Organic Dyes with a Fused Segment Comprising Benzotriazole and Thieno[3,2-b]pyrrole Entities as the Conjugated Spacer for High Performance Dye-Sensitized Solar Cells

07-Oct-2015 | Jen-Shyang Ni; Yi-Chi Yen; Jiann Tseun Lin, Chemical Communication, 2015

Sensitizers with a fused segment comprising electron deficient benzotriazole (BZ) and electron rich thiophene or thieno[3,2-b]pyrrole entities as the conjugated spacer have been synthesized for dye-sensitized solar cells (DSSCs). The power conversion efficiency (PCE) increases with elongation of ...


Waste ceramic dust activated by gamma radiation and coupling agents as reinforcement for nitrile rubber

01-Oct-2015 | Khaled F. El‐Nemr, Mona Y. El‐Naggar, E.S. Fathy, Journal of Vinyl and Additive Technology, 2015

The effect of silicate load in waste ceramic dust on characteristics and performance of acrylonitrile butadiene rubber has been investigated. In order to enhance the interfacial adhesion between the rubber matrix and the filler, the latter was activated with two different types of coupling ...


Kinetic insights into the elongation reaction of actin filaments as a function of temperature, pressure and macromolecular crowding

30-Sep-2015 | Roland Hermann Alfons Winter, Mimi Gao, ChemPhysChem, 2015

Actin polymerization is an essential process in eukaryotic cells to provide driving force for motility and mechanical resistance for cell shape. By using preformed gelsolin‐actin nuclei and applying stopped‐flow methodology, we quantitatively studied the elongation kinetics of actin filaments as ...


Synthesis and Characterization of Fluorinated Polyimide Derived from 3,3′‐Diisopropyl‐4,4′‐diaminodiphenyl‐3′′,4′′‐difluorophenylmethane

29-Sep-2015 | Xiaohua Huang, Mei Mei, Chanjuan Liu, Xianglin Pei, Chun Wei, Chinese Journal of Chemistry, 2015

Abstract A novel aromatic diamine monomer, 3,3′‐diisopropyl‐4,4′‐diaminodiphenyl‐3′′,4′′‐difluorophenylmethane (PAFM), was successfully synthesized by coupling of 2‐isopropylaniline and 3,4‐difluorobenzaldehyde. The aromatic diamine was adopted to synthesize a series of fluorinated polyimides ...


Electron–Proton Decoupling in Excited‐State Hydrogen Atom Transfer in the Gas Phase

29-Sep-2015 | Mitsuhiko Miyazaki, Ryuhei Ohara, Kota Daigoku, Kenro Hashimoto, Jonathan R. Woodward, Claude Dedonder, Christophe J ..., Angewandte Chemie International Edition, 2015

Abstract Hydrogen‐release by photoexcitation, excited‐state‐hydrogen‐transfer (ESHT), is one of the important photochemical processes that occur in aromatic acids and is responsible for photoprotection of biomolecules. The mechanism is described by conversion of the initial state to a ...


Evaluation of environmentally assisted fracture of austempered ductile iron (ADI) under cyclic load bearing

29-Sep-2015 | F Fernández Scudeller, R A Martínez, Fatigue & Fracture of Engineering Materials & Structures, 2015

Abstract This paper aims to characterize the behaviour of austempered ductile iron (ADI) under cyclic load bearing and its surface in contact with water. The first part is devoted to verifying the drop in Ultimate tensile strength and the elongation that takes place when ADI tensile ...


Fabrication of alumina based electrically conductive polymer composites

29-Sep-2015 | QuratulAin Nadeem, Muhammad Rizwan, Rohama Gill, Muhammad Rafique, Muhammad Shahid, Journal of Applied Polymer Science, 2015

ABSTRACT Novel electrically conductive composites were synthesized by incorporating Cu coated alumina (Cu‐Al2O3) powder prepared via electroless plating technique as filler (0–21wt %) into polystyrene‐b‐methylmethacrylate (PS‐b‐PMMA) and polystyrene (PS) matrices. XRD analysis depicted maximum ...


Phase structure and mechanical properties of PP/EPR/CaCO3 nanocomposites: Effect of particle's size and treatment

29-Sep-2015 | Ahmed Elloumi, Sylvie Pimbert, Chedly Bradai, Polymer Engineering and Science, 2015

Calcium carbonate (CaCO3) reinforced polypropylene/ethylene propylene rubber (PP/EPR) copolymer composites for automotive use were developed by means of extrusion and injection molding process. Three kinds of CaCO3 (stearic acid treated and untreated) nanoparticles and microparticles were used ...


Mechanism of dynamic reorientation of cortical microtubules due to mechanical stress

27-Sep-2015 | Author(s): Alexander Muratov, Vladimir A. Baulin, Biophysical Chemistry, 2015

Publication date: Available online 25 September 2015 Source:Biophysical Chemistry Author(s): Alexander Muratov, Vladimir A. Baulin Directional growth caused by gravitropism and corresponding bending of plant cells has been explored since 19th century, however, many aspects of mechanisms ...


Preparation and properties of octadecylamine modified graphene oxide/styrene‐butadiene rubber composites through an improved melt compounding method

26-Sep-2015 | Chunwei Wang, Zijin Liu, Shifeng Wang, Yong Zhang, Journal of Applied Polymer Science, 2015

ABSTRACT Octadecylamine modified graphene oxide/styrene‐butadiene rubber (GO‐ODA/SBR) composites are prepared by a novel and environmental‐friendly method called “Improved melt compounding”. A GO‐ODA/ethanol paste mixture is prepared firstly, and then blended with SBR by melt compounding. ...
