The microstructure and connectivity of the ionic and electronic conductive phases in composite ceramic membranes are directly related to device performance. Transmission electron microscopy (TEM) including chemical mapping combined with X-ray nanotomography (XNT) have been used to characterize the composition and 3-D microstructure of a MIEC composite model system consisting of a Ce0.8Gd0.2O2 (...

A lithium–bismuth–copper co-doped GDC composite (Ce 0.712 Gd 0.178 Li 0.05 Bi Cu 0.01 O 1.801 ) capable of sintering at ∼750 °C with an electrical conductivity 29.6 mS cm −1 was developed for the first time metal-supported solid oxide electrolysers.

BACKGROUND AND PURPOSE The purpose of this study was to retrospectively compare the packing performance of helical Guglielmi detachable coil (GDC) 18 (thickness, 0.0135-0.015 inch) with the packing performance of both helical GDC 10 (thickness, 0.010 inch) and complex Trufill/Orbit coils (thickness, 0.012 inch). MATERIALS AND METHODS From our data base, we selected aneurysms that were exclusi...

A novel dimming control scheme, termed as generalized (GDC), is proposed for visible light communication (VLC) systems. The basic idea of GDC to exploit adaptively time, spatial and signal domain resources enhancing performance under practical illumination constraints. In particular, satisfy the constraints, an incremental algorithm index mapping first achieve target optical power uniform illum...

The effects of the electrochemical oxygen reduction reaction (ORR) on surface single-phase perovskite cathodes are well understood, but its potential for use in a complex system consisting different material types is unexplored. Herein, we report how BaCO3 nanoparticles-modified La0.6Sr0.4Co0.2Fe0.8O3-δ-Gd0.2Ce0.8O2-δ (LSCF–GDC)-composite improved kinetics high-performing ceramic fuel cells. Bo...

The green electrochemical synthesis of ammonia (NH3) through solid electrolysis has been intensively investigated. This research reported an improvement NH3 production rate using in situ exsolution ruthenium (Ru) atoms into lanthanum strontium chromium ferrite perovskite (LaxSr1−xCryFe1−yO3−δ) catalyst. Ru was achieved by reducing the optimized stoichiometric La0.33Sr0.67Cr0.33Fe0.52Ru0.15O3−δ ...

BACKGROUND AND PURPOSE Ion implantation is a surface-modification technology that creates a borderless surface on protein-coated platinum; this change in physical and chemical properties on the surface of Guglielmi detachable coils (GDCs) appears to enhance cell proliferation and adhesion. Our purpose was to evaluate the effect of ion implantation on GDCs in an experimental aneurysm model. ME...
