An acid-base bifunctional zeolitic imidazolate framework catalyst (ZIF8-A61-SO3H) with amine and sulfonic acid groups was successfully prepared through simple two step post-synthetic modification: preparation of aminefunctionalized ZIF-8 with amine contents of 61% (ZIF8-A61) by the ligand exchange of 2-mIM with 3-amino1,2,4-triazole (Atz), followed by the sulfonic acid functionalization by the ring-opening reaction of 1,3-propanesultone with -NH2 groups in ZIF8-A61. Amine-functionalized ZIF8-A materials with difference amine contents (15%, 34%, and 61%, respectively) were also prepared by controlling the synthesis time. All obtained ZIF catalysts evaluated as a heterogeneous catalyst for one-pot deacetalization-Knoevenagel condensation tandem reaction. Compared with ZIF-8 and amine-functionalized ZIF-8 catalysts, ZIF8-A61-SO3H catalyst showed good catalytic performance with 100% conversion of the reactant and 98% selectivity of the final Knoevenagel product. An enhanced catalytic activity can be attributed to the co-existence of site-isolated acid-base groups on the ZIF8-A61-SO3H catalyst in close proximity. The heterogeneous nature of the catalytic system was confirmed by a hot-filtering test and the catalyst also exhibited reusable in the five repeated cycles. A plausible catalytic mechanism of deacetalization-Knoevenagel condensation reaction over ZIF8-A61-SO3H was also proposed.

Oxidative stress biomarkers are powerful endpoints in toxicological research. Cellular reductive/oxidative balance affects numerous signaling pathways involving H2O2. Detoxification and control of H2O2 levels results mainly from catalase activity. The aim of this work was to develop a precise, simple, cost-effective microassay to measure catalase activity in small tissue samples and cell extracts. We developed a protocol that quantifies H2O2 decomposition by intrinsic catalase in biological samples. Catalase activity was calculated based on rate of decomposition of H2O2, following absorbance at 240 nm. We developed a multi-well spectroscopic approach, reducing sample quantity requirements and allowing simultaneous assessment of large number of samples. The protocol is sensitive across a wide range of catalase activity (11.5-7575 U). The assay presents a 95% confidence interval with an intra-assay coefficient of variation of 3.7%, an inter-assay coefficient of variation of 6.2% and good correlation with a commercial kit. The assay was established and validated for different biological samples, including sheep hepatic tissue and human tumor and non-tumor cell lines. This high-throughput method is robust, sensitive, time-saving and cost-effective, generating highly reproducible results with precision and good correlation with a commercial kit reinforcing the method’s validity for research and toxicological applications.

This article is focused on the preparation and characterization of functional nanosilica incorporated dental resins with better mechanical, cytotoxicity, sorption, and solubility properties. Silica nanoparticles were synthesized via Stober method and were functionalized with 3-amino-1,2,4-triazole. Dental nanocomposites were produced by embedding the functionalized nanosilica into bisphenol-A-glycidyl methacrylate/triethylene glycol dimethacrylate matrix to form B1-B6 series. This was achieved by mechanical mixing of the monomer (50:50 wt%), filler (10-60 wt%), initiator combination (CQ/EDMAB:O. 1 :0.4 wt%) and then followed by LED light curing (wavelength: 450-500 nm, power density:1000 mW cm(-2)) for 60 s. Fourier transform infrared spectroscopy, scanning electron microscopy, and thermogravimetric analysis techniques were used for characterization of the materials. Cytotoxicity tests were performed to evaluate cell viability and mechanical tests were done to check mechanical strength and stability of the materials. The mean sorption and solubility values of the materials were measured by making a series of experiments on different composite formulations.

A totally new theory of two-step stabilization mechanism for triazole-based zinc-containing complex (abbreviated as (Zn(ttr)(OAc)]) was proposed through several designed experiments. [Zn(ttr)(OAc)] strongly absorbed HCl at the beginning, and then broke down into 3-amino-1,2,4-triazole which could further stabilized PVC. The structure of [Zn(ttr)(OAc)] was characterized by FTIR spectroscopy, elemental analysis and SEM. Then, Congo red tests and discoloration tests verified [Zn(ttr)(OAc)] could absorb HCl effectively, but PVC showed poor initial whiteness, which further proved above -mentioned stabilization mechanism. Moreover, [Zn(ttr)(OAc)] combined with ZnSt(2) and dibenzoyl methane (DBM) effectively improved the initial color of PVC samples and provided PVC with shorter plasticizing time and longer dynamic thermal stability time than commercial stabilizer 1086F, confirmed by discoloration tests and dynamic thermal stability analysis. We believe [Zn(ttr)(OAc)]/ZnSt(2)/DBM stabilizer system can be used as a commercial stabilizer and the stabilization mechanism of [Zn(ttr)(OAc)] may provide a new way to stabilize PVC.

