This study set out to examine the corrosion inhibiting properties of two novel benzimidazole derivatives, namely 1,4-bis(2-(4-chlorophenyl)-1H-benzo[d]imdazol-1-yl)butane (IM-Cl) and 1,4-bis(2-phenyl-1H-benzo[d]imidazol-1-yl)butane (IM-H) towards mild steel in HCl solution. In this study, gravimetric, electrochemical and scanning electron microscopy (SEM) techniques were applied to gain a detailed understanding of inhibition effects of IM-CI and IM-H on steel corrosion. Also, the present study aimed to explore the relationship between functional properties of the inhibitor molecules and their adsorption capacities on the MS surface with the aid of computational methods. Experimental results obtained by weight loss, potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) measurements revealed that tested compounds had a good anticorrosion capacity. Chloride substituted benzimidazole demonstrated the best inhibition performance reaching 93% at 5 x 10(-3) mol/L. The polarization technique (PDP) showed that the target molecules belonged to mixed-type inhibitors, preventing simultaneously anodic and cathodic reactions. Besides, the interactions mode between benzimidazole derivatives and mild steel surface followed the Langmuir adsorption model, and physical and chemical interactions assisted the adsorption mechanism of both compounds. EIS measurements illustrated that the imidazole derivatives made a positive impact on the mild steel corrosion process by increasing the polarization resistance with an increase in the concentration of the inhibitors. SEM analyses were performed to examine the surface morphology of uninhibited and inhibited steel and demonstrated good protection of the mild steel surface in the presence of tested compounds. Further, the temperature and immersion time effects on inhibition performances of benzimidazole were examined to evaluate the stability of these compounds under different operating conditions. Additionally, information extracted from theoretical approaches using Density Functional Theory (DFT) and molecular dynamics (MD) studies is in agreement with those obtained by experimental methods, which corroborate the strong anticorrosion activity of benzimidazole compounds under investigation.

Orexin-A (OXA) protects neurons against cerebral ischemia-reperfusion injury (CIRI). Endoplasmic reticulum stress (ERS) induces apoptosis after CIRI by activating caspase-12 and the CHOP pathway. The present study aimed to determine whether OXA mitigates CIRI by inhibiting ERS-induced neuronal apoptosis. A model of CIRI was established, in which rats were subjected to middle cerebral artery occlusion with ischemic intervention for 2 h, followed by reperfusion for 24 h. Neurological deficit examination and 2,3,5-triphenyltetrazolium chloride staining were performed to assess the level of CIRI and neuroprotection by OXA. Expression levels of ERS-related proteins and cleaved caspase-3 were measured via western blotting, while the rate of neuronal apoptosis in the cortex was determined using a TUNEL assay. OXA treatment decreased the infarct volume of rats after CIRI and attenuated neuron apoptosis. Furthermore, administration of OXA decreased the expression levels of GRP78, phosphorylated (p)-PERK, p-eukaryotic initiation factor-2 alpha, p-inositol requiring enzyme 1 alpha, p-JNK, cleaved caspase-12, CHOP and cleaved caspase-3, all of which were induced by CIRI. Collectively, these findings suggested that OXA attenuated CIRI by inhibiting ERS-mediated apoptosis, thus clarifying the mechanism underlying its neuroprotective effect and providing a novel therapeutic direction for the treatment of CIRI.

Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, Safety of O-Phenyl carbonochloridothioate, 1005-56-7, Name is O-Phenyl carbonochloridothioate, SMILES is S=C(Cl)OC1=CC=CC=C1, belongs to chlorides-buliding-blocks compound. In a document, author is Ozturk, Ibrahim I., introduce the new discover.

