Four new coordination complexes prepared for the degradation of methyl violent dye based on flexible dicarboxylate and different N-donor coligands

A ether-bridged dicarboxylic acid, 4,4′-{[1,2-phenylenebis-(methylene)]bis(oxy) dibenzoic acid (H2L), was used as highly versatile building block for the hydrothermal generation of a series of coordination polymeric architectures in thepresence of 1,1′-(1,4-butanediyl)bis(imidazole) (bbi) and 1,10-phenanthroline (phen). These were formulated as [Co-2(L)(2)(bbi)center dot CH3CN](n) (1), [Cu(L)(bbi)](n) (2), [Co(L)(phen)(H2O)](n) (3), and [Cu(L)(phen)(H2O)center dot 2CH(3)CN](n) (4), have been synthesized and characterized. Thenature of the N-donor building blocks and metal ions have a significant effect on the structural diversity. Photocatalytic properties of selected materials were investigated, showing that 2is a promising photocatalyst for the UV-light driven degradation of methyl violet (MV) as a model organic dye pollutant.

Modulatory Role of Vitamin E on Proton Pump (ATPase) Activity of Cadmium Chloride-Induced Testicular Damage in Wistar Rats

Proton pumps are membrane-bound enzymes important in generating gradients that help in maintaining cellular ion homeostasis, cell membrane potential, water, and solute transport across the cell surface. This study investigated the modulatory role of vitamin E on proton pump activity and reproductive parameters in cadmium-induced testicular damage. Twenty (20) male Wistar rats weighing between 180 and 200 g were sorted into 4 groups of five rats each. Group I served as the control and was given normal saline orally, Group II rats were treated with a single dose of 2 mg/kg BW cadmium chloride (CdCl2) intraperitoneally, Group III rats were given 100 mg/kg BW of vitamin E orally, and Group IV rats were given 100 mg/kg BW of vitamin E orally for 30 days prior to intraperitoneal administration of single dose of 2 mg/kg BW of cadmium chloride. The rats were anaesthetized with diethyl ether, and blood samples were obtained for sex hormonal analysis; caudal epididymis was dissected for sperm count, motility, and viability, and the testis were homogenized for lipid peroxidation and proton pump (Na+/K+ ATPase, Ca2+ ATPase, and Mg2+ ATPase) activity. Proton pump activity was assayed spectrophotometrically using the Stewart method to determine the inorganic phosphate level. Histopathological changes of the testis were also studied. The group treated with CdCl2 showed a significant (p<0.05) decrease in proton pump activity, sperm count, and motility and a significant (p<0.05) increase in malondialdehyde level when compared with the control group. The CdCl2-treated group also showed decrease reproductive organ weights and hormonal levels and cause necrosis of spermatogonia lining the seminiferous tubules. Rats treated with vitamin E orally for 30 days prior to CdCl2 exposure showed improvement in proton pump activity, a significant (p<0.05) increase in sperm parameters and luteinizing hormonal level, and a decrease in the lipid peroxidation level as compared with the CdCl2 group. This study showed that vitamin E ameliorated the toxic effect of CdCl2 on proton pump activity in the testes, hence improving testicular integrity, structures, and functions.

Dendrite-Free and Long-Cycling Sodium Metal Batteries Enabled by Sodium-Ether Cointercalated Graphite Anode

Stable and dendrite-free Na metal plating-stripping is achieved on the graphite electrode. The sodium-ether cointercalated graphite exhibits ultrahigh Na deposition efficiency of 99.86% over 900 cycles at a current density of 2 mA cm(-2). The discharge process involves the [Na-ether](+) cointercalation and Na deposition. Density functional theory calculations demonstrate that the cointercalated graphite is critical for uniform Na deposition and stable Coulombic efficiency, which is ascribed to both the robust binding sites to Na by the diglyme molecules and a low lattice mismatch for Na growth on the cointercalated graphite. Also, a full cell consisting of Na4Fe3(PO4)(2)(P2O7) cathode and 0.5 mAh cm(-2) Na predeposited graphite anode shows excellent cycling stability. The full cell delivers a capacity of 95 mAh g(-1) based on the weight of cathode materials, with a high capacity retention of 91% over 300 cycles.

Investigating the effect of water-mixing nitrogen atmospheric pressure plasma jet on polyether-ether-ketone and time stability under different conditions

Possessing excellent properties including good biocompatibility, high strength, and stiffness, polyether-ether-ketone (PEEK) has significant application values in medical and industrial fields. However, the relatively poor wettability and low adhesion limit its further applications. Atmospheric pressure plasma jet (APPJ) has been utilized for adjusting PEEK properties, but better hydrophilization effect and time stability after treatment are still urgently needed. In this paper, we employ a water-mixing nitrogen (N-2-H2O) APPJ to process PEEK, and surface wettability can be effectively improved (contact angle similar to 18 degrees within 2 min, distance between sample and nozzle outlet: 10 mm) without inducing obvious microstructure damages. Additionally, after storing for 40 days, the sample treated by N-2-H2O APPJ also possessed better wettability (similar to 54 degrees) compared with that treated by N-2 APPJ (similar to 65 degrees). On the basis of this low-damage and high-efficient modification method, we perform aging experiments under different conditions (different temperatures 25, -10 degrees C; and low vacuum condition: 50 kPa) to determine a relatively optimum storing condition for this method. The experiment results indicate that low temperature and vacuum are conducive to retaining the plasma-induced wettability (similar to 34 degrees). The treatment method and storing conditions for PEEK presented here may facilitate the application of PEEK in various fields.

