Ruthenium catalysts supported on zinc-promoted amorphous-niobium mixed oxides were prepared, characterized, and studied in the additive-free partial hydrogenation of benzene reaction. The amorphous matrix of Nb2O5 was responsible for a highly active Ru/Nb2O5 catalyst, although less selective than those containing zinc. The ZnO-containing supports were prepared by wet impregnation technique, followed by incipient wetness of ruthenium chloride salt. The catalysts were characterized by textural analysis, X-ray fluorescence, X-ray diffraction, H-2 chemisorption, temperature-programmed reduction (TPR), Scanning electron microscopy, H-2 temperature-programmed desorption, and X-ray photoelectron spectroscopy (XPS) of the calcined-reduced samples. Chlorine retention was observed on zinc-containing samples. An unexpected ZnNb2O6 oxide phase, ascribed to a selectivity increase with less activity loss, was obtained for the supports at lower temperatures than those related on the literature. A very complex electronic environment of Ru- and Zn-containing species interactions was observed by TPR. The presence of surface-reduced (Ru-0) and partially reduced (Ru delta+) Ru species observed by XPS justified well, respectively, the activity and selectivity achieved with every catalyst. The addition of water as a solvent resulted in very constant yield to cyclohexene, as expected, despite activity diminution due to low solubility of the reactants. (C) 2020 Elsevier Ltd.

Deicing agents are used to dissolving the frost on road surfaces in winter and cold areas. Researchers have evaluated the impact of different deicing agents on the moisture susceptibility performance of asphalt mixtures, but they have not investigated the effect of these agents on fatigue failure and thermodynamic parameters of asphalt mixtures. Therefore, in this research, by investigating the effect of two new deicing agents of calcium magnesium acetate (CMA) and potassium acetate (PA) as well as sodium chloride (NaCl) traditional agent on moisture and fatigue performances of asphalt mixtures, predictive model of the tensile strength ratio (TSR) and the fatigue life ratio (NFR) using genetic programming (GP) based on the surface free energy (SFE) components and other properties of asphalt mixtures were presented. Nano hydrated lime (NHL) was applied as an asphalt binder modifier and an anti-stripping agent to improve the strength of asphalt mixtures. The results indicated that the saturated mixtures in CMA had the highest indirect tensile strength (ITS) and fatigue life in lower freeze-thaw cycles, while the NaCl-saturated samples had more ITS and fatigue life in higher cycles. The CMA-saturated samples had the greatest TSR and NFR. Using NHL in all saturated samples resulted in increasing TSR and NFR values. Results of SFE method showed that using NHL increased the polar, non-polar and basic components of asphalt binders and decreased their acidic components. Also, using NHL increased the total SFE amount of asphalt binder, enhancing the adhesion of aggregate and asphalt binder and cohesion in asphalt binder membrane, and as a result, improving the moisture resistance in asphalt mixtures. Using 1.5% NHL had the greatest effect on improving adhesion free energy (AFE), cohesion free energy (CFE) and detachment energy (DE). Among deicing solutions, CMA had the highest CFE, in general, and NaCl had the best DE val-ues. PA-saturated samples had the greatest permeability of asphalt mixture (PAM) values. GP model had a high R-2 96.4% and 98.3% for TSR and NFR, respectively. Using GP model to achieve the maximum TSR and NFR, the Pareto curve showed that 1.32% NHL was the optimum value for simultaneously increasing moisture resistance and fatigue life.

