May 8th 2012

08:30 Registration & coffee
09:00 Li-ion batteries - synchrotron studies of materials in motion
 
  • Processes in a battery are complex
  • The knowledge about the lithium-ion mobility in the bulk electrode, the electrolyte materials and electrode/electrolyte interfaces is crucial for new or improved battery concepts
  • Characterization methods at different synchrotron radiation sources are improving the general understanding of the mechanisms occurring in a battery in operation

09:45 Clean water and hydrogen from sunlight
 
  • Providing safe clean drinking water and sustainable energy for all the World's population is of enormous importance
  • In principle, sunlight is all one needs to purify and disinfect water and to split water to make fuels such as hydrogen
  • But photocatalysts are poorly understood and not efficient enough.
  • Have we missed something essential?

10:10 Towards the Simulation of redox reactions
 
  • Fundamental aspects of non-equilibrium redox reactions
  • Examples: Charging of Galvanic cells, contact electrification
  • The challenge of modeling redox reactions with atomistic simulations
  • Solutions to the problem and first demonstrators

10:30 Refreshment break & networking
11:00 Biofilms as complex films
 
  • Biofilms are heterogeneous communities of bacteria
  • What is the key process that enables them to live even in the most extreme environments?
  • A common hallmark of all bacterial biofilms is the production of a polymeric matrix that holds the community together.
  • Can we understand and manipulate this process?
  • Biofilms colonize surfaces efficiently. How does that depend on their material properties?

14:30 Foaming of polypropylene nanocomposites.
 
  • Closed-cell PP nanocomposite foams are produced with cell sizes lower and cell concentration higher than for the neat polypropylene.
  • The effect of nanofibers and nanoplatelets both on the extensional viscosity of linear polypropylene and on the cell size, cell concentration and bulk density of PP-based foams will be discussed
  • The influence of die temperature and extrusion speed on the structure of PP nanocomposite foams is presented
  • Nanofibers or nanoplatelets are located in cell walls of growing bubbles and prevent their coalescence

14:50 Refreshment break & networking
15:20 Thickness reinforcement of composite materials with z-pins
 
  • Composite materials such as CFRP have excellent mechanical in-plane properties in relation to their density
  • Compared to in-plane properties, out-of-plane properties are very low due to the lack of fibers oriented in the through-thickness direction
  • state of the art and the influence of z-pins on the mechanical properties will be discussed
