Preparation and characterization of poly(vinylidene fluoride) nanocomposites containing multiwalled carbon nanotubes
Authors: Chen Dan , Wang Min , Zhang Wei‐De , Liu Tianxi
Published: March 2009

Poly(vinylidene fluoride) (PVDF) nanocomposites with different loadings of multiwalled carbon nanotubes (MWNT) were prepared by melt‐compounding technique. A homogeneous dispersion of MWNT throughout PVDF matrix was observed on the cryo‐fractured surfaces by scanning electron microscopy. Thermogravimetric analysis results indicated that the thermal stability of neat PVDF was improved with the incorporation of MWNT. Dynamic mechanical analysis showed a significant improvement in the storage modulus over a temperature range from −125 to 75°C with the addition of MWNT. The melt‐rheological studies illustrated that incorporating MWNT into PVDF matrix resulted in higher complex viscosities (|η*|), storage modulus (G′), loss modulus (G″), and lower loss factor (tan δ) than those of neat PVDF. © 2009 Wiley Periodicals, Inc.

Authors: Wang Z. D. , Li D. F. , Xiong Z. Y. , Chang R. N.
Published: March 2009

The thermomechanical constitutive equations are critical for shape memory polymers (SMPs) in analyzing their shape, memory, and recovery responses under different constraints. In this study, a new physical‐based, temperature and time‐dependent constitutive model was proposed. The deformation mechanisms of this class of functional materials were explained, and the theoretical predicting values by different models were compared with available experimental results. © 2009 Wiley Periodicals, Inc.

Hardness of irradiated hydroxyethyl methacrylate copolymer at elevated temperatures
Authors: Lu K. P. , Fu Y. K. , Lee Sanboh
Published: March 2009

The hardness of irradiated hydroxyethyl methacrylate (HEMA) copolymer at elevated temperatures was measured using a microhardness tester. The hardness increases with annealing time, and is attributed to the defects present in the molecular chains. The defects that control the hardness are related to the entanglement of polymer chain and follow a first order kinetics process. The relaxation time satisfies the Arrhenius equation, with constant activation energy of 25 kJ/mol independent of the irradiation dose. The results were compared with those of PMMA and LiF single crystals reported in the literature. The present findings are useful in the study of soft contact lens, kidney dialysis system, drug delivery system, and artificial liver support system. © 2009 Wiley Periodicals, Inc.

Nanoclay exfoliation in rubber compounds characterized by online measurements of electrical conductance
Authors: Ali Zulfiqar , Hong Le Hai , Ilisch Sybill , Busse Karsten , Radusch Hans‐Joachim
Published: March 2009

A new method based on the online measured electrical conductance is presented for the characterization of the kinetics of dispersion of organoclay in a polar rubber matrix during melt mixing. The charge carriers available in the clay galleries become released as a result of the dispersion processes; thus, the conductance of the nanocomposites is altering during mixing. A coupled conductance/temperature sensor installed inside the mixing chamber enables the online measurement of the electrical conductance during mixing. The online measured conductance shows a characteristic chart correlating to the nanoclay dispersion process. To clarify the structural background of the conductance curve the kinetics of macro‐ and microdispersion of nanoclay have been investigated with the use of optical microscopy, small‐angle X‐ray diffraction (SAXS), and atomic force microscopy (AFM), as well as bound rubber measurements. A close correlation was found between the online conductance chart and the development of the clay dispersion. In the first mixing step, breakdown of agglomerates, diffusion of polymer chains into the galleries of the clay, wetting, and intercalation processes take place simultaneously. As a result, a significant increase of conductance is observed during this period. Subsequently, the intercalated structures undergo the exfoliation process, which causes a further but moderate increase of the electrical conductance. © 2009 Wiley Periodicals, Inc.

Exfoliation of organically modified montmorillonite driven by molecular diffusion in maleated polypropylene
Authors: Meng Xiaoyu , Wang Zhe , Du Xiaohua , Wang Yanhui , Tang Tao
Published: March 2009

This work is focused on the factors influencing the intercalation of maleated polypropylene (PPMA) into organically modified montmorillonite (OMMT). Two kinds of PPMA were used to explore the optimal candidate for effective intercalation into OMMT. The grafting degree of maleic anhydride and the viscosity of PPMA have effects on the diffusion of polymer molecules. Moreover, the loading level of surfactant was varied to optimize the modification of montmorillonite because the appropriate loading level can provide a balance between interlayer distance and steric hindrance. The kind of surfactant changes the interaction between OMMT and PPMA, and accordingly the intercalation of PPMA is different, resulting in the discrepancy of the intercalation of PPMA. © 2009 Wiley Periodicals, Inc.

