Origin of Ultraviolet‐Induced High‐Temperature Photovoltaic Response at Pt/Gd‐Doped CeO2 Interface

Advanced Optical Materials, EarlyView.
Oxygen uptake induced by UV irradiation generates an oxygen chemical potential gradient across acceptor‐doped ceria at high temperatures. Besides the photovoltage caused by band bending at the heterojunction interface, the observed voltage can also be attributed to the Nernst voltage arising from the oxygen potential gradient.

Damage tolerance of six dental zirconias with different translucencies

Biomaterial Investigations in Dentistry, 2020
Purpose High-translucent dental zirconia has been introduced as a suitable material for anterior monolithic restorations. The material composition differs from traditional 3Y-TZP both with regard to yttria content and grain size.

Directional Light Scattering In Mie‐Resonant Si Particles With Ultra‐Thin Au Shells

Advanced Optical Materials, EarlyView.
Si@Au core‐shell particles have been produced to study their ability to directionally scatter light. We found that the heavily reported particulate shells do not overlap the electric and magnetic dipoles well, where continuous shells have better overlap. Experimental analyses, including nanomaterial characterization, EELS and single‐particle dark‐field

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.

Making yttria-stabilized tetragonal zirconia translucent [PDF]

Dental Materials, 2014
The aim of this study was to provide a design guideline for developing tetragonal yttria-stabilized zirconia with improved translucency.The translucency, the in-line transmission in particular, of 3mol.% yttria-stabilized tetragonal zirconia (3Y-TZP) has been examined using the Rayleigh scattering model.