In the present work, the new organic-inorganic hybrid material (C5H8N3)(C5H9N3)BiCl6 was elaborated by halobismuthates as building units and 3,4-diaminopyridinium organic cations. The title compound is crystalized at room temperature by slow evaporation in the monoclinic space group P2(1)/n with the following parameters a = 7.197 (2)angstrom, b = 23.106 (9)angstrom, c = 11.780 (5)angstrom, beta-96.443 (3)degrees Z = 4 and V = 1946.5 (12)angstrom(3). The structure is built up of separated BiCl63- octahedral chlorine coordination and two molecules of 3,4-diaminopyridinium with two different protonation sites aminopyridine (one is mono-protonated and the other is di-protonated), which are linked via N-H center dot center dot center dot Cl hydrogen bonds forming a zero dimensional network. The atomic arrangement can be described as an alternation of organic and inorganic layers. Besides, the nature of the distortion of the inorganic polyhedral has been studied and can be attributed to the stereo activity of the Bi(III) lone electron pair. The infrared IR and Raman studies were recorded in the 4000-400 cm(-1) frequency region and the Raman spectra was recorded in the external region of the anionic sublattice vibration 500 -50 cm(-1). The thermal decomposition of precursors studied by differential scanning calorimetry (DSC), confirms the degradation of the title compound around 135 and 137 degrees C. The photoluminescence spectrum exhibits two strong bands of luminescence located at 377 and 580 nm which are attributed to the band-to-band and exciton emissions within the chlorobismuthate inorganic part, respectively.

Knowledge of speciation and thermodynamic properties for aqueous gold complexes are important for both the understanding and numerical modelling of the formation of hydrothermal gold deposits. While gold speciation in chlorine- and sulfur-rich hydrothermal fluids has been investigated by considerable theoretical and experimental studies, the complexation of gold with other ligands that may be important for transporting gold in hydrothermal fluids, such as hydroxyl (OH-) and ammonia (NH3) complexes, have received limited attention so far. In this study, we conduct ab initio molecular dynamics (MD) simulations to calculate the coordination structures of Au(I)-OH and Au(I)-NH3 complexes. Our simulations show linear structures of Au(I) complexes with two bonded ligands (OH-/NH3/H2O), consistent with previous experimental and theoretical studies of Au(I) complexation (e.g., Liu et al., 2014). The new speciation models show that Au(I)-OH-/NH3/H2O complexes are stable in hydrothermal fluids and vapors. We also use thermodynamic integration to determine the formation constants of these species at temperatures up to 350 degrees C and at water-saturated pressures; furthermore, we extrapolate these properties to wider temperatures and pressures range based on the Modified Ryzhenko-Bryzgalin equation of state parameters. In particular, this study, for the first time, reports the speciation and formation constants of mix-ligand [Au(NH3)(OH)]((aq))(0) complexes. The derived formation constants show that the stability of Au(I)-NH3 complexes decreases progressively with increasing temperature. The quantitative modelling of gold solubility based on the new thermodynamic data shows that gold can be transported as Au(I)-OH-/NH3 complexes in sulfur-poor and ammonia-rich hydrothermal fluids. In sulfur-bearing ore fluids, ammonia is only likely to transport small amounts of gold as [Au(NH3(OH)]((aq))(0)in hydrothermal fluids in the near-neutral to alkaline fluids under extremely reduced conditions.

A sensitive and selective amperometric determination method for isoniazid (INZ), an anti-tuberculosis drug, was studied by cyclic voltammetry and chronoamperometry, using carbon doped vanadium trioxide @ Prussian blue modified graphite felt electrodes (V2O3-C@PB/GF). V2O3-C was synthesized by a solvothermal technique and fixed on GF; then PB was generated on the so-obtained V2O3-C/GF. The morphology and structure of the composite electrode were characterized via X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR) spectroscopy and ultraviolet-visible (UV-vis) spectroscopy. After optimization of the parameters influencing the formation of V2O3-C@PB/GF, the composite electrode showed efficient electrocatalytic performance for isoniazid detection in 0.5 M potassium chloride (KC1) solution. A wide linear concentration range (2.5 x10(-)(9)-1.1 x10(-3) M), a good sensitivity (1.378 AIM, 0.561 ABM) and a low detection limit (0.83 nM) were obtained. Furthermore, long-term stability and fabrication reproducibility of the electrochemical device have been investigated, as well as its robustness to interferent species. Finally, the practical applicability of the proposed sensor was assessed by detecting INZ in commercial tablets, bovine serum albumin and human urine samples: recovery values varied from 96.8% to 105.2%, indicating an excellent analytical performance for INZ qualification.

Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 1119-46-6, Name is 5-Chloropentanoic acid, SMILES is O=C(O)CCCCCl, in an article , author is Zhang, Hangjing, once mentioned of 1119-46-6, Product Details of 1119-46-6.

Conductive smart hydrogels with several virtues such as similar characters to biological tissues, sensitive response to ambient variations, have shown their excellent talents in the field of flexible electrical sensors, biomedical devices and directional transportation. However, complex preparing approaches or the instable inner structures have not only been time-consuming, but also broken up the performance and reliability of the smart hydrogel-based devices. In this work, a facile one-step method is put forward to synthesize a kind of conductive poly(N-isopropylacrylamide) (PNIPAM) hydrogel doped by a new green solvent of deep eutectic solvent (DES) containing choline chloride (ChCl) and acrylic acid (AA). Through the copolymerization of AA and NIPAM, the mechanical strength of the DES-doped PNIPAM hydrogels is drastically improved compared to the pure PNIPAM gels, and some doped hydrogels lost the typical phase transition temperature of PNIPAM. Moreover, due to the ionic property of DES, the hybrid hydrogels also present the thermal-depending conductivity as well as sensitive deformation response, which can be used as a smart switch in a circuit or a sensing element with environmental response ability. The cost-effective preparation and the attractive performance of the DES-doped hydrogels offer a new avenue to construct multi-functional materials.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 1119-46-6, you can contact me at any time and look forward to more communication. Product Details of 1119-46-6.

In this paper, the simple and low-cost water extraction way was used to acquisition Betel leaves extracts (BLE). The water as the extraction solvent has the characteristics of low price, environmentally friendly, and good solubility for other extraction solvents. BLE was researched as an environmental-friendly inhibitor via various experimental methods and theoretical calculations. Electrochemical experiments manifest that BLE can restrain reactions of the cathode and anode of Q235 steel. The BLE concentration was 400 mg/L, the anti-corrosion efficiency was close to 94%. The experimental data show that BLE can show high-quality anti-corrosion nature for Q235 steel immersing in 1 M hydrochloric acid (HCl) environment at a certain temperature range. The morphology maps of scanning electron microscope (SEM) and atomic force microscopy (AFM) strongly proves the data of electrochemical experiments. In addition, the BLE adsorption at the Q235 steel surface belongs to the Langmuir mono-layer adsorption. Quantum chemical calculations (QCC) and molecular dynamics simulations (MDS) effectually manifest that BLE can show decent anti corrosion character. (C) 2020 Elsevier Inc. All rights reserved.

Background. Ischemic stroke is a severe acute cerebrovascular disease which can be improved with neuroprotective therapies at an early stage. However, due to the lack of effective neuroprotective drugs, most stroke patients have varying degrees of long-term disability. In the present study, we investigated the role of exosomes derived from CXCR4-overexpressing BMSCs in restoring vascular function and neural repair after ischemic cerebral infarction. Methods. BMSCs were transfected with lentivirus encoded by CXCR4 (BMSCCXCR4). Exosomes derived from BMSCCXCR4 (Exo(CXCR4)) were isolated and characterized by transmission electron microscopy and dynamic light scattering. Western blot and qPCR were used to analyze the expression of CXCR4 in BMSCs and exosomes. The acute middle cerebral artery occlusion (MCAO) model was prepared, Exo(CXCR4) were injected into the rats, and behavioral changes were analyzed. The role of Exo(CXCR4) in promoting the proliferation and tube formation for angiogenesis and protecting brain endothelial cells was determined in vitro. Results. Compared with the control groups, the Exo(CXCR4) group showed a significantly lower mNSS score at 7 d, 14 d, and 21 d after ischemia/reperfusion (P<0.05). The bEnd.3 cells in the Exo(CXCR4) group have stronger proliferation ability than other groups (P<0.05), while the CXCR4 inhibitor can reduce this effect. Exosomes control (Exo(Con)) can significantly promote the migration of bEnd.3 cells (P<0.05), while there was no significant difference between the Exo(CXCR4) and Exo(Con) groups (P>0.05). Exo(CXCR4) can further promote the proliferation and tube formation for the angiogenesis of the endothelium compared with Exo(Con) group (P<0.05). In addition, cobalt chloride (COCl2) can increase the expression of beta-catenin and Wnt-3, while Exo(Con) can reduce the expression of these proteins (P<0.05). Exo(CXCR4) can further attenuate the activation of Wnt-3a/beta-catenin pathway (P<0.05). Conclusions. In ischemia/reperfusion injury, Exo(CXCR4) promoted the proliferation and tube formation of microvascular endothelial cells and play an antiapoptotic role via the Wnt-3a/beta-catenin pathway. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

