Stereoreversed C–O Activation Unlocks All-Carbon Tetrasubstituted Z -Alkene Synthesis

Kaixin Chen, Jiali Peng, Jie Lin, Binjing Hu et autres

Stereochemically defined all-carbon tetrasubstituted alkenes are key structural motifs in various bioactive compounds and organic materials. Owing to the congested nature of the carbon–carbon double bond, controlling regio- and stereochemistry still remains a crucial challenge in modern synthetic chemistry. As such, we …

Interfacial anionic competition-driven electrochemical evolution in FeF3 conversion electrodes

Ziang Jiang, Shunrui Luo, Pengfei Wang, Jiali Peng et autres

Iron trifluoride demonstrates poor performance as a multi-electron conversion positive electrode in conventional ester-based electrolytes, yet exhibits higher capacity retention in ether-based electrolytes. This contrast has long remained unresolved in high-energy-density metal fluoride-lithium batteries. Here, we show that the electrolyte-dependent behavior originates …

High‐Sensitivity Perovskite γ‐Ray Detectors Enhanced by Device Engineering Toward Energy Spectroscopy Imaging

Ken Qin, Jiahe Zhang, Xue Gang Sun, Jiali Peng et autres

Abstract Perovskite‐based detectors for γ‐rays have emerged relatively recently and have attracted limited attention. Although increasing efforts are being directed towards their development, the absence of an adaptive processor, systematic theoretical framework, and various applications limit its further development. In this paper, …

Analysis of Potential Markers of Pork Freshness Based on Volatile Organic Compounds

Wu Wang, Yujing Wang, Yixin Zhang, Jiali Peng et autres

Bacteria and endogenous enzymes generate volatile organic compounds (VOCs), which are posited to be the primary source of undesirable flavors in spoilt pork. Headspace solid-phase microextraction–gas chromatography–mass spectrometry (HS-SPME-GC-MS) was employed to assess the fluctuations in VOC concentrations in pork stored under …

Band Tailoring Enabled Perovskite Devices for X‐Ray to Near‐Infrared Photodetection

Yichu He, Guan‐Hua Dun, Jun Deng, Jiali Peng et autres

Abstract Perovskite semiconductors have shown significant promise for photodetection due to their low effective carrier masses and long carrier lifetimes. However, achieving balanced detection across a broad spectrum—from X‐rays to infrared—within a single perovskite photodetector presents challenges. These challenges stem from conflicting …
