Graphene oxide/multi-walled carbon nanotubes nanocompsite polyamide nanofiltration membrane for dyeing-printing wastewater treatment

Graphene oxide (GO)/multi-walled carbon nanotubes (MWCNTs) modified nanofiltration (NF) membranes were successfully fabricated by interfacial polymerization of piperazine (PIP) and 1,3,5-benzenetricarbonyl trichloride (TMC). Compared with the pristine polyamide (PA) membrane and GO membrane, the typical structure of the granular protrusions on the surface of the GO/MWCNTs membrane gradually disappeared, and a regular ordered morphology appeared. The membrane thickness and surface roughness were increased according to the results of field emission scanning electron microscopy (FE-SEM) and atomic force microscopy (AFM). The contact angle of GO/MWCNTs NF membranes progressively decreased from 57 degrees to 23 degrees, indicating the enhancement of surface hydrophilicity. The best NF performance was achieved when the ratio of GO to MWCNTs was 6:3 (G-M-3). The water flux was 55.6 L/m(2).h, which was 33.7% higher than that of the GO membrane, and the rejection rate for Na(2)SO(4)was maintained at approximately 94%. Both modified NF membranes could treat actual dyeing-printing wastewater effectively. The anti-fouling performance of G-M-3 was better than that of G3. Therefore, GO/MWCNTs-modified NF membranes have a good application prospects in the field of wastewater treatment and water purification.

Spirocyclic Nitroxide Biradicals: Synthesis and Evaluation as Dynamic Nuclear Polarizing Agents

A method for the synthesis of rigid nitroxide biradicals with various spatial orientations between the radical centers is reported. Diketones were employed as substrates for tin amine protocol (SnAP) reagents to provide the parent spirocyclic diamines. Oxidation by peroxyacids provided the corresponding nitroxide biradicals. A set of four different biradicals with various interelectron distances and torsion angles between the radical planes was synthesized using this method. The exact geometries were determined by X-ray crystallography and the biradicals were investigated by EPR spectroscopy and evaluated for their dynamic nuclear polarization (DNP) performance. H-1-DNP enhancements in the range of 1.2-2.1 at 14.1 Tesla (600 MHz spectrometer) were achieved. This synthetic methodology opens a promising alternative to access nitroxide biradicals with various torsional angles and inter radical distances.

An Efficient Solid-Liquid Biphasic Solvent for CO2 Capture: Crystalline Powder Product and Low Heat Duty

A nonaqueous, phase-change absorbent of 2-amino-2-methyl-1-propanol (AMP)/piperazine (PZ) and environmentally friendly solvent dipropylene glycol dimethyl ether (DME) fixes a number of issues suffered by a solid-liquid biphasic solvent, such as high viscosity of the saturated solution and difficult separation and regeneration of the viscous solid. The solid phase occupies 43% of the total volume while attributes about 94% of the total loading (0.87 mol mol(-1)) of the solution. Beside the formation of AMP-carbamate and PZ-carbamate according to zwitterions mechanism, the coupling products of AMP/PZ-carbamate are also found in the crystal, which helps to reduce the desorption temperature during the regeneration. Because of low solubility, self-aggregation, and high lattice energy in DME, the CO2 products precipitate and form a white crystalline powder in the lower phase of the solution. Meanwhile, the solid precipitation helps the bulk solution to keep a lower partial pressure and higher diffusivity of CO2, conforming a perfect performance of CO2 capture into the biphasic solvent. The regeneration heat duty of the solvent (1.61 GJ t(-1) CO2) was approximately 57% less than that of the benchmark monoethanolamine (MEA) because of its perfect performance on CO2 capture, such as high absorption loading, high regeneration efficiency, and low amount of rich phase required for regeneration. The novel absorbent has a great potential for green and sustainable CO2 capture.

