAM software and b) the EPSRC's Programme Grant investment in a strategic research area, this project aims to bring sustainability to both.
