Interactions between journal attributes and authors' willingness to wait for editorial decisions
Authors: Rousseau Sandra , Rousseau Ronald 
Published: March 2012

In this article, we report on a discrete choice experiment to determine the willingness‐to‐wait (WTW) in the context of journal submissions. Respondents to our survey are mostly active in the information sciences, including librarians. Besides WTW, other attributes included in the study are the quality of the editorial board, the quality of referee reports, the probability of being accepted, the ISI impact factor, and the standing of the journal among peers. Interaction effects originating from scientists' personal characteristics (age, region of origin, motivations to publish) with the WTW are highlighted. A difference was made between submitting a high quality article and a standard article.Among the interesting results obtained from our analysis we mention that for a high‐quality article, researchers are willing to wait some 18 months longer for a journal with an ISI impact factor above 2 than for a journal without an impact factor, keeping all other factors constant. For a standard article, the WTW decreases to some 8 months. Gender had no effect on our conclusions.

Published: March 2012

AbstractThe inverse‐micellar preparation of Si nanoparticles (Nps) was improved by utilizing sodium naphthalide. The Si Nps were subsequently functionalized with 4‐vinylbenzoic acid for their attachment onto TiO2 films of dye‐sensitized solar cells (DSSCs). The average diameter of the COOH‐functionalized Si (SiCOOH) Nps was 4.6(±1.7) nm. Depth profiling by secondary‐ion mass spectrometry revealed that the Si Nps were uniformly attached onto the TiO2 films. The number of RuII dye molecules adsorbed onto a TiO2 film that was treated with the SiCOOH Nps was 42 % higher than that on the untreated TiO2 film. As a result, DSSCs that incorporated the SiCOOH Nps exhibited higher short‐circuit photocurrent density and an overall energy‐conversion efficiency than the untreated DSSCs by 22 % and 27 %, respectively. This enhanced performance, mostly owing to the intramolecular charge‐transfer to TiO2 from the dye molecules that were anchored to the SiCOOH Nps, was confirmed by comparing the performance with two different RuII–bipyridine dyes (N719 and N749).
Advances in Copper‐Catalyzed CC Coupling Reactions and Related Domino Reactions Based on Active Methylene Compounds
Authors: Liu Yunyun , Wan Jie‐Ping 
Published: March 2012

AbstractActive methylene compounds are a major class of reaction partners for CC bond formation with sp2 CX (X=halide) fragments. As one of the most‐classical versions of the Ullmann‐type coupling reaction, activated‐methylene‐based CC coupling reactions have been efficiently employed in a large number of syntheses. Although this type of reaction has long relied on noble‐metal catalysis, the renaissance of copper catalysis at the end of last century has led to dramatic developments in Ullmann CC coupling reactions. Owing to its low cost, abundance, as well as excellent catalytic activity, the exceptional atom economy of copper catalysis is gaining widespread attention in various organic synthesis. This review summarizes the advances in copper‐catalyzed intermolecular and intramolecular CC coupling reactions that use activated methylene species as well as in tandem reactions that are initiated by this transformation.

Published: March 2012

AbstractWe have designed an ambipolar material, 3,7‐bis[4‐(N‐carbazolyl)‐phenyl]‐2,6‐diphenylbenzo[1,2‐b:4,5‐b′]difuran (CZBDF), and synthesized it by zinc‐mediated double cyclization. Its physical properties clarified that CZBDF possesses a wide‐gap character, well‐balanced and high hole and electron mobilities of larger than 10−3 cm2 V−1 s−1, and a high thermal stability. Using CZBDF as a host material for heterojunction OLED devices, a full range of visible emission was obtained. Notably, CZBDF also enabled us to fabricate RGB‐emitting homojunction OLEDs, with performances comparable or superior to the heterojunction devices composed of several materials.
Highly Hydrophilic Copolymers of N,N‐Dimethylacrylamide, Acrylamido‐2‐methylpropanesulfonic acid, and Ethylenedimethacrylate: Nanoscale Morphology in the Swollen State and Use as Exotemplates for Synthesis of Nanostructured Ferric Oxide

