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.

Extractable organochlorine (EOCl) and extractable organobromine (EOBr) in GPC-fractionated extracts from high-trophic-level mammals: Species-specific profiles and contributions of legacy organohalogen contaminants

Previous studies have suggested that unidentified compounds constitute a large proportion of extractable organochlorine (EOCl) and extractable organobromine (EOBr) in the crude extracts without fractionation: however, the proportion of unidentified EOX (X = chlorine, bromine) associated with high-/low-molecular-weight compounds is still unknown. In this study, we applied gel permeation chromatography to fractionate extracts from archived liver samples of high-trophic marine and terrestrial mammals (striped dolphins, cats, and raccoon dogs), for which concentrations of legacy organohalogen contaminants (polychlorinated biphenyls, organochlorine pesticides, and polybrominated diphenyl ethers [PBDEs]) had been previously reported. LOX in high-(>1000 g/mol) and low- (<= 1000 g/mol) molecular-weight fractions (EOX-H and EOX-L) were determined by neutron activation analysis. Comparison of EOCl and EOBr enabled the characterization among species. Despite small differences in the concentrations and molecular-weight profiles of EOCl among species, the contribution of chlorine in identified compounds to EOCI-L varied from 1.5% (cats) to 79% (striped dolphins). Considerable species-specific variations were observed in the concentrations of EOBr: striped dolphins exhibited significantly greater concentrations of both EOBr-H and EOBr-L than cats and/or raccoon dogs. Moreover, the contribution of bromine in PBDEs to EOBr-L was >50% in two cats, while it was <6%in other specimens. This is the first report on EOBr mass balance in cetaceans and on EOX mass balance in terrestrial mammals living dose to humans. These results suggest the need for analysis of unidentified chlorinated compounds in terrestrial mammals and unidentified brominated compounds in marine mammals. (C) 2020 Elsevier B.V.

The effect of carbon structure in chars on Fe migration and its catalytic activity for benzyl phenyl ether decomposition

This study aims to further understand the effect of carbon structure on the physiochemical status of metals and thus its activity during volatile-char interactions. The chars with distinctly different carbon substrates prepared from the pyrolysis of pine sawdust at 400 and 1000 degrees C were impregnated by different Fe contents, which were used as catalysts for benzyl phenyl ether (BPE, a typical lignin dimer) decomposition. The results demonstrated that the conversion of BPE was prominently improved with the iron addition, especially when the char prepared at the high temperature was loaded with 10% and 20% iron. The difference in carbon structure of two original chars have clearly resulted in the co-existence of various FexOy in chars at 400 degrees C and the dominant presence of alpha-Fe2O3 in chars at 1000 degrees C. Together with the Fe-containing active sites, the high orientation of carbon structure in the char from 1000 degrees C has considerably favored the high selectivity of product formation during the catalytic reforming of BPE and its derived volatile components.

The influence of acute water stresses on the biochemical composition of bell pepper (Capsicum annuum L.) berries

BACKGROUND Crops are exposed to recurrent and acute drought stress episodes during their vegetative and reproductive cycles, and these episodes are increasingly frequent due to ongoing climate change. Sweet pepper (Capsicum annuum), alias bell pepper, is one of the most widely cultivated vegetables and is grown in open fields worldwide. Here we assessed the effect of acute water stress, applied to a breeding line of sweet pepper at three stages of plant development: five true-leaves (Stage 1), production of the third flower (Stage 2) and setting of the first fruit (Stage 3), on the production and biochemical composition of its ripe fruits. RESULTS The water stress at Stages 1 and 2 induced a delay in fruit ripening, while at Stage 3 caused a drop in production. The biochemical composition of ripe fruits was assessed by quantifying their content in vitamin C, sugars, organic acids, flavonoids as well as 190 volatile organic compounds, mainly belonging to the chemical classes of hydrocarbons, alcohols, ketones, esters, terpenes, aldehydes and ethers. Our results highlight that, at different stages of plant development, acute water stresses modulate differently the accumulation of bioactive compounds in fruits, which play a key role in setting the redox-status and osmotic adjustment of the plant. This was also the case for volatile compounds since, within each chemical class, different compounds varied their content in ripe fruits. CONCLUSIONS On the whole, our results demonstrate that water stresses potentially affect the organoleptic and sensory qualities of bell pepper fruits depending on when they occur.

