Rapid, sensitive, and selective copper (II) determination using sensitive chromogenic azo dye based on sulfonamide

A simple methods have been developed for determination of Cu(II) ions in aqueous solutions. The spectrophotometric method relied mainly on the reaction between Cu(II) ions and the azo dye ligand named N-diaminomethylene-4-(2,4-dihydroxy-phenylazo)-benzenesulfonamide (H2L) at pH 10.0. The influence of parameters such as concentration, pH and reaction time were inspected. A linear relationship (R-2 = 0.9992) between absorbance and the concentration of Cu(II) was obtained at the maximum absorption peak of 474 nm within 1.6-9.6 x 10(-6) mol L-1 concentration range. The limit of detection for Cu(II) ion and limit of quantitation were 1.1 x 10(-7) mol L-1 and 3.7 x 10(-7) mol L-1, respectively. The potentiometric method is based on a novel poly(vinyl chloride) membrane, containing the synthesized azo dye as an ionophore, was used to developed a Cu(II)selective sensor. This newly developed sensor revealed a Nernstian response over Cu2+ ion in a concentration range 1.0 x 10(-6) 1.0 x 10(-2) mol L-1 with cationic slopes of 29.5 +/- 0.2 mV decade(-1) and detection limits of 3.0 x 10(-6) mol L-1 copper(II) for o-nitrophenyloctyl ether (o-NPOE) based membrane sensor. The electrode showed good discrimination toward Cu2+ ions with respect to most common cations. The advantages of the proposed methods are their simplicity, selectivity, and high sensitivity. In addition, the sensor has been used as indicator electrode in the potentiometric titration of Cu2+ ion against EDTA. The structure and geometry of the complex formed between Cu(II) and H2L ligand was identified via isolation of the solid complex; Co(II) an Ni(II) complexes were synthesized as well. The geometrical structure around the metal centers were proved to be square planar for Cu(II) complex and tetrahedral for Co(II) an Ni(II) complexes. (C) 2020 Elsevier B.V. All rights reserved.

Stability of Proton Exchange Membranes in Phosphate Buffer for Enzymatic Fuel Cell Application: Hydration, Conductivity and Mechanical Properties

Proton-conducting ionomers are widespread materials for application in electrochemical energy storage devices. However, their properties depend strongly on operating conditions. In bio-fuel cells with a separator membrane, the swelling behavior as well as the conductivity need to be optimized with regard to the use of buffer solutions for the stability of the enzyme catalyst. This work presents a study of the hydrolytic stability, conductivity and mechanical behavior of different proton exchange membranes based on sulfonated poly(ether ether ketone) (SPEEK) and sulfonated poly(phenyl sulfone) (SPPSU) ionomers in phosphate buffer solution. The results show that the membrane stability can be adapted by changing the casting solvent (DMSO, water or ethanol) and procedures, including a crosslinking heat treatment, or by blending the two ionomers. A comparison with Nafion(TM) shows the different behavior of this ionomer versus SPEEK membranes.

Kraft Lignin Ethanolysis over Zeolites with Different Acidity and Pore Structures for Aromatics Production

To utilize its rich aromatics, lignin, a high-volume waste and environmental hazard, was depolymerized in supercritical ethanol over various zeolites types with different acidity and pore structures. Targeting at high yield/selectivity of aromatics such as phenols, microporous Beta, Y, and ZSM-5 zeolites were first examined in lignin ethanolysis, followed by zeolites with similar micropore size but different acidity. Further comparisons were made between zeolites with fin-like and worm-like mesoporous structures and their microporous counterparts. Despite depolymerization complexity and diversified ethanolysis products, strong acidity was found effective to cleave both C-O-C and C-C linkages of lignin while mild acidity works mainly in ether bond breakdown. However, when diffusion of gigantic molecules is severe, pore size, particularly mesopores, becomes more decisive on phenol selectivity. These findings provide important guidelines on future selection and design of zeolites with appropriate acidity and pore structure to promote lignin ethanolysis or other hydrocarbon cracking processes.

