Antimicrofouling activity of Calotropis gigantea (L). R. Br

Milkweed or Calotropis gigantea belongs to Asclepiadaceae family having many curative principles in it. This present work aimed to study the phytochemicals prevailing in the Calotropis gigantea during the summer season by GCMS method and some of these phytochemicals tested against the collagen-binding matrix protein (4CN8) produced by the bacterial foulant through computational method. The result of GCMS analysis revealed that the prevalence of stigmasterol, alpha-amyrin, urs-12-en-24-oic acid, 3-oxo-, methyl ester, (+)-, 2(1H) Naphthalenone, 3,5,6,7,8, 8a-hexahydro-4, 8a-dimethyl-6-(1-ethylethenyl)-, Beta.-Amyrin, Bicyclo [3.1.1] heptane,2,6,6-trimethyl-, 1R-(1.alpha., 2.beta., 5.alpha.) -and 1H-Indene, 5-butyl-6-hexyloctahydro-, 2-[3-(4-tert-Butyl-phenoxy)-2-hydroxy-propylsulfanyl]-4,6-dimethyl-nicotinonitrile and cyclopropane carboxamide, 2-cyclopropyl-2-methyl-N-(1-cyclopropylethyl)- and pyridine-3-carboxamide, oxime, N-(2-trifluoro methyl phenyl). The in silico study exhibited that all the screened phytochemicals are having remarkably good interaction with the tested 4CN8 and possessing-8 to-11 Kcal/mol docking energy except pyridine-3-carboxamide, oxime, N-(2-trifluoromethylphenyl). Hence, the phytochemicals of Calotropis is a right candidate for further elaborate study to establish an eco-friendly alternative to existing toxic antifouling chemicals.

Effects of halogen ligands of complexes supported by bis(methylthioether)pyridine on catalytic activities for electrochemical and photochemical driven hydrogen evolution

Reactions of bis(methylthioether)pyridine (btep) with CuX2 (X = Br and Cl) form two new complexes, [Cu(btep)Br-2] and [Cu(btep)Cl-2], respectively, which have been determined by X-ray crystallography. Both of them can serve as catalysts for electrochemical and photochemical driven hydrogen evolution. Under an overpotential (OP) of 837.6 mV, [Cu(btep)Br-2] or [Cu(btep)Cl-2] can electrocatalyze hydrogen evolution from a neutral water with a turnover frequency (TOF) of 373 and 120 mol of hydrogen per mole of catalyst per hour (mol H-2/mol catalyst/h), respectively. Under blue light, mixing with CdS nanorods (CdS NRs) as a photosensitizer, and ascorbic acid (H(2)A) as a sacrificial electron donor, the photolysis of an aqueous solution (pH 4.5) with [Cu(btep)Br-2] or [Cu(btep)Cl-2] can provide 6180 and 5120 mol of H-2 per mole of catalyst (mol of H-2 (mol of cat)(-1)) during 48-h irradiation with an average apparent quantum yield of 16.7% and 11.0%, respectively. The results show that [Cu(btep)Br-2] shows a more efficient activity for H-2 generation than [Cu(btep)Cl-2]. Several electrochemical and photochemical measurements and analysis are carried out to study catalytic mechanism for H-2 production.

A convenient pinacol coupling of diaryl ketones with B(2)pin(2)via pyridine catalysis

A convenient, pyridine-boryl radical-mediated pinacol coupling of diaryl ketones is developed. In contrast to the conventional pinacol coupling that requires sensitive reducing metal, the current method employs a stable diboron reagent and pyridine Lewis base catalyst for the generation of a ketyl radical. The newly developed process is operationally simple, and the desired diols are produced with excellent efficiency in up to 99% yield within 1 hour. The superior reactivity of diaryl ketone was observed over monoaryl carbonyl compounds and analyzed by DFT calculations, which suggests the necessity of both aromatic rings for the maximum stabilization of the transition states.

