The microstructure of fine coal filter cakes governs their formation rate and dewaterability, which are both critical to the efficient benefication of fine coal. However, the principles by which the microstructure influences the transport properties of filter cakes are not well understood, partly due to the difficulty in obtaining information about the three-dimensional morphology of their pore structure...
X-ray photoemission spectroscopy was used to study thin nickel deposits on monocrystalline titanium dioxide surfaces. These surfaces were submitted before deposition to different kinds of treatment in order to obtain samples with various fixed bulk as well as surface stoichiometries. The influence of these stoichiometries on the electronic structure of deposited nickel was studied. Reducing thermal...
