Preparation of the novel g-C3N4 and porous polyimide supported hydrotalcite-like compounds materials for water organic contaminants removal

In this work, the novel graphitic carbon nitride (g-C3N4) and porous polyimide (PI) supported calcined hydrotalcite-like compounds (g-C3N4@PI@CHTLcs) were synthesized by co-precipitation and hydrothermal synthesis method, and systematically characterized by physical and chemical methods. The composites showed layered structure and a high thermal stability, and performed well in adsorption of tetracycline (TL), 2, 4-dichlorophenol (DP) and glyphosate (GH). The action pH value was ranged from 7 to 9 for TL and GH, and 3-9 for DP, respectively. The adsorption of TL and DP by g-C3N4@PI@CHTLcs conforms to the pseudo-first-order kinetic model. While for GH, the kinetic data fit well with pseudo-second-order model, indicating chemical adsorption via electrostatic interaction mechanism. Freundlich isothermal could better describe the adsorption process of TL, DP and GH. The maximum adsorption amounts of TL, DP and GH based on Langmuir isotherm model at 298 K were 231.1, 185.05 and 177.34 mg g(-1), respectively. The adsorption processes of TL, DP and GH were all endothermic and spontaneous, and showed excellent repeatability and stability in regeneration experiments. Additionally, the presence of chloride ion and humic acid (HA) showed no obvious effects on the adsorption process of organic contaminants. The diffusion mechanism of TL, DP and GH on the adsorption process was liquid membrane control. The adsorption mechanism might be the ion exchange between the layers of hydrotalcite, and the surface complexation and hydrogen bonding between various groups of PI and organic contaminants. The research showed that g-C3N4@PI@CHTLcs was effective in treatment of water containing various organic pollutants.

Copper-NHC Based Ullmann Catalysis in Water for Selective N-Arylation of 3-Aminophenols

Studies of environmentally benign catalytic methods are of great value in modern chemical synthesis, especially the chemo-selective construction of chemical bonds under green conditions. This work elucidates such preferential synthesis of C-N bond over C-O bond via selective N-arylation of 3-aminophenols using 1,3-bis-[2-hydroxyphenyl] imidazolium chloride (IHPHCl) and copper iodide as catalyst (1 mol %) in aqueous medium. Presence of chelating group (-OH) on IHPHCl enhances N-selectivity. Overall this is a simple and green method for selective N-arylation of 3-aminophenols with good substrate scope and yields (60-88 %). GC-MS, HRMS and other spectroscopic techniques were utilised in detailing the kinetics and mechanistic aspects.

Simple biodegradable plastic screen-printing for microfluidic paper-based analytical devices

The goal of using microfluidic paper-based analytical devices (mu PADs) in remote areas has prompted the development of uncomplicated, affordable, and environmentally-friendly fabrication methods. Here, screen-printed biodegradable polycaprolactone (PCL) as a simple, low-cost, and non-toxic alternative approach to create mu PADs was introduced. No need for a heating step contributed to low PCL dispersion resulting in high resolution hydrophobic barriers. The proposed method achieved a narrowest hydrophilic channel and hydrophobic edge of 510 +/- 40 mu m and 490 +/- 30 mu m, respectively. The method was used to generate several designs for Cr3+ and Cl- detections. For Cr3+ analysis, silver nanoparticles were used as the colorimetric probe to selectively measure Cr3+ using a spot format that achieved a limit of detection (LOD) of 15.0 mu g L-1 and a linear working range of 50.0-1000.0 mu g L-1. For Cr determination, the distance-based pattern using traditional precipitation titration was utilized to resolve the coffee ring effect from colorimetric detection. The method gave an LOD and a linear range for Cr detection of 10.0 mg L-1 and 10.0-500.0 mg L-1, respectively. Finally, the mu PADs were applied for CF analysis in instant noodle seasonings and the results significantly agreed with those using the traditional titration at 95 % confidence.

Voltammetry measurements in lithium chloride-lithium oxide (LiCl-Li2O) salt: An evaluation of working electrode materials

Instrumentation to provide process monitoring (PM) and safeguards for the oxide reduction (OR) step in the electrochemical processing of used oxide nuclear fuel is necessary to ensure equipment is operated as declared. Cyclic voltammetry (CV) has been proposed for real-time monitoring of the operation of an OR process for safeguards purposes. In this study, 316L stainless steel (SS), tantalum (Ta), molybdenum (Mo), tungsten (W), platinum (Pt), and iridium (Ir) were evaluated as potential working electrode (WE) materials based on their chemical inertness, corrosion resistance, and sensitivity in detecting lithium oxide (Li2O) and other chloride salts in the OR electrolyte. Of the electrodes evaluated, 316L SS, Ir, and Pt all performed reasonably well in the lithium chloride-lithium oxide (LiCl-Li2O) electrolyte. SS was operated in the cathodic potential, had reasonable corrosion resistance, and is relatively inexpensive. Ir could be operated in both the cathodic and anodic potentials and was the most corrosion-resistant of the materials evaluated. Pt is limited to the anodic potential range, had reasonable corrosion resistance, and was the most sensitive to Li2O concentrations in the salt. In the development of a stand-alone safeguards instrumentation, our recommendation is a CV probe fitted with both Ir and Pt WEs. The results of this study may also be helpful for anode material selection in other electrometallurgy industries, such as molten salt electrolysis. (C) 2021 Elsevier B.V. All rights reserved.

