“…In broad terms these and their related cubic crystal structures describe materials of the types: Brownmillerite, A 2 Detailed explanations of the crystallography and microstructures of these materials are outside the scope of the present text and can be found in the literature, see e.g. (1,2). It suffices here to say that these structures are enough similar that gradual changes from one to another can take place when concentrations of cations are changed over big ranges.…”

This paper gives a brief description of the important role that the ionic and mixed conducting ceramics (IMCC) type of materials will play in the R&D of energy and environment technologies of the -presumably -near future. IMCC materials based technologies for energy harvesting, conversion and storage as well as for monitoring and protection of our environment are exemplified. The strong impact of the international IMCC research on development of devices based on such materials is illustrated, and some recent trends in the scientific exploration of IMCC are highlighted. Important groups of genuine IMCC are the fluorite and perovskite structured metal oxides that have proven practically applicable, but also fine structured composite materials consisting of separate, but well mixed, electronic and ionic conducting phases may do the job of a mixed ionic and electronic conductor (MIEC). Recent years' research has pointed to ever more complicated multiphase structures that have superior performance.

“…Pt-paste (Metalor) electrodes were applied as current collectors on each side of the 3D sample and then fired at 900 ºC for 30 min. The geometrical area was 0.196 cm 2 . Impedance Regarding SOFC technology, the development of alternative approaches to simultaneously control both the macrostructure (flat/tubular configurations) and the microstructure (distribution/patterning of porosity, Triple Phase Boundary (TPB) optimization, thickness of layers, etc.)…”

“…The design of these microstructures may be a key issue, having an impact in parameters such as performance, mechanical stability, optimisation of gas flow-paths to/from the reaction sites, thermal instability and depending on the materials, redox cycling. Furthermore, in most of the cases, the engineered microstructures must be stable at high temperatures, as is the case of the thermal cycles in Concentrating Solar Power when the temperatures may reach values close to 1500 ºC, or in YSZ-based components in SOFC technology, which are typically sintered at 1400 ºC to produce gas-tight materials (2).…”

Artificial photosynthesis in nanobiocatalytic assemblies aims to reconstruct man-made photosensitizers, electron mediators, electron donors, and redox enzymes for solar synthesis of valuable chemicals through photochemical cofactor regeneration. Herein, we report, for the first time, on nanobiocatalytic artificial photosynthesis in near-infrared (NIR) light, which constitutes over 46% of the solar energy. For NIR-light-driven photoenzymatic synthesis, we synthesized silica-coated upconversion nanoparticles, Si-NaYF4:Yb,Er and Si-NaYF4:Yb,Tm, for efficient photon-conversion through Förster resonance energy transfer (FRET) with rose bengal (RB), a photosensitizer. We observed NIR-induced electron transfer by using linear sweep voltammetric analysis; this indicates that photoexcited electrons of RB/Si-NaYF4:Yb,Er are transferred to NAD+ through a Rh-based electron mediator. RB/Si-NaYF4:Yb,Er nanoparticles, which exhibit higher FRET efficiency due to more spectral overlap than RB/Si-NaYF4:Yb,Tm, perform much better in the photoenzymatic conversion.
