The trapping process in polymer systems constitutes a fundamental mechanism for various other dynamical processes taking place in these systems. In this paper, we study the trapping problem in two representative polymer networks, Cayley trees and Vicsek fractals, which separately model dendrimers and regular hyperbranched polymers. Our goal is to explore the impact of trap location on the effic...

Polymer-based ion exchange membranes (IEMs) are utilized for many applications such as in water desalination, energy storage, fuel cells and electrophoretic drug delivery devices, exemplified by the organic electronic pump (OEIP). The bulk of current research is primarily focused on finding highly conductive stable IEM materials. Even though great progress has been made, a lack fundamental unde...

An efficient heavy metal absorbent, amino-terminated hyperbranched polymer modified walnut shell (FWNS) was prepared. The adsorption behavior for Pb(II) ions from aqueous solution also discussed. FWNS prepared using an (ATHBP) as modifying agent and glycidyl methacrylate(GMA) the grafting bridge. characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) Scanning e...

Lead chalcogenide nanostructures are good potential candidates for applications in multiexciton solar cells, infrared photodetectors, and electroluminescence devices. Here we report the synthesis and electrical measurements of hyperbranched PbSe nanowire networks. Hyperbranched PbSe nanowire networks are synthesized via a vapor-liquid-solid (VLS) mechanism. The branching is induced by continuou...

Ionic liquids (IL) and hyperbranched polymers (HyP) represent new classes of nonvolatile selective solvents. By measuring vapor-liquid equilibria (VLE) of azeotropic and close boiling systems in the presence of ionic liquids or hyperbranched polymers, separation factors are derived and the potential of using IL and HyP as entrainer for extractive distillation is discussed. Exemplarily, the supe...

Nanofibrillar micellar structures formed by the amphiphilic hyperbranched molecules within a Langmuir monolayer were utilized as matter for silver nanoparticle formation from the ion-containing water subphase. We observed that silver nanoparticles were formed within the multifunctional amphiphilic hyperbranched molecules. The diameter of nanoparticles varied from 2-4 nm and was controlled by th...
