In this work, porous catalytic membrane with tailored microstructure has been developed for the production of hydrogen from oxy-reforming process. Porous membranes have produced by freeze-casting ceria-based powders using camphene as solvent. The process parameters optimized in terms type and amount dispersant to obtain homogeneous stable ceramic suspension suitable process, while freezing temp...

Despite the high potential of freeze-casting technique for production porous inorganic substrates, there is a lack studies on tubular geometries and their mechanical behavior under different pressure scenarios. In this work, freeze-cast alumina substrates was assessed by mathematical models from experimental O-ring tests. The stress distributions revealed concentration tensile stresses (within ...

3D mili-scale channel representing simplified anatomical models of blood vessels were constructed in polidimethylsiloxane (PDMS). The objective was to obtain a sequential method to fabricate transparent PDMS models from a mold produced by rapid prototyping. For this purpose, two types of casting methods were compared, a known lost-wax casting method and a casting method using sucrose. The chann...
