Highly selective and active Cu-In2O3/C nanocomposite for electrocatalytic reduction of CO2 to CO

The CuIn2O3/C nanocomposite was prepared by a simple solid-phase reduction method. The introduction of In2O3 into Cu/C to form the CuIn2O3/C nanocomposite evidently enhances the electrocatalytic activity for the selective reduction of CO2 to CO. Specifically, the CuIn2O3/C nanocomposite exhibits higher Faraday efficiency (FE = 86.7%) at -0.48 V vs. the reversible hydrogen electrode (RHE) in the electrocatalytic reduction of CO2 to CO and larger current densities (55 mA cm(2)) under a low overpotential (-1.08 V vs. RHE). These indicate its superior performance over many of the reported Cu-based catalysts [1-4]. It was also found that by rationally adjusting the applied potential, tunable syngas can be formed, which can be used to synthesize formic acid, methyl ether, methanol, synthetic fuels, or other bulk chemicals through appropriate industrial processes. Furthermore, the CuIn2O3/C nanocomposite maintains good stability in the electrocatalytic reduction of CO2. This work demonstrates a novel strategy to convert CO2 into desired products with high energy efficiency and large current density under low overpotential by the rational designing of non-precious metal catalysts.

Experimental investigation on the effect of organic solvents on gas development of coalbed methane reservoir

CBM reservoirs are extremely vulnerable to damage due to their complex pore structure. So, changing pore structures in CBM reservoirs is of vital importance for reducing reservoirs damage. Organic solvents have been considered as additives into fracturing fluids to enhance production because they can enhance the pore connectivity and loosening macromolecular network structure. It is thus of great interests to investigate how organic solvents (ethanol and ethylene glycol ether) change micropore structures and fluid distribution. In this study, samples were selected from different wells completed in No. 3 coal seam, Zhaozhuang minefield. Low-pressure nitrogen adsorption (LP-N(2)GA) experiments were conducted on coal samples to evaluate the changes in pore-structure parameters including specific surface area (SSA), pore diameter, and pore volume. NMR experiments were conducted on coal samples to evaluate the changes in fluid distribution. Analyzing the LP-N(2)GA results suggests ethylene glycol ether and ethanol can effectively increase SSA, pore diameter, and opening degree of pores in coal samples. Comparative analysis of NMR results indicates that ethylene glycol ether consistently reduces the irreducible water saturation (S-wir) in samples. The average value of S-wir of raw samples is 0.8670 and the average value of S-wir of samples treated with ethylene glycol ether value is 0.7644. Considering the porestructure alterations, this study demonstrates that ethylene glycol ether is more preferable for enhancing recovery from CBM reservoirs compared with ethanol.

Modelling of performance, emission, and combustion of an HCCI engine fueled with fusel oil-diethylether fuel blends as a renewable fuel

The aim of this study is to model the HCCI engine performance and exhaust emissions characteristics fueled with fusel oil/diethylether fuel as a renewable fuel by employing the response surface method. The effect of independent variables -different concentrations of fusel oil/diethylether fuel, engine speed, and lambda value – on the response parameters including engine torque, BSFC, COV imep, MPRR, along with CO2, CO, NOx, and UHC were investigated and estimated by multi-regression models. To determine an optimal combination of engine working condition, the desirability function approach was used. High desirability of 82% was achieved at the diethyl ether ratio of 41.72%, the engine speed of 884 rpm, and the lambda value of 2.08. This engine working condition was recommended as the optimum response variables for the HCCI engine having 11.80 Nm of torque, 1.36% of COVimep, 3.14 of MPRR, BSFC of 268 g/kWh, CA10 of 7.52, and CA50 of 11. Besides, the optimal value for engine-out emissions was found to be 0 ppm for NOx, 243.11 ppm for UHC, 6.09 (%Vol.) for CO2, and 0.2 (% Vol.) for CO emissions. The outcomes of this study indicated that all multi-regression models developed by the RSM method could successfully estimate the variations of both engine performance indicators and exhaust emissions.

