V.; Kozitsina, Alisa N. published the artcile< A label-free impedimetric immunosensor based on covalent immobilization of anti-E. Coli antibody via a copper-catalyzed azide-alkyne cycloaddition reaction>, COA of Formula: C9H9Cl, the main research area is impedimetry immunosensor antibody immobilization; Antibody covalent immobilization; Copper-catalyzed azide-alkyne cycloaddition; E. coli; Label-free impedimetric immunosensor.

An original method is proposed for address and covalent immobilization of anti-E. coli antibodies on a screen-printed electrode (SPE). The method is based on a copper-catalyzed “”click”” reaction between a polyvinylbenzylazide (PVBA) film electrochem. deposited on the electrode surface and acetylene fragments of propargyl-N-hydroxysuccinimide ester. The products of electrochem. oxidation of copper particles incorporated in the polymer film on the electrode were first used for catalysis of the click reaction. This approach allowed the authors to reduce the immobilization time from a few hours for conventional methods to just 30 min, and to prevent denaturation of the immunoreceptor. The modified electrodes were characterized by SEM, electrochem. impedance spectroscopy (EIS), and cyclic voltammetry (CV). Based on the results obtained, a label-free impedimetric immunosensor for E. coli detection was developed. The detection limit of the immunosensor was estimated as 6.3 CFU/mL, with a linear range of 103-106 CFU/mL. The immunosensor demonstrated good stability during 30 days of storage in phosphate buffer solution (PBS, pH 7) and selectivity toward excess Staphylococcus aureus bacteria.

Capparelli, Clara; Fernandez Pulido, Carlos R.; Lopez-Hallman, Raymond; Geise, Geoffrey M.; Hickner, Michael A. published the artcile< Anion Exchange Membranes with Dynamic Redox-Responsive Properties>, Application of C9H9Cl, the main research area is anion exchange membrane dynamic redox; anion exchange membranes; redox-responsive membranes; stimuli-responsive membranes; transport properties; viologen.

Redox-responsive anion exchange membranes were developed using photoinitiated free-radical polymerization and reversible oxidation and reduction of viologen. The membranes were formulated using poly(ethylene glycol diacrylate) and diurethane dimethacrylate oligomers, dipentaerythritol penta-/hexa-acrylate cross-linker, photoinitiators, and 4-vinylbenzyl chloride as precursors for functionalization. In the membrane, 4,4′-bipyridine reacted with the 4-vinylbenzyl chloride residues, and subsequently, unreacted amines were methylated with iodomethane to obtain viologen as both the ion carrier and redox-responsive group. Upon oxidation, viologen supports two cations, where the reduced form only contains one cation. Thus, the redox responsiveness changed the membrane ionicity by a factor of 2. The area-specific resistance of the membranes in the oxidized, +2, state was lower than in the reduced, +1, state. The resistance increased between 40.6 ± 0.1 and 111.6 ± 0.1%, depending on membrane thickness, with the most significant increment being a resistance change from 4.88 × 10-4 Ω m2 in the oxidized state to 1.03 × 10-3 Ω m2 in the reduced state. Membrane permselectivity in the reduced, +1, state was between 15.9 ± 0.1 and 26.5 ± 0.01% lower than in the oxidized, +2, state, with no change in water uptake, spanning an average of 0.87 ± 0.02 in the oxidized state to an average of 0.7 ± 0.01 in the reduced state. Upon reduction, membrane ion-exchange capacity decreases, increasing ionic resistance and decreasing membrane permselectivity due to a reduction in fixed charge concentration without a measurable change in water uptake. This trend is not generally observed for ion-exchange membranes and explains that the changes in transport properties result from changes in ionicity, not water uptake or domain size. The reversibility and stability of the stimuli responsiveness were confirmed by the absence of transport property changes after redox cycling.

