In view of the disadvantages of concentration polarization and trade-off effects in the application of membrane in desalination field, oxide-nano graphene oxide/polyamide (O-NGO/PA) loose intermediate layer and PA ultra-thin dense layer were introduced to fabricate PA/O-NGO/polyphenylene sulfide composite membrane with sandwich structure via multi-step interfacial polymerization (MS-IP) method. The selective permeation mechanism of ultrathin layer produced by different aqueous monomers (PIP and MPD) was studied, the effect of its physicochemical structure on the relief of concentration polarization phenomenon and the breakthrough of trade-off effect was analyzed. The ultra-thin and dense PA layer mainly played the role of interception and shortened the water molecular penetration path. In the retention test of metal salt solution, compared with the rough surface, it was found that the smooth surface was more conducive to the diffusion of intercepted metal ions into the feed solution, thus alleviating the concentration polarization phenomenon.

COA of Formula: C13H10O. I found the field of Science & Technology – Other Topics; Materials Science very interesting. Saw the article Ultrahigh Flux and Strong Affinity Poly(N-vinylformamide)-Grafted Polypropylene Membranes for Continuous Removal of Organic Micropollutants from Water published in 2021, Reprint Addresses Chen, XN (corresponding author), Beijing Univ Chem Technol, Beijing Lab Biomed Mat, Beijing 100029, Peoples R China..

The rapid and effective removal of organic micropollutants (OMPs) from water remains a huge challenge for traditional water treatment techniques. Compared with powder adsorbents such as polymers and nanomaterials, the free-standing adsorptive membrane is possible for large-scale applications and shows promise in removing OMPs. Herein, inspired by aquatic plants, a novel free-standing adsorptive membrane (NPPM) with high water flux, strong adsorption affinity, and excellent reproducibility was prepared by one-step UV surface grafting. N-Vinylformamide (NVF) was employed to introduce multiple hydrophilic and hydrogen bonding sites on the surface of commercial polypropylene fiber membranes (PPM). The NPPM exhibits excellent water permeability and ultrahigh water flux (up to 40 000 L/(m(2) h)) and could continuously remove a broad spectrum of OMPs from water. Its adsorption performance is 5-100 times higher than that of PPM and commercial membranes. Even in natural water sources such as tap water and river water, the NPPM shows unchanged adsorption performance and high OMPs removal efficiency (>95%). Notably, the NPPM has excellent regeneration performance and can be regenerated by hot water elution, which provides an environmentally friendly regeneration method without involving any organic solvent. Moreover, the synergy between hydrogen bonding and hydrophobic interaction is revealed, and the hydrophobic interaction provided by the hydrophobic substrate is proved to play a fundamental role in OMPs adsorption. The strong hydrogen bonds between the grafts and the OMPs are demonstrated by variable-temperature FTIR spectroscopy (vt-FTIR), C-13 nuclear magnetic resonance spectroscopy (C-13 NMR), and simulation calculations. The strong hydrogen bonds could increase the enthalpy change and enhance the adsorption affinity, so the NPPM has a strong adsorption affinity, which is 100 times that of similar adsorption membranes. This study not only presents an adsorptive membrane with great commercial potential in the rapid remediation of a water source but also opens a pathway to develop an adsorptive membrane with high water flux and strong adsorption affinity.

Three new arene-ruthenium(II) complexes were prepared by treating [{RuCl(mu-Cl)(eta(6)-arene)}(2)] (eta(6)-arene = p-cymene) dimer with tri(2-furyl)phosphine (PFu(3)) and 1,3,5-triaza-7-phosphaadamantane (PTA), respectively to obtain [RuCl2(eta(6)-arene)PFu(3)] [Ru] -1, (RuCl(eta(6)-arene)(PFu(3))(PTA)]BF4 [Ru] -2 and HtuCl(eta(6)-arene)(PFu(3))(2)]BF4 [Ru] -3. All the complexes were structurally identified using analytical and spectroscopic methods including single-crystal X-ray studies. The effectiveness of resulting complexes as potential homogeneous catalysts for selective hydration of different nitriles into corresponding amides in aqueous medium and air atmosphere was explored. There was a remarkable difference in catalytic activity of the catalysts depending on the nature and number of phosphorus-donor ligands and sites available for catalysis. Experimental studies performed using structural analogues of efficient catalyst concluded a structural-activity relationship for the higher catalytic activity of [Ru] -1, being able to convert huge variety of aromatic, heteroaromatic and aliphatic nitriles. The use of eco-friendly water as a solvent, open atmosphere and avoidance of any organic solvent during the catalytic reactions prove the reported process to be truly green and sustainable.

An efficient green method has been developed for the cascade multi-component Hantzsch reaction of acridinediones and biscoumarins using Fe3O4@SiO2@Ni-Zn-Fe layered double hydroxide (LDH). Nano Ni-Zn-Fe LDH immobilized on silica-layered magnetite was synthesized via a simple co-precipitation procedure, and characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) and transmission electron microscopy (TEM). The nanocatalyst has the usual features of Fe3O4@SiO2 and Ni-Zn-Fe LDH. Moreover, it contains magnetism properties which is related to the presence of magnetite in the nanocatalyst and can be easily separated from the reaction mixture with an external magnetic field. Subsequently, the nanomagnetic-LDH was used to evaluate catalytic activity with the tandem synthesis of acridinedione and biscoumarin derivatives. The mesoporous catalyst showed excellent performance for multi-component reactions between aromatic aldehydes, 4-hydroxycoumarin, and dimedone and ammonium acetate. Acridinediones were provided within 15-35 min in 80-96% yields under solvent-free conditions in 70-80 degrees C and also, biscoumarins were obtained within 1-40 min in 87-95% yields under reflux conditions in water. The present study includes noteworthy advantages of mild reaction conditions, short times of reaction, absence of hazardous and expensive organic solvents and reagents, presence of water as an eco-friendly solvent, using green nanomagnetic-LDH and the ability to recycle the nanocatalyst.