Shear driven deformation and damage mechanisms in High-performance carbon Fibre-reinforced thermoplastic and toughened thermoset composites subjected to high strain loading

High strain loading response of high-performance aerospace grade polyether-ether-ketone (PEEK) and toughened epoxy carbon fibre-reinforced composites has been investigated in pre-impregnated laminates having identical carbon fibre volume fraction, i.e. nearly 65%. Tensile cyclic loading tests have been carried out on the laminates with [ +/- 45 degrees](8S) stacking sequence, in order to characterise inelastic (plasticity) parameters for the two laminates progressively up to high strains (up to 11% strains), in correlation with the fibre and matrix micro-scale deformation and damage characteristics. The most suitable processes to achieve ultimate mechanical performance were used for manufacturing of the laminates. It has been observed that the PEEK composite exhibits higher mechanical performance at high strains under cyclic loads compared to epoxy composites (150% ultimate failure strain, 380% strain hardening and 200% ultimate failure stress) due to having superior micro-scale shear deformation in PEEK attributed to interfacial strength of fibre-matrix prior to the ultimate failure, as opposed to extensive micro-cracking, coalescence and fibre-matrix debonding in the epoxy composite.

Pressure and temperature effect on hypergolic ignition delay of triglyme-based fuel with hydrogen peroxide

In this study the effect of fuel temperature and environmental pressure on hypergolic ignition delay of triglyme (triethylene glycol dimethyl ether) with the addition of sodium borohydride and hydrogen peroxide was investigated. The research was conducted in a constant volume chamber using a drop-test method where the oxidizer drop was released into the fuel pool. The environmental pressure (absolute) was 0.1, 0.5, 1, 1.5 and 2 MPa; while the fuel temperature was 22, 40 and 60 degrees C. The main advantage of this study is that the effects of pressure and temperature were not investigated separately but the tests were done for full matrix conditions. This allowed the evaluation of the effect of fuel temperature at ambient and elevated pressures, and the effect of environmental pressure for ambient and elevated fuel temperatures, based on direct ignition delay measurements, a unique feature of this research. Additionally, the dispersion of the results was analysed in terms of repeatability of droplet parameters i.e. Weber number, as well as the diameter and velocity separately, along with eccentricity. The results have shown a huge influence on the ignition delay of both the fuel temperature and the environmental pressure. It was noticed that the average values of the Weber number and the droplet eccentricity remained at a similar level for all measurement points.

Chemical characterization of billy goat weed extracts Ageratum conyzoides (Asteraceae) and their mosquitocidal activity against three blood-sucking pests and their non-toxicity against aquatic predators

The petroleum ether crude extracts of A. conyzoides (Pe-Ac) were used to treat three medically intimidating pests of Aedes aegypti, Anopheles stephensi, and Culex quinquefasciatus, to evaluate their non-target screening against the mosquito predator. The chemical scanning of Pe-Ac through GC-MS analysis revealed a total of nine compounds and the maximum peak area was observed in 1,5-Heptadien-3-yne (22.14%). At the maximum dosage of Pe-Ac (200 ppm), significant larvicidal activity was shown against the fourth instars of Ae. aegypti (96%), An. stephensi (93%), and Cx. quinquefasciatus (92%) respectively. The percentages of oviposition deterrence index (ODI) of all three mosquito vectors are maximum at the highest sub-lethal dosage of Pe-Ac (75 ppm) and minimum at the control dosage. The sub-lethal dosage blocked the activity of carboxylesterase activity and upregulated the detoxifying enzyme activity in a dose-dependent way. The adulticidal activity of Pe-Ac showed that the maximum adult mortality rate (100%) was recorded at the prominent dosage of Pe-Ac 600 ppm against the vectors of all three mosquitos at the maximum adulticidal time of 30 min. Histopathological investigation of fourth instar larvae of all three mosquitos treated with a sub-lethal dosage of Pe-Ac showed that the midgut cells (epithelium, lumen, and peritrophic matrix) are ruptured completely whereas they appear to be normal in control larvae. The non-toxicity evaluation of Pe-Ac compared with the chemical toxin Temephos in aquatic predator Toxorhynchites splendens revealed that the plant extracts are harmless even at the prominent dosage (1000 ppm) as compared to Temephos (1 and 2 ppm) and displayed a higher mortality rate against the mosquito predators. Thus the safety index recommends that the Pe-Ac is more explicit to targets and a suitable auxiliary to chemical pesticides.

