Preparation and high CO2/CH4 selectivity of ZSM-5/Ethyl cellulose mixed matrix membranes

It is known that natural gas is extracted with a large amount of CO2, which reduces the amount of heat generated during the combustion of natural gas. How to remove some of the CO2 from the natural gas is a problem that needs to be solved. The significant breakthroughs of the membrane technology, specifically the mixed matrix membrane (MMM) has revealed a promising CO2/CH4 separation performance. In this study, a series of ZSM-5/EC mixed matrix membranes with ethyl cellulose (EC) as matrix and ZSM-5 as inorganic dispersant in tetrahydrofuran were prepared under high speed and ultrasonic vibration-assisted, the ZSM-5/EC membranes were fabricated by using the casting solution. The successful ZSM-5/EC mixed matrix membranes were confirmed by Fourier transfer infrared (FTIR) and Scanning electron microscopy (SEM). The ZSM-5/EC membranes exhibited good membrane forming ability, heat resistance and mechanical properties; The CO2/CH4 selectivity of the ZSM-5/EC membranes were 10.7, 15.4, 19.7, 25.5 and 11.7, respectively, increased up to 1.3, 1.9, 2.4, 3.1 and 1.4 times as compared to pure EC (8.20) with a feed composition of 50:50 for CO2/CH4.

Facile preparation of fluoroalkyl end-capped vinyltrimethoxysilane oligomer/alpha, omega-dihydroxy-terminated poly(dimethylsiloxane) composite rubber: application to effective removal of fluorinated aromatic compound from aqueous methanol solution by fluoroalkylated silicone composite rubber

Fluoroalkyl end-capped vinyltrimethoxysilane oligomer [R-F-(CH2CHSiOMe)(3))(n)-R-F;n = 2, 3; R-F = CF(CF3)OC3F7: R-F-(VM)(n)-R-F] undergoes the sol-gel reactions in the presence of alpha, omega-dihydroxy-terminated poly(dimethylsiloxane) [HO-(SiMe2O)(n)H:HPDMS] under non-catalytic conditions to provide the crosslinked R-F-(VM)(n)-R-F/HPDMScomposite rubber in quantitative isolated yields. Especially, we can isolate the expected composite rubber through the sol-gel reactions, in which the contents of the R-F-(VM)(n)-R(F)oligomer based on employed oligomer andHPDMSare greater than 0.16%. In contrast, traditional silane coupling agents such as tetraethoxysilane, methyltrimethoxysilane and triethoxy-1H,1H,2H,2H-tridecafluoro-n-octylsilane were unable to afford the expected composite rubber through the sol-gel reactions withHPDMSunder similar conditions. The fluoroalkylated silicone composite rubber thus obtained gave no swelling behavior toward water, dimethyl sulfoxide and methanol; however, the composite rubber was found to display the higher swelling characteristic for toluene, hexane and tetrahydrofuran, especially for fluorinated aliphatic solvents. Interestingly, it was demonstrated that the fluoroalkylated silicone composite rubber swollen with hexane can adsorb a variety of aromatic compounds in aqueous methanol solutions. More interestingly, we found that the fluoroalkylated silicone composite rubber can exhibit an excellent adsorption ability toward the fluorinated aromatic compounds such as 2 ‘, 3 ‘, 4 ‘, 5 ‘, 6 ‘-pentafluoroacetophenone, compared to that of the corresponding non-fluorinated one.

Bioaugmenting the poplar rhizosphere to enhance treatment of 1,4-dioxane

1,4-Dioxane is a highly mobile and persistent groundwater pollutant that often forms large dilute plumes. Because of this, utilizing aggressive pump-and-treat and ex-situ technologies such as advanced oxidation can be prohibitively expensive. In this study, we bioaugmented the poplar rhizosphere with dioxane-degrading bacteria Mycobacterium dioxanotrophicus PH-06 or Pseudonocardia dioxanivorans CB1190 to enhance treatment of 1,4-elioxane in bench-scale experiments. All treatments tested removed 10 mg/L dioxane to near health advisory levels (<4 mu g/L). However, PH-06-bioaugmented poplar significantly outperformed all other treatments, reaching <4 mu g/L in only 13 days. Growth curve experiments confirmed that PH-06 could not utilize root extract as an auxiliary carbon source for growth. Despite this limitation, our findings suggest that PH-06 is a strong bioaugmentalion candidate to enhance the treatment of dioxane by phytoremediation. In addition, we confirmed that CB1190 could utilize both 1.4-dioxane and root extract as substrates. Finally, we demonstrated the large-scale production of these two strains for use in the field. Overall, this study shows that combining phytoremediation and bioaugmentation is an attractive strategy to treat dioxane-contaminated groundwater to low risk-based concentrations (similar to 1 mu g/L).

