Biosensor development is a very promising and prospective field of research in food- clinical- and environmental analysis. Besides conventional analytical methods biosensors specifically detect only some decisive components. However, miniaturised sensor systems are able to detect components in the femto/ato-gramm region with almost no interference to other components in the investigated system. The advantage of such technologies is beside the high sensitivity/selectivity, the cost reduction and the very fast response of such analytic systems. Complex sensor systems will be developed for multiple parameter sensing on real samples combined with signal enhancement strategies. The network created by SAMOSS will improve the further development of biosensors in combination with optochemical sensing techniques in the fields of application and by broader distribution of knowledge. The main topics of the development will comprise the research and development of new materials for optochemical sensing and microfluidic applications, microfluidic sample handling modules, multifunctional elements, signal enhancement and innovative detection systems. SAMOSS will create a European Centre of Excellence for training young researchers in Biosensor Research and Development suited for Applications in Medicine, Food and Beverage Technologies as well as Environmental issues. Through well trained researchers SAMOSS will provide widely skilled personnel for a) the European Biosensor Research in Academia and b) the European Biosensor Industry. As a European Centre of Excellence SAMOSS will deliver a flexible and adaptable network of young researchers that is capable to accomplish the European needs in research and development of new, innovative biosensors for food and beverage analysis, environmental analysis and health care. Thus they will be well trained to become future team leaders in these research and development fields, whether in the domain of academia or in the private sector.

The objective of this 4-year project is to provide the analytical basis for a socio-ecological transition in Europe: the change to a new growth path with smart, sustainable and inclusive growth as is envisaged in the EU 2020 strategy. In order to support the transition, we analyse the need, the feasibility and best practice for change, specifying the institutional changes needed at all policy levels to implement these options. The old and new challenges Europe is facing define the starting point: globalisation, new technologies and postindustrialisation, demographic change and ecology in the context of welfare systems that have come under stress due to high public deficits. The vision is that Europe will become a role model for a high road growth path which actively incorporates social and ecological goals, employment, gender and cultural aspects in an ambitious, forward looking way while continuing to be competitive in a globalised world. To achieve these objectives, the consortium will carry out and synthesise robust research in research areas covering the challenges to the welfare system, the biophysical dimension of socio-economic development, the identification of drivers towards socio-ecological transition, the role of governance and institutions on the European as well as the regional level. The consortium will benefit from ongoing dialogue with international experts in the form of expert panels and sounding boards, taking into account their views on the direction and feasibility for this new growth path. The project will be carried out by a consortium of 34 partners from universities and research institutes with international and interdisciplinary expertise. It represents 12 member states. High level Scientific and Policy Boards will monitor the analysis and the policy conclusions to guarantee the impact and dissemination of the results.

In a series of two contributions, decisive business-related aspects of the current process status to transfer research results on diffractive optical elements (DOEs) into commercial solutions are discussed. In part I, the focus was on the patent landscape. Here, in part II, market estimations concerning DOEs for selected applications are presented, comprising classical spectroscopic gratings, security features on banknotes, DOEs for high-end applications, e.g., for the semiconductor manufacturing market and diffractive intra-ocular lenses. The derived market sizes are referred to the optical elements, itself, rather than to the enabled instruments. The estimated market volumes are mainly addressed to scientifically and technologically oriented optical engineers to serve as a rough classification of the commercial dimensions of DOEs in the different market segments and do not claim to be exhaustive. © 2014 Thoss Media and De Gruyter.

Nanocrystalline Mn-Zn ferrite powders were synthesized by thermal decomposition of an oxalate precursor. Two polymorphs of a mixed Mn-Zn-Fe oxalate dihydrate were obtained by precipitation of metal ions with oxalic acid: monoclinic α-(Mn, Zn, Fe)3(C2O4) 3·6H2O is obtained after precipitation and ageing at 90 °C, whereas the orthorhombic β-type is formed after precipitation at room temperature. The morphology of the oxalate crystals can be controlled by the precipitation conditions. The α-polymorph of the mixed oxalate consists of prismatic and agglomerated particles. The β-oxalate forms non-agglomerated crystallites of submicron size. Thermal decomposition of the oxalate at 350 °C in air results in an amorphous product. Nanosize Mn-Zn ferrite powders are formed at 500 °C and a mixture of haematite and spinel is observed at 750 °C. The thermal decomposition of the mixed oxalate is monitored by thermal analysis, XRD and IR-spectroscopy. The morphology of the oxalate particles is preserved during thermal decomposition; the oxide particle aggregates display similar size and shape as the oxalates. The primary particles are much smaller; their size increases from 3 nm to 50 nm after decomposition of the oxalates at 350 and 500 °C, respectively. The powder synthesized by decomposition at 500 °C was sintered at 1150 °C to dense and fine-grained Mn-Zn ferrites. © 2010 Elsevier Ltd and Techna Group S.r.l.