Preparation of a three-dimensional modified graphene oxide via RAFT polymerization for reinforcing cement composites

Graphene oxide (GO) nanosheets own a large specific surface area and excellent mechanical properties. GO sheets can be dispersed in water to form nano dispersoid, and are easy to composite with cement-based materials. However, the dispersity of GO in alkaline cement slurry is inferior, which causes severe agglomeration, so that the enhancement effect of GO cannot be fully utilized. In this paper, GO-g-PPOE (GE) and GO-g-PPOE-b-PAA (GEA) were synthesized via RAFT polymerization on GO surface. The growth models of poly(poly(ethylene glycol) methyl ether methacrylate) (PPOE) and poly(poly(ethylene glycol) methyl ether methacrylate) -coacrylic acid) (poly(POE-co-AA)) from GO surface were predicted by TEM and SEM. The result of Zeta potential proved that both GE and GEA effectively improved the dispersity of graphene oxide in cement pore solution. Due to the improvement of dispersity and the adsorption of metal ions in cement paste, GE and GEA promoted cement hydration, thereby reinforcing cement composites.

Effects of Hydrophobic Modifications on the Solution Self-Assembly of P(DMAEMA-co-QDMAEMA)-b-POEGMA Random Diblock Copolymers

In this work, the synthesis and the aqueous solution self-assembly behavior of novel partially hydrophobically modified poly(2-(dimethylamino) ethyl methacrylate)-b-poly(oligo(ethylelene glycol) methyl ether methacrylatetabel) pH and temperature responsive random diblock copolymers (P(DMAEMA-co-Q(6/12)DMAEMA)-b-POEGMA), are reported. The chemical modifications were accomplished via quaternization with 1-iodohexane (Q(6)) and 1-iodododecane (Q(12)) and confirmed by H-1-NMR spectroscopy. The successful synthesis of PDMAEMA-b-POEGMA precursor block copolymers was conducted by RAFT polymerization. The partial chemical modification of the diblocks resulted in the permanent attachment of long alkyl chains on the amine groups of the PDMAEMA block and the presence of tertiary and quaternary amines randomly distributed within the PDMAEMA block. Light scattering techniques confirmed that the increased hydrophobic character results in the formation of nanoaggregates of high mass and tunable pH and temperature response. The characteristics of the aggregates are also affected by the aqueous solution preparation protocol, the nature of the quaternizing agent and the quaternization degree. The incorporation of long alkyl chains allowed the encapsulation of indomethacin within the amphiphilic diblock copolymer aggregates. Nanostructures of increased size were detected due to the encapsulation of indomethacin into the interior of the hydrophobic domains. Drug release studies demonstrated that almost 50% of the encapsulated drug can be released on demand by aid of ultrasonication.

High-temperature oxidation of propanol isomers in the mixtures with N2O at high Ar dilution conditions

This work provides, for the first time, new information regarding the kinetics interaction between N2O and propyl alcohol isomers. To this end, the formation and consumption of atomic oxygen were measured behind the reflected shock waves using Atomic Resonance Absorption Spectroscopy (ARAS) technique for 1-10 ppm n- i- propanol + 10 ppm N2O + Ar mixtures, at 2-3 bar and over a wide temperature range of 1700-3200 K. The Konnov and POLIMI detailed combustion mechanisms were assessed against experimental data and also employed to study the main reactions influencing the oxidation dynamics of fuel mixtures under the investigated conditions. The study highlighted a certain difficulty by the models tested in predicting the formation of atomic oxygen at T < 2000 K. The rate of production and the sensitivity analysis was performed with the attempt to identify the most important reactions involved in the process oxidation for future kinetic model refinements.