Mild reduction with silanes and reductive amination of levulinic acid using a simple manganese catalyst

A manganese-based catalytic system using the commercially available complex [Mn(CO)(5)Br] was studied for the selective reduction of levulinic acid (LA) to 2-methyl-tetrahydrofuran (MTHF). We further studied the production of pyrrolidines via its reductive amination using silanes (phenylsilane and tetramethyldisiloxane). The results showed high efficiency and selectivity for this reaction leading to high yields using mild reaction conditions.

Application of 5061-21-2, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 5061-21-2 is helpful to your research.

Novel electrospun polyurethane scaffolds containing bioactive glass nanoparticles

In the present study, polyurethane (PU) nanocomposite scaffolds containing bioactive glass nanoparticles (BG-NPs) were successfully fabricated through the electrospinning process. The BG-NPs were synthesized through the sol-gel method. PU solutions (10% w/v) containing different weight percentages of the BG-NPs (5, 10 and 15 wt.%) in dimethylformamide/tetrahydrofuran were prepared. To determine both the size of BG-NPs and the diameter of the nanofibers, transmission electron microscopy and scanning electron microscopy were carried out. The surface morphology, mechanical properties, bioactivity and degradation rate of the scaffolds were studied. Fourier transform infrared spectroscopy, X-ray diffraction and energy-dispersive X-ray spectroscopy confirmed the presence of BG within the scaffolds. The tensile strength of nanocomposite scaffolds was in the range 5-8 MPa, which is in good agreement with the tensile strength of cancellous bone tissue. MG63 cells attached to and proliferated well within the scaffolds; therefore, cellular growth was also improved in the nanocomposite scaffolds. Based on the results, the novel PU/BG-NP (10 wt.%) nanocomposite scaffold has a great potential to be applied in cancellous bone tissue engineering.

Thin-Film Self-Assembly of Block Copolymers Containing an Azobenzene-Based Liquid Crystalline Polymer and a Poly(ionic liquid)

By combining reversible addition-fragmentation chain transfer (RAFT) with postfunctionalization and ion exchange, we synthesized a series of block copolymers (BCPs) containing an azobenzene-based liquid crystalline (LC) polymer (PAzo) and an imidazolium-containing poly(ionic liquid) (PIL, PVB(TFSI)) with the volume fraction of PIL (f(PIL)) values ranging from 15.9% to 69.9%. The samples obtained self-assemble into hexagonally packed cylinders (HEX), lamellae (LAM), and the mixed phase with coexisting HEX and LAM. The thin-film self-assembly of the samples PAzo(101)-b-PVB(TFSI)(22) and PAzo(101)-b-PVB(TFSI)(67) was studied systematically. We investigated the assembled structures of the thin films with various initial thicknesses after thermal annealing (145 degrees C for 12 h) or mixed solvent vapor annealing with tetrahydrofuran and n-hexane. Thin films with large-scale uniaxial PIL nanocylinders were obtained, which will greatly broaden the application of IL-based BCPs. Inverse phases were also observed for the thin films with thicknesses less than similar to 120 nm. The different mechanisms of the formation of inverse nanostructures formed in the thinner films under the thermal annealing and mixed solvent vapor annealing conditions were also elucidated.

Excitation-Wavelength-Dependent Light-Induced Electron Transfer and Twisted Intramolecular Charge Transfer in N,N-Bis(4 ‘-tert-butylbiphenyl-4-yl)aniline Functionalized Borondipyrromethenes

A series of bis(4’-tert-butylbiphenyl-4-yl)aniline (BBA) functionalized borondipyrromethene (BODIPY) dyads, Dyads 1-3, containing the BBA group tethered to BODIPY moiety either directly or through a phenyl or alkynyl phenyl spacers are synthesized, and the light-mediated charge transfer within the chromophores has been systematically investigated. The crystal structure of Dyad-1 showed a tilt of 44.2 degrees between the BODIPY and BBA molecular planes and intermolecular C-H-pi interactions with these moieties. Cyclic voltammetric and computational studies showed that the BBA moiety can act as the electron donor (D) and BODIPY as the electron acceptor (A) and the optical absorption studies revealed that an increase in the conjugation of the linker from Dyad-1 to Dyad-2 resulted in bathochromic shifts. Steady-state fluorescence studies involving photoexcitation of the BBA moiety at 326 nm resulted in the decrease in fluorescence intensity of the BBA, indicating the possibility of sequential occurrence of faster photoinduced energy transfer (PEnT) followed by the photoinduced electron transfer (PET) or solely PET within the dyads, and the driving forces of the charge separation were calculated to be exothermic in all of the employed solvents. Parallel time-resolved fluorescence experiments involving the excitation of BBA moiety also supported the occurrence of charge separation in these dyads. Interestingly, excitation of the BODIPY moiety of Dyad-1 and Dyad-2 at 490 nm in solvents of increasing polarity leads to a red-shifted BODIPY emission with weakened intensity. This spectral behavior indicated the occurrence of emission from the locally excited (LE) state in nonpolar solvents, whereas formation of an LE state followed by the rotation of the chromophores at the D-A bond leads to a low energy twisted intramolecular charge transfer state (TICT), resulting in a charge-separated state BBA+center dot-BODIPY (-)center dot in polar solvents. Furthermore, the hydrophobicity studies involving the solutions of dyads in admixtures of polar tetrahydrofuran (THF) and nonpolar hexanes revealed that when the fraction of hexanes in these mixtures is increased, the emission of BODIPY moiety was observed to be blue-shifted and exhibited enhanced intensity supporting the occurrence of TICT in these dyads.

