Advanced Optical Materials, Volume 13, Issue 7, March 4, 2025.Visible‐frequency hyperbolic metasurfaces (HMSs) are explored for their super‐resolution capabilities. Near‐field measurements reveal anomalous focusing, sub‐wavelength imaging, and angle‐independent, reflectionless negative refraction across HMS interfaces. This study highlights HMSs as a powerful platform for on‐chip super‐resolution imaging and wave

Sea Ice Modulates Air–Sea Methane Flux in the Southern Ocean
Geophysical Research Letters, Volume 52, Issue 1, 16 January 2025.Abstract The Southern Ocean (SO) is predicted to be a weak sink for atmospheric CH4, although the magnitude is uncertain due to a lack of observations of the marginal ice zone (MIZ). Using both eddy covariance and bulk formula flux measurements from the icebreaker R/V Xuelong2, we found that the eastern SO during an austral summer was a sink for CH4 ...

Prediction of airport surface potential conflict based on GNN‐LSTM
IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.Identify potential conflict hot spots at Shenzhen Bao'an an International Airport based on taxi paths and model the taxiway structure. Use the GNN‐LSTM model to predict the number of potential departure conflicts. Finally, the effectiveness and superiority of the method are verified through comparative experiments. Abstract The development of the civil

Exergy analysis of isochoric and isobaric adiabatic compressed air energy storage
IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.This paper develops an exergy analysis comparing three adiabatic compressed air energy storage system layouts, operating under isochoric and isobaric modes. Abstract Adiabatic compressed air energy storage (ACAES) is an energy storage technology that has the potential to play an important role in the transition to a predominantly renewables‐driven net ...
