Substituted planar chiral pyridyl[2.2]paracyclophanes were prepared by the palladium-catalyzed desulfinative cross-coupling of bromo[2.2]paracyclophanes and pyridine sulfinate salts. Pyridine-substituted [2.2]paracyclophanes are useful building blocks in the preparation of catalysts, functionalized materials, and luminescent molecules. Yet the synthesis of many pyridine-substituted [2.2]paracyclophanes is more challenging than expected due to the instability of traditional coupling partners. Pyridine sulfinates offer a solution to this shortcoming, permitting pyridyl[2.2]paracyclophanes to be prepared from readily available bromo[2.2]paracyclophanes. Our preliminary results indicate the potential of this chemistry. Amine, bromine and ester substituted planar chiral pyridines that are hard to synthesize by other methods were formed but formation of (bis)pyridines is still problematic.

Nanostructures of transition metal oxides, such as copper oxide (CuO), are attractive for their stability and cost-effectiveness. This work reveals that the precursor materials play a crucial role in tailoring the morphologies, properties of CuO nanostructures. Herein, three different copper precursors, such as copper acetate, copper chloride, and copper nitrate, have been used to prepare CuO nanostructures. We find that nanosphere morphology is formed when copper acetate and copper chloride are used, whereas nanoflower morphology is formed when copper nitrate is used as precursors. The synthesis of flower-like CuO nanostructures is attained by altering the precursor material alone, and the petals of these flowers have a thickness of around 50 nm. The photocatalytic properties of the CuO nanoparticles prepared with the different precursors are investigated for the degradation of methylene blue dye. At a certain dye concentration level, the small size of particles results in a higher surface-to-volume ratio, which causes an increase in the number of active surface sites. Owing to the lowest particle size, CuOsphere-A (copper acetate) performs the best photodegradation efficiency. Additionally, the nanoflower-like structure could provide better accessibility of the reactants on the surface of photocatalytic material, resulting in more favorable for the photodegradation.

Permeability is a major indicator of concrete durability, and depends primarily on the microstructure characteristics of concrete, including its porosity and pore size distribution. In this study, a variety of concrete samples were prepared to investigate their microstructure characteristics via nuclear magnetic resonance (NMR), mercury intrusion porosimetry (MIP), and X-ray computed tomography (X-CT). Furthermore, the chloride diffusion coefficient of concrete was measured to explore its correlation with the microstructure of the concrete samples. Results show that the proportion of pores with diameters < 1000 nm obtained by NMR exceeds that obtained by MIP, although the difference in the total porosity determined by both methods is minimal. X-CT measurements obtained a relatively small porosity; however, this likely reflects the distribution of large pores more accurately. A strong correlation is observed between the chloride diffusion coefficient and the porosity or contributive porosity of pores with sizes < 1000 nm. Moreover, microstructure parameters measured via NMR reveal a lower correlation coefficient R-2 versus the chloride diffusion coefficient relative to the parameters determined via MIP, as NMR can measure non-connected as well as connected pores. In addition, when analyzing pores with sizes > 50 mu m, X-CT obtains the maximal contributive porosity, followed by MIP and NMR.

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, 140-53-4, Name is (4-Chlorophenyl)acetonitrile, SMILES is ClC1=CC=C(CC#N)C=C1, in an article , author is Walaijai, Khanittha, once mentioned of 140-53-4, Computed Properties of C8H6ClN.

