Accelerated nucleophilic substitution reactions of dansyl chloride with aniline under ambient conditions via dual-tip reactive paper spray

Paper spray ionization (PSI) mass spectrometry (MS) is an emerging tool for ambient reaction monitoring via microdroplet reaction acceleration. PSI-MS was used to accelerate and monitor the time course of the reaction of dansyl chloride with aniline, in acetonitrile, to produce dansyl aniline. Three distinct PSI arrangements were explored in this study representing alternative approaches for sample loading and interaction; conventional single tip as well as two novel setups, a dual-tip and a co-axial arrangement were designed so as to limit any on-paper interaction between reagents. The effect on product abundance was investigated using these different paper configurations as it relates to the time course and distance of microdroplet travel. It was observed that product yield increases at a given distance and then decreases thereafter for all PSI configurations. The fluorescent property of the product (dansyl aniline) was used to visually inspect the reaction progress on the paper substrate during the spraying process. Amongst the variety of sample loading methods the novel dual-tip arrangement showed an increased product yield and microdroplet density, whilst avoiding any on-paper interaction between the reagents.

Enhancement of the thermal analysis of power cables installed in polyvinyl chloride (PVC) ducts under continuous and cyclic current loading conditions

A study of the performance of power cables installed inside non-metallic ducts is presented here. Cable capacity calculations for this type of installation are done. The thermal analysis of cables inside ducts which are installed in air as riser or buried in soils is presented. According to IEC 60287 cables can be installed in fibre ducts in concrete layer surrounded by the soil, in this article it is proposed to install the cables in PVC ducts directly buried in the soil. Based on IEC 60287-1-3 and IEC 60853-2 standards proposed models in steady state and dynamic cable loadings are constructed. The proposed equivalent thermal models are used in the calculations of the cable components temperature for cables installed in ducts. It is concluded that very high increase in cable conductor temperature is observed when the cable is installed in duct and used as riser or even when it is installed in duct buried in soil. Significant decrease in the temperature of the cable conductor can be noticed when the cable is directly buried in the soil compared with that installed in ducts.

Retention of anions in cobalt hydroxide with Ni substitution to emphasize the role of anions and cations for high current density in oxygen evolution reactions

Herein, we report the fabrication of remarkably fine nickel-substituted alpha-Co(OH)(2) sheets using an ingenious co-precipitation method at a lower pH value. An alpha-CoNiOOH sheet retains the parent alpha-Co(OH)(2) structure consisting of both tetrahedral (Td) and octahedral (Oh) sites with the retention of interlayer chloride ions, which is in contrast to the previous reports. The as-synthesized alpha-CoNiOOH sheet exhibits excellent oxygen evolution reactions (OERs) and produces a current of 10 mA cm(-2) at an overpotential of merely 190 mV in an alkaline environment. Moreover, the alpha-CoNiOOH sheet attains an exceptionally high current density of 100 mA cm(-2) at a low overpotential of only 270 mV. Additionally, this electrocatalyst possesses a 33 mV dec(-1) Tafel slope with higher values of TOF (11 s(-1)) and double-layer capacitance (7.76 mF cm(-2)). This enhancement is attributed partially to the substitution of Ni during the conversion of alpha-Co(OH)(2) to alpha-CoNiOOH and partially to the exceptionally thin sheets allowing potential octahedral sites for improved oxygen evolution reactions.

Enhanced optical cross-section of radiation induced defect centers under plasmon resonance conditions: Shifting stimulation wavelength of optically stimulated luminescence dosimeters

Plasmon-enhanced luminescence is an important tool for development of advanced sensing technologies but the mechanisms originating these enhancements are still in debate. In this work, we investigate plasmon-enhanced luminescence mechanisms using the Optically Stimulated Luminescence (OSL) from defect centers in X-ray irradiated sodium chloride nanocrystals deposited on silver nanoparticle (AgNP) films with varying plasmon properties upon blue, green, and red OSL stimulation. Although the absolute OSL intensity for NaCl crystals is higher upon blue stimulation, under plasmon resonance conditions, higher absolute OSL intensity occurs upon green stimulation and the largest OSL enhancements are observed by employing red stimulation. These results suggest that, as long as the OSL stimulation wavelength is well tuned with the film plasmon band, plasmonic coupling does not depend on the trap depth and that the largest luminescence enhancements are achieved in spectral regions where the optical cross-sections of the defect centers are smaller. In terms of radiation dosimetry applications, this result allows to shift the stimulation wavelength farther from the OSL emission window, improving the signal to noise ratio and the dose assessment sensitivity and accuracy.

