Between Globalization and Particularization of Memories: Screen Images of the Holocaust in Germany and Poland
Authors: Stimmel Joanna K. 
Published: June 2007

With the increasing medialization of cultural memory regardingWorld War II and the Holocaust, cinematic texts become significantcomponents of our remembrance. Not only videotaped witness testimoniesbut also documentaries and fictional films make up the growingbody of visual material that tells of the wartime past and the waywe remember it. Today, the great majority of the filmmakers depictingthe Holocaust on screen—as well as their audiences—belong tothe so-called second and third generations. Born too late to have witnessedthe murder of Europe’s Jews, these film directors nonethelessdeclare a very strong personal connection to the past they neverknew. Their renditions of this past is, as Marianne Hirsch argues,driven by the “postmemory,” a type of memory in which the connectionto its object or source is mediated not through recollectionbut rather through imagination and creation.
Control of uncertain nonlinear systems with arbitrary relative degree and unknown control direction using sliding modes
Authors: Oliveira T. R. , Peixoto A. J. , Nunes E. V. L. , Hsu L. 
Published: June 2007

AbstractThe control of uncertain nonlinear systems by output feedback is addressed. A model‐reference tracking sliding mode controller is designed for uncertain plants with arbitrary relative degree. Nonlinearities of a given class are incorporated as state dependent and possibly unmatched disturbances of a linear plant. Such class encompasses nonlinear systems which are triangular in the unmeasured states. In contrast with previous works, exact tracking is achieved by means of a switching strategy based on a locally exact differentiator, and a monitoring function is used to cope with the lack of knowledge of the control direction. Global or semi‐global stability properties of the closed‐loop system are proved. Copyright © 2007 John Wiley & Sons, Ltd.

AbstractThe effect of dispersant structures for dispersing single‐walled carbon nanotubes (SWCNTs) is investigated. The monomer 3‐hexylthiophene is used as the starting material for the development of a series of oligomers that are used to disperse SWCNTs in an organic solvent. The series is obtained by varying the number of head groups, the regioregularity of head groups, and the head‐to‐tail ratios of the hexyl group in the oligomers. The SWCNT solutions are characterized with UV‐vis–near‐IR spectroscopy and transmission electron microscopy. An increase in the number of head groups improves the dispersity of SWCNTs, and a regioregular oligomer plays an important role in dispersing SWCNTs. Furthermore, Raman spectroscopy and X‐ray photoelectron spectroscopy shows that the sulfur atom head groups enhance interactions between the thiophenes and the SWCNT walls. The analysis demonstrated that a well‐designed thiophene oligomer could afford well‐dispersed SWCNT solutions with long‐term dispersion stability, even with an extremely low dispersant concentration (weight ratio of CNTs/dispersant is one and the dispersant concentration is 0.1 g L–1).
Controlling the Structure and Morphology of Monodisperse Polystyrene/Polyaniline Composite Particles
Authors: Wu Q. , Wang Z. , Xue G. 
Published: June 2007

AbstractThe fabrication of a conducting polyaniline (PANi) matrix based on a template of polystyrene (PS) latex is of interest from an academic and application viewpoint. In this Full Paper, we propose a distinctly novel strategy, which involves swelling followed by diffusion and polymerization at the interface, to fabricate PANi‐coated PS microspheres with uniform size and well‐defined shape, regardless of the type of “naked” PS seed particles. Compared to the widely used conventional synthetic protocol, this method affords much more effective control over the structure and morphology of the resultant composites by simply changing the aniline/PS weight ratio or the rate of addition of the doping agent. In addition, it guarantees the easy and successful production of a hollow nanostructure of a conducing polymer with a uniform, intact shell. The synthesized composites have been characterized using Fourier transform infrared spectroscopy, C, H, and N elemental microanalyses, and transmission electron microscopy. The mechanism governing the formation of the composites is discussed.
CFD modeling of binary‐fluidized suspensions and investigation of role of particle–particle drag on mixing and segregation
Authors: Owoyemi Olumuyiwa , Mazzei Luca , Lettieri Paola 
Published: June 2007

AbstractA model is presented for the prediction of the fluid dynamic behaviour of binary suspensions of solid particles fluidized by Newtonian fluids. The equations of motion for the fluid and solid phases are derived by extending the averaged two‐fluid equations of change for identical spheres in Newtonian fluids developed by Anderson and Jackson and Jackson. A new closure relationship for the fluid–particle interaction force is employed and a new numerical algorithm is developed to control the solid compaction in each particle phase. The article also presents a comparison between three different equations of closure for the particle–particle drag implemented within the model. Predictions of the fluidization behavior obtained by the proposed model are validated against experimental results in terms of solid mixing and segregation, bed expansion and bubble dynamics. Two‐dimensional CFD simulations are performed in a bed of rectangular geometry using ballotini with particle sizes of 200 and 350 μm. © 2007 American Institute of Chemical Engineers AIChE J, 2007
Blood compatibility and mechanical properties of oxidized‐chitosan films
Authors: Yang Yuedong , Zhou Yongguo , Chuo Huimin , Wang Shuyuan , Yu Jiugao 
Published: June 2007

AbstractBy dipping chitosan films into saturated NO2–glacial acetic acid solution, the hydromethyl groups on the film surface could be oxidized to carboxyl groups and the blood compatibility of the films improved. Fourier transform infrared (FTIR) spectra indicated the presence of many COOH and COO− groups on the modified membrane surface. Scanning electron microscopy (SEM) showed that the surface of the modified membrane was rough, as compared with the chitosan film, which possessed a smooth surface. In the oxidation process, with increased dipping time of the films in saturated NO2–glacial acetic acid solution, the tensile strength of the films decreased slowly initially, and rapidly 10 h later. The swelling ratio of the modified chitosan film increased obvious noticeably as the degree of oxidation of the film increased. All antithrombosis and hemolysis tests and blood cell morphology observation with SEM revealed that the blood compatibility of modified chitosan membranes is superior to that of chitosan films. © 2007 Wiley Periodicals, Inc.

