Unveiling the synergistic mechanism of Fe-Cu bimetallic catalysts for degradation of tetracycline antibiotic with ultralow peroxymonosulfate dosage consumption: Key contribution of electron transfer process.

Developing low-oxidant, high efficiency catalysts is critical to meet the green-circular goal in water treatments. Heteroatom-doped graphite-based carbon nitride carrier catalysts are among the most promising candidate materials in water purification catalysis. In this research, a bimetallic catalyst (Fe-Cu@SNC), featuring dual reaction centers, was prepared using a mass-producible co-precipitation method.

Dihydrochalcones from the leaves of .

Three new phlorizin derivatives, 6"--vanilloylphlorizin (), 6"--(4-hydroxybenzoyl)phlorizin (), 6"--feruloylphlorizin (), along with four known dihydrochalcones, phlorizin (), 3-hydroxyphlorizin, trilobatin, and 6"--acetylphlorizin were isolated from the leaves of . Their structures were established by analysis of extensive spectroscopic data. The new compounds were shown to be non-cytotoxic when tested against A549, HeLa, HepG2, and MCF-7 cell lines.
