Synthesis of an Anthracene-Based Macrocyclic Diphosphine Ligand

The synthesis and coordination chemistry of cis-macrocyclic diphosphine (PhPA)(2) (A = C14H10 or anthracene), which features rigid, sterically encumbering groups in its macrocyclic backbone, is reported. Treatment of [EtOP(2)A(2)]AlCl4, obtained in 63% yield from dibenzo-7-phosphanorbornadiene EtOPA and aluminum(III) chloride, with 2 equiv of phenylmagnesium chloride gives (PhPA)(2) in 59% yield. The purple, pseudo-square-planar nickel dichloride complex [(PhPA)(2)]NiCl2 was obtained in 89% yield upon combination of (PhPA)(2) with (DME)NiCl2 in dichloromethane. By virtue of the ligand backbone, [(PhPA)(2)]-NiCl2 exhibits a large percent buried volume of 61.4%, greater than that of other common chelating diphosphines, and the steric bulk is extended into the axial positions of the square-planar complex, as revealed by a single-crystal X-ray diffraction study. Treatment of this nickel dichloride complex with K[B(C6F3)(4)] provided a red dimeric, cationic nickel chloride complex. This dimer was isolated in 43% yield and characterized in a single-crystal X-ray diffraction study.

Aqueous solutions of binary ionic liquids: insight into structure, dynamics, and interface properties by molecular dynamics simulations and DFT methods

The behavior of aqueous solutions of mixtures of ionic liquids (ILs) is of special interest because of their amphiphilic character, from both a fundamental and application viewpoint. In this work, we conducted molecular dynamics (MD) simulations and density functional theory (DFT) calculations to understand the effect of water on the intermolecular interactions in three IL binary mixtures [C(4)mim]/[Cl]/[BF4], [C(4)mim]/[Cl]/[PF6] and [C(4)mim]/[BF4]/[PF6] containing the well-characterized cation, 1-n-butyl-3-methylimidazolium [C(4)mim](+) and the anions chloride [Cl](-), tetrafluoroborate [BF4](-), and hexafluorophosphate [PF6](-). The perturbation of the structures in the binary IL mixture by water molecules was analyzed in the bulk and at the liquid/vacuum interface using distribution functions, hydrogen-bond statistics, and density profiles. Interactions between anions and cations change drastically when the IL mixtures are dissolved in water. In particular, anion-water interactions are stronger than anion-cation interactions. H-Bonds are the dominant interactions. They are prevalently electrostatic and strong for the two [Cl]-containing systems in both the water-free and the water-containing systems. The very hydrophobic [C(4)mim]/[BF4]/[PF6] system gains stability from dispersive interactions and consequently segregates water markedly when admixed. The most probable orientations of IL cations in the bulk and at the vicinity of the interface were examined using bivariate distribution calculations and show [PF6](-) segregating to the surface in keeping with its highly hydrophobic nature. DFT calculated structures, energies, dipole moments, global hardness and solvation energies using model ion pairs [C(4)mim][X] or complexes [C(4)mim](2)[X][Y], with [X/Y](-) = [Cl](-), [BF4](-), or [PF6](-) are completely consistent with the findings for the bulk.

Metabolite Fingerprinting of Kersting’s Groundnut [Macrotyloma geocarpum (Harms) Marechal & Baudet] Seeds Using UPLC-qTOF-MS Reveals the Nutraceutical and Antioxidant Potentials of the Orphan Legume

The identification and subsequent quantification of phenolic compounds in plants is the first step toward harnessing their associated nutritional and health benefits. Due to their diverse phenolic compound compositions, grain legumes are known for their high nutritional and health values. The aim of this study was to assess the inter-variations in chemical composition, phytochemical content, and antioxidant capacity of seed extracts from eight Kersting’s groundnut [Macrotyloma geocarpum (Harms) Marechal & Baudet] landraces. The chemical profiles were evaluated using UPLC-qTOF-MS. Total phenolics and flavonoids content were determined by the Folin-Ciocalteu and aluminum chloride methods, respectively. The antioxidant capacities in the forms of DPPH and ABTS were evaluated using spectrophotometric methods. Principal component analysis was used to define similarities/differences between the landraces. Based on untargeted metabolomics analysis, 57 metabolites were identified, with phenolics, triterpenes, fatty acids, and sphingolipids being the most predominant. The results showed that the black seeded KG1 (Puffeun) had the highest total phenolic (9.44 mg GAE/g) and flavonoid (3.01 mg QE/g) contents, as well as antioxidant capacity (9.17 mu g/mL and 18.44 mu g/mL based on DDPH and ABTS assays, respectively). The concentrations of ferulic acid hexoside, procyanidin B2, eryodictyiol-7-rutinoside and quercetin pentoside ranged from 51.78-441.31, 1.86-18.25, 3.26-13.95 to 5.44-63.85 mu g/mg, respectively. This study presents a useful report on the phytochemical characterization of Kersting’s groundnuts and shows that the grains can be used as a source of nutraceuticals for human consumption.

