Strong enhancement of 10–100 keV electron fluxes by combined effects of chorus waves and time domain structures
Authors: Ma Qianli , Mourenas Didier , Artemyev Anton , Li Wen , Thorne Richard M. , Bortnik Jacob 
Published: May 2016

AbstractTime domain structures (TDSs) are trains of intense electric field spikes observed in large numbers during plasma injections in the outer radiation belt. Here we explore the question of their importance in energetic electron acceleration and loss in this region. Although the most common TDSs can preaccelerate low‐energy electrons up to 1–5 keV energies, they often cannot produce by themselves the seed population of 30–150 keV electrons, which are needed for a subsequent energization up to relativistic energies during storms or substorms. However, we demonstrate by numerical simulations that modifications of the low‐energy electron pitch angle and energy distributions due to interactions with TDS lead to more efficient scattering of electrons by chorus waves toward both higher and lower pitch angles, ultimately leading to both significantly higher fluxes in the 10–100 keV energy range and more intense 1–100 keV precipitation into the atmosphere, potentially affecting the outer radiation belt dynamics.
Einzelnachweis und elektrochemisch unterstützte Identifizierung adsorbierter Nanopartikel mit Oberflächenplasmonen‐Mikroskopie
Authors: Nizamov Shavkat , Kasian Olga , Mirsky Vladimir M. 
Published: May 2016

AbstractDie zunehmende Produktion und Verwendung von Nanopartikeln erfordert eine höchst empfindliche analytische Methode für die Quantifizierung und Identifizierung dieser potenziell gefährlichen Materialien. Hier beschreiben wir eine Anwendung der Oberflächenplasmonen‐Mikroskopie für den Einzelnachweis jedes einzelnen adsorbierten Nanopartikels und die Sichtbarmachung seiner elektrochemischen Umsetzung. Während die Adsorptionsgeschwindigkeit die Mengenkonzentration der Nanopartikel charakterisiert, bestimmt das Oxidationspotential, bei dem die adsorbierten Nanopartikel optisch verschwinden, die Art ihres Materials. Alle adsorbierten Nanopartikel unterliegen zeitgleich dem Potentialvorschub, werden aber mithilfe ihres elektrochemischen Auflösungspotentials von einem einzelnen bis zu einer Million adsorbierter Partikel individuell identifiziert. Mit dieser Technik wurden Silber‐ und Kupfernanopartikel untersucht, sie kann aber auch auf viele andere elektrochemisch aktive Nanopartikel übertragen werden.
Direct Fabrication of Free‐Standing MOF Superstructures with Desired Shapes by Micro‐Confined Interfacial Synthesis
Authors: Kim Jin‐Oh , Min Kyoung‐Ik , Noh Hyunwoo , Kim Dong‐Hwi , Park Soo‐Young , Kim Dong‐Pyo 
Published: May 2016

AbstractRecently, metal–organic frameworks (MOFs) with multifunctional pore chemistry have been intensively investigated for positioning the desired morphology at specific locations onto substrates for manufacturing devices. Herein, we develop a micro‐confined interfacial synthesis (MIS) approach for fabrication of a variety of free‐standing MOF superstructures with desired shapes. This approach for engineering MOFs provides three key features: 1) in situ synthesis of various free‐standing MOF superstructures with controlled compositions, shape, and thickness using a mold membrane; 2) adding magnetic functionality into MOF superstructures by loading with Fe3O4nanoparticles; 3) transferring the synthesized MOF superstructural array on to flat or curved surface of various substrates. The MIS route with versatile potential opens the door for a number of new perspectives in various applications.
A highly active and selective β‐nucleating agent for isotactic polypropylene and crystallization behavior of β‐nucleated isotactic polypropylene under rapid cooling
Authors: Zhao Shicheng , Gong Hanzhang , Yu Xin , Xin Zhong , Sun Shibao , Zhou Shuai , Shi Yaoqi 
Published: May 2016

