In this paper, a novel method of Cu-Cu bonding by using the Cu nanosolder paste was proposed. The pure Cu nanoparticles used for preparing the Cu nanosolder paste were synthesized with simple routes and relatively high yields. The Cu nanoparticles were homogeneously dispersed with an average size around 60 nm. The sintering and bonding performance of Cu nanosolder paste were investigated, while an...
The properties of the structures made by ink-jet printing with the use of the ink containing nano silver sized particles are presented. After structures printing on substrate, to obtain good electrical conductivity, sintering process is necessary. It is shown, that thermal process influences strongly the resistance, and after the process the resistivity of printed structures can be only a little bit...
Yttria-stabilized zirconia has practical applications as an oxide ion conductor in several electrochemical devices (e.g. SOFC). It's expected that a formation of zirconia nanomaterial allows to improve its electrical properties. The investigated nanomaterials were prepared by sintering of the filter-pressed zirconia nanopowders. SEM observations reveal uniform microstructure with isometric grains...
Nanostructuring is one of the effective approaches to lower the thermal conductivity of materials. Nanostructured skutterudite-related compounds CoSb3, Fe0.5Ni0.5Sb3, Fe0.25Ni0.25Co0.5Sb3 and Te-doped CoSb3 were synthesized by a solvothermal route. The bulk materials were prepared by hot pressing or spark plasma sintering from the solvothermally synthesized nanopowders. The thermal conductivity values...