Herein, the facile photografting coating method was used to develop a novel metal biochelator film by covalent immobilization of citric acid (CA) onto polypropylene (PP) surface. First, PP film underwent a surface modification by UV-grafting of glycidyl methacrylate (GMA) in the presence of benzophenone (BP). The concentrations of GMA (bifunctional monomer) and BP (photoinitiator) were appropriately optimized to achieve the breath-figure-array structure and brush-like grafting configuration with a high availability of the reactive oxirane ring. Subsequently, CA was immobilized onto the PP-g-GMA surface via the ring-opening reaction to obtain the biochelator film (PP-g-GMA-g-CA). Fourier-transform infrared spectroscopy and solid state C-13 nuclear magnetic resonance spectroscopy elucidated the chemical structure and grafting mechanism of grafted samples. X-ray photoelectron spectroscopy was used to detect the chemical composition of the surface of the grafted samples, by which the grafting density was relatively estimated. In addition, the uniformity of the grafting pattern and morphology of the grafting unit were observed using scanning electron microscopy and atomic force microscopy. Furthermore, the carboxylic acid density of the biochelator film (PP-g-GMA-g-CA) was quantified using a toluidine blue O assay, in which approximately 327 +/- 58 nM carboxylic acid was detected per each film. The metal chelating activity of the film was also investigated using the colorimetric ferrozine assay, by which PP-g-GMA-g-CA film chelated approximately 215 +/- 11 nM of Fe3+. Therefore, this newly developed system can be used as a versatile metal biochelator in a wide range of biomedical, cosmetic, and packaging applications.

Chloroform, a regulated disinfection by-product in water, is often generated during chlorination disinfection treatment. However, the formation of chloroform is heavily dependent on the molecular structures of precursors. Moreover, compounds containing ketone moiety are ubiquitous in water environments. However, it is unclear if they can generate chloroform during chlorination. In this study, 14 benzophenones (BPs), efficient and widely used UV filters, with different substituents were selected to explore chloroform formation during chlorination. All 14 BPs generated chloroform, with yields dependent on their molecular structures and operational conditions. Compounds 2,2′,4,4′-tetrahydroxy-BP and benzophenone produced the highest and lowest chloroform of 0.313 and 0.013 g/g, respectively, corresponding to the fastest and slowest formation rate constants of 1.41 x 10(-1) and 2.71 x 10(-2) min(-1). Alkaline conditions and high chlorine dosages were favorable to chloroform formation. Three reactions played key roles in chloroform formation from BPs: (1) chlorine initiated Baeyer Villiger oxidation converted ketone moieties of BP molecules into esters; (2) the esters further underwent hydrolysis and formed phenolic and benzoic products; and (3) benzoic acids underwent decarboxylation and hydrolysis to form phenolic products. Subsequently, these phenolic products could further generate chloroform in the chlorination system. More importantly, BPs could generate chloroform in the ambient water matrices during practical chlorination treatment. This work emphasized the critical role of Baeyer-Villiger oxidation for chloroform formation, implying that pollutants containing aromatic ketone moieties generate chloroform during chlorination disinfection, and their potential risk should therefore be reviewed.

Propylene polymerization titanium-magnesium catalysts (TMCs) were synthesized from different magnesium compounds with diphenylketone (DPK) as the internal donor. The catalysts differed by an order of magnitude and more in the content of titanium and donor, activity, specific surface area and pore size. Sizes of MgCl2 crystallites with 110 or 104 lateral cuts were calculated from the Ti/Mg and DPK/Mg values. For highly active TMCs the composition, XRD and specific surface area were in agreement with the MgCl2 crystallites with 104 lateral cuts, TiCl4 adsorption on one magnesium ion and elongated in the 001 direction. For low-activity TMCs obtained by reacting Mg with BuCl, the sizes of MgCl2 crystallites in different directions were close. Activity of the catalysts was inversely proportional to the crystallite size calculated from the TMC composition. This dependence was preserved for the catalysts obtained via the substitution of ketone by phthalate.

Gas-phase C?C coupling reactions mediated by Ni (II) complexes were studied using a linear quadrupole ion trap mass spectrometer. Ternary nickel cationic carboxylate complexes, [(phen)Ni (OOCR1)](+) (where phen = 1,10-phenanthroline), were formed by electrospray ionization. Upon collision-induced dissociation (CID), they extrude CO2 forming the organometallic cation [(phen)Ni(R-1)](+), which undergoes gas-phase ion-molecule reactions (IMR) with acetate esters CH3COOR2 to yield the acetate complex [(phen)Ni (OOCCH3)](+) and a C?C coupling product R-1-R-2. These Ni(II)/phenanthroline-mediated coupling reactions can be performed with a variety of carbon substituents R-1 and R-2 (sp(3), sp(2), or aromatic), some of them functionalized. Reaction rates do not seem to be strongly dependent on the nature of the substituents, as sp(3)-sp(3) or sp(2)-sp(2) coupling reactions proceed rapidly. Experimental results are supported by density functional theory calculations, which provide insights into the energetics associated with the C?C bond coupling step.