Antimicrobial properties of diethylamine NONOate, a nitric oxide donor, against Escherichia coli: a pilot study

The emergence of SARS-CoV-2, the causative agent of COVID-19, highlights the increasing need for new and effective antiviral and antimicrobial agents. The FDA has recently banned several active ingredients used in hand sanitizers, including triclosan and benzethonium chloride. Nitric oxide (NO) is involved in the innate immune response and is a major component of macrophage-mediated attack on foreign viruses and bacteria. The specific aim of this study was to assess the antibacterial effects of 2-(N,N-diethylamino)-diazenolate-2-oxide (DEA-NONOate) against Escherichia coli (E. coli). A bacterial growth assay was compared to an adenosine triphosphate (ATP) activity assay at various time points to assess effects of DEA-NONOate on E. coli growth. A UV/Vis spectrophotometer was used to determine concentration of E. coli by measuring optical density (OD) at 630 nm. A luminescent assay was used to measure ATP activity correlating to viable cells. DEA-NONOate at a concentration of 65 mM was able to inhibit the growth of E. coli with the same efficacy as 1 mu g ml(-1) concentration of ciprofloxacin. Both the OD and ATP assays demonstrated a 99.9% reduction in E. coli. Both a 1 mu g ml(-1) concentration of ciprofloxacin and a 65 mM concentration of DEA-NONOate achieved 99.9% inhibition of E. coli, verified using both optical density measurement of bacterial cultures in 96 well plates and a luminescent ATP activity assay. The bactericidal effects of DEA-NONOate against E. coli is proof-of-concept to pursue evaluation of nitric oxide-based formulations as antimicrobial and antiviral agents as hand sanitizers.

Visible-light-induced activation of peroxymonosulfate by TiO2 nano-tubes arrays for enhanced degradation of bisphenol A

TiO2 photocatalysis and peroxymonosulfate (PMS) oxidation can exhibit a good performance in ultraviolet light but a less activity in visible light (VL). Herein, the TiO2 nano-tubes arrays (TiO2NTAs) and PMS were combined to degrade bisphenol A (BPA) under VL irradiation. Surprisingly, about 94.6% of BPA was removed in TiO2 NTAs/PMS/VL system within 30 min, which was much higher than that of TiO2 NTAs/VL (20.1%) and PMS/VL (9.4%) systems. A series of spectroscopic characterizations and photoelectrochemical measurements confirmed the formation of PMS-TiO2 complex with VL response, which can be excited by VL to transfer electrons to the conduction band (CB) of TiO2 for activating PMS. The quenching tests and electron spin resonance (ESR) spectra indicated that SO4 center dot- and center dot OH were responsible for BPA degradation, and then the possible degradation pathways of BPA were proposed. Humic acid (HA) and chloride ions (Cl-) significantly enhanced the BPA degradation, while bicarbonate (HCO3-) and phosphate (H2PO4-) exhibited an inhibition effect. Moreover, TiO2 NTAs/PMS/VL system displayed an enhanced BPA degradation in tap water and drinking water compared with deionized water, and as an immobilization catalyst which fabricated on Ti plate, TiO2 NTAs exhibited excellent stability and separability without complex catalyst separation/recovery processes. We believe this work will provide a new insight of the VL-induced photocatalytic PMS activation in practical water treatment.

Modification of NaCl structure as a sodium reduction strategy in meat products: An overview

Sodium chloride (NaCl) is an indispensable ingredient in meat products, but the consumption of high doses of sodium contained in their formulations may bring about negative health implications. The replacement of NaCl by other salts in meat products has been a technological challenge. Accordingly, this review highlights the importance of NaCl over other sodium and non-sodium salts in the saltiness perception and proposes the use of reduced-size and shapes of NaCl to maximize saltiness perception, while using less NaCl dosages in meat products. However, the effect of matrix components (water, proteins and fats) on the final salty taste is of special consideration. To counteract the effect of the matrix components, two main routes of incorporation of different NaCl types in meat products are discussed: encapsulation and protection of NaCl by the hydrophobic component of the meat product. Given the limited number of publications using this potential strategy, more studies on the application of these technological strategies are required.

