Bacterial profiles and volatile flavor compounds in commercial Suancai with varying salt concentration from Northeastern China

Suancai, a popular traditional fermented cabbage in northeast China, is commonly prepared by the spontaneous fermentation process at a certain salt concentration. The salt can affect the metabolites by affecting the microorganisms during Suancai fermentation. The bacterial community and volatile flavor compounds in commercial Suancai from different regions of Northeastern China at different salt concentrations were investigated using next-generation sequencing and GC-MS. Firmicutes and Cyanobacteria were the dominant phyla in the commercial Suancai, and Lactobacillus, Pediococcus, and Leuconostoc were the dominant genera. Among them, Lactobacillus and Pediococcus were considered as the biomarkers of the low and high salt Suncai, respectively. Eighty-five volatile flavor compounds were detected, and HS exhibited higher contents of volatile flavor compounds than LS. Based on the results of correlation analysis, Pediococcus were highly correlated with the alcohols and nitriles in Suancai. The contents of alcohols and nitriles significantly increased in the Suancai, fermented by Pediococcus pentosaceus. The co-inoculated fermentation of Lactobacillus plantarum and P. pentosaceus could increase the concentrations of alcohols, esters, aldehydes, hydrocarbons, and nitriles in Suancai. This study provides a perspective for understanding the ecology of Suancai fermentation and facilitating the fermentation with multispecies inoculation fermentation at an appropriate salt concentration.

Fabrication of carboxyl nitrile butadiene rubber composites with high dielectric constant and thermal conductivity using Al2O3@PCPA@GO hybrids

Owing to excellent adhesion and easy process, dopamine has been widely used as an intermediate for adjusting the molecular structure of nanoparticles. However, the high cost of dopamine largely impedes its large-scale applications. Herein, alumina@poly(catechol-polyamine)@graphene oxide (denoted as Al2O3@PCPA@GO) multilayer core-shell hybrids were prepared via poly(catechol-polyamine) (PCPA) modification. The as-prepared hybrids were added into the carboxyl nitrile butadiene rubber (XNBR) latex to produce composites with high thermal conductivity because of the strong interaction between polar groups in Al2O3@PCPA@GO core-shell hybrids and CN groups in XNBR matrix. Finally, the maximum thermal conductivity (0.48 W/mK) was obtained with 30 vol% Al2O3@PCPA@GO/XNBR composite, which was about three times of pure XNBR matrix (0.16 W/mK). Moreover, 30 vol% Al2O3@PCPA@GO composite showed a high dielectric constant (16.84 at 100 Hz) and low dielectric loss tangent (0.45 at 100 Hz). Besides, the 30 vol% Al2O3@PCPA@GO/XNBR composite displayed a high tensile strength of 11.86 MPa, which is an advantage for practical applications. The developed method has a shorter reaction time and lower cost compared with poly(dopamine) coating, suggesting potential applications as thermally conductive materials for electronic equipment.

A Comparison Study on Reinforcement Behaviors of Functional Fillers in Nitrile Rubber Composites

