The aim of SELFMEM is to develop innovation in the field of nanoporous membranes. This will be achieved by taking advantage of the self-assembly properties of block copolymers leading to highly porous membranes with adjustable, regular-sized pores of tailored functionalities. Both polymeric and inorganic (silicon) membranes will be developed. In the case of isoporous polymeric membranes focus will be laid on the formation of integral-asymmetric block copolymer membranes with an isoporous top layer as a function of the block copolymer structure and the preparation conditions. Isoporous inorganic membranes will be prepared by using a thin block copolymer film as a mask for selective etching. The possibilities to systematically vary the pore size and density by varying the block copolymer mask structure will be investigated. The block copolymers will be synthesized by controlled polymerisation techniques (anionic, group transfer, and different radical polymerisations), depending on the chosen monomers. The characterisation during and after formation of the membranes will be carried out by light and various x-ray scattering techniques, by scanning force microscopy, and by different electron microscopic techniques. Both types of membranes will be post-functionalized in order to tune their final properties. The membranes will be tested for their applicability in different areas. Separation of gases (like H2/CO2) and proteins as well as water purification will be addressed in this project. Modeling and theory will support the understanding of the structure formation of these membranes and help to optimise membrane design. The results of SELFMEM will increase European competitiveness in strategic markets such as gas purification, water treatment and molecular biology. The consortium consists of 12 partners from 10 countries, including 4 companies from 3 countries.

BIO-GO-For-Production is a Large Scale Collaborative Research Project that aims to achieve a step change in the application of nanocatalysis to sustainable energy production through an integrated, coherent and holistic approach utilizing novel heterogeneous nanoparticulate catalysts in fuel syntheses. BIO-GO researches and develops advanced nanocatalysts, which are allied with advanced reactor concepts to realise modular, highly efficient, integrated processes for the production of fuels from renewable bio-oils and biogas. Principal objectives are to develop new designs, preparation routes and methods of coating nanocatalysts on innovative micro-structured reactor designs, enabling compact, integrated catalytic reactor systems that exploit fully the special properties of nanocatalysts to improve process efficiency through intensification. An important aim is to reduce the dependence on precious metals and rare earths. Catalyst development is underpinned by modelling, kinetic and in-situ studies, and is validated by extended laboratory runs of biogas and bio-oil reforming, methanol synthesis and gasoline production to benchmark performance against current commercial catalysts. The 4-year project culminates in two verification steps: (a) a 6 month continuous pilot scale catalyst production run to demonstrate scaled up manufacturing potential for fast industrialisation (b) the integration at miniplant scale of the complete integrated process to gasoline production starting from bio-oil and bio-gas feedstocks. A cost evaluation will be carried out on the catalyst production while LCA will be undertaken to analyse environmental impacts across the whole chain. BIO-GO brings together a world class multi-disciplinary team from 15 organisations to carry out the ambitious project, the results of which will have substantial strategic, economic and environmental impacts on the EU petrochemicals industry and on the increasing use of renewable feedstock for energy.

The role of dendrimers as encapsulating, stabilizing, or directing agents for inorganic nanoparticles (NP) is presented. The construction of dendrimers can be carried out in two major ways that includes by a divergent approach, where the molecule grows from the center to the periphery, and a convergent approach, where the dendrimer molecule is built starting from the periphery fragments. NP synthesis in the presence of dendrimers is carried out using procedures similar to those developed for NP formation in the presence of surfactants or polymers. Metal oxide NP are formed by oxidation of metal compounds at high pH or/and using H 2O 2 or CO 2 as oxidants. Semiconductor metal halide NP can be obtained by numerous techniques including thermal decomposition of organometallic compounds, interaction of metal oxide with elemental S or Se or nteractions of metal cations with halide anions such as Cd 2-.

