The scientific objective of this proposal is to incorporate luminescent organoboron functionality into PFS-based block copolymers. In doing so, functional nanostructures will be created by crystallization-driven self-assembly, and their potential applications in nanoscale display technology, bioimaging, and biodiagnostics will be investigated. The exceptionally talented applicant, Dr. Hudson, has extensive experience in organoboron chemistry, luminescent materials chemistry and displays from his Ph.D. in Canada. The Manners group in the UK has well-known internationally-leading expertise in polymer and materials science, block copolymers, and crystallization-driven self-assembly. Thus, the experiences of Dr. Hudson and the Manners group are fully complementary and both are essential for the proposed research to succeed. At the end of the proposed 2 year fellowship period Dr. Hudson aims to return to Canada to a faculty position at a top research-intensive University.

A method for fabricating three-dimensional photonic crystal structures includes providing a layer of photosensitive material; introducing a laser beams into the material; reintroducing the laser beams into the photosensitive material during a second exposure; combining results from at least the first and second exposures to produce a three-dimensionally periodic pattern in the photosensitive material. A related system includes a laser source; a grating array having a plurality of diffraction gratings located thereon; a mask plate located on a photoresist layer and arranged in registration with the grating array; a rotating shutter arranged between the grating array and the laser source, said rotating shutter being suitable for periodically blocking light from the laser source; wherein each of the diffraction gratings is positioned and oriented so as to converge all first-order diffracted spots to a common point lying in a plane of a back side of the mask plate.

A zeolite which has a framework density of 10 to 16 T/nm<3> and a carbon content of 1 to 6 wt %, and satisfies the following (1) and (2): (1) it is an aluminophosphate wherein it has a nitrogen content of 0.5 to 12 wt % and wherein a part of aluminum is optionally substituted with Me, and (2) it is an silicoaluminophosphate wherein a part of aluminum is optionally substituted with Me and wherein when said silicoaluminophosphate is fired into a product having a carbon content of less than 0.3 wt %, the skeleton structure before the firing is retained, where in the above (1) and (2) the Me is at least one element selected from the elements belonging to 2A, 7A, 8, 1B and 2B Groups of the Periodic Table; a method for producing the zeolite; an adsorbent comprising the zeolite; and a heat utilization system or the like using the adsorbent.

The PEMFC represents one of the most promising technologies in the field of fuel cells. One of the keys to the success of the PEMFC technology is the development of improved electrolyte membrane materials which can be produced in mass and can operate within a temperature range of 130-200ºC. The ZEOCELL project will develop a nanostructured electrolyte membrane based on a new composite multifunctional material consisting of the combination of 3 materials: zeolites, ionic liquids and polymers -integrating their beneficial characteristics. The membrane will have an innovative structure comprising a 2D polymer matrix and two zeolite layers, with the following properties: - High ionic conductivity: ≥100 mS/cm at 150ºC.; - Suitability for operating at temperatures between 130-200ºC; - Good chemical, mechanical and thermal stability up to 200ºC; - Durability (<1% performance degradation during the first 1000 hours working); - Low fuel cross-over (

The urgency to identify and develop sustainable and timely solutions for our future society has become clearly demonstrated due to the alarming trends in global energy demand, the finite nature of fossil fuel reserves, the need to dramatically curb emissions of greenhouse gases to mitigate the devastating consequences of climate change, the damaging volatility of oil prices (in particular for the transport sector) and the geopolitical instability in supplier regions. In this regard, I started to work since my postgraduated studies in to find alternative and greener methodologies in terms of materials preparation, production of biofuels (which can partially meet the future expected needs of our society in terms of energy for transport), (photo)catalysis as a greener alternative for the production of chemicals and energy as well as biomass and waste valorisation. Biomass from plant is the most important feedstock for food, feed and non-food applications. In the processing of plant materials e.g. wood for paper, substantial amounts of potentially valuable by-products are produced. In this regard, the host organisation, Avantium Chemicals BV, explores unique bio-refinery concepts on novel routes for C6 carbohydrates conversion using nanomaterials. The main objectives are: 1)To develop a range of new multifunctional catalysts (e.g. based on mesoporous silica materials with controlled acidity and metal nanoparticles loading), through synthesis, using a combination of novel techniques 2)To screen their reactivity using model reactions 3)To develop an approach for testing selected catalysts using real feeds from e. g. the pilot plant 4)To optimise the reaction conditions (with emphasis on the reduction of energy consumption aand waste production), evaluation of the catalyst stability. 5)To integrate my knowledge and experience in heterogeneous catalysis into the Avantium R&D environment. In order to achieve these ambitious goals, I will use an interdisciplinary approach.
