Moiré Polariton Provides a New Path to Quantum Nonlinearity
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.
Ultra-high-energy gamma rays in the Cygnus Cocoon
What is the source of the highest-energy cosmic rays in our Galaxy? We report here the observation of the ultra-high-energy gamma-ray emission from a stellar superbubble in the Cygnus region, powered by the massive stellar complex called Cygnus OB2 in an attempt to answer this question.
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.
