Perovskite solar cells have emerged as a promising next-generation electrical power generating tool. However, imperfections in perovskite films are one of the crucial factors preventing the commercialization of perovskite solar cells. Passivation has proven to be an effective strategy to reduce the density of defect states in perovskite crystals and inhibit ion migration. Although significant work on chloride ion and N,N-dimethylformamide (DMF) has shown that the additives are able to passivate different types of trap defects, systematic studies on the effects of DMF and HCl on perovskite crystallization when used in conjunction with each other are elusive. Here, we systematically investigated the synergistic effect of DMF and hydrochloric acid (HCl) on methylammonium (MA(+))-based perovskite films with the two-step spin-coating method. As a Lewis base, DMF coordinates well with Pb2+ to facilitate a decrease in the number of defects, thereby improving the carrier separation and transport, while HCl improves the overall perovskite film morphology. Addition of 20 mu L HCl/20 mu L DMF to 10 mL of methylammonium iodide/isopropyl alcohol solution afforded ca. 500 nm thick perovskite films with no observable defects within the grains. The process allowed fabrication of devices with an active area of 0.16 cm(2), which produced power conversion efficiencies up to 18.37% with minimal hysteresis.

Reinforced concrete (RC) structures in cold regions are subjected to double attacks of chloride erosion and freeze-thaw cycles (FTCs), accelerating the deterioration of concrete performance. Here, a multi-phase mesoscopic numerical model is proposed to systematic study the diffusion mechanism of chloride under the FTCs. Unlike most of existing models, the interface transition zone (ITZ) with random thickness is taken into account in the proposed concrete meso-structure. Moreover, the relationship between FTCs damage and chloride diffusion coefficient of concrete is deduced from the classical Aas-Jakobsen S-N equation. The reliability of the proposed model is further verified by compared with the third-party experiments data. It is evident from the proposed model that FTCs can promote the chloride diffusion. More importantly, this promoting effect is obvious when the number of FTCs is close to the limit number of FTCs. Specially, the mechanism of ITZ promoting the chloride diffusion is revealed by simulating the chloride diffusion trajectories in concrete meso-structure. Interestingly, despite the existence of FTCs in cold regions, chloride is diffused more rapidly in the tropical regions. Our findings reveal previously ignored fundamental aspects of the chloride diffusion mechanism under FTCs, and provide insights for the durability prediction of RC structures. (C) 2020 Elsevier Ltd.

In an article, author is Arvidsson, Emma, once mentioned the application of 2687-12-9, Quality Control of Cinnamyl chloride, Name is Cinnamyl chloride, molecular formula is C9H9Cl, molecular weight is 152.6208, MDL number is MFCD00000986, category is chlorides-buliding-blocks. Now introduce a scientific discovery about this category.

Structural synaptic reorganizations needed to permanently embed novel memories in the brain involve complex plasticity-enhancing and plasticity-inhibiting systems. Increased neural activity is linked to rapid downregulation of Nogo receptor 1 (NgR1), needed to allow local structural synaptic plasticity. This local regulation of plasticity is thought to be moderated by global systems, such as the ascending cholinergic and monoaminergic systems, adding significance to locally increased neural activity. Here we address the reverse possibility that the global systems may also be influenced by the status of local plasticity. Using NgR1-overexpressing mice, with impaired plasticity and long-term memory, we measured the ability to release dopamine (DA), implicated in regulating plasticity and memory. In vivo chronoamperometric recording with high temporal and spatial resolution revealed severe impairment of potassium chloride (KCI)-induced increase of extracellular DA in the dorsal striatum of mice overexpressing NgR1 in forebrain neurons. A similar, but lesser, impairment of DA release was seen following amphetamine delivery. In contrast, potassium chloride-evoked DA release in NgR1 knockout (KO) mice led to increased levels of extracellular DA. That NgR1 can impair DA signaling, thereby further dampening synaptic plasticity, suggests a new role for NgR1 signaling, acting in synergy with DA signaling to control synaptic plasticity. Significance Statement: The inverse correlation between local NgR1 levels and magnitude of KCl-inducible amounts of DA release in the striatum reinforces the rule of NgR1 as a regulator of structural synaptic plasticity and suggests synergy between local and global plasticity regulating systems.

Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Du, Qiwei, once mentioned the application of 6276-54-6, Name is 3-Chloropropan-1-amine hydrochloride, molecular formula is C3H9Cl2N, molecular weight is 130.02, MDL number is MFCD00012913, category is chlorides-buliding-blocks. Now introduce a scientific discovery about this category, Category: chlorides-buliding-blocks.