The Emerging Physiological Role of AGMO 10 Years after Its Gene Identification

The gene encoding alkylglycerol monooxygenase (AGMO) was assigned 10 years ago. So far, AGMO is the only known enzyme capable of catalysing the breakdown of alkylglycerols and lyso-alkylglycerophospholipids. With the knowledge of the genetic information, it was possible to relate a potential contribution for mutations in the AGMO locus to human diseases by genome-wide association studies. A possible role for AGMO was implicated by genetic analyses in a variety of human pathologies such as type 2 diabetes, neurodevelopmental disorders, cancer, and immune defence. Deficient catabolism of stored lipids carrying an alkyl bond by an absence of AGMO was shown to impact on the overall lipid composition also outside the ether lipid pool. This review focuses on the current evidence of AGMO in human diseases and summarises experimental evidence for its role in immunity, energy homeostasis, and development in humans and several model organisms. With the progress in lipidomics platform and genetic identification of enzymes involved in ether lipid metabolism such as AGMO, it is now possible to study the consequence of gene ablation on the global lipid pool and further on certain signalling cascades in a variety of model organisms in more detail.

Activated potassium ions as CO2 carriers for PEBAX-5513/KBF4 composite membranes

This study showed that potassium tetrafluoroborate (KBF4) could be used as a carrier to facilitate the transport of CO2. A polymer electrolyte membrane was prepared by incorporating KBF4 into poly (ether-block-amide) (PEBAX-5513) with a flexible PE group. The prepared PEBAX-5513/KBF4 electrolyte membrane exhibited CO2 separation performance that was improved by nine times compared to pure PEBAX-5513 and by about seven times compared to a PVP/KF electrolyte membrane. The membrane exhibited a selectivity of 27.9. This improved separation performance increased the transport of CO2 owing to the reversible interaction of the dissociated potassium ions with CO2 molecules. The dissociation of potassium ions upon thermal treatment of the material was confirmed by Fourier transform Raman spectroscopy, and the selective layer in which the separation mechanism was generated was confirmed by scanning electron microscopy.

Heterogeneous ozonation of ofloxacin using MnOx-CeOx/gamma-Al2O3 as a catalyst: Performances, degradation kinetics and possible degradation pathways

In this study, the performance of ofloxacin (OFX) degradation in synthetic wastewater using synthesized MnOx-CeOx/gamma-Al2O3 as a heterogeneous ozonation catalyst was evaluated. The removal rates of OFX and chemical oxygen demand (COD) during 15-day continuous-flow experiments were 98.2% and 76.7% on average, respectively. An ozone index (mgCOD/mgO(3)) of 1.09 with a high ozone utilization efficiency of 91.39% was achieved. The pseudo-first-order rate constant of ofloxacin degradation reached 15.216 x 10(-2) min(-1), which was five times that (3.085 x 10(-2) min(-1)) without catalysts. The results of gas chromatography-mass spectrometry (GC-MS) demonstrated that a variety of small-molecule organics occurred in the final oxidation products, such as 4-hydroxyl-4-methyl-2-pentanone and 2-oxoadipic acid in addition to homologs of OFX. The results of this study suggested that hydroxyl radicals played critical roles in the degradation and mineralization of OFX via four main pathways: (a) electrophilic addition of nitrogen; (b) breakdown of carbon-carbon double bonds; (c) hydrolysis of ether rings; and (d) halodecarboxylation of carboxyl groups. The biodegradability (BOD5/COD) of OFX after catalytic ozonation reached 0.54. Practitioner points Ofloxacin wastewater was treated using catalytic ozonation in a 15-day continuous experiment with MnOx-CeOx/gamma-Al2O3 as a catalyst. The ozone index reached 1.09 mgCOD/mgO(3) during ozonation of ofloxacin. The presence of the catalyst increased the reaction rate constant by a factor of five. 4-hydroxy-4-methyl-2-pentanone was the primary ofloxacin oxidation product.

Lithiated polyanion supported Li1.5Al0.5Ge1.5(PO4)(3) composite membrane as single-ion conducting electrolyte for security and stability advancement in lithium metal batteries

