Rapid bacteriophage MS2 transport in an oxic sandy aquifer in cold climate: Field experiments and modeling
Authors: Kvitsand Hanne M. L. , Ilyas Aamir , Østerhus Stein W. 
Published: November 2015

AbstractVirus removal during rapid transport in an unconfined, low‐temperature (6°C) sand and gravel aquifer was investigated at a riverbank field site, 25 km south of Trondheim in central Norway. The data from bacteriophage MS2 inactivation and transport experiments were applied in a two‐site kinetic transport model using HYDRUS‐1D, to evaluate the mechanisms of virus removal and whether these mechanisms were sufficient to protect the groundwater supplies. The results demonstrated that inactivation was negligible to the overall removal and that irreversible MS2 attachment to aquifer grains, coated with iron precipitates, played a dominant role in the removal of MS2; 4.1 log units of MS2 were removed by attachment during 38 m travel distance and less than 2 days residence time. Although the total removal was high, pathways capable of allowing virus migration at rapid velocities were present in the aquifer. The risk of rapid transport of viable viruses should be recognized, particularly for water supplies without permanent disinfection.
Ionic‐Liquid‐Based Polymer Electrolytes for Battery Applications

Published: November 2015

AbstractThe advent of solid‐state polymer electrolytes for application in lithium batteries took place more than four decades ago when the ability of polyethylene oxide (PEO) to dissolve suitable lithium salts was demonstrated. Since then, many modifications of this basic system have been proposed and tested, involving the addition of conventional, carbonate‐based electrolytes, low molecular weight polymers, ceramic fillers, and others. This Review focuses on ternary polymer electrolytes, that is, ion‐conducting systems consisting of a polymer incorporating two salts, one bearing the lithium cation and the other introducing additional anions capable of plasticizing the polymer chains. Assessing the state of the research field of solid‐state, ternary polymer electrolytes, while giving background on the whole field of polymer electrolytes, this Review is expected to stimulate new thoughts and ideas on the challenges and opportunities of lithium‐metal batteries.

Published: November 2015

AbstractA new class of stabilized pentacene derivatives with externally fused five‐membered rings are prepared by means of a key palladium‐catalyzed cyclopentannulation step. The target compounds are synthesized by chemical manipulation of a partially saturated 6,13‐dibromopentacene precursor that can be fully aromatized in a final step through a DDQ‐mediated dehydrogenation reaction (DDQ=2,3‐dichloro‐5,6‐dicyano‐1,4‐benzoquinone). The new 1,2,8,9‐tetraaryldicyclopenta[fg,qr]pentacene derivatives have narrow energy gaps of circa 1.2 eV and behave as strong electron acceptors with lowest unoccupied molecular orbital energies between −3.81 and −3.90 eV. Photodegradation studies reveal the new compounds are more photostable than 6,13‐bis(triisopropylsilylethynyl)pentacene (TIPS‐pentacene).
Improving the estimation of the true mean monthly and true mean annual air temperatures in Greece
Authors: Sakellariou N. K. , Kambezidis H. D. 
Published: November 2015

AbstractThe true mean monthly/annual air‐temperature estimations are usually based on the monthly averages of meteorological observations performed at standard hours. The performance of this combination varies as it depends on local climate of the particular meteorological station; it consequently allows for small/large deviations from its exact value. This study examines the possible deviations in Greece and suggests ways of improving the derived estimates. Two cases are considered. (1) An area has one thermograph and a number of thermometric stations. (2) An area has several thermographs and many thermometric stations. Solutions for minimizing the estimation error in both cases are provided.
Image‐based quantification of 3D morphology for bifurcations in the left coronary artery: Application to stent design

Published: November 2015

BackgroundImproved strategies for stent‐based treatment of coronary artery disease at bifurcations require a greater understanding of artery morphology.ObjectiveWe developed a workflow to quantify morphology in the left main coronary (LMCA), left anterior descending (LAD), and left circumflex (LCX) artery bifurcations.MethodsComputational models of each bifurcation were created for 55 patients using computed tomography images in 3D segmentation software. Metrics including cross‐sectional area, length, eccentricity, taper, curvature, planarity, branching law parameters, and bifurcation angles were assessed using open‐sources software and custom applications. Geometric characterization was performed by comparison of means, correlation, and linear discriminant analysis (LDA).ResultsDifferences between metrics suggest dedicated or multistent approaches should be tailored for each bifurcation. For example, the side branch of the LCX (i.e., obtuse marginal; OM) was longer than that of the LMCA (i.e., LCXprox) and LAD (i.e., first diagonal; D1). Bifurcation metrics for some locations (e.g., LMCA Finet ratio) provide results and confidence intervals agreeing with prior findings, while revised metric values are presented for others (e.g., LAD and LCX). LDA revealed several metrics that differentiate between artery locations (e.g., LMCA vs. D1, LMCA vs. OM, LADprox vs. D1, and LCXprox vs. D1).ConclusionsThese results provide a foundation for elucidating common parameters from healthy coronary arteries and could be leveraged in the future for treating diseased arteries. Collectively the current results may ultimately be used for design iterations that improve outcomes following implantation of future dedicated bifurcation stents. © 2015 Wiley Periodicals, Inc.
Rechargeable Metal–Air Proton‐Exchange Membrane Batteries for Renewable Energy Storage
Authors: Nagao Masahiro , Kobayashi Kazuyo , Yamamoto Yuta , Yamaguchi Togo , Oogushi Akihide , Hibino Takashi 
Published: November 2015