Ten novel bismuth(III) halide complexes of [Bi(L)X-3](n), [Bi(L)(2×3)](2), and [Bi(L)(3X3)] structural types were synthesized, in which L: 5-ethoxy-2-mercaptobenzimidazole, 5-methoxy-2-mercaptobenzimidazole and N-methylbenzothiazole. Bismuth(III) halide complexes 1-10 were characterized by melting point, elemental analysis, molar conductivity, FT-IR, FT-Raman, UV-Visible, H-1 and C-13 NMR spectroscopic techniques, as well as by the Thermogravimetric-Differential Thermal Analysis (TG-DTA). The crystal structures of complexes 1-10 were determined by using single crystal X-ray diffraction study. The results show that the bismuth(III) complexes exist as monomer (4), doubly-bridged dimer (1-3 and 5-9), and edge-sharing polymer (10), in which the central bismuth atom is a six-coordinated and adopts distorted octahedral geometries. We report here, for the first time, cis-sulfur, cis-halide arrangement of the doubly-bridged dimer bismuth(III) complexes. The intermolecular interactions in bismuth(III) complexes play a very important role in the supramolecular architecture. A detailed analysis of the intermolecular interactions has been performed as based on the Hirshfeld surfaces and their associated two-dimensional fingerprint plots. Bismuth(III) halide complexes 1-10 and their free ligands have been screened for antimicrobial activity against two Gram negative bacteria (Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853) and two Gram positive bacteria (Staphylococcus aureus ATCC 25923 and Enterococcus faecalis ATCC 29212). The influence of complexes 1-10 and the free ligands on the catalytic peroxidation of the linoleic acid by the enzyme lipoxygenase (LOX) has been determined experimentally and theoretically.

Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Quality Control of Chloromethyl pivalate, 18997-19-8, Name is Chloromethyl pivalate, molecular formula is C6H11ClO2, belongs to chlorides-buliding-blocks compound. In a document, author is Silva Ribeiro, Fabio de Oliveira, introduce the new discover.

In the present work, we investigated the minimal inhibitory concentration (MIC) against fungal strains (Fonsecaea pedrosoi, Microsporum canis, Candida albicans, Cryptococcus neoformans), and cytotoxicity to normal cell lines for modified red angico gum (AG) with eterifying agent N-chloride (3-chloro-2-hydroxypropyl) trimethylammonium (CHPTAC). Quaternized ammonium groups were linked to AG backbone using N-(3-chloro-2-hydroxypropyl) trimethylammonium chloride. The chemical features of the quaternized gum derivatives (QAG) were analyzed by: FTIR, elemental analysis, Zeta potential and gel permeation chromatography. The angico quaternizated gum presented a degree of substitution (DS) of 0.22 and Zeta potential of +36.43. For the antifungal test, it was observed that unmodified gum did not inhibit fungal growth. While, QAG inhibited the growth of most fungi used in this study. By AFM technique QAG interacted with the fungal surface, altering wall roughness significantly. The probable affinity of fragments of the QAG structure for the fungal enzyme 5I33 (Adenylosuccinate synthetase) has been shown by molecular docking. Low cytotoxicity was observed for polymers (unmodified gum and QAG). The results demonstrate that the quaternized polymer of AG presented in this study is a quite promising biomaterial for biotechnological applications. Published by Elsevier B.V.

A detection system based on a microchannel plate with a delay line readout structure has been developed to perform scanning transmission ion microscopy (STIM) in the helium ion microscope (HIM). This system is an improvement over other existing approaches since it combines the information of the scanning beam position on the sample with the position (scattering angle) and time of the transmission events. Various imaging modes, such as bright field and dark field or the direct image of the transmitted signal, can be created by post-processing the collected STIM data. Furthermore, the detector has high spatial and temporal resolution, is sensitive to both ions and neutral particles over a wide energy range, and shows robustness against ion beam-induced damage. A special in-vacuum movable support gives the possibility of moving the detector vertically, placing the detector closer to the sample for the detection of high-angle scattering events, or moving it down to increase the angular resolution and distance for time-of-flight measurements. With this new system, we show composition-dependent contrast for amorphous materials and the contrast difference between small-angle and high-angle scattering signals. We also detect channeling-related contrast on polycrystalline silicon, thallium chloride nanocrystals, and single-crystalline silicon by comparing the signal transmitted at different directions for the same data set.

The photocatalytic water-splitting hydrogen evolution technology has the potential to relieve energy crisis and enhance the hydrogen generation efficiency of the catalyst. Herein, a kind of 3DOM-CN composite, which is composed of a three-dimensional ordered macroporous material based on g-C3N4, was synthesized through a colloidal template crystal method. After it was doped with Cl- and modified by carbon quantum dots (CQDs), the as-prepared xCQDs/Cl/3DOM-CN composite showed an evident hydrogen generation ability enhancement irradiated by visible light. The structures, composition, and optical and electrochemical properties of the prepared photocatalysts were comprehensively obtained by transmission electron microscopy (TEM), scanning electron microscopy, high-resolution-TEM, X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, UV-vis, electrochemical impedance spectroscopy, photocurrent, Mott-Schottky, and photoluminescence. The highest hydrogen evolution efficiency under visible-light irradiation was achieved by the 1%CQDs/Cl/3DOM-CN composite with a hydrogen generation rate of 8.12 mmol g(-1) h(-1), which was nearly five times that of the 3DOM-CN. The photocatalyst exhibited an outstanding stability and reusability after four cycles. Eventually, the mechanism in the process of catalytic hydrogen production was briefly discussed. The synergy of the multiple functions of the CQDs/Cl/3DOM-CN composite offered a technique for enhancing the activity of the photocatalysts in the photocatalytic water-splitting process.

