A dual functional Janus membrane combining superwettability with electrostatic force for controllable anionic/cationic emulsion separation and in situ surfactant removal

In the oil/water emulsion treatment field, the separation of dispersed tiny oil droplets and the removal of surfactants are both significant in order to obtain purified water. Superwetting materials have proved to be an ideal solution for stabilized emulsion separation. However, most of the previous studies only focus on the separation of oil from water while neglecting the removal of surfactants. With the purpose of realizing in situ emulsion separation and surfactant removal, a dual functional Janus membrane is designed inspired by mussel-inspired chemistry and an EDC/NHS coupling reaction. After modification, abundant amino groups and carboxyl groups are decorated on two sides of the microfiltration membrane substrate, respectively (denoted as the -NH2 side and -COOH side). Combining special wettability with electrostatic interaction, the as-prepared membrane is able to separate stabilized oil-in-water emulsions and remove anionic/cationic surfactants simultaneously. The -NH2 side is used for the treatment of anionic emulsions with the surfactant sodium dodecyl sulfate (SDS), while the -COOH side is used for the treatment of cationic emulsions with the surfactant hexadecyl trimethyl ammonium bromide (CTAB). More importantly, the separation efficiencies are all above 99.5% and the surfactant removal efficiencies are up to 95.7%. To our knowledge, this is the first time to treat both dispersed oil droplets and surfactants using superwetting materials. The excellent recyclability and stability of the Janus material make it a potential candidate for application in the industrial field.

Fe3O4@Au/reduced graphene oxide nanostructures: Combinatorial effects of radiotherapy and photothermal therapy on oral squamous carcinoma KB cell line

Combination therapy including radiotherapy (RT) and photothermal therapy (PTT), as an alternative treatment for cancer treatment, recently has generated substantial interest. Graphene-based nanocarbons and gold content metallic nanoparticles, as one of the most attractive materials with their extraordinary physical and chemical properties, are extremely useful in this regard. We herein reported the effects of combination of cancer therapy including RT (doses of 2 and 4 Gy) and PTT (808 nm laser irradiation, NIR irradiation) as radio-photothermal therapy (RPTT) of KB oral squamous carcinoma cell line in the presence of Fe3O4@Au/reduced graphene oxide (rGO) nanostructures (NSs) at different concentrations. Fe3O4@Au/rGO NSs with different rGO contents have been synthesized by hydrothermal reaction method. They characterized by XRD, FE-SEM, TEM, EDS, FTIR and TGA. Cell viability for cytotoxicity, RT, PTT and RPTT were studied by MTT (3[4,5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide) assay. High photothermal conversion efficiency of Fe3O4@Au/rGO NSs reaches to 61%. The resulting Fe3O4@Au NPs with approximate size of about 10-60 nm covered the rGO nanosheets with 40 wt% rGO at concentration of 20 mu g ml(-1), exhibited satisfactory cytotoxicity. They provided significant cell destruction under RT, PIT and specially RPTT in dose of 4 Gy. Furthermore, they have good biocompatibility on the healthy cells. Our results show that Fe3O4@Au/rGO NSs integrated with radiosensitization, photothermal therapy and their combination promising for nanomedicine and clinical applications.

Direct Z-Scheme Heterojunction of Semicoherent FAPbBr(3)/Bi2WO6 Interface for Photoredox Reaction with Large Driving Force

Metal halide perovskites with direct band gap and strong light absorption are promising materials for harvesting solar energy; however, their relatively narrow band gap limits their redox ability when used as a photocatalyst. Adding a second semiconductor component with the appropriate band structure offsets can generate a Z-scheme photocatalytic system, taking full advantage of the perovskite’s intrinsic properties. In this work, we develop a direct Z-scheme photocatalyst based on formamidinium lead bromide and bismuth tungstate (FAPbBr(3)/Bi2WO6) with strong redox ability for artificial solar-to-chemical energy conversion. With desirable band offsets and strong joint redox potential, the dual photocatalyst is shown to form a semicoherent heterointerface. Ultrafast transient infrared absorption studies employing selective excitation reveal synergetic photocarrier dynamics and demonstrate Z-scheme charge transfer mechanisms. Under simulated solar irradiation, a large driving force photoredox reaction (similar to 2.57 eV) of CO2 reduction coupled with benzyl alcohol oxidation to benzaldehyde is achieved on the Z-scheme FAPbBr(3)/Bi2WO6 photocatalyst, harnessing the full synergetic potential of the combined system.

Nickel-Catalyzed, Regio- and Enantioselective Benzylic Alkenylation of Olefins with Alkenyl Bromide

A NiH-catalyzed migratory hydroalkenylation reaction of olefins with alkenyl bromides has been developed, affording benzylic alkenylation products with high yields and excellent chemoselectivity. The mild conditions of the reaction preclude olefinic products from undergoing further isomerization or subsequent alkenylation. Catalytic enantioselective hydroalkenylation of styrenes was achieved by using a chiral bisoxazoline ligand.

In Vitro Tests of FDM 3D-Printed Diclofenac Sodium-Containing Implants

One of the most promising emerging innovations in personalized medication is based on 3D printing technology. For use as authorized medications, 3D-printed products require different in vitro tests, including dissolution and biocompatibility investigations. Our objective was to manufacture implantable drug delivery systems using fused deposition modeling, and in vitro tests were performed for the assessment of these products. Polylactic acid, antibacterial polylactic acid, polyethylene terephthalate glycol, and poly(methyl methacrylate) filaments were selected, and samples with 16, 19, or 22 mm diameters and 0%, 5%, 10%, or 15% infill percentages were produced. The dissolution test was performed by a USP dissolution apparatus 1. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide dye (MTT)-based prolonged cytotoxicity test was performed on Caco-2 cells to certify the cytocompatibility properties. The implantable drug delivery systems were characterized by thermogravimetric and heatflow assay, contact angle measurement, scanning electron microscopy, microcomputed tomography, and Raman spectroscopy. Based on our results, it can be stated that the samples are considered nontoxic. The dissolution profiles are influenced by the material properties of the polymers, the diameter, and the infill percentage. Our results confirm the potential of fused deposition modeling (FDM) 3D printing for the manufacturing of different implantable drug delivery systems in personalized medicine and may be applied during surgical interventions.