Phase Transition from the Interdigitated to Bilayer Membrane of a Cationic Surfactant Induced by Addition of Hydrophobic Molecules

Although the transition between a bilayer and an interdigitated membrane of a surfactant and lipid has been widely known for long, its mechanism remains unclear. This study reveals the transition mechanism of a cationic surfactant, dioctadecyldimethylammonium chloride (DODAC), through experiments and theoretical calculations. Experimentally, the transition from the interdigitated to bilayer structure in the gel phase of DODAC is found to be induced by adding hydrophobic molecules such as n-alkane and its derivatives. Further addition induces a different transition to another bilayer phase. Our theory, considering the competition of the electrostatic interaction between cationic headgroups and the hydrophobic interaction emerging at the alkyl-chain ends exposed to water, reproduces these two phase transitions. In addition, changes in alkyl-chain packing in the membranes at these transitions are reproduced. The underlying mechanism is that the interdigitated membrane is formed at a small additive content due to electrostatic repulsion. As the energetic disadvantage with respect to the hydrophobic interaction becomes dominant as the content increases, the transition to the bilayer occurs at a specific content. The bilayer-bilayer transition at a higher content is induced by the change in the balance of these interactions. Based on a similar concept, we suggest the mechanism of the additive-induced bilayer-interdigitated transition of phospholipids, i.e., neutrally charged (zwitterionic) surfactants.

Highly sensitive fluorescent probe for selective detection of hypochlorite ions using nitrogen-fluorine co-doped carbon nanodots

Hypochlorite ions (ClO-) are widely used in bleaching agents and disinfectants. However, high concentrations of chloride species are harmful to human health. Therefore, effective methods for the detection of ClOions are required. In this study, using 4-fluorophthalic acid and glycine, nitrogen-fluorine codoped carbon nanodots (N,F-CDs) were synthesized by one-pot hydrothermal synthesis for use as a fluorescent probe for the fluorometric detection of ClOin aqueous media, based on the inhibition of n -> pi* transitions. The excitation and emission peak centers of the N,F-CDs are at 387 and 545 nm, respectively. The N,F-CDs show a fast quenching response (<1 min) for ClO and can be used in a wide pH range (pH 4- 13). Under optimal conditions, the fluorescence intensity decreased with increase in the ClOconcentra tionfrom 0 to 35 mu M, anda low limit of detection (9.6 nM) was achieved. This probe possesses excellent selectivity and high sensitivity and was used to analyze standardized samples of piped water, achieving a satisfactory recovery. Thus, this nitrogen-fluorine co-doped nanodot probe is promising for the detection of pollutants. (C) 2020 Elsevier B.V. All rights reserved.

Low temperature co-pyrolysis of food waste with PVC-derived char: Products distributions, char properties and mechanism of bio-oil upgrading

The main components of municipal solid waste (MSW) include food waste (FW) and polyvinyl chloride (PVC), which present an opportunity to convert energy or value-added products through low temperature synergetic pyrolysis. In this study, the characteristics of char and bio-oil derived from MSW, FW and PVC feedstocks via pyrolysis at relatively low temperatures (200-300 degrees C) for 60 min were investigated. The results revealed that the transformation of PVC to HCl gas production started at a temperature of > 200 degrees C. The oxygenated carbon groups on the char surface were decomposed at elevated reaction temperatures. The relative molecular mass of bio-oil derived from FW increased when PVC-derived char was used as a catalyst at 250 degrees C. In addition, active functional groups and pore structures were formed through synergistic pyrolysis. This work provides information regarding the possible route underlying the network of char and bio-oil production from the synergistic conversion of FW and PVC-derived char. (C) 2020 Elsevier Ltd.

Castor Epoxy Fatty Acid Alkyl Ester Estolides as Bioplasticizers for Poly(Vinyl Chloride)

Epoxy fatty acid alkyl ester estolides were synthesized from castor oil to be used as biobased plasticizers for poly(vinyl chloride) (PVC) as a safer replacement for phthalate plasticizers. Initially, castor oil was transesterified with methanol or n-butanol to quantitatively yield castor fatty acid alkyl esters. Acetylation of hydroxyl function with acetic anhydride led to the formation of estolide. The unsaturation was epoxidized, resulting in a bifunctional epoxy fatty acid alkyl ester estolide. The bioplasticizers were compounded with PVC and were evaluated for their functionality and compared with commercial phthalate plasticizer diisononyl phthalate (DINP) and nonphthalate 1,2-cyclohexanoic acid diisononyl ester (DINCH). The bioplasticizers showed excellent gelation, efficiency, and compatibility, as well as plastisol viscosity and thermal properties, comparable to or better than the plastisols prepared with commercial controls DINP and DINCH. The volatility of the methyl ester was inferior to the butyl ester. Both compounds showed low water resistance properties. Further evaluation of the butyl ester under tropical conditions of high temperature and humidity confirmed limited compatibility. This indicates that the castor epoxy fatty acid ester estolides would be better suited for applications that do not come in contact with water for prolonged periods, such as flooring, artificial leather, wiring, or wall coverings.
