A green synthesis of silver nanoparticles (AgNPs) using aqueous Lonicera japonica leaf extract (AgNPs-LLJ) was reported and their anti-inflammatory and antibacterial effects were investigated. In comparison, AgNPs were also synthesised using the liquid phase chemical reduction method (AgNPs-N2H4·H2O). The synthesised AgNPs were identified using multiple analytical techniques. The results showed that both AgNPs were spherical particles with an average particle size of 20-30 nm for AgNPs-LLJ and 10-20 nm for AgNPs-N2H4·H2O. The anti-inflammatory ability of AgNPs was shown by the effective inhibition against 5-lipoxygenase with IC50 values of 5.08 µg/mL for AgNPs-LLJ and 59.12 µg/mL for AgNPs-N2H4·H2O, indicating that AgNPs-LLJ had much more obvious antiinflammatory effect. Furthermore, the cytotoxicity research on RAW264.7 mouse macrophages showed that AgNPs-LLJ had no cytotoxicity at the concentration of 40 µg/mL compared with control. Their antibacterial effects on Escherichia coli (EC) and Staphlococcus aureus (SA) were studied by agar well diffusion method. The maximum antibacterial circles of AgNPs-N2H4·H2O on EC and SA were 15 and 14 mm, respectively, whereas it was 5.0 and 5.0 mm for AgNPs-LLJ, respectively. The authors conclude that AgNPs-LLJs have a potential to be a nanomedicine for nanobiomedical applications. [ABSTRACT FROM AUTHOR]

By using a newhybridmethod, a strong convergence theorem for finding a common element of the set of solutions of an equilibrium problem and the set of fixed points of Bregman strongly nonexpansive mappings in a reflexive Banach space is proved. [ABSTRACT FROM AUTHOR]

The purpose of this paper is first to introduce the concept of total quasi-ɸ-asymptotically nonexpansive mapping which contains many kinds of mappings as its special cases and then to use a hybrid algorithm to introduce a new iterative scheme for finding a common element of the set of solutions for a system of generalized mixed equilibrium problems and the set of common fixed points for a countable family of total quasi-ɸ-asymptotically nonexpansive mappings. Under suitable conditions some strong convergence theorems are established in an uniformly smooth and strictly convex Banach space with Kadec-Klee property. The results presented in the paper improve and extend some recent results. [ABSTRACT FROM AUTHOR]

The purpose of this paper is to use a new hybrid algorithm for finding a common element of the set of solutions for a system of generalized mixed equilibrium problems and the set of common fixed points for an infinite family of quasi-φ-asymptotically nonexpansive mappings.

The purpose of this paper is, by using a new hybrid method, to prove a strong convergence theorem for finding a common element of the set of solutions for a generalized mixed equilibrium problem, the set of solutions for a variational inequality problem, and the set of common fixed points for a pair of quasi-φ-asymptotically nonexpansive mappings. Under suitable conditions some strong convergence theorems are established in a uniformly smooth and strictly convex Banach space with Kadec-Klee property. The results presented in the paper improve and extend some recent results. [ABSTRACT FROM AUTHOR]

The article studies a heterogeneous kinetic model of the oxidative polymerization of 2,6-dimethylphenol (DMP) with a copper-ethylenediaminetetraacetic acid (EDTA) complex in water. It examines the influence of DMP concentration and reaction temperature on the oxidative polymerization rate. It considers catalyst deactivation and the difference in reactivity between the monomer, water-soluble oligomer and water-soluble oligomer in the kinetic model. The study uses nonlinear regression analysis to present an estimate of the values of kinetic parameters.

The changes of the molecular weight and particle size with time during the oxidative polymerization of 2,6‐dimethylphenol in an aqueous medium were studied. At the beginning of the oxidative polymerization, the oligomers with the hydrophilic phenoxy anion at the end of oligomer chains are formed rapidly in the aqueous medium. When the molecular weight of the oligomer reaches up to a critical value, the oligomer precipitates out from the water, resulting in the formation of the original particle (or domain). With the increase of the molecular weight, the concentration of the phenoxy anion and the surface charge density of the original particles decrease; therefore, the repulsion force between original particles weaken and the stability of particles in water decreases, resulting in the coagulation of the original particle and the formation of the primary particle. With the further progression of the polymerization, the primary particles coagulate and final particles are formed. A three‐stage mechanism of the particle formation is proposed, that is, the particle nucleation, first coagulation, and second coagulation. © 2007 Wiley Periodicals, Inc.
