Organophosphate esters (OPEs) are commonly used as flame retardants (FRs) and plasticizers. The usage of OPEs has increased recently due to the ban of several brominated flame retardants, but information on levels in the environment, including the indoor environment is still limited. We investigated the occurrence and distribution of 12 OPEs in urban house dust from Vancouver, Canada; Istanbul, Turkey; and Cairo, Egypt. The medianSOPE concentration was 41.4 mu g/g in the Vancouver samples while median levels in Istanbul and Cairo were significantly lower. The median composition profiles of OPEs in Vancouver and Cairo were dominated by tris (2-butoxyethyl) phosphate (TBOEP), accounting for 56 and 92% of total OPEs respectively while it showed a detection frequency of only 14% in Istanbul. Tris (2-chloropropyl) phosphate (TCPP) was the most abundant chlorinated OPE representing 20 and 36% of the total OPEs in Vancouver and Istanbul respectively, but was below the detection limit in the Cairo dust samples. Consistent with other studies, SOPE concentrations were similar to 1 to 2 orders of magnitude higher than PBDEs and currently used flame retardants in the same dust samples. The mean estimated daily intakes (EDI) of SOPE from dust were 115, 38 and 9 ng/kg/bw/day in Vancouver, Cairo and Istanbul respectively for toddlers where adults were similar to 10 times lower. The total toddler OPE intake ranged from 115 to 2900, 38 to 845 and from9 to 240 ng/kg bw/day across the three cities. TBOEP had the largest contribution to the EDI in both toddler and adults, where toddler TBOEP exposures via dust represented 4% to 80%, 2% to 44% and 0.1% to 6% of the Reference Doses (RfD) in the mean and high intake scenarios for toddlers in Vancouver, Cairo and Istanbul respectively.

A series of novel aromatic poly(ether ketone amide)s (PEKAs) were synthesized by the heterogeneous palladium-catalyzed carbonylative polycondensation of aromatic diiodides with ether ketone units, aromatic diamines, and carbon monoxide in N,N-dimethylacetamide (DMAc) at 120 degrees C using 6 mol% of a magnetic nanoparticles-supported bidentate phosphine palladium complex (Fe3O4@SiO2-2P-PdCl2) as catalyst and 1,8-diazabicyclo[5,4,0]-7-undecene as base. The PEKAs had inherent viscosities ranging from 0.61 dl g(-1) to 0.75 dl g(-1). All the PEKAs were soluble in strong dipolar organic solvents. These PEKAs showed glass transition temperatures between 178 degrees C and 232 degrees C and 10% weight loss temperatures ranging from 443 degrees C to 496 degrees C in nitrogen. These PEKAs could be cast into transparent, flexible, and strong films from DMAc solutions with tensile strengths of 72.8-82.6 MPa, tensile moduli of 2.19-2.84 GPa, and elongations at break of 5.4-7.5%. Importantly, the heterogeneous palladium catalyst can be conveniently recovered from the reaction mixture by simply applying an external magnet and recycled up to eight times without significant loss of activity.

Highly active natural pandanus-extracted cellulose-supported poly(hydroxamic acid)-Cu(II) complex 4 was synthesized. The surface of pandanus cellulose was modified through graft copolymerization using purified methyl acrylate as a monomer. Then, copolymer methyl acrylate was converted into a bidentate chelating ligand poly(hydroxamic acid) via a Loosen rearrangement in the presence of an aqueous solution of hydroxylamine. Finally, copper species were incorporated into poly(hydroxamic acid) via the adsorption process. Cu(II) complex 4 was fully characterized by Fourier transform infrared (FTIR), field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray (EDX), transmission electron microscopy (TEM), inductively coupled plasma optical emission spectrometry (ICP-OES), thermogravimetric analysis (TGA), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) analyses. The cellulose-supported Cu(II) complex 4 was successfully applied (0.005 mol %) to the Ullmann etherification of aryl, benzyl halides, and phenacyl bromide with a number of aromatic phenols to provide the corresponding ethers with excellent yield [benzyl halide (70-99%); aryl halide (20-90%)]. Cu(II) complex 4 showed high stability and was easily recovered from the reaction mixture. It could be reused up to seven times without loss of its original catalytic activity. Therefore, Cu(II) complex 4 can be commercially utilized for the preparation of various ethers, and this synthetic technique could be a part in the synthesis of natural products and medicinal compounds.

We report herein the possibility to perform the hydrosilylation of carbonyls using actinide complexes as catalysts. While complexes of the uranyl ion [UO2](2+) have been poorly considered in catalysis, we show the potentialities of the Lewis acid [UO2(OTf)(2)] (1) in the catalytic hydrosilylation of a series of aldehydes. [UO2(OTf)(2)] proved to be a very active catalyst affording distinct reduction products depending on the nature of the reductant. With Et3SiH, a number of aliphatic and aromatic aldehydes are reduced into symmetric ethers, while (Pr3SiH)-Pr-i yielded silylated alcohols. Studies of the reaction mechanism led to the isolation of aldehyde/uranyl complexes, [UO2(OTf)(2)(4-Me2N-PhCHO)(3)], [UO2(mu-kappa(2)-OTf)(2)(PhCHO)](n), and [UO2(mu-kappa(2)-OTf(kappa(1)-OTf)(PhCHO)(2)](2), which have been fully characterized by NMR, IR, and single-crystal X-ray diffraction.

