Thiol-functionalized PIM-1 for removal and sensing for mercury (II)

Polymers of intrinsic microporosity (PIMs) are a class of microporous polymers with rigid and contorted molecular structures. The special structures lead to incomplete space occupation, and the pores of PIMs originate from the formed void. In this work, we made attempts to expand the applications of PIMs to the aspect of heavy metal removal. First, PIM-1 was synthesized using tetrafluoroterephthalonitrile (TFTPN) and 5,5′,6,6′-tetrahydroxy-3,3,3′,3′-tetramethyl-1,1′-spirobisindane (TTSBI) as precursors. The primary PIM-1 was quite hydrophobic, and thus could not be evenly dispersed in water, resulting in low adsorption capacity for mercury ions (Hg2+). A conversion of nitrile group in PIM-1 to thiol group was then carried out by two steps, namely carboxylation and introduction of thiol groups. The carboxylation made the polymers more active, and the final thiol-functionalization provided the polymers with hydrophilicity and affinity for Hg2+. The thiolethyl modified PIM-1 (assigned as PIM-G) and thiophenyl modified (assigned as PIM-B) possessed maximum Hg2+ adsorption capacity of 136 mg g(-1) and 127 mg g(-1) at pH 5, respectively. Besides, the thiol-functionalized PIMs had fluorescence property and showed potential in sensing for Hg2+.

Oxalato bridged coordination polymer of manganese(iii) involving unconventional OMIDLINE HORIZONTAL ELLIPSIS pi-hole(nitrile) and antiparallel nitrileMIDLINE HORIZONTAL ELLIPSISnitrile contacts: antiproliferative evaluation and theoretical studies

A new oxalato bridged polymeric Mn(iii) coordination compound, {[Mn-2(eta(2)-C2O4)(H2O)(2)Cl-4] 2(4-CNpy)}(n) (1) (C2O4 = oxalate, 4-CNpy = 4-cyanopyridine), has been synthesized and characterized using elemental analysis, and spectroscopic (IR, electronic, XPS) and single crystal X-ray diffraction techniques. Electronic and XPS analyses of the compound justify the presence of a Mn(iii) center that is charge compensated by the two chlorido ligands and the oxygen atom of the bridged oxalate. 4-CNpy molecules in the lattice form unconventional H-bonded supramolecular dimers in the solid state assisted by antiparallel CNMIDLINE HORIZONTAL ELLIPSISCN dipoleMIDLINE HORIZONTAL ELLIPSISdipole interactions, which has been confirmed using QTAIM and NCI plot analysis and supported by MEP surface analysis. Remarkably, this dimer concurrently establishes a weak anion-pi interaction with the coordinated chlorido ligand. Unexpectedly, QTAIM analysis reveals the existence of an interesting OMIDLINE HORIZONTAL ELLIPSIS pi-hole(nitrile) contact involving the coordinated water molecule and the nitrile moiety that also contributes to the stabilization of the dimer in the crystal structure. To the best of our knowledge, the existence of such pi-hole interaction involving nitrile derivatives has not been reported before. Compound 1 has been further screened for anticancer activity in the malignant Dalton’s lymphoma (DL) cell line and the results were confirmed by molecular docking and pharmacophore features. Our findings indicated that the cytotoxicity of compound 1 is initially increased in a dose dependent manner (0.01-1 mu M) and then decreased (5-10 mu M), which is also affected by the reactive oxygen species (ROS) in the cells. Interestingly, very low cytotoxicity (5-14%) was observed in the case of healthy cells (PBMC) for similar experimental conditions.

Mechanistic Vistas of Trivalent Nitrogen Compound Reduction by Samarium Diiodide

In trivalent nitrogen compounds, the nitrogen lone pair is highly amenable to bind to samarium iodide prior to electron transfer. As SmI2 is more azaphilic than oxophilic, its affinity to the nitrogen lone pair is more pronounced in aza substrates than in the analogous carbonyl compounds. The impact of this binding is very large in terms of reaction rate and at the same time gives rise to unique mechanistic phenomena, which include unusual kinetic rate orders, catalysis by quantum dots, and remote functionalization. Even reduction of nitriles was found to be affected by this coordination to SmI2. This review focuses on the reduction mechanisms of three groups of compounds: imines, azobenzene, and nitriles.

Mullins Effect and Its Reversibility for Thermoplastic Vulcanizates Based on Ethylene-Acrylic Acid Copolymer/Nitrile-Butadiene Rubber Blends

Mullins effect during uniaxial cyclic compression tests, together with its reversibility, of ethylene-acrylic acid copolymer (EAA)/nitrile-butadiene rubber (NBR) thermoplastic vulcanizates (TPVs) were investigated systematically. The results showed that EAA/NBR TPVs had excellent mechanical properties when the weight ratio was 40/60. Morphology studies showed that sphere-like NBR particles were dispersed evenly in the etched TPVs surface with diameters of 5-8 mu m. The experimental results of Mullins effect indicated that a stress softening phenomenon in the stress-strain curves of EAA/NBR TPVs during the uniaxial loading-unloading cycles could be observed obviously; moreover, the reversibility of Mullins effect could be significantly enhanced by increasing heat treatment temperature.