Polymer electrolytes with single ion conducting behavior, high ion conductivity and fire-resistant play a vital role in suppressing lithium dendrite growth for high security, stability and high energy density of rechargeable lithium metal batteries (LMBs). Herein, we develop a gel single-ion composite electrolyte (SICE) by incorporating Li1.5Al0.5Ge1.5(PO4)(3) nanoparticles into alternating diblock lithiated bis(benzene sulfonyl)imide polyanion with repeating ether groups. Li1.5Al0.5Ge1.5(PO4)(3) nanoparticles can significantly endow SICE membrane more Li+ transportation channels, which offers elevated ionic conductivity (8.3 x 10(-4) S cm(-1)) and Li+ transference number (0.93) to promote homogenously Li+ deposition in lithium foil for dendrite suppression. As a result, a highly reversible Li plating/stripping in a Li symmetric cell enables to run stably for at least 1600 h at 0.5 mA cm(-2). Furthermore, Li1.5Al0.5Ge1.5(PO4)(3) nanoparticles increases the electrochemical window of SICE up to 4.6 V (vs. Li+/Li), meanwhile enhances the thermal stability and fire-resistance, and promotes fast electrolyte wetting. Accordingly, a single-ion conducting LiFePO4/Li cell assembled with optimized SICE membrane endowed a high capacity retention of 92.9% after 800 cycles at 1 C, superior to the commercial LiPF6/PP system. This work paves a scalable and deployable way for design of advanced single-ion conducting electrolyte membranes to develop secure and stable LMBs.

Dimensionally and oxidatively stable anion exchange membranes based on bication cross-linked poly(meta-terphenylene alkylene)s

Anion exchange membrane (AEM) is a key component for energy-conversion devices that enabling the use of non-noble electrocatalysts. After more than a decade of pursuit in alkaline-stable and high anion-conducting ionomers, aryl ether-free polyaromatics offer a promising candidate as an advanced AEM for use in fuel cell and electrolyzers. However, the traditional trade-off dilemma between conductivity and stability (e.g., chemical, dimensional, and mechanical stabilities etc.) of the membrane still remains. Here, we introduced a flexible bication cross-linker to doubly quaternary ammonium-tethered poly(meta-terphenylene alkylene) ionomers with high ion contents, aiming to improve the chemical and dimensional stabilities without compensate the ion-conducting merits. The designed flexible bication cross-linker is responsible for the microphase-separated morphology preservation in the cross-linked membranes. Although the water absorption decreased significantly as cross-linking content increasing, the ion conductivity of the cross-linked AEM was well retained, especially at elevated temperatures. Moreover, after cross-linking, a notable increase in chemical stability was observed, and the m-XPTPA40-2N with highest cross-linking density exhibited the best alkaline and oxidative stabilities. Owing to the mechanical robustness and high conductivity, a fuel cell fabricated with cross-linked membrane m-XPTPA40-2N showed a maximum power density of 302 mW cm(-2) at a current density of 614 mA cm(-2). Overall, the results of this study provide a simple but efficient strategy to improve the performance of AEM.

Homogeneous Composite Nonwoven Support for High Temperature-Resistant Separation Membranes

High temperature-resistant separation membranes are widely considered in various fields. However, incompetent support layer limits the performance of high temperature-resistant membranes severely. In this work, a homogeneous composite nonwoven support (HCNS) is developed by wet-laid and hot-pressing technology using undrawn polyethylene terephthalate fibers as bonding fibers. The significance of hot-pressing parameters on the performances of the HCNS is investigated, and quadratic regression models are established. The HCNS exhibits a smooth surface (roughness of 118 nm) and a porous structure (porosity of 21.06% and pore size of 6.548 mu m) with a mechanical property (tensile index of 45.80 N m g(-1)). The ultrafiltration membranes supported by the HCNS are prepared from poly(phthalazine ether sulfone ketone), which demonstrates high permeance, high rejection rate, and long-term stability at raised operation temperature, thereby suggesting the potential application of HCNS in high-temperature filtration.

Poly ether ether ketone and its composite powder prepared by thermally induced phase separation for high temperature selective laser sintering

Selective Laser Sintering (SLS) is one of the advanced additive manufacturing technologies which can build the geometrically complex structure from a three-dimensional CAD model. Poly ether ether ketone (PEEK) is one of the available materials for SLS and has received numerous interesting due to its excellent properties. In this research, a novel approach, thermally induced phase separation (TIPS) was employed to produce neat PEEK and PEEK/CNT composite powders with near spherical shape, desired particle size and size distribution for SLS application. Powders produced by TIPS demonstrated good flowability and processability. SEM images proved that CNT was embedded in PEEK powder. PEEK/CNT composite powder had shown an increased crystallinity in comparison with neat PEEK powder. Sintering rate of produced powders were studied with hot stage microscopy. Single layer films were built successfully by high temperature selective laser sintering (HT-SLS) using the powder developed via TIPS. Thermodynamics characteristics of single layer films were studied by DMA. Results revealed that addition of 0.1% CNT improved both storage and loss modulus of PEEK. (c) 2021 The Authors.