Two isolated Zn-epsilon-Keggin decorated by pyridine-imidazole with excellent electrocatalytic and third-order NLO properties

Based on {epsilon-(PMo8Mo4O40Zn4)-Mo-V-O-VI} POM units, two novel organic-inorganic hybrids, [TBA](2)[(H3PMo8Mo4O40Zn4)-Mo-V-O-VI](2)[4-pyim](6)center dot 7H(2)O (1) (4-pyim = 4-(imidazol-2-yl)pyridine) and [(H3PMo8Mo4O40Zn4)-Mo-V-O-VI][2-pyim](4)center dot 3H(2)O (2) (2-pyim = 2-(imidazol-2-yl)pyridine), have been triumphantly gained under the hydrothermal conditions via self-assembly method. Compound 1 is made up of two Zn-epsilon-Keggin units jointed by two Zn-O bonds, which modified by three 4-pyim ligands, respectively, to form a dimer, while compound 2 consists of a Zn-epsilon-Keggin unit coordinated with four 2-pyim ligands. The coordination mode of the different ligands causes a change in the number of ligands coordinated on each Zn-epsilon-Keggin unit, resulting in the formation of dimers and monomers. What’s more, the third-order non-linear optical (NLO) properties of the two compounds were detected in detail due to the existence of a large number of conjugated organic ligands. Compound 1 has a superiority over compound 2 in NLO performance and the two-photon absorption (TPA) cross section (sigma) are 7320 GM for 1 and 1573 GM for 2, which is attributed to the fact that 1 own more conjugated organic ligands. The NLO testing results of compound 1 and 2 show that Zn-epsilon-Keggin unit can provide a good NLO response through combining with conjugated organic ligands, indicating that it is a wally choice for NLO materials. Furthermore, the electrochemistry properties of two compounds were also amply explored.

HAPPY Dyes as Light Amplification Media in Thin Films

A series of 1H amorphous tri-phenyl pyridine (HAPPY) dyes have been synthesized from luminescent triphenyl-group-containing 2-methyl-6-styryl-substituted-4H-pyran-4-ylidene derivatives in reactions with benzylamine and investigated for suitability as solution-processable light-emitting medium components in thin films for amplified spontaneous emission (ASE). Conversion of a 4H-pyrane ring into a 1H-pyridine fragment enables aggregation-induced emission enhancement (AIEE) behavior in the target products and slightly increases thermal stability, glass transition temperatures, and ASE efficiency with PLQY up to 15% and ASE thresholds as low as 46 mu J/cm(2) in neat spin-cast films, although thermal and photophysical properties are mostly dominated by the incorporated electron acceptors. Continued lasing parameter efficiency parameter improvement experiments revealed that no further optimization of HAPPY dyes by doping in polymer matrixes is required emission thresholds were lowest in pure neat films due to the AIEE phenomenon.

Hydroprocessing of Oleic Acid for Production of Jet-Fuel Range Hydrocarbons over Cu and FeCu Catalysts

In the present study, a series of monometallic Cu/SiO2-Al2O3 catalysts exhibited immense potential in the hydroprocessing of oleic acid to produce jet-fuel range hydrocarbons. The synergistic effect of Fe on the monometallic Cu/SiO2-Al2O3 catalysts of variable Cu loadings (5-15 wt%) was ascertained by varying Fe contents in the range of 1-5 wt% on the optimized 13% Cu/SiO2-Al2O3 catalyst. At 340 degrees C and 2.07 MPa H-2 pressure, the jet-fuel range hydrocarbons yield and selectivities of 51.8% and 53.8%, respectively, were recorded for the Fe(3)-Cu(13)/SiO2-Al2O3 catalyst. To investigate the influence of acidity of support on the cracking of oleic acid, ZSM-5 (Zeolite Socony Mobil-5) and HZSM-5(Protonated Zeolite Socony Mobil-5)-supported 3% Fe-13% Cu were also evaluated at 300-340 degrees C and 2.07 MPa H-2 pressure. Extensive techniques including N-2 sorption analysis, pyridine- Fourier Transform Infrared Spectroscopy (Pyridine-FTIR), X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), and H-2-Temperature Programmed Reduction (H-2-TPR) analyses were used to characterize the materials. XPS analysis revealed the existence of Cu1+ phase in the Fe(3)-Cu(13)/SiO2-Al2O3 catalyst, while Cu metal was predominant in both the ZSM-5 and HZSM-5-supported FeCu catalysts. The lowest crystallite size of Fe(3)-Cu(13)/SiO2-Al2O3 was confirmed by XRD, indicating high metal dispersion and corroborated by the weakest metal-support interaction revealed from the TPR profile of this catalyst. CO chemisorption also confirmed high metal dispersion (8.4%) for the Fe(3)-Cu(13)/SiO2-Al2O3 catalyst. The lowest and mildest BrOnsted/Lewis acid sites ratio was recorded from the pyridine-FTIR analysis for this catalyst. The highest jet-fuel range hydrocarbons yield of 59.5% and 73.6% selectivity were recorded for the Fe(3)-Cu(13)/SiO2-Al2O3 catalyst evaluated at 300 degrees C and 2.07 MPa H-2 pressure, which can be attributed to its desirable textural properties, high oxophilic iron content, high metal dispersion and mild BrOnsted acid sites present in this catalyst.