Cobalt complexes with 2-(diisopropylphosphinomethyl)-pyridine (PN) ligands have been synthesized with the aim of demonstrating electrocatalytic proton reduction to dihydrogen with a well-defined hydride complex of an Earth-abundant metal. Reactions of simple cobalt precursors with 2-(diisopropylphosphino-methyl)pyridine (PN) yield [Co-II(PN)(2)-(MeCN)][BF4](2) 1, [Co-III(PN)(2)(H)(MeCN)][PF6](2) 2, and [Co-III(PN)(2)-(H)(Cl)][PF6] 3. Complexes 1 and 3 have been characterized crystallo-graphically. Unusually for a bidentate PN ligand, all three exhibit geometries with mutually trans phosphorus and nitrogen ligands. Complex 1 exhibits a distorted square-pyramidal geometry with an axial MeCN ligand in a low-spin electronic state. In complexes 2 and 3, the PN ligands lie in a plane leaving the hydride trans to MeCN or chloride, respectively. The redox behavior of the three complexes has been studied by cyclic voltammetry at variable scan rates and by spectroelectrochemistry. A catalytic wave is observed in the presence of trifluoroacetic acid (TFA) at an applied potential close to the Co(II/I) couple of 1. Bulk electrolysis of 1, 2, or 3 at a potential of ca. -1.4 V vs E(Fc(+)/ Fc) in the presence of TFA yields H-2 with Faradaic yields close to 100%. A catalytic mechanism is proposed in which the pyridine moiety of a PN ligand acts as a pendant proton donor following opening of the chelate ring. Additional mechanisms may also operate, especially in the presence of high acid concentration where speciation changes.

Employing corn derived products to reduce the corrosivity of pavement deicing materials

The goal of this study is to reduce the corrosivity of traditional pavement deicers by employing environmentally safe and low-cost corn-derived polyols namely sorbitol, mannitol, and maltitol. The corrosion inhibition performance of polyols-mixed deicers is investigated for ASTM A572 Gr. 50 high strength low alloy steels. For this purpose, each polyol is added to the traditional deicer (23.0% wt. sodium chloride brine) in the following weight concentrations: 0.5%, 1.0%, 2.0% and 3.0%. The corrosion behavior of ASTM A572 Gr. 50 high strength low alloy steel is then quantified by conducting potentiodynamic polarization tests in the absence and presence of different polyols concentrations in the deicing solution. In addition to the polarization tests, accelerated corrosion tests are performed by continuously subjecting ASTM A572 Gr. 50 steel specimens to the periodic flow of polyols-based deicers in a hot and humid environment inside an environmental chamber to visually monitor the corrosion damage in steel specimens. The results obtained from both polarization tests and accelerated corrosion tests revealed that the addition of small concentrations of corn-derived polyols in the traditional salt brine deicer leads to substantial corrosion inhibition (up to 92%) in the ASTM A572 Gr. 50 steel used in this study. All three polyols are observed to obey the Langmuir’s adsorption isotherm and inhibit the corrosion in ASTM A572 Gr. 50 steels through physical adsorption on the steel surface. The potentiodynamic polarization test results further indicated the mixed-type corrosion inhibiting nature of polyols-based deicing solutions. (C) 2020 Elsevier Ltd. All rights reserved.

Mercury intrusion porosimetry parameters for use in concrete penetrability qualification using the Katz-Thompson relationship

This research studies relationships between pore parameters obtained from mercury intrusion porosimetry (MIP) and experimental results to determine the potential for those parameters to quantify concrete penetrability using the Katz-Thompson relationship. Water permeability, electrical resistivity, and chloride ion penetrability were analyzed as these test methods serve as a proxy for penetrability. Recent developments in mercury intrusion porosimetry accommodate testing larger concrete specimens instead of paste or mortar. Consequently, this work directly compares calculated and measured permeability of nineteen concrete mixtures. By oven-drying the MIP specimens, the calculated permeability was increased due to microcracking; however, when using the same specimen conditioning procedure for MIP and water permeability testing, the resulting calculated and measured water permeability values were comparable.

ZrO2 Monolayer as a Removable Etch Stop Layer for Thermal Al2O3 Atomic Layer Etching Using Hydrogen Fluoride and Trimethylaluminum

