Palladium imine-pyridine-imine complex immobilized on graphene oxide as a recyclable catalyst for the carbonylative homo-coupling of aryl halides

A heterogeneous 3-N,N,N-(II) Pd(OAc)(2) catalyst was prepared from the reaction of Pd(OAc)(2) with Si-Prn-N = C-Py-C = N-Prn-Si immobilized on graphene oxide (GO-Si-Prn-N = C-Py-C = N-Prn-Si-GO). The prepared catalyst was characterized by inductively coupled plasma optical emission spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, Raman spectroscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, UV-vis spectroscopy, BET surface area, scanning electron microscopy, transmission electron microscopy, and thermogravimetric analysis. The catalyst was employed as a heterogeneous catalyst for carbonylative homo-coupling of aryl iodides and bromides under carbon monoxide gas-free condition. Cr(CO)(6) was used as the carbon monoxide source and the desired symmetrical diaryl ketones were achieved in good to excellent yields. Moreover, the catalyst was reused up to five consecutive cycles without significant loss of activity.

Protective Effects of Nicotinamide Riboside on H2O2-induced Oxidative Damage in Lens Epithelial Cells

Purpose: To investigate the protective effects of nicotinamide riboside (NR) on oxidative damage in hydrogen peroxide (H2O2)-exposed human lens epithelial cell lines (SRA01/04) and the possible mechanisms underlying its protective effects. Materials and methods: SRA01/04 cells were divided into three groups: the control (CON) group, model (H2O2) group and treatment (NR+H2O2) group. Superoxide dismutase (SOD), catalase (CAT) and total glutathione (GSH) levels were detected to evaluate oxidative damage induced by different concentrations of H2O2 in SRA01/04 cells. After SRA01/04 cells were treated with NR and/or H2O2, cell viability was evaluated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and Hoechst staining, cell apoptosis was analysed using flow cytometry, reactive oxygen species (ROS) were measured with the DCFH-DA probe, and mitochondria were stained with MitoTracker to measure the mitochondrial membrane potential (MMP). In addition, western blotting was performed to detect the levels of proteins associated with apoptosis and related signalling pathways. Results: H2O2 induced oxidative damage in SRA01/04 cells by inhibiting the activity of SOD and CAT and reducing total GSH levels. Treatment of SRA01/04 cells with NR significantly increased cell viability and reduced cell apoptosis and ROS generation, whereas SOD and CAT activities and total GSH and MMP levels were improved by the NR treatment in an H2O2-exposed cell model. Furthermore, NR significantly inhibited the activation of the MAPK pathway but promoted activation of the JAK2/Stat3 pathway compared with the model group. Conclusions: NR may alleviate oxidative damage by targeting the MAPK and JAK2/Stat3 pathways in H2O2-treated SRA01/04 cells. NR may represent anovel drug for preventing or treating cataracts.

Surfactant-aided synthesis of RhCo nanoclusters as highly effective and recyclable catalysts for the hydrolysis of methylamine borane and dimethylamine borane

In the present study, the first ever and easy surfactant-aided synthesis of hexadecyltrimethyl ammonium bromide-stabilized RhCo nanoclusters (Rh0.63Co0.37@CTAB) and their employment as highly efficient, relatively cost-saving, and recyclable catalysts to generate hydrogen from the hydrolysis reactions of methylamine borane (MeAB) and dimethylamine borane (DMAB) are reported. The easy synthesis of Rh0.63Co0.37@CTAB nanoclusters is accomplished by synchronous reduction of appropriate rhodium and cobalt salts by sodium borohydride in the presence of CTAB as a surfactant in aqueous solution at room temperature. The Rh0.63Co0.37@CTAB nanoclusters are characterized by some techniques like ultraviolet-visible electronic absorption spectroscopy (UV-vis), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). They provide very remarkable turnover frequencies (TOFs) of 107.1 min(-1) and 142.9 min(-1) (8571.4 h(-1), best ever value) in the hydrolysis of MeAB and DMAB, respectively, even at very low temperatures. Their activation energies in the same reactions are calculated to be 55.3 kJ mol(-1) and 50.3 kJ mol(-1), respectively.

Atmospheric degradation mechanism of Z/E-CF3CF = CHCl, CF3CF = CCl2, and CF2 = CFCl initiated by OH radicals using a smog chamber with long-path FT-IR at 298 K

The products and mechanism for the OH-initiated reaction with the Cl-containing fluoroolefins Z/E-CF3CF = CHCl, CF3CF = CCl2, and CF2 = CFCl were investigated, using a smog chamber linked to a Fourier-transform infrared spectrometer. That Cl atoms were generated from Cl-containing fluoroolefin reactions with OH radicals was proven, and significant acceleration was observed during the experiments. The corresponding Cl-initiated reaction products were identified as CF3CFClC(O)H for Z/E-CF3CF =CHCl, CF3CFClC(O)Cl for CF3CF=CCl2, and CF2CIC(O)F for CF2 = CFCl. The influence of Cl-release on the kinetic study using the relative method was also discussed. Mechanisms for smog chamber reactions between Cl-containing fluoroolefins and OH radicals and Cl atoms, and their atmospheric degradation mechanisms, were proposed, based on the identification and quantification of detected products. Secondary atmospheric impacts from these products were also discussed.

