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.

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.

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.

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.

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.

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.

Survival of MS2 and phi 6 viruses in droplets as a function of relative humidity, pH, and salt, protein, and surfactant concentrations

The survival of viruses in droplets is known to depend on droplets’ chemical composition, which may vary in respiratory fluid between individuals and over the course of disease. This relationship is also important for understanding the persistence of viruses in droplets generated from wastewater, freshwater, and seawater. We investigated the effects of salt (0, 1, and 35 g/L), protein (0, 100, and 1000 mu g/mL), surfactant (0, 1, and 10 mu g/mL), and droplet pH (4.0, 7.0, and 10.0) on the viability of viruses in 1-mu L droplets pipetted onto polystyrene surfaces and exposed to 20%, 50%, and 80% relative humidity (RH) using a culture-based approach. Results showed that viability of MS2, a non-enveloped virus, was generally higher than that of phi 6, an enveloped virus, in droplets after 1 hour. The chemical composition of droplets greatly influenced virus viability. Specifically, the survival of MS2 was similar in droplets at different pH values, but the viability of phi 6 was significantly reduced in acidic and basic droplets compared to neutral ones. The presence of bovine serum albumin protected both MS2 and phi 6 from inactivation in droplets. The effects of sodium chloride and the surfactant sodium dodecyl sulfate varied by virus type and RH. Meanwhile, RH affected the viability of viruses as shown previously: viability was lowest at intermediate to high RH. The results demonstrate that the viability of viruses is determined by the chemical composition of carrier droplets, especially pH and protein content, and environmental factors. These findings emphasize the importance of understanding the chemical composition of carrier droplets in order to predict the persistence of viruses contained in them.

Flame retardancy of particleboards made from oil palm trunk-poly(vinyl) alcohol with citric acid and calcium carbonate as additives

Flame retardant particleboards from oil palm trunk particles were made by treatment with sodium chloride solution, then bonded with poly(vinyl) alcohol together with citric acid and calcium carbonate as additives. Flame retardancy, thermal, physical, and mechanical properties were evaluated for suitability as construction materials. The novel flame-retardant oil palm trunk particleboard was successfully produced. Treated oil palm trunk with 20% of poly(vinyl) alcohol and 10% of calcium carbonate showed the highest limited oxygen index (LOI) with good thermal stability and potential to be used as flame-retardant particleboard. Also, salt pre-treatment was found to enhance the flame retardancy of particleboard. (C) 2020 Elsevier Ltd. All rights reserved.

Anoctamin 1 antagonism potentiates conventional tocolytic-mediated relaxation of pregnant human uterine smooth muscle

Background Currently available tocolytic agents are not effective treatment for preterm labor beyond 48 h. A major reason is the development of maternal side effects which preclude the maintenance of an effective steady-state drug concentration. One strategy that can mitigate these side effects is utilizing synergistic drug combinations to reduce the drug concentrations necessary to elicit a clinical effect. We have previously shown that three anoctamin 1 (ANO1) antagonists mediate potent relaxation of precontracted human uterine smooth muscle (USM). In this study, we aimed to determine whether a combination of sub-relaxatory doses of tocolytic drugs in current clinical use [the L-type voltage-gated calcium channel (VGCC) blocker, nifedipine (NIF); and the beta(2)-adrenergic (beta 2AR) agonist, terbutaline (TRB)] will potentiate USM relaxation with two ANO1 antagonists [benzbromarone (BB) and MONNA (MN)]. Objective This study sought to examine the synergistic potency and mechanistic basis of two ANO1 antagonists with currently available tocolytic drugs. Functional endpoints assessed included relaxation of pre-contracting pregnant human USM tissue, inhibition of intracellular calcium release, and reduction of spontaneous transient inward current (STIC) recordings in human uterine smooth muscle cells. Methods Human myometrial strips and primary human USM cells were used in organ bath and calcium flux experiments with different combinations of sub-threshold doses of ANO1 antagonists and terbutaline or nifedipine to determine if ANO1 antagonists potentiate tocolytic drugs. Results The combination of sub-threshold doses of two ANO1 antagonists and current tocolytic drugs demonstrate a significant degree of synergy to relax human pregnant USM compared to the effects achieved when these drugs are administered individually. Conclusion A combination of sub-threshold doses of VGCC blocker and beta 2AR agonist with ANO1 antagonists potentiates relaxation of oxytocin-induced contractility and calcium flux in human USM ex vivo. Our findings may serve as a foundation for novel tocolytic drug combinations.
