Boehmite is a cubic orthorhombic structure of aluminum oxide hydroxide, which prepared via addition of sodium hydroxide solution to an aluminum nitrate solution at room temperature. In this work, the surface of boehmite nanoparticles (BNPs) modified by 3-choloropropyltrimtoxysilane (3-CPTMS), then reacted with N,N,N ‘,N ‘-tetraethyldiethylentriamine (TEDETA). Eventually, Cu-I immobilized on modified boehmite (Cu-I-TEDETA@BNPs). Structure of this catalyst was characterized using FT-IR, TEM, SEM, EDS, TGA, and AAS techniques. Finally, the catalytic activity of Cu-I-TEDETA@BNPs was studied for the synthesis of ethers and sulfides. All ethers and sulfides were obtained in high yields, which reveals the high activity of described catalyst. This catalyst was reused for several times without significant loss of its catalytic efficiency. Recovered catalyst was characterized by SEM and FT-IR techniques, which shown a good agreement with fresh catalyst. Also, heterogeneity and stability of Cu-I-TEDETA@BNPs confirmed by hot filtration test.

Using thianthrene S-oxide (TTSO) as a transient mediator, para-arylation and alkenylation of mono-substituted arenes have been demonstrated via a para-selective thianthrenation/Pd-catalyzed thio-Suzuki-Miyaura coupling sequence under mild conditions. This reaction features a broad substrate scope, and functional group and heterocycle tolerance. The versatility of this approach was further demonstrated by late-stage functionalization of complex bioactive scaffolds, and direct synthesis of some pharmaceuticals, including Tetriprofen, Ibuprofen, Bifonazole, and LJ570.

Background Prenatal maternal plasma persistent organic pollutant (POP) concentrations have been associated with neonatal outcomes. However, the underlying mechanisms remain unknown. Placental epigenetic mechanisms may be involved, but no prior epigenome-wide studies have investigated the impact of maternal POPs on placental DNA methylation. We studied the association between maternal plasma POP concentration in early pregnancy and epigenome-wide placental DNA methylation among 260 pregnant women from the NICHD Fetal Growth Studies. Results Our analysis focused on POPs with more than 80% plasma concentrations above the limit of quantification, including 3 organochlorine pesticides (hexachlorobenzene, trans-nonachlor,p,p’-dichlorodiphenyldichloroethylene), 1 polybrominated diphenyl ether (PBDE 47), 3 polychlorinated biphenyls (138/158, 153, 180), and 6 poly- and perfluorinated alkyl substances (PFASs) (perfluorodecanoic acid, perfluorohexanesulfonic acid, perfluorononanoic acid, perfluorooctanesulfonic acid, perfluoroundecanoic acid (PFUnDA)). Using 5% false discovery rate, POPs were associated with a total of 214 differentially methylated CpG sites (nominalpvalues ranging from 2.61 x 10(-21)to 2.11 x 10(-7)). Out of the 214 CpG sites, 24 (11%) were significantly correlated with placental expression of 21 genes. Notably, higher PFUnDA was associated with increased methylation at 3 CpG sites (cg13996963, cg12089439, cg18145877) annotated toTUSC3, and increased methylation at those 3 CpG sites was correlated with decreased expression ofTUSC3in the placenta. Increased methylation at cg18145877 (TUSC3) and decreased expression ofTUSC3were correlated with shorter birth length. Out of the 214 CpG sites, methylation at 44 CpG sites was correlated (pvalue < 0.10) with at least one neonatal anthropometry measure (i.e., birth weight, birth length, and head circumference). Seven CpG sites mediated (pvalue < 0.05) the association between PBDE 47 and neonatal anthropometry measures. Genes annotating the top differentially methylated CpG sites were enriched in pathways related to differentiation of embryonic cells (PBDE 47) and in pathways related to brain size and brain morphology (PFASs). Conclusions DNA methylation changes in the placenta were significantly associated with maternal plasma POPs concentration. The findings suggest that placental DNA methylation and gene expression mechanism may be involved in the prenatal toxicity of POPs and their association with neonatal anthropometry measures.

