Published: March 2016

ABSTRACTDevelopment of structure–properties relationships between the fillers/rubber matrix interface chemistry and the dispersion and interfacial adhesion properties of the rubber composites is critical to predict their bulk mechanical and tribological properties. In this paper, three solution styrene butadiene rubber (SSBR) composites containing various fillers with tailored interfacial chemistry were prepared via conventional mixing technique. Subsequently, thermal and structural features of filled SSBR composites were monitored by TG, DSC, XRD, XPS, FESEM and TEM, respectively. Sliding contact experiments were conducted to study tribological properties of styrene butadiene rubber composites under dry and wet conditions. It was shown that the SSBR filled with silicon dioxide nanoparticles significantly reduced both the friction coefficient and the wear against marble block. On the contrary, it exhibited an increased friction coefficient and wear under wet friction conditions due to the specific superior wet‐skid resistance of silicon dioxide nanopartilce filled rubber composites, a good dispersion of silicon dioxide nanopartilce in the rubber matrix and strong interfacial adhesion between nanoparticles and rubber matrix. In addition, the influence of fillers dispersion and interfacial adhesion on friction and wear of styrene butadiene rubber composites was evaluated employing theoretical calculation, and the predicted results were in agreement with the experimental observations. © 2016 Wiley Periodicals, Inc.

Published: March 2016

ABSTRACTIn order to further decrease the cost and enhance the durability of sulfonated poly(ether ether ketone) membrane for vanadium redox flow battery, a super thin (40 μm) polytetrafluoroethylene (PTFE)/SPEEK (PS) membrane is prepared. The physico‐chemical properties and single cell performance of PS membranes prepared with different casting solvents including NMP (N‐methyl‐2‐pyrrolidone), DMF (N,N′‐dimethylformamide), and DMAc (N,N′‐dimethylacetamide) have been investigated. Results show that the energy efficiency of VRB with PS/DMF can reach up to 91.2% at the current density of 40 mA cm−2, which is 11.1% and 6.4% higher than that of the commercial Nafion 212 and pristine SPEEK membrane, respectively. In addition, charge–discharge test over 150 times proves that the PS/DMF membrane possesses high stability and thus it is suitable for VRB application. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

Gold nanoparticle layers from multi‐step adsorption immobilised on a polymer surface during injection molding

Published: March 2016

ABSTRACTFunctional nanoparticles exhibit, e.g., a chemical functionality. For their use, a reliable immobilisation is often required. Here, a method is described, how those nanoparticles can be immobilised on a thermoplastic surface using melt processing. Gold nanoparticles (AuNP) are assembled in a layer on a substrate by adsorption. The degree of coverage can be controlled by repeating the adsorption process. During each adsorption step, the particles were arranged on the surface as chain‐like aggregates with close particle–particle contacts, rather than as isolated particles. The degree of area coverage on the substrate surface was up to 70%. The AuNP layers were transferred onto the surfaces of polycarbonate (PC) sheets by injection molding. The AuNP were partly embedded by the thermoplastic polymer and in this way permanently immobilised on the part surface. The reduction of methyl orange demonstrated the accessibility of the gold surface for small molecules. Furthermore, the fabrication of bactericide surfaces, sensor surfaces, all using AuNP immobilised on a thermoplastic part surface may become possible. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

Determining the geochemical variability of fine‐grained basalt sources/quarries for facilitating prehistoric interaction studies in Polynesia

Published: March 2016

ABSTRACTPolynesian adze sourcing studies that rely on geochemical analyses to assign distant artefacts to a source or quarry have been undertaken for more than three decades. Understanding intra‐source geochemical variability is essential for robust artefact source assignments, yet these data are not available for most quarries. We provide a seven‐step protocol for sampling source rocks and associated artefacts at quarries and, using the large Eiao quarry (Marquesas Islands) as a case study, demonstrate the efficacy of the protocol. A “sampling to redundancy” statistical procedure documents that ∼7–11 samples are required to capture the variability of 10 oxides, 49 trace elements and seven isotope ratios. We advocate using the broadest array of fully quantitative geochemical values to characterise quarries and sources that will facilitate current and future sourcing studies. In the biological sense, this is analogous to the formal description of a holotype. Quarry samples should also be collected and curated to enable research when new protocols are established and more precise and accurate geochemical techniques develop.
Enhancing team collaboration through integrating social interactions in a Web‐based development environment

Published: March 2016

ABSTRACTThis paper presents the design and evaluation of a Web‐based collaborative learning environment called EduCo for learning and practicing team‐based exercises in computer science and software engineering courses. EduCo's defining characteristic is integrating a number of services for software development activities, for example, project management, requirements engineering, design, and programming into integrated shared workspaces with social‐networking facilities to enhance collaboration among students and instructors. We conducted a controlled experiment to evaluate the effectiveness of the system in doing a three‐iteration programming project. A total of 126 second‐year students who attended an object‐oriented programming course participated in the experiment. The results show that while the system was not found to affect student programming performance, it improved student engagement and satisfaction when working in teams. These results imply that the system's shared workspaces and social‐networking services have the potential to enhance learning outcomes of students working in teams when these features are integrated into collaborative learning environments. © 2016 Wiley Periodicals, Inc.

A Water‐Soluble Tetraazaperopyrene Dye as Strong G‐Quadruplex DNA Binder
Authors: Hahn Lena , Buurma Niklaas J. , Gade Lutz H. 
Published: March 2016

AbstractThe interactions of the water‐soluble tetraazaperopyrene dye 1 with ct‐DNA, duplex‐[(dAdT)12⋅(dAdT)12], duplex‐[(dGdC)12⋅(dGdC)12] as well as with two G‐quadruplex‐forming sequences, namely the human telomeric 22AG and the promotor sequence c‐myc, were investigated by means of UV/visible and fluorescence spectroscopy, isothermal titration calorimetry (ITC) and molecular docking studies. Dye 1 exhibits a high affinity for G‐quadruplex structures over duplex DNA structures. Furthermore, the ligand shows promising G‐quadruplex discrimination, with an affinity towards c‐myc of 2×107 m−1 (i.e., Kd=50 nm), which is higher than for 22AG (4×106 m−1). The ITC data reveal that compound 1 interacts with c‐myc in a stoichiometric ratio of 1:1 but also indicate the presence of two identical lower affinity secondary binding sites per quadruplex. In 22AG, there are two high affinity binding sites per quadruplex, that is, one on each side, with a further four weaker binding sites. For both quadruplex structures, the high affinity interactions between compound 1 and the quadruplex‐forming nucleic acid structures are weakly endothermic. Molecular docking studies suggest an end‐stacking binding mode for compound 1 interacting with quadruplex structures, and a higher affinity for the parallel conformation of c‐myc than for the mixed‐hybrid conformation of 22AG. In addition, docking studies also suggest that the reduced affinity for duplex DNA structures is due to the non‐viability of an intercalative binding mode.