A method of reductive amination without an external hydrogen source is reported. Carbon monoxide is used as the reductant. The reaction proceeds efficiently for a variety of carbonyl compounds and amines at low catalyst loadings and is mechanistically interesting as it does not seem to involve molecular hydrogen. Look, no H2! Reductive amination without an external hydrogen source has been developed using carbon monoxide as the reductant and rhodium acetate (0.2-1mol %) as catalyst. The method tolerates a variety of functional groups and provides target amines in good to excellent yields. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Polymeric cryogels, the gels formed in moderately frozen gelling systems, have been empirically known for many decades, but systematic scientific research on various cryogels and the peculiarities of cryotropic gel formation only commenced at the beginning of the 1980s. This historical review briefly describes the principal stages of the studies on these very interesting gel materials. It also discusses some mechanisms of their formation, as well as summarizes published data on the main representatives of chemically crosslinked (covalent), ionically linked, and noncovalent (physical) cryogels. © Springer International Publishing Switzerland 2014.

POLYCAT provides an integrated, coherent and holistic approach utilizing novel polymer based nanoparticulate catalysts in pharmaceutical, crop protection and vitamin syntheses in conjunction with the enabling functions of micro process technology and green solvents such as water or ethyl lactate. This provides a discipline bridging approach between fine chemistry, catalysis and engineering. This will lead to the replacement of a number of chemical or microbiological reaction steps in fine chemical syntheses by catalytic ones using more active, selective and stable nanoparticulate catalysts. In addition, POLYCAT will lead to the development of novel chiral modifiers immobilized on the polymeric supports. Micro process technology provides testing under almost ideal processing conditions, with much improved heat management, with improved costing, at high data validity, at high process confidence, and with high certainty for scale-out. The industrial applicability is demonstrated by scale-out of the industrial demonstration reactions to the pilot scale. A multi-purpose, container-type plant infrastructure will integrate individual reaction and separation modules in block format, standardised basic logistics, process control, safety installations, and on-line analytics. As guidance before (ex-ante) and during the whole development, holistic life cycle (LCA) and cost analyses will pave directions towards competitiveness and sustainability. The POLYCAT technologies have potential to reduce the environmental impact by 20% up to orders of magnitude: e.g. reduction of green house gas emissions, acids (SO2-Eq.), nutrients (NOx-Eq.), toxic substances (1,4-DCB Eq.) and finite abiotic resources (antimony eq.). With (enantio)selectivity increases up to 25%, solvent reductions of 30-100%, and products cost decreases of about 10%, a midterm impact of 30-110 Mio Euro and longterm impact of 100-560 Mio Euro result.

There is a continuous interest to apply homogeneous catalysis to asymmetric synthesis, which is the elective method for drugs production in pharmaceutical industry. Asymmetric catalysis provides the cheapest synthetic route to optically active compounds with minimal number of steps and reduced use of expensive chiral substrates. Replacing conventional methods with those involving asymmetric catalysis is then mandatory to reduce considerably energy/materials costs and the environmental impact of chemical manufacturing. The improvement of either efficiency and selectivity of traditional molecular chiral catalysts is a time consuming and expensive procedure that may be bypassed by the development of the innovative "modular catalysis" on which the MODUCAT proposal is concerning. The accomplishment of MODUCAT milestones will boost the application of asymmetric catalysts to several industrial processes. The main objectives of the project are: (1) to develop the modular assemblage of a chiral catalyst consisting of two independent units, separately responsible for activity and enantioselectivity. Such units, assembled together by Coulombic and/or hydrophobic forces, should form an innovative catalyst conjugating activity with enantioselectivity; (2) to validate the MODUCAT ideas in model catalytic asymmetric processes carried out in aqueous media. While the few known examples of "modular catalysts" find application in non-polar media, we propose to use Ag/Au NPs functionalized with SAMs of optically active charged molecules to bring about the modular approach in polar solvents. While the Fellow's background in catalysis, organometallic/colloidal chemistry, particularly dealing with charged NPs, is a big asset that guarantees high chance to reach the goals of the project, his training in preparation of water soluble catalysts and their application to aqueous systems, where the Host has a recognized experience, is a fundamental prerequisite for the success of the project.
