Comprehensive and updated information about polychlorinated biphenyls (PCBs) and brominated flame retardants (BFRs) in surface sediments from Hanoi, the capital city of Vietnam, is rather scarce. In this study, concentrations and profiles of 209 PCBs, 41 polybrominated diphenyl ethers (PBDEs), 2,2 ‘,4,4 ‘,5,5 ‘-hexabromobiphenyl (BB-153), hexabromocyclododecane (HBCD), pentabromoethylbenzene (PBEB), 1,2-bis(2,4,6tribromophenoxy)ethane (BTBPE), and decabromodiphenyl ethane (DBDPE) were determined in sediment samples collected from the Red River and some inner-city rivers of Hanoi. Concentrations (ng/g dry weight, median and range) of pollutants decreased in the order: DBDPE (28; not detected ND – 59) approximate to PCBs (27; 1.7-50) > PBDEs (23; 0.20-61) > HBCD (1.2; ND – 5.2) > BTBPE (0.46; ND – 3.6) > BB-153 (0.004; ND – 0.014) > PBEB (ND). Pollutant levels in the inner-city river sediments were about one to two orders of magnitude higher than those measured in the Red River main stream sediments. Tri-to hexa-CBs are major homologs but detailed profiles vary between individual samples, reflecting source and/or seasonal variations. CB-11 and CB-209 were found at higher proportions in sediments than in technical PCB mixtures, suggesting their novel sources from pigments. Deca-BDE and DBDPE are the most predominant BFRs with an increasing trend predicted for DBDPE. A preliminary ecological risk assessment was conducted for these pollutants in sediments. Total PCBs and deca-BDE in a few inner-city river sediments may exhibit adverse effects on benthic organisms, but no serious risk was estimated in general.

COA of Formula: C14H14O. I found the field of Chemistry; Science & Technology – Other Topics; Materials Science very interesting. Saw the article Direct synthesis of hierarchically structured MFI zeolite nanosheet assemblies with tailored activity in benzylation reaction published in 2019, Reprint Addresses Liu, BY (corresponding author), Guangdong Univ Technol, Sch Chem Engn & Light Ind, Guangzhou 510006, Guangdong, Peoples R China.; Chen, HY (corresponding author), Northwest Univ, Sch Chem Engn, Xian 710069, Shaanxi, Peoples R China.. The CAS is 103-50-4. Through research, I have a further understanding and discovery of Benzyl ether.

The MFI zeolites with nanosheet assemblies morphology were prepared by a seed-assisted strategy using specially designed bolaform surfactant [C6H13-N+ (CH3)(2)-C6H12-N+ (CH3)(2)-(CH2)(12)-O-(p-C6H4)(2)-O-(CH2)(12)-N+(CH3)(2)-C6H12-N+(CH3)(2)-C6H13] [Br-](4) (C6-12-diphe) as a structure-directing agent. The MFI zeolite nanosheet assemblies were composed of MFI nanosheets with randomly organized structure, exhibiting a narrow mesopore distribution. By tuning the Si/AI ratios of MFI zeolite nanosheet assemblies from 60 to 10, the morphology of resultant zeolites changed from nanosheet stacks to house-of-cards-like structures, and to nanosponges. In addition, the porosity and Bronsted acid/Lewis acid ratio exhibited a parabola-type dependence on the Si/Al ratios of obtained zeolites, indicating that meso-/microporosity and acidity of MFI nanosheet assemblies can be systematically tailored by changing the constituents of zeolites. Catalytic performance of MFI zeolite nanosheet assemblies was investigated in the benzylation of benzyl alcohol with mesitylene. The results revealed that MFI zeolite nanosheet assemblies exhibited extraordinary catalytic activity compared to conventional ZSM-5 zeolite. The conversion of benzyl alcohol and selectivity (1,3,5-trimethyl-2-benzylbenzene vs dibenzyl ether) of zeolite catalysts were linearly dependent on the 81-misted acid/Lewis acid ratio, and they exhibited a parabola-type dependence on the S-ext/S-BET, indicating that a balance between acidity and porosity of zeolites can be realized to modulate the catalytic properties of MFI zeolite nanosheet assemblies guided by C6-12-diphe.

The stability of a and beta nanoporous-crystalline (NC) forms of Poly(2,6-dimethyl-1,4-phenylene) oxide (PPO), in the presence of guest molecules leading to crystallization in a and beta-form (alpha and beta-guests), is explored. Sorption of liquid guests at 30 degrees C and 60 degrees C is studied both for NC films and NC aerogels. WAXD and FTIR characterizations show that, for all considered conditions, NC alpha-phases after guest sorption/desorption remain unaltered. NC beta-phases, on the contrary, after alpha-guest sorption can be transformed in co-crystalline (CC) alpha-phases that after guest desorption are transformed in NC alpha-phases. All conducted experiments also show that possible planar orientations of NC films (c//or c perpendicular to orientations) remain essentially unaltered, after sorption of all considered guest molecules. The presently discovered beta ->alpha transition constitutes a route to obtain unoriented alpha-form films, which till now were not available by known preparation procedures.

