By integrating an atomically-thin superlattice with a microcavity, we prepare a system to manipulate the quantum state with versatile flexibility, suggesting a new path to ultralow energy nonlinear photonic devices.
Achieving High Thermo-Mechanical Compatibility between Cathode and Electrolyte in Solid Oxide Fuel Cells
The delamination between cathode and electrolyte during cell fabrication or thermal cycling is one of the most typical failures due to their thermo-mechanical incompatibility. We achieved thermo-mechanical compatibility and high activity in an SOFC cathode by a thermal-expansion offset approach.
Flexible perovskites single-crystal devices can be realized with designed crystal morphology, orientation, thickness, size, and graded band structure.
Through topological conversion of non-van der Waals solids in chalcogen vapours and other vapors, ultrastable transition-metal chalcogenide monolayers with specific 2H/1T phases and high throughput production are achieved.