Published: March 2012

AbstractThe polymer framework of water‐swollen copolymers of N,N‐dimethylacrylamide, acrylamido‐2‐methylpropanesulfonic acid, and ethylenedimethacrylate (nominal cross‐linking degrees of 4, 8, and 20 mol %) is composed of highly expanded domains, with “pores” not less than 6 nm in diameter. When the 4 % cross‐linked copolymer (DAE 26‐4) is swollen with a 10−4 M solution of 4‐hydroxy‐2,2,6,6‐tetramethylpiperidine‐1‐oxyl (TEMPOL) in water, MeOH, EtOH, or nBuOH, the molecules of the paramagnetic probe rotate rapidly (τ<1000 ps) and as fast as in the bulk liquid in the case of water. The swelling degree of DAE 26‐4 is related to the Hansen solubility parameters of a number of liquids, including linear alcohols up to n‐octanol. It is also found that the rotational correlation time of TEMPOL in the copolymer swollen by water and the lightest alcohols increases with decreasing specific absorbed volume. Time‐domain NMR spectrometry of water‐swollen DAE 26‐4 shows that sorption of only 14 % of the liquid required for its complete swelling is enough for full hydration of the polymer chains. Accordingly, in fully swollen DAE 26‐4 the longitudinal relaxation time of water closely approaches the value of pure water. {13C} CP‐MAS NMR on partially and fully water swollen samples of DAE 26‐4 shows that swelling increases the mobility of the polymer chains, as clearly indicated by the narrowing of the best‐resolved peaks. DAE 26‐4 was used as an exotemplate for the synthesis of nanocomposites composed of the polymer and nanostructured Fe2O3 through a series of ion‐exchange/precipitation cycles. After the first cycle the nanoparticles are 3–4 nm in diameter, with practically unchanged size after subsequent cycles (up to five). In fact, the nanoparticle size never exceeded the diameter of the largest available pores. This suggests that the polymer framework controls the growth of the nanoparticles according to the template‐controlled synthesis scheme. Selected‐area electron diffraction, TEM, and high‐resolution electron microscopy show that the nanostructured inorganic phase is composed of hematite.

AbstractThe synthesis and magnetic characterisation of a series of bis‐μ‐alkoxide bridged MnIII dinuclear complexes of general formula [MnIII2(μ‐OR)2(biphen)2(ROH)x(L)y] (where R=Me, Et; H2biphen=2,2′‐biphenol and L=terminally bonded N‐donor ligand) is described, doubling the literature basis set for this type of complex. Building on these findings we have categorised all known μ‐OR bridged MnIII dinuclear complexes into one of three classifications with respect to their molecular structures. We have then employed DFT and MO calculations to assess all potential magneto‐structural correlations for this class of compound in order to identify the structural requirements for constructing ferromagnetic family members. Our analysis indicates that the most influential parameter which governs the exchange interaction in this class of compounds is the relative orientation of the JT axes of the MnIII atoms. A perpendicular orientation of the JT axes leads to a large ferromagnetic contribution to the exchange. These results also suggest that a large ferromagnetic interaction and a large anisotropy are unlikely to co‐exist in such structural types.

Published: March 2012

AbstractHeterophase polymerizations have gained increasing attention in the past decades, especially as the decoration and functionalization of the particle surface for further applications gets more and more into focus. One promising approach for the functionalization exclusively on the particle surface is the use of surfmers (surfactant and monomer). Herein, we present the synthesis of a new family of surfmers and their use for decorating nanoparticles with phosphonate groups through miniemulsion polymerization. Furthermore the synthesis of a dye‐labeled functional surfmer provided an elegant manner to evaluate and get deeper insights about its copolymerization. Additionally, potential applications of the synthesized particles in biological studies as well as their use as template for biomimetic mineralization are presented.
Biocompatible Triplex Ag@SiO2@mTiO2 Core–Shell Nanoparticles for Simultaneous Fluorescence‐SERS Bimodal Imaging and Drug Delivery

Published: March 2012

AbstractHerein, we report the synthesis of biocompatible triplex Ag@SiO2@mTiO2 core–shell nanoparticles (NPs) for simultaneous fluorescence‐surface‐enhanced Raman scattering (F‐SERS) bimodal imaging and drug delivery. Stable Raman signals were created by typical SERS tags that were composed of Ag NPs for optical enhancement, a reporter molecule of 4‐mercaptopyridine (4‐Mpy) for a spectroscopic signature, and a silica shell for protection. A further coating of mesoporous titania (mTiO2) on the SERS tags offered high loading capacity for a fluorescence dye (flavin mononucleotide) and an anti‐cancer drug (doxorubicin (DOX)), thereby endowing the material with fluorescence‐imaging and therapeutic functions. The as‐prepared F‐SERS dots exhibited strong fluorescence when excited by light at 460 nm whilst a stable, characteristic 4‐Mpy SERS signal was detected when the excitation wavelength was changed to longer wavelength (632.8 nm), both in solution and after incorporation inside living cells. Their excellent biocompatibility was demonstrated by low cytotoxicity against MCF‐7 cells, even at a high concentration of 100 μg mL−1. In vitro cell cytotoxicity confirmed that DOX‐loaded F‐SERS dots had a comparable or even greater therapeutic effect compared with the free drug, owing to the increased cell‐uptake, which was attributed to the possible endocytosis mechanism of the NPs. To the best of our knowledge, this is the first proof‐of‐concept investigation on a multifunctional nanomedicine that possessed a combined capacity for fast and multiplexed F‐SERS labeling as well as drug‐loading for cancer therapy.
Polychloride Monoanions from [Cl3]− to [Cl9]−: A Raman Spectroscopic and Quantum Chemical Investigation
Authors: Brückner Robin , Haller Heike , Ellwanger Mathias , Riedel Sebastian 
Published: March 2012