Chloride Diffusion and Induced Reinforcement Corrosion in Concrete with Fly Ash and Ground-Granulated Blast-Furnace Slag Exposed to Marine Submerged Zone(1)

This paper investigates the influence of mineral admixtures fly ash (FA) and ground-granulated blast-furnace slag (GGBS), the byproducts of industry, on chloride ions migration and corrosion resistance performance. A novel preparation method of wire beam electrode (WEB) was also introduced to explore the excellent corrosion-resistant capacity of concrete with mineral admixtures. By comparing concrete specimens with and without FA and GGBS, the test result of wire beam electrode, rapid chloride migration (RCM), and electrochemical tests highlight the positive impact of fly ash and GGBS against chloride ions migration, respectively. Concrete with fly ash and GGBS supplies an advanced protection effect of ordinary Portland cement; meanwhile, CO2 emission amount can be significantly reduced. Moreover, homemade wire beam electrode was proved to be a novel and reliable test method against corrosion, which has agreement with the test result of an electrochemical device.

Kraft Lignin Solubility and Its Chemical Modification in Deep Eutectic Solvents

Lignin stands as a promising raw material to produce commodities and specialty chemicals, yet its poor solubility remains a big challenge. Recently, deep eutectic solvents (DES) have been proposed as sustainable solvents with high potential to dissolve and valorize lignin. In the present study, the ability of DES based on cholinium chloride ([Ch]Cl) combined with alcohols and carboxylic acids as hydrogen bond donors (HBDs) to dissolve kraft lignin and to change its chemical structure was examined. The influence of the chemical nature of HBDs, water content, and HBD:hydrogen bond acceptor (HBA) molar ratio on the solubility of kraft lignin in DES was studied (313.15 K). The kraft lignin solubility was enhanced by increasing both the HBD’s carbon chain length and the molar ratio, with [Ch]Cl:HEXA (1,6-hexanediol) and [Ch]Cl:MaleA (maleic acid) being the best studied solvents for kraft lignin dissolution, while the addition of water was a negative factor. The thermal treatments (393.15 K) of kraft lignin show that carboxylic acid-based DES promote chemical modifications to kraft lignin, including the disruption of several C-O covalent type bonds (e.g., beta-O-4, alpha-O-4 and alpha-O-alpha), while alcohol-based DES were found to be nonderivatizing solvents maintaining the lignin chemical structure. These results show the versatility of DES, which, depending on their chemical nature, may offer distinct strategies for lignin valorization.

Consequence of Galvanic Displacement Reaction on Digital Photocorrosion of GaAs/Al0.35Ga0.65As Nanoheterostructures

GaAs/AlGaAs semiconductor nanoheterostructures have found attractive application in the field of biosensing based on the effect of digital photocorrosion (DIP). The sensitivity of semiconductor-nanoheterostructure-based biosensors depends on the precision of controlling the process of DIP, which is highly sensitive to the surface presence of electrically charged biomolecules. To explore further this process, we have investigated the role of a galvanic displacement (GD) reaction on DIP of GaAs/Al0.35Ga0.65As (001) nanoheterostructures. Deposition of ionic gold on the GaAs surface induces spontaneous electron transfer between the semiconductor and ionic gold, which affects the photocorrosion of GaAs/AlGaAs layers observed simultaneously with the photoluminescence effect. The immediate consequence of the electron transfer from GaAs toward Au3+ is a significantly increased rate of DIP. At the same time, the formation of neutralized gold nanoparticles and Au-Ga alloy takes place on the surface of photocorroding nanoheterostructures. In the presence of 2.8% solution of ammonia and 0.1 mM gold chloride, a significantly reduced rate of deposition of gold nanoparticles is observed. This allows achieving layer-by-layer removal of the investigated material, which is sensitive to perturbations induced by surface immobilized electrically charged molecules. We have elaborated various factors stimulating photocorrosion of the GaAs/Al0.35Ga0.65As nanoheterostructures and we demonstrate the biosensing potential of an innovative GD-based DIP sensor.

