X-ray photoemission spectroscopy determination of the InN/yttria stabilized cubic-zirconia valence band offset [PDF]

, 2007
The valence band offset of wurtzite InN(0001)/yttria stabilized cubic-zirconia (YSZ)(111) heterojunctions is determined by x-ray photoemission spectroscopy to be 1.19±0.17 eV giving a conduction band offset of 3.06±0.20 eV.

Catastrophic Degradation in Solid Oxide Fuel Cells Caused by Air Supply Interruption in Real‐World Operations: Fundamental Mechanisms and Mitigation Strategies

Advanced Science, EarlyView.
Interrupting the air supply during the operation of solid oxide fuel cells leads to irreversible chemical degradation of the cathode materials, primarily driven by strontium at the A‐site of perovskite structures. Alternative strontium‐free materials effectively address this issue, ensuring high performance and reliable operation during operational ...

Extreme Thermal Cycling of Anode‐Supported Microtubular Solid Oxide Fuel Cells Using a Novel Test Setup

Advanced Energy and Sustainability Research, EarlyView.
A novel test setup is developed to perform extreme thermal cycling on microtubular solid oxide fuel cells (SOFCs). The tested microtubular SOFC shows excellent tolerance to over 100 extreme thermal cycles at heating/cooling rates of ≈175/100 °C min−1.

Contact damage in an yttria stabilized zirconia: Implications

Journal of Materials Science: Materials in Medicine, 2007
This paper presents the results of a combined experimental and computational study of contact damage in a 3 mole% yttria partially stabilized zirconia (3-YSZ) that is relevant to hip implants and dental restorations. Contact-induced loading in real applications is idealized using Hertzian contact model to explain plasticity phenomena and failure ...

Cathode Processing Optimization Toward Solid‐State Batteries with Monolithic Oxysulfide Glassy Solid Electrolytes

Batteries &Supercaps, EarlyView.
Mixing order and mixing time affect the ionic and electronic transport properties through a composite cathode made from lithium iron pyrophosphate, an oxysulfide glassy solid electrolyte, and conductive carbon. It is proposed that optimized milling conditions help create robust conduction networks in the composite. Seeking to further the development of

Atomically ordered solute segregation behaviour in an oxide grain boundary

Nature Communications, 2016
Solute segregation is challenging to experimentally identify at the atomic scale. Here, the authors report the direct observation of atomic site-dependent solute segregation behaviour in an yttria-stabilized zirconia grain boundary by atomic-resolution ...

Role of promoters over yttria‐zirconia supported Ni catalyst for dry reforming of methane

Energy Science & Engineering, 2023
Dry reforming of methane (DRM) bears great hope for the catalytic community as well as environmentalists for its potential to convert two greenhouse gases, CH4 and CO2, together into synthetic feedstock “syngas”.
