Evaluation of new chemical and biological nematicides for managing Meloidogyne javanica in tomato production and associated double-crops in Florida

BACKGROUNDTwo field experiments were conducted to determine the efficacy and field performance of three new non-fumigant chemical nematicides (fluensulfone, fluopyram, and fluazaindolizine) and two biological nematicides (Burkholderia rinojensis strain A396 and Purpureocillium lilacinus strain 251) for management of root-knot nematodes (Meloidogyne javanica) on tomato and associated double-crops in Florida. RESULTSIn experiment 1, soil fumigation with metam potassium increased plant growth and reduced root galling on tomato by 77% relative to that of the untreated soil. All non-fumigant chemical nematicides reduced root galling on tomato (47-85% reduction); however, only fluensulfone showed a trend towards yield enhancement. In experiment 2, soil fumigation with chloropicrin increased plant growth and reduced root galling on tomato by 35% relative to that of the untreated soil; however, end-of-season populations of M. javanica in soil were larger than that of the non-fumigated soil. Fluensulfone showed a trend towards reduced root galling and enhanced fruit yield, whereas other non-fumigant nematicides did not. Double-cropped cucumber was 69% more galled when planted into soil previously fumigated with chloropicrin relative to that of untreated soil, and also showed reduced plant vigor and fruit yield. CONCLUSIONFluensulfone shows significant potential to be a component of an integrated pest management strategy for tomato in Florida. (c) 2019 Society of Chemical Industry

In-situ thin coating of silica micro/nano-particles on polymeric films and their anti-fogging application

Polymeric films, e.g., polyethylene (PE), coated with a thin layer of silica micro/nano-particles (SiO2 M/NPs) were prepared using a modified Stober method in the presence of corona treated and non-treated PE films. The obtained films were washed of excess reagents and non-bonded (free) SiO2 M/NPs and dried. Only the corona treated PE films were coated with a thin layer of SiO2 M/NPs while the non-treated films were almost empty of bound SiO2 particles. PE films composed of bound mesoporous silica NPs were similarly prepared with the addition of cetyltrimethylammonium bromide (CTAB) in the polymerization process. The effect of various polymerization parameters, e.g., tetraethylorthosilicate (TEOS) concentration, ammonium hydroxide concentration and the volume ratio [ethanol]/[water], on the diameter and diameter distribution of the free and surface bound particles were elucidated. Characterization of the SiO2 coated films was accomplished by routine methods such as DLS, HRSEM, water contact angle measurements, AFM and FIB. The SiO2 M/NP coatings on the PE films were found to be durable and did not significantly affect the optical properties of the film. Among the different types of SiO2 coated PE films prepared in our lab only those prepared with CTAB were found to be highly suitable for anti-fogging use. This process of SiO2 coating may be used for many other polymeric films, e.g., PET, PP, PMMA, PC, PVC, etc. as well as for various applications such as superhydrophobic, antimicrobial or UV blocking coatings. This can be done by binding long hydrophobic silane compounds (e.g., octadodecyl trichlorosilane), a positively charged silane compound or a UV absorbing silane, respectively, to the bound SiO2 particle surfaces.

Porous nanosheets of carbon-conjugated graphitic carbon nitride for the oxidation of H2S to elemental sulfur

Graphitic carbon nitride (CN) has been reported as an emerging non-metallic catalyst for the oxidation of H2S to elemental sulfur, but its industrial application is hampered by the unsatisfactory catalytic activity. Herein, we report for the first time a facile bottom-up approach to synthesize porous nanosheets of in-plane carbon-conjugated CN (PCNUC) using cetyltrimethylammonium bromide (CTAB) and urea as precursors. The resulted PCNUC catalysts are porous and high in specific surface area because CTAB acts not only as a carbon source for conjugation with CN for the extension of pi-electron system, but also releases gases to function as soft template to create porous CN-based sheets. Thus, the carbon-conjugated CN displays high performance for the catalytic oxidation of H2S to S. Furthermore, the optimized PCNUC catalyst exhibits better durability than the traditional carbon-based and Fe2O3-based catalysts. The results of the present study open up a new avenue for the design of efficient CN-based catalysts for desulfurization reactions. (C) 2019 Published by Elsevier Ltd.

Synthesis of sp(3)-Enriched beta-Fluoro Sulfonyl Chlorides

A three-step approach to the synthesis of sp(3)-enriched beta-fluoro sulfonyl chlorides starting from alkenes is reported. The method was successfully applied to a wide range of acyclic and cyclic substrates, bearing either an exocyclic or an endocyclic double bond. The procedure worked with a wide range of substrates and tolerated a number of functional and protecting groups. Moreover, the target cyclic compounds were obtained as single cis diastereomers on a multigram scale. The title compounds are promising building blocks for drug discovery that can be used to obtain sp(3)-enriched beta-fluoro and alpha,beta-unsaturated sulfonamides.

