Published: July 2013

AbstractA potassium tungstate (K0.33WO3) nanosheet film grown directly on a conductive tungsten (W) substrate by a hotplate‐heating approach effects direct electron transfer between the W electrode and a biocatalytic protein or microbe, a long‐sought effect of both fundamental and practical importance. The K0.33WO3 forms into a 5–20 nm thick multilayered nanosheet with a number of steps along the surface. A single nanosheet of K0.33WO3 is hydrophilic and highly electron conducting (resistivity ∼8.3×10−3 Ω cm), characteristic of metallic behaviour. Glucose oxidase (GOD) immobilized on a K0.33WO3‐nanosheet‐coated electrode demonstrates facile direct electron transfer. The electron transfer rate constant (ks) is ∼9.5 s−1. This electrode has been used to construct a direct electrochemistry‐based glucose sensor, which exhibits good sensitivity (as high as ∼66.4 μA mM−1 cm−2), fast sensing response time (∼4 s), a low detection limit (0.5 μM), high selectivity and good reliability in practical uses. Growing K0.33WO3 nanosheet on electrodes offers a promising general approach for effecting direct bioelectrochemistry for widespread uses in bioelectronic and bioenergy applications.

Towards the Accurate and Efficient Calculation of Optical Rotatory Dispersion Using Augmented Minimal Basis Sets
Authors: Wiberg Kenneth B. , Caricato Marco , Wang Yi‐Gui , Vaccaro Patrick H. 
Published: July 2013

ABSTRACTIt has been recognized that quantum‐chemical predictions of dispersive (nonresonant) chiroptical phenomena are exquisitely sensitive to the periphery of the electronic wavefunction. To further elaborate and potentially exploit this assertion, linear‐response calculations of specific optical rotation were performed within the framework of density‐functional theory (DFT) by augmenting small basis sets (e.g., STO ‐ 3G and 3 ‐ 21G) for the core and valence electrons with diffuse functions taken from substantially larger bases (e.g., aug‐cc‐pVXZ where X = D, T, or Q). Of particular interest was the ability of such computationally efficient (augmented small‐basis) model chemistries to reproduce results derived from more expensive (canonical large‐basis) schemes. The results appear to be quite promising, with the augmented minimal‐basis ansatz often yielding wavelength‐resolved rotatory powers close to those deduced from standard DFT(B3LYP)/aug‐cc‐pVXZ treatments. Analogous linear‐response analyses were performed by means of coupled‐cluster singles and doubles (CCSD) theory, once again leading to augmented small‐basis estimates of specific rotation in reasonable accord with their large‐basis counterparts. Although CCSD predictions were deemed to be slightly worse than those obtained from DFT, they still were of sufficient quality for such reduced‐basis calculations to be considered viable for exploratory work.

Numerical evaluation of a one‐dimensional two‐fluid model applied to gas–solid cold‐flows in fluidised beds
Authors: Solsvik Jannike , Chao Zhongxi , Jakobsen Hugo A. 
Published: June 2013

AbstractComputational demanding two‐ and three‐dimensional two‐fluid models are frequently adopted simulating gas–solid flows in fluidised beds. Reduced computational cost is favourable for efficient numerical studies of technologies such as the novel chemical looping combustion (CLC), chemical looping reforming (CLR), and sorption‐enhanced steam methane reforming (SE‐SMR) processes. In this study, we elucidate the potential of a one‐dimensional two‐fluid model to describe gas–solid cold‐flows in fluidised beds. The validity of the numerical simulation results of the bubbling beds and risers have been compared to experimental data in the literature. Moreover, sensitivity analyses on drag closure laws and operation condition have been performed and a number of model solution techniques and algorithms are studied. In addition, simulation results of the one‐dimensional model are compared to results of a two‐dimensional model.For particular sets of operating conditions and flow characteristics, the one‐dimensional model compares fairly well to the simulation results of the two‐dimensional model and to experimental data. Under other operating conditions, large quantitative deviations can be observed. However, the one‐dimensional model is assumed to be sufficently accurate for particular reactor process optimisation and design evaluations.
Robust level control of a dry‐surge ore pile
Authors: McClure Kenneth Scott , Nagamune Ryozo , Marshman Devin , Chmelyk Terrance , Gopaluni Bhushan 
Published: June 2013