ABSTRACTZinc adipate (Adi‐Zn) was observed to be a highly active and selective β‐nucleating agent for isotactic polypropylene (iPP). The effects of Adi‐Zn on the mechanical properties and the β‐crystals content of nucleated iPP were investigated. The impact strength of iPP nucleated with 0.2 wt % Adi‐Zn was 1.8 times higher than that of neat iPP. In addition, wide‐angle X‐ray diffraction analysis indicated that the content of β‐crystals in nucleated iPP (kβ value) reached 0.973 with 0.1 wt % Adi‐Zn, indicating that Adi‐Zn is a highly active and selective β‐nucleating agent for iPP. Furthermore, fast scanning chip calorimetry (FSC) studies using cooling rates from 60 to 13,800 °C min−1 revealed that the formation of β‐crystals significantly depended on the cooling rates. At cooling rates below 3000 °C min−1, only β‐crystals existed. However, at cooling rates above 6000 °C min−1, β‐crystals failed to form. Moreover, a lower critical crystallization temperature that corresponded to the generation of β‐crystals was investigated using cooling‐induced crystallization, and the results are in good agreement with those of a previous study. © 2016 Wiley Periodicals, Inc.

An Efficient Visible and Near‐Infrared (NIR) Emitting SmIII Metal–Organic Framework (Sm‐MOF) Sensitized by Excited‐State Intramolecular Proton Transfer (ESIPT) Ligand
Authors: Chen Ling , Zhang Hao , Pan Mei , Wei Zhang‐Wen , Wang Hai‐Ping , Fan Ya‐Nan , Su Cheng‐Yong 
Published: May 2016

AbstractWe report herein an unprecedented example of a luminescent SmIII metal–organic framework (Sm‐MOF), in which both the visible and near‐infrared (NIR) emissions of Sm3+ ions are able to be sensitized by an excited‐state intramolecular proton transfer (ESIPT) ligand. Due to the solvent‐mediated interchange between enol and keto excited states of the ligand and subsequent energy transfer rate to Sm3+ ions, the luminescent decay lifetime of the Sm‐MOF can be tuned in different solvent‐grinding systems.
A Dual‐Process Diffusion Model
Authors: Alós‐Ferrer Carlos 
Published: May 2016

AbstractThis paper presents a simple formal analytical model delivering qualitative predictions for response times in binary‐choice experiments. It combines a dual‐process/multi‐strategy approach with the standard diffusion model, modeling a utility decision process and a heuristic decision process as diffusion processes of evidence accumulation. For experiments with objective alternatives (including many tasks in judgment and decision making), the model predicts that errors will be quicker than correct responses in case of process conflict and slower in case of alignment, capturing a well‐documented asymmetry regarding slow or fast errors. Further, the model also predicts that correct responses are slower in case of conflict than in case of alignment, capturing the well‐known Stroop effect. The model is also extended to cover experiments with subjective alternative evaluations, that is, preferential choice. In this case, results depend on whether trials are hard or easy, that is, on whether the heuristic can be interpreted as relatively automatic or not. Copyright © 2016 John Wiley & Sons, Ltd.
Progressive light volume for interactive volumetric illumination
Authors: Liu Ning , Zhu Dengming , Wang Zhaoqi , Wei Yi , Shi Min 
Published: May 2016

AbstractWe propose a technique named progressive light volume to support advanced volumetric illumination effects, such as single scattering and multi scattering. The light volume stores direct lighting information for sample points of the volume data. Using the light volume, we are able to compute the direct lighting for any point in the volume data with a single texture lookup. In order to keep the rendering at an interactive frame rate, we build the light volume progressively if necessary. During the light volume construction period, we use a fast ray casting algorithm to produce a rough rendering estimate from the light volume. After the light volume is built, we use a path tracer to continuously estimate the light intensity for each pixel. Our method puts no restrictions on the number, position, and type of lights. We conducted a comprehensive evaluation for various datasets. The rendering results show that our method is able to produce compelling images, and the performance results indicate that our method is practical for interactive use.

