The interactions of cationic surfactant cetyltrimethyl ammonium chloride (CTAC) and polyacrylamide (PAM) in drag reduction solutions are studied by experiments and simulations. Cryogenic Transmission Electron Microscopy shows that CTAC and PAM form aggregates with interconnected network structures, and the bridge effect from polymers can improve the network structures’ density. The associated potential of mean force (PMF) value indicates that surfactant/polymer attractions contribute to the formation of aggregates. Meanwhile, the mechanism of the enhanced drag reduction performance of surfactant/polymer solution is discussed by the extension energy of the aggregate structures. It is found that the interactions of surfactants and polymers help to improve the anti-shear performance of the surfactant micelles. Furthermore, polymers can balance micelles energy distribution, postpone the appearance of energy extreme point, and delay the rupture of micelles. This work fundamentally demonstrates that interactions and strengthened structures of micelle aggregates can intensify drag reduction in surfactant/polymer solutions. (C) 2020 Elsevier Ltd.

Ionic liquid-based microwave-assisted extraction (MAE-IL) has been applied for the separation of essential oils (EOs) from Citrus sinensis var. Valencia peels. Two imidazolium ionic liquids, 1-ethyl-3-methyl imidazolium acetate ([C(2)mim]OAc) and 1-butyl-3-methyl imidazolium chloride ([C-4 mim]Cl), were investigated for extraction efficiency, thermal behavior of the process, and chemical composition of the EOs obtained. During extractions, two different concentrations of ionic liquids (ILs) were studied (5% or 10 %), and the proposed MAE-IL was evaluated in comparison with usual microwave-assisted extraction (MAE) using water as solvent. Results indicated that both concentrations of ILs influenced EO extraction, thermal behavior, and chemical composition. However, [C(2)mim]OAc was more efficient, increasing extraction velocity by 10 times, enhancing extraction efficiency of EOs (39 %), and increasing the presence of oxyterpene compounds in the EOs. However, the great ability of ILs to interact with microwaves had an impact on the thermal history of the sample, reaching almost 110 degrees C, promoting the presence of compounds related to thermal effect.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 106246-33-7 is helpful to your research. Recommanded Product: 106246-33-7.

Green nanotechnology has recently had a significant influence on advances in biological applications. The surface manipulation of iron oxide NPs by zinc oxide is increasing attention for biomedical research. Therefore, this work focused on the phytochemicals of creeper Blepharis maderaspantensis (BM) water extract for synthesizing iron oxide NPs and iron oxide/zinc oxide nanocomposite. The UV spectrum analysis showed a wavelength redshift from 294 to 302 nm of iron oxide/ZnO nanocomposite, and the polydispersity index revealed that the perfect preparations of iron oxide NPs were prepared by boiling 0.25 g of the plant in deionized water then the filtrate added to ferric chloride (1:1 v/v). The HRTEM results also illustrated that amorphous iron oxide NPs are spherical and irregular in shape. However, the iron oxide/ZnO nanocomposite showed a rod shape of ZnO with an average length and width of similar to 19.25 +/- 3.2 x 3.3 +/- 0.6 nm surrounding amorphous iron oxide NPs. Furthermore, a high antimicrobial activity with MRSA and E. coli was demonstrated by iron oxide NPs. However, because of instability and negative surface charge of the iron oxide nanocomposite, there was no antimicrobial activity. Future cytotoxic studies of the iron oxide NPs synthesized with polyphenols of BM extract are desirable, and their applications in medical purposes will be recommended.

There is a high demand for facile on-site mercury ion quantification methods in water due to mercury’s serious toxicity. Graphene quantum dot (GQD), fluorescent under ultra-violet (UV) light, can be easily synthesized and used as a mercury ion detection probe because the brightness of GQD’s fluorescence decreases with the increase of the number of mercury ions. We developed a facile mercury (II) ion quantification method using GQD coated filter paper disks in a 3D-printed well array. Changes of GQD’s fluorescent brightness dependent on mercury ion concentration were measured via optical microscopy image processing. We also observed the dependency of mercury ion detection sensitivity on the amount of GQD and type of GQDs. Our approach may be easily adapted for hand-held mobile mercury ion quantification devices in the future due to its simplicity and small sample size.

