One‐Pot Solvothermal Synthesis of TiO2 Nanobelt/Graphene Composites for Selective Renal Cancer Cells Destruction
Authors: Cheng Jinsheng , Wan Weihong , Zhu Wenjuan 
Published: August 2015

AbstractLittle attention has been paid to synthesis and application of TiO2 nanobelt/grapheme composites (TiO2/GR). In this work, a facile one‐pot solvothermal approach to synthesize TiO2/GR was developed. In such processes, the reduction of graphene oxide (GO) nanosheets was accompanied by generation of TiO2/GR in one‐step. In vitro experiments revealed that the renal cancer (RENCA) cell viability decreased sharply to 4.72% in the presence of the resulting composites in the near infrared light (NIR) window.
Image‐based estimation method for field inhomogeneity in brain echo‐planar images with geometric distortion using k‐space textures
Authors: Kumazawa Seiji , Yoshiura Takashi , Honda Hiroshi 
Published: August 2015

ABSTRACTEcho‐planar imaging (EPI) can suffer from geometrical distortion due to magnetic field inhomogeneity. To correct the geometric distortions in EPI, a magnetic field map is used. Our purpose was to develop a novel image‐based method for estimating the field inhomogeneity map from the distorted EPI image and T1‐weighted image of the brain using k‐space textures. Based on magnetic resonance imaging physics, our method synthesizes the distorted image to match the measured EPI image through the generating process of EPI image by updating the estimated field inhomogeneity map. The estimation process was performed to minimize the cost function, which was defined by the synthesized EPI image and the measured EPI image with geometric distortion, using an iterative conjugate gradient algorithm. The proposed method was applied to simulation and human data. To evaluate the performance of the proposed method quantitatively, we used the normalized root mean square error (NRMSE) between the ground truth and the results estimated by our proposed method. In simulation data, the values of the NRMSE between the ground truth and the estimated field inhomogeneity map were <0.08. In both simulation and human data, the estimated EPI images were very similar to input EPI images, and the NRMSE values between them were <0.09. The results of the simulated and human data demonstrated that our method produced a reasonable estimation of the field inhomogeneity map. The estimated map could be used for distortion correction in EPI images. © 2015 Wiley Periodicals, Inc. Concepts Magn Reson Part B (Magn Reson Engineering) 45B: 142–152, 2015
Hierarchical MoSe2 Nanosheets/Reduced Graphene Oxide Composites as Anodes for Lithium‐Ion and Sodium‐Ion Batteries with Enhanced Electrochemical Performance
Authors: Zhang Zhian , Fu Yun , Yang Xing , Qu Yaohui , Zhang Zhiyong 
Published: August 2015

AbstractThe preparation and electrochemical storage behavior of hierarchical MoSe2/reduced graphene oxide (rGO) composites were studied. The preparation was achieved by a facile hydrothermal route. The results show that MoSe2 has a high capacity for lithium ion and sodium ion storage and that the incorporation of rGO has further improved the electrochemical property of MoSe2 effectively. As anode materials for lithium‐ion and sodium‐ion batteries, the MoSe2/rGO composites demonstrate excellent rate performance and cycling stability of 917 mA h g−1 after 100 cycles for Li+ storage and 430 mA h g−1 after 200 cycles for Na+ storage at a current density of 0.5 A g−1, which is attributed to the robust hierarchical structure and the synergistic effects between MoSe2 nanosheets and rGO. Therefore, the electrochemical evaluations suggest that the obtained hierarchical structure MoSe2/rGO composites hold great potential as anode materials for lithium‐ion and sodium‐ion batteries.
Identification of Core Segment of Amyloidal Peptide Mediated by Chaperone Molecules by using Scanning Tunneling Microscopy
Authors: Yu Yue , Yang Yanlian , Wang Chen 
Published: August 2015