In this study, the effect of calcium ions (Ca2+) on the heat stability and rheology of high-calorie (>1.0 kcal/mL) whey protein emulsion (HCWPE) was investigated. The mass fractions of carbohydrate, lipid and protein in the emulsions were 20, 6, and 6 wt%, respectively. It was found that there was little difference in stability and rheology between emulsions (unheated) of different concentrations of Ca2+. However, after high-temperature sterilization (121 degrees C for 15 min), Ca2+ had a significant effect on the stability of HCWPE. The particle size and flocculation degree increased rapidly when the Ca2+ concentration was above 1.5 mM, and absolute.-potential decreased. The change of 3-week particle size and backscattering showed that the emulsion had better storage stability when the Ca2+ concentration was below 1.5 mM. Another interesting result was that after the high temperature sterilization, the rheological behavior of HCWPE changed from shear-thickening to shearthinning with increase in Ca2+ concentration. It could be explained that free Ca2+ continued to bind with protein during the shearing process. The present study would provide a theoretical reference for calcium fortified functional drinks.

The heterodimetallic [CuFe] compounds [Cu-4(II) (terpy)(4)Cl-5]-[Fe-III(C2O4)(3)]center dot 10H(2)O (1;terpy = 2,2′:6′,2 ”-terpyridine), [Cu-2(II)-(H2O)(2) (terpy)(2) (C2O4)][(CuFeIII)-Fe-II (CH3OH)(terpy)(C2O4)(3)](2) (2), and {[(Cu2FeIII)-Fe-II (H2O)(terpy)(2) (C2O4)(7/)(2)]center dot 6H(2)O}(n) (3) were obtained using building block approach, from reaction of aqueous solution of [Fe(C2O4)(3)](3-) and a methanol solution containing Cu2+ ions and terpy by the layering technique. Interestingly, by changing only the anion of the starting salt of copper(II), Cu(NO3)(2)center dot 3H(2)O instead of CuCl2 center dot 2H(2)O, an unexpected change in the type of bridge, oxalate (2 and 3) versus chloride (1), was achieved, thus affecting the overall structural architecture. Two polymorphs of 3D coordination polymer [(CuFe2II)-Fe-II(H2O)(terpy)(C2O4)(3)](n) (4), crystallizing in the triclinic (a) and monoclinic (b) space groups, were formed hydrothermally, depending on whether CuCl2 center dot 2H(2)O or Cu(NO3)(2)center dot 3H(2)O was added 3 to the water, besides K-3[Fe(C2O4)(3)]center dot 3H(2)O and terpy, respectively. Under hydrothermal conditions iron(III) from initial building block is reduced to the divalent state, creating 2D honeycomb [Fe-2(II)(C2O4)(3)](n)(2n-)- layers, which are bridged by [Cu(H2O)(terpy)](2+) cations. Compounds were investigated by single-crystal X-ray diffraction, IR, and impedance spectroscopies, magnetization measurements, and density functional theory (DFT) calculations. In compounds 1 and 2, OD magnetism is observed, with 1 having a ground-state spin of 1 due to different interactions through chloride bridges of Cu2+ ions in tetramer [Cu-4(II)(terpy)(4)Cl-5](3+) and 2 showing strong antiferromagnetic coupling of Cu2+ ions mediated by oxalate ligand in [Cu-2(II)(H2O)(2)(terpy)(2)(C2O4)](2+) and weak ones between Cu2+ and Fe3+ ions through oxalate bridge in [(CuFeIII)-Fe-II(CH3OH)(terpy)(C2O4)(3)](-). Polymer 4 exhibits antiferromagnetic phase transition at 25 K: The [Fe-2(II)(C2O4)(3)](n)(2n-) layers are antiferromagnetically ordered, and a small amount of interlayer interaction is transferred through [Cu(H2O)(terpy)](2+) cations via O-ox-Cu-O-ox bridges. Additionally, compounds 1 and 2 are electrical insulators, while 4a and 4b show proton conductivity.

Portland Cement Concrete (PCC) is the most used construction material worldwide and its use is expected to increase in the future. PCC intensively uses two main natural resources, namely aggregates and fresh water. The concrete industry consumes about 2 billion tons of potable water annually. Due to climate change, rapid population growth, and industrial activity, there is a scarcity of fresh water; by 2025 more than half of the world’s population will be living in water-stressed areas. In contrast, there is abundant seawater in the world, which represents about 97.5% of the total Earth’s water. However, the incorporation of seawater in PCC is a complex problem because the sulfate ions can affect the microstructure durability and the chloride ions can accelerate reinforcing steel corrosion, which can compromise the structural integrity. Glass Fiber Reinforced Polymer (GFRP) bars may be used as an alternative reinforcing material to avoid corrosion. This paper assesses the bond strength of two types of GFRP bars with either a sand-coating or spiral grooves using a standard pullout test. Control samples were prepared using concrete made with potable water and compared with companion specimens made with seawater. Parallel experimental programs were carried out in Chile and Canada, with a total of 70 test specimens. The results suggest that there is no statistically significant difference in the short-term (28 day) bond strength of GFRP bars in seawater concrete compared to normal concrete.

