Catalytic ozonation of emerging pollutant and reduction of toxic by-products in secondary effluent matrix and effluent organic matter reaction activity

In this study, the performance of LaCoO3 (LCO) catalytic ozonation was evaluated comprehensively, including the degradation efficiency of benzotriazole (BZA) as a typical emerging pollutant, toxic bromate reduction and the disinfection by-products (DBPs) precursors removal ability in effluent organic matter (EfOM), as well as EfOM reactive activity in catalytic ozonation. Additionally, the reduction of toxic halogenated by-products in (catalytic) ozonation was reported, which was not focused on previous researches before. Results showed that LCO catalytic ozonation improved the removal efficiency of BZA, UV254 and SUVA via enhanced HO. formation. Interestingly, LCO catalytic ozonation showed the ability on the reduction of aldehydes and toxic halogenated organic by-products. Moreover, the formed [trichloromethane (TCM)], [bromochloroacetonitrile (BCAN)] and [dichloroacetamide (DCAcAm)] decreased significantly in catalytic ozonation. Catalytic ozonation was also able to remove DBPs precursors to decline the formation of DBP5, such as TCM, bromodichloromethane (BDCM), trichloroacetonitrile (TCAN) and trichloronitromethane (TCNM). This process was involved in the transformation of EfOM in catalytic ozonation, which was confirmed by multi-spectrum methods, two-dimensional correlation spectroscopy (2D-COS) and hetero-spectral 2D-COS. In summary, LCO was shown to be an effective catalyst to improve the performance of the sole ozonation on the removal of emerging contaminants and DBP5 precursors, as well as toxic by-products reduction. Additionally, the strategy of toxic by-products reduction in catalytic ozonation was proposed. Results indicated this technology was an important contribution on removal of refractory organics and formation of toxic by-products in water supply and wastewater treatment industry.

Electroreductive Carbofunctionalization of Alkenes with Alkyl Bromides via a Radical-Polar Crossover Mechanism

Electrochemistry grants direct access to reactive intermediates (radicals and ions) in a controlled fashion toward selective organic transformations. This feature has been demonstrated in a variety of alkene functionalization reactions, most of which proceed via an anodic oxidation pathway. In this report, we further expand the scope of electrochemistry to the reductive functionalization of alkenes. In particular, the strategic choice of reagents and reaction conditions enabled a radical-polar crossover pathway wherein two distinct electrophiles can be added across an alkene in a highly chemo- and regioselective fashion. Specifically, we used this strategy in the intermolecular carboformylation, anti-Markovnikov hydroalkylation, and carbocarboxylation of alkenes-reactions with rare precedents in the literature-by means of the electroreductive generation of alkyl radical and carbanion intermediates. These reactions employ readily available starting materials (alkyl halides, alkenes, etc.) and simple, transition-metal-free conditions and display broad substrate scope and good tolerance of functional groups. A uniform protocol can be used to achieve all three transformations by simply altering the reaction medium. This development provides a new avenue for constructing Csp(3)-Csp(3) bonds.

Doctor Gachet, in the kitchen, with the foxglove

Vincent van Gogh (1853-1890) is one of the most famous artists in the world. During his 10-year career as an artist, he created more than 850 paintings. These works of art are now displayed in museums around the globe. It is therefore even more surprising that van Gogh sold just one painting during his lifetime. Van Gogh is also well-known for his mental illness. In 1888, at the age of 35, he famously sliced off his left ear. This was followed by multiple mental collapses in early 1889, leading to his admission to a mental hospital. Despite living in the asylum, van Gogh continued to paint and created some of his most beautiful works of art during the year at Saint-Remy. Tragically, he committed suicide in 1890 at the age of 37. Over the 130 years since his death, there has been much speculation about the underlying illness of Vincent van Gogh. Many of his contemporary physicians felt that he had a form of epilepsy as the cause of his sudden attacks. By the last quarter of the 19th century, science and medicine were moving rapidly forward, and there were many medical conditions that had effective treatments. One example is the use of digoxin for the treatment of heart failure, and another is the discovery of potassium bromide for seizures. This paper provides an overview of van Gogh’s mental illness, the treatments that were offered by his contemporaneous physicians, and the role that these factors may have influenced his paintings.

Ceria nanorod supported gold nanoparticles as structured catalysts for the oxidative steam reforming of methanol: Effect of CTAB concentration on physiochemical properties and catalyst performance

Ceria (CeO2) supports were synthesized by hydrothermal treatment with different Cetyltrimethy-lammonium bromide (CTAB) concentrations (CeO2-X: 0.135, 0.270, 0.540 and 1.080, where X is the CTAB concentration in mmol). The micro-structures of bundle-like ceria nanorods (NR) were produced by thermal treatment of the crystalline Ce(OH)CO3 precursor. The exposed crystal planes of (200) and (111), corresponding to the d-spacing of 0.27 and 0.31 nm, were confirmed by high resolution transmission electron microscopy (HR-TEM). The fundamental characteristics of CeO2-0.135 led to the highest surface area, surface area normalized reducibility and oxidized gold species (Aun+/Au-0) on the surface, relatively higher oxygen vacancies and a smaller average gold particle size (7.9 nm). The activity results show that the Au/CeO2-0.135 has the highest methanol conversion and H-2 production rate for oxidative steam reforming of methanol (OSRM). The reducibility and gold particle size played a crucial role in determining the H-2/CO2 ratio at the temperature of 200 degrees C. (C) 2020 Elsevier Inc. All rights reserved.