Chemical polymerization of o-phenylenediamine (OPD) in the presence of poly(ethylene oxide), double-wall carbon nanotubes (DWNTs) and ferric chloride is carried out in order to obtain composites based on the poly(o-phenylenediamine)-poly(ethylene oxide) (POPD-PEO) fibres covered and interconnected with DWNTs. Vibrational and photoluminescence properties of these composite materials as well as their morphologies are shown by infrared (IR) spectroscopy, Raman scattering, photoluminescence (PL) and scanning electron microscopy (SEM). An adsorption of DWNTs onto the POPD rods surface in the absence and in the presence of. PEO is highlighted by SEM. The vibrational changes reported by Raman scattering and IR spectroscopy prove a covalent functionalization of DWNTs with the macromolecular compound POPD which is doped with FeCl4- T ions. New hydrogen bonds are generated between POPD covalently functionalized DWNTs and hydroxyl groups of PEO according to IR spectroscopic studies. The two macromolecular compounds, POPD and POPD-PEO, show a complex emission band with maxima at 572 and 566 nm, having a shoulder at 667 nm. A significant change in the profile of the PL bands of POPD and POPD-PEO is induced in the DWNTs presence. We show that DWNTs induce (i) a diminution in the POPD PL band intensity peaked between 525-600 nm simultaneous with the increase in the intensity of the PL band situated in the 600-800 nm spectral range and (ii) an enhancement process of the emission band localized in the 475-800 nm spectral range in the case of POPD-PEO.

A series of Fe(II) complexes (1-4) and Fe(III) complexes (5-8) from Fe(II)/(III) chloride and N-(8-quinolyl)-X-salicylaldimine Schiff base ligands (Hqsal-X-2/X: X = Br, Cl) were successfully synthesized and characterized by spectroscopic (FT-IR, H-1-NMR), mass spectrometry, thermogravimetric analysis (TGA), and single crystal X-ray crystallographic techniques. The interaction of complexes 1-8 with calf thymus DNA (CT-DNA) was determined by UV-Vis and fluorescence spectroscopy. The complexes exhibited good DNA-binding activity via intercalation. The molecular docking between a selected complex and DNA was also investigated. The in vitro anticancer activity of the Schiff base ligands and their complexes were screened against the A549 human lung adenocarcinoma cell line. The complexes showed anticancer activity toward A549 cancer cells while the free ligands and iron chloride salts showed no inhibitory effects at 100 mu M. In this series, complex [Fe(qsal-Cl-2)(2)]Cl 6 showed the highest anticancer activity aginst A549 cells (IC50 = 10 mu M). This is better than two well-known anticancer agents (Etoposide and Cisplatin). Furthermore, the possible mechanism for complexes 1-8 penetrating A549 cells through intracellular ROS generation was investigated. The complexes containing dihalogen substituents 1, 2, 5, and 6 can increase ROS in A549 cells, leading to DNA or macromolecular damage and cell-death induction. [GRAPHICS] .

Probiotic potential of Enterococcus spp. is widely investigated around the globe. The biochemically and molecular characterized E. faecium strains isolated from Dahi (continental yogurt) were evaluated to tolerate simulated gastric environment, bile, sodium chloride, temperature, and pH. The safety was assessed by disc diffusion, broth microdilution, antibiotic resistance genes screening, and hemolytic ability. Enterococci survived simulated gastrointestinal conditions and depicted growth at temperature (15 to >= 42 degrees C), pH (<= 2.5 to >= 9.5), 0.3% bile salt and 3% NaCl. All strains were sensitive to ampicillin, vancomycin, kanamycin, gentamicin, streptomycin, tetracycline and ciprofloxacin and harbored vanR, vanX, qnrB2, qnrS, tetK, and tetW resistance genes. E. faecium strains inhibited the E. coli (85%) and S. Typhi (50%) whereas the 10% cell-free culture supernatant (CFCS) of E. faecium halted the growth of E. coli while 15% CFCS completely suppressed S. Typhi. The cell-free culture supernatant retained antibacterial nature after pH and proteinase K treatment, however, it lost activity after heat treatment (>= 95 degrees C). The genetic screening revealed that all isolates are capable to produce putrescine biogenic amine. Further assessment of strains for lack of infectivity, cytotoxicity in animals, adhesion to Caco-2 cells and characterization of enterocins is essential to conclude the probiotic potential of these strains.

