Boosting Electrochemical Performance via Extra-Role of La-Doped CeO Interlayer for "Oxygen Provider" at High-Current SOFC Operation.

Utilizing rare earth doped ceria in solid oxide cells (SOCs) engineering is indeed a strategy aimed at enhancing the electrochemical devices' durability and activity. Particularly, Gd-doped ceria (GDC) is actively used for barrier layer and catalytic additives in solid oxide fuel cells (SOFCs). In this study, experiments are conducted with La-doped CeO (LDC), in which the Ce sites are predominantly occupied by La, to prevent the formation of the Ce-Zr solid solution.

Plasmonic Conducting Metal Oxide-Based Optical Fiber Sensors for Chemical and Intermediate Temperature-Sensing Applications.

The demand for real-time sensors in harsh environments at elevated temperature is significant and increasing. In this manuscript, the chemical and temperature sensing using the optical response through the practical fiber platform is demonstrated, and principle component analysis is coupled with targeted experimental film characterization to understand the fundamental sensing layer properties, which dominate measured gas sensing responses in complex gas mixtures. More specifically, tin-doped indium oxide-decorated sensors fabricated with the sol-gel method show stable and stepwise transmission responses varying over a wide range of H concentration (5-100%) at 250-350 °C as well as responses to CH and CO to a lesser extent.

Distributed Optical Fiber Sensors with Ultrafast Laser Enhanced Rayleigh Backscattering Profiles for Real-Time Monitoring of Solid Oxide Fuel Cell Operations.

This paper reports a technique to enhance the magnitude and high-temperature stability of Rayleigh back-scattering signals in silica fibers for distributed sensing applications. With femtosecond laser radiation, more than 40-dB enhancement of Rayleigh backscattering signal was generated in silica fibers using 300-nJ laser pulses at 250 kHz repetition rate. The laser-induced Rayleigh scattering defects were found to be stable from the room temperature to 800 °C in hydrogen gas.

A hyaluronate-atelocollagen/beta-tricalcium phosphate-hydroxyapatite biphasic scaffold for the repair of osteochondral defects: a porcine study.

The authors had devised a novel biphasic scaffold combining hyaluronic acid and atelocallagen for the chondral phase and combining hydroxyapatite and beta-tricalcium phosphate for the osseous phase. Sixty-four osteochondral defects were created in the knee joints of 16 minipigs to evaluate the effectiveness of this scaffold for repairing cartilage in a large animal model. The defects were divided into five groups according to their treatment: filling with a cell/biphasic scaffold composite (Group I, 16 defects); implanting only the biphasic scaffold (Group II, 16 defects); placing the removed osteochondral fragments back into the defect (Group IIIa, 8 defects); autologous chondrocyte implantation (Group IIIb, 8 defects); leaving the defects empty (Group IV, the negative control).

Development of a molecular marker specific to a novel CMS line in radish (Raphanus sativus L.).

In this study, we have investigated the cytoplasmic male sterility (CMS) of a novel male sterile radish line, designated NWB CMS. The NWB CMS was crossed with 16 fertile breeding lines, and all the progenies were completely male sterile. The degree of male sterility exhibited by NWB CMS is more than Ogura CMS from the Cruciferae family.
