Around the poles, ice accumulated over millions of years can reach depths of several kilometers. The undisturbed deep ice preserves information about the past. The air bags and particles trapped in the ice tell scientists what the atmosphere used to be like. This has aroused great interest among paleoclimatologists in glacier ice cores.By regularly sampling the ice core at its depth, they can reco...
The widespread application in the fields of optical communication, computing, and sensing continues to drive the growing demand for high-performance integrated photonic components. Recently, Ali Najjar Amiri of Kochi University in Türkiye and other scholars proposed a highly scalable and highly flexible deep photonic network platform, which is used to realize optical systems on chip with arbi...
Organic polymer semiconductor materials, due to their unique molecular structure and weak van der Waals interactions, are endowed with the characteristics of soluble processing and easy flexibility, and have potential applications in portable and implantable medical monitoring devices. A highly flexible, skin conformal, and excellent spatial resolution X-ray detector is expected to be integrated w...
In the process of selecting electric vehicles, the effectiveness of the heating system is often overlooked. However, this system is crucial for providing a warm and comfortable driving environment and removing frost and fog from winter windows. More importantly, it can also improve battery efficiency, as the battery performs best within a specific temperature range.Unlike internal combustion engin...