To investigate the reinforcing effects of functional fillers in nitrile rubber (NBR) materials, high-structure carbon black (HS45), coated calcium carbonate (C-CaCO3), silica (200MP), and multi-walled carbon nanotubes (MWCNTs) were used as functional filler, and carbon black (SRF) as a common filler were used for oil-resistant rubber. The curing and mechanical properties of HS45-, 200MP-, and MWCNT-filled NBR compounds were improved compared to those of the SRF-filled NBR compound. The reinforcing effect also increased with a decrease in the particle size of the fillers. The C-CaCO3-filled NBR compound exhibited no reinforcing effect with increasing filler concentration because of their large primary particle size (2 mu m). The reinforcing behavior based on 100% modulus of the functional filler based NBR compounds was compared by using several predictive equation models. The reinforcing behavior of the C-CaCO3-filled NBR compound was in accordance with the Smallwood-Einstein equation whereas the 200MP- and MWCNT-filled NBR compounds fitted well with the modified Guth-Gold (m-Guth-Gold) equation. The SRF- and HS45-filled NBR compounds exhibited reinforcing behavior in accordance with the Guth-Gold and m-Guth-Gold equations, respectively, at a low filler content. However, the values of reinforcement parameter (100M(f)/100M(u)) of the SRF- and HS45-filled NBR compounds were higher than those determined by the predictive equation model at a high filler content. Because the chains of SRF composed of spherical filler particles are similarly changed to rod-like filler particles embedded in a rubber matrix and the reinforcement parameter rapidly increased with a high content of HS45, the higher-structured filler. The reinforcing effectiveness of the functional fillers was numerically evaluated on the basis of the effectiveness index (phi(SRF)/phi(f)) determined by the ratio of the volume fraction of the functional filler (phi(f)) to that of the SRF filler (phi(SRF)) at three unit of reinforcing parameter (100M(f)/100M(u)). On the basis of their effectiveness index, MWCNT-, 200MP-, and HS45-filled compounds showed higher reinforcing effectiveness of 420%, 70%, and 20% than that of SRF-filled compound, respectively whereas C-CaCO3-filled compound exhibited lower reinforcing effectiveness of -50% than that of SRF-filled compound.

Intermolecular cyclotrimerization of haloketoalkynes and internal alkynes: facile access to arenes and phthalides

A highly chemo- and regioselective cyclo(co)trimerization between 3-halopropiolamides and symmetrical internal alkynes is reported. The reaction is catalyzed by CpRuCl(COD) and proceeds under air at ambient temperature in ethanol with no additional precautions. Iodo-, bromo-, and chloropropiolamides, esters, and ketones are viable coupling partners and, in a 2 : 1 stoichiometry relative to internal alkyne, yield fully-substituted arenes in a single step. The highest regioselectivities (96% single isomer) were observed when employing 2 degrees and 3 degrees-halopropiolamides. A mechanistic hypothesis accounting for this selectivity is proposed. Notably, by using 1,4-butynediol as the internal alkyne, in situ lactonization following [2+2+2]-cycloaddition generates therapeutically-relevant phthalide pharmacophores directly.

Nitrile Oxidation at a Ruthenium Complex leading to Intermolecular Imido Group Transfer

The oxidation of an acetonitrile ligand coordinated to ruthenium is explored in deuterated dimethyl sulfoxide by H-1 NMR spectroscopy. When oxidized with an iodosoarene oxygen atom transfer (OAT) reagent, kinetic studies demonstrate that the nitrile ligand does not dissociate before reacting. Instead, OAT to the central nitrile carbon is implicated (nitrile oxidation) and is further supported by the product of the reaction, N-acyldimethylsulfoximine. The N-acyldimethylsulfoximine likely formed by an imido group transfer reaction from ruthenium to the NMR solvent, and the product was synthesized independently to verify its identity in the reaction. This reaction represents the first time that a nitrile oxidation reaction has resulted in intermolecular imido group transfer to a substrate, presumably through a reactive ruthenium(IV)imido intermediate. This suggests that nitrile oxidation is a plausible route into reactive metal-imido intermediates for amination and aziridination reactions.

Quaternized poly(arylene ether benzonitrile) membranes for vanadium redox flow batteries

A series of quaternized poly (arylene ether benzonitrile)s (QAxCN; x = percent quaternization) were synthesized for the vanadium redox flow battery (VRFB) application. The presence of highly polar nitrile groups incorporated in the quaternized polymer chain provides desirable polymer properties (low water uptake, high dimensional stability and low VO(2+ )permeability) without compromising ion conductivity. VRFB single cells using the aforementioned membranes showed excellent performance. The cell using a 15 mu m-thick QA50CN membrane exhibited superior coulombic efficiency (98.2%) and comparable energy efficiency (86.5%) at 40 mA cm(-2) compared to the single cell using Nafion-212 with a coulombic efficiency of 95.5% and an energy efficiency of 86.2%. The cell cycling stability and membrane oxidative stability data confirmed that the QAxCN membranes have the potential to replace Nafion membranes for energy storage in VRFB applications.

