Die Stöchiometrie der Olympischen Spiele: citius, altius, fortius – schneller, höher, stärker
Authors: Roth Klaus 
Published: August 2008

AbstractBei den Olympischen Spielen in Peking wird eine gewaltige Menge Chemie ablaufen. Es geht nicht etwa um Doping, zumindest hoffen wir dies, sondern um über 10.000 teilnehmende Sportlerinnen und Sportler, die weit über 400.000 kg Adenosintriphosphat in ihren Muskeln abbauen und wieder aufbauen werden. Wegen dieser imposanten Zahl sollten wir diesem kleinen Molekül deutlich mehr Aufmerksamkeit schenken, denn wir haben gelernt: Erst ATP macht die Olympischen Spiele überhaupt möglich.
Agonist ist nicht gleich Agonist
Authors: Hille‐Rehfeld Annette 
Published: August 2008

AbstractVerschiedene Liganden ein‐ und desselben Rezeptors können unterschiedliche Wirkungen auslösen, sie zeigen funktionelle Selektivität. So wirken einige, aber nicht alle Agonisten des Typ2A‐Serotoninrezeptors halluzinogen. Das liegt offenbar an der Komplexität des vom Rezeptor gesteuerten Netzwerks der Signaltransduktion. Die von der Natur vorgegebene Vielfalt weckt Hoffnung auf maßgeschneiderte Medikamente.

Recent Development of Biodegradable Network Polyesters Obtained from Renewable Natural Resources
Authors: Tsutsumi Naoto , Kono Yoichiro , Oya Masaya , Sakai Wataru , Nagata Minoru 
Published: August 2008

AbstractCurrent technological interests in chemistry have involved research into renewable carbon to help supply the world's chemical needs. Renewable and natural resources‐based biodegradable polymers are environmentally useful for the establishment of recycled systems. In the past decade, novel network polyester and films of glycerol with dicarboxylic acids with various lengths of methylene units have been developed and their favorable properties of enzymatic degradability and biodegradability have been reported. In the present paper, optically active network polyesters are prepared from malic acids and their biodegradability in enzymatic solution and in activated sludge is investigated. In addition, biodegradable polyesters of gluconolactone with citric acid are developed. The application and biodegradability of these network polyesters for future technological applications are also discussed.
Synthesis and Characterization of Branched‐Chain Derivatives of Methyl Oleate
Authors: Dailey Oliver D. , Prevost Nicolette T. , Strahan Gary D. 
Published: August 2008

AbstractOleic acid is one of the most abundant fatty acid components of the triglycerides in many vegetable oils, such as cottonseed oil. As part of a project to develop new and expanded uses of oilseed products and by‐products (such as biodiesel, fuel additives, and lubricants), studies were conducted on the synthetic conversion of oleic acid (in ester form) to branched‐chain fatty acid esters. In these studies, methyl oleate was brominated in the allylic position and subsequently treated with organocuprate reagents to produce novel branched‐chain derivatives (ethyl, n‐butyl, n‐hexyl, phenyl). Details of the syntheses, characterization (GC/MS and NMR), and the properties of the products (with emphasis on low‐temperature properties) are discussed. Several of the synthesized products exhibited significantly lower re‐crystallization temperatures in comparison with methyl oleate and may prove useful as additives to biodiesel for use at low temperatures.
Friction Reducing Properties and Stability of Epoxidized Oleochemicals
Authors: Doll Kenneth M. , Sharma Brajendra K. , Erhan Sevim Z. 
Published: August 2008

AbstractThe properties of epoxidized oleochemical methyl esters were studied. Epoxidized soybean oil, epoxidized methyl oleate, epoxidized methyl linoleate, and epoxidized methyl linolenate were compared with each other and with similar series of unmodified olefins. Several interesting trends were uncovered including: epoxidation of olefinic materials improves their oxidative stability, epoxidation of oleochemicals increases their adsorption to metal surfaces, and epoxidation has a deleterious effect on the pour point and viscosity index of the oleochemicals. In addition, a simple qualitative method where lubrication performance can be compared by examination of wear scars generated by ball‐on‐disk friction measurement under a simple optical microscope is reported.
Clean and Green Bioplastic Composites: Comparison of Calcium Sulfate and Carbon Nanospheres in Polylactide Composites
Authors: Sobkowicz Margaret J. , Feaver Jonathan L. , Dorgan John R. 
Published: August 2008

AbstractTwo environmentally friendly fillers, carbon nanospheres (CNS) derived from cellulose and calcium sulfate anhydrite (CaSO4), a by‐product of the polylactide (PLA) production process, are compared as nucleating agents in commercial‐grade PLA. CNS and CaSO4are compounded with PLA using solution blending. Additionally, CaSO4is melt mixed with PLA. Crystallization kinetics are explored using differential scanning calorimetry (DSC) and polarized optical microscopy. Mechanical properties are examined using dynamic mechanical thermal analysis (DMTA) and morphology is determined using field‐emission scanning electron microscopy (FE‐SEM). It is found that the filler does not increase the PLA crystallization rates significantly at loadings up to 15 wt% (CNS) or 20 wt% (CaSO4). The lack of effect on crystallization kinetics is attributed to the highD‐lactic acid content of commercial‐grade PLA, and also to poor dispersion of the fillers in the PLA matrix. The glassy shear storage modulus of the composites is found to increase by 50% in the highest weight loadings tested. These clean and green bioplastic composites may be able to offset the use of fossil resource‐based materials.
Improved Sugar Release from Lignocellulosic Material by Introducing a Tyrosine‐rich Cell Wall Peptide Gene in Poplar