The molecular calcium hydride, [(BDI)CaF](2) (BDI = HC{(Me)CN-2,6-i-Pr2C6H3}(2)), effects the slow hydrodehalogenation of C6H5X (X = I, Br) to provide benzene and the respective dimeric calcium halides, [(BDI)CaX](2). Although a similar reaction with fluorobenzene was non-discriminating, the analogous hydrogenation of chlorobenzene was observed, albeit this process yields the calcium hydride-chloride as the alkaline earth-containing product. Assessment of the bromide- and chloride-based processes by density functional theory (DFT) calculations, imply that the reactions take place with the retention of the dimeric calcium structures throughout. Both systems invoke an S N Ar-type displacement of the halide, via barriers (in the range 32-34 kcal mol(-1) for C6H5Br and 31.1-32.9 kcal mol(-1) for C6H5Cl), which vary only marginally during the transformation of the initial hydride and halide-hydride intermediates. The isolation of the calcium hydride-chloride is ascribed, therefore, to its more rapid crystallisation and depletion from solution. Also reported is the reactivity of [(BDI)CaH](2) with alpha,alpha,alpha-trifluorotoluene and anisole, which yield the corresponding dicalcium hydride-fluoride and phenoxide derivatives, respectively, rather than the products of directed ortho metalation.

Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 1119-46-6, Name is 5-Chloropentanoic acid, molecular formula is C5H9ClO2.

Techniques using membranes for the treatment of wastewaters usually promote higher quality of treated water when compared to other processes. Among them, pervaporation has advantages in terms of selectivity in addition to low working pressure, which can prevent clogging problems. Polysulfone and polyurethane have complementary characteristics and are interesting in the context of membranes for industrial applications. In this sense, the aim of this work was to prepare and characterize polysulfone/polyurethane-based membranes and tested them with a simulated wastewater containing the reactive black dye and sodium chloride by pervaporation. In their manufacture, thermal treatment (at 60 degrees C) and photo-radiation treatment (using ultraviolet light) were also applied. The characterizations were performed using different analytical tools. In general, it was possible to verify that all membranes have a dense layer. The thermal analysis allowed to define that the indicated working temperature is below 50 degrees C. With respect to the simulated wastewater treatment, all membranes reached 100% selectivity. Concerning the saline solution, the mean selectivity was around 98.5%. Moreover, the permeate flow values were within the range presented by commercial membranes ranging from 1.6 to 2.4 kg m(-2) h(-1). Although for the photoirradiated membranes the photo-graft reaction has occurred, among all membranes, the blend without any treatment stood out from the others, presenting the highest permeate flow of the simulated wastewater. Finally, the results reveal that these membranes are capable of recovering wastewater from textile processes, in addition to having the potential to remove salts from water through the pervaporation process.

Deep eutectic solvents (DES) formed by quaternary ammonium salts and hydrogen bond donors are a promising green alternative to organic solvents. Their high viscosity at ambient temperatures can limit biocatalytic applications and therefore requires fine-tuning by adjusting water content and temperature. Here, we performed a meta-analysis of the impact of water content and temperature on the viscosities of four deep eutectic solvents (glyceline, reline, N,N-diethylethanol ammonium chloride-glycerol, N,N-diethylethanol ammonium chloride-ethylene glycol), their components (choline chloride, urea, glycerol, ethylene glycol), methanol, and pure water. We analyzed the viscosity data by an automated workflow, using Arrhenius and Vogel-Fulcher-Tammann-Hesse models. The consistency and completeness of experimental data and metadata was used as an essential criterion of data quality. We found that viscosities were reported for different temperature ranges, half the time without specifying a method of desiccation, and in almost half of the reports without specifying experimental errors. We found that the viscosity of the pure components varied widely, but that all aqueous mixtures (except for reline) have similar excess activation energy of viscous flow E-eta(excess)= 3-5 kJ/mol, whereas reline had a negative excess activation energy (E-eta(excess)= – 19 kJ/mol). The data and workflows used are accessible at https://doi.org/10.15490/FAIRDOMHUB.1.STUDY.767.1.