Synthesis, characterization, X-ray structure and in vitro antifungal activity of triphenyltin complexes based on pyrazole dicarboxylic acid derivatives

A series of new ditriphenyltin(IV) dicarboxylate complexes of general formula (Ph3SnOOC-Pz)(2)R with Pz: pyrazole and R: alkyl or ether, have been synthesized from bipyrazoledicarboxylic acid and hydroxytripheyltin. These complexes, noted C1 C7, have been characterized by IR, H-1 and C-13 NMR spectroscopies. The molecular structures of C3 : 1,3 Bis[(5-methyl-2-H-3-triphenyltincarboxylate pyrazol)]propane and C7: Bis[( 2 methyl-2-H-3-triphenyltincarboxylate pyrazol)ethyl]oxide have been confirmed by single crystal X-ray diffraction. Both compounds crystallize in the monoclinic symmetry: C3 in P2(1) space group with a = 15.915(1) angstrom, b = 10.0791(8) angstrom, c = 13.823(1) angstrom, alpha = 90 degrees, beta = 100.459(3)degrees, gamma = 90 degrees and C7 in P21/n space group, with a = 15.0951(7) angstrom, b = 8.9847(3) angstrom, c = 34.244(1) angstrom, alpha = 90 degrees, beta = 101.421(2)degrees, gamma = 90 degrees. The two cristallographically independent Sn1 and Sn2 atoms are tetra coordinated within distorted tetrahedral environments, very similar in the two compounds. The antifungal activity of these organotin complexes and their corresponding bipyrazoledicarboxylic acid (ligands) has been evaluated against the pathogenic Fusarium oxysporum f. sp. albedinis. This activity greatly depends on the nature of ligands and on the dose used. The presence of triphenyltin moiety improves considerably the antifungal activity becoming close to that of the benomyl (fungicide). (C) 2020 Elsevier B.V. All rights reserved.

The formation of quasi-regular polymeric network of cross-linked sulfobutyl ether derivative of beta-cyclodextrin synthesized with moxifloxacin as a template

Sulfobutyl ether derivative of beta-cyclodextrin, cross-linked in the presence of antibacterial drug moxifloxacin, forms polymeric nanoparticles (50-150 nm in diameter), with highly efficient (up to 85%) encapsulation of the drug. Cyclodextrins (CyDs) have been known for their ability to accommodate a wide range of organic molecules in their inner cavity, leading to guest-host inclusion complexes. Here, we show that in the case of highly cross-linked complex a substantial part of moxifloxacin molecules can be captured by the polymer’s network (i.e. encapsulated in the growing 3D structure) rather than absorbed by the CyD’s inner cavity. This is accompanied by dramatic changes in moxifloxacin’s release kinetics profile: depending on pH, 30-100% of the drug is released from the polymer network within a week. Whereas in the case of moxifloxacin absorption on pre-synthesized CyD polymer matrix, 50% release normally occurs within hours. In vitro studies on Escherichia coli demonstrate that the moxifloxacin in highly cross-linked nanoparticle can preserve over 50% of antibacterial activity for at least 7 days, whereas the same amount of free moxifloxacin, as well as its guest-host complex with CyD, is inactive at this time point. The nanoparticles’ ability to adhere to the bacterial cell wall may contribute to the higher activity of the smaller amount of the drug, emphasizing the potential relevance of this approach for the development of new pharmaceutical formulations.

Model validation of a packed bed LTA membrane reactor for the direct synthesis of DME from CO/CO2

A model for simulating the direct synthesis of dimethyl ether (DME) in a packed bed membrane reactor (PBMR) has been validated, using a LTA zeolite hydrophilic membrane in a lab-scale reaction equipment. In the model, membrane permeability data and the kinetic model corresponding to a CuO-ZnO-ZrO2/SAPO-11 catalyst have been used. Experimental runs have been carried out under the following conditions: 275-325 degrees C; 20-40 bar; space time, 10 g h (mol(C))(-1); CO2/COx ratio, 0, 0.5 and 1; H-2/COx ratio, 3. The model is suitable for predicting the molar fractions of the compounds of the reaction medium (H-2, CO, CO2, H2O, DME, methanol and hydrocarbons) in the reaction and permeate sections of the PBMR, and their evolution with time on stream. DME yield, CO and CO2 conversions are greater in the PBMR than without using the membrane, due to the displacement of the thermodynamic equilibrium by the partial separation of H2O from the reaction medium. For H-2 + CO feeds, the maximum DME yield is 68% at 325 degrees C and 40 bar with a space time value of 10 g h (mol(C))(-1). Otherwise, feeding H-2 + CO2, CO2 conversion reaches 17%, with a DME yield over 5%.