Graham little's theory of political leadership
Authors: Brett Judith
Published: March 2009

This paper examines the theory of political leadership developed by the Australian academic and writer on psychoanalysis and politics, Graham Little – a theory that both provides a general framework for understanding political leadership and posits three types that can be used to develop interpretations of contemporary and historical leaders. Building upon the typologies developed by Wilfred Bion, Little worked from both a deep knowledge of psychoanalytic theory and practice and from empirical work to write his interpretations of individual leaders, such as Margaret Thatcher and Ronald Reagan, and two recent Australian prime ministers, Bob Hawke and Paul Keating.

Isolation and characterization of farnesyl diphosphate synthase from the cotton boll weevil, Anthonomus grandis
Authors: Taban A. Huma , Tittiger Claus , Blomquist Gary J. , Welch William H.
Published: March 2009

Farnesyl diphosphate synthase (FPPS) catalyzes the consecutive condensation of two molecules of isopentenyl diphosphate with dimethylallyl diphosphate to form farnesyl diphosphate (FPP). In insects, FPP is used for the synthesis of ubiquinones, dolicols, protein prenyl groups, and juvenile hormone. A full‐length cDNA of FPPS was cloned from the cotton boll weevil, Anthonomus grandis (AgFPPS). AgFPPS cDNA consists of 1,835 nucleotides and encodes a protein of 438 amino acids. The deduced amino acid sequence has high similarity to previously isolated insect FPPSs and other known FPPSs. Recombinant AgFPPS expressed in E. coli converted labeled isopentenyl diphosphate in the presence of dimethylallyl diphosphate to FPP. Southern blot analysis indicated the presence of a single copy gene. Using molecular modeling, the three‐dimensional structure of coleopteran FPPS was determined and compared to the X‐ray crystal structure of avian FPPS. The α‐helical fold is conserved in AgFPPS and the size of the active site cavity is consistent with the enzyme being a FPPS. © 2009 Wiley Periodicals, Inc.

Biomolecular Oxidative Damage Activated by Enzymatic Logic Systems: Biologically Inspired Approach
Authors: Zhou Jian , Melman Galina , Pita Marcos , Ornatska Maryna , Wang Xuemei , Melman Artem , Katz Evgeny
Published: March 2009

Logical, responsible, practical. Enzymatic logic gates that process chemical input signals were used to trigger the release of redox‐active iron ions, which produce reactive oxygen species in a catalytic cascade, and thus result in oxidative damage in biomolecules. Functional coupling between enzymatic logic gates and oxidative damage systems resulted in “smart” biochemical ensembles that are activated upon receiving a certain pattern of biochemical signals.

magnified image

Systems that perform oxidative damage to biomolecules through catalytic cascades in the presence of iron‐redox labile species were activated by enzymatic logic gates that process chemical input signals according to built‐in logic operations. AND/OR enzymatic logic gates were composed of glucose oxidase (GOx) and GOx/esterase, respectively. The AND/OR logic functions of the enzyme gates were activated by application of glucose–oxygen and glucose–ethyl acetate input signals, respectively. The enzymatic logic gates, upon activation by specific patterns of the chemical input signals, produced acidic solutions and triggered release of redox labile iron species from a complex that is unstable under acidic conditions. This resulted in the activation of a catalytic cascade, which produced reactive oxygen species (ROS) and subsequently yielded oxidative damage in biomolecules. Functional integration of the enzyme‐based logic systems with the catalytic redox cascade that performs damage in biomolecules on demand is a first step towards “smart” systems capable of programmed detection, identification, and neutralization of potential biohazards.
In Vivo Modification of Native Carrier Protein Domains

Published: March 2009

Insider information: Selective labeling of endogenous proteins within cells has been an elusive goal. Here carrier protein labeling has been optimized for visualization, isolation, and protein sequencing.

magnified image

Carrier proteins are central to the biosynthesis of primary and secondary metabolites in all organisms. Here we describe metabolic labeling and manipulation of native acyl carrier proteins in both type I and II fatty acid synthases. By utilizing natural promiscuity in the CoA biosynthetic pathway in combination with synthetic pantetheine analogues, we demonstrate metabolic labeling of endogenous carrier proteins with reporter tags in Gram‐positive and Gram‐negative bacteria and in a human carcinoma cell line. The highly specific nature of the post‐translational modification that was utilized for tagging allows for simple visualization of labeled carrier proteins, either by direct fluorescence imaging or after chemical conjugation to a fluorescent reporter. In addition, we demonstrate the utility of this approach for the isolation and enrichment of carrier proteins by affinity purification. Finally, we use these techniques to identify a carrier protein from an unsequenced organism, a finding that validates this proteomic approach to natural product biosynthetic enzyme discovery.