CircATP2B4 promotes hypoxia-induced proliferation and migration of pulmonary arterial smooth muscle cells via the miR-223/ATR axis

Background: Circular RNAs (circRNAs) function as important modulators in the progression of pulmonary arterial hypertension (PAH). Here, we aimed to discover the role and working mechanism of circATP2B4 in hypoxia-induced proliferation and migration of PASMCs. Methods: The proliferation, migration and apoptosis of pulmonary arterial smooth muscle cells (PASMCs) were measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), wound healing assay and flow cytometry. The expression of circATP2B4, ATPase plasma membrane Ca2+ transporting 4 (ATP2B4), microRNA-223 (miR-223) and ATR serine/threonine kinase (ATR) was quantified by quantitative real time polymerase chain reaction (qRT-PCR). Circular RNA Interactome and microT-CDS were used to search the targets of circATP2B4 and miR-223, respectively. Dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay were used to validate the above predictions. Western blot assay was performed to detect the protein expression of ATR. Results: Hypoxia treatment promoted the proliferation and migration and impeded the apoptosis of PASMCs. A significant increase of circATP2B4 expression was observed in the serum of PAH patients and hypoxia-induced PASMCs compared with healthy volunteers and PASMCs under normoxia condition. MiR-223 is a target of circATP2B4, and the effects of circATP2B4 silencing on PASMCs were overturned by the transfection of anti-miR-223. ATR is a functional target of miR-223, and miR-223 inhibited the proliferation and migration while accelerated the apoptosis of PASMCs through targeting and down-regulating ATR. CircATP2B4 could up-regulate the level of ATR through sponging miR-223 in PSAMCs. Conclusion: CircATP2B4 potentiated hypoxia-induced proliferation and migration of PASMCs through the miR-223/ATR axis. Restoration of the level of miR-223 might be an effective therapeutic method for the treatment of PAH.

Addition of 2 equiv. of PPh3 to MnBr2 in tetrahydrofuran (THF) solution under N-2 atmosphere results in the formation of Naldini salt (PPh3)(2)MnBr2 (1). Reaction of Complex 1 and O-2, NO, and CO (with reducing agent) leads to Complex (OPPh3)(2)MnBr2 (2), (PPh3)(2)Mn(NO)Br-2 (3), and (PPh3)(2)Mn(CO)(3)Br (4), respectively. Both Complexes 2 and 4 crystallize in the triclinic space group P-1 with a = 9.94 angstrom, b = 10.11 angstrom, c = 10.53 angstrom; alpha = 65.42 degrees, beta = 63.16 degrees, and gamma = 89.22 degrees of 2 and a = 10.23 angstrom, b = 12.26 angstrom, c = 14.44 angstrom and alpha = 97.03 degrees, beta = 104.34 degrees, and gamma = 106.33 degrees of 4. The isoelectronic replacement of 3CO with 2NO yields the {Mn(NO)(2)}(8) species (PPh3)(2)Mn(NO)(2)Br (5). The single crystal of 5 is in the monoclinic space group C2/c with a = 23.17 angstrom, b = 9.62 angstrom, c = 15.92 angstrom, and beta = 114.91 degrees.

Effect of crude oil-induced water repellency on transport of Escherichia coli and bromide through repacked and physically-weathered soil columns

Knowledge of the transport and fate of pathogenic Escherichia coli, especially in the areas contaminated with crude oil, is required to assess contamination of shallow groundwater resources. The present study aims to investigate the effect of crude oil-mediated water repellency on the movement of nalidixic acid-resistant Escherichia coli strain (E. coli NAR) and bromide (Br) as an inert tracer in two soil types. The soils were contaminated at three levels of 0, 0.5 and 1% w/w of total petroleum hydrocarbons (TPHs) using crude oil. Steady-state saturated flow in the soil columns was controlled using a tension infiltrometer. Leaching experiments were conducted through the columns of repacked (un-weathered) and physically-weathered clay loam (CL) and sandy loam (SL) soils. The columns leachate was sampled at specific times for 4 pore volumes. The shape of breakthrough curves for the E coli NAR and Br depended on soil texture and structure and the TPHs level. Preferential flow in the crude oil-mediated water-repellent soils facilitated the transport of contaminants especially E. coli NAR. Filtration coefficient and relative adsorption index of bacteria were greatest in the repacked CL soils and were lowest in the weathered SL soils. Discontinuity of soil pores and lower flow velocity resulted in greater filtration of E. coli NAR in the repacked CL soil than other treatments. Physical weathering induced the formation of aggregates which reduced soil particle surfaces available for retention of water-repellent oil and contaminants. Movement of both bacteria and Br tracer in the weathered SL soil with 1% TPHs was higher than other treatments. This finding was attributed to low specific surface area, continuity of the pores and water repellency-mediated preferential pathways in the weathered SL soil columns. Our findings implied that shallow groundwater resources could be very sensitive to microbial contamination particularly in the oil-mediated water-repellent soils. (C) 2019 Elsevier Ltd.