Ion-association vis a vis hydrophobic effect in novel ionic liquidstetraalkylphosphonium/polyisobutylenesuccinimide-tethered tetraalkylammonium diarylphosphates/thiophosphates: Synthesis and application

A comprehensive study using conventional H-1, P-31 NMR as well as advanced PFGSE-DOSY NMR on structurally unique ionic liquids (ILs) having, in one hand, both phosphorus based counter ions called tetraalkylphosphonium diarylphosphate (PP)/diarylthiophosphate (PTP), and on the other hand polyisobutylenesuccinimide-tethered tetraalkylammonium diarylphosphate (PIBSI-P)/diarylthiophosphate (PIBSI-TP) has been carried out in order to establish their structures and interactions between the counter ions in chloroform solution. It has been noticed that the ion association increases significantly by increasing the cationic alkyl chain length in PP and moderately in PTP owing to stronger hydrophobic interactions. However in polymeric ionic liquids (POILs), PIBSI-P and PIBSI-TP, it is the hydrophobic effect of the long chain PIB backbone which dominates the course, effect of cationic alkyl chain length was not much observed. The 11s were synthesized either from an anion exchange reaction between tetraalkylphosphonium bromides and diaryiphosphate/thiophosphate (former) or from a reaction of same diarylphosphate/thiophosphate with tetraalkylammonium bromide derived from polyisobutylene succinic anhydride (PIBSA) (later). The synthetic procedure is very simple, efficient and high yielding. The developed ILs are found to be effective for application as lubricant additive. (C) 2019 Elsevier B.V. All tights reserved.

Meltblown Polylactic Acid Nanowebs as a Tissue Engineering Scaffold

Polylactic acid (PLA) nanofiber nonwovens have recently come under more vigorous investigation for their use as tissue engineering scaffolds owing to its ability to mimic the physical properties of naturally occurring human extracellular matrix in a variety of host tissues. Currently, the majority of available research on PLA nanowebs has focused on their creation through electrospinning. The goal of this study was to evaluate meltblown nonwoven webs made of nanodiameter PLA fibers for their application as a tissue engineering scaffold. Meltblown PLA fabrics were produced with a variety of different crystallinities, tensile moduli, and pore diameters. One fabric with mechanical properties similar to human dermis was selected as a scaffold to study attachment, proliferation, and migration of human dermal fibroblasts over 1, 3, 7, and 14 days without the use of additional cell adhesion molecules. The 3-(4,5-dimethylthiazol-2-yl)-diphenyltetrazolium bromide assay showed good proliferation from day 1 to 3 (P = 0.026) and up to 7 days of culture (P = 0.005) but without increase from day 7 to 14. Electron microscopy demonstrated adequate cellular attachment and surface migration at 1, 3, 7, and 14 days. Finally, confocal microscopy was used to investigate cellular penetration into the scaffolds. The investigation found that cells were able to penetrate fully through the thickness of the scaffold. The successes of this initial experiment are promising and confirm that meltblown nanofiber nonwovens are a viable avenue for tissue engineering scaffolds. Hopefully, these conclusions will open the door for others to pursue research in this exciting field.

Photocatalytic decarboxylative [2+2+1] annulation of 1,6-enynes with N-hydroxyphthalimide esters for the synthesis of indene-containing polycyclic compounds

An efficient photoredox-mediated [2 + 2 + 1] cascade annulation of 1,6-enynes with N-hydroxyphthalimide esters was reported for the synthesis of a series of indene-containing polycyclic frameworks through a sequence of radical addition, 5-exo-dig cyclization, 1,n-H shift and 5-endo-trig cyclization. This protocol exhibits excellent functional group tolerance for establishing spiro and non-spiro polycyclic architectures under mild conditions. Moreover, this transformation could also be achieved smoothly via a simple phosphine/iodide-based photoredox system.

Dynamic Refolding of Ion-Pair Catalysts in Response to Different Anions

Four distinct folding patterns are identified in two foldamer-type urea-thiourea catalysts bearing a basic dimethylamino unit by a combination of X-ray crystallography, solution NMR studies, and computational studies (DFT). These patterns are characterized by different intramolecular hydrogen bonding schemes that arise largely from different thiourea conformers. The free base forms of the catalysts are characterized by folds where the intramolecular hydrogen bonds between the urea and the thiourea units remain intact. In contrast, the catalytically relevant salt forms of the catalyst, where the catalyst forms an ion pair with the substrate or substrate analogues, appear in two entirely different folding patterns. With larger anions that mimic the dialkyl malonate substrates, the catalysts maintain their native fold both in the solid state and in solution, but with smaller halide anions (fluoride, chloride, and bromide), the catalysts fold around the halide anion (anion receptor fold), and the intramolecular hydrogen bonds are disrupted. Titration of catalyst hexafluoroacetylacetonate salt with tetra-n-butylammonium chloride results in dynamic refolding of the catalyst from the native fold to the anion receptor fold.

Structural and electrochemical studies of bromide derived ionic liquid-based gel polymer electrolyte for energy storage application

In the present studies, poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), ionic liquid {1-Ethyl-3methylimidazolium bromide} (EMIM)(Br), and magnesium perchlorate Mg(ClO4)(2) as salt were used to synthesize free standing electrolyte films by using solution cast technique. The prepared electrolyte films were investigated by using various structural and electrochemical techniques like scanning electron microscopy (SEM), X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) as well as ionic and temperature dependence studies. It has been observed that addition of ionic liquid significantly increases the properties like ionic conductivity, thermal stability, transparency etc. The maximum room temperature ionic conductivity for the optimized system was found to be of the order of 2.05 x 10-2 S cm-1 which is suitable for device fabrication point of view. The optimized electrolyte films are suitable for supercapacitor application.