AbstractRechargeable proton‐exchange membrane batteries that employ organic chemical hydrides as hydrogen‐storage media have the potential to serve as next‐generation power sources; however, significant challenges remain regarding the improvement of the reversible hydrogen‐storage capacity. Here, we address this challenge through the use of metal‐ion redox couples as energy carriers for battery operation. Carbon, with a suitable degree of crystallinity and surface oxygenation, was used as an effective anode material for the metal redox reactions. A Sn0.9In0.1P2O7‐based electrolyte membrane allowed no crossover of vanadium ions through the membrane. The V4+/V3+, V3+/V2+, and Sn4+/Sn2+ redox reactions took place at a more positive potential than that for hydrogen reduction, so that undesired hydrogen production could be avoided. The resulting electrical capacity reached 306 and 258 mAh g−1 for VOSO4 and SnSO4, respectively, and remained at 76 and 91 % of their respective initial values after 50 cycles.

Development of the Travelling Wave Bioreactor. Part I: Design Studies Based on Numerical Models
Authors: Kaiser Stephan C. , Kraume Matthias , Eibl Dieter 
Published: November 2015

AbstractIn the travelling wave bioreactor (TWB) an orbital movement is used to set up a quasi‐periodic wave motion in the partially filled, toroidal shaped vessel. Based on computational fluid dynamics (CFD) models, this study presents detailed analyses of the fluid flow in the TWB for a wide range of operational conditions. Even though the wave propagation is shown to be greatly influenced by the rotation, it was found that the regular vessel shape facilitates a predominantly tangential flow with low back mixing, irrespective of the operational conditions. Hence, the influence of different bioreactor geometries without and with baffles is examined. The study indicates that CFD models can be used as a valuable tool for bioreactor development, because it provides a deep insight into the bioreactor's hydrodynamics and can help to reduce the number of prototypes.
Shape‐Controlled Preparation of Basic Bismuth Nitrate Crystals with High Iodide‐Removal Capacities
Authors: Ng Choon Hwee Bernard , Fan Wai Yip 
Published: November 2015

AbstractBismuth compounds have generated much interest as agents for the removal of radioactive iodine. In this work, we present the shape‐controlled preparation of basic bismuth nitrate crystals (BBN) in the form of Reuleaux triangles, hexagons, and deformed hexagon disks. Shape control was achieved through modulation of the effect of the shape‐directing agent 2,3‐bis(2‐pyridyl)pyrazine (dpp). The crystals were shown to be capable of iodide removal through reaction with I− to form BiOI. Depending on the degree of saturation, the resultant solids can exhibit colors ranging from yellow (unsaturated) to orange (saturated). Sedimentation of the products facilitates its removal after use. While the removal capacities did not depend on the crystal morphology, the Reuleaux triangle disks exhibited faster reaction rates than the other two shapes. With improved removal capacities of up to 3.6 mmol g−1, fast removal kinetics, good selectivity, and capture irreversibility, the BBN crystals show good potential as agents for radioactive iodine removal.
A Simple Approach towards Highly Dense Solvated Graphene Films for Supercapacitors
Authors: Sevilla Marta , Ferrero Guillermo A. , Vu Tan T. , Fuertes Antonio B. 
Published: November 2015

AbstractHighly dense porous solvated free‐standing graphene films were prepared by pressing graphene hydrogels obtained by a hydrothermal approach, which entails the generation of hematite nanoparticles that act as separators and endotemplate agents to generate pores. The as‐prepared solvated graphene films have characteristics that make them suitable for use in supercapacitors, that is, a free‐standing nature, a thickness of around 110 μm, a high packing density (1.1 g cm−3) and a large areal mass loading (12 mg cm−2). When used as supercapacitor electrodes, the graphene films show a high cell capacitance of ≈43 F g−1 (47 F cm−3) at 0.1 A g−1 in aqueous electrolyte (H2SO4) and retain 50 % of their low rate capacitance even at a high current density of 40 A g−1. Such porous yet highly dense materials could be used to fabricate lighter and more compact supercapacitor devices than those currently based on activated carbon.
