Polybrominated diphenyl ethers (PBDEs) and polycyclic aromatic hydrocarbons (PAHs) were detected by gas chromatography-mass spectrometry in the sediment core form Poyang Lake. The concentrations of sigma 17 PBDEs and sigma 15 PAHs ranged from 1.13 to 4.64 ng/g, and from 341 to 744 ng/g, respectively. The Rock-Eval test was conducted to obtain organic matter parameters such as total organic carbon (TOC), S2, and hydrogen index (HI). The value of TOC, S2, and HI showed an increasing trend from the bottom to the surface. Source analysis results showed that the source of PAHs was combustion. Moreover, the correlation analysis of PBDEs, PAHs, and annual average temperature with S2 and HI showed that BDE-202, BDE-201, BDE-183, and BDE-154 were negatively correlated with S2 and HI, while BDE-85 and BDE-47 were positively correlated. There was no significant correlations of PAHs with S2 and HI, which is related to the disturbance of sediments. It is interesting that significantly positive correlation of HI with five-year moving averages of the air temperature was demonstrated, demonstrating that the climate warming enhanced the increase of algae in the Poyang Lake.

A semi-batch reactor was used to carry out the pyrolysis of Ageratum conyzoides. The outcome of pyrolysis parameters vis temperature (350-600 degrees C); heating rate (25-100 degrees C min(-1)) and sweeping gas (N-2) flow rate (0.1-0.5 L min(-1)) were observed on the product yield. The fixed particle size of 0.425 mm was maintained throughout the pyrolysis process. The maximum pyrolytic-oil yield of 37.55 mass% was achieved at a temperature of 525 degrees C under a constant heating rate and sweeping gas flow rate of 75 degrees C min(-1) and 0.2 L min(-1). Biomass, biochar, pyrolytic-oil and pyrolysis-gas were characterized through CHNS and O, FT-IR, TG and DTG, SEM-EDX, BET, XRD, H-1-NMR and GC-MS analysers. The A. conyzoides pyrolytic-oil and biochar has an empirical formula of CH1.32O0.82 and CH0.82O0.44 and a high heating value of 17.79 MJ kg(-1) and 22.93 MJ kg(-1). Presence of lower and higher hydrocarbon compounds in pyrolytic-oil makes it a suitable feedstock for the production of various chemicals. High alkalinity and carbonaceous nature of biochar make it suitable for the modification of soil or can be utilized as a solid fuel. The pyrolysis-gas has a gross calorific value of 5.32 MJ m(-3) and can be utilized as an alternative gaseous energy source.

To achieve high photovoltaic performance of bulk hetero-junction organic solar cells (OSCs), a range of critical factors including absorption profiles, energy level alignment, charge carrier mobility and miscibility of donor and acceptor materials should be carefully considered. For electron-donating materials, the deep highest occupied molecular orbital (HOMO) energy level that is beneficial for high open-circuit voltage is much appreciated. However, a new issue in charge transfer emerges when matching such a donor with an acceptor that has a shallower HOMO energy level. More to this point, the chemical strategies used to enhance the absorption coefficient of acceptors may lead to increased molecular crystallinity, and thus result in less controllable phase-separation of photoactive layer. Therefore, to realize balanced photovoltaic parameters, the donor-acceptor combinations should simultaneously address the absorption spectra, energy levels, and film morphologies. Here, we selected two non-fullerene acceptors, namely BTPT-4F and BTPTT-4F, to match with a wide-bandgap polymer donor P2F-EHp consisting of an imide-functionalized benzotriazole moiety, as these materials presented complementary absorption and well-matched energy levels. By delicately optimizing the blend film morphology, we demonstrated an unprecedented power conversion efficiency of over 16% for the device based on P2F-EHp:BTPTT-4F, suggesting the great promise of materials matching toward high-performance OSCs.

Pearl-farming leads to significant plastic pollution in French Polynesia (FP) as the end of life of most farming gear is currently poorly managed. Plastic debris released into the aquatic environment accumulates, with potentially detrimental effects on the lagoon ecosystem and pearl oyster Pinctada margaritifera, a species of ecological, commercial and social value. Here, we tested the effects of leachates from new (N) and aged (A) plastic pearl-farming gear (spat collector and synthetic rope) obtained after 24 h and 120 h incubation, on the embryo-larval development of the pearl oyster using an in-vitro assay. Embryos were exposed for 24 h and 48 h to a negative control (0) and the leachate from 0.1, 1, 10 and 100 g of plastic. L-1. After 24 h exposure to leachate at 100 g.L-1, effects were observed on embryo development (-38% to -60% of formed larvae) and mortality (+72% to +82%). Chemical analyses of plastic gear indicated the presence of 26 compounds, consisting of organic contaminants (PAHs) and additives (mainly phthalates). Screening of leachates demonstrated that these compounds leach into the surrounding seawater with an additional detection of pesticides. Higher levels of phthalates were measured in leachates obtained from new (6.7-9.1 mg.L-1) than from aged (0.4-0.5 mg.L-1) plastics, which could be part of the explanation of the clear difference in toxicity observed after 48 h exposure at lower concentrations (0.1-10 g.L-1), associated with mortality ranging from 26 to 86% and 17-28%, respectively. Overall, this study suggests that plastic gear used in the pearl-farming industry releases significant amounts of hazardous chemicals over their lifetime, which may affect pearl oyster development that call for in-situ exploration.

