The present article describes the synthesis of a new magnetic polyacrylonitrile-based Pd catalyst involving polyacrylonitrile modified via 2-aminopyridine as an efficient support to immobilize Pd nanoparticles. The simple reusability, easy separation and high stability of this Pd complex make it an excellent candidate to generate a C-O bond via Ph-X activation which is a really important subject in achieving biologically active compounds. It is worth to note access to good and high yields as well as broad substrate scope have resulted from superior reactivity of this catalyst complex. Furthermore, the structure of the magnetic polyacrylonitrile-based heterogeneous catalyst was characterized by fourier transmission infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM), X-ray diffraction (XRD). Also, its thermal properties were studied by thermogravimetric analysis (TGA). (C) 2020 Elsevier B.V. All rights reserved.

Co-infection of malaria and tuberculosis, although not thoroughly investigated, has been noted. With the increasing prevalence of tuberculosis in the African region, wherein malaria is endemic, it is intuitive to suggest that the probability of co-infection with these diseases is likely to increase. To avoid the issue of drug-drug interactions when managing co-infections, it is imperative to investigate new molecules with dual activities against the causal agents of these diseases. To this effect, a small library of quinolone-thiosemicarbazones was synthesised and evaluated in vitro against Plasmodium falciparum and Mycobacterium tuberculosis, the causal agents of malaria and tuberculosis, respectively. The compounds were also evaluated against HeLa cells for overt cytotoxicity. Most compounds in this series exhibited activities against both organisms, with compound 10, emerging as the hit; with an MIC90 of 2 mu M against H37Rv strain of M. tuberculosis and an IC50 of 1 mu M against the 3D7 strain of P. falciparum. This study highlights quinolone-thiosemicarabazones as a class of compounds that can be exploited further in search of novel, safe agents with potent activities against both the causal agents of malaria and tuberculosis.

Despite considerable achievements in the hydrogenation of aromatic hydrocarbons over the past few years, the ability to hydrogenate arene or heteroarene rings in a highly selective manner in the presence of other reducible sites or without harming the remaining molecular structure has long been a major challenge. Such chemoselectivity and functional group tolerance is highly desirable for enabling direct access to key building blocks of polymers and pharmaceutical agents. For achieving such high selectivity, the development of suitable catalysts is of central importance. Herein, we report a convenient method for the scalable preparation of ruthenium oxide (RuO2) nanoparticles supported on pine needle char (PNC) by simple impregnation of ruthenium salt on unactivated PNC, a solid byproduct (biochar) obtained in the slow pyrolysis of biomass pine needles. The resulting RuO2-based nanocatalyst (RuO2@PNC) exhibited remarkable activity and high selectivity for the hydrogenation of more than 50 challenging arenes and heteroarenes, including biomass-derived aromatic compounds (e.g., 4-n-propylphenol, furfuryl alcohol, and 2-methyl furan). The synthetic value of this transformation is showcased for the hydrogenation of arene mixture present in petroleum refineries or coal tars as well as biomass-derived oils (bio-oils) with enriched furfural, ether, and phenol derivatives. Under optimized conditions, the performance of this new catalyst was compared with state-of-the-art commercial catalysts such as Ru/C, Pd/C, and Raney nickel and found that RuO2@PNC is more superior and selective. Furthermore, the catalyst is easily recovered and reused up to four cycles.

A hierarchical ZSM-5 zeolite with an adjustable mesoporous size is required for many chemical processes including the biorefining of big biomass compounds. In this research, a simple and high-efficiency hard template method has been successfully developed by adopting carbon nanoparticles obtained from carbonation of polyethylene oxide and urea. The abundant -C-O-C- groups on the surface of carbon nanoparticles provide the high hydrophilicity (from -C-O-C- to -C-O-H) in the alkaline synthetic gel solution, which promotes the synthesis of hierarchical ZSM-5 zeolite and the aluminum condensation in the silica framework to improve the Bronsted acidity. The as-synthesized hierarchical zeolites exhibited two sets of channel systems: micropores (similar to 0.55 nm) are from the MFI framework network, and mesopores (similar to 12.5 and similar to 34.5 nm) result from carbon nanoparticles of 10-40 nm in size, respectively. The hierarchical ZSM-5 with minimized extraframework aluminum species showed catalytic performance with high ethanol conversion (100%) and high stability (lifetime above 30 h) in the ethanol to olefins conversion. Importantly, the diffusion efficiency in ZSM-5 with mesoporous size was remarkably improved, compared to the catalyst with mesoporous size similar to 12.5 nm. As the benzylation of mesitylene with benzyl alcohol, the ZSM-5 (similar to 34.5 nm) sample showed the highest conversion in benzyl alcohol (82.0%) and selectivity in 2-benzyl-1,3,5-trimethylbenzene (74.3%).

In this study, polybrominated diphenyl ethers (PBDEs) levels in soil were studied for a whole year in highly industrialized region of Turkey (Dilovasi) at 23 sampling sites. Sigma 8PBDE concentrations were between 0.15 and 286 mu g kg(-1) and the overall average concentration was 14.45 +/- 25.07 g kg(-1) (average +/- SD). BDE-209 was the most abundant compound. PBDEs concentrations decreased spatially as follows: industrial/urban > urban > suburban > rural. However, there was not any significant seasonal trend except for some industrial/urban sites. In the region, calm weather conditions prevailed during the sampling periods, enhancing the impact of the industrial emissions on nearby soil concentrations by atmospheric deposition without being diluted by winds. All congeners had significant but weak correlations with soil organic matter content indicating the impact of nearby sources rather than soil properties on soil PBDEs concentrations at the sampling sites. Positive matrix factorization method was also used for the apportionment of the PBDEs sources in Dilovasi soil. Industrial activities (i.e., iron-steel production, metallurgical processes, and recycling of plastics), traffic, and residential areas were found to be the primary sources of the measured PBDEs in the soil.

