Blue-shifted emission and enhanced quantum efficiency via [small pi]-bridge elongation in carbazole-carborane dyads

25-May-2016 | Zhaojin Wang; Peng Jiang; Tianyu Wang; Graeme Moxey; Marie Cifuentes; Chi Zhang; Mark G Humphrey, Physical Chemistry Chemical Physics, 2016

Carbazole-carborane linear dyads and di(carbazole)-carborane V-shaped dyads with phenyleneethynylene-based bridges have been synthesized. The V-shaped dyads display the expected red-shifts in the location of their UV-Vis absorption maxima on bridge-lengthening, but show unusual blue-shifts in ...

Polyisobutylene‐based polyurethanes X: PU nanocomposites with s‐containing soft segments

21-May-2016 | Nihan Nugay, Kalman Toth, Nur Cicek Kekec, Turgut Nugay, Joseph P. Kennedy, Journal of Polymer Science Part A: Polymer Chemistry, 2016

ABSTRACT Sulfur‐containing polyisobutylene (PIB)‐based polyurethane nanocomposite (PIBs‐PU/NC) was synthesized using HOCH2CH2SPIBSCH2CH2OH for the soft segment, conventional hard segments of MDI and BDO, and organically modified montmorillonite (OmMMT) nanolayers. The properties of ...

[Report] Accelerated actin filament polymerization from microtubule plus ends

20-May-2016 | Jessica L. Henty-Ridilla; Aneliya Rankova; Julian A. Eskin; Katelyn Kenny; Bruce L. Goode, Science , 2016

Microtubules (MTs) govern actin network remodeling in a wide range of biological processes, yet the mechanisms underlying this cytoskeletal cross-talk have remained obscure. We used single-molecule fluorescence microscopy to show that the MT plus-end–associated protein CLIP-170 binds tightly to ...

Preparation of high toughness and high transparency polylactide blends resin based on multiarmed polycaprolactone‐block‐poly(l‐lactide)

19-May-2016 | Xinchao Bian, Bao Zhang, Bin Sun, Zhiqiang Sun, Sheng Xiang, Gao Li, Xuesi Chen, Polymer Engineering and Science, 2016

Modification of poly(l‐lactide) (PLLA) via blending with two or more polymers is one of the effective approaches used to overcome the brittleness of PLLA, which often requires the addition of a compatibilizer and generate opaque materials. To solve this problem, multiarmed ...

Recycling of wood fiber‐reinforced HDPE by multiple reprocessing

19-May-2016 | Dan Åkesson, Torsten Fuchs, Michael Stöss, Andrew Root, Erik Stenvall, Mikael Skrifvars, Journal of Applied Polymer Science, 2016

ABSTRACT The mechanical recycling of high‐density polyethylene (HDPE) reinforced with wood fiber was studied by means of repeated injection moulding. The change in properties during the recycling was monitored by tensile and flexural tests, Charpy impact tests, differential scanning ...

General model for comparative tensile mechanical properties of composites fabricated from fly ash and virgin/recycled high‐density polyethylene

19-May-2016 | Imrana I. Kabir, Charles C. Sorrell, Mykanth R. Mada, Sagar T. Cholake, Sri Bandyopadhyay, Polymer Engineering and Science, 2016

The present work on the mechanical properties of ≤10 wt% fly ash additions in 2.5 wt% increments to recycled high‐density polyethylene (RHDPE) synthesizes experimental data from three similar published reports. The present work shows, as a function of increasing fly ash addition level, maxima at ...

Tensile behavior of polyolefin composites: the effect of matrix parameters

19-May-2016 | Maria Guseva, Victor Gerasin, Boris Shklyaruk, Journal of Applied Polymer Science, 2016

ABSTRACT Polyolefin composites were prepared from 14 PE matrices and three different mineral fillers (montmorillonite, palygorskite and glass microspheres) via melt compounding in an extruder. Mechanical properties of the obtained systems were analyzed with emphasis on elongation at break and ...

Tofu Whey Permeate Is an Efficient Source To Enzymatically Produce Prebiotic Fructooligosaccharides and Novel Fructosylated α-Galactosides

18-May-2016 | Marta Corzo-Martínez; Gema García-Campos; Antonia Montilla; F. Javier Moreno, Journal of Agricultural and Food Chemistry, 2016

This work addresses a novel and efficient bioconversion method for the utilization of tofu whey permeate (TWP), an important byproduct from the soybean industry, as a precursor of high value-added ingredients such as prebiotic fructooligosaccharides and novel fructosylated α-galactosides. This ...

Selectivity of Pyridone- and Diphenyl Ether-Based Inhibitors for the Yersinia pestis FabV Enoyl-ACP Reductase

17-May-2016 | Carla Neckles; Annica Pschibul; Cheng-Tsung Lai; Maria Hirschbeck; Jochen Kuper; Shabnam Davoodi; Junjie Zou; Nina L ..., Biochemistry, 2016

The enoyl-ACP reductase (ENR) catalyzes the last reaction in the elongation cycle of the bacterial type II fatty acid biosynthesis (FAS-II) pathway. While the FabI ENR is a well-validated drug target in organisms such as Mycobacterium tuberculosis and Staphylococcus aureus, alternate ENR isoforms ...

Microstructural characterization of short glass fibre reinforced polyethersulfone composites

13-May-2016 | L. M. Munirathnamma, H. B. Ravikumar, Journal of Applied Polymer Science, 2016

ABSTRACT To explore the effect of short glass fiber reinforcement (SGFR) on the mechanical properties of polyethersulfone (PES), microstructural characterization has been performed by positron lifetime technique. The free volume distribution of SGFR‐PES composites derived from CONTIN‐PALS2 ...
