Ceramic multi-layer systems are the key components of solid oxide cells (SOC) to be used either for power generation or energy storage. Over the last decades continuous improvement in materials, architecture and manufacturing processes have been achieved to improve performance, durability and lifetime. The advanced co…
MgAl2O4 coatings, used for electrical insulation along the metallic seals in high temperature fuel cell stacks, tend to fail prematurely due to generated stresses during on-off thermal cycles. To enhance stress bearing capability and the durability of these coatings, self-healing was investigated by introducing additi…
In this study, we prepared higher manganese silicides (HMS) containing small amount of MnSi or silicon nano-particles to study the energy dependent scattering effect, which had been reported to improve the power factor. The samples were prepared in induction furnace followed by liquid quenching technique, to obtain fi…

Among the many proposed hollandites compositions (Bax,Csy)(M,Ti)8O16, Ga substituted hollandite has been studied to a limited extent. By substituting Ti with Ga, hollandite can be synthesized with a standard sintering process producing dense ceramics at relatively low temperature of 1250°C. In the present work, Ga sub…

Ti3AlC2 is one of the many compounds which belong to the very interesting group of materials called MAX phases. The MAX phases are heterodesmic layered materials with different chemical bonds which strongly influence their properties locating them between metals and ceramics. They are characterised with high elastic m…
While Ceramic Matrix Composites are achieving significant interest and showing durability enhancements over metals in certain applications, there are still significant hurdles to overcome for widespread acceptance. Key material properties are sometimes still assumed and novel test approaches are needed. Non-destructiv…

Solid electrolyte dendrites of yttria stabilized zirconia with spatially ordered porous structures were successfully fabricated for fuel cell miniaturizations by stereolithography of additive manufacturing. Micrometer order ceramic lattices with the coordination numbers 4, 6, 8 and 12 were propagated spatially in comp…
This study has investigated on the photocatalytic behavior of the nanocrystalline TiO2 coupled with long lasting phosphorescent materials. Nanocrystalline titanium dioxide layers were directly deposited on the long lasting phosphor plates of strontium aluminates, Sr4Al14O25:Eu2+,Dy3+, by low-pressure chemical vapor de…
At Fraunhofer IKTS, appropriate processes and methods for the development of customized, application-specific SOFC concepts and prototype systems have been established during various projects in the past, funded by public bodies and industrial customers. As an outcome of the cell and stack developments during the past…

A research article published in this journal by Sotelo et al. (2016) reported on characterization of collagen from different discarded fish species obtained from the Iberian Peninsula located in the southwest corner of Europe. While the original research contributed new information to the literature, the authors did n…
Toward the application of SiC/SiC composite materials to gas turbine engines and rocket engines, R & D of SiC/SiC composite has been intensively continued, where original NITE process using aqua-slurry of nano-SiC powders has been improved to DEMO-NITE process using polymer based slurry of nano-SiC powders. Followed t…

Scientific Reports 6: Article number: 21484; published online: 19 February 2016; updated: 31 May 2016 In this Article, some instances of ‘(A = Sr and Ba)’ are incorrectly written as ‘(A = Sr and Bi)’.
In recent years composite materials based on natural fibers are more and more used for their new performances. Natural fibers propose attractive environmental, mechanical and thermal properties.In this work, we are firstly interested in hemp fibers. These fibers are already used in the automotive and construction indu…