Predicting retention and enthalpy allows for the simulation and optimization of advanced chromatographic techniques including gradient separations, temperature-assisted solute focusing, multidimensional liquid chromatography, and solvent focusing. In this paper we explore the fits of three expressions for retention as a function of mobile phase composition and temperature to retention data of 101 small molecules in reversed phase liquid chromatography. The three retention equations investigated are those by Neue and Kuss (NK) and two different equations by Pappa-Louisi et al., one based on a partition model (PL-P) and one based on an adsorption model (PL-A). More than 25 000 retention factors were determined for 101 small molecules under various mobile phase and temperature conditions. The pure experimental uncertainty is very small, approximately 0.22% uncertainty in retention factors measured on the same day (2.1% when performed on different days). Each of the three equations for ln(k) was fit to the experimental data based on a least-squares approach and the results were analyzed using lack-of-fit residuals. The PL-A model, while complex, gives the best overall fits. In addition to examining the equations’ adequacy for retention, we also examined their use for apparent retention enthalpy. This enthalpy can be predicted by taking the derivative of these expressions with respect to the inverse of absolute temperature. The numerical values of the fitted parameters based on retention data can then be used to predict retention enthalpy. These enthalpy predictions were compared to those obtained from a modified van ‘t Hoff equation that included a quadratic term in inverse temperature. Based on analysis of 1 211 van’t Hoff plots (solute-mobile phase-day combinations), ninety-eight percent showed a significantly better fit when using the modified van ‘t Hoff expression, justifying its use to provide apparent enthalpies as a function of mobile phase composition and temperature. The foregoing apparent enthalpies were compared to the apparent enthalpies predicted by the three models. The PL-A model, which contains a temperature dependent enthalpy, provided the best enthalpy prediction. However, there is virtually no correlation between the overall lack of fit to experimental ln(k) for each model and the corresponding lack of fit of the linear (in 1/T) van ‘t Hoff expression. Thus, the temperature-dependent enthalpy is apparently not the cause of a model’s ability to fit ln(k) as a function of mobile phase composition and temperature. The value in these expressions is their ability to predict chromatograms, allowing for optimization of an advanced chromatographic technique. The two simpler models NK and PL-P, which do not contain a temperature dependent enthalpy, have their merits in modelling retention (NK being the better of the two) and enthalpy (PL-P being the better of the two) if a simpler expression is required for a given application.

A multitude of metrics exist to assign scores to synthetic routes within computer-aided synthesis planning (CASP) tools. A quantitative scoring method is necessary to identify the most promising synthetic approaches to a molecule. However, current CASP tools are limited in their capacity to evaluate reaction selectivity and are unable to fully account for the effect of side products on the purification sequences associated with chemical syntheses. We develop a novel quantitative metric called ExtractionScore for evaluating synthetic routes based on the predicted identities of side products as well as the separability of major and side products by liquid-liquid extraction based on chemical property prediction. By comparing industrially practiced routes to a collection of 200 pharmaceutically relevant compounds with routes suggested by state-of-the-art CASP software, we show that ExtractionScore may improve retrosynthetic recommendations by incorporating information about the formation of side products.

Restrictions of legacy brominated flame retardants, such as polybrominated diphenyl ether (PBDE) and polybrominated biphenyl (PBB), have resulted in increased usage of alternative halogenated flame retardants (AHFRs). Consequently, AHFRs contamination has caused a major concern in the scientific community. However, there is limited information on their presence in marine mussels. In this study, we investigated the occurrence and distribution of polybrominated biphenyls (PBBs), AHFRs and dehalogenated products in green mussels collected from 22 locations in the northern South China Sea (SCS). Our results revealed that Sigma AHFRs were ubiquitous in green mussels with concentrations in the range of 1.08-7.71 ng/g lipid weight (lw). Among target AHFRs, hexabromobenzene (HBB), decabromodiphenyl (DBDPE) and dechlorane plus (DP) were predominant with their mean values of 1.19, 1.00 and 0.82 ng/g lw, respectively. There were negligible stereoisomer enrichments of DP in green mussels based on f(anti) values, indicating a limited bioaccumulation and metabolism of DP in green mussels. In comparison with other locations, concentrations of the AHFRs in green mussels determined here were at moderate levels. Additionally, there were significant linear relationships between some AHFRs (e.g., HBB and PBEB), suggesting their similar commercial applications and sources in the environment. The estimated daily intakes of AHFRs through consumption of green mussels by the local population in South China were 0.05-0.14 ng/kg body weight/day and 0.17-0.44 ng/kg body weight/day based on the mean and 95th concentrations, respectively. To the best of our knowledge, the present study is the first to report AHFRs and dehalogenated products in green mussels.