Synthesis of novel cytotoxic tetracyclic acridone derivatives and study of their molecular docking, ADMET, QSAR, bioactivity and protein binding properties

Acridone based synthetic and natural products with inherent anticancer activity advancing the research and generating a large number of structurally diversified compounds. In this sequence we have designed, synthesized a series of tetracyclic acridones with amide framework viz., 3-(alkyloyl/ aryloyl/ heteroaryloyl/ heteroaryl)-2,3-dihydropyrazino[3,2,1-de]acridin-7(1H)-ones and screened for their in vitro anti-cancer activity. The in vitro study revealed that compounds with cyclopropyl-acetyl, benzoyl, p-hydroxybenzoyl, p-(trifluoromethyl)benzoyl, p-fluorobenzoyl, m-fluorobenzoyl, picolinoyl, 6-methylpicolinoyl and 3-nicotinoyl groups are active against HT29, MDAMB231 and HEK293T cancer cell lines. The molecular docking studies performed for them against 4N5Y, HT29 and 2VWD revealed the potential ligand-protein binding interactions among the neutral aminoacid of the enzymes and carbonyl groups of the title compounds with a binding energy ranging from -8.1394 to -6.9915 kcal/mol. In addition, the BSA protein binding assay performed for them has confirmed their interaction with target proteins through strong binding to BSA macromolecule. The additional studies like ADMET, QSAR, bioactivity scores, drug properties and toxicity risks ascertained them as newer drug candidates. This study had added a new collection of piperazino fused acridone derivatives to the existing array of other nitrogen heterocyclic fused acridone derivatives as anticancer agents.

Altitude impact on the chemical profile and biological activities of Satureja thymbra L. essential oil

Background: Several agricultural or environmental factors affect plants’ chemical and pharmacological properties. Methods: In this study, the essential oil of Libyan Satureja thymbra was isolated from plants collected during two successive years at two different altitudes; Wasita (WEO) and Safsaf (SEO), 156 and 661m above sea level, respectively. Results: GC/MS allowed the identification of 21 and 23 compounds, respectively. Thymol prevailed in WEO (26.69%), while carvacrol prevailed in SEO (14.30%). Antimicrobial activity was tested by agar-well diffusion method, and MIC/MLC values were determined by broth dilution method. Values of MIC/MLC were 0.125/0.25 mu g/ml for SEO against S. aureus, P. mirabilis and K. pneumonia and for WEO against B. subtilus. It was observed that plants growing at lower altitude in Wasita locality had better antifungal activity, while those growing at higher altitude at Safsaf locality had better antibacterial activity. Both essential oils had a better anthelmintic activity than the standard piperazine citrate against a tested earthworm. However, SEO oil had a significantly higher anthelmintic activity than WEO. Cytotoxicity of the oils tested using SRB assay on human breast cancer (MCF-7) and colon cancer cell lines (HCT-116) showed better activity for SEO, especially against HCT-116 with IC50 2.45 +/- 0.21 mu g/ml. Conclusions: Thus, altitude is an important factor that should be considered as it affected the yield, composition and biology of the plant extracts.

Role of aromatic vs. aliphatic amine for the variation of structural, electrical and catalytic behaviors in a series of silver phosphonate extended hybrid solids

Four inorganic-organic hybrid silver phosphonate compounds, [Ag(C10H8N2)(H(4)hedp)] (1), [Ag-2(C10H8N2) (H(3)hedp)]center dot 2H(2)O (2), [C-4 H12N2HAg4(H(2)hedp)(2)] (3) and (C4H12N2][Ag-10(H(2)hedp)(4)(H2O)(2)]center dot 2H(2)O (4) (H(5)hedp = 1-hydroxyethane-1,1-diphosphonic acid), have been prepared by virtue of the variable amine-directed hydrothermal strategy. The subsequent roles of coordinated aromatic amine (4,4′-bipyridine) and coordination-free templated aliphatic amine (piperazine) are studied. The connectivity of the silver ions, diphosphonate units (hedp) and bipyridine moiety can give rise to the one-dimensional structure of 1 and two-dimensional layer structure of 2. In contrast, the silver ions and diphosphonate units are connected to form the tetrameric and pentameric silver cluster units in compound 3 and 4, respectively. Such clusters are rare examples of fundamental building units in the piperazine templated two-dimensional silver based layer structures. The room temperature dielectric studies show the extremely high dielectric permittivity of the amine templated compounds (3 and 4) compared to amine coordinated structures (1 and 2). The synthesized compounds also participate in various heterogenous catalytic reactions acting as active Lewis acid catalysts that are observed for the first time in the amine-templated metal organophosphonates. The observed band gaps and dielectric values suggest that compounds 3 and 4 are more promising candidates for electronic applications, while compounds 1 and 2 are comparatively better Lewis acid catalysts.