A ZrO2 monolayer was demonstrated as a removable etch stop layer (ESL) for thermal Al2O3 atomic layer etching (ALE) using HF and Al(CH3)(3) (trimethylaluminum (TMA)) as the reactants. The ZrO2 ESL was deposited on Al2O3 using tetrakis(ethylmethylamido)zirconium (TEMAZ) and H2O. In situ quartz crystal microbalance (QCM) measurements showed that a ZrO2 coverage of similar to 190 ng/cm(2) completely blocked thermal Al2O3 ALE at 285 degrees C. This ZrO2 coverage is equivalent to approximately one ZrO2 monolayer. The inhibition of the Al2O3 etch rate was proportional to the ZrO2 fractional coverage. The ZrO2 ESL was effective for hundreds of thermal Al2O3 ALE cycles. In terms of the surface chemistry, the ZrO2 ESL is known to be fluorinated to a ZrOxFy or ZrF4 layer by HF exposure. This fluorinated layer restricts etching by preventing the ligand-exchange reaction with TMA. The fluorinated layer could be easily removed using thermal ALE with HF and AlCl(CH3) (dimethylaluminum chloride (DMAC)) as the reactants. The ZrO2 ESL could be deposited and removed repeatedly without changing the Al2O3 etch rate. X-ray photoelectron spectroscopy (XPS) studies observed no trace of Zr on the Al2O3 surface after 7-8 cycles of HF and DMAC sequential exposures. Area selective deposition of the ZrO2 ESL would lead to area selective etching using HF and TMA as the reactants.

Cellular toxicology and mechanism of the response to silver-based nanoparticle exposure in Ewing’s sarcoma cells

Ewing’s sarcoma is the most aggressive connective tissue tumor, mainly affecting children and adolescents; the 5 year survival rate is only 50%. Current treatments have poor effectiveness, and more efficient treatments are being sought. Silver-based nanoparticles, such as silver chloride nanoparticles (AgCl-NPs) and silver/silver chloride (Ag/AgCl-NPs) nanoparticles, can be biologically produced and can release Ag+ ions into solution; however, their antitumor activity has been minimally investigated. The aim of this study was to evaluate the antitumor potential of AgCl-NPs and Ag/AgCl-NPs against Ewing’s sarcoma cells. A673 cells (Ewing’s sarcoma) were treated for 72 h with 0-12.5 mu g ml(-1) of Ag/AgCl-NPs or 0-40 mu g ml(-1) of AgCl-NPs. Human cells from the RPE-1 cell line (pigmented retinal epithelium) were used as a model of nontumor cells. The RPE-1 cells were less affected by the administration of AgCl-NPs or Ag/AgCl-NPs, with small reductions in the number of cells and viability and a small increase in apoptosis rates, while lysosomal damage, changes in reactive oxygen species (ROS) production, loss of mitochondrial membrane potential and alterations in microfilaments or cell areas were not observed. A673 tumor cells had significantly reduced number and viability levels when treated with AgCl-NPs, with reductions of 65.05% and 99.17%, respectively, whereas with Ag/AgCl-NP treatment, reductions of 65.53% and 92.51% were observed, respectively. When treated with silver-based nanoparticles, A673 cells also showed a significant increase in ROS production and loss of mitochondrial membrane potential, which culminated in an increase in the percentage of apoptosis among the population. Lysosomal damage was also observed when A673 cells were treated with the highest concentration of AgCl-NPs. In conclusion, the results showed that both AgCl-NPs and Ag/AgCl-NPs had some antitumor activity with minimal effects against healthy cells, which demonstrated the possibility of their use in cancer therapy.

A facile synthesis of pyrano[2,3-d:6,5-d ‘]dipyrimidines via microwave-assisted multicomponent reactions catalyzed by beta-cyclodextrin

A facile three-component reaction of aromatic aldehyde, 2,2-dimethyl-1,3-dioxane-4,6-dione, and 6-amino-1,3-dimethyluracil was developed for the first time using beta-cyclodextrin (beta-CD) as a macrocyclic host for aldehyde and an efficient catalyst that leads to a batch of novel pyrano[2,3-d:6,5-d ‘]dipyrimidines (4a-k). The synthesis was accomplished with the aid of microwave irradiations in solvent-free conditions. The product obtained was in contrast to the previous report in which a similar reaction resulted in a mixture of benzylidenepyrimidine and bisaminopyrimidine analogs in the presence of triethylbenzylammonium chloride in an aqueous medium. The formation of the pyrano[2,3-d:6,5-d ‘]dipyrimidines may be in virtue of the property of beta-CD to construct new C-C and C-X (where X = heteroatom) bonds. Reusability of the catalyst up to three runs without any noteworthy change in catalytic activity is one of the main features of the reaction. Other noteworthy features are good to excellent yields, eco-friendly procedure, non-column chromatographic purification, and mild conditions.
