Development of Film Sensors Based on Conjugated Polymers for Copper (II) Ion Detection
Authors: Lv Fengting , Feng Xuli , Tang Hongwei , Liu Libing , Yang Qiong , Wang Shu 
Published: January 2011

AbstractA fluorescent film sensor was prepared by chemical modification of a polyfluorene derivative on a glass‐plate surface. X‐ray photoelectron spectroscopy and ellipsometry measurements demonstrate the covalent attachment of the polyfluorene derivative to the glass‐plate surface. The sensor was used to detect Cu2+ions in aqueous solution by a mechanism exploiting fluorescence quenching of conjugated polymers. Among the tested metal ions, the film sensor presents good selectivity towards Cu2+ions. Further experiments show that the sensing process is reversible. Moreover, sensory microarrays based on conjugated polymers targeting Cu2+ions are constructed, which display similar sensing performance to that of the film sensor. The structural motif in which conjugated polymers are covalently confined to a solid substrate surface offers several attractive advantages for sensing applications. First, in comparison with film sensors in which small fluorescent molecules are employed as sensing elements, the sensitivity of our new film sensor is enhanced due to the signal‐amplifying effect of the conjugated polymers. Second, the film sensors or microarrays can be used in aqueous environments, which is crucial for their potential use in a wide range of real‐world systems. Since the sensing process is reversible, the sensing materials can be reused. Third, unlike physically coated polymer chains, the covalent attachment of the grafted chains onto a material surface precludes desorption and imparts long‐term stability of the polymer chains.

Authors: Ma Jing , Hu Jiamian , Li Zheng , Nan Ce‐Wen 
Published: January 2011

AbstractMultiferroic magnetoelectric composite systems such as ferromagnetic‐ferroelectric heterostructures have recently attracted an ever‐increasing interest and provoked a great number of research activities, driven by profound physics from coupling between ferroelectric and magnetic orders, as well as potential applications in novel multifunctional devices, such as sensors, transducers, memories, and spintronics. In this Review, we try to summarize what remarkable progress in multiferroic magnetoelectric composite systems has been achieved in most recent few years, with emphasis on thin films; and to describe unsolved issues and new device applications which can be controlled both electrically and magnetically.
Major Renewal of the Editorial and Advisory Boards as Advanced Synthesis & Catalysis Begins its 2nd Decade
Authors: Richmond Joe P. 
Published: January 2011

AbstractAs Advanced Synthesis & Catalysis enters its second decade, Chris H. Senanayake and Qilin Zhou join the ASC Editorial Board, chaired by Ryoji Noyori. A turnover on the ASC Advisory Boards was also needed, in order that the journal remain fresh and innovative. Therefore after 10 years, there has been a renewal of over half of the members of the ASC Industrial and Academic Advisory Boards. The new members are top chemists in the younger generation, who promise to be the pioneers and leaders of the next decade. In its first decade, ASC has had a steady increase in printed pages and in impact; it is still on the upward slope of it life curve. It is the goal of the new Editorial and Advisory Boards, and a strengthened Editorial Office, to maintain the journal′s position of leadership by continuing to be a prestigious address for the publication of the seminal work in the field of (green) synthesis and catalysis.
Development of a new technique to generate microcapsules from the breakup of non‐Newtonian highly viscous fluid jets
Authors: Rodríguez‐Rivero C. , Del Valle E. M. M. , Galán M. A. 
Published: January 2011

AbstractA new method to produce microcapsules ranging from 300 to 700 μm based on the droplets formation from non‐newtonian high viscous liquids has been developed, characterized, and modeled. The technique involves the generation of a continuous high viscous solution jet, which is destabilized by means of a controlled vibration, breaking into droplets that undergo stabilization through a gelling process. Finally, the application of the wave‐mechanisms‐based theory to obtain a set of equations for the fitting of experimental data is assessed, as a first approximation for a better knowledge of the process. To find the fitting equations, the influence on the microcapsules size is studied through two‐dimensionless groups, the Ohnesorge and the Weber numbers, involving the liquid viscosity and flow, respectively, and determining their exponential dependences. Further coefficients are obtained by least‐squares fit of the experimental data. © 2011 American Institute of Chemical Engineers AIChE J, 2011
Getting biofuels on the green and narrow path: why we must get advanced biofuels started and started in the right way
Authors: Greene Nathanael 
Published: January 2011

