Safracin B as a Synthetic Linchpin: From Natural Product to Drug Intermediate and Beyond

European Journal of Organic Chemistry, EarlyView.
Safracin B is employed as a key precursor for the streamlined preparation of cyanosafracin B and safracin A. Careful tuning of the reaction parameters affords these derivatives in high efficiency, and full nuclear magnetic resonance signal assignments are established for the complex safracin frameworks.

Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

FlexMat, EarlyView.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...

The research progress in polyethylene oxide polymer electrolytes

FlexMat, EarlyView.
Polyethylene oxide (PEO) has become the mainstream matrix material for solid polymer electrolytes (SPEs) due to its excellent lithium salt complexation ability and processability. However, its high crystallinity results in low ionic conductivity at room temperature and difficulty in suppressing lithium dendrite growth, which significantly hinders the ...
