Published: September 2012

During the last decade, most organizations have implemented enterprise-wide applications and integration platforms. These implementations have delivered benefits in terms of data synchronization and information flows within the organization, and with trading partners providing valuable inputs for planning and optimization of schedules and reporting. The best and the most important technology of these technologies is RFID or Radio Frequency Identification systems. RFID is one of the most promising and the most advanced technologies released in recent years. Perishable and short life products, especially foodstuffs, are those cases causing the largest problems and challenges for supply chain management. These challenges are mainly due to the variety in the number of products, special needs for tracing and tracking the product flow during the supply chain, the short life of the products, the requirement for controlling the temperature in the supply chain and the high volume of the products we deal with. Using the RFID system is one of the best potential solutions helping the supply chain management solve logistic problems of spoilable products. In food industries, the period of the product storage is short due to the high probability that the product spoils and the short time of the storage of the final product. Today, the changes in the ways of producing, distributing, maintaining and selling foodstuffs have caused changes in consumers' demands to increase the quality and the durability of foodstuff packages. Innovations are created in this industry to make sure of the desirable performance of packing in the supply chain of the foodstuffs, such as active or intelligent packing methods.

Towards data‐based adaptive control
Authors: Datta Aniruddha , Layek Ritwik , Nounou Hazem , Nounou Mohamed , Mohsenizadeh Navid , Bhattacharyya Shankar P. 
Published: September 2012

SUMMARYThis paper presents a possible new direction for the design of adaptive controllers. It begins by outlining a measurement‐based approach to the analysis, synthesis, and design of unknown systems. The systems under consideration can typically be electrical, mechanical, hydraulic, continuous, discrete, real, artificial, or biological, or of societal origin. Our approach is novel in the sense that we propose to use the measurement, or measured data, to directly design the control or decision variables whereas the current approach in the mainstream of system theory advocates that measured data be used to first identify the plant, and control design, or synthesis, then be based on the identified model. This latter approach has necessitated the creation of fields such as robust control and (indirect) adaptive control that try to account for errors in the identified model. Our approach, being data based, would potentially be automatically robust and adaptive. We show that such a measurement‐based approach is certainly feasible by considering DC circuits, AC circuits, block diagrams, and control systems. These results are then used to formulate the research problems for data‐based adaptive control. Copyright © 2012 John Wiley & Sons, Ltd.

Authors: Bordeaux Mélanie , Galarneau Anne , Drone Jullien 
Published: September 2012

AbstractEs besteht eine große Nachfrage nach selektiven Katalysatoren für die nachhaltige Oxidation von Alkanen, denn die in der Umwelt sehr häufig vorkommenden Alkane können dadurch in höherwertige Verbindungen, z. B. Chemikalien oder synthetische Brennstoffe, umgewandelt werden. Für diese – kinetisch gesehen – schwierige Reaktion wurde in den letzten Jahrzehnten eine Vielzahl von chemischen und biologischen Katalysatoren entwickelt, was einen Überblick über das Gebiet erschwert. Dieser Kurzaufsatz gibt zunächst eine Definition des idealen Katalysators für die Alkan‐Oxyfunktionalisierung und behandelt dann die heute verfügbaren Katalysatoren, die einem solchen idealen Katalysator am nächsten kommen.
Beyond Directing Groups: Transition‐Metal‐Catalyzed CH Activation of Simple Arenes
Authors: Kuhl Nadine , Hopkinson Matthew N. , Wencel‐Delord Joanna , Glorius Frank 
Published: September 2012

AbstractThe use of coordinating moieties as directing groups for the functionalization of aromatic CH bonds has become an established tool to enhance reactivity and induce regioselectivity. Nevertheless, with regard to the synthetic applicability of CH activation, there is a growing interest in transformations in which the directing group can be fully abandoned, thus allowing the direct functionalization of simple benzene derivatives. However, this approach requires the disclosure of new strategies to achieve reactivity and to control selectivity. In this review, recent advances in the emerging field of non‐chelate‐assisted CH activation are discussed, highlighting some of the most intriguing and inspiring examples of induction of reactivity and selectivity.