Selective catalytic hydrotreatment of lignin-derived phenols and dimeric ethers into alkanes is crucial for utilization of lignin and its fragments. Herein, we developed an efficient catalytic system with well-dispersed metal nanoparticles supported on SBA-15 synergistic with an ionic liquid. The catalytic system could catalyze the hydrodeoxygenation (HDO) of various monomeric and dimeric lignin-derived phenols into the corresponding alkanes under acid free conditions. The synergistic [Bmim]PF6-Ru/SBA-15 (1-butyl-3-methylimidazolium hexafluorophosphate) catalysis exhibited the best HDO activity for ligninderived phenols and dimeric ethers with >99.0% conversion and maximum > 98.0% selectivity of the corresponding alkanes. The yield of cyclohexane from diphenyl ether was 97.7% with 100% conversion under 2 MPa H-2 at 130 degrees C for 6 h. The mechanism investigation confirmed that the Ru/SBA-15 catalyst and the anion of [Bmim] PF6 played crucial roles in the hydrogenation process and deoxidization process, respectively. The catalytic system was reused six times for HDO of diphenyl ether to test its stability.

The Arctic is subject to long-range atmospheric deposition of globally-distilled semi-volatile organic compounds (SVOCs) that bioaccumulate and biomagnify in lipid-rich food webs. In addition, locally contaminated sites may also contribute SVOCs to the arctic environment. Specifically, Alaska has hundreds of formerly used defense (FUD) sites, many of which are co-located with Alaska Native villages in remote parts of the state. The purpose of this study was to investigate the extent of SVOC contamination on Alaska’s St. Lawrence Island through the analysis of sentinel fish, the ninespine stickleback (Pungitius pungitius), collected from Troutman Lake located within the watershed of an FUD site and adjacent to the Yupik community of Gambell. We measured the concentrations of legacy and emerging SVOCs in 303 fish samples (81 composites), including polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), organophosphate esters (OPEs) and their diester metabolites, and per- and poly-fluoroalkyl substances (PFAS). PBDEs and PCBs were the most abundant SVOC groups found in stickleback with Sigma PBDE and Sigma PCB median concentrations of 25.8 and 10.9 ng/g ww, respectively, followed by PFAS (median Sigma PFAS 7.22 ng/g ww). Sigma OPE and Sigma OPE metabolite concentrations were lower with median concentrations of 4.97 and 1.18 ng/g ww, respectively. Chemical patterns and distributions based on correlations and comparison with SVOC concentrations in stickleback from other parts of the island suggest strong local sources of PCBs, PBDEs, and PFAS on St. Lawrence Island.

Lignin valorization is significantly influenced by the degrees of lignin condensation measured by the amount of cleaved beta-O-4 ether linkages and interunit C-C linkages formed during biomass fractionation. To minimize the cleavage of aryl ether and formation of C-C linkages, a p-toluenesulfonic acid (p-TsOH)/choline chloride (ChCl) solvent system with hydrotropic properties was evaluated. The ChC1 was chosen to control the H+ concentration of the p-TsOH/ChCl solvent system. Compared with p-TsOH/H2O, the degradation of beta-O-4 was kept in a similar rate during p-TsOH/ChCl fractionation; however, the formation of C-C linkage was slower. Under 75/25 p-TsOH/ChCl mass ratio at 80 degrees C for 20 min, 76.6 % of miscanthus lignin, with beta-O-4 content of 30.9 %, and 88.9 % of wheat straw lignin, with beta-O-4 content of 33.6 %, can be dissolved. In addition, the low polar and layered structure of hydrotropic p-TsOH/ChCl system has a strong ability to dissolve lignin, which resulted in lignin with larger particle size and lower surface charge. The results also indicated that lignin from p-TsOH/ChCl solvent system has great potential for lignin depolymerization to aromatics for valorization.

The combination of materials with different magnetic properties at the nanoscale can lead to phenomena such as exchange bias via coupling effects, which shows huge potential for applications, e.g., in storage media or magnetic sensors. Whilst such structures so far are obtained via complex processes of alternating deposition from the gas phase hampering their application, their preparation from nanoparticle dispersions would not only be simplified but also enable a broad variety of possible material combinations and structures. Thereby, the processing of hard magnetic nanoparticles is challenging but can be circumvented by the use of precursor materials with subsequent phase transformation.

Despite the introduction of restrictive regulations in the USA and the European Union, polybrominated diphenyl ethers (PBDEs) are still found in various types of environmental and biological samples at significant concentration levels. The presence of these persistent organic pollutants in the environment raises important issues because of their negative impact on immunological and neurological systems, and on the hormonal balances in living organisms. From the analytical point of view, the final determination of PBDEs would entail substantial challenges, because it would necessitate conducting the pre-concentration of analytes, or sample clean up. The aim of the present study is to demonstrate the analytical application potential of developed dummy molecularly imprinted polymers as solid-phase extraction sorbents for the selective recognition of low-mass PBDEs. The 4,4′-dihydroxydiphenyl ether was employed as a dummy template of low-mass PBDEs. The developed types of the sorption materials were used in the sample preparation stage of the analytical procedure to determine the PBDE-47 and PBDE-99 levels in selected representatives of environmental samples reference materials of soil and bottom sediments. The recovery values of PBDE-47 and PBDE-99 from the studied solid samples ranged from 60% to 87%, depending on the applied DMIPs type.
