A new model for estimation of the thermal conductivity of polymer/clay nanocomposites
Authors: Mohaddespour Ahmad , Abolghasemi Hossein , Mostaedi Meisam Torab , Habibzadeh Sajjad
Published: May 2010

High density polyethylene– and polypropylene–clay nanocomposites are synthesized by melt blending, in which polyethylene glycol and polypropylene glycol are used as compatibilizers to increase the space of galleries. The morphology properties of nanocomposites are explored by X‐ray diffraction and transition electron microscopy. The thermal conductivity coefficient (K) of nanocomposites is also measured along with the thermal stability. A conventional model based on developed Maxwell‐Garnett formula is also established to predict the thermal conductivity of polymer/clay nanocomposites with clay loading. Morphology results indicate that two intercalated and exfoliated structures are formed. The established model satisfactorily predicts the K values of nanocomposites for low range of clay content. Thermogravimetric analysis shows remarkable thermal stability of nanocomposites with 10 wt % of clay content. The deviation of our model from experimental result for 10 wt % of clay can be attributed to the intercalated structure of layered silicates into the matrices. Although the K values do not considerably increase in 5 wt % with respect to the increase occurs for 10 wt % of clay, but it increases about 28 and 37% at 50°C for high density polyethylene– and polypropylene–clay nanocomposites, respectively. © 2010 Wiley Periodicals, Inc.

Effects of pigments on the UV degradation of wood‐flour/HDPE composites
Authors: Du Hua , Wang Weihong , Wang Qingwen , Zhang Zhengming , Sui Shujuan , Zhang Yanhua
Published: May 2010

The effects of different color pigments on the durability of wood‐flour/high‐density polyethylene composites (WF/HDPE) were evaluated by UV‐accelerated weathering tests. WF/HDPE composites were dyed using three different color inorganic pigments, which were added at 2% based on the weight of the composite. Samples were weathered in Q‐panel UV aging equipment for 1500 h. All samples showed significant fading and color changes in exposed areas. Changes in surface chemistry were studied using spectroscopic techniques. X‐ray photoelectron spectroscopy (XPS) was used to verify the occurrence of surface oxidation. Changes in carbonyl groups (CO), PE crystallinity, cellulose CO, and lignin aromatic CC were detected by Fourier transform infrared (FTIR) spectroscopy. The results indicate that surface oxidation occurred immediately within exposure 250 h for all samples; the surface of the control WF/HDPE composites was oxidized to a greater extent than that of the dyed WF/HDPE. This suggests that the addition of pigments to the WF/HDPE composites results in less weather‐related damage. The surface configuration observed by scanning electron microscopy revealed that WF/HDPE composites degraded significantly on accelerated UV aging, with dense cracking apparent on the exposed surface. Carbon black had a more positive effect on color stability than the other pigments. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010

Authors: Li Xiuhua , Xiao Daili , Meng Yuezhong
Published: May 2010

Two series of sulfonated multiblock copoly(ether‐ketone)s containing phthalazinone ether ketone and fluorene ether ketone moieties have been synthesized successfully by two‐step polycondensation. The water uptakes of the copolymers with varying sized sulfonated poly(phthalazinone ether ketone) block as hydrophilic blocks are moderate. In this series, polymer 10a gave the proton conductivity of 1.20 × 10−3 S/cm with IEC of 1.03. The water uptakes of the copolymers with varying sized sulfonated poly(fluorene ether ketone) blocks as hydrophilic blocks are high than 300%. These copolymers showed better proton conductivity. The copolymers with sulfonated poly(phthalazinone ether ketone) blocks had strong alcohol resistance at refluxing temperature. Whereas the copolymers containing sulfonated poly(fluorene ether ketone) hydrophilic blocks were dissolved in methanol and ethanol. The cast films of the title ionomers were transparent, ductile, and flexible. Moreover, these copolymers demonstrated greatly improved oxidative and thermal stabilities. Especially, the copolymers comprising sulfonated poly(phthalazinone ether ketone) hydrophilic blocks and poly(fluorene ether ketone) hydrophobic blocks is a promising proton exchange membrane material for proton exchange membrane fuel cell used methanol or ethanol as fuel. © 2010 Wiley Periodicals, Inc.