Published: September 2012

AbstractA terpolymer (POTVTh‐8FO‐DBT) containing fluorene, side chain conjugated thiophene and 4,7‐dithieny‐2,1,3‐benzothiadiazole was synthesized by palladium‐catalyzed Suzuki coupling method. The polymer is soluble in common organic solvents. The thermal, absorption, and electrochemical properties of the polymer were examined. Photovoltaic properties of POTVTh‐8FO‐DBT were studied by fabricating the polymer solar cells (PSCs) based on POTVTh‐8FO‐DBT as donor and [6,6]‐phenyl‐C61‐butyric acid methyl ester (PC61BM) as acceptor. With the weight ratio of POTVTh‐8FO‐DBT : PC61BM of 1 : 1 and the active layer thickness of 80 nm, the power conversion efficiency (PCE) of the device reached 0.47% with Voc = 0.61 V, Jsc = 1.61 mA/cm2, and filled factor (FF) = 0.49 under the illumination of AM 1.5, 100 mW/cm2. The results indicated that this polymer was promising donor candidates in the application of PSCs. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
Shape memory effect and properties memory effect of polyurethane
Authors: Farzaneh S. , Fitoussi J. , Lucas A. , Bocquet M. , Tcharkhtchi A. 
Published: September 2012

AbstractThe relationship between shape and properties memory effect, especially viscoelastic properties of polyurethane under study is the main aim of this research work. Tensile tests have been performed in order to introduce 100% of deformation in the polyurethane samples. Under this deformation, stress–relaxation experiments have been performed in order to eliminate the residual stresses. This deformation of the samples has been fixed by cooling. Recovery tests, then, were carried out at different isothermal temperatures that varied from 30°C to 60°C. Viscoelastic behavior has been studied by a biparabolic model and by using the Cole–Cole method. It was shown that this model describes the behavior of the polymer at the different states of shape memory tests. The constants of this model then have been determined. This study leads to a better understanding of the mechanism of shape memory effect. The comparison between the virgin polymer and the polymer after a recovery test by DMTA (dynamic mechanical thermal analysis) and by Cole–Cole method has illustrated that the polymer does not obtain its initial properties even when it was totally regained its initial shape. These results have been confirmed by three successive shape memory tests on the same sample and by comparing the mechanical characteristics of different cycles because “shape memory effect” and “properties memory effect” do not follow the same mechanisms. © 2012 Wiley Periodicals, Inc.

Finite‐Time Optimal Formation Control for Second‐Order Multiagent Systems
Authors: Liu Yongfang , Geng Zhiyong 
Published: September 2012

AbstractThis paper studies the problem of finite‐time optimal formation control for second‐order multiagent systems in situations where the formation time and/or the cost function need to be considered. The finite‐time optimal formation control laws are proposed for the cases with or without a leader, respectively. For the case of control being constrained, the time optimal formation problem is considered and an algorithm is designed to derive a feasible solution for the problem concerned. Although the feasible solution may not be optimal, it can provide a lower bound for time for the formation problem with control constraints. Once the given formation time is lower than this bound, the control constraints cannot be ensured. Finally, some numerical examples are given to illustrate the effectiveness of the theoretical results.
Interaction of oil sands tailings particles with polymers and microbial cells: First steps toward reclamation to soil
Authors: Voordouw Gerrit 
Published: September 2012

AbstractProduction of bitumen by surface mining of Alberta's oil sands has given rise to tailings ponds, containing large volumes of finely dispersed clays (108 m3), which settle only slowly. The mature fine tailings (MFT) in these ponds are operationally defined as consisting of particles smaller than 44 μm with a solids content in excess of 30% (w/w). Increasing the rate of densification of MFT is a rate‐limiting step in tailings pond reclamation. Accelerated densification has been achieved through mixing of MFT with sand in the presence of calcium sulfate as a binding agent to generate consolidated tailings. Addition of negatively charged polymer, together with either calcium or magnesium ions, is similarly effective. Although toxic to higher aquatic life, tailings ponds harbour a wide variety of mainly anaerobic microbes. These convert residual hydrocarbon, causing methane emissions of up to 104 m3 day−1. Interestingly, anaerobic microbial activity also accelerates tailings pond densification. Hence, many technologies designed to accelerate densification move tailings, at least conceptually, towards soil in which sand and clay particles are linked by large amounts of humic and fulvic acid polymers supporting large numbers of microbes in a mechanically stable structure. © 2012 Wiley Periodicals, Inc.