AbstractWe need every tool we can get our hands on in the fight against global warming; a truly low‐carbon liquid fuel is clearly a tool we cannot give up lightly and arguably a tool we cannot do without. Unfortunately, our current policies do not require or reward broadly sustainably and truly low‐carbon biomass. What's more, the small policy steps forward are under atttack and the comprehensive policy solutions are not even being debated. As a result, any supply estimate that does not start by identifying the policies that would guide the market to choose sustainably managed feedstocks in sustainable quantities can be nothing more than a proof of concept, technical assessment. These estimates are misleadingly high in the current policy climate. Nevertheless to stop global warming we must try to get the right policies in place and with an aggressive package of policies, they might actually turn out to be low. A modest proposal for a billion gallon challenge with rich incentives and rigorous environmental requirements (perhaps building of voluntary sustainability certification standards such as the Roundtable on Sustainable Biofuels) is offered as a way to launch the advanced biofuels industry on the right track in a way will build public support.
High‐performance prediction of functional residues in proteins with machine learning and computed input features
Authors: Somarowthu Srinivas , Yang Huyuan , Hildebrand David G.C. , Ondrechen Mary Jo 
Published: January 2011

AbstractOne of the major challenges in genomics is to understand the function of gene products from their 3D structures. Computational methods are needed for the high‐throughput prediction of the function of proteins from their 3D structure. Methods that identify active sites are important for understanding and annotating the function of proteins. Traditional methods exploiting either sequence similarity or structural similarity can be unreliable and cannot be applied to proteins with novel folds or low homology with other proteins. Here, we present a machine‐learning application that combines computed electrostatic, evolutionary, and pocket geometric information for high‐performance prediction of catalytic residues. Input features consist of our structure‐based theoretical microscopic anomalous titration curve shapes (THEMATICS) electrostatics data, enhanced with sequence‐based phylogenetic information from INTREPID and topological pocket information from ConCavity. Our THEMATICS‐based input features are augmented with an additional metric, the theoretical buffer range. With the integration of the three different types of input, each of which performs admirably on its own, significantly better performance is achieved than that of any of these methods by itself. This combined method achieves 86.7%, 92.5%, and 93.8% recall of annotated functional residues at 5, 8, and 10% false‐positive rates, respectively. © 2011 Wiley Periodicals, Inc.

A delay‐oriented prioritization policy based on non‐congestive queuing
Authors: Papastergiou G. , Georgiou C. , Mamatas L. , Tsaoussidis V. 
Published: January 2011

AbstractIn this paper, we depart from our previously proposed Non‐Congestive Queuing (NCQ) mechanism and propose a new scheduling discipline that allows for efficient interoperation of dedicated systems (such as sensor and voice networks) with the Internet. More precisely, our approach provides delay guarantees to applications that do not contribute noticeably to congestion because of their tiny packet sizes and low transmission rates. In addition, our approach uses a second level of prioritization that conditionally favors, in terms of delay, applications with slightly longer packets as well. Based on the NCQ concept, Non‐Congestive Queuing Plus (NCQ+) promotes applications that require comparatively small service times, as long as their total service times cause insignificant delays to other packets in the queue. Therefore, we prioritize packets, and in turn corresponding flows, according to their impact on total delay. We evaluate NCQ+ using ns‐2‐based experiments. Results show that whenever prioritization buffer resources are sufficient, NCQ+ can provide non‐detectable delays to sensor applications and conditionally improve the performance of VoIP applications, while maintaining the impact on the performance of the other flows insignificant.

Published: January 2011

AbstractNeurons are functionally and morphologically polarized and possess two distinct types of neurites: axons and dendrites. Key molecules for axon formation are transported along microtubules and accumulated at the distal end of the nascent axons. In this review, we summarize recent advances in the understanding of the mechanisms involved in selective transport in neurons. In addition, we focus on motor proteins, cargo, cargo adaptors, and the loading and unloading of cargo. © 2011 Wiley Periodicals, Inc. Develop Neurobiol 71: 445–457, 2011