Synthetic and Mechanistic Implications of Chlorine Photoelimination in Nickel/Photoredox C(sp(3))-H Cross-Coupling

In recent years, the development of light-driven reactions has contributed numerous advances in synthetic organic chemistry. A particularly active research area combines photoredox catalysis with nickel catalysis to accomplish otherwise inaccessible cross-coupling reactions. In these reactions, the photoredox catalyst absorbs light to generate an electronically excited charge-transfer state that can engage in electron or energy transfer with a substrate and the nickel catalyst. Our group questioned whether photo-induced activation of the nickel catalyst itself could also contribute new approaches to cross-coupling. Over the past 5 years, we have sought to advance this hypothesis for the development of a suite of mild and site-selective C(sp(3))-H cross-coupling reactions with chloride-containing coupling partners via photoelimination of a Ni-Cl bond. On the basis of a report from the Nocera laboratory, we reasoned that photolysis of a Ni(III) aryl chloride species, generated by single-electron oxidation of a typical Ni(II) intermediate in cross-coupling, might allow for the catalytic generation of chlorine atoms. Combining this with the ability of Ni(II) to accept alkyl radicals, we hypothesized that photocatalytically generated chlorine atoms could mediate hydrogen atom transfer (HAT) with C(sp(3))-H bonds to generate a substrate-derived alkyl radical that is captured by the Ni center in cross-coupling. A photoredox catalyst was envisioned to promote the necessary single-electron oxidation and reduction of the Ni catalyst to facilitate an overall redox-neutral process. Overall, this strategy would offer a visible-light-driven mechanism for chlorine radical formation enabled by the sequential capture of two photons. As an initial demonstration, we developed a Ni/photoredox-catalyzed alpha-oxy C(sp(3))-H arylation of cyclic and acyclic ethers. This method was extended to a mild fonnylation of abundant and complex aryl chlorides through selective 2-functionalization of 1,3-dioxolane. Seeking to develop a suite of reactions that introduce carbon at all different oxidation states, we explored C(sp(3))-H cross-coupling with trimethyl orthoformate, a common laboratory solvent. We found that trimethyl orthofonnate serves as a source of methyl radical for a methylation reaction via beta-scission from a tertiary radical generated upon chlorine-mediated HAT. Since chlorine radical is capable of abstracting unactivated C(sp(3))-H bonds, our efforts have also been directed at cross-coupling with a range of feedstock chemicals, such as alkanes and toluenes, along with late-stage intermediates, using chloroformates as coupling partners. Overall, this platform enables access to valuable synthetic transformations with (hetero)aryl chlorides, which despite being the most ubiquitous and inexpensive aryl halide coupling partners, are rarely reactive in Ni/photoredox catalysis. Little is known about the photophysics and photochemistry of organometallic Ni complexes relevant to cross-coupling. We have conducted mechanistic investigations, including computational, spectroscopic, emission quenching, and stoichiometric oxidation studies, of Ni(II) aryl halide complexes common to Ni/photoredox reactions. These studies indicate that chlorine radical generation from excited Ni(III) is operative in the described C(sp(3))-H functionalization methods. More generally, the studies illustrate that the photochemistry of cross-coupling catalysts cannot be ignored in metallaphotoredox reactions. We anticipate that further mechanistic understanding should facilitate new catalyst design and lead to the development of new synthetic methods.