Pharmacological activity and flavonoids constituents of Artemisia judaica L aerial parts

Ethno-pharmacological relevance: Artemisia judaica L is an aromatic medicinal plant growing widely in Saint Katherine, Sinai, Egypt, and used in traditional medicine as a herbal remedy for antibacterial, anthelmintic, antidiabetic, analgesic and anti-inflammatory activities. Additionally, other Arabic regions commonly used it in their folk medicines for the treatment of fungal infections, atherosclerosis, cancer, diabetes, arthritis, and inflammatory-related diseases. Aim of the study: Based on the traditional medicinal uses of A. judaica, the present study was designed to validate some of the traditional uses as the analgesic, anti-inflammatory, antipyretic, hepatoprotective, antidiabetic, and antioxidant activities of 80% aqueous methanol extract (AME) of A. judaica aerial parts as well as isolation and identification of its flavonoid content. Materials and methods: AME of A. judaica aerial parts was fractionated using column chromatography and the structures of the isolated compounds were established using different spectroscopic data. Analgesic activity was evaluated using acetic acid-induced writhing in mice; antipyretic activity was assessed using yeast suspension-induced hyperthermia in rats; anti-inflammatory activity was evaluated using carrageenan-induced paw edema; the hepatoprotective effect was studied by measuring liver enzymes in carbon tetrachloride(CCl4)-induced hepatotoxicity rats while antidiabetic activity was estimated in alloxan hyperglycemia. Results: Eight flavone compounds namely luteolin 4′ methyl ether 7-O-beta-D-C-4(1)-glucopyranoside (1), 8-methoxyapigenin 7-O-beta-D-C-4(1)-galactopyranoside (2), isovitexin (3), 8 methoxyluteolin 7-O-beta-D-C-4(1)-glucopyranoside (4), diosmetin (5), cirsimaritin (6), luteolin (7), and apigenin (8) were identified from AME of A. judaica. The AME was found to be non-toxic to mice up to 5 g/kg b.w. Moreover, it exhibits significant analgesic antipyretic, anti-inflammatory, antidiabetic, hepatoprotective, and antioxidant activities in a dose-dependent manner. Conclusion: The AME was nontoxic; it exhibits significant analgesic, antipyretic, anti-inflammatory, antidiabetic, hepatoprotective, and antioxidant activities. Moreover, the isolated flavone was identified from AME for the first time.

First stable (Z)-configuration of cyanostilbene derivative: An effective turn-on fluorescent sensor for lysine in aqueous media

Due to the rapid E/Z isomerization of cyanostilbene under light or heating, the stable (Z)-configuration of cyanostilbene was hard to be obtained although many (E)-cyanostilbene derivatives had been reported as excellent fluorescence sensor. In this work, the first stable (Z)-configuration of cyanostilbene derivative (Z)-CS bridged by crown-ether chain was designed and synthesized under the irradiation of UV365 and heating. The stable (Z)-configuration was attributed to the short bridging crown-ether chain which restricted the E/Z isomerization of cyanostilbene. (Z)-CS exhibited the weak AIE effect in H2O/DMSO system, but showed the strong turn-on fluorescence enhancement after adding lysine. The detection limit of (Z)-CS for lysine attained 1.34 x 10(-7) M. The selective sensing behavior for lysine was stable in pH = 6-9 and was little interfered by other species. The 1:1 sensing mechanism was proposed by the investigation of Job’s plot, H-1 NMR and MS binding spectra. The sensing ability of (Z)-CS was successfully applied for analyzing lysine in urine samples of human body. (Z)-CS also displayed the good bioimaging performance with enhanced blue-purple fluorescence after detecting lysine. The work not only presented an effective fluorescence sensor for lysine in aqueous media, but also confirmed firstly the excellent application prospect of stable (Z)-configuration of cyanostilbene as fluorescence probe in complicated and living environment.