Reversible coordinative binding and separation of sulfur dioxide in a robust metal-organic framework with open copper sites

Emissions of SO2 from flue gas and marine transport have detrimental impacts on the environment and human health, but SO2 is also an important industrial feedstock if it can be recovered, stored and transported efficiently. Here we report the exceptional adsorption and separation of SO2 in a porous material, [Cu-2(L)] (H4L = 4′,4”’-(pyridine-3,5-diyl)bis([1,1′-biphenyl]-3,5-dicarboxylic acid)), MFM-170. MFM-170 exhibits fully reversible SO2 uptake of 17.5 mmol g(-1) at 298 K and 1.0 bar, and the SO2 binding domains for trapped molecules within MFM-170 have been determined. We report the reversible coordination of SO2 to open Cu(ii ) sites, which contributes to excellent adsorption thermodynamics and selectivities for SO2 binding and facile regeneration of MFM-170 after desorption. MFM-170 is stable to water, acid and base and shows great promise for the dynamic separation of SO2 from simulated flue gas mixtures, as confirmed by breakthrough experiments.

Highly Specific Coordination-Driven Self-Assembly of 2D Heterometallic Metal-Organic Frameworks with Unprecedented Johnson-type (J(51)) Nonanuclear Zr-Oxocarboxylate Clusters

The quest for new and unique polynuclear metal-oxocarboxylate clusters has led to a continual boom of highly connected and robust metal-organic frameworks (MOFs) with intriguing properties. In this work, by virtue of a highly specific coordination-driven cluster rearrangement process of a presynthesized trinuclear zirconocene-based tripodal metallo-pyridine ligand, we realized the preparation of the first two 2D heterometallic MOFs incorporating unprecedented Johnson-type (J(51)) nonanuclear Zr-oxocarboxylate clusters, as unambiguously uncovered by single-crystal X-ray crystallography. The resultant two charged frameworks feature counteranion-dependent 3,6-c kgd (JMOF-1) and 3,12-c 3,12L4 (JMOF-2) nets that are formed by octahedral and hexagonal prismatic Zr-9 molecular building blocks (MBBs), respectively. In addition, JMOF-2 shows promise for the purification of acetylene from CO2 and C2H4, with LAST selectivities of about 12 and 8, respectively, at 298 K and 1 bar, as well as remarkable iodine capture capacity of up to 2.4 g g(-1).

Polarizable Frozen Density Embedding with External Orthogonalization

We report a polarizable subsystem density functional theory to describe electronic properties of molecules embedded on a metal cluster. Interaction between the molecule and metal cluster is described using frozen density embedding (FDE). Substituting the nonadditive kinetic potential (NAKP) by approximate functionals is circumvented by enforcing external orthogonality (EO) through a projection operator. The computationally expensive freeze/thaw (FT) cycles are bypassed by including a polarization term in the embedding operator. Furthermore, the combination of polarization and EO permits supermolecular basis set calculations, which was not possible for strongly interacting systems with existing kinetic energy functionals. To test the method, we described the ground state density of pyridine, water, and benzene on a silver cluster. Performing FT on top of EO results in exact density embedding for this category of systems and is thus used for benchmarking the method. We find that the density is reproduced to within 0.15e, and the dipole and quadrupole moments are within 18% of the reference points for subsystem separations ranging from bonding to noninteracting distances. Additionally, our formalism allows the flexibility of incorporating different density functionals to the molecular and the metallic subsystems reducing the overall computational cost.