Published: June 2007

AbstractIn this research, diazophenylene bridged metal‐phthalocyanine (Pc) polymers were produced from diazonium salt of 1,4‐diaminophenylene and presynthesized 1,8,15,22‐tetraamino metal‐Pcs. 1,8,15,22‐Tetraamino metal‐Pc complexes of Co, Ni, Cu, Ce, and Er were obtained by reducing 1,8,15,22‐tetranitro metal‐Pc complexes synthesized from 3‐nitrophthalic anhydride, urea, metal salt, and ammonium molybdate catalyst. Complexes and polymers were characterized by Fourier transform infrared (FTIR), ultraviolet–visible (UV–vis), and X‐ray powder diffraction spectroscopes. X‐ray analysis of the polymers showed that there were short‐range orientations in the polymers. Thermal analysis of the complexes and the polymers were done by differential scanning calorimeter (DSC) and thermal gravimetric analysis (TGA) at a heating rate of 10°C min−1 under nitrogen atmosphere. Ash analysis was performed to determine the metal content of the polymers. Viscosimetry and ebullioscopy measurements of the soluble part of the polymers were done for molecular weight analysis of the soluble part in tetrahydrofuran (THF) at 25°C. Four‐probe conductivity measurements on isothermal conditions revealed that the polymer samples showed 104 fold increases in their electrical conductivities when doped with iodine. © 2007 Wiley Periodicals, Inc.

Preparation and characterization of novel sodium alginate/chitosan two ply composite membranes
Authors: Ma Lihua , Yu Weiting , Ma Xiaojun 
Published: June 2007

AbstractSodium alginate/chitosan (SA/CS) two ply composite membranes were prepared by casting and solvent evaporation technique. NaHCO3 was used as a porogen additive to form pores in the interior of the composite membranes and glycerol was introduced as a plasticizer. The water uptake capacity, mechanical strength, oxygen permeation property, and in vitro cytotoxicity were evaluated to test the feasibility to utilize the composite membranes for wound dressing. The average pore size, water uptake capacity, and oxygen permeation property of the composite membranes could be adjusted by the ratio of NaHCO3 in the SA solution. The SA/CS two ply composite membranes showed high water uptake capacity, suitable mechanical strength, excellent oxygen permeability, and good biocompatible. It indicates that the SA/CS two ply composite membranes are suitable for wound dressing application. It provides a simple but promising platform to fabricate wound dressing using natural polymers. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
Disulfiram is an Inhibitor of Human Purified Monoacylglycerol Lipase, the Enzyme Regulating 2‐Arachidonoylglycerol Signaling
Authors: Labar Geoffray , Bauvois Cédric , Muccioli Giulio G. , Wouters Johan , Lambert Didier M. 
Published: June 2007

AbstractMonoacylglycerol lipase (MAGL) is a key enzyme responsible for the termination of endocannabinoid signaling. Its crucial role in 2‐arachidonoylglycerol (2‐AG) metabolism, together with the numerous pharmacological properties mediated by this endocannabinoid, emphasize the interest in MAGL as therapeutic target, along with the need to design potent and selective inhibitors. Meanwhile, the complexity of 2‐AG degradation pathways underscores the need to use a purified source of enzyme in evaluation studies of new inhibitors. We report here the first heterologous expression and purification of human MAGL. A highly pure protein was obtained and allowed us to measure the affinity of several MAGL inhibitors for the human enzyme. Importantly, disulfiram (tetraethylthiuram disulfide), a compound used to treat alcoholism, and other disulfide‐containing compounds were shown to inhibit MAGL with good potency, likely through an interaction with cysteine residues.

AbstractThe reactivity of a range of pyridone and pyrazinone derivatives towards alkynes in the presence of cyclopentadienylcobaltbis(ethene) has been investigated. Depending on the nature of the substrates, [2+2+2]‐ or [2+2] cycloaddition, CH, or NH activation may occur. In the case of pyridones, the first three predominated with N‐protected derivatives, whereas substrates containing NH bonds followed an NH activation pathway. The [2+2+2] cycloaddition of an N‐butynylisoquinolone was applied successfully to the total synthesis of anhydrolycorinone. Pyrazinone substrates showed similar patterns of reactivity.
Selective Tuning of the Band Gap of π‐Conjugated Dithieno[3,2‐b:2′,3′‐d]phospholes toward Different Emission Colors

Published: June 2007

AbstractThe systematic extension of the π‐conjugated system of strongly blue‐luminescent dithieno[3,2‐b:2′,3′‐d]phospholes has been investigated with the goal of obtaining different emission colors. Functionalization of the 2‐ and 6‐position of the dithienophosphole scaffold with halogen substituents provided functional building blocks for subsequent cross‐coupling experiments with various homo‐ and heteroaryls to selectively decrease the band gap of the materials. By this strategy materials with different emission colors ranging from green via yellow to orange could be obtained. This feature supports their suitability for organic light‐emitting diodes with respect to an application in full‐color flat‐panel displays. The experimental results were nicely supported by theoretical DFT calculations providing a deeper understanding of the electronic structure in the extended materials, and also allowing for the design of future materials based on a dithienophosphole core. Furthermore, the phosphorus center in the extended molecular materials can efficiently be fine‐tuned in subsequent simple chemical functionalizations. This allows for a tailoring of the optoelectronic properties of the extended dithienophospholes to suit the requirements of potential applications.