First and Second Law Analyses of Double Effect Parallel and Series Flow Direct Fired Absorption Cycles for Optimum Operating Parameters

Thermodynamic analysis of double effect parallel and series flow direct fired absorption systems with lithium bromide-water has been carried out for different operating conditions. Temperatures in primary generator (T-g) and secondary generator (T-gs)/secondary condenser (T-cs) are optimized analytically using an iterative technique for maximum coefficient of performance (COP) and minimum energy required. A solution distribution ratio for a parallel flow cycle is also optimized. Source of energy used to drive the cycles is considered as compressed natural gas (CNG) and liquefied petroleum gas (LPG). Exergy destruction rate (EDR) in individual components as well as in the whole cycle along with volume flow rate of LPG and CNG is presented and compared. Results show that maximum COP for the parallel flow cycle is 3-6% higher than the series flow cycle. Also, minimum EDR of the parallel flow cycle is around 4% less while energy consumption is 2-3% low as compared to the series flow cycle.

Oxidized low-density lipoprotein accelerates the injury of endothelial cells via circ-USP36/miR-98-5p/VCAM1 axis

Circular RNAs (circRNAs) are a group of RNAs featured by a covalently closed continuous loop structure. This study aimed to uncover the function and mechanism of circ-ubiquitin specific peptidase 36 (USP36) in endothelial cells treated with oxidized low-density lipoprotein (ox-LDL). The levels of circ-USP36, microRNA-98-5p (miR-98-5p) and vascular cell adhesion molecule 1 (VCAM1) were examined by a quantitative real-time polymerase chain reaction (qRT-PCR). The viability, apoptosis and inflammation were detected by (4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, flow cytometry and enzyme-linked immunosorbent assay (ELISA), respectively. Western blot assay was performed to detect the expression of apoptosis and proliferation-related markers and VCAM1 protein level. The targets of circ-USP36 and miR-98-5p were searched using starBase website, and dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay were applied to validate the above predictions. Ox-LDL exposure induced the upregulation of circ-USP36 in HUVEC cells. Circ-USP36 accelerated ox-LDL-induced apoptosis, inflammatory and viability inhibition of HUVEC cells. MiR-98-5p was a direct downstream gene of circ-USP36. Circ-USP36 promoted the injury of ox-LDL-induced HUVEC cells through targeting miR-98-5p. VCAM1 could bind to miR-98-5p, and the protective effects of miR-98-5p accumulation on ox-LDL-induced HUVEC cells were reversed by the transfection of VCAM1. VCAM1 was regulated by circ-USP36/miR-98-5p signaling in HUVEC cells. Ox-LDL promoted the apoptosis and inflammation but suppressed the viability of HUVEC cells through upregulating circ-USP36, thus elevating the expression of VCAM1 via miR-98-5p.

Thermodynamic modeling of the MBr-BaBr2 (M = Alkali metals) systems

The complete thermodynamic optimizations of MBr-BaBr2 (M = Li, Na, K, Rb, Cs) systems were performed based on thermodynamic principles using CALPHAD approach. In this work, the existence of BaBr2-based solid solubility was firstly evaluated according to the corresponding liquid curves in available literature by the limiting liquidus slope equation and ideal liquid curve. The liquid enthalpy of mixing for LiBr-BaBr2 binary system was calculated via empirical prediction method. The Gibbs energy of liquid molten mixtures were modeled by the substitutional solution model (SSM) and the associate solution model (ASM), while that of the double salts were processed into stoichiometric compounds based on the Neumann-Kopp technique. The thermodynamic database with a series of thermodynamic properties and phase equilibria data of investigated systems were successfully established by optimizing model parameters. The simulated results could provide theoretical guidance and technical support, as well as applying in the design for the multi-components eutectic materials by combination with the binary alkali metal bromide systems.

Novel poly (ionic liquid)-based anion exchange membranes for efficient and rapid acid recovery from industrial waste

Owing to the less energy consumption, positive impact on the environment, and prospect of providing clean water resources, anion exchange membranes (AEMs) are promising materials for acid recovery from various industrial wastewater/effluent. Based on the diffusion dialysis process, AEMs selectively allow rapid proton permeation while efficiently retaining metal ions. To enhance the efficiency of the acid recovery process, precise control of macromolecular architecture and chemical composition that enables high hydrophilicity, proton conductivity through the membrane, and ion exchange capacity is required. In this direction, we report on the one-step fabrication of novel poly (ionic liquids)-based AEMs by the free radical polymerization of 1-butyl-3-vinyl imidazolium bromide, acrylic acid, styrene, and acrylonitrile under sunlight. The effect of monomer composition in an AEM matrix on the structural, physicochemical, surface, thermal, and proton conductivity is investigated. The experimentally determined acid dialysis coefficient (U-H+) obtained with synthesized poly (ionic liquid) based membranes PILM-1 and PILM-2 were 7.3 +/- 2 and 9.2 +/- 2 mh(-1) at room temperature (25 degrees C), while separation factors (SF) were 88.9 +/- 3 and 50.1 +/- 2, respectively. Both the U-H+ (> 700 times) and SF (> 4 times) are significantly values higher compared to the commercial AEM DF-120 (0.009 mh(-1) and 18.8 for U-H+ and SF, respectively). Thus, this study demonstrates the potential of the prepared AEMs as an alternate to deliver cost-effective, scalable, and rapid acid recovery compared to the currently existing technology.
