Scientists have developed an AI-powered multi-agent system, named eNRRCrew, to tackle the challenge of producing sustainable ammonia. By automatically mining and analyzing over 2,300 scientific papers, this AI "crew" built a massive database and used it to identify key factors for designing efficient catalysts. The system can predict catalyst performance, recommend novel materials, and has already proposed a promising candidate that was validated by computational simulations and experiments. This AI-driven approach offers a new paradigm for accelerating scientific discovery in catalysis and beyond.

As an important quantum communication protocol, quantum teleportation has broad applications in quantum information science and technology. Toward the application, it is essential to enhance the ability of quantum teleportation by teleporting multiple quantum states simultaneously. Recently, the group led by Xiaolong Su at Shanxi University presents controllable deterministic quantum teleportation of multiple sideband qumodes simultaneously with the assistance of continuous-variable quantum entanglement. They show that the number of teleportable sideband qumodes in continuous-variable quantum teleportation are controllable by tuning the phase of the classical channel. The work presents a novel method for quantum teleportation of multiple quantum states simultaneously and take a crucial step in enhancing the teleporting ability of quantum teleportation.

Chinese researchers have developed China's first compact high-temperature superconducting magnetoplasmadynamic thruster, achieving a revolutionary reduction in power consumption from 285 kW to under 1 kW and weight from 220 kg to 60 kg. Published in National Science Review, the breakthrough utilizes YBCO superconducting material operating at liquid nitrogen temperatures (-196°C) to replace traditional copper coils. The thruster demonstrates an exceptional specific impulse of 3,265 seconds at 12 kW input power—more than ten times higher than conventional chemical propulsion. The team also established a comprehensive analytical magnetohydrodynamic model that accurately predicts performance parameters. This advancement solves the critical propulsion bottleneck for small satellites, enabling lightweight, cost-effective spacecraft with dramatically reduced fuel requirements for deep space missions.

A large-scale synchronized observation across 37 cities in North China Plain reveals a critical transition in urban ozone formation mechanisms, from predominantly VOC-limited regime to VOC–NO_x co-limited regime. This finding indicates that China’s ozone control efforts have passed through the most challenging phase, in which NO_x reductions tended to exacerbate ozone pollution. Further reductions in both NO_x and VOC emissions are now expected to be broadly effective, offering greater flexibility, feasibility, and optimism for future ozone mitigation in China.

Tokyo, Japan – Researchers from Tokyo Metropolitan University have created a new molecule which carries DNA into biological cells, to treat or vaccinate against illnesses. Many existing options rely on molecules with a strong positive charge, which can cause harmful inflammation. The team overcame this by using a neutral molecule and a new method to bind DNA to it, making it possible to deliver DNA into cells. Successful experiments in mice promise new, more effective therapies.

Professor Chao Wang's team at Tianjin Normal University recently reported a non-covalent C–H⋯π interaction-based olefin functionalization strategy, achieving highly regio- and enantioselective1,2-borylalkynylation reactions of unactivated alkenes. Utilizing the weak interaction between the aryl side arm of the chiral diamine ligand andthe π-donor group of the olefin substrate, they successfully achieved precise three-component coupling of the olefin, B₂pin₂, and alkynyl bromide under nickel catalysis. The study achieved efficient construction of remote chiral centers by controlling the transition state of migration insertion through non-covalent interactions. This strategy eliminates the dependence on traditional covalently directed groups, complementing existing covalently directed models and opening up new avenues for site- and stereoselective bifunctionalization of unactivated alkenes. The article was published as an open access Research Article in CCS Chemistry, the flagship journal of the Chinese Chemical Society.
