Fe-substituted (La,Sr)TiO3 as potential electrodes for symmetrical fuel cells (SFCs)

Description: In the work presented herein, the potential use of La4Sr8Ti12−xFexO38−δ (LSTF) materials as electrodes for a new concept of solid oxide fuel cells, symmetrical fuel cells (SFCs), is considered. Such fuel cells use simultaneously the same material as anode and cathode, which notably simplifies the as...

Performance of cubic-(La,Sr)TiO3+δ as SOFC anodes (La,Sr)TiO3+δ en lugar de (La,Sr)TiO3+d

Description: [EN] The performance and potential application of the cubic members of the La4Srn-4TinO3n+2 series of compounds, i.e. n≥12, prepared by solid state reaction are discussed. Although these phases can be indexed as cubic perovskites by X-ray diffraction (XRD), there exists some oxygen beyond the ABO3 s...

Mechanical characterization at nanometric scale of a new design of SOFC

Description: The mechanical stability is an important parameter to gain knowledge in the potential applications of a novel design of electrolyte-supported SOFC, based on yttria-stabilised zirconia (YSZ) and NiO-YSZ composites, with cross-linked channels (∼90 μm of diameter). In this experimental work, the mechan...

The effect of l-thymidine, acyclic thymine and 8-bromoguanine on the stability of model G-quadruplex structures

Description: Background Guanine-rich oligonucleotides are capable of forming tetrahelical structures known as G-quadruplexes with interesting biological properties. We have investigated the effects of site-specific substitution in the loops and in the tetrads model G-quadruplexes using thymine glycol nucleic aci...

Performance of a novel type of electrolyte-supported solid oxide fuel cell with honeycomb structure

Description: A novel design, alternative to the conventional electrolyte-supported solid oxide fuel cell (SOFC) is presented. In this new design, a honeycomb-electrolyte is fabricated from hexagonal cells, providing high mechanical strength to the whole structure and supporting the thin layer used as electrolyte...

CARMENES input catalogue of M dwarfs I. Low-resolution spectroscopy with CAFOS

Description: Context. CARMENES is a stabilised, high-resolution, double-channel spectrograph at the 3.5m Calar Alto telescope. It is optimally designed for radial-velocity surveys of M dwarfs with potentially habitable Earth-mass planets. Aims. We prepare a list of the brightest, single M dwarfs in each spectral...

Efficient scheduling of astronomical observations: Application to the CARMENES radial-velocity survey

Description: Context. Targeted spectroscopic exoplanet surveys face the challenge of maximizing their planet detection rates by means of careful planning. For a large planet survey, the number of possible observation combinations, i.e., the sequence of observations night after night, both in total time and amoun...
