The physicochemical properties were investigated by X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy, Temperature-Programmed Desorption, and sorption techniques. It was shown that the low pore tortuosity, hierarchical structure, and the reduction of the crystal size all can shorten the diffusion path and reduce the diffusion resistance, leading to the increase of propylene yield. By comparison, the propene yield increase to the increment of mesoporous volume due to the tortuosity is more effective than other aspects. For silica–alumina zeolites, the effective way to reduce the diffusion resistance and increase the selectivity of propylene is to lower the pore tortuosity degree, and then introduce the mesoporous structure and reduce the grain size.","PeriodicalId":15318,"journal":{"name":"Journal of Chemical Research-s","volume":"131 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86599652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The title complex crystallizes as a triclinic system with the P 1 ¯ space group and exists as an isolated tetranuclear complex. Numerous intermolecular hydrogen bonds and van der waals forces form a three-dimensional supramolecular network. Solid-state diffuse reflectance data show that there is a wide optical band gap of 2.91 eV. The solid-state photoluminescence spectrum reveals that the complex shows an up-conversion emission in the blue region of the light spectrum. Time-dependent density functional theory calculations reveal that this emission can be attributed to ligand-to-ligand charge transfer.","PeriodicalId":15318,"journal":{"name":"Journal of Chemical Research-s","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87199614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a separation and purification protocol is developed for perfectly separating an azeotropic mixture of allyl alcohol and water using the salting-out method, in which three potassium phosphate salts, K5P3O10, K3PO4, and K4P2O7, are systematically investigated as salting-out agents, and finally a product consisting of > 99% allyl alcohol is obtained. A thermodynamic study demonstrates that this process involves endothermy and increment entropy. There is a good correlation between the solubility of allyl alcohol and the molar concentration of salt (mol per 1 kg water), and the solubility of the allyl alcohol in the organic phase or the water phase can be forecast using the mass percentage of salts. This work provides a new methodology for the efficient separation of an azeotropic mixture of allyl alcohol and water.","PeriodicalId":15318,"journal":{"name":"Journal of Chemical Research-s","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74990093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, 16 phorbol derivatives were synthesized from phorbol, and their anti-leukemia activity against Jurkat, HL-60, and K562 were tested. The results showed that several derivatives had anti-leukemia activity, with 5B demonstrating the strongest cytotoxic activity against the K562 cell line (IC50 = 0.24 ± 0.04 μM). Based on the IC50 values, a structure-activity relationship was established. When the substituent contained an aromatic group, phorbol derivatives esterified with long-chain organic acids at three reactive hydroxyl groups (C12-OH, C13-OH, and C20-OH) had better activity. When aryl groups were absent from the substituent groups, phorbol derivatives esterified with short-chain organic acids at two hydroxyl groups had better activity. Derivatives esterified with heterocyclic acids, either tri-substituted or di-substituted, showed a significant decrease in cytotoxicity. The mechanism of anti-leukemia activity was explored through flow cytometry, which indicated that phorbol esters inhibited the growth of leukemia cells by inducing apoptosis, leading to cell death. Molecular docking data of compound 5B docking to PKCδC1B suggested that substituent groups should not be too large, and caution should be taken when substituting C20-OH. Overall, these findings provide valuable insights into the design of more effective phorbol esters as anti-leukemia agents, but further research is needed to confirm their safety and efficacy in clinical settings.","PeriodicalId":15318,"journal":{"name":"Journal of Chemical Research-s","volume":"52 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75558905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electrochemical interaction of anode material with lithium could produce an intercalation product, which could form the basis of a revolutionary battery system. Structural retention causes this reaction to proceed quickly and with a high degree of reversibility at room temperature. Titanium disulfide is one of the latest solid cathode materials.
