The research team of Wang Jianli of the Chun Institute of Optics, President of the Chinese Academy of Sciences, has made progress in the observation of space objects based on metalens. In this study, the 2D concentric-ring structure, which is easier to process, is used as the basic configuration of the metalens, and the 2D meta-atoms are designed to be compatible with transverse electromagnetic wave and Transverse magnetic wave modes .Therefore, a portable telescopic system with a concentric-ring metalens with a diameter of 5cm as the main lens was developed, which achieve high-resolution detection within a 20° field of view, and further advances the deep application of metalens in the field of astronomical observation.

The continued intensification of global warming has made extreme heat events an increasingly severe threat to crop production. Cotton, as a globally important economic crop and a strategic pillar of China’s textile industry, faces significant challenges from frequent extreme high-temperature events during the summer. The high overlap between extreme heat and the blooming and boll-setting stages of cotton leads to issues such as pollen inactivation, anther non-dehiscence, and bud and boll shedding, severely affecting cotton yield and quality. This has become a critical bottleneck restricting the high-quality development of the cotton industry. Therefore, breeding heat-tolerant cotton capable of withstanding high-temperature stress has become an urgent need in the field of crop breeding.

Incorporating trace amounts of Cu atoms into n-type Bi₂(Te, Se)₃ simultaneously realizes lattice plainification and band structure engineering, thus substantially facilitating thermoelectric transport and leading to excellent device efficiencies.

Researchers have experimentally demonstrated a groundbreaking quantum imaging method using ultra-thin nonlinear metasurfaces. The study predicts unprecedented resolution and field of view by combining ghost imaging and all-optical scanning techniques, outperforming conventional bulky systems. This innovation has transformative potential for quantum sensing, imaging, and communications technologies.

In a landmark discovery, researchers applied a novel AI model called the max-logistic intelligence classifier to analyze 865,859 CpG methylation sites in early COVID-19 patients' blood samples. They uncovered compelling evidence that COVID-19 most likely originated from the natural synthesis of two rare but serious infectious diseases, glanders and Sennetsu fever, with some common human diseases.

A new study has unveiled a new strategy to enhance lithium-organic batteries by optimizing the active-site density, accessibility, and reactivity in polyimide cathode materials. This innovative approach offers the potential for batteries with higher capacity, faster charge rates, and improved cycling stability—pushing the boundaries of sustainable energy storage technology.

Researchers have achieved a monumental leap in the efficiency and stability of inkjet-printed quantum-dot light-emitting diodes (QLEDs) by employing a pressure-assisted thermal annealing (PTA) technique, which enables the acquisition of highly ordered quantum-dot (QD) thin films via inkjet printing. This innovative approach has propelled QLEDs to unprecedented external quantum efficiency (EQE) over 23%, signaling a significant step toward the mainstream adoption of this display technology.