Experimental and numerical study of polycyclic aromatic hydrocarbon formation in ethylene laminar co-flow diffusion flames

Recent literature kinetic studies revealed the importance of new mechanisms for polycyclic aromatic hydrocarbon (PAH) and soot inception beyond hydrogen-abstraction-acetylene-addition (HACA) and hydrogen-abstraction-vinylacetylene-addition (HAVA) mechanisms in the combustion of ethylene and other hydrocarbons. Co-flow diffusion flame is a canonical flame used to investigate the interaction between fluid dynamics and PAH chemistry. In this study, supersonic molecular beam sampling technique was utilized for the first time with synchrotron vacuum ultraviolet photoionization mass spectrometry (SVUV-PIMS) to measure laminar co-flow diffusion flame at atmospheric pressure. We report quantitative measurement of precursor radicals as well as critical intermediates and odd carbon number PAH species. A custom-designed computational code, based on OpenFOAM and Cantera, was adopted to simulate laminar co-flow diffusion flames with literature kinetic model. Chemical kinetic analyses show that addition reactions of odd carbon number species provide considerable contribution to PAH formation processes beside HACA and HAVA mechanisms. Reasonable mass growth reactions are postulated for aromatic species with odd carbon numbers, such as ethynyl-indene, fluorene, benzo-indene, which need further investigations. Reactions of resonantly stabilized radicals followed by ring expansion are shown to be critical for both odd and even carbon number aromatics, and are suggested to be included in future PAH models.

Highly efficient and selective removal of anionic dyes from aqueous solution by using a protonated metal-organic framework

Hydrothermal reaction of Zn(NO3)(2)center dot 6H(2)O with a flexible bipyridyl ligand, (pyridin-4-yl)methyl 3-(2-(4-((pyridin-4-yl)methoxy)phenyl)diazenyl)benzoate (L) and 1,3-benzenedicarboxylic acid (1,3-H2BDC) gave rise to a novel metal-organic framework (MOF), {[Zn (1,3-BDC)L]center dot H2O}(n). The as-synthesized MOF has been characterized by Fourier transformed infrared (FT-IR), powder X-ray diffraction, single-crystal X-ray diffraction and scanning electron microscopy (SEM). By introduction of the ligand L containing ester, diazene and ether groups, a large number of oxygen and nitrogen sites that can be readily protonated in acidic conditions were successfully decorated on the surfaces of the predesigned MOF. The asprepared protonated Zn-MOF with abundant positive charges (-N=NH+-, -OH+-, -COOH+-) was applied as an adsorbent to remove anionic dyes from aqueous solutions. Such an adsorbent exhibited ultrahigh uptake capacities for different sized anionic dyes of Amido Black 10 B (AB, 2402.82 mg g(-1)), Methyl Orange (MO, 744.02 mg g(-1)), Orange II (OII, 522.83 mg g(-1)) and Direct Red 80 (DR, 1496.34 mg g(-1)). The anionic dyes uptakes of the adsorbent are obviously higher than that of most reported adsorbents. Moreover, the adsorbent showed excellent selectivity in the adsorption of anionic dyes. The adsorption process followed the pseudo-second-order kinetics. The equilibrium adsorption isotherm data were well fitted by Langmuir and Sips models. FT-IR, zeta potential analysis and SEM investigation revealed that the interactions between the protonated Zn-MOF and the anionic dyes are mainly dominated by electrostatic interaction and surface adsorption.

Risks of organic UV filters: a review of environmental and human health concern studies

Organic UV filters are compounds that absorb UV irradiation by their highly conjugated structure. With the developing consciousness over the last century of the skin damage UV radiation can cause, the demand for organic UV filters has risen, for use not only in sunscreens, but also in other personal care products. The massive production and usage of these organic UV filters has resulted in extensive release into the aquatic environment, and thereby making an important group of emerging contaminants. Considering the widespread occurrence of organic UV filters in not only ambient water, but also sediment, soil and even indoor dust, their threats towards the health of living organisms have been a subject of active investigation. In this reviewarticle, we present an overall reviewof existing knowledge on the risks of organic UV filters from the aspects of both environmental and human health impacts. As for the environment, some organic UV filters are proven to bioaccumulate in various kinds of aquatic organisms, and further to have adverse effects on different kinds of animal models. Toxicological studies including in vivo and in vitro studies are important and effectivemeans to ascertain the effects and mechanisms of organic UV filters on both the ecosystemand humans. Subsequent concerns arise that these compounds will affect human health in the long term. This review concludes by suggesting future lines of research based on the remaining knowledge gaps.
