Researchers at Beijing Institute of Technology have experimentally demonstrated anomalous topological pumping in hyperbolic lattices - a phenomenon impossible in conventional materials and Euclidean structures. Published in Science Bulletin, this work reveals how these curved-space structures can simulate high-dimensional quantum physics while exhibiting unique boundary-dependent transport.

A research team from the University of Basel, Switzerland, has developed a new molecule modeled on plant photosynthesis: under the influence of light, it stores two positive and two negative charges at the same time. The aim is to convert sunlight into carbon-neutral fuels.

A study led by Jun Cheng from Xiamen University and collaborators introduces a new workflow for recommending relay catalysis pathways. The workflow uses large language models (LLMs) to extract and organize catalytic reaction data, and combines this with a self-built catalysis knowledge graph (Cat-KG). The system automatically filters and recommends high-quality, traceable multi-step pathways, helping researchers design catalytic reactions more efficiently.

POSTECH and SNU Discover Breakthrough Material for Carbon-Free Hydrogen Production.

All-inorganic CsPbI₃ quantum dots (QDs) are regarded as promising candidates for advanced display materials due to their outstanding optoelectronic properties. However, conventional high-temperature thermal injection methods struggle with precise bandgap tuning, making it challenging to achieve pure red emission from CsPbI₃QDs. Now, in a study published in Science Bulletin, researchers from Zhejiang University of Technology have developed a thermally stable ethylammonium (EA⁺) doping strategy for CsPbI₃ QDs, achieving Rec.2020-standard pure-red perovskite light-emitting diodes (PeLEDs) with a high external quantum efficiency exceed 26%. The key innovation lies in an in situ acid–base equilibrium reaction that generates thermally stable ethylammonium oleate. This allows for the successful synthesis of EA⁺-doped CsPbI₃ QDs via high-temperature thermal injection, enabling precise emission tuning (630-650 nm) and exceptional spectral stability. The breakthrough opens new avenues for high-performance display technologies.
