Nanomaterials research at Ulster into materials including diamond-like carbon (DLC) ultra-thin films, carbon nanotubes (CNT), graphene, silicon and metal oxide nanoparticles has resulted in direct uptake by major industrial manufacturers and led to a directly quantifiable socio-economic impact via added value, improved efficiencies and cost-savings and has secured or increased the employment of skilled engineering staff. Examples of this impact since 2008 include ceramic nanoparticles research in partnership with AVX Ltd that resulted in improved production efficiency processes (up 20%) and higher quality devices (up 10%). [text removed for publication] Research into ultra-thin DLC films, funded by Seagate, has led to their incorporation into magnetic media. [text removed for publication] Our nanoparticle research has attracted a new spin-in company SiSaf Ltd. (2009) and by incorporating NIBEC's expertise in nanomaterials into its business plan, the company was able to grow to a valuation of £3.5m and employ 7 people in skilled technical positions.
Innovative deposition equipment manufactured by AIXTRON Nanoinstruments, a company created to exploit research outputs of the University of Cambridge Department of Engineering, is used around the world to grow carbon nanotubes and graphene. These materials are subject to intensive efforts to refine and commercially exploit their unique properties. AIXTRON Nanoinstruments is based in the UK and has produced almost 100 products, the majority of which were after 2008 and sold to customers internationally. Products range in price from GBP80k to GBP1.5M. [text removed for publication]
The Thin Film Centre (TFC) group at UWS pioneered thin film materials and processes for plastic electronics with Dupont Teijin Films (DTF) Ltd and Plastic Logic (PL) Ltd over a period of nine years. This work was pivotal to the growth of PL from a start-up position resulting in the first all-polymer e-book reader and was the basis of a world leading position in the supply of specialised substrates for DTF Ltd.
Researchers in QUB developed the first commercial process control system (Rotolog) and simulation software (RotoSim) for the Rotomoulding Plastics Industry. There has also been recent commercialisation of a new energy-saving system, the Rotocooler.
The fundamental understanding of the process that was developed also enabled the moulding of new materials for new application areas, notably motorcycle fuel tanks (now used by BMW, Ducati, Harley Davidson and Honda) and the world's first concept car made from sustainable polymers.
Global economic and environmental impact arises from a significantly more efficient process, better product quality, a greater selection of processable materials and thus increased sales.
Research in atmospheric pressure (thermal) chemical vapour deposition (APCVD) at the University of Salford demonstrates the following impact:
A manufacturing process developed by Bradford researchers has revolutionised the way endodontists perform root canal treatments. When coated with a hydrophilic polymer, the highly-filled hygroscopic material has enabled UK company DRFP to develop SmartPoint — a new endodontic technique that dramatically reduces failure rates of root canal treatments from 11-30% over five years to approximately 1%, and gives lower levels of post-operative pain when compared with conventional techniques. The technology has won three awards for innovation and DRFP has expanded significantly, with a dedicated production facility and sales team offering visits to dentists to demonstrate the benefits of the technology.
Diffusion bonding (DB) is well-known for producing structured materials with fine scale features and is a critical technology for high efficiency reactors, e.g. heat exchangers and fuel cells, but currently equipment is slow and expensive (and there are size limitations to the `assemblies' that can be built). The University has researched and developed, with industry partners, a rapid affordable diffusion bonding (ADB) process involving direct heating to provide appropriate temperature and stress states and utilising flexible ultra-insulation (vacuum) for pressing titanium (and now aluminium) sheets together. The process operates at low stresses thus avoiding `channel' collapse. Investment is taking place in the partner companies to exploit the technology. A breakthrough has been achieved in the chemical machining of three dimensional structures for laminar flow technology assemblies in aluminium and titanium, that can be built by ADB.
Viewing carbon nanotubes (CNTs) as very rigid polymer molecules led to research on turning them into useful materials. Strategic investments to develop different aspects of this research have been made by two separate companies. A process for the synthesis of CNTs was transferred to Thomas Swan Ltd who have made significant investment, and are now Europe's leading supplier of high-quality CNTs. In 2003 a process was invented to spin CNT fibres directly from a synthesis reactor. The process is intrinsically cheaper than the conventional process for carbon fibre and it produces a tougher and more versatile product. The University of Cambridge (UCAM) spin-out company Q-Flo Ltd (created in 2004 to achieve focus on transfer of this technology) and Plasan (multinational manufacturer of vehicle defensive armour) formed a joint venture in 2010 which has enabled the first-stage scale-up of manufacture.
Research on vapour growth of semiconductor compounds led to a key breakthrough in growing large crystals which form the basis for sensitive X-and gamma-ray detectors. The process was commercialised by a Durham University spin-out company, Kromek Ltd., which floated on AIM at £55M and has over 100 employees in the UK and USA. The X-ray detectors are in use in Kromek's security systems for screening liquids at airports, significantly reducing restrictions on duty free goods. This application won the $400,000 international prize in the 2009 Global Security Challenge. The company also markets gamma-ray detectors for nuclear isotope identification. These have won contracts totalling $7.5M from the US Defense Threat Reduction Agency and are in use at Fukushima.
Nanoforce Technology Ltd. is a spin-out company wholly owned by QMUL, active in the field of polymeric and ceramic materials. Bridging the gap between academic research and industrial applications, Nanoforce has done business with over 100 companies since 2008, providing the key research expertise and specialist facilities to enable the development of new materials and commercial products, including Sugru® a room temperature vulcanizing silicone rubber, Zelfo® a self-binding cellulose material, and BiotexTM a range of high-performance yarns, fabrics and pre- consolidated sheets based renewable resources such as PLA and natural flax fibres. Nanoforce has been promoting the development and commercialisation of spark plasma sintering (SPS) since 2006, which resulted in Kennametal recently opening the first commercial SPS facility in the UK to produce advanced ceramic armour. Nanoforce's clients have included large multi-nationals such as DSM, Dow Chemical, General Electric, SABIC, L'Oreal, Shell, Sibelco, governmental agencies such as Defence Science and Technology Laboratory (Dstl), and a large number of SME's.
