Embedded Cluster Study of the Co-Adsorption of HCl and H2O on PuO2 Surfaces

The simultaneous adsorption of HCl and H2O on the {111} and {110} surfaces of PuO2 has been studied using hybrid density functional theory within the periodic electrostatic embedded cluster method. A synergistic effect between co-adsorbed molecules is identified, such that HCl binding energies are enhanced by the presence of water. Higher levels of water also increase the HCl binding energy, forming very stable configurations on both surfaces for first-layer HCl interactions. Second-layer interactions are also explored, in which the HCl molecule is placed above a full monolayer of water on the surfaces. In such circumstances, the HCl reacts with a hydroxyl from the water monolayer to produce molecular water, with the chloride held to the surface via numerous chlorine-acceptor hydrogen bonds.

Bulk ionic screening lengths from extremely large-scale molecular dynamics simulations

Recent experiments have reported anomalously large screening lengths of interactions between charged surfaces confining concentrated electrolytes and ionic liquids. Termed underscreening, this effect was ascribed to bulk properties of dense ionic systems. Herein, we study bulk ionic screening with extremely large-scale molecular dynamics simulations, allowing us to assess the range of distances relevant to the experiments. Our results yield two screening lengths satisfying distinct scaling relations. However, with an accuracy of 10(-5)k(B)T in interionic potentials of mean force, we find no signs of underscreening, suggesting that other than bulk effects might be at play in the experiments.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 50-84-0, you can contact me at any time and look forward to more communication. Recommanded Product: 50-84-0.

Surface sulphide formation on high-temperature corrosion resistant alloys in a H2S-HCl-CO2 mixed atmosphere

In this paper the corrosion behavior of high temperature corrosion resistant alloys is investigated in a gas atmosphere containing HCl and H2S at 480 degrees C and 680 degrees C. By considering the vapor pressures of the metal chlorides and the water gas shift reaction, as well as the influence of H2S, the different corrosion behavior at 480 degrees C compared to 680 degrees C can be explained and a model of the course of corrosion is proposed. Corrosion tests were performed for 240 h with the austenitic stainless steels S31400 (20 wt% Ni) and N08811 (30.4 wt% Ni) and with the Ni-based alloy N06600 (72.5 wt% Ni). It could be shown that with increasing Ni-content in the alloy, the corrosion rate at high temperatures decreased, but this effect could no longer be observed at lower temperatures. While for N08811 and N06600 the mass loss was lower at 680 degrees C, it increased at temperatures of 480 degrees C. In the case of S31400 the mass loss increased with rising temperature.

Characterization of the key taste compounds during bread oral processing by instrumental analysis and dynamic sensory evaluation

The process of taste release and perception during chewing bread was investigated using high-performance liquid chromatography and sodium ion-selective electrode analysis combined with dynamic sensory evaluation. The result of the dynamic quantitative descriptive analysis and temporal dominance of sensation elucidated that sour, salty, and sweet tastes were significantly (P < 0.05) changed during oral processing. The salty taste was the dominant taste at the initial stage of chewing, whereas the sweet taste took the dominant place after 7 s. Seventeen taste-active compounds with the taste activity value more than 1 were identified. According to partial least squares regression analysis, 9 taste compounds were detected as the potent taste compounds contributing to changes in the taste perception during bread oral processing. Malic acid, succinic acid, sodium chloride, valine, and sucrose were confirmed as the key taste compounds contributing to bread oral processing through addition experiments. Malic acid had a stronger enhancing ability of sour and salty perception than succinic acid but weaker inhibition ability to decrease sweet perception than succinic acid.

Fabrication of thin film nanocomposite nanofiltration membrane incorporated with cellulose nanocrystals for removal of Cu(II) and Pb(II)

Thin-film nanocomposite nanofiltration (TFN) membranes were prepared via interfacial polymerization between polyethyleneimine (PEI) and trimesoyl chloride (TMC) with the incorporation of cellulose nanoparticles (CNCs), for the removal of Cu(II) and Pb(II) from aqueous environment. Water contact angle measurements and pure water test showed that the surface hydrophilicity of TFN membranes was improved with the increment of CNCs concentration. Successful deposition of CNCs on the membrane surface was investigated by FTIR analysis. The SEM and AFM results showed that the incorporation of CNCs resulted in a greater surface roughness and a higher surface area to the membranes. The results indicated that the water permeance of TFN membranes increased by 70% compared to a pristine TFC membrane with the CNCs loading mass of 5.5 mu g/cm(2), and also exhibited the acceptable and competitive removal efficiency for toxic heavy metal ions (CuSO4 98.0%, CuCl2 96.5% and PbCl2 90.8%). To the best of our knowledge, this is the pioneering work to study the combination between CNCs and positively charged thin film composite nanofiltration membranes fabricated by interfacial polymerization of polyethyleneimine (PEI) and trimesoyl chloride (TMC) on polyethersulfone (PES) supporting membrane for the rejection of Cu(II) and Pb(II).