Authors: Naqvi Tasneem Z. , Buchbinder Maurice , Zarbatany David , Logan Julie , Molloy Mia , Balke Glenn , Ainsworth Robert , Webb John G. , Alfieri Ottavio , Maisano Francesco
Published: March 2009

Background:

The edge‐to‐edge (Alfieri) technique for mitral valve repair is a versatile method of treating mitral insufficiency. Because of its simplicity, it has been applied in minimally invasive surgery, and recently, in the design of endovascular closed‐heart devices.

Aim:

The purpose of this study was to evaluate the acute in‐vivo safety and feasibility of a novel percutaneous mitral valve repair system based on Alfieri technique in an animal model.

Methods:

Under general anesthesia, 11 pigs (90–100 kgs), underwent percutaneous Alfeiri procedure. The right femoral vein was punctured and the mitral valve was approached via a standard transeptal puncture. Combined intracardiac echo and fluoroscopic guidance was used. The procedure included: the positioning of a guide catheter for multiple access to the left atrium and for directing devices; the use of a therapy device to capture the free edge of the mitral valve leaflets using vacuum, and to deliver the suture to the valve and finally the fixation with a Nitinol suture clip, and trimming of the suture with a fastener catheter.

Results:

Leaflet capture, suture placement, and suture‐clip deployment was successful in all 11 animals. There were no acute cardiac or access site complications. Procedural time (from wire in left atrium to completion of the procedure was 18 ± 9 min (range 9–30 min). Blood loss was 67 ± 44 ml (range 0–125ml). A double orifice configuration was visible by echocardiography at the end of the procedure in all animals.

Conclusion:

This acute animal study demonstrated the feasibility of a beating heart percutaneous Alfieri procedure in a non‐diseased porcine valve using an endovascular suturing device to safely access the mitral valve, place a stitch through the mitral valve leaflets, and deploy a suture‐clip that reproduces the surgical technique. Clinical application of this device in humans needs to be evaluated. © 2007 Wiley‐Liss, Inc.
Polymerase‐Catalysed Incorporation of Glucose Nucleotides into a DNA Duplex
Authors: Renders Marleen , Abramov Mikhail , Froeyen Matheus , Herdewijn Piet
Published: March 2009

Active but unselective: Nucleoside triphosphates possessing glucose moieties (such as those depicted) instead of the natural furanose rings are recognised by the active sites of polymerases. Polymerases therefore seem to be very unspecific in their recognition patterns.

magnified image

The enzymatic recognition of six‐membered ring nucleoside triphosphates—in particular the 6′‐triphosphates of (β‐D‐glucopyranosyl)thymine, (2′,3′‐dideoxy‐β‐D‐glucopyranosyl)thymine, (3′,4′‐dideoxy‐β‐D‐glucopyranosyl)thymine and (2′,3′‐dideoxy‐β‐D‐glucopyranosyl)adenine—was investigated. Despite the facts that the pyranose nucleic acids obtained by polymerisation of these monomers do not hybridise in solution with DNA and that the geometry of a DNA strand in a natural duplex differs from that of a pyranose nucleic acid, elongation of the DNA duplex with all four nucleotide analogues by Vent (exo−) polymerase was observed. Modelling experiments showed that hydrogen bonds are formed when 2′,3′‐dideoxy‐β‐homo‐T building blocks or β‐D‐gluco‐T building blocks are incorporated opposite adenosine residues in the template but not when they are incorporated opposite thymine residues in the template. The model shows a near perfect alignment of a secondary hydroxy group at the end of the primer and the α‐phosphate group of the incoming triphosphate. The results of these experiments provide new information on the role of the active site of the enzyme in the polymerisation reaction.

Published: March 2009

Curvy ligands for H2 storage? Enhancement of H2 adsorption has been observed in coordination framework materials, an example of which is depicted, by the introduction of phenanthrene and 9,10‐dihydrophenanthrene groups into porous CuII–carboxylate framework materials of NbO topology.