Anomalous inclusion of chloride ions in ethylenediammonium lead iodide turns 1D non-perovskite into a 2D perovskite structure

In this work, we demonstrate that 1D EDPbli crystals containing face -sharing Pb164- octahedra are synthesized using ethylenediammonium (ED) as an organic cation in hydroiodic acid. However, by the addition of hydrochloric acid to the synthetic solution, 2D [(ED)2Pb14]02 crystals are interestingly constructed without substitution of iodides by chlorides. The importance of chloride ions in the structure has been revealed by employing the single -crystal X-ray diffraction technique. Isolated chlorides, through forming hydrogen bonds with ammonium groups and creating (ED)202z+ templating layers, lessen the interplays between organic cations and inorganic units and consequently lead to the formation of almost undistorted Pb1,2- perovskite layers. The band gaps of the resultant crystals have been determined to be 2.72 eV and 2.30 eV for EDPb14 and [(ED)2Pb14]02, respectively. Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) measurements indicate that both compounds are thermally stable up to 250 C without any phase transition.

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.

Thermo-hydrodynamic analysis of drop impact calcium alginate gelation process

The phenomenon of calcium alginate gel formation from sodium alginate drop impact on calcium chloride liquid pool generates enormous scientific interest. The present work features on the investigation of interfacial heat transfer during sodium alginate drop impact on a heated calcium chloride liquid pool. The liquid pool has been heated at different temperatures varying from 20 degrees C to 70 degrees C. The drop chemically reacts at the interface and calcium alginate gel starts to form which has been instantaneously captured in a high-speed camera. A mathematical model on crater dynamics has been presented to determine the heat transfer coefficient and amount of interfacial heat transfer during the chemical reaction. Now, drop levitation over the vapour layer generated from the evaporation of liquid pool is defined as Leidenfrost pool Effect. This is characterized from the heat transfer at the crater initiation stage and accumulated vapour layer thickness, vapour pressure developed. The release of drop liquid is aided by the surface tension difference between drop and pool at the interface and it is defined as thermal Marangoni Effect. It has been characterized from the variation of Marangoni pressure with temperature which tends to drain away accumulated vapour layer. A critical liquid pool temperature has been obtained when Leidenfrost vapour pressure dominates over Marangoni pressure and resists the drop release during the gel initial regime. The dynamics of calcium alginate gelation is governed by intricate interplay between thermal Marangoni effect and Leidenfrost pool effect with its effect on initial gelation time and total gelation time.

Enhancing the Efficiency and Stability of Triple-Cation Perovskite Solar Cells by Eliminating Excess PbI2 from the Perovskite/Hole Transport Layer Interface

Metal halide perovskites are promising contenders for next-generation photovoltaic applications due to their remarkable photovoltaic efficiency and their compatibility with solution-processed fabrication. Among the various strategies to control the crystallinity and the morphology of the perovskite active layer and its interfaces with the transport layers, fabrication of perovskite solar cells from precursor solutions with a slight excess of PbI2 has become very common. Despite this, the role of such excess PbI2 is still rather controversial, lacking consensus on its effect on the bulk and interface properties of the perovskite layer. In this work, we investigate the effect of removing the excess PbI2 from the surface of a triple-cation mixed-halide Cs-0.05 (FA(0.83)MA(0.17))(0.95)Pb(I0.83Br0.17)(3) perovskite layer by four different organic salts on their photovoltaic performance and stability. We show that treatments with iodide salts such as methylammonium iodide (MAI) and formamidinium iodide (FM) can lead to the strongest beneficial effects on solar cell efficiency, charge recombination suppression, and stability while non-iodide salts such as methylammonium bromide (MABr) and methylammonium chloride (MACI) can also provide improvement in terms of charge recombination suppression and stability to a moderate extent in comparison to the untreated sample. Under optimized conditions and continuous solar illumination, the MAI- and FM-treated devices maintained 81 and 86% of their initial power conversion efficiency (PCEs), respectively, after 100 h of continuous illumination (versus 64% for the untreated solar cell with excess PbI2). Our study demonstrates that eliminating excess PbI2 at the perovskite/hole transport layer (HTL) interface by treating the perovskite surface with organic salts is a simple and efficient route to enhance the efficiency, and in particular the stability of perovskite solar cells.

The late consolidation of an aversive memory is promoted by VTA dopamine release in the dorsal hippocampus

The hippocampus has been implicated in the processing and storage of aversive memories but the precise mechanisms by which these memories persist in time remain elusive. We have demonstrated that dopaminergic neurotransmission in the dorsal hippocampus regulates the long-term storage of both appetitive and aversive memories at a critical time point known as late consolidation (12 hr after the learning experience). This modulation appears to have opposite effects depending on the valence of the stimuli, with hippocampal dopamine release peaking immediately and 13-17 hr after a rewarding experience. Here, we determined the release pattern of hippocampal dopamine following an aversive experience, in order to better understand this opposite modulation process. We observed significant increases in dopamine levels at several times (6-8, 11-12, and 15 hr) after subjecting rats to a conditioned place aversion (CPA) task with the aversive agent lithium chloride (LiCl). Early pharmacological blockade of hippocampal DA receptors impaired CPA memory consolidation. In addition and consistent with previous findings showing that late post-training infusions of dopaminergic agents into the hippocampus modulate the long-term storage of aversive memories, we found that the photostimulation of dopaminergic VTA fibers in the dorsal hippocampus 11-12 hr after CPA training was enough to transform a short-lasting long-term memory into a long-lasting one. The fact that the persistence of an aversive memory can still be affected several hours after the learning experience opens new avenues to develop behavioral and pharmacological strategies for the treatment of a variety of mental disorders.