AbstractWe illustrate in this work that pristine assemblies of amyloidal peptides can be obtained by perturbations of reduced scanning bias, and show a broad distribution in peptide length. In contrast, the chaperone‐mediated peptide co‐assembly presents ordered lamellar structures with a homogeneous distribution in length, which could be attributed to the core segment of the peptide. The efforts are beneficial for gaining insight into the aggregation propensity of peptides and inter‐peptide interactions.
Rationally Designed Supramolecular Organic Hosts for Benzo[a]pyrene Binding and Detection
Authors: Radaram Bhasker , Levine Mindy 
Published: August 2015

AbstractA series of electronically dissymmetric all‐organic macrocycles were synthesized using straightforward synthetic procedures. These macrocycles vary in the nature of the substituents, the geometry of the linkage that connects the electron‐deficient aromatic ring, the type of linkage, and the presence or absence of a heteroaromatic ring. These small structural variations impart significant differences in the performance of these macrocycles in binding benzo[a]pyrene, with binding constants up to 2.5 × 104 M–1 obtained. They also lead to significant differences in their ability to promote non‐covalent energy transfer from benzo[a]pyrene to a BODIPY fluorophore, with energy transfer efficiencies ranging from 32 % to 398 %. These differences can be explained using a variety of computational investigative techniques, which highlight the flexibility of the macrocycle architectures to accommodate benzo[a]pyrene and to promote close donor–acceptor interactions.
Memory distortion and attitude change—Two routes to cognitive balance
Authors: Berthold Anne , Blank Hartmut 
Published: August 2015

AbstractWe report novel research investigating memory distortion as an alternative route to cognitive balance, comparing it with attitude change as a well‐known balancing mechanism. Participants received statements from multiple communicators about a controversial topic (national pride in Study 1 and climate protection in Study 2) and remembered these statements immediately or 1 week later. This resulted in initially balanced or unbalanced combinations of the liking for individual communicators and the communicators' statements and in subsequent balance increases due to liking change or misremembering of statements. The contribution of memory distortion to balance was significant but weaker and less efficient than that of liking change, and the contributions were empirically independent (i.e., uncorrelated and differentially related to third variables—specifically, memory strength and individual cognitive consistency motivation). They also had a different temporal trajectory (liking change fast and memory distortion slow). We discuss theoretical and practical implications.
Recent Advances in Nanomaterial‐Modified Pencil Graphite Electrodes for Electroanalysis
Authors: Akanda Md. Rajibul , Sohail Manzar , Aziz Md. Abdul , Kawde Abdel‐Nasser 
Published: August 2015

AbstractPencil graphite electrodes (PGEs) have several advantages over other carbon‐based or commercial metal electrodes, including widespread availability, very low cost, and ease of modification. To make the best use of PGEs in electroanalysis, significant recent advances in the development of different nanomaterial‐PGEs have been observed. The literature published up to mid‐2015 is summarized in the present review, with a focus on the various methodologies used to readily modify graphite pencil electrodes using nanomaterials. This review also touches on the surface characterization of these electrodes and their potential applications in a variety of electrochemical detection applications. The review outlines the scope for further research in this area and discusses the importance of surface modifications of conventional PGE electrodes using nanomaterials or a combination of nanomaterials and electroactive polymers.
Production and Hedging Under Smooth Ambiguity Preferences
Authors: Wong Kit Pong 
Published: August 2015

AbstractThis paper examines the optimal production and hedging decisions of the competitive firm facing ambiguous price and background risk. Ambiguity is modeled by a second‐order probability distribution that captures the firm's uncertainty about which of the subjective beliefs govern the price and background risk. Ambiguity preferences are modeled by the (second‐order) expectation of a concave transformation of the (first‐order) expected utility of profit conditional on each plausible subjective joint distribution of the price and background risk. When the background risk is additive in nature, we show that the separation theorem holds in that the firm's optimal production decision depends neither on the firm's attitude toward ambiguity nor on the incident of the underlying ambiguity. We derive necessary and sufficient conditions under which the firm's optimal forward position is completely characterized. When the background risk is multiplicative in nature, we derive sufficient conditions under which the firm reduces its optimal output level and opts for an under‐hedge. Contrary to the conventional wisdom, we show that the behavior of the firm is affected by the introduction of ambiguity even when the firm is ambiguity neutral. © 2015 Wiley Periodicals, Inc.
