Prof. Christoph Müller (ETH Zürich)19/09/2013, 09:30invited talkOwing to the increasing concentration of CO2 in the atmosphere and the climate change associated with it, there is increasing pressure to reduce the anthropogenic emissions of CO2. CO2 capture and storage (CCS) is a mid-term solution to mitigate climate change. However, the currently technologically available CO2 capture technique, i.e. amine scrubbing has very high, potentially prohibitively...Go to contribution page

Mr Georges Siddiqi (ETH Zurich)19/09/2013, 10:00invited talkTransition metal catalysts play a central role in the formation of polyethylene (PE), a bulk commodity material made on over 80 million metric tons per year. The Phillips catalyst, which contains chromium dispersed on silica, was the first commercialized material that could produce PE industrially and accounts for 40 – 50 % of global high density PE. Despite 60 years of intensive research the...Go to contribution page

Prof. Carlo Lamberti (Department of Chemistry, Turin University)19/09/2013, 10:30invited talkTwo classes of structurally complex materials will be discussed in this talk. The first concerns iso-structural UiO-66/67 [JACS, 2008, 130, 13850] metal-organic frameworks that showed some interest for H2 storage and some potentialities as porous scavengers for interim radioactive waste scavenger. UiO-66/67 exhibits a different degree of long- and short-range order that has been disclosed...Go to contribution page

Felix Buechi (Paul Scherrer Institut)19/09/2013, 11:20invited talkPolymer electrolyte fuel cells (PEFC) are electrochemical reactors, strongly governed by fluid mechanical processes. Heat, charge and multiphase mass transport on length scales from nanometers, up to meters are interlinked. Carbon fibre based gas diffusion layers (GDL) with a thickness in the order of 200 μm bridge the scale gap between the catalyst layer (sub-µm structures) and channel/rib...Go to contribution page

Vanessa Wood (ETH Zurich)19/09/2013, 11:50invited talkRealization of high performance lithium ion batteries requires the development of roadmaps for achieving favorable porous electrode microstructure through the selection of active materials, additives, and electrode processing conditions. To develop such roadmaps, a clear understanding of battery microstructure is needed. We report the use of synchrotron radiation x-ray tomographic microscopy...Go to contribution page

Dr Martin Mansson (Laboratory for Quantum Magnetism (LQM), EPF Lausanne)19/09/2013, 14:30invited talkOne of the most important scientific problems to solve for our modern society is how to convert and store clean energy. In order to accomplish a paradigm shift in this field we need to understand the fundamental dynamical processes that govern the transfer of energy on an atomic scale. For future energy devices like solid-state batteries (SSB) as well as solid-oxide fuel cells (SOFC) this...Go to contribution page

Peter Georgiev (University of Sofia)19/09/2013, 15:00invited talkThe substantial effort by many groups around the world to solve the problem of storing large amounts of hydrogen in the fuel tank of a car, along with facile release of and recharging with H2 at near-ambient conditions, has not yet resulted in a practical system. One common approach has been to utilize adsorption of H2 in porous materials, which have favourable adsorption/desorption...Go to contribution page

Dr Sandor Balog (Adolphe Merkle Institute, University of Fribourg)19/09/2013, 15:30invited talkThe fuel cell, using a polymer electrolyte, is a clean and efficient electrochemical energy conversion device and is attractive for portable electronics, distributed power source, and electric vehicle applications. The limited lifetime and the high cost of commercially available electrolytes, however, block the large-scale commercialization. Radiation-grafted copolymers have attracted...Go to contribution page

Dr Jens Wenzel Andreasen (Technical University of Denmark)19/09/2013, 16:20invited talkThe structure and architecture of polymer solar cells on scales from nm to mm have crucial impact for the device performance. With standard X-ray scattering techniques, we may determine donor and acceptor domain sizes in polymer solar cells, crystalline structure and characterize the dimensionality of the interface, but to quantify the capability of the nanostructure for separating...Go to contribution page

Dr Ingo Manke (HZB)19/09/2013, 16:50invited talkTomography and radiography are non-destructive investigation methods that are successfully applied in various fields in materials science and fundamental research. Neutron and x-ray imaging can be used for investigation of polymer electrolyte membrane fuel cells (PEMFC) and their components on different length scales. X-ray imaging resolves inner sample details with micrometric spatial...Go to contribution page