Density‐enhanced perceptual mosaic on GPU
Authors: Li Ping , Sun Hanqiu 
Published: May 2016

AbstractImage mosaic effects are wildly applied in print media, domestic decoration, and many image beautification applications. However, the current image mosaic methods are mostly based on fixed‐size image tiles, simple color adjustment, and irregular image segmentation, which are inaccurate and very time‐consuming. In this paper, we present a graphics processing unit‐accelerated perceptual mosaic using density tiles replacement and brightness lighting optimization, keeping original image structure details and providing more expressive visual effects. Automatic density replacement map segmentation and color‐based region tiles replacement are performed to facilitate the mosaic. Delicate brightness optimization and perceptual color correction are further applied to enhance expressive lighting effects. We also consider the salience perception of images and similarity correlation among neighboring tiles for our perceptual mosaic. The experimental results have shown the efficiency and high‐quality performance of our density‐enhanced perceptual mosaic on graphics processing unit. Copyright © 2016 John Wiley & Sons, Ltd.
Ammonium Feeding and pH Influencing Arthrospira platensis Growth, Composition, and C‐ and N‐Uptake
Authors: Rodrigues Mayla S. , Ferreira‐Camargo Lívia S. , Converti Attilio , Sato Sunao , Carvalho João Carlos M. 
Published: May 2016

AbstractArthrospira (Spirulina) platensis was cultivated in bench‐scale open ponds on a modified Schlösser medium. The fed‐batch exponential supply of ammonium sulfate at defined feeding time and pH allowed obtaining optimum results in terms of biomass growth and composition. The cultivation conditions established herein will constitute the main starting point of a wider study in which this cyanobacterium is employed for fixation of CO2 from industrial plants. The industrial exploitation of these results appears to be promising also for single‐cell protein production.
Strong and Reversible Circularly Polarized Luminescence Emission of a Chiral 1,8‐Naphthalimide Fluorophore Induced by Excimer Emission and Orderly Aggregation
Authors: Sheng Yuan , Ma Jing , Liu Shuai , Wang Yuxiang , Zhu Chengjian , Cheng Yixiang 
Published: May 2016

AbstractFour chiral 1,2‐diaminocyclohexane (DACH)‐based molecules (R,R/S,S‐2 and R,R/S,S‐4) incorporating 1,8‐naphthalimide fluorophores exhibit strong circularly polarized luminescence (CPL) emission signals in common organic solvents. Interestingly, the reversed CPL signals can be observed in the aggregated state, which is due to the orderly aggregation.
Stereoselective Synthesis and Retentive Trapping of α‐Chiral Secondary Alkyllithiums Leading to Stereodefined α,β‐Dimethyl Carboxylic Esters
Authors: Morozova Varvara , Moriya Kohei , Mayer Peter , Knochel Paul 
Published: May 2016

AbstractThe treatment of α‐chiral secondary alkyl iodides with tBuLi at −100 °C leads to the corresponding secondary alkyllithiums with high retention of configuration. Subsequent quenching with various electrophiles such as Bu2S2, DMF, MeOB(OR)2, or Et2CO provides the desired products with retention of configuration. Furthermore, a transmetalation with CuBr⋅P(OEt)3 also allows retentive trapping with acid chlorides and ethylene oxide. The quenching of the resulting alkyllithiums with ClCO2Et furnishes stereoselectively syn‐ and anti‐ethyl‐2,3‐dimethyl ester carboxylates (d.r.>94 %). Related esters bearing three adjacent stereo‐controlled centers (stereotriads) have also been prepared. This method has been applied to the synthesis of the ant pheromone (±)‐lasiol in 26 % overall yield (four steps) with d.r.=97:3 starting from commercially available cis‐2,3‐epoxybutane.