For materials as BaCo(0.4)Fe(0.4)Zr(0.1)Y(0.1)O(3-delta)with three independent mobile charge carriers, hole, oxygen ion, and proton, a peculiar twofold diffusion and transition from hydration to hydrogenation in proton uptake are investigated by electrical conductivity relaxation method in this work. At 700 degrees C, the water incorporation reaction would happen in the formation of both hydration and hydrogenation. The hydration reaction would happen at the sacrifice of oxygen vacancy, and then, the incorporated proton diffuses from outer layer to the inner bulk. But due to much higher chemical diffusion coefficient of proton than oxygen vacancy, the highly mobile protons are charge compensated by holes, instead of waiting for the less mobile oxygen vacancy, and thus causes the speeding increased hole concentration, i.e., increased conductivity. So in the hydration reaction, the decoupled diffusion of proton and oxygen vacancy would result in a non-monotonic conductivity relaxation curve, i.e., twofold diffusion. After that, the proton uptake reaction would transit to hydrogenation, as total decreased conductivity in a monotonic curve.

This study was carried out to investigate the risks of simultaneous exposure to pesticide residues and bacteria contaminants in locally produced fresh vegetables and vegetables in Tanzania. A total of 613 samples were analyzed for pesticide residues, out of which 250 were also analyzed for bacterial contamination. Overall, 47.5% had pesticide residues, 74.2% exceeded Maximum Residue Levels (MRLs). Organophosphorus (95.2%), organochlorines (24.0%), pyrethroids (17.3%), and carbamates (9.2%) residues dominated. MRL values were mostly exceeded in tomatoes, onions, watermelons, cucumbers, Chinese cabbage, and sweet paper. Tetramethrin (0.0329-1.3733 mg/kg), pirimiphos-methyl (0.0003-1.4093 mg/kg), permethrin (0.0009-2.4537 mg/kg), endosulfan (beta) (0.0008-2.3416 mg/kg), carbaryl (0.0215-1.5068 mg/kg), profenofos (0.0176-2.1377 mg/kg), chlorpyrifos (0.0004-1.2549 mg/kg) and dieldrin (0.0011-0.5271 mg/kg) exceeded MRLs. The prevalence of bacteria contamination was high (63.2%). Enterobacter (55.6%) Pseudomonas aeruginosa (32.4%), E. coli (28.2%), Citrobacter (26.8%), Klebsiella oxytoca (14.8%), and Salmonella (7.7%) were isolated. Furthermore, 46.4% tested positive for both pesticide residues and bacterial contaminants. Vegetables from farms (60.7%) contained more dual contaminants than market-based vegetables (41.8%). This may have resulted from excessive pesticide use and unhygienic handling of fresh fruits and vegetables at production level. Binary logistic regression showed that fresh fruits and vegetables with pesticide residues were 2.231 times more likely to have bacteria contaminants (OR: 2.231; 95% CI: 0.501, 8.802). The contamination levels of pesticide residues and bacterial contaminants could be perceived as a serious problem as most fresh fruits and vegetables recorded values of pesticide residues far above the MRLs with pathogenic bacteria isolated in higher proportions. MRLs was higher in most vegetables consumed raw or semi-cooked such as watermelons, carrots, cucumber, tomatoes, onion and sweet paper. There is an urgent need to develop pesticide monitoring and surveillance systems at farmer level, educating farmers and promoting the use of greener pesticides to mitigate the health effects of pesticides and bacterial contaminants.

Hydrogen evolution reaction (HER), a promising strategy for converting electricity to value-added H-2 fuel, is a key half reaction of the overall water splitting. However, HER is suffering from the sluggish kinetics in alkaline. We here demonstrate a highly efficient catalyst for alkaline HER via surface and interface engineering of RhOOH nanosheets (NSs). The surface structure of RhOOH NSs can be precisely tuned by altering the cyclic voltammogram cycles (CVs) in the activation process, leading to the formation of strongly synergized RhOOH/Rh interface for boosted HER activity in alkaline. The optimized catalyst exhibits a promising alkaline HER performance with overpotential of 18 mV at current density of 10 mA center dot cm(2) and Tafel slope of 19.3 mV center dot dec(-1) in 1 M KOH, which surpasses the commercial Pt/C, Rh NSs/C and RhOOH NSs/C. Detailed experiments and theoretical calculations reveal that the synergy between RhOOH and Rh significantly promotes the H2O adsorption/ dissociation to form Had and the Had desorption to produce H-2.