Microphase separation/crosslinking competition-based ternary microstructure evolution of poly(ether-b-amide)

The temperature dependence of the rheological properties of poly(ether-b-amide) (PEBA) segmented copolymer under oscillatory shear flow has been investigated. The magnitude of the dynamic storage modulus is affected by the physical microphase separation and irreversible crosslinking network, with the latter spontaneously forming between the polyamide segments and becoming the dominant factor in determining the microstructural evolution at temperatures well above the melting point of PEBA. From the rheological results, the initial temperature of the rheological properties dominated by the microphase separation and crosslinking (T-cross) structures were determined, respectively. Based on the two obtained temperatures, the microstructure evolution upon the heating can be separated into the ternary microstructure domains: homogenous (temperature below ), microphase separation dominating (between and T-cross), and crosslinking dominating domains (above T-cross). When the PEBA is heated to above T-cross, the content of crosslinking network increases with time and temperature, leading to an irreversible and non-negligible influence on the rheological, crystallization, and mechanical properties. A more pronounced strain-hardening phenomenon during the uniaxial stretching is observed for the sample with a higher content of crosslinking network.

Carbonyl- and thioether-linked cyanobiphenyl-based liquid crystal dimers exhibiting twist-bend nematic phases

A homologous series of ketone-type liquid crystal (LC) dimers, namely carbonyl- and thioether-linked cyanobiphenyl-based bent LC dimers (CBCOnSCB), with odd numbers of alkylene spacers (n = 3, 5, 7, and 9), was developed. CBCOnSCB dimers (n = 3, 5, and 7) formed a twist-bend nematic (N-TB) phase below the nematic (N) phase. The N to N-TB phase-transition temperatures of CBCOnSCB were higher than those of previously reported symmetric bis(thioether)-linked CBSnSCB and asymmetric ether- and thioether-linked CBOnSCB analogs. Compared to the vitrifiable CBSnSCB and CBOnSCB analogs, CBCOnSCB tended to crystallize. Single-crystal X-ray structural analysis of CBCO5SCB was also performed. (C) 2020 Elsevier Ltd.

A Comparative Study on the Extraction of Au(III) Using Cyclopentyl Methyl Ether, Dibutyl Carbitol, and Methyl Isobutyl Ketone in Acidic Chloride Media

Recently, a commercially available ethereal compound, cyclopentyl methyl ether (CPME) was found to act as an extractant for Au(III) in acidic chloride media. In this study, the extraction behavior of Au(III) using CPME was compared with commercial extractants dibutyl carbitol (DBC) and methyl isobutyl ketone (MIBK). The order of extractability for Au(III) was MIBK > DBC > CPME. The extraction capacity tests indicated that the extraction using the three extractants was unsaturated, and at least 0.30 mol/dm(3) (60 g/dm(3)) could be loaded onto the three extractants. The extraction selectivity for metal ions using the extractants was similar, but MIBK showed a lower metal selectivity. The extractability of CPME was relatively low compared with DBC and MIBK; however, CPME was advantageous in the stripping and reductive recovery of extracted Au(III). Gold was recovered quantitatively as metallic gold (Au(0)) by reduction using oxalic acid.

Influence of surface-modified glass fibers on interfacial properties of GF/PEEK composites using molecular dynamics

In this paper, molecular dynamics (MD) simulations are carried out to explore the influence of surface modification of glass fiber on interfacial binding energy and failure behavior of GF/PEEK composites. The silane coupling agent and sulfonated PEEK (SPEEK) are employed to modify the surface of glass fibers (GF), and the results reveal that the SPEEK can be employed as an adhesive sizing agent to improve the interfacial bonding strength of GF/PEEK composites. In addition, the synergistic mechanism of non-bonding and mechanical interlocking is investigated by using MD simulations. The interface shear simulation results demonstrate that the interfacial shear strength of composite increased and more resin molecules are found on the surface after SPEEK is incorporated into the GF surface. Moreover, compared with surface-untreated short GF-reinforced PEEK composite, the experimental results demonstrate that the tensile and bending strength of SGF/PEEK composite are improved after interface modification with SPEEK by 21.4% and 30.2%, respectively. The current study presents the utilization of MD simulation for interface design to enhance the mechanical properties of fiber reinforced PEEK composites.