Chromatin structure outside and inside the nucleus
Authors: Ghirlando Rodolfo , Felsenfeld Gary 
Published: September 2012

AbstractThe structure of the 30‐nm chromatin fiber has provided, over the years, an important reference in chromatin studies. Originally derived from electron microscopic studies of soluble chromatin fibers released by restriction digestion, the gross structural features of such fragments have been supported by biophysical methods such as low angle X‐ray and neutron scattering, sedimentation, light scattering, and electric dichroism. Electron microscopy and sedimentation velocity measurements demonstrated that reconstituted chromatin fibers, prepared from repeating arrays of high affinity nucleosome positioning sequences, retain the same overall features as observed for native chromatin fibers. It had been suggested that the 30 nm fiber might be the form assumed in vivo by transcriptionally silent chromatin, but individual gene or genome‐wide studies of chromatin released from nuclei do not reveal any such simple correlation. Furthermore, even though the 30 nm fiber has been thought to represent an intermediate in the hierarchical folding of DNA into chromosomes, most analyses of chromatin folding within the nucleus do not detect any regular extended compact structures. However, there are important exceptions in chicken erythroid cell nuclei as well as in transcribed regions that form extended loops. Localized domains within the nucleus, either at the surface of chromosome domains or constrained as a specialized kind of constitutive heterochromatin by specific DNA binding proteins, may adopt 30 nm fiber‐like structures. © 2012 Wiley Periodicals, Inc.

Enhancing the Sensitivity of Aptameric Detection of Lysozyme with a “Feed‐Forward” Network of DNA‐Related Reaction Cycles
Authors: Ren Rui , Yu Zhaotao , Zou Yuanming , Zhang Shusheng 
Published: September 2012

AbstractIn this study, a network of DNA‐related reaction cycles was established to enhance the sensitivity of lysozyme detection with dual signal amplification, and aptamer‐based reactions were integrated into this system to provide high specificity. The network was organized in a feed‐forward manner: the “upstream cycles” recognized the lysozyme (the target) and released the “messenger strands” from probe A (a DNA construct); the “downstream cycles” received them and then released the “signal strands” from another DNA construct, probe B, in multiplied quantities to that of the original inputted lysozyme. The upstream cycles centered on “target‐displacement polymerization”, which circulates the lysozyme to provide primary amplification; the downstream cycles centered on “strand‐displacement polymerization”, which circulates the messenger strand to provide further amplification. There were also several “nicking–polymerization” cycles in both reaction groups that provide extra signal amplification. In total, the network enclosed eight interconnected and autonomic reaction cycles, with only two probes, two primers, and two enzymes needed as raw feeds, and the network can be operated simply in one‐pot mode. With this network, lysozyme could be quantified at lysozyme concentrations as low as 2.0×10−14 M, with a detection limit of 3.6×10−15 M (3σ rule), which was seven orders of magnitude lower than that obtained without any amplification(1.8×10−8 M). Detection of lysozyme in real serum samples confirmed the reliability and practicality of the assay based on this reported reaction network.
Revisiting the Molecular Roots of a Ubiquitously Successful Synthesis: Nickel(0) Nanoparticles by Reduction of [Ni(acetylacetonate)2]

Published: September 2012

AbstractThe widely used preparation of Ni0 nanoparticles from [Ni(acac)2] (acac=acetylacetonate) and oleylamine, often considered to be a thermolysis or a radical reaction, was analyzed anew by using a combination of DFT modeling and designed mechanistic experiments. Firstly, the reaction was followed up by using TGA to evaluate the energy barrier of the limiting step. Secondly, all the byproducts were identified using NMR spectroscopy, mass spectrometry, FTIR, and X‐ray crystallography. These methods allowed us to depict both main and side‐reaction pathways. Lastly, DFT modeling was utilized to assess the validity of this new scheme by identifying the limiting steps and evaluating the corresponding energy barriers. The oleylamine was shown to reduce the [Ni(acac)2] complex not through a one‐electron radical mechanism, as often stated, but as an hydride donor through a two‐electron chemical reduction route. This finding has strong consequences not only for the design of further nanoparticles syntheses that use long‐chain amine as a reactant, but also for advanced understanding of catalytic reactions for which these nanoparticles can be employed.

AbstractWe report herein a solvent‐free and microwaved‐assisted synthesis of several water soluble acyclic pentaheteroaryls containing 1,2,4‐oxadiazole moieties (1–7). Their binding interactions with DNA quadruplex structures were thoroughly investigated by FRET melting, fluorescent intercalator displacement assay (G4‐FID) and CD spectroscopy. Among the G‐quadruplexes considered, attention was focused on telomeric repeats together with the proto‐oncogenic c‐kit sequences and the c‐myc oncogene promoter. Compound 1, and to a lesser extent 2 and 5, preferentially stabilise an antiparallel structure of the telomeric DNA motif, and exhibit an opposite binding behaviour to structurally related polyoxazole (TOxaPy), and do not bind duplex DNA. The efficiency and selectivity of the binding process was remarkably controlled by the structure of the solubilising moieties.
