    ABSTRACT:
    The future of the international accord on mitigating the impact of climate change is linked to the successful implementation of nano-technology. The latter is strongly dependent on finding commercially viable methods for nano-functionalization of the energy related materials. Drop-on-demand inkjet printing methods combining scalability and low equipment cost with high-resolution ink delivery have been proven a feasible solution in various areas: 2D functionalization — (i) fabrication of multifilamentary superconducting YBCO structures by inkjet printing of a low-fluorine YBCO precursor solution on SS/ABAD-YSZ/CZO substrates creating a multifilamentary structure by an inverse technique (Jc of up to 3 MA cm-2 at 77 K) [1]; (ii) in situ fabrication of conductive silver coatings without additional heat treatment from micron-sized elongated silver flakes [2].<br />3D functionalization — Composite solid oxide fuel cells LSCF/CGO cathodes were nano-engineered via "dual" inkjet printing infiltration. The structure was found to extend the active three-phase boundary and to promote adsorption/dissociation/surface exchange reactions. Electrochemical impedance tests showed a reduction in the polarisation resistance of between 1.5 and 7.0 times.