The design of novel materials to use simultaneously in an ocular system for driven therapeutics and wound healing is still challenging. Here, we produced nanocomposites of tungsten disulfide carriers with spherical cobalt ferrite nanoparticles (NPs) as core inside a cubic iron oxide NPs shell (WS2/s-CoFe2O4@c-Fe3O4). Transmission electron microscopy (TEM) confirmed that 10 nm s-CoFe2O4@c-Fe3O4 NPs were attached on the WS2 sheet surfaces. The cytotoxicity of the WS2 sheets and nanocomposites were evaluated on bovine cornea endothelial cells (BCECs) using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay for a duration of three days. The MTT assay results showed low toxicity of the WS2 sheets on BCECs by 67% cell viability at 100 mu g/mL in 24 h, while the nanocomposites show 50% cell viability in the same conditions. The magnetic resonance imaging (MRI) of nanocomposites revealed the excellent T-2-weighted imaging with an r(2) contrast of 108 mM(-1) S-1. The in vitro photothermal therapy based on WS2 sheets and WS2/s-CoFe2O4 @c-Fe3O4 nanocomposites using 808 nm laser showed that the maximum thermal energy dispatched in medium at different applied power densities (1200 mw, 1800, 2200, 2600 mW) was for 0.1 mg/mL of the sample solution. The migration assay of BCECs showed that the wound healing was approximately 20% slower for the cell exposed by nanocomposites compared with the control (no exposed BCECs). We believe that WS2/s-CoFe2O4@c-Fe3O4 nanocomposites have a synergic effect as photothermal therapy agents for eye diseases and could be a target in an ocular system using MRI.

This work deals with the synthesis of zirconium dioxide (ZrO2) nanoparticles (NPs) in different solvents and their structural characterization for better understanding the oxygen donor solvent/zirconium precursor/NPs structure relationships. By selecting solvents over their capacity to produce different crystalline states from alkalinized zirconium alkoxide, spherical nanoparticles with a size of about 1.3-3 nm and a narrow size distribution were elaborated using a nonaqueous solvothermal sol-gel route. Conventional X-ray diffraction (XRD) was used to determine the average structure and crystallite size of the nanoparticles. Well-crystallized and single-phased nanoparticles with average monoclinic and tetragonal structure were obtained with benzaldehyde and benzyl alcohol, respectively, and a much distorted structure was observed for the synthesis in anisole. The atomic pair distribution functions (PDF) of the samples were also analyzed to access the local structure of the nanoparticles. The PDF of the benzaldehyde-prepared sample is consistent with the monoclinic structure. However, the local structure of nanoparticles synthesized with benzyl alcohol does not fully conform to the tetragonal structure observed by XRD, but exhibits monoclinic-like distortions. Lastly, the anisole-prepared nanoparticles present large structural distortions at the medium range and monoclinic local structural features. The restructuring of this last sample was studied by post-treatments in different solvents and leads to the expression of the tetragonal polymorph. Moreover, it seems that the main structural features are obtained in the early stages of the nanoparticles’ formation.

We have designed a functionalized metal-organic framework (MOF) of UiO topology as a support, with an extremely high surface area, adjustable pore sizes and stable crystalline coordination polymeric structure and implanted copper (Cu) nanoparticles thereon. The core three dimensional Zr-derived MOF (UiO-66-NH2) was modified with a biguanidine moiety following a covalent post-functionalization approach. The morphological and physicochemical features of the material were determined using analytical methods such as FT-IR, SEM, TEM, EDX, atomic mapping, XRD and ICP-OES. The SEM and XRD results justified the unaffected morphology of Zr-MOF after structural modifications. The as-synthesized UiO-66-biguanidine/Cu nanocomposite was catalytically explored in the aryl and heteroaryl Buchwald-Hartwig C-N and Ullmann type C-O cross coupling reactions with excellent yields. A library of biaryl amine and biaryl ethers was synthesized over the catalyst under mild and green conditions. Furthermore, the catalyst was isolated by centrifugation and recycled 11 times with no significant copper leaching or change in its activity.

Land application of composted municipal solid waste (C-MSW) can divert waste from landfill but can also be a route of entry into the environment for contaminants. This study presents a preliminary human health and ecological risk assessment for organic contaminants in C-MSW generated in New South Wales, Australia, to identify and prioritise contaminants of concern. Following an initial screening assessment, terrestrial and aquatic risks were assessed by predicted soil and water concentrations, respectively. The assessment ranked contaminants as very high, high, medium or low priority. A qualitative review was then used to identify contaminants of concern, which included polybrominated diphenyl ethers, phthalates, bisphenol A and dibutyltin. Phenol was initially categorised as very high priority but due to its rapid degradation in soil, this is likely to be overly-conservative. The herbicides dicamba and MCPA were categorised as medium priority or higher but due to uncertainties in the data, these categories are also likely to be overly-conservative. A range of contaminants had concentrations below the screening criteria and were therefore considered low risk. Many contaminants were below the limit of reporting in all samples and were therefore not considered to be sufficiently distributed in the material to pose a risk. Some contaminants were detected in the material but could not be assessed as no criteria were available. The information from this study can be used by regulators when managing land application of C-MSW to ensure that the risks to human health and the environment are managed appropriately.