Structure and pervaporation performance of novel quaternized poly(vinyl alcohol)/γ‐aminopropyltriethoxysilane hybrid membranes
Authors: Zhang Qiu Gen , Liu Qing Lin , Meng Xiao Juan , Broadwell Ian
Published: May 2010

Novel hybrid organic–inorganic membranes were prepared via sol–gel reactions of quaternized poly(vinyl alcohol) (q‐PVA) and γ‐aminopropyltriethoxysilane (APTEOS) for pervaporation dehydration of an 85 wt % ethanol solution. The physicochemical structure of the hybrid membranes was characterized by FTIR, XRD, SEM, TG, and TEM. Nanofractal objects originated from self‐assembly of ammonium groups on the q‐PVA chains and amino groups in APTEOS can be observed on the surface of the hybrid membranes. When APTEOS/PVA ratio is 5% (wt/wt), the hybrid membrane has specific nervate networks on its surface and exhibits the highest separation factor. The hybrid membranes have better pervaporation performance than pristine q‐PVA membrane, and their permeation flux was found to increase linearly with increasing APTEOS content. © 2010 Wiley Periodicals, Inc.

Preparation of porous silk fibroin microparticles by a water‐in‐oil emulsification‐diffusion method
Authors: Baimark Yodthong , Srihanam Prasong , Srisuwan Yaowalak , Phinyocheep Pranee
Published: May 2010

Porous silk fibroin (SF) microparticles were prepared by a simple one‐step water‐in‐oil emulsification‐diffusion method. Aqueous SF solution and organic phase solvent were used as water and oil phases, respectively. Four organic solvents with different water solubility were studied, i.e., ethyl acetate, diethyl ether, dichloromethane, and chloroform. Influences of organic phase solvent, water/oil volume ratio, and SF concentration on SF microparticle characteristics were investigated. It was found that shape of the SF microparticles depended upon the type of organic phase solvent. The SF microparticles with hollow or bowl‐like shape were fabricated when organic solvents with higher water solubility, which are ethyl acetate and diethyl ether, were used as the continuous oil phase. While using organic solvents with lower water solubility, i.e., dichloromethane and chloroform resulted in the spherical shape SF microspheres. The water/oil volume ratios and the SF concentrations did not affect on the bowl‐like and spherical shapes of SF microparticles. Results from scanning electron microscope shows that all the SF microparticle matrices were porous structures. Using ethyl acetate and diethyl ether as the oil phase gave larger SF microparticle sizes than using dichloromethane and chloroform. The influences of water/oil volume ratio and the SF concentration showed slightly effect on the sizes of SF microparticles. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Dynamic mechanical properties of castor oil‐based polyurethane/epoxy graft interpenetrating polymer network composites
Authors: Chen Shoubing , Wang Qihua , Pei Xianqiang , Wang Tingmei
Published: May 2010

A series of graft interpenetrating polymer networks (IPNs) were prepared from epoxy (EP) and castor oil‐based polyurethane (PU). The dynamic mechanical properties, as well as the tensile and impact strength, of the IPNs were studied systematically. Results revealed that PU/EP IPNs showed improved damping properties compared with that of EP matrix. In addition, the PU content and testing frequencies had much influence on the damping properties of the IPNs. The IPN composites showed better damping properties with higher PU content or under higher testing frequencies. Mechanical analysis showed that the tensile strength of IPN composites was higher than that of pure EP. However, higher PU content (beyond 5 wt %) impaired the impact strength of the IPNs. It is expected that PU/EP IPNs may be potentially used as structural damping materials. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Hydrothermal Synthesis of Platinum‐Group‐Metal Nanoparticles by Using HEPES as a Reductant and Stabilizer
Authors: So Man‐Ho , Ho Chi‐Ming , Chen Rong , Che Chi‐Ming
Published: May 2010

Platinum‐group‐metal (Ru, Os, Rh, Ir, Pd and Pt) nanoparticles are synthesized in an aqueous buffer solution of 4‐(2‐hydroxyethyl)‐1‐piperazineethanesulfonic acid (HEPES) (200 mM, pH 7.4) under hydrothermal conditions (180 °C). Monodispersed (monodispersity: 11–15 %) metal nanoparticles were obtained with an average particle size of less than 5 nm (Ru: 1.8±0.2, Os: 1.6±0.2, Rh: 4.5±0.5, Ir: 2.0±0.3, Pd: 3.8±0.4, Pt: 1.9±0.2 nm). The size, monodispersity, and stability of the as‐obtained metal nanoparticles were affected by the HEPES concentration, pH of the HEPES buffer solution, and reaction temperature. HEPES with two tertiary amines (piperazine groups) and terminal hydroxyl groups can act as a reductant and stabilizer. The HEPES molecules can bind to the surface of metal nanoparticles to prevent metal nanoparticles from aggregation. These platinum‐group‐metal nanoparticles could be deposited onto the surface of graphite, which catalyzed the aerobic oxidation of alcohols to aldehydes.
Repairing topological inconsistency of mesh sequences
Authors: Feng Wei , Zhang Hongxin , Huang Jin , Wang Caoyu , Bao Hujun
Published: May 2010