The macroporous microspheres with core-shell structure, based on a copolymer of 4-Vinylbenzyl chloride, glycidyl methacrylate, and ethylene glycol dimethacrylate, were fabricated through atom transfer radical polymerization suspension polymerization The microspheres showed 100-200 nm pores in shell and 500-900 nm pores in core. The shell was hydrophilic modified through grafting of poly(N-hydroxyethyl acrylamide) onto the shell surface for reducing adsorption of proteins. The core was coupled with a ligand of poly(ethylene imine) that could bind the proteins. Feedstock of avian influenza virus could be purified on these modified microspheres through neg. chromatog. Avian influenza virus cannot enter the core and was recovered from the flow-through, while other proteins with neg. charges were able to penetrate into the core and bind to the poly(ethylene imine) ligands. The dynamic binding capacity of proteins was higher on this medium (61 mg/mL) than the com. available resin (12 mg/mL, Capto Core 700).

Hoffmann, Maxi; Iacob, Ciprian; Kaysan, Gina; Simmler, Mira; Nirschl, Hermann; Guthausen, Gisela; Wilhelm, Manfred published the artcile< Charge Transport and Glassy Dynamics in Blends Based on 1-Butyl-3-vinylbenzylimidazolium Bis(trifluoromethanesulfonyl)imide Ionic Liquid and the Corresponding Polymer>, Recommanded Product: 1-(Chloromethyl)-4-vinylbenzene, the main research area is butyl vinylbenzylimidazolium bistrifluoromethanesulfonyl imide ionic liquid polymer glassy dynamic; PFG-NMR; broadband dielectric spectroscopy; charge transport; imidazolium; ionic liquid blends; ionic liquids; rheology.

Charge transport, diffusion properties, and glassy dynamics of blends of imidazolium-based ionic liquid (IL) and the corresponding polymer (polyIL) were examined by Pulsed-Field-Gradient NMR (PFG-NMR) and rheol. coupled with broadband dielec. spectroscopy (rheo-BDS). We found that the mech. storage modulus (G’) increases with an increasing amount of polyIL and G’ is a factor of 10,000 higher for the polyIL compared to the monomer (GIL’ = 7.5 Pa at 100 rad s-1 and 298 K). Furthermore, the ionic conductivity (σ0) of the IL is a factor 1000 higher than its value for the polymerized monomer with 3.4×10-4 S cm-1 at 298 K. Addnl., we found the Haven Ratio (HR) obtained through PFG-NMR and BDS measurements to be constant around a value of 1.4 for the IL and blends with 30 weight% and 70 weight% polyIL. These results show that blending of the components does not have a strong impact on the charge transport compared to the charge transport in the pure IL at room temperature, but blending results in substantial modifications of the mech. properties. Furthermore, it is highlighted that the increase in σ0 might be attributed to the addition of a more mobile phase, which also possibly reduces ion-ion correlations in the polyIL.

Rising atm. CO2 levels and water pollution have necessitated new research towards the development of novel CO2 capture materials and innovative methods for wastewater treatment. Herein, we demonstrate a facile fabrication strategy to prepare novel template-shape-replicated nitrogen-rich mesoporous carbon nanospheres (NMCN) with high surface area, pore volume and ordered pore geometry via a combination of in situ co-condensation, surface-confined atom transfer radical polymerization (SC-ATRP) and post-polymerization modification. NMCN exhibited efficient CO2 capture performance and contaminant removal capability from wastewater. This work may open a new direction for the design of novel porous nanomaterials for CO2 capture and other emerging applications.

Nitration-peroxidation of alkenes for the synthesis of β-peroxyl nitroalkanes has been developed by using tert-Bu nitrite and tert-Bu hydroperoxide. The method presents a new and selective difunctionalization of alkenes to introduce a nitro group and a peroxyl group across the double bonds of alkenes under mild conditions. A radical reaction pathway is proposed by exptl. and theor. studies. Of note, mixing a metal salt and peroxide can cause an explosion.

