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.

This paper presents the first demonstration of introducing 1,3-dithiane as a multifunctional additive into carbonate-based electrolytes. Through a unique "polarity reversal" mechanism and anion regulation effect, it simultaneously constructs inorganic-rich, high-ionic-conductivity interfaces on both cathode and anode. The Li||LiFePO₄ cells assembled with this strategy achieved a remarkable 83.6% capacity retention after 3,300 cycles at 1C rate, while Ah-level pouch cells exhibited a 10-fold improvement in cycle life.

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.

For the first time, Denmark is establishing production of microchip wafers at the leading standard. This makes Denmark a global player in chip production. The new “wafer factory,” which will be part of the University of Copenhagen, also gives a major advantage to Danish quantum researchers.

A study in National Science Review reports systematic observations of diazotroph abundance, community structure, and N₂ fixation rates in the western North Pacific. Using generalized additive models, the team characterized ecological niches of key cyanobacterial diazotrophs and quantified UCYN-B’s contribution to global N₂ fixation. The findings highlight UCYN-B’s pivotal role in marine N₂ fixation and provide new insights into ocean nitrogen cycle and productivity under climate change.