AbstractThis paper presents a new method for controlling the height of a mineral processing dry‐surge ore pile between specified upper and lower levels by manipulating the outlet ore flow. The upper level should not be exceeded for safety, while the height should always be higher than the lowest allowable level to maintain a reserve for continuous operation downstream of the ore pile. However, this is a non‐trivial control problem because the disturbance of the unpredictable discontinuous ore input must be attenuated in the continuous outlet ore flow. In addition, ore is mined from multiple sites and causes the physical properties of the ore to be uncertain. To deal with these issues, a control problem is formulated to attenuate the disturbance from the discontinuous feed and guarantee stability given the inaccurate process model. To solve the formulated control problem, a robust height controller is developed using the linear matrix inequality technique. It is shown that the robust controller attenuates four times more variability in outlet ore flow than a gain‐scheduled PI controller and guarantees robust closed loop stability.
Effects of hypoxia‐induced gill remodelling on the innervation and distribution of ionocytes in the gill of goldfish, Carassius auratus
Authors: Tzaneva Velislava , Vadeboncoeur Claudia , Ting Jaimee , Perry Steve F. 
Published: July 2013

ABSTRACTThe presence of an interlamellar cell mass (ILCM) on the gills of goldfish acclimated to 7°C leads to preferential distribution of branchial ionocytes to the distal edges of the ILCM, where they are likely to remain in contact with the water and hence remain functional. Upon exposure to hypoxia, the ILCM retracts, and the ionocytes become localized to the lamellar surfaces and on the filament epithelium, owing to their migration and the differentiation of new ionocytes from progenitor cells. Here we demonstrate that the majority of the ionocytes receive neuronal innervation, which led us to assess the consequences of ionocyte migration and differentiation during hypoxic gill remodelling on the pattern and extent of ionocyte neuronal innervation. Normoxic 7°C goldfish (ILCM present) possessed significantly greater numbers of ionocytes/mm2 (951.2 ± 94.3) than their 25°C conspecifics (ILCM absent; 363.1 ± 49.6) but a statistically lower percentage of innervated ionocytes (83.1% ± 1.0% compared with 87.8% ± 1.3%). After 1 week of exposure of goldfish to hypoxia, the pool of branchial ionocytes was composed largely of pre‐existing migrating cells (555.6 ± 38.1/mm2) and to a lesser extent newly formed ionocytes (226.7 ± 15.1/mm2). The percentage of new (relative to pre‐existing) ionocytes remained relatively constant (at ∼30%) after 1 or 2 weeks of normoxic recovery. After hypoxia, pre‐existing ionocytes expressed a greater percentage of innervation than newly formed ionocytes in all treatment groups; however, their percentage innervation steadily decreased over 2 weeks of normoxic recovery.

Snow cover and extreme winter warming events control flower abundance of some, but not all species in high arctic Svalbard
Authors: Semenchuk Philipp R. , Elberling Bo , Cooper Elisabeth J. 
Published: June 2013

AbstractThe High Arctic winter is expected to be altered through ongoing and future climate change. Winter precipitation and snow depth are projected to increase and melt out dates change accordingly. Also, snow cover and depth will play an important role in protecting plant canopy from increasingly more frequent extreme winter warming events. Flower production of many Arctic plants is dependent on melt out timing, since season length determines resource availability for flower preformation. We erected snow fences to increase snow depth and shorten growing season, and counted flowers of six species over 5 years, during which we experienced two extreme winter warming events. Most species were resistant to snow cover increase, but two species reduced flower abundance due to shortened growing seasons. Cassiope tetragona responded strongly with fewer flowers in deep snow regimes during years without extreme events, while Stellaria crassipes responded partly. Snow pack thickness determined whether winter warming events had an effect on flower abundance of some species. Warming events clearly reduced flower abundance in shallow but not in deep snow regimes of Cassiope tetragona, but only marginally for Dryas octopetala. However, the affected species were resilient and individuals did not experience any long term effects. In the case of short or cold summers, a subset of species suffered reduced reproductive success, which may affect future plant composition through possible cascading competition effects. Extreme winter warming events were shown to expose the canopy to cold winter air. The following summer most of the overwintering flower buds could not produce flowers. Thus reproductive success is reduced if this occurs in subsequent years. We conclude that snow depth influences flower abundance by altering season length and by protecting or exposing flower buds to cold winter air, but most species studied are resistant to changes.
Synthesis, Molecular and Photovoltaic Properties of an Indolo[3,2‐b]indole‐Based Acceptor–Donor–Acceptor Small Molecule
Authors: Lai Yu‐Ying , Yeh Jyun‐Ming , Tsai Che‐En , Cheng Yen‐Ju 
Published: July 2013

