Sustainable Access to N ‐Heterocycles: One‐Pot Cascade Synthesis of Pyrroles From Bio‐Derived Furans

Haifeng Qi, Germán López Robledo, Jianglin Duan, Yujing Ren et autres

ABSTRACT The synthesis of pyrroles, fundamental nitrogen‐heterocyclic scaffolds in pharmaceuticals and materials science, remains a synthetic challenge, typically requiring pre‐functionalized precursors and multi‐step protocols. Here, we report an efficient cascade synthesis of N ‐substituted pyrroles directly from bio‐derived furans and nitroarenes, enabled …

RuCo Nanoalloy Catalysts Obtained From In‐Situ Reconstruction of High‐Entropy Oxides for Green Ammonia Synthesis

Xiuyun Wang, Jiahao Yu, Kailin Su, Yangyu Zhang et autres

ABSTRACT Optimizing promoters is crucial for designing efficient catalysts for ammonia (NH 3 ) synthesis under mild conditions. However, this endeavor is often hampered by a fundamental trade‐off: weak metal‐promoter interactions (MPI) lead to promoter segregation, while excessively strong ones block active …

Research on adaptive noise suppression methods in high-precision OFDR strain measurement

Qihao Zhang, Chen Guan, Haifeng Qi, Xibao Gao et autres

In this study, we proposed and experimentally validated a high-precision strain measurement method for optical frequency domain reflectometry (OFDR) based on enhanced adaptive median filtering method (AMF). As the OFDR system enhances measurement spatial resolution, the correlation between the reference signal and …
