This paper discusses the corrosion behavior of stirrups in two concrete beams under sustained loading, exposed to a chloride environment for 9 years. The cracking maps of concrete beams were recorded after 28 days and after 9 years, respectively. The corrosion maps of the stirrups were drawn and the cross-sectional losses of stirrups were measured after destroying the beams. The experimental results show that the horizontal legs of stirrups mainly corroded at the mid span of the tensile zone and at the ends of the compressive zone of the reinforced concrete beams regardless of the exposure conditions, while the opposite horizontal legs were protected. The corrosion of vertical legs of stirrups, which was slight, was not impacted by the load-induced cracks. In the present study, it is difficult to find the correlation of corrosion degree between stirrups and the main reinforcing steels in the reinforced concrete beams. The corrosion behavior of the intersection between stirrups and main bars was controlled by the interfacial conditions between them. Cathodic protection occurred at the ends of the top-cast side and the mid-span of bottom-cast side of reinforced concrete beams when the compressive rebars and tensile rebars were placed at the top- and bottom- cast sides, respectively.

Landfill refuse is a mixture of inorganic minerals and organic matter that is capable of undergoing complexation and redox reactions due to its active functional groups. Organic matter often combines with minerals in landfill refuse and it remains unclear whether this combination involves electron transfer. Therefore, the effects of landfill refuse composition on reductive dechlorination and speciation transformation of heavy metals were investigated in this study. Results show that landfill refuse comprises protein- and humic-like substances, aliphatic structures, and a large number of hydroxyl, carboxyl, quinoid and other active functional group. The electron donating capacity (0.09-0.26 mu mol/g(C)) of landfill refuse was found to be higher than its electron accepting capacity (0.03-0.23 mu mol/g(C)), indicating that electron donating groups (hydroxyl) were the main redox-active moieties, facilitating the reductive dechlorination of pentachlorophenol (PCP) by microorganism. Fe2O3, FeO and SiO2 were the main inorganic minerals affecting PCP dechlorination. The speciation distribution of heavy metals in landfill refuse was determined by the BCR sequential extraction method. Results showed that Zn and Ni have high potential migration capacity, poor stability and the highest bioavailability, while Cr, Cu and Pb are relatively stable and have weak migration potential. The oxygen- and nitrogen-containing functional groups, aliphatic structures and aromatic carbon in landfill refuse can promote the transformation of Ni and Cr from an unstable to stable state. Protein-like substances exhibit a strong Cu binding ability, allowing Cu to combine with organic matter more easily than other assessed heavy metals. Both Fe2O3 and FeO affected the stability of Cu. FeO promoted the stabilization of Zn, whereas Fe2O3 and SiO2 promoted Cu instability. These results could provide some references for the treatment of organic chlorides and the stabilization of heavy metals in landfill refuse in China. (C) 2020 Elsevier B.V. All rights reserved.

Synthetic Route of 320-51-4, As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 320-51-4, Name is 4-Chloro-3-(trifluoromethyl)aniline, SMILES is C1=C(C=CC(=C1C(F)(F)F)Cl)N, belongs to chlorides-buliding-blocks compound. In a article, author is Niu, Lingzhi, introduce new discover of the category.

Cataracts have a high incidence and prevalence rate worldwide, and they are the leading cause of blindness. Lens epithelial cell (LEC) apoptosis is often analysed in cataract research since it is the pathological basis of cataracts, except for congenital cataract. Chloride channels are present in ocular tissues, such as in trabecular cells, LECs and other cells. They serve an important role in apoptosis and participate in endoplasmic reticulum (ER) stress and oxidative stress. However, their role in the apoptosis of LECs has not been discussed. The present study examined the effects of the chloride channel blocker 5-nitro-2-(3-phenylpropylamino) benzoic acid (NPPB) in human LECs (HLECs) to elucidate the role of NPPB in HLECs and investigate the role and mechanism of chloride channels in cataract formation. HLECs were exposed to NPPB. Cell survival rate was evaluated using Cell Counting Kit-8 assays. Oxidative stress was detected as reactive oxygen species (ROS) in cells by using a ROS assay kit. Apoptosis was examined by assessing mitochondrial membrane potential and using a JC-1 assay kit, and western blot analysis was performed to measure the expression levels of mitochondrial-dependent apoptosis pathway-associated proteins. ER stress was evaluated by determining the intracellular calcium ion fluorescence intensity, and western blot analysis was performed to measure ER stress-associated protein expression. The results revealed that NPPB treatment decreased the viability of HLECs and increased apoptosis. Additionally, NPPB increased intracellular ROS levels, as well as the number of JC-1 monomers and the protein expression levels of B-cell lymphoma-2 (Bcl-2)-associated X and cleaved caspase-3, and decreased Bcl-2 protein expression. NPPB increased intracellular calcium ions, the protein expression levels of activating transcription factor 6, JNK, C/EBP homologous protein and caspase-12, and the phosphorylation of protein kinase R-like endoplasmic reticulum kinase. N-acetylcysteine and 4-phenylbutyric acid inhibited NPPB-induced oxidative stress, ER stress and apoptosis. Therefore, NPPB treatment decreased cell viability and promoted apoptosis of HLECs via the promotion of oxidative and ER stress.

AlCl4 ions are considered the intercalated species, reversibly intercalated/deintercalated between graphite layers, when graphite is used as an active material for Al batteries; however, the reaction mechanism of intercalated species in Al batteries has not yet been fully understood. In order to understand the process, we quantitatively evaluated the charge/discharge reactions of graphite in an ionic liquid consisting of 1-ethyl-3-methylimidazolium chloride and AlCl3 by electrochemical quartz crystal microbalance and density functional theory calculations. The presence of AlCl4 and Al2Cl7 as the intercalated species in the graphite interlayer was confirmed at a ratio of 0.76:0.24. Additionally, the capacity was retained after the destruction of the graphite structure because of its pseudocapacitive behavior. (C) 2020 Elsevier B.V. All rights reserved.

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, 74-11-3, Name is 4-Chlorobenzoic acid, SMILES is O=C(O)C1=CC=C(Cl)C=C1, in an article , author is Al-Hussain, Sami A., once mentioned of 74-11-3, Application In Synthesis of 4-Chlorobenzoic acid.

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.

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.

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.

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.

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.
