The use of advanced ceramics for armour systems allows the defeating of the projectile and ballistic impact energy dissipation providing adequate ballistic protection. The development of lightweight and inexpensive ceramics and armour designs is under ongoing attention by both ceramic armour manufacturers and armour users. This paper summarizes the results of extensive studies of ballistic performance of different armour ceramics, mostly obtained during development, as well as of the materials manufactured by other recognized armour ceramic suppliers, and the designed ceramic-based armour systems. The studied armour ceramics include homogeneous oxide and carbide ceramics and heterogeneous ceramic materials. Ballistic performance of the studied ceramics as function of their structure and properties, armour system design and type of projectile has been discussed. Depending on the requirements for ballistic protection, armour systems may be designed to various configurations and weights based on the most suitable ceramic materials and backing. The examples of successful designs of lightweight armour systems with adequate ballistic performance, including satisfactory multi-hit performance, have been demonstrated. © 2010 Elsevier Ltd and Techna Group S.r.l.

Platinum Metals Review | Year: 2012
The high technical recyclability of platinum group metals means that over 95% recovery can be achieved once pgm-containing scrap reaches a state-of-the-art ref ning facility. Technical challenges exist, but the main barriers to recycling pgms lie in ensuring the collection of scrap and in the capacity and technical capabilities of recycling chains around the world. Economic and legislative drivers are also signif cant. The "seven conditions" for effective recycling and their impact within Europe are discussed in this article; industrial applications are found to lead the way in terms of recycling rates while automotive and particularly electronic areas are currently some way behind. New business models are recommended, to enable precious metal-containing waste to be seen as a valuable resource and ensure the sustainability and security of pgms supply for the future. © 2012 Johnson Matthey.

Multi-junction solar cell technology, based on III-V semiconductor structures grown onto Germanium substrates, is well established as the primary photovoltaic technology used in satellite power generation. As future satellite power requirements will significantly increase due to the adoption of technologies such as electrical propulsion, sensing and telecommunications, next generation space solar cells will be required to significantly increase their conversion efficiency to enable higher energy generation with minimal increase in overall system weight and cost. To this end, this proposal will develop multi-junction space solar cells on high quality, low cost, large area (150mm diameter) Germanium substrates, which will have conversion efficiencies >33% (AM0), utilising novel 4-Junction architectures. The process will adopt dilute nitride epitaxial technology that has been developed by Nanyang Technological University (1). To enable this, a powerful consortium has been assembled, which covers the entire skill set required to produce such cells, including substrate manufacture, advanced epitaxy, device design, device fabrication, test and qualification.

The main objective of the NanoDome project is to develop a robust model-based design and engineering toolkit for the detailed prediction of complex nanomaterial structures produced in a commercially-relevant generic bottom-up Gas-Phase (GP) synthesis process, to improve the control of the nanomaterial production and the industrially-scalable GP synthesis process for more accurate final product properties (e.g. particle size, surface area, structure, chemical composition, morphology and functionalization coatings) and provide potential end-users with a validated tool based on scientific principles that enables predictive design of novel nanomaterials and novel GP production routes thereby shortening their development process. This will be pursued by combining computational modelling, software development and systematic validation activities at lab- and industrial-scale in a three-year project. Existing meso-scale nanomaterial GP synthesis modelling approaches (Lagrangian and stochastic) will be extended and integrated with continuum-scale reactor models to provide a fully functional single discrete mesoscopic model for the evolution of the nanoparticle population inside a control volume as a function of time, together with detailed description of nanoparticle composition and internal structure (e.g. core-shell, multi-layer, radially-dependent composition), particle interaction, coagulation and morphology. Industrial and lab-scale validation will focus on a set of target materials of great impact for the EU, using technologies currently at TRL4-6. The work proposed in the NanoDome project addresses the aforementioned challenges by delivering a modelling and analysis tool for the detailed prediction of complex nanomaterial structures formation in a single-step and industrially scalable GP synthesis process, in order to optimize existing processes, shorten the development of new processes and increase the production rates.