The Name is Benzyl ether. Through research, I have a further understanding and discovery of 103-50-4.

A highly efficient Ni/N-C catalyst was synthesized by facile pyrolysis of a Ni-containing metal-organic framework (Ni-MOF), and its catalytic hydrogenolysis performance towards C-O bonds in lignin was evaluated in detail using diphenyl ether (DPE) as a model compound. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analyses show that the flower-like nanosheets of the Ni-MOF shrink, forming a loose and ordered spherical structure during pyrolysis. Under the optimal conditions, DPE was completely converted and the selectivity to monomers (benzene, cyclohexanol and cyclohexane) reached 99.1%. During the catalytic hydrogenolysis conversion (CHC) of DPE, the direct cleavage of the C-aromatic-O bond affording benzene and phenol is the major reaction pathway, and a low H2 pressure is crucial to increase the monomer selectivity. Furthermore, Ni/N-C-450 shows high hydrogenolysis activity for other lignin-derived aryl ethers, such as benzyl phenyl ether, dibenzyl ether, dinaphthalene ether, benzyl 2-naphthyl ether and 3-methoxyphenol.

UV-curable inks, coatings, and adhesives are being increasingly used in food packaging systems. When exposed to UV energy, UV-photoinitiators (PI’s) present in the formulations produce free radicals which catalyze polymerization of monomers and pre-polymers into resins. In addition to photopolymerization, other free radical reactions occur in these systems resulting in the formation of chemically varied photolytic decomposition products, many of which are low molecular weight chemical species with high migration potential. This research conducted model experiments in which 24 commonly used PI’s were exposed to UV-energy at the typical upper limit of commercial UV-printing press conditions. UV-irradiated PI’s were analyzed by gas chromatography-mass spectrometry (GC-MS) and electrospray-mass spectrometry (ESI-MS) in order to identify photolytic decomposition products. Subsequently, migration studies of 258 UV-cure food packaging samples were conducted using GC-MS; PI’s and photolytic decomposition products were found in nearly all samples analyzed. One hundred-thirteen photolytic decomposition products were identified. Eighteen intact PI’s and 21 photolytic decomposition products were observed as migrants from the 258 samples analyzed, and these were evaluated for frequency of occurrence and migratory concentration range. The most commonly observed PI’s were 2-hydroxy-2-methylpropiophenone and benzophenone. The most commonly observed photolytic decomposition products were 2,4,6-trimethylbenzaldehyde and 1-phenyl-2-butanone. This compilation of PI photolytic decomposition data and associated migration data will aid industry in identifying and tracing non-intentionally added substances (NIAS) in food packaging materials.

Magnesium-stabilized amorphous calcium carbonate (Mg-ACC), amorphous magnesium calcium silicate hydrate (MCSH), and hydroxyapatite (HAp) are prepared by a precipitation method. By cold-pressing these particles, it is possible to produce porous bulk discs with a narrow pore size distribution. These porous inorganic discs (Mg-ACC, MCSH, and HAp) are investigated as stationary phases to study the chromatographic behavior and adsorption ability of rhodamine B, methylene blue, and ribonuclease. The adsorption affinities of different biomolecules can be easily observed and evaluated through this method. Furthermore, by infiltrating fabricated opaque porous discs with benzyl ether, which has a similar refractive index as the used inorganic particles (Mg-ACC, MCSH, and HAp), their optical properties significantly change and the discs become translucent. Moreover, by infiltrating the MCSH discs with a light-curing polymer, translucent composites with good surface hardness are fabricated. By doping particles with ions such as Ni2+, Co2+ , Fe3+, and Eu3+, the color and UV-visible spectrum of the bulk discs can be adjusted. Typically, by using iron-doped MCSH particles as the inorganic matrix, nanocomposites, which show a steep UV-absorption edge at 400 nm, are fabricated. Our work provides a simple and economical method to evaluate the affinity of biomolecules to inorganic materials and a novel way to fabricate translucent hard composite materials. The fabricated nanocomposite discs show a great UV shielding effect and superior surface hardness compared to polymethyl methacrylate and commercial sunglasses, suggesting their potential as new sunglass materials.