Ju, Changha; Park, Chanhyuk; Kim, Taehyung; Kang, Hyo published the artcile< Vertical alignment of liquid crystals on plant-based vanillin derivative-substituted polystyrene films>, Formula: C9H9Cl, the main research area is vanillin polystyrene film liquid crystal thermal optical property.

To investigate the alignment behavior of liquid crystal (LC) mols., we synthesized a series of vanillin derivative-substituted polystyrene films (PVAN#, # = 20, 40, 60, 80, and 100), where # is the substitution ratio (%) of the vanillyl Bu ether (VAN) moiety as one of the bio-renewable vanillin derivatives In general, a vertical LC alignment was observed in the LC cell fabricated using the polymer film having a higher molar content of VAN. Moreover, the surface energies of these polymer films were strongly related to the vertical LC alignment behavior. For example, a uniform vertical alignment was observed when the polar surface energy of the polymer was lower than approx. 2.05 mJ m-2, induced by the nonpolar and long carbon groups in the plant-based vanillin moiety. The LC cell fabricated using PVAN100 had good electrooptical characteristics such as voltage holding ratio and residual direct-current voltage and stable alignment under extreme external conditions.

This manuscript describes the structure-property-morphol. relationships of doubly charged 1,4-diazabicyclo[2.2.2]octane (DABCO) salt-containing ABA triblock ionomers. The triblock copolymers consist a soft poly(Bu acrylate) (PnBA) central block and two external styrenic hard blocks bearing amphiphilic pendant C18-alkyl groups and doubly charged salt units. Surprisingly, the DABCO salt-containing ABA block copolymers preserved the thermomech. integrity until degradation, which indicated the formation of a reinforcing phys. network compared to the corresponding doubly charged random copolymers and singly charged block copolymer analogs. Small-angle X-ray scattering data revealed that the DABCO-based ABA block copolymers self-assembled into highly ordered hierarchical microstructures, in which the soft and hard domain of the block copolymers phase-separated into highly ordered lamellar morphologies. Moreover, a secondary structure that originated from the ordering of the amphiphilic pendant groups formed within the lamellar hard domain. The interesting thermal, thermomech., and morphol. properties of doubly charged ionic block copolymers open promising avenues for the synthesis of novel thermoplastic elastomers.

Abbasi, Amin; Nasef, Mohamed Mahmoud; Yahya, Wan Zaireen Nisa; Moniruzzaman, Muhammad; Ghumman, Ali Shaan Manzoor published the artcile< Preparation and characterization of sulfur-vinylbenzyl chloride polymer under optimized reaction conditions using inverse vulcanization>, Category: chlorides-buliding-blocks, the main research area is sulfur vinylbenzyl chloride polymer inverse vulcanization morphol thermal.

Inverse vulcanization offers a new method to make value to this cheap and highly abundant sulfur to produce sulfur-based polymers for different applications. However, most of the research done so far dealt with the characterization of the polymers or their efficiency in certain applications. Here, 4-vinylbenzyl chloride (VBC) is reacted with sulfur under optimized reaction conditions to produce linear sulfur-based polymer. Response Surface Methodol. (RSM) is employed to optimize the reaction conditions in terms of reaction temperature, reaction time, and initial sulfur content. The properties of the polymer produced under optimized conditions are then evaluated using proton NMR (1H NMR), CHNS elemental anal., thermogravimetric anal. (TGA), differential scanning calorimetry (DSC), Fourier transform IR spectroscopy (FTIR), powder X-Ray diffraction (PXRD), and field emission SEM (FESEM). The formation of the polymer and full conversion of the monomers were confirmed by NMR and CHNS anal. The S/VBC polymer showed a uniform morphol. and smooth surface. The polymer demonstrated an amorphous structure with a low Tg (3.7°C), high thermal stability (205°C), and great stability against depolymerization by time. The S/VBC polymer is significant due to its ability for post-functionalization which makes it possible to introduce new applications to sulfur-based polymers.
