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.

The University of Jyväskylä, Finland, has been involved as part of an international collaboration that has identified a way to completely suppress superconductivity in superconducting and ferromagnetic junctions. The results are key towards the development of non-volatile superconducting random access memories and could enable more energy-efficient information and communication technologies.
