Solid Oxide Fuel cells operating at temperatures below 800 C (also known as intermediate temperature solid oxide fuel cell, IT-SOFC) are currently the topic of much research and development owing to the high degradation rates and materials costs incurred for SOFC operating at temperatures above 900 C. Thin films of electrode and electrolyte layers is one of the ways to achieve high performances in IT-SOFC. Yttrium oxide sputtering target can be used for physical vapor deposition of thin films of yttria stabilized zirconia layers for IT-SOFC. Yttrium containing films are used as thermal barrier and protective coatings in thermoelectric devices, rare earth doped yttrium oxide films are studied for phosphor applications.

Chipping failures observed clinically in bilayer systems of porcelain and zirconia restorations should be coupled with a monoclinic to tetragonal phase transformation in the zirconia layer due to the high compressive stress. Phase transformations were mapped using 2D micro X-ray

An extremely thin bilayer electrolyte consisting of yttria-stabilized zirconia (YSZ) and gadolinia-doped ceria (GDC) is successfully fabricated on a sintered NiO-YSZ substrate. Major processing flaws are effectively eliminated by applying local constraints to YSZ nanoparticles, and excellent open circuit voltage

Highly luminescent-paramagnetic nanophosphors have a seminal role in biotechnology and biomedical research due to their potential applications in biolabeling, bioimaging, and drug delivery. Herein, the synthesis of high-quality, ultrafine, europium-doped yttrium oxide nanophosphors (Y(1.9)O(3):Eu(0.1)(3+)) using a modified sol-gel technique is

The interest in electrophoretic deposition (EPD) for nanomaterials and ceramics production has widely increased due to the versatility of this technique to effectively combine different materials in unique shapes and structures. We successfully established an EPD layering process with submicrometer
Y(2)O(3):Er(3+) nanorods are synthesized by means of a hydrothermal method and then introduced into a TiO(2) electrode in a dye-sensitized solar cell (DSSC). Y(2)O(3):Er(3+) improves infrared light harvest via up-conversion luminescence and increases the photocurrent of the DSSC. The rare