Degradation kinetics modeling of antioxidant compounds from the wastes of Mangifera pajang fruit in aqueous and choline chloride/ascorbic acid natural deep eutectic solvent

The fruit wastes of Mangifera pajang were found to exhibit excellent antioxidant capacity. However, its application can be limited by its poor stability. Therefore, this study aims to improve its stability by solubilizing them in a novel choline chloride/ascorbic acid natural deep eutectic solvent (CHCL/AA NADES) system. The degradation of the antioxidant extracts in the aqueous and NADES system under effects of temperature (25 degrees C, 40 degrees C, 60 degrees Cand 80 degrees C) and pH (3.0-8.0) were studied by modeling the degradation kinetics. For both systems, the degradation process followed the first-order kinetics. Remarkably, a lower degradation rate constant was found for the antioxidant-CHCL/AA NADES system, suggesting the ability of CHCL/AA NADES in protecting the antioxidant against extreme temperature and pH. Moreover, the half-life values for the antioxidant-CHCL/AA NADES was higher by 4.17-25% as compared to the antioxidant-aqueous system, suggesting that the CHCL/AA NADES is feasible to improve the stability of antioxidants.

Doped Bilayer Tin(IV) Oxide Electron Transport Layer for High Open-Circuit Voltage Planar Perovskite Solar Cells with Reduced Hysteresis

Tin oxide (SnO2) is an emerging electron transport layer (ETL) material in halide perovskite solar cells (PSCs). Among current limitations, open-circuit voltage (V-OC) loss is one of the major factors to be addressed for further improvement. Here a bilayer ETL consisting of two SnO2 nanoparticle layers doped with different amounts of ammonium chloride is proposed. As demonstrated by photoelectron spectroscopy and photophysical studies, the main effect of the novel ETL is to modify the energy level alignment at the SnO2/perovskite interface, which leads to decreased carrier recombination, enhanced electron transfer, and reduced voltage loss. Moreover, X-ray diffraction reveals reduced strain in perovskite layers grown on bilayer ETLs with respect to single-layer ETLs, further contributing to a decrease of carrier recombination processes. Finally, the bilayer approach enables the more reproducible preparation of smooth and pinhole-free ETLs as compared to single-step deposition ETLs. PSCs with the doped bilayer SnO2 ETL demonstrate strongly increased V-OC values of up to 1.21 V with a power conversion efficiency of 21.75% while showing negligible hysteresis and enhanced stability. Moreover, the SnO2 bilayer can be processed at low temperature (70 degrees C), and has therefore a high potential for use in tandem devices or flexible PSCs.

Evaluation of corrosion resistance of the single-phase light refractory high entropy alloy TiCrVNb0.5Al0.5 in chloride environment

A low density refractory high entropy alloy of composition TiCrVNb0.5Al0.5 was prepared by vacuum arc melting. Due to the formation of a single-phase BCC structure with uniform element distribution and a gradient passive film with a high concentration of passivating elements, the TiCrVNb0.5Al0.5 high entropy alloy (HEA) exhibits low corrosion current density (10(-7) similar to 10(-8) A cm(-2)), high breakdown potential (1.8-1.9 V-SCE) and excellent repassivation ability in 3.5 wt% NaCl and 1M HCl solutions. The properties were compared with HEAs, bulk metallic glasses (BMGs) and traditional alloys reported in literatures. The results show that TiCrVNb0.5Al0.5 possesses the most outstanding corrosion resistance in chloride environment. (C) 2020 Elsevier B.V. All rights reserved.

Recent Advances in Halogen Bonded Assemblies with Resorcin[4]arenes

Resorcinarenes are cavity-containing compounds when in the crown conformation, from the calixarene family of concave compounds. These easy to synthesize macrocycles can be decorated at the upper rim through the eight hydroxyl groups and/or the 2-position of the aromatic ring. They are good synthons in supramolecular chemistry leading to appealing assemblies such as open-inclusion complexes, capsules and tubes through multiple weak interactions with various guests. Halogen bonding (XB) is a highly directional non-covalent interaction by an electron-deficient halogen atom as a donor that interacts with a Lewis base, the XB acceptor. This tutorial review provides an overview of recent advances in halogen-bonded assemblies based on resorcinarenes and their derivatives, specifically focusing on discrete and capsular assemblies.