At room temperature, 2-aminomethylpyridine, Ln (NO3)(3)center dot 6H(2)O and (E)-2-((3-methoxy-2-oxidobenzylidene)amino)ethanesulfonate (L-1) in methanol and acetonitrile to obtain four complexes: [Ln(2)(L)(2)(NO3)(4)] (Ln = Sm (1), Eu (2), Gd (3), Tm (4), and L = (E)-2-methoxy-6-(((pyridin-2-ylmethyl)imino)methyl)phenol). The original organic ligand L-1 and 2-aminomethylpyridine reacted in situ under the catalyzed condition of Ln(III) ion to form a new Schiff base ligand L. In the above process, firstly, the C = N double bond in the original Schiff base ligand L-1 is broken and further combines with 2-aminomethylpyridine to form a new Schiff base ligand L. As far as we know, this is rare in the formation of lanthanide complexes. When Complex 2 was subjected to luminescence test, it was found to have an extremely high selectivity to acetonitrile (CH3CN) and methylene chloride (CH2Cl2). Therefore, after screening a variety of different organic solvents, here we explore a method that can quickly and efficiently respond to CH3CN/CH2Cl2. In addition, we can visually distinguish the response of Complex 2 to multiple volatile organic compounds (VOCs). The magnetocaloric effect (MCE) test of Complex 3 showed 18.7 J center dot kg(-1)center dot K-1 at 2 K for Delta H = 5 T.

Abdominal aortic aneurysm (AAA) is a great threat to the health of elder (>50 years old) individuals. High salt intake is considered to raise the risk of AAA but the underlying mechanism remains to be elucidated. As endothelial dysfunction in the abdominal aorta is strongly associated with AAA, the present study hypothesized that high salt led to AAA by inducing apoptosis of endothelial cells. The present study verified that hypertonic medium with excess sodium chloride induced apoptosis of human umbilical vein endothelial cells (HUVECs), a commonly used cell model to study aortic endothelial cells. Further mechanism studies suggested that hypertonic conditions elevated the expression of nuclear factor of activated T cells 5 (NFAT5) and a high level of NFAT5 was capable of inducing apoptosis of HUVECs. In the investigation of downstream signals of NFAT5, it was identified that either hypertonic conditions or NFAT5 overexpression promoted the activity of NF-kappa B signaling pathway and subsequently suppressed the expression of anti-apoptotic protein Bcl-2. Thus, the present study demonstrated a novel mechanism by which high salt induced apoptosis of endothelial cells by enhancing the NFAT5-NF-kappa B signaling pathway. These findings will extend our knowledge about the pathogenesis of AAA and provide potential drug targets for the treatment of AAA.

In this work, the recycled acrylonitrile-butadiene-styrene (rABS)/anhydrous zinc chloride (ZnCl2) composites were prepared and the reinforcing effects of the rABS/ZnCl2 composites were investigated using various characterization techniques. During heat pressing at 190 degrees C, a strong coordination interaction occurred between Zn2+ of ZnCl2 particles and -CN groups of rABS matrix, which resulting in an enhancement of mechanical and thermal properties in comparison with the neat rABS. Fourier transform infrared spectroscopy, dissolution experiments, ultraviolet-visible spectroscopy, and X-ray photoelectron spectroscopy were applied to prove the coordination reaction. Scanning electron microscopy showed ZnCl2 particles were homogeneously dispersed in the rABS matrix. Tensile test analysis showed that the flexural strength and tensile strength of rABS/ZnCl2 composites increased by around 12.07% and 18.17%, respectively, when adding 7 phr of ZnCl2 into the rABS resin. Furthermore, heat deflection temperature analysis, thermogravimetric analysis as well as dynamic mechanical analysis proved that the coordination reaction dramatically improved the heat resistance of rABS matrix. Besides, the recycling ability of the composites had also been proved.

The atmospheric SCC/pitting susceptibility of deposited MgCl2, synthetic sea-salt and site-specific sea-salt (containing ammonium and nitrate ions) on weld, HAZ and base 316L canister material was investigated. Higher SCC/pitting densities were observed for the HAZ region exposed to MgCl2, due to higher tensile residual stresses and plastic strains. Pitting in the weld region exposed to MgCl2 show preferential corrosion of delta-ferrite. Salt composition appears to have had a significant impact on SCC, pitting density and surface corrosion behaviour. Maximum surface crack propagation rates in the HAZ of 4 x 10(-11) ms(-1) were obtained for both synthetic sea-salt and MgCl2. (C) 2020 Published by Elsevier B.V.
