Corrosion and contact ohmic resistance of the stainless steel current collectors in molten carbonates is one of the greatest obstacles to widespread application of molten carbonate fuel cells (MCFC). We simulate the variation of material parameters values, accounting for the impact of corrosion of the metallic current collectors on the performance of the porous cathode. Furthermore, we couple a ...

Magnetic Ratchet

Department of Physics, University of Bielefeld, Germany

Transport phenomena in spatially periodic magnetic systems, in particular the directed transport of magnetic beads in a so called magnetic ratchet (Brownian motor) are considered. Simulations are carried out to test and optimize this system, where the Smoluchowski equation with flux terms for the magnetic and gravitational force is used. Furthermore, experiments are carried out to verify the ...

The objective of this work has been to realize a feasibility study of a cooling device for a SQUID sensor using liquid nitrogen flowing through micro channels. The design consists of an epoxy cylindrical vacuum vessel skewed by a silicon microchannel heat sink. The SQUID sensor is situated directly on top of the microchannel heat sink. The device is used at room temperature and should be able to ...

Numerical Modelling of Electrophoresis Applied to Restoration of Archaeological Organic Materials

Restoration of archaeological materials from oceans is a major activity of Arc’ Antique. Organic materials such as wood, tissues, leathers, papers and ceramics found in sea water are always impregnated with salts. Rinsing such archaeological objects with pure water to extract the salts takes too long, so electrophoresis was used to improve the salt extraction. The objective of this ...