Assessing the Effect of Hofmeister Anions on the Hydrogen-Bonding Strength of Water via Nitrile Stretching Frequency Shift

The temperature dependence of the peak frequency (nu(max)) of the C equivalent to N stretching vibrational spectrum of a hydrogen-bonded C equivalent to N species is known to be a qualitative measure of its hydrogen-bonding strength. Herein, we show that within a two-state framework, this dependence can be analyzed in a more quantitative manner to yield the enthalpy and entropy changes (Delta H-HB and Delta S-HB) for the corresponding hydrogen-bonding interactions. Using this method, we examine the effect of ten common anions on the strength of the hydrogen-bond(s) formed between water and the C equivalent to N group of an unnatural amino acid, p-cyanophenylalanine (Phe(CN)). We find that based on the Delta H-HB values, these anions can be arranged in the following order: HPO42- > OAc- > F- > SO42- approximate to Cl- approximate to (H2O) approximate to ClO4- approximate to NO3- > Br- > SCN- approximate to I-, which differs from the corresponding Hofmeister series. Because PheCN has a relatively small size, the finding that anions having very different charge densities (e.g., SO42- and ClO4-) act similarly suggests that this ranking order is likely the result of specific ion effects. Since proteins contain different backbone and side-chain units, our results highlight the need to assess their individual contributions toward the overall Hofmeister effect in order to achieve a microscopic understanding of how ions affect the physical and chemical properties of such macromolecules. In addition, the analytical method described in the present study is applicable for analyzing the spectral evolution of any vibrational spectra composed of two highly overlapping bands.

Magnesium oxide biosynthesized withCamellia sinensisextract as activator in nitrile rubber vulcanization

Green synthesis of metal and metal oxides is an emerging area in the field of technology and provides economic and environmental benefits as an alternative to physical and chemical processes. In this method, non-toxic reagents that are ecologically correct and safe are used. In this work, MgO was synthesized from the aqueous green tea (Camellia sinensis) extract and characterized by X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis and scanning electron microscopy, which revealed the formation of MgO with face-centered cubic crystalline structure of crystallite size of 15.92 nm. Later, the green MgO obtained was used as activator in nitrile rubber compositions, replacing the industrially used ZnO as a vulcanization activator, and also compared to a commercial MgO. The evaluation was performed regarding the rheometric properties, the kinetic of vulcanization and crosslink density formation. The results obtained were promising both for the synthesis and application of MgO produced via the green route in elastomeric NBR compositions.

Dielectric films with good dielectric breakdown strength based on poly (arylene ether nitrile) enhanced by nano boron nitride and graphene oxide via noncovalent interaction

In recent years, boron nitride and graphene have been widely used in various industries due to their special properties. It is known that the introduction of GO into matrix resin can achieve high dielectric constant and low breakdown strength. In this work, a filler of h-BN-GO was designed through a simple one-step ultrasonic blending method without any surface modification, which is based on the pi-pi interaction between graphene and boron nitride because of their similar layered structure. Then, a flexible dielectric film with good dielectric breakdown strength and thermal conductivity was obtained through introducing the h-BN-GO fillers into poly(arylene ether nitrile). The various testing results show that the nanocomposites possess high mechanical properties (tensile strength > 99 MPa) and thermal stability (T-5% > 453 degrees C). Notably, as the h-BN-GO content increases from 0 wt% to 7.5 wt%, the dielectric constant increases from 4.2 to 7.4 at 1 kHz. Most importantly, when the filler content is 7.5 wt%, the breakdown strength of the h-BN-GO/PEN film is 91.6% higher than that of the GO/PEN film with the same load. Therefore, these h-BN-GO/PEN nanocomposite films exhibit potential in applications as flexible dielectric films.