Published: August 2008

AbstractLignin degradation is of critical importance in biomass utilization of woody plants, because the presence of lignin limits hydrolytic enzyme access to cellulose and hemicellulose. To date, strategies for lignin removal have ranged from treatment with lignin‐degrading fungi to genetic manipulations that reduce lignin content or modify monolignol composition. However, reducing lignin content without compromising tree fitness can be difficult. An alternate approach to modify lignin composition by introducing in situ peptide cross‐links is reported here. The hypothesis was that introducing in situ peptide cross‐links would not change overall lignin content or distribution in the cell wall, yet should render the lignin more susceptible to protease digestion. To test this, a transgene encoding a high tyrosine‐content peptide was designed to express in lignifying tissues of hybrid poplar. Relative to wildtypes, the transgenics had no change in total lignin content or overall plant morphology, although the wood in a number of lines had reduced storage modulus. As predicted, a number of transgenic lines were more susceptible to protease digestion than wildtypes, resulting in a higher polysaccharide release from the lignocellulose complexes. Although preliminary, these results suggest that this may be a viable means to facilitate lignin removal and potentially advance the utilization of woody biomass as a biofuel feedstock.
Chemotaxis‐mediated scission contributes to efficient cytokinesis in Dictyostelium
Authors: Nagasaki Akira , Uyeda Taro Q. P. 
Published: August 2008

AbstractInterphase amoeba of Entamoeba invadens are attracted to the furrowing region of a neighboring dividing cell to assist with the division. A seemingly similar behavior has been observed in Dictyostelium discoideum, but in this case, it has not been shown whether the movements were truly directed toward the furrowing region or whether they have any relevance. We thus used myosin II‐null cells, which spend more time than wild type cells in cytokinesis, and successfully demonstrated that nearly half of the division events involve the attraction of a neighbor cell to the furrowing region. Cells lacking the β subunit of the trimeric G protein (Gβ), which are incapable of chemotaxis, did not show such midwifery. Culturing wild type cells flattened under agarose sheets also slowed the cytokinesis process, and this allowed us to demonstrate that phosphatidylinositol trisphosphate was enriched in the anterior region of midwifing cells, consistent with the view that midwifery in D. discoideum is also chemotaxis. On substrates, while only 3.6% of wild type cells were multinucleate, 8.1% of Gβ‐null cells were multinucleate, and this was reduced to 3.4% when they were surrounded by wild type cells. Conversely, multinucleated wild type cells increased to 6.8% when they were surrounded by Gβ‐null cells. Thus, Gβ‐null cells frequently fail to divide because they cannot assist each other's division and midwifery ensures successful cytokinesis in Dictyostelium discoideum. Cell Motil.

Trading off logging overhead and coordinating overhead to achieve efficient rollback recovery
Authors: Yang Jin‐Min , Li Kin Fun , Li Wen‐Wei , Zhang Da‐Fang 
Published: August 2008

AbstractIn the rollback recovery of large‐scale long‐running applications in a distributed environment, pessimistic message logging protocols enable failed processes to recover independently, though at the expense of logging every message synchronously during fault‐free execution. In contrast, coordinated checkpointing protocols avoid message logging, but they are poor in scalability with a sharply increased coordinating overhead as the system grows. With the aim of achieving efficient rollback recovery by trading off logging overhead and coordinating overhead, this paper suggests a partitioning of the system into clusters, and then presents a scheme to implement the conversion between these overheads. Using the proposed conversion, coordination can be introduced to reduce the unbearable logging overhead found in some systems, whereas proper logging can be employed to alleviate the unacceptable coordinating overhead in others. Furthermore, heuristics are introduced to address the issue of how to partition the system into clusters in order to speed up the recovery process and to improve recovery efficiency. Performance evaluation results indicate that our scheme can lower the overall system overhead effectively. Copyright © 2008 John Wiley & Sons, Ltd.
Oxidation of Lignin Using Aqueous Polyoxometalates in the Presence of Alcohols
Authors: Voitl Tobias , Rudolf von Rohr Philipp 
Published: August 2008

AbstractA novel approach has been developed in order to use Kraft lignin as a renewable resource for the production of chemicals. The concept is based on the use of polyoxometalates as reversible oxidants and on the use of radical scavengers, which prevent lignin fragments from repolymerizing. The oxidation of Kraft lignin, which is a potential source of functionalized phenols, by H3PMo12O40 in water yields a relatively small amount of monomeric species detected by GC‐MS. The addition of methanol to the reaction resulted in an increase in the yield of monomeric products by a factor of up to 15. Vanillin and methyl vanillate are the main products obtained, in a maximum yield of 5 wt % based on dry Kraft lignin. Methanol plays a decisive role in the prevention of repolymerization by reducing lignin–lignin condensation reactions. Furthermore, it is proposed that methanol generates small amounts of .CH3 and CH3O. radicals through the acid‐catalyzed formation of dimethyl ether which couple with lignin fragments.
A method for acceptability region representation in analogue linear networks
Authors: Grasso Francesco , Manetti Stefano , Piccirilli Maria Cristina 
Published: August 2008

AbstractA new simple approach to acceptability region representation in analogue linear circuit design is presented. The proposed method is also able to characterize non‐convex and disjoint acceptability regions with low computational effort. In fact, the developed procedure is based on the use of symbolic analysis techniques, which permit one to perform only one simulation of the circuit under consideration, thus reducing the computational efforts. The theoretical basis and the algorithm implementing the technique are presented. A circuital example is also included. Copyright © 2008 John Wiley & Sons, Ltd.
