Photodynamic therapy(PDT)has emerged as a significant cancer therapy ***,cation-based organic small molecule aggregation-induced emission(AIE)photosensitizers(PSs)attract the wide atten-tion of many scientists,due to improved reactive oxygen species(ROS)production after ***,such PSs tend to localize only the mitochondria,limiting the death way of tumor cells(usu-ally apoptosis)during PDT process,which may affect the therapeutic effect under some ***,we designed a novel water-soluble three positive charge PS,TPAN-18F,which could be distributed uniformly in cell cytoplasm and had distribution in different sub-organelles(mitochondria,endoplasmic reticulum,lysosome).The experimental results showed that TPAN-18F-based PDT process can not only disrupt mitochondrial functions(reducing ATP production and destroying mitochondrial membrane po-tential),but also elevate the intracellular lipid peroxides(lPOs)level,which evoke the non-apoptotic death manner of tumor ***,in vivo studies showed that TPAN-18F-based PDT could effectively inhibit tumor ***,we believe that the construction of TPAN-18F is suggestive for tumor non-apoptotic therapy.

Several cyclopropanation catalysts for the synthesis of 3(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylates have been studied in this paper. Owing to electron deficiency of 1,1-dichloro-4-methyl-1,3-pentadiene, yield of this reaction is rather law compared with that of 2,5-dimethyl-2,4-pentadiene, Of all catalysts concerned. yield ranged from 25.1% to 47.2%.

A significant challenge in developing high-performance hybrid supercapacitors(HSCs)is the need to reasonably construct advanced architectures that consist of various components and exhibit superior electrochemical capacitance *** FeCoNi-layered double hydroxide(FeCoNi-lDH)porous material has a specific capacitance of 1960 F·g^(-1)when used as the anode material at 1 A·g^(-1).The FeCoNi-lDH material exhibits nanoplates with a distinct spindle morphology on their *** to the combined action of the three metals and abundant oxygen vacancies,they exhibit unique rate performance and cycle *** electronic structure of lDH and the regulation of oxygen vacancy were confirmed by density functional theory(DFT)*** suggests that the strength of hydroxide can reduce the energy required for oxygen vacancy formation in FeCoNi-lDH nanosheets and enhance ion and charge transfer,as well as electrolyte adsorption on the electrode *** FeCoNi-lDH//activated carbon(AC)HSC has an energy density of 53.2 Wh·kg^(-1)at a power density of 800 W·kg^(-1),surpassing other devices composed of comparable materials during the same *** study made significant advances in the design and synthesis of a ternary lDH porous structure with distinct oxygen vacancies,as well as its potential application in electrochemical energy storage.

Two kinds of residues,obtained from extraction of one weakly reductive coal,Shenfu-Dongsheng coal(SD),and one reductive coal,Pingshuo coal(PS),with sub-and supercritical water on a semi-continuous apparatus,were characterized by calorific value analysis and XPS analysis,and the combustion behaviors of residues were investigated by thermogravimetric *** results show that the residues have higher calorific value than raw coal samples,and SD residue has higher calorific value than PS residue.C-C,C-O and pyridinic nitrogen,pyrrolic nitrogen are the dominant form of C,O and N on the surface of raw coal samples and their extraction *** combustion behaviors of extraction residues show that the SD residue is more reactive and more easily burned than PS residue.