AbstractIndolo[3,2‐b]indole, containing two fused indole units, is an unexplored but promising electron‐rich molecule for constructing donor–acceptor materials due to its planar, symmetric, and extended conjugated structure. We have successfully developed a new synthetic pathway to prepare 2,7‐diboronic ester‐indolo[3,2‐b]indole, which was then reacted with dithienodiketopyrrolo‐pyrrole acceptor to afford a new acceptor–donor–acceptor (A–D–A) conjugated molecule, 2,7‐bis(dithienodiketopyrrolo‐pyrrole)indolo[3,2‐b]indole (2,7‐DPPIIDPP). II is used to stand for indolo[3,2‐b]indole in order to emphasize that this compound is constructed from two indole units. The A–D–A linkage through the 2,7‐positions of II not only preserves the phenylene units in the para‐conjugation but also renders stronger electron‐donating strength. This material exhibited good thermal stability, high crystallinity, and broad UV/Vis absorption. The solution‐processed bulk heterojunction device using the configuration of ITO/PEDOT:PSS/2,7‐DPPIIDPP:PC71BM/Ca/Al exhibited a Voc of 0.72 V, a Jsc of 6.88 mA/cm2, and an FF of 49.6 %, leading to a power conversion efficiency (PCE) of 2.45 %.
Matrix effect on the degradation of fragrant aldehydes: oxidation versus chlorination in an antiperspirant formulation
Authors: Ruyffelaere Fanny , Marteau Clémentine , Nardello‐Rataj Véronique , Favier Dominique , Vezin Hervé , Aubry Jean‐Marie 
Published: July 2013

ABSTRACTThe oxidative degradation of several fragrant aldehydes in an antiperspirant base has been investigated. The different products formed have been detected and identified by GC‐MS. It is shown that, besides the oxidation products, i.e. mainly the corresponding acid resulting from the Baeyer–Villiger reaction, several unexpected chlorinated products are formed through interactions with aluminium chlorhydrate and the suspension agent. The supposed intermediate in the chlorination pathway is the acyl hypochlorite R(CO)OCl which can react according to either an ionic or a radical route. Reactive species involved in these mechanisms are Clδ+ and Cl•, respectively. The common intermediate for the autoxidation and oxychlorination processes is the peracid R(CO)OOH.

A GUIDELINE FOR DEVELOPING AN INITIAL HYDROLOGICAL MONITORING NETWORK AS A BASIS FOR WATER MANAGEMENT IN ARTIFICIALLY DRAINED WETLANDS
Authors: Fahle Marcus , Dietrich Ottfried , Lischeid Gunnar 
Published: July 2013

ABSTRACTReliable hydrological monitoring is the basis for sound water management in drained wetlands. Since statistical methods cannot be employed for unobserved or sparsely monitored areas, the primary design (first set‐up) may be arbitrary in most instances. The objective of this paper is therefore to provide a guideline for designing the initial hydrological monitoring network. A scheme is developed that handles different parts of monitoring and hydrometry in wetlands, focusing on the positioning of surface water and groundwater gauges. For placement of the former, control units are used which correspond to areas whose water levels can be regulated separately. The latter are arranged depending on hydrological response units, defined by combinations of soil type and land use, and the chosen surface water monitoring sites. A practical application of the approach is shown for an investigation area in the Spreewald region in north‐east Germany. The presented scheme leaves a certain degree of freedom to its user, allowing the inclusion of expert knowledge or special concerns. Based on easily obtainable data, the developed hydrological network serves as a first step in the iterative procedure of monitoring network optimisation. Copyright © 2013 John Wiley & Sons, Ltd.

Published: July 2013

AbstractThe adoption of bi‐layered etch stop layer (BiESL) for oxide thin film transistor with high carrier mobility was proposed for the application to the large area high resolution AMOLED. A novel bi‐layered etch stop structure composed of Al2O3/SiO2, in which thin and dense Al2O3 film prepared by atomic layer deposition was deposited on the PECVD SiO2 layer. High mobility of In‐Ga‐Zn‐O TFT with the proposed BiESL showed no significant change in turn‐on voltage, even without passivation film. The field‐effect saturation mobility and sub‐threshold swing were measured as 29 cm2/V.s and 0.21 V/dec, respectively. Hydrogen doping during the PECVD SiNx passivation process can be effectively prevented by the introduction of Al2O3. Furthermore organic planarization film can be coated directly on top of the TFT array without causing any significant degradation of TFT performance.
6.4: Invited Paper: Impact of the Use of a Touch‐based Digital Reading Device in Immersive Reading
Authors: Shibata Hirohito , Takano Kentaro , Omura Kengo 
Published: July 2013

AbstractThis paper describes experiments to evaluate the impact of the use of a touch‐based digital reading device in immersive reading. The first experiment compared the performance of proofreading between that using paper documents and that using a touch‐based reading device. Results showed that participants detected more errors when reading from paper than when reading from the digital device. During reading, participants interacted with text such as pointing to words or brushing over sentences more frequently when reading from paper than when reading from the digital device. This suggests that interaction with text plays an important role in proofreading tasks. To verify this hypothesis, in the second experiment, participants proofread documents with constrained interaction with paper. Results showed that participants detected more errors when reading with text interaction than when reading without text interaction. Considering these results, we discuss practical implications to improve the usability of digital reading devices.