magnified image

Solvothermal reaction of the ligands H4L110 ((2,7‐phenanthrenediyl)diisophthalic acid) and H4L111 ([2,7‐(9,10‐dihydrophenanthrenediyl)]diisophthalic acid) with Cu(NO3)2⋅2.5 H2O in a slightly acidified mixture of DMF/1,4‐dioxane/H2O afforded the solvated framework compounds [Cu2(L110)(H2O)2](DMF)7.5(H2O)5 (NOTT‐110) and [Cu2(L111)(H2O)2](DMF)7.5(H2O)5 (NOTT‐111), respectively. Crystal structure determinations confirmed that NOTT‐110 and NOTT‐111 have the same NbO framework structure, differing only at the 9 and 10 positions of the phenanthrene group. The BET surface areas for desolvated NOTT‐110 and NOTT‐111 were estimated to be 2960 and 2930 m2 g−1, respectively. Compared with their phenyl analogues, introduction of phenanthrene groups to these porous CuII–carboxylate framework materials leads to an enhancement of H2 adsorption. Thus, the H2 isotherms for desolvated NOTT‐110 and NOTT‐111 confirm 2.64 and 2.56 wt % total H2 uptake, respectively, at 1 bar and 78 K. NOTT‐110 shows a high total H2 storage capacity of 7.62 wt % at 55 bar and 77 K (8.5 wt % at saturation) with a total volumetric capacity of 46.8 g L−1 at 55 bar and 77 K.
Radical Polymerization of Vinyl Acetate with Bis(tetramethylheptadionato)cobalt(II): Coexistence of Three Different Mechanisms
Authors: Kumar K. S. Santhosh , Gnanou Yves , Champouret Yohan , Daran Jean‐Claude , Poli Rinaldo
Published: March 2009

Poly(vinyl acetate) by OMRP: Increasing the steric encumbrance of the β‐diketonate R substituents in vinyl acetate (VAc) polymerization mediator [Co{OC(R)CHC(R)O}2] from Me to tBu sufficiently weakens the CoIIIPVAc bond of the polymer chain to allow it to operate by both associative (degenerative transfer) and dissociative (organometallic radical polymerization, OMRP) mechanisms (see scheme). The CoIIIPVAc species also acts as a transfer agent in the absence of Lewis bases, whereas the CoII complex shows catalytic chain transfer (CCT) activity.

magnified image

The complex [CoII(tmhd)2] (4; tmhd=2,2,6,6‐tetramethylhepta‐3,5‐dionato) has been investigated as a mediator for controlled radical polymerization of vinyl acetate (VAc) and compared with the analogue [CoII(acac)2] (1; acac=acetylacetonato). A relatively well controlled process occurs, after an induction time, with 2,2′‐azobis(4‐methoxyl‐2,4‐dimethylvaleronitrile) (V‐70) as radical initiator at 30 °C. However, whereas the polymerization essentially stops after about six initiator half‐lives in the presence of 1, it continues with a first‐order rate law in the presence of 4. The successful simulation of the kinetic data shows that 4 operates simultaneously by associative (degenerative transfer, DT) and dissociative (organometallic radical polymerization, OMRP) mechanisms. The occurrence of OMRP was confirmed by an independent polymerization experiment starting from an isolated and purified [Co(tmhd)2](PVAc) macroinitiator. The polymer molecular weight evolves linearly with conversion in accordance with the expected values for one chain per Co atom when DT is the predominant mechanism and also during the pure OMRP process; however, observation of stagnating molecular weights at long reaction times with concomitant breakdown of the first‐order rate law for monomer consumption indicates a competitive chain‐transfer process catalyzed by an increasing amount of CoII. In the presence of external donors L (water, pyridine, triethylamine) the DT pathway is blocked and the OMRP pathway is accelerated, and polymerization with complex 4 is then about five times slower than with complex 1. The reversal of relative effective OMRP rate constants keff (4>1 in the absence of external donors, 4<1 in their presence) is rationalized through competitive steric effects on CoIIIC and CoIIL bond strengths. These propositions are supported by 1H NMR studies and by DFT calculations.
Detection of Mismatched Duplexes by Synchronizing the Pulse Potential Frequency with the Dynamics of Ferrocene/Isoquinoline Conjugate‐Connected DNA Probes Immobilized onto Electrodes

Published: March 2009

Got a match? A novel electrochemical single‐nucleotide polymorphism (SNP) detection system has been developed by synchronizing the pulse potential frequency in square‐wave voltammetry with the dynamics of DNA duplexes consisting of ferrocene/isoquinoline conjugate‐connected DNA probes (see picture).

magnified image

Cyclic voltammetry was performed at various scan rates for the duplexes from ferrocene/isoquinoline conjugate‐connected DNA probes on gold electrodes. The relationship between the observed currents and the scan rates disclosed the enhanced bending elasticity of the mismatched duplexes compared with the fully matched duplexes. The difference of the dynamics was easily detected through the currents from the conjugate by adjusting the pulse potential frequency in square‐wave voltammetry. By using the present strategy, we succeeded in accurately detecting various naturally occurring single‐nucleotide polymorphisms.
