Epilepsy is a clinical syndrome caused by highly synchronized abnormal discharges of neurons in the brain due to a variety of causes, and the clinical manifestations are characterized by seizures, transient, repetitive and stereotyped. Lipid droplets, as one of the important organelles in cells, have an important role in maintaining cellular functioning. Studies have shown that persistent epilepsy

Catalytic oxidative desulfurization performance of modified nano-sized β zeolite loaded with different structural polyoxometalates New J. Chem. (IF 3.3) Pub Date : 2024-04-10 Jinhong Li, Haonan Li, Zhimei Song, Ying Guo, Mengxiao Tai, Mei Han, Xinyao Wang, Lidong Chen, Dongmei Ren
The study of catalysts supported by polyoxometalates (POM) with green oxidative desulfurization activity is an important research topic in oil refining. In this paper, the nano-sized H-β zeolite support were modified by tetraethyl orthosilicate (TEOS) and tetrabutyl titanate (TBOT) to form the microporous-mesoporous structure. On this basis, the modified H-β zeolite was used as a support to load POM