Treatment of 3-methylcyclohexanone with ethyl formate in the presence of sodium methoxide afforded sodium (2-methyl-6-oxocyclohexylidene)methanolate which reacted with aminopyrazoles, aminotriazole, and aminotetrazole to produce fused quinazoline derivatives; its reactions with cyanothioacetamide, cyanoacetamide, and cyanoacetohydrazide gave tetrahydroquinoline-3-carbonitrile derivatives. The reactions of 8-methyl-2-sulfanyl-5,6,7,8-tetrahydroquinoline-3-carbonitrile with alkylating agents led to the formation of thieno[2,3-b]quinoline derivatives. DFT computational studies of the synthesized compounds were carried out using B3LYP/6-311+G** and HF/6-311+G** approximations. The calculated HOMO and LUMO energies showed that charge transfer occurs in their molecules.

The interfacial design is critical in preparing high-performance mixed matrix membranes (MMMs), especially for the separation of larger sized components from mixtures. Herein, a facile and novel strategy was employed to design covalently linked zeolitic imidazolate framework-8-polydimethylsiloxane (ZIF-8@PDMS) MMMs without interfacial defects by a onestep synthesis route for ethanol recovery from ethanol aqueous solution. In this strategy, 3-glycidyloxypropyltrimethoxysilane (GOPTS) worked as the covalent linker of PDMS and amine-functionalized ZIF-8 nanoparticles (AZIF-8) simultaneously. The chemical structures and morphologies of AZIF-8 and AZIF-8@PDMS MMMs were demonstrated by various characterization techniques. The results exhibited that AZIF-8 and the MMMs were successfully prepared and AZIF-8 as the filler displayed better dispersion in the PDMS matrix and compatibility with the PDMS matrix as compared to ZIF-8 or GOPTS-modified ZIF-8 (GZIF-8). Therefore, AZIF-8@PDMS MMMs showed more excellent separation performance than ZIF-8 or GZIF-8-filled MMMs. In particular, AZIF-8@PDMS MMM with 7 wt % AZIF-8 loading exhibited the highest separation factor of 17.7 and a comparable total flux of 585.6 g/m(2) h at 40 degrees C with 5 wt % ethanol aqueous solution, which were improved by 176.6 and 34.5%, respectively, in comparison with the pristine PDMS membrane, breaking the trade-off effect between the flux and separation factor. This study might provide some new insights into the fabrication of high-performance MMMs for pervaporation recovery of various organic systems.

Eight novel chitosan derivatives bearing urea groups are designed and synthesized. Fourier transform infrared spectroscopy, H-1 nuclear magnetic resonance spectrometer, and elemental analysis are performed to confirm the structural characteristics of chitosan derivatives. The antioxidant activities, including superoxide radicals’ scavenging activity, 1,1-diphenyl-2-picrylhydrazyl radicals’ scavenging activity, and hydroxyl radical’ scavenging activity, of the derivatives are explored within different concentrations in the reaction system. In vitro fungicidal activity of these compounds is further tested against Fusarium oxysporum f. sp. niveum, Phomopsis asparagus, F. oxysporum f. sp. cucumebrium Owen, and Botrytis cinerea, respectively, particularly compounds exhibit significant control effect at 1.0 mg mL(-1). The experimental results indicate that the products bearing urea groups show enhanced antifungal property and antioxidant activity compared with pristine chitosan. Meanwhile, their bioactivities follow some regularity on the whole, that is, they are related to the electron-withdrawing property of the different substituted groups of urea. Derivatives with stronger electron-withdrawing property will have higher biological activities. L929 cells are used to carry out cytotoxicity test of chitosan and chitosan derivatives by Cell Counting Kit-8 assay. The results indicate that some of the samples show low cytotoxicity. This research will be helpful to broaden the application of chitosan in materials.