The synthesis of two-dimensional (2D) zeolites has garnered attention due to their superior properties for applications that span catalysis to selective separations. Prior studies of 2D zeolite catalysts demonstrated enhanced mass transport for improved catalyst lifetime and selectivity. Moreover, the significantly higher external surface area of 2D materials allows for reactions of bulky molecules too large to access interior pores. There are relatively few protocols for preparing 2D materials, owing to the difficultly of capping growth in one direction to only a few unit cells. To accomplish this, it is often necessary to employ complex, commercially unavailable organic structure-directing agents (OSDAs) prepared via multistep synthesis. However, a small subset of zeolite structures exist as naturally layered materials where postsynthesis steps can be used to exfoliate samples and produce ultrathin 2D nanosheets. In this study, we selected a common layered zeolite, the MWW framework, to explore methods of preparing 2D nanosheets via one-pot synthesis in the absence of complex organic templates. Using a combination of high-resolution microscopy and spectroscopy, we show that 2D MMW-type layers with an average thickness of 3.5 nm (ca. 1.5 unit cells) can be generated using the surfactant cetyltrimethylammonium (CTA), which operates as a dual OSDA and exfoliating agent to affect Al siting and to eliminate the need for postsynthesis exfoliation, respectively. We tested these 2D catalysts using a model reaction that assesses external (surface) Brmnsted acid sites and observed a marked increase in the conversion relative to three-dimensional MWW (MCM-22) and 2D layers prepared from postsynthesis exfoliation (ITQ-2). Collectively, our findings identify a facile and effective route to directly synthesize 2D MWW-type materials, which may prove to be more broadly applicable to other layered zeolites.

Microtubule targeting agents represent a very active arena in the development of anticancer agents. In particular, compounds binding at the colchicine site in tubulin are being deeply studied, and the structural information recently available on this binding site allows structure-directed design of new ligands. Structural comparison of our recently reported high resolution X-Ray structure of the cyclohexanedione derivative TUB075 bound to tubulin and the tubulin-DAMA-colchicine complex has revealed a conformational change in the alpha T5 loop. By a grid-based computational analysis of the tubulin-DAMA-colchicine binding site, we have identified a new favourable binding area in the colchicine-site that was unexplored by our lead TUB075. Thus, based on a structure-guided design, new cyclohexanedione derivatives have been synthesized and tested for tubulin binding and in cellular assays. As a result, we have identified diphenyl ether derivatives with IC50 values around 10-40 nM against three different tumor cell lines and affinity constants for tubulin similar to that of colchicine around 10(7) M-1. As expected, they halted the cell cycle progression at G2/M phase at concentrations as low as 0.08 mu M. (C) 2019 Elsevier Masson SAS. All rights reserved.

In this paper, the catalytic behaviour of carbonaceous system (Ccs) functionalized with -SO3H groups were studied in the etherification of refined (Gly) and crude glycerol (GlyC), with benzyl alcohol (BA). This Ccs was obtained by a synthetic method with low energetic cost in only 24 h. Its catalytic activity and selectivity were studied varying the catalyst percentage (2.5, 5 and 10 wt.%), the initial reactant molar ratio and temperature (between 80 and 120 degrees C). A very good catalytic performance was achieved (97 % conversion after 360 min of reaction), at 120 degrees C, Gly:BA = 3:1 and 10 wt.% of Ccs. The high activity can be attributed to high acid site density (6.4 mmol H+/g), that also allowed us to working at lower reaction temperature (100 degrees C) and with less catalyst concentration (2.5 wt.%), without observing significant loss in BA conversion. Monoether (ME1) was the major product of the reaction with 72 % selectivity. The material can be reused and still gives a notable conversion of BA (about 43 %) after three successive reuses. Finally, the Ccs was active and selective to the desired products in the etherification of crude glycerol (GlyC) derived of biodiesel industry. An important BA conversion (45 %) was obtained only reducing the water content of GlyC and without carrying out any other purification and/or neutralization treatment.

Name: Diphenyl oxide. The Name is Diphenyl oxide. Through research, I have a further understanding and discovery of 101-84-8.