Bio-Guided Isolation of Acetogenins from Annona cherimola Deciduous Leaves: Production of Nanocarriers to Boost the Bioavailability Properties

Annonaceous acetogenins (ACGs) are lipophilic polyketides isolated exclusively from Annonaceae. They are considered to be amongst the most potent antitumor compounds. Nevertheless, their applications are limited by their poor solubility. The isolation of ACGs from Annona cherimola leaves, an agricultural waste, has not been reported to date. Molvizarin (1) cherimolin-1 (2), motrilin (3), annonacin (4) and annonisin (5) are isolated for the first time from A. cherimola deciduous leaves. Annonacin was found to be four- and two-times more potent in tumoral cells (HeLa, 23.6% live cells; IGROV-1, 40.8% live cells for 24 h) than in HEK-293 at 50 mu M (24 h, 87.2% live cells). Supramolecular polymer micelles (SMPMs) were synthesized to encapsulate the major ACG isolated, annonacin, in order to improve its solubility in aqueous media. The bioavailability of this compound was increased by a factor of 13 in a simulated human digestive system when compared with free annonacin and an encapsulation efficiency of 35% was achieved. In addition, the cytotoxic activity of SMPMs that hosted annonacin (100 mu M, 24 h, 5.8% live cells) was increased compared with free annonacin in water (100 mu M, 24 h, 92% live cells). These results highlight the use of by-products of A. cherimola, and their pure compounds, as a promising source of anticancer agents. The use of SMPMs as nanocarriers of ACGs could be an alternative for their application in food field as nutraceutical to enhance the administration and efficacy.

Residues characteristics and structural evolution of Naomaohu coal during a mild direct liquefaction process

Direct coal liquefaction (DCL) is an important way of coal conversion and is important to the global energy industry. In this paper, a typical liquefied coal-Naomaohu coal (NMHC)-was liquefied under mild conditions (400 degrees C, initial H-2 pressure of 3 MPa), and a NMHC conversion of 90.6% was obtained with an oil+gas yield of 65.1%. In the DCL process, the solid particles of coal and its residues are not only reactants but also carriers of catalysts of DCL. To study the structural characteristics of these residues, the reaction mixture was extracted with n-hexane and tetrahydrofuran (THF), separately, yielding n-hexane insoluble residues (Re-HEIS) and THF insoluble residues (Re-THFIS). Several patterns of the reaction progresses were identified. First, the particle sizes of Re-HEIS and Re-THFIS have a decreasing trend, and the particle surface becomes loose and porous while raw coal has a relatively flat surface. Second, most of the aliphatic structure and some small aromatic compounds can gradually split off from coal skeleton structure, and the condensation degree of aromatic clusters in residues increases with the aromatic condensation degree of Re-THFIS being higher than that of Re-HEIS. Third, the contents of carbonyl carbon and oxygen-attached carbon decrease while methylene chain and side chain of aromatic clusters are broken. Lastly, the aromatic structure of Re-THFIS becomes regular, and the graphitization degree increases, while the pyrolysis rate slows down. These results of element analysis show that the H/C of Re-HEIS is larger than that of Re-THFIS, which implies that preasphaltene and asphaltene are relatively rich in hydrogen.

Effect of different molecular architectured POSS-fluoropolymers on their self-assembled hydrophobic coatings

A total of 1/2/4/6-armed molecular architectured polyhedral oligomeric silsesquioxane (POSS) fluoropolymers were synthesized via atom transfer radical polymerization (ATRP) by linear (L), dicephalus (D), four-arm (T), and six-arm (S) initiators initiating same content of methyl methacrylate (MMA), methacrylate POSS (MA-POSS), and dodecafluoroheptyl methacrylate (DFHM). The obtainedL/D/T/S-(PMMA-b-PMAPOSS-b-PDFHM)(1/2/4/6) had increased molecular weight with arm increase. Driven by the stereo-hindrance and curvature effects of segments in tetrahydrofuran (THF), they assembled into the decreased spherical core-shell micelles (250-100 nm) with arm increase as PMA-POSS/PDFHM core and PMMA shell. Because of easy surface migration of fluorine-containing groups in small micelles, the casted film byS-(PMMA-b-PMAPOSS-b-PDFHM)(6) performed the fluorine-rich (46.44%) and rough (5.41 nm) surface, and therefore with the hydrophobic (112 degrees) and low water adsorption surface (1522 ng/cm(2)). Also, POSS-fluoropolymers obtained the enhanced thermostability with arm increase. It is believed that this research will provide a bright view for design and application of POSS-fluoropolymers.
