The new high productive platform for 3D main objective of NANOMICRO project is to provide the manufacturing industry with an entirely nanomicromanufacturing platform, by way of a new micron scale resolution and an innovative direct parallel-deposition process. The process will be able to deliver a layer wise manufacturing approach using highly focalized powder/heat fluxes, with dimensions in the micron range. This will allow to control spatial resolution within the same limit and building up parts with such extreme control of the (fully dense) bulk materials. The S/T objectives of the project will provide: -several submicron powder grades as aggregates of nanocrystals; -implementation of highly localized powder fluxes to drive high accuracy object fabrication, on the scale of better than 5 m; -online monitoring allowing combinations of accuracy and productivity to be achieved at which the technology will become a new production tool, for 3D metal parts integrating nanostructures; -High-precision and High-production (HP2) micro-manufacturing deposition strategies; -multimaterial (gradient) deposition using different powder types on the same layer; -integrated materials and component ecodesign; -nano(micro)manufacturing principles by allowing integration of nanoscale structures first at powder level (micron agglomerates) and then at 3D part level (mm); -HP2 microfabrication station capable of enhanced accuracy and faster micro-objects deposition (typically 1x1 mm/each) by using single laser sintering head or microwave parallelized multi- sintering heads; -Make the developed machine available for exploitation primarily within the EU manufacturing industry. NANOMICRO project fully responds to the call topic extending the microfabrication process capabilities by encompassing a wider range of innovative materials and geometric shapes, satisfying functional and technical requirements, allowing the emerging of new microproducts in many technological fields.

Fuel Systems (FS) are critical for aircraft safety. Fire, ice and system failures are typical safety hazards associated to FS. FS accidents, though only representing 2% of accidents/incidents, continue to be a recurrent concern, especially as: the complexity of FS escalades to cope with increasing needs, including more stringent safety requirements ; flight conditions evolve with new routes at high altitude, crossing the Arctic, and faster climbing and approach; climate changes with more aircraft (A/C) exposed to hazardous weather. Thus, FS have to deal with more extreme temperatures, stronger temperature gradients, more humidity, and more exposure to lightning. In addition, new technologies are emerging: Composite, More Electric and Alternative Fuel, bringing new safety requirements. For example, within the composite A/C environment, systems will be more exposed to lightning and induced arcing. SAFUEL will address the urgent need for European-led research in FS safety to develop the next generation of safer FS also offering the opportunity to reduce the current over-dependence on patented US technology. SAFUEL will develop: -the new FS design, meeting the severe safety constraints of Composite and More-Electric A/C and evolving flight conditions -a range of highly innovative prototypes, adequate testing and simulation tools to allow regulators to assess the safety of future FS as well as providing the necessary data to support authorities in rules and regulations for safe flight in icing conditions. The project will also significantly improve the compliancy of the FS with evolving flight conditions and emerging technologies, enabling perfect emergence of Composite A/C. By achieving these objectives, SAFUEL will reduce the rate of accidents/incidents related to FS from the current 2% to 0.4% instead of witnessing an increase. SAFUEL brings together a consortium of best-of-breed experts from academia and industry-from components to airframer. It will last 3 years.

No aerosol system on the market is perfectly suited for aerosol therapy in infants. The RESPIRE project aims to answer this need by developing an innovative piezoelectric microperforated vibrating membrane nebulizer, the Baby Nimbus™; efficient, fast, portable and silent. Consisting of three complementary partners, the project was divided into three phases: technology development by the company Télémaq (Sophia Antipolis), in vitro and in vivo test performed on baboons by Inserm U618 (Tours), clinical trials in infants led by AP-HM (Marseille). Studies conducted by Inserm U618 and AP-HM focused on the influence of particle size on lung deposition in baboons and the clinical score in infants. Three devices of different droplet sizes were compared in the in vivo study, the Pari LC Sprint SP® (Pari, Germany, MMAD 4.5μm - flow 0.18 mL/min), the E-Flow Rapid® (Pari, Germany, MMAD 4.8μm - flow 0.35 mL/min) and Baby Nimbus™ (Télémaq, France). Four versions of Baby Nimbus™ were needed to achieve the MMAD of 2.4 μm and flowrate of 0.4 mL/min (Spraytec ®, Malvern, England). Preliminary in vivo results show that the amount of the initial charge deposited in the lungs is 0.9% for the Pari LC Sprint SP®, 1.2% for E-Flow Rapid® and 2.2% for the Baby Nimbus™. Additional in vivo tests and clinical trials are under way to rule definitively on the efficiency provided by the Baby Nimbus™. © 2012 Elsevier Masson SAS. All rights reserved.
