Constraining Annual Coal Mine Methane Emissions with Multitemporal Hyperspectral Satellite Observations

Abstract Methane emissions from coal mining are difficult to constrain because of temporal variability and sparse observations. We used multitemporal hyperspectral observations from GF5A, GF5B, ZY1E, and ZY1F to quantify facility-scale emissions and evaluate sampling requirements...

Robust Quasi-Continuous-Wave Exciton–Polariton Lasing in Tin Halide Perovskite Nanowires under Ambient Conditions

Abstract Tin halide perovskites are promising lead-free optical gain media, yet stable quasi-continuous-wave/continuous-wave (quasi-CW/CW) lasing remains challenging under practical operating conditions. Here, we demonstrate robust quasi-CW lasing from single-crystalline CsSnBr3...