We propose a novel approach for repairing topological inconsistency of mesh sequences with a few user interactions. The main idea of our approach is to leverage curve skeletons to detect the inconsistency of a mesh sequence. The skeleton of one mesh in the sequence is edited by user, which produces a prototype skeleton. We propagate this prototype using graph matching in‐between frames. By using temporal coherence cues, the matching procedure can be dramatically accelerated. Finally, the mesh sequence is repaired according to the inconsistencies by comparing matched skeletons and original skeletons. As demonstrated in the results, our approach avoids manually editing in all meshes, and is able to output a mesh sequence with consistent topology. Copyright © 2010 John Wiley & Sons, Ltd.
Eyelid kinematics for virtual characters
Authors: Steptoe William , Oyekoya Oyewole , Steed Anthony
Published: May 2010

When compared to gaze, animation of the eyelids has been largely overlooked in the computer graphics literature. Eyelid movement plays an important part both in conveying accurate gaze direction and in improving the visual appearance of virtual characters. Eyelids have two major motion components: lid saccades that follow the vertical rotation the eyes, and blinking. Derived from literature in ophthalmology and psychology, this paper presents parametric models for both motion types, and emphasizes their dynamic temporal behaviour. Experimental validation classifies model‐generated animation as similar to that encoded from expensive motion captured data, and significantly exceeding linearly interpolated animation.

Rigging transfer
Authors: Seo Jaewoo , Seol Yeongho , Wi Daehyeon , Kim Younghui , Noh Junyong
Published: May 2010

Realistic character animation requires elaborate rigging built on top of high quality 3D models. Sophisticated anatomically based rigs are often the choice of visual effect studios where life‐like animation of CG characters is the primary objective. However, rigging a character with a muscular‐skeletal system is very involving and time‐consuming process, even for professionals. Although, there have been recent research efforts to automate either all or some parts of the rigging process, the complexity of anatomically based rigging nonetheless opens up new research challenges. We propose a new method to automate anatomically based rigging that transfers an existing rig of one character to another. The method is based on a data interpolation in the surface and volume domain, where various rigging elements can be transferred between different models. As it only requires a small number of corresponding input feature points, users can produce highly detailed rigs for a variety of desired character with ease. Copyright © 2010 John Wiley & Sons, Ltd.
Animation transplantation
Authors: Süßmuth Jochen , Zollhöfer Michael , Greiner Günther
Published: May 2010

We present a novel method to animate a static geometry by cloning a captured animation sequence. More precisely, given a sequence of range scans of a deforming object which has been captured by a real‐time 3D scanner, we describe a novel algorithm to clone the animation of the recorded geometry onto another triangle mesh. To achieve this, we reconstruct a coherent animated mesh of the input sequence using a template deformation approach. Then we employ a new algorithm for robust marker‐less non‐rigid registration to deform one frame of the generated animation such that it matches a different 3D model. The resulting registration is further used to find correspondences between the animation and the target object which are in turn used to transfer the animation of the recorded sequence onto the target shape. Transferring the entire geometry of the animations results in very convincing facial expressions since even the smallest expression wrinkles are preserved. We evaluate the robustness and the performance of the proposed algorithms using a variety of data sets, including facial animations and whole body animations. Copyright © 2010 John Wiley & Sons, Ltd.
Pipeline Flow Behavior of Water‐in‐Oil Emulsions with and without a Polymeric Additive in the Aqueous Phase
Authors: Omer A. , Pal R.
Published: May 2010

New experimental results are presented on the pipeline flow behavior of water‐in‐oil (W/O) emulsions with and without a polymeric additive in the aqueous phase. The emulsions were prepared from three different oils of different viscosities (2.5 mPa s for EDM‐244, 6 mPa s for EDM‐Monarch, and 5.4 mPa s for Shell Pella, at 25 °C). The W/O emulsions prepared from EDM‐244 and EDM‐Monarch oils (without any polymeric additive in the dispersed aqueous phase) exhibited drag reduction behavior in turbulent flow. The turbulent friction factor data of the emulsions fell well below the Blasius equation. The W/O emulsions prepared from EDM‐244 oil exhibited stronger drag reduction as compared with the EDM‐Monarch oil. The W/O emulsions prepared from Shell Pella oil exhibited negligible drag reduction in turbulent flow and their friction factor data followed the Blasius equation. The Shell Pella emulsions were more stable than the EDM‐244 and EDM‐Monarch emulsions. When left unstirred, the EDM‐244 and EDM‐Monarch emulsions quickly coalesced into separate oil and water phases whereas the Shell Pella emulsions took a significantly longer time to phase separate. The Shell Pella oil emulsions were also milkier than the EDM emulsions. The addition of a polymer to the dispersed aqueous phase of the W/O emulsions had a significant effect on the turbulent drag reduction behavior.
Study of Aromatic Compounds Derived from Sugarcane Bagasse. Part I: Effect of pH
Authors: Al Arni S. , Drake A. F. , Del Borghi M. , Converti A.
Published: May 2010