Background: Persistent organic pollutants (POPs) are linked with insulin resistance and type-2 diabetes (T2D) in the general population. However, their associations with gestational diabetes (GDM) are inconsistent. Objective: We prospectively evaluated the associations of POPs measured in early pregnancy with GDM risk. We also assessed whether pre-pregnancy BMI (ppBMI) and family history of T2D modify this risk. Methods: In NICHD Fetal Growth Study, Singletons, we measured plasma concentration of 76 POPs, including 11 organochlorine pesticides (OCPs), 9 polybrominated diphenylethers (PBDEs), 44 polychlorinated biphenyls (PCBs), and 11 per-and polyfluoroalkyl substances (PFAS) among 2334 healthy non-obese women at 8-13 weeks of gestation. GDM was diagnosed by Carpenter and Coustan criteria. We constructed chemical networks using a weighted-correlation algorithm and examined the associations of individual chemical and chemical networks with GDM using multivariate Poisson regression with robust variance. Results: Higher concentrations of PCBs with six or more chlorine atoms were associated with increased risk of GDM in the overall cohort (risk ratios [RRs] range: 1.08-1.13 per 1-standard deviation [SD] increment) and among women with a family history of T2D (RRs range: 1.08-1.48 per 1-SD increment) or normal ppBMI (RRs range: 1.08-1.22 per 1-SD increment). Similar associations were observed for the chemical network comprised of PCBs with >= 6 chlorine atoms and the summary measure of total PCBs and non-dioxin like PCBs (138, 153, 170, 180). Furthermore, four PFAS congeners-perfluorononanoic acid (PFNA), perfluorooctanoic acid (PFOA), perfluoroheptanoic acid (PFHpA), and perfluorododecanoic acid (PFDoDA)-showed significant positive associations with GDM among women with a family history of T2D (RRs range: 1.22-3.18 per 1-SD increment), whereas BDE47 and BDE153 showed significant positive associations among women without a family history of T2D. Conclusions: Environmentally relevant levels of heavily chlorinated PCBs and some PFAS and PBDEs were positively associated with GDM with suggestive effect modifications by family history of T2D and body adiposity status.

Meso- and microporous ZSM-5 zeolites were synthesized through combination of the tetrapropylammonium hydroxide (TPAOH) and single quaternary ammonium surfactant (Cph-ph-10-6) as dual templates. The structure-directing ability of Cph-ph-10-6 and TPA(+) was investigated by density functional theory (DFT) calculation. By tuning the molar ratios of Cph-ph-10-6/TPAOH from 5/0 to 5/8, the structure-directing effects between Cph-ph-10-6 and TPA(+) could be systematically modulated, resulting in the morphology of the mesoporous ZSM-5 zeolites changed from ultrathin nanosheets, through splint like nanosheets, to condensed packing plates. In addition, the hierarchical ZSM-5 zeolites exhibited a greater catalytic activity in alkylation of mesitylene with benzyl alcohol compared with conventional ZSM-5 zeolite. The fine control of meso- and microporous structures of ZSM-5 zeolites by a simple one-step dual template synthesis approach allows the design of the desired catalysts for a green and sustainable future.

A series of 20 bis(phenolate-ether) ligands, in combination with Zr and Hf, was tested for performance in propene polymerization, focusing on molecular weight, stereoregularity and regioregularity of the resulting polymer. Ligand variation covers length of the aliphatic linker between the ligand halves, as well as steric bulk of the groups ortho to the phenolate oxygen. The linker length has a dramatic effect on MW: two-carbon linkers produce oligomers (M-n < 2.5 kDa) while three- and four-carbon linkers generate much higher MW (M-n typically 50-500 kDa). Stereoselectivity can be tuned using large, flat substituents in the o-phenolate position; tuning of regioselectivity is much harder. Hf catalysts are slower than their Zr analogs and do not work well with MAO/BHT (BHT = 2,6-di-tert-butyl-4-methylphenol); they are generally more selective (MW, stereo and regio). Density functional calculations agree fairly well with observed selectivities, supporting the involvement of a fac/fac coordinated active species. These O4 catalysts are considerably more flexible than e.g. metallocenes, making accurate prediction of PP microstructure a significant challenge. COA of Formula: C12H10O.

Nano ferrites (AFe(2)O(4), A = Zn, Co, Mn, Cu) were supported on the surface of gamma-Al2O3 support by hydrothermal synthesis to prepare a series of novel composite catalysts (AFe(2)O(4)/gamma-Al2O3) for catalytic ozonation for elimination of high concentration toluene at ambient temperature. The characterization results showed that the high-purity nano-AFe(2)O(4) particles were uniformly loaded on mesoporous gamma-Al2O3. Further, it was confirmed that among the several catalysts prepared, the amount of oxygen vacancies (O-vs), Lewis acid sites (LAS), and BrOnsted acid sites (BAS) of the ZnFe2O4/gamma-Al2O3 catalyst were the highest. This meant that the ZnFe2O4/gamma-Al2O3 catalyst had a strong adsorption capacity for toluene and ozone (O-3), and had a strong catalytic activity. When the temperature was 293 K and the space velocity was 1500 h(-1), the mol ratio of O-3 to toluene was 6, the degradation rate of toluene (600 mg m(-3)) can reach an optimum of 99.8%. The results of electron paramagnetic resonance (EPR) and Fourier infrared (FT-IR) proved superoxide radicals and hydroxyl radicals by catalytic ozonation. Moreover, the GC-MS analysis results indicated that the toluene degradation began with the oxidation of methyl groups on the benzene ring, eventually producing CO2 and H2O. After repeated experiments, the toluene degradation rate remained stable, and the residual content of O-3 in each litre of produced gas was less than 1 mg L-1, thereby indicating that the ZnFe2O4/gamma-Al2O3 catalyst had excellent reusability and showed great potential for the treatment of toluene waste gas.
