  摘要：Solution-processed light-emitting diodes based on non-toxic copper-iodide hybrids1 are a compelling solution for efficient and stable deep-blue lighting, owing to their tunability, high photoluminescence efficiency and environmental sustainability2. Here we present a hybrid copper-iodide that shows near-unity photoluminescence quantum yield (99.6%) with an emission wavelength of 449 nm and colour coordinates (0.147, 0.087), alongside its emission mechanism and charge transport characteristics....

  摘要：Achieving long-term underwater adhesion to dynamic, regenerating soft substrates that undergo extreme fluctuations in pH and moisture remains a major unresolved challenge, with far-reaching implications for healthcare, manufacturing, robotics and marine applications1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15-16. Here, inspired by remoras-fish equipped with specialized adhesive discs-we developed the Mechanical Underwater Soft Adhesion System (MUSAS). Through detailed anatomical, behaviou...

  摘要：Studies of ancient DNA from cemeteries provide valuable insights into early human societies, and have strongly indicated patrilocality1, 2, 3, 4, 5, 6, 7, 8, 9-10. Here, we analysed ancient DNA alongside archaeological contexts and multiple stable isotopic data from 60 individuals in 2 separate cemeteries at the Fujia archaeological site in eastern China, dating between 2750 and 2500 bce. Our findings suggest the existence of an early-described matrilineal community in the Neolithic period, ch...

  摘要：Climate change may amplify the frequency and severity of supply-demand mismatches in future power systems with high shares of wind and solar energy1,2. Here we use a dispatch optimization model to assess potential increases in hourly costs associated with the climate-intensified gaps under fixed, high penetrations of wind and solar energy generation. We further explore various strategies to enhance system resilience in the face of future climate change. We find that extreme periods-defined as ...