Nanocrystalline Ni-Cu-Zn ferrite powders Ni 0.20Cu 0.20Zn 0.62Fe 1.98O 3.99 were prepared by thermal decomposition of an oxalate precursor. The particle size is 6nm and 350nm, respectively, for powders obtained through calcinations at 350°C or 750°C. The shrinkage behavior significantly changes with particle size; the temperature of maximum shrinkage rate is T MSR=700°C for particles of 6nm size and increases to T MSR=880°C for particles 350nm in size. Dense samples with a permeability of μ=780 are obtained by sintering at 900°C for 2h. Mixtures of nanocrystalline and sub-micron powders allow tailoring of the shrinkage behavior. A maximum permeability of μ=840 is obtained after sintering of a 1:1-mixture at 900°C. This demonstrates the potential of nanocrystalline ferrites for co-firing without additives at 900°C and integration of ferrite inductors into LTCC modules. © 2011 Elsevier Ltd.

We have studied sub-stoichiometric NiCuZn ferrites with iron deficiency (i.e., <50mol% Fe2O3) of composition Ni 0.20Cu0.20Zn0.60zFe2-zO 4-(z/2) with 0≤z≤0.06. The temperature of maximum shrinkage rate is shifted from T=1000 °C for z=0 towards lower temperatures down to T=900 °C for a sub-stoichiometric ferrite with z=0.02. Dense samples are obtained after firing at 900 °C for z>0 only. Sub-stoichiometric compositions (z>0) do not form single-phase spinel ferrites after sintering at 900 °C, but rather represent mixtures of CuO and a stoichiometric ferrite with slightly modified composition. The formation of small amounts of CuO at grain boundaries is demonstrated by XRD and SEM. The permeability is increased from μ=80 for stoichiometric ferrites (z=0) to μ=660 for z=0.02. The formation of CuO during sintering of sub-stoichiometric ferrites supports densification and is a prerequisite for low temperature firing of multilayer inductors. Addition of 1 wt% Bi2O3 as liquid phase sintering aid is required to provide sufficient densification of the stoichiometric ferrite (z=0) at 900 °C. Addition of 0.37 wt% Bi 2O3 to a sub-stoichiometric ferrite (z=0.02) results in dense samples after firing at 900 °C; however, the microstructure formation is dominated by heterogeneous grain growth. © 2011 Elsevier B.V.

Y-type polycrystalline hexagonal ferrites Ba 2Co 2-x-yZn xCu yFe 12O 22 with 0≤x≤2 and 0≤y≤0.8 were prepared by the mixed-oxide route. Single phase Y-type ferrite powders were obtained after calcinations at 1000 °C. Samples sintered at 1200 °C show a permeability that increases with the substitution of Zn for Co and display maximum permeability of μ′=35 at 1 MHz for x=1.6 and y=0.4. A resonance frequency f r=500 MHz is observed for Zn-rich ferrites with y=0 and 0.4. The saturation magnetization increases with substitution of Zn for Co. Addition of Bi 2O 3 shifts the temperature of maximum shrinkage down to T≤950 °C. Moreover, an increase of the Cu-concentration further lowers the sintering temperature to T≤900 °C, enabling co-firing of the ferrites with Ag metallization for multilayer technologies. However, low-temperature firing reduces the permeability to μ′=10 and the resonance frequency is shifted to 1 GHz. Thus substituted hexagonal Y-type ferrites can be used as soft magnetic materials for multilayer inductors for high frequency applications. © 2012 Elsevier B.V. All rights reserved.

The present invention relates to an improved process for producing highly ordered nanopillar or nanohole structures, in particular on large areas, which can be used as masters in NIL, hot embossing or injection molding processes. The process involves decorating a surface with an ordered array of metal nanoparticles produced by means of a micellar block- copolymer nano-lithography process; etching the primary substrate to a depth of 50 to 500 nm, where the nanoparticles act as a mask and an ordered array of nanopillars or nanocones corresponding to the positions of the nanoparticles is thus produced; using the nanostructured master or stamp in a structuring processes. Also the finished nanostructured substrate surface can be used as a sacrificial master which is coated with a continuous metal layer and the master is then etched away to leave a metal stamp having an ordered array of nanoholes which is a negative of the original array of nanopillars or nanocones.