Cu-catalyzed cyanomethylation of imines and alpha,beta-alkenes with acetonitrile and its derivatives

We describe copper-catalyzed cyanomethylation of imines and alpha,beta-alkenes with a methylnitrile source and provide an efficient route to synthesize arylacrylonitriles and beta,gamma-unsaturated nitriles. This method tolerates aliphatic and aromatic alkenes substituted with a variety of functional groups such as F, Cl, Br, Me, OMe, tert-Bu, NO2, NH2 and CO2H with good to excellent yields (69-98%). These systems consist of inexpensive, simple copper catalyst and acetonitrile with its derivatives (alpha-bromo/alpha-iodo-acetonitrile) and are highly applicable in the industrial production of acrylonitriles.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 103146-25-4. HPLC of Formula: C20H23FN2O2.

Development of a Drone-Based Thin-Film Solid-Phase Microextraction Water Sampler to Facilitate On-Site Screening of Environmental Pollutants

To simplify on-site water sampling and screening, particularly in hard-to-reach or dangerous sites, a drone equipped with a hydrophilic-lipophilic balance (HLB), thin-film solid-phase microextraction (TF-SPME) sampler was developed. The drone-based sampler was shown to protect the sorbent phase from external contamination while preventing any detectable loss of components of a spiked modified McReynolds mixture on the membrane in the sampler for at least 10 min. HLB/poly(dimethylsiloxane) (PDMS) membranes deployed in flight on the drone sampler were demonstrated to extract disinfection by-products, including trichloromethane, dichloroacetonitrile, 1,1,1-trichloro-2-propanone, 2,2,2-trichloroethanol, benzonitrile, and benzyl nitrile, from hot tub water. When analyzed on-site, in duplicate, using hand-portable instrumentation, reasonably repeatable results were achieved (%relative standard deviations (RSD’s) 5-16%). Finally, drone TF-SPME sampling of an anthropogenically impacted watercourse indicated that impact from the suspected nearby landfill site was minimal, instead suggesting that internal combustion by-products from vehicles on the nearby Highway 401 played a much larger role in contaminating the watercourse. This conclusion was supported by the confirmed presence of BTEX, styrene, isopropylbenzene, propylbenzene, and 1,3,5-trimethylbenzene. In addition to immediately identifying these compounds on-site using portable gas chromatography-mass spectrometry (GC-MS), samples were taken back to the laboratory for benchtop analysis, further supporting this conclusion.

Nitrile hydratase mediated green synthesis of lactamide by immobilizing Rhodococcus pyridinivorans NIT-36 cells on N, N ‘-Methylene bis-acrylamide activated chitosan

In this paper green synthesis of an important commodity chemical lactamide has been undertaken using chitosan immobilized Rhodococcus pyridinivorans NIT-36 harbouring nitrile hydratase (NHase) enzyme. The cells immobilization (300 mg/g) is based on the partial entrapment of cells by suspension cross-linking technique facilitated by N, N’-Methylene bis-acrylamide. In the repeated-use experiments, the immobilized cells retained 80% of its initial activity when stored at 4 degrees C for 30 days. NHase activity of free and immobilized cells was studied over temperature ranging from 25 degrees C to 60 degrees C. The activity for free cells showed a sharp decline of 70% when the reaction temperature was elevated from 45 degrees C to 50 degrees C whereas chitosan immobilized cells retained their activity in the same temperature range. A fed-batch reaction was designed and the immobilized cells showed 100% similar enzymatic pattern for five consecutive rounds which gradually decreased in following cycles. A volumetric productivity of 20 g/L and catalytic productivity of 8.33 g/g dcw/h for lactamide were achieved. (C) 2020 Elsevier B.V. All rights reserved.

Strain Rate Dependent Behavior of Vinyl Nitrile Helmet Foam in Compression and Combined Compression and Shear

Featured Application Results of this work can be used to compare VN foams to other helmet liner materials and could help in the design of new protective devices. Vinyl nitrile foams are polymeric closed-cell foam commonly used for energy absorption in helmets. However, their impact behavior has never been described in isolation. This study aims to characterize the strain rate dependent behavior of three VN foams in compression and combined compression and shear. Vinyl nitrile samples of density 97.5, 125, and 183 kg/m(3) were submitted to quasi-static compression (0.01 s(-1)) and impacts in compression and combined compression and shear (loading direction of 45 degrees). For impacts, a drop test rig was used, and a method was developed to account for strain rate variation during impactor deceleration. Young’s modulus and stress at plateau were correlated with foam density in both compression and combined loading. Vinyl nitrile foams were strain rate dependent: The absorbed energy at the onset of densification was two to four times higher at 100 s(-1) than at 0.01 s(-1). In combined loading, the compressive stress at yield was reduced by 43% at a high strain rate. Compared to expanded polypropylene, vinyl nitrile foams transmitted less stress at the onset of densification for equivalent absorbed energy and presented a larger ratio between the compression and shear stresses in combined loading (0.37 at yield). This larger ratio between the compression and shear stresses might explain why vinyl nitrile helmet liners are thought to be better at reducing head rotational acceleration than expanded polypropylene helmet liners.