Characterization of surface films on constructional steel in carbonated media containing chloride and nitrite ions

The inhibition effect of NaNO2 on the electronic properties of the passive film was investigated for carbon steel exposed to solutions of pH=13 and pH= 9 keeping the ratio [inhibitor]/[chloride]=1. Cyclic voltammograms, polarization curves, electrochemical impedance spectroscopy, Mott-Schottky plots and Xray photoelectron spectra were analyzed. Steel is passive at pH=13 and active at pH=9 (carbonated solutions). Passivity can be regained in carbonated solutions when nitrite ions are also present. The thickness and composition of the surface films depend on alkalinity. Both films behave as n-type semiconductors. Donor density values are similar for films grown in solutions containing nitrite ions, regardless of the presence of carbonate ions and the difference in alkalinity. Nitrite ions inhibit pitting in both solutions, although the difference between pitting and open circuit potentials is 2.7 times higher at pH=13. Donor density values cannot be used as the single parameter to evaluate pitting risk. (C) 2020 Elsevier Ltd. All rights reserved.

Hydrophobic thermoplastic starch supramolecularly-induced by a functional sucrose based ionic liquid crystal

It is still a big challenge to obtain hydrophobic thermoplastic starch with outstanding mechanical performance due to the inevitable usage of typical hydrophilic plasticizers like glycerol during processing. Herein, we report a novel hydrophobic thermoplastic starch using a supramolecularly induced thermoplasticization technique. To achieve this aim, a functional sucrose-based ionic liquid crystal (ILC) including numerous chloride atoms has been firstly synthesized, and the obtained ILC molecules are then used as supramolecular inducers to thermoplasticize corn starch granules. Thermoplasticity and hydrophobicity of the prepared supramolecularly induced thermoplastic starch (STPS) with different ILC contents have been extensively investigated. Mechanism of the supramolecularly induced thermoplasticization has been investigated using molecular simulation as well. The prepared STPS with the maximum tensile strength of 8.4 MPa and water contact angle of about 117 degrees show large potential applications in green and sustainable packaging materials.

Ammonium produced from Shewanella strain 0409 contributes to antiviral activity against Betanodavirus

Nervous necrosis virus (NNV) (genus: Betanodavirus) attacks aquacultured fish. Biocontrol may prevent and control the disease caused by NNV infection. Shewanella strain 0409 was isolated from the micmbiome of grouper intestines, and its culture supernatant (CS0409) could inhibit NNV replication in vitro. The present study elucidated the antiviral mechanism of Shewanella strain 0409 against NNV in vitro. In NNV-infected GF-1 cells, CS0409 reduced both NNV RNA synthesis and the percentage of cells expressing NNV RNA-dependent RNA polymerase (RdRp) within 24 hpi. However, NNV RdRp activity was not inhibited by CS0490 treatment. The most favorable time for CS0409 treatment in NNV-infected GF-1 cells was the period of viral adsorption, which revealed a high inhibition level of NNV RNA synthesis. Shewanella strain 0409 produced ammonium in CS0409. When ammonium in CS0409 was removed by heating with evaporation, the anti-NNV activity of CS0409 decreased. Moreover, ammonium in CS0409 inhibited the acidification of acidic organelles. Furthermore, the morphology of NNV virions changed to empty particles after exposure to pH 5 and 6, indicating that NNV uncoating required the acidic environment of endosomes. Therefore, ammonium in CS0409 is responsible for the anti-NNV activity in vitro by inhibiting the acidification of endosomes and then suppressing NNV uncoating.