Supercapacitive Performance of Surfactants Wrapped KIT-6/MCM-48 Templates Based Mesoporous Co3O4

In this paper, KIT: Korea Advanced Institute of Science and Technology No. 6 (KIT-6) and MCM: Mobil Composition of Matter No. 48 (MCM-48) mesoporous silica templates were prepared by wrapping Pluronic (P-123) and Cetyl trimethyl ammonium bromide (CTAB). Mesoporous Co3O4 geometry tailored KIT-6 and MCM-48 with different porosity were synthesized via reflux technique. Crystal geometry, morphology, molecular vibrations and pore structure were analyzed by X-Ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy and Brunauer-Emmett-Teller (BET) method based N-2 adsorption-desorption for the modified materials. As expected, MCM-48 micropore-dominated electrode exhibited higher specific capacitance (442.5 F/g) which is much superior to that of KIT-6 ( 88.9 F/g). Outstanding electrochemical execution is due to the mesoporous tailored architecture (average pore diameter of 6.1 nm) and synergistic contribution of MCM-48 architectured with a Co3O4 core. This promising electrode material opens up a new platform for high-performance supercapacitors.

Preparation of zein nanofibers with cinnamaldehyde encapsulated in surfactants at critical micelle concentration for active food packaging

This work studied the effect of nonionic surfactant (Tween 80), anionic surfactants sodium dodecyl sulfate (SDS), cationic surfactants sodium cetyltrimethyl ammonium bromide (CTAB), amphoteric surfactant (Lecithin) on the characteristics of electrospun zein nanofibers and on the release of cinnamaldehyde essential oil (CEO) in zein nanofibers. The effect of applying nanofibers as an antibacterial package was also investigated. Scanning electron micrographs demonstrated that the flat shape of zein nanofibers could shift to round when surfactants were added. The interaction between zein and lecithin caused many granules while the addition of other surfactants produced a smooth surface. Fourier transform infrared indicated that the addition of surfactants could change the secondary structure of zein. The addition of CTAB to zein nanofibers decreased the release of CEO while addition of Tween80, lecithin and SDS accelerated release in ethanol aqueous solution. The nanofibers inhibited the growth of microorganisms and prolonged the shelf life of mushrooms, which confirmed that it can be applied in active antibacterial package.

MiR-141 promotes cell proliferation and invasion in non-small cell lung cancer by targeting KLF9

OBJECTIVE: Non-small cell lung cancer is the cancer with the highest mortality rate in the whole world. MicroRNA-141 (miR-141) has been reported to be an abnormal expression in multiple tumors including in non-small cell lung cancer. The aim of this study was to verify the potential roles of miR-141 in non-small cell lung cancer and evaluate the effects on cell proliferative and invasive abilities. PATIENTS AND METHODS: MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) and transwell assays were conducted to calculate the tissues and cell lines’ proliferative and invasive abilities. Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) and Western blotting were utilized to evaluate the mRNA and protein levels of specific genes. RESULTS: MiR-141 was significantly upregulated, while kruppel-like factor 9 (KLF9) downregulated in non-small-cell lung cancer (NSCLC) tissues and cell lines. MiR-141 and KLF9 mRNA levels had a negative correlation in NSCLC tissues. The overexpression of miR-141 promoted the proliferation and invasion of A549 cells, while caused contrast results when knockdown miR-141. In addition. KLF9 was a direct target gene of miR-141 and KLF9 partially reversed the roles of miR-141 in A549 cells. MiR-141 promoted the proliferation and invasion by binding to KLF9 in NSCLC. CONCLUSIONS: MiR-141 promoted the proliferation and invasion by targeting the KLF9 in nonsmall cell lung cancer, and the newly identified miR-141/KLF9 axis provides novel insight into the pathogenesis of non-small cell lung cancer.

High photocatalytic activity of light-driven Fe2TiO5 nanoheterostructure toward degradation of antibiotic metronidazole

Monodispersed Fe2TiO5 nanoheterostructure was prepared via simple surfactant-assisted sol-gel method using cetyltrimethylammonium bromide (CTAB). After quantitative and qualitative analysis of nanostructures, simulated light-driven performance of Fe2TiO5 thin film as heterogeneous photocatalyst toward photodegradation of antibiotic metronidazole was investigated and compared with its forming metal oxides. Results showed the highest photocatalytic activity for Fe2TiO5 after 2h of irradiation by which the pseudo first-order photodegradation reaction of metronidazole leads to water and carbon dioxide production. Increase the photocatalysis efficiency based on Fe2TiO5 photocatalyst relative to TiO2 and Fe2O3 is due to lower mean size, more uniform distribution of nanoparticles and consequently an increase in the surface area available for the photocatalytic reaction, also the two metal centers arrangement in one structure that were resulted in effective light harvesting and enhancing the probability of reduction-oxidation reactions owing to fast transferring of charge carriers to surface with promoting separation and limiting recombination.

Nickel-Catalyzed Directed Cross-Electrophile Coupling of Phenolic Esters with Alkyl Bromides

Herein, we demonstrate the successful use of robust phenolic esters as an electrophilic acyl source in the reaction with diverse primary and secondary unactivated alkyl bromides. The cleavage of the relatively inert C-O bond is facilitated by the neighboring coordinating hydroxyl or sulfonamide moiety.
