We present an experimental, theoretical, and computational study of the spreading of a millimetric silicon oil drop under the excitation of a surface acoustic wave (SAW), traveling in the underlying solid substrate. Our theoretical model, formulated

Bi2Ca2Co1.7Ox bulk polycrystalline ceramics were prepared by the solid state method and by directional growth. Moreover, the effect of annealing on the textured materials has been studied. Microstructure has shown randomly oriented grains in the clas

Bi1.6Pb0.4Sr2Co1.8Ox thermoelectric ceramics with small Ag additions (0, 1, and 3 wt.%) have been successfully produced by a sol-gel method via nitrates. Microstructure has shown a reduction on the amount of secondary phases and an increase on the bu

Several solution synthetic methods, sol-gel and a polymeric route, have been studied in order to obtain Bi2Sr2Co1.8Ox ceramics with improved thermoelectric properties, compared to the classical solid state reaction. The products obtained by these dif

Thermoelectrical properties of cobaltite ceramics can be tuned up by choosing the adequate synthetic method, cation substitution and subsequent grain orientation. This can be performed preparing the ceramics by a polymer solution method, using Pb par

Thermoelectric performance on cobaltite ceramics can be increased raising the electrical conductivity. This can be performed by increasing grain size and aligning them along a preferential direction by the Laser Floating Zone (LFZ) method. In this wo

Vitreous cylinders with compositions Bi2-xPbxSr2CaCu2Oy, (x = 0, 0.2, 0.4 and 0.6) were prepared and used as precursors to fabricate textured bars through a laser floating zone melting method (LFZ). The resulting textured cylindrical bars were anneal

The addition of Ag into Bi-2212 compounds has demonstrated to be a suitable method to improve both, the thermal and mechanical properties as well as the electrical ones. The final properties have been found to be in strong dependence of Ag content an