AbstractPolychloride monoanions stabilized by quaternary ammonium salts are investigated using Raman spectroscopy and state‐of‐the‐art quantum‐chemical calculations. A regular V‐shaped pentachloride is characterized for the [N(Me)4][Cl5] salt, whereas a hockey‐stick‐like structure is tentatively assigned for [N(Et)4][Cl2⋅⋅⋅Cl3−]. Increasing the size of the cation to the quaternary ammonium salts [NPr4]+ and [NBu4]+ leads to the formation of the [Cl3]− anion. The latter is found to be a pale yellow liquid at about 40 °C, whereas all the other compounds exist as powders. Further to these observations, the novel [Cl9]− anion is characterized by low‐temperature Raman spectroscopy in conjunction with quantum‐chemical calculations.
Carbon‐Decorated Single‐Crystalline Ni2P Nanotubes Derived from Ni Nanowire Templates: A High‐Performance Material for Li‐Ion Batteries

Published: March 2012

AbstractSingle‐crystalline Ni2P nanotubes (NTs) were facilely synthesized by using a Ni nanowire template. The mechanism for the formation of the tubular structures was related to the nanoscale Kirkendall effect. These NTs exhibited a core/shell structure with an amorphous carbon layer that was grown in situ by employing oleylamine as a capping agent. Galvanostatic charge/discharge measurements indicated that these Ni2P/C NTs exhibited superior high‐rate capability and good cycling stability. There was still about 310 mAh g−1 retained after 100 cycles at a rate of 5 C. Importantly, the tubular nanostructures and the single‐crystalline nature of the Ni2P NTs were also preserved after prolonged cycling at a relatively high rate. These improvements were attributed to the stable nanotubular structure of Ni2P and the carbon shell, which enhanced the conductivity of Ni2P, suppressed the aggregation of active particles, and increased the electrode stability during cycling.
Sonochemical Synthesis of Ag/AgCl Nanocubes and Their Efficient Visible‐Light‐Driven Photocatalytic Performance

Published: March 2012

AbstractA novel one‐step sonochemical approach to synthesize a plasmonic photocatalyst of AgCl nanocubes (ca. 115 nm in edge length) with a small amount of Ag metal species is presented. The nanoscale Ag/AgCl hybrid photocatalysts with cubic morphology are readily formed under ambient ultrasonic conditions and neither external heat treatment nor reducing agents are required. The size of the Ag/AgCl photocatalysts could be controlled by changing the concentrations of Ag+ ions and polyvinylpyrrolidone molecules in precursor solutions. The compositions, microstructures, influencing factors, and possible growth mechanism of the Ag/AgCl hybrid nanocubes were systematically investigated. The Ag/AgCl photocatalysts show excellent photocatalytic performance for degradation of various dye molecules under visible light.
Amide‐Based Nonheme Cobalt(III) Olefin Epoxidation Catalyst: Partition of Multiple Active Oxidants CoVO, CoIVO, and CoIIIOO(O)CR

AbstractA mononuclear nonheme cobalt(III) complex of a tetradentate ligand containing two deprotonated amide moieties, [Co(bpc)Cl2][Et4N] (1; H2bpc=4,5‐dichloro‐1,2‐bis(2‐pyridine‐2‐carboxamido)benzene), was prepared and then characterized by elemental analysis, IR, UV/Vis, and EPR spectroscopy, and X‐ray crystallography. This nonheme CoIII complex catalyzes olefin epoxidation upon treatment with meta‐chloroperbenzoic acid. It is proposed that complex 1 shows partitioning between the heterolytic and homolytic cleavage of an OO bond to afford CoVO (3) and CoIVO (4) intermediates, proposed to be responsible for the stereospecific olefin epoxidation and radical‐type oxidations, respectively. Moreover, under extreme conditions, in which the concentration of an active substrate is very high, the CoOOC(O)R (2) species is a possible reactive species for epoxidation. Furthermore, partitioning between heterolysis and homolysis of the OO bond of the intermediate 2 might be very sensitive to the nature of the solvent, and the OO bond of the CoOOC(O)R species might proceed predominantly by heterolytic cleavage, even in the presence of small amounts of protic solvent, to produce a discrete CoVO intermediate as the dominant reactive species. Evidence for these multiple active oxidants was derived from product analysis, the use of peroxyphenylacetic acid as the peracid, and EPR measurements. The results suggest that a less accessible CoVO moiety can form in a system in which the supporting chelate ligand comprises a mixture of neutral and anionic nitrogen donors.
