Advances in the technology of micro-structured catalytic reactors depend crucially on the catalyst layer development. A detailed investigation on the influence of the different variables on the coating quality has lead to a procedure to coat commercial catalysts inside stainless steel microchannels with good adhesion and no loss of catalytic activity. A commercially available catalyst sample is directly slurry-coated inside the microchannels. These -structured catalysts are tested for the water-gas shift reaction and compared to powder samples that underwent the same procedure. Adhesion of an alumina coating depends on both the initial particle size and the degree of macro-porosity. The latter is influenced by the nature of the binder. In the case of the commercial catalyst the particle size was difficult to control as milling was found to deteriorate its activity. Binders that can form metal complexes should be avoided in order to prevent redispersion of the active phase.

In this paper we present the results obtained from the study of Ni-Ti alloy obtained by arc melting method. To define the alloy's shape, this is constrained under deformation and then heat treated. The heat treatment is performed at temperatures ranging between 325 -525°C. Shape memory bands were obtained from these ingots, with a band -thickness of 1mm and a band-width of 3mm, exhibiting shape memory properties. Ni-Ti bands were analyzed by Scanning Electron Microscopy (SEM) and X-ray fluorescence at room temperature. The results showed that the Ni-Ti bands possess super-elastic properties, and the transformation temperature is -10°C; also, it has been noticed that the alloy has a higher content of titanium and exhibit shape memory effect. Based on the results obtained within this project, an actuator with improved properties for industrial applications will be realized.