This work aims at increasing the knowledge about the recovery of aromatic compounds from the lignin fraction of sugarcane bagasse, as well as exploring the possibility to recover these fine chemicals of great concern for many industrial sectors. The major natural products contained in the lignin fraction of such a straw material were extracted in previous work by alkaline hydrolysis using different concentrations of NaOH and amounts of bagasse, and HPLC analyses revealed that the extracts mainly contained p‐coumaric acid, ferulic acid, syringic acid, and vanillin, the first three containing and the last lacking a carboxyl group. All these aromatic compounds have well‐known antioxidant power and are very important in pharmacology. For these reasons, they have been investigated in this study by UV spectrophotometry, with special concern to the pH effect on their spectra and determination of their pKa values.
Influence of Bubble Evolution on the Effective Kinetics of Heterogeneously Catalyzed Gas/Liquid Reactions. Part I: Reactions with Gaseous Products
Authors: Oehmichen T. , Datsevich L. , Jess A.
Published: May 2010

For heterogeneously catalyzed multiphase reactions the formation of bubbles may have an influence on mass and heat transfer as well as on the effective reaction rate. This first of two contributions deals with the Ni‐catalyzed decomposition of H2O2, which was used as a model system for an (almost) isothermal reaction with a gaseous product. (In part II the strongly exothermic hydrogenation of hexene will be analyzed, where gas/vapor bubbles may be generated by overheating of the catalyst.) The discharge of O2 bubbles formed by decomposition of H2O2 enhances the external mass and heat transfer up to one order of magnitude. This is in analogy to the well‐known phenomena during nucleate boiling. The experiments and theoretical considerations also show that the internal mass transfer depends on the intensity of the reaction and thus on the H2O2 concentration, which is in contradiction to the classical Thiele approach. This discrepancy could be explained by a modified model that takes the formation of bubbles into account.
A Simple Model for Turbulent Boundary Layer Momentum Transfer on a Flat Plate
Authors: Khademi M. H. , Zeinolabedini Hezave A. , Mowla D. , Taheri M.
Published: May 2010

A simple model is presented for turbulent momentum transfer on a flat plate. The proposed model is based on some polynomial velocity profiles in a laminar sublayer as well as in a fully developed boundary layer and two integral boundary layer equations. The model could be used for the calculation of boundary layer thickness, velocity profile and skin friction factor on the flat plate. The calculated results are in very good agreement with other proposed empirical correlations.
Effect of Electric Double Layer Repulsion on Oil Droplet Coalescence Process
Authors: Zhang L. , Xu B. , Jiang B. , Liu Y.
Published: May 2010

Film drainage between two droplets approaching each other at constant velocity under the influence of electric double layer repulsion is studied systematically. Based on the lubrication equations, a mathematical model is given to govern the evolution of film drainage between two oil droplets. This model consists of three coupled fourth‐order nonlinear parabolic partial differential equations describing the dynamic evolution of the film thickness, film pressure and surfactant interfacial concentration. The numerical method used is the finite element method. The main objective of this research work is to modify the film pressure equation by considering the electric double layer repulsion. The effects of electric double layer repulsion and viscosity ratio on film drainage are investigated theoretically.
Combined Effect of Agitation/Aeration and Fed‐Batch Strategy on Ubiquin‐ one‐10 Production by Pseudomonas diminuta
Authors: Bule Mahesh V. , Singhal Rekha S.
Published: May 2010

The effects of aeration rate and agitation speed on ubiquinone‐10 (CoQ10) submerged fermentation in a stirred‐tank reactor using Pseudomonas diminuta NCIM 2865 were investigated. CoQ10 production, biomass formation, glycerol utilization, and volumetric mass transfer coefficient (kLa) were affected by both aeration and agitation. An agitation speed of 400 rpm and aeration rate of 0.5 vvm supported the maximum production (38.56 mg L–1) of CoQ10 during batch fermentation. The fermentation run supporting maximum production had an kLa of 27.07 h–1 with the highest specific productivity and CoQ10 yield of 0.064 mg g–1h–1 and 0.96 mg g–1 glycerol, respectively. Fermentation kinetics performed under optimum aeration and agitation showed the growth‐associated constant (a = 5.067 mg g–1) to be higher than the nongrowth‐associated constant (β = 0.0242 mg g–1h–1). These results were successfully utilized for the development of fed‐batch fermentation, which increased the CoQ10 production from 38.56 mg L–1 to 42.85 mg L–1.