For the first time, the UIO-66, NH2-UIO, and NH2-UIO particles covalently functionalized by Glycidyl Methacrylate (GMA@NH2-UIO), were utilized as the novel functional anti-corrosive fillers. The functionality, high surface area, phase composition, excellent thermal properties as well as chemical stability of the Zr-MOFs were proved by FT-IR, BET, XRD, TGA, and water stability tests, respectively. The smart pH-sensitive controlled-release activity of the corrosion inhibitors (i.e., Zr ions and organic compounds) from the prepared Zr-MOFs was proved by the water stability test of the Zr-MOFs particles in the acidic (pH = 2), neutral (pH = 7.5), and alkaline (pH = 12) solutions containing 3.5 wt% sodium chloride. The active inhibition properties of the Zr-MOFs were obtained in saline solution by two methods of (i) the solution phase and (ii) scratched epoxy coated samples containing Zr-MOFs by Tafel polarization method and EIS analysis. According to the EIS data, the excellent barrier (passive) properties of the composite film filled with GMA@NH2-UIO particles (G-UIN/EP) were proved by the highest impedance level at the lowest f (frequency) (log (vertical bar Z vertical bar(10 mHz) = 9.86 Omega.cm(2)), the lowest value of the breakpoint frequency (log (f(b)) = -1.42 Hz) and the highest coating undamaged index (85.93%) after 120 h of immersion. The salt spray (accelerated corrosion test) test (SST), pull-off (testing the strength of adhesion), and cathodic disbonding test (CDT) experiments showed excellent interfacial-adhesion properties of the G-UIN/EP sample in two dry (unexposed) and wet conditions. The hardness test showed that through the incorporation of the UIO, UIN, and G-UIN particles into the epoxy coating, the hardness, and scratch-resistance of the coating were notably improved.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 10147-36-1. The above is the message from the blog manager. COA of Formula: https://www.ambeed.com/products/10147-36-1.html.

Hydrazonoyl halides have been known for their ability to react with different reagents to afford wide range of bioactive heterocyclic systems as thiazoles and imidazopyrazoles. This research work focused on the synthesis of two new fluorinated hydrazonoyl chlorides and used them in synthesis of novel series of thiazole derivatives and two imidazopyrazole systems. The mechanistic pathways and the structures of all synthesized derivatives were discussed and assured based on the available spectral data. The results of antimicrobial activity of the tested thiazoles and imidazopyrazoles showed that some derivatives have moderate to no activity against tested fungi and bacteria strains. Only one derivative namely 2-(2-(3-fluoro-4-methylphenyl)hydrazono)-7-(2-oxoindolin-3-ylidene)-2,7-dihydro-3H-imidazo[1,2-b]pyrazole-3,6(5H)-dione is the most active against Candida albicans (CA) with IZD = 20 mm, which was equipotent to ketoconazole. Furthermore, docking simulation was carried out to predict the binding pattern of the new compounds in the ATP binding site of the DNA gyrase B enzyme. The results of the docking simulation revealed that compounds 9a-e, 12, and 13a,b fit well in the ATP binding site of DNA gyrase B with docking score values ranging from -5.883 to -6.833 kcal/mol.