Synthesis, spectroscopic, DFT, HSA binding and docking studies of new 1,5-bis(4-chlorophenyl)-3-(2-(4-methylpiperazin-1-yl)quinolin-3yl)pentane-1,5-dione

1,5-Bis(4-chlorophenyl)-3-(2-(4-methylpiperazin-1-yl)quinolin-3-yl)pentane-1,5-dione was synthesised and characterised using single-crystal X-ray Crystallography, FT-IR, H-1-NMR, C-13-NMR and UV-Visible spectroscopy. DFT calculations were performed at the B3LYP/6-311++G (d.p) level of theory in the gas phase. Frontier Molecular Orbitals (FMO) yielded HOMO-LUMO energy as: E-HOMO = -6.015 eV, E-LUMO = 2.525 eV and energy gap, similar to E-gap = 3.490 eV. Fukui Function Analysis (FFA) indicated the reactive sites for electrophilic, and nucleophilic attack. The molecule’s electrophilic addition site is 4-N in the piperazine group with a value of 0.020. The site for nucleophilic attack is both 13-C and 15-C in the quinoline group with values of 0.02 and 0.031 respectively. The biological activity was elucidated by molecular docking studies that gave a similar to G value for HSA binding of -26.44 kJ mol(-1) which is approximately similar to the experimental value obtained from emission spectral data of -32.15 kJ mol(-1).

Three-channel capillary nanofiltration membrane with quaternary ammonium incorporated for efficient heavy metals removal

High-performance nanofiltration (NF) membranes have profound implications for water purification. Here, we reported a novelty polyamide NF membrane through introducing bis (2-hydroxyethyl) dimethyl-ammonium chloride (BHDA) in interfacial polymerization (IP) process on three-channel substrate membrane. This new monomer bearing abundant quaternary ammonium (N+) and hydroxyl could participate in the reaction between piperazine (PIP) and trimesoyl chloride (TMC). Then, not only was positive charge introduced into the NF membrane, but the hydrophilic of the resultant NF membrane was also significantly improved. Thus, the as-prepared PIP/BHDA-TMC (MPQ) membrane exhibited enhanced pure water flux (12.9 L.m(-2).h(-1).bar(-1)) which is 2.4 times as high as that of the PIP-TMC (MP) membrane, coupled with the salt rejection sequence as MgSO4 (93.46%) > Na2SO4 (91.61%) > MgCl2 (88.15%) > NaCl (22.03%). Meanwhile, MPQ exhibited a promising separation performance to various heavy metal salts (96.43% CuSO4, 96.16% ZnSO4, 91.69% Cu(NO3)(2), 89.69% ZnCl2, 88.37% Pb(NO3)(2)). The stability of MPQ was tested with simulated wastewater, and the results illustrated that it has a potential applicability for heavy metals removal.

CO2 capture cost saving through waste heat recovery using transport membrane condenser in different solvent-based carbon capture processes

In this study, the waste heat from the hot stripping gas was recovered by adopting the transport membrane condenser (TMC) in the monoethanolamine (MEA)-, diethanolamine (DEA)-, piperazine (PZ)- and potassium glycinate (PG)-based rich-split modified carbon capture processes. A 220-h test showed that TMC can exhibit a good stability on the waste heat recovery performance. The PZ-based TMC-modified rich-split process (i.e., PZ-case) achieved a highest waste heat recovery performance, followed by the PG-case, MEA-case and DEA-case. A strong linear relationship between the heat and water fluxes was observed during the waste heat recovery. Three scenarios were considered for comparing the CO2 capture cost savings of 4 cases. When the TMC area was fixed meaning the same additional investment of rich-split modification, PZ-case gained the highest CO2 capture cost saving ($6.40/t-CO2), followed by PG, MEA- and DEA-case. When a fixed waste heat recovery performance of 600 kJ/kg-CO2 was required for obtaining the same revenue after rich- split modification, PZ- and PG-case obtained the same CO2 capture cost saving of $4.22/t-CO2. Moreover, when the reboiler duty reduction potential was aimed at 15%, PG-case achieved the maximum CO2 capture cost saving ($4.56/t-CO2). (C) 2020 Elsevier Ltd. All rights reserved.
